We hypothesized that metachronous colorectal liver metastases (CLM) have different biology after failure of oxaliplatin (FOLFOX) compared to 5-fluorouracil (5-FU) or no chemotherapy for adjuvant treatment of colorectal cancer (CRC). It is unclear whether patients treated with liver resection for metachronous CLM after adjuvant FOLFOX for CRC have worse outcomes than those who received 5-FU or no chemotherapy. We identified 341 patients who underwent hepatectomy for metachronous CLM (disease-free interval ≥12 months, 1993-2010). Mass-spectroscopy genotyping for somatic gene mutations in CLM was performed in a subset of 129 patients. Adjuvant treatment for primary CRC was FOLFOX in 77 patients, 5-FU in 169 patients, and no chemotherapy in 95 patients. Node-positive primary was comparable between FOLFOX and 5-FU but lower in the no-chemotherapy group (P < 0.0001). Median metastasis size was smaller in the FOLFOX group (2.5 cm) than in the 5-FU (3.0 cm) or no-chemotherapy (3.5 cm) groups, (P = 0.008) although prehepatectomy chemotherapy utilization, metastases number, and carcinoembryonic antigen levels were similar. Disease-free survival (DFS) and overall survival (OS) rates after hepatectomy were worse in patients treated with adjuvant FOLFOX [DFS at 3 years: 14% vs 38% (5-FU) vs 45% (no-chemo), OS at 3 years: 58% vs 70% (5-FU) vs 84% (no-chemo)]. On multivariate analysis, adjuvant FOLFOX was associated with worse DFS (P < 0.0001) and OS (P < 0.0001). Mutation analysis revealed ≥1 mutations in 57% of patients (27/47) after FOLFOX, 29% (12/41) after 5-FU, and 32% (13/41) after no chemotherapy (P = 0.011). Adjuvant FOLFOX for primary CRC is associated with a high rate of somatic mutations in liver metastases and inferior outcomes after hepatectomy for metachronous CLM.

Biochemical modulation of 5-fluorouracil (5-FU) by leucovorin (LV) enhances antitumor activity. LV is thus often added to 5-FU-based regimens for the treatment of metastatic colorectal cancer (mCRC). A combination of S-1, oxaliplatin, and LV (SOL) was shown to be feasible, effective, and safe in a previous phase I trial. We therefore conducted a randomized phase II trial to evaluate efficacy and safety of SOL compared with mFOLFOX6. Patients with mCRC and no prior chemotherapy were randomly assigned to receive either SOL or mFOLFOX6. SOL consisted of S-1 (40-60 mg bid) plus oral LV (25 mg bid) for 1 week and oxaliplatin (85 mg/m(2)) on day 1, repeated every 2 weeks. Among 107 patients enrolled from July 2008 through July 2009, 105 (56 in the SOL group and 49 in the mFOLFOX6 group) were eligible and evaluated. The median progression-free survival was 9.6 months in the SOL group and 6.9 months in the mFOLFOX6 group [hazard ratio (HR) 0.83, 95 % confidence interval (CI) 0.49-1.40]. The median overall survival was 29.9 and 25.9 months, respectively (HR 0.91, 95 % CI 0.55-1.49). The response rate was 55 % in both groups. Grade 3 or 4 adverse drug reactions were neutropenia (20 % with SOL vs 41 % with mFOLFOX6), sensory neuropathy (20 vs 2.0 %), anorexia (13 vs 7.8 %), fatigue (11 vs 5.9 %), and diarrhea (11 vs 3.9 %). SOL demonstrated promising efficacy and acceptable toxicity as first-line chemotherapy for mCRC. Further studies of SOL combined with molecular target agents are warranted.

The impact of adjuvant chemotherapy on hepatic function and portal hypertension in patients with stages II-III colon cancer has not been previously described. We conducted a retrospective study to assess the effects of adjuvant FOLFOX chemotherapy on the splenic index (SI) as a surrogate marker for portal hypertension. Stage II-III colorectal cancer patients treated with adjuvant FOLFOX or fluorouracil/leucovorin (5-FU/LV) at Roswell Park Cancer Institute between 2002 and 2006 were identified. Computerizedt omography (CT) scans obtained prior to and at completion of chemotherapy, and every 6 months thereafter were reviewed. Splenic size was evaluated using the SI (SI = length x width x height of the spleen). 40 patients were identified in the FOLFOX group and 23 in the 5-FU/LV group. After 6 months of adjuvant chemotherapy, the mean increase in SI was 45.7 and 16.3% in the FOLFOX and 5-FU/LV groups, respectively (p = 0.0069). SI increased by >100% in 6 patients (15%) in the FOLFOX group versus none in the 5-FU/LV group (p = 0.16). The mean SI at completion of adjuvant chemotherapy was significantly higher in the FOLFOX group than in the 5-FU/LV group (p = 0.007). The mean SI decreased steadily over a period of 2 years after discontinuation of FOLFOX, suggesting potential reversibility of oxaliplatin-induced hepatic injury in this setting. Adjuvant FOLFOX significantly increases the SI in patients with resected colorectal cancer in comparison to adjuvant 5-FU/LV. The increase in SI may be a marker of oxaliplatin-induced hepatic injury and should be investigated further in prospective longitudinal studies of oxaliplatin-based adjuvant chemotherapy.

XELOX (capecitabine + oxaliplatin) and FOLFOX 4 (5-FU + folinic acid + oxaliplatin) have shown similar improvements in survival in patients with metastatic colorectal cancer (MCRC). A US cost-minimization study found that the two regimens had similar costs from a healthcare provider perspective but XELOX had lower costs than FOLFOX4 from a societal perspective, while a Japanese cost-effectiveness study found XELOX had superior cost-effectiveness. This study compared the costs of XELOX and FOLFOX4 in patients with MCRC recently treated in two oncology departments in Hong Kong. Cost data were collected from the medical records of 60 consecutive patients (30 received XELOX and 30 FOLFOX4) from two hospitals. Drug costs, outpatient visits, hospital days and investigations were recorded and expressed as cost per patient from the healthcare provider perspective. Estimated travel and time costs were included in a societal perspective analysis. All costs were classed as either scheduled (associated with planned chemotherapy and follow-up) or unscheduled (unplanned visits or admissions and associated tests and medicines). Costs were based on government and hospital sources and expressed in US dollars (US$). XELOX patients received an average of 7.3 chemotherapy cycles (of the 8 planned cycles) and FOLFOX4 patients received 9.2 cycles (of the 12 planned cycles). The scheduled cost per patient per cycle was $2,046 for XELOX and $2,152 for FOLFOX4, while the unscheduled cost was $240 and $421, respectively. Total treatment cost per patient was $16,609 for XELOX and $23,672 for FOLFOX4; the total cost for FOLFOX4 was 37% greater than that of XELOX. The addition of the societal costs increased the total treatment cost per patient to $17,836 for XELOX and $27,455 for FOLFOX4. Sensitivity analyses showed XELOX was still less costly than FOLFOX4 when using full drug regimen costs, incorporating data from a US model with costs and adverse event data from their clinical trial and with the removal of oxaliplatin from both treatment arms. Capecitabine would have to cost around four times its present price in Hong Kong for the total resource cost of treatment with XELOX to equal that of FOLFOX4. XELOX costs less than FOLFOX4 for this patient group with MCRC from both the healthcare provider and societal perspectives.

Colorectal cancer, fourth leading form of cancer worldwide and is increasing in alarming rate in the developing countries. Treating colorectal cancer has become a big challenge worldwide and several antibody therapies such as bevacizumab, panitumumab and cetuximab are being used with limited success. Moreover, mutation in KRAS gene which is linked with the colorectal cancer initiation and progression further interferes with the antibody therapies. Considering median progression free survival and overall survival in account, this review focuses to identify the most efficient antibody therapy in combination with chemotherapy (FOLFOX-4) in KRAS mutated colorectal cancer patients. The bevacizumab plus FOLFOX-4 therapy shows about 9.3 months and 8.7 months of progression free survival for KRAS wild and mutant type, respectively. The overall survival is about 34.8 months for wild type whereas for the mutant it is inconclusive for the same therapy. In comparison, panitumumab results in better progression-free survival which is about (9.6 months) and overall survival is about (23.9 months) for the wild type KRAS and the overall survival is about 15.5 months for the mutant KRAS . Cetuximab plus FOLFOX-4 therapy shows about 7.7 months and 5.5 months of progression-free survival for wild type KRAS and mutant type, respectively. Thus, panitumumab shows significant improvement in overall survival rate for wild type KRAS , validating as a cost effective therapeutic for colorectal cancer therapy. This review depicts that panitumumab along with FOLFOX-4 has a higher response in colorectal cancer patients than the either of the two monoclonal antibodies plus FOLFOX-4.

The clinical benefit of cetuximab combined with oxaliplatin-based chemotherapy remains under debate. The aim of the present multicenter open-label Phase II study was to explore the efficacy and safety of biweekly administration of cetuximab and mFOLFOX-6 or XELOX as first-line chemotherapy in patients with metastatic colorectal cancer. Sixty-two patients with previously untreated KRAS/BRAF wild-type metastatic colorectal cancer were recruited to the study between April 2010 and May 2011. Patients received one of two treatment regimens, either cetuximab plus mFOLFOX-6 (FOLFOX + Cmab) or cetuximab plus biweekly XELOX (XELOX + Cmab), according to their own preference. Treatment was continued until disease progression or the appearance of intolerable toxicities. The primary endpoint was response rate; secondary endpoints were progression-free survival, overall survival, disease control rate, dose intensity, conversion rate to surgical resection, and safety. The response rates in the FOLFOX + Cmab (n = 37) and XELOX + Cmab (n = 25) groups were 64.9 % (24/37) and 72.0 % (18/25), respectively. The median PFS in the FOLFOX + Cmab and XELOX + Cmab groups was 13.1 months (95 % confidence interval [CI] 12.1-17.5) and 13.4 months (95 % CI 10.1-17.9), respectively. Neutropenia was the most frequent grade 3/4 adverse event in both groups (33.9 %), followed by anorexia, acneiform eruption, skin fissure and paronychia. A waterfall plot of tumor diameter showed prominent shrinkage of the tumors in 88.7 % of patients. The results of the present study indicate that biweekly cetuximab plus mFOLFOX-6/XELOX is an effective and tolerable treatment regimen. Biweekly administration of cetuximab requires only one hospital visit every 2 weeks, and may become a convenient treatment option for patients with KRAS/BRAF wild-type metastatic colorectal cancer.

The prognostic significance of glandular differentiation in urothelial carcinoma (UC) is controversial, and thus far there is no established treatment strategy against metastasis of glandular component. We describe here a case of metastatic UC with glandular differentiation that had histological disappearance of adenocarcinoma components at autopsy after sequential chemotherapy with S-1 and cisplatin (CDDP) and with mFOLFOX6 (fluorouracil, oxaliplatin, and leucovorin) plus bevacizumab (mFOLFOX6+Bev). A 62-year-old Asian male was diagnosed with invasive UC with glandular differentiation (T2N0M0) by radical cystectomy and ileal conduit, and careful follow-up observation was made. Eight years after radical operation, peritoneal metastases occurred, and a biopsy specimen using colon fiber revealed high-grade adenocarcinomas with an immunohistochemical profile that included positivity for cytokeratin 7 (CK7) and negativity for cytokeratin 20 (CK20) and uroplakin, which was identical to the radical cystectomy specimen. Thus, he received combination chemotherapy consisting of S-1 and CDDP; however, the peritoneal metastasis worsened after 2 cycles. Therefore, second-line mFOLFOX6+Bev chemotherapy was performed for a total of 5 courses. In spite of this, the patient died, and the final diagnosis by autopsy was multiple metastases of infiltrating pure UC to the lung, bone, and peritoneum. Interestingly, there were no pathological findings of adenocarcinoma, and the immunohistochemical profile of the metastatic lesions was identical to that of the previous specimens from the bladder and colon. This suggests that sequential chemotherapy of S-1 and CDDP and second-line mFOLFOX6+Bev might be a feasible option in metastatic UC with glandular differentiation. PMID:29515396

4-Acetylantroquinonol B (4-AAQB), closely related to the better known antroquinonol, is a bioactive isolate of the mycelia of Antrodia camphorata, a Taiwanese mushroom with documented anti-inflammatory, hypoglycemic, vasorelaxative, and recently demonstrated, antiproliferative activity. Based on its traditional use, we hypothesized that 4-AAQB may play an active role in the suppression of cellular transformation, tumor aggression and progression, as well as chemoresistance in colorectal carcinoma (CRC). In this study, we investigated the antiproliferative role of 4-AAQB and its underlying molecular mechanism. We also compared its anticancer therapeutic potential with that of antroquinonol and the CRC combination chemotherapy of choice — folinicmore » acid, fluorouracil and oxaliplatin (FOLFOX). Our results showed that 4-AAQB was most effective in inhibiting tumor proliferation, suppressing tumor growth and attenuating stemness-related chemoresistance. 4-AAQB negatively regulates vital oncogenic and stem cell maintenance signal transduction pathways, including the Lgr5/Wnt/β-catenin, JAK–STAT, and non-transmembrane receptor tyrosine kinase signaling pathways, as well as inducing a dose-dependent downregulation of ALDH and other stemness related factors. These results were validated in vivo, with animal studies showing 4-AAQB possessed comparable tumor-shrinking ability as FOLFOX and potentiates ability of the later to reduce tumor size. Thus, 4-AAQB, a novel small molecule, projects as a potent therapeutic agent for monotherapy or as a component of standard combination chemotherapy. - Highlights: • 4-Acetylantroquinonol B (4-AAQB) suppressed tumor cell proliferation. • 4-AAQB regulates oncogenic and stem cell maintenance signal pathways. • 4-AAQB negatively regulates Lgr5/Wnt/β-catenin and JAK–STAT pathways. • 4-AAQB reduced ALDH and other stemness related factor expression. • In vivo, 4-AAQB has comparable tumor-shrinking ability as FOLFOX.« less

SIRFLOX was a randomized, multicenter trial designed to assess the efficacy and safety of adding selective internal radiation therapy (SIRT) using yttrium-90 resin microspheres to standard fluorouracil, leucovorin, and oxaliplatin (FOLFOX)-based chemotherapy in patients with previously untreated metastatic colorectal cancer. Chemotherapy-naïve patients with liver metastases plus or minus limited extrahepatic metastases were randomly assigned to receive either modified FOLFOX (mFOLFOX6; control) or mFOLFOX6 plus SIRT (SIRT) plus or minus bevacizumab. The primary end point was progression-free survival (PFS) at any site as assessed by independent centralized radiology review blinded to study arm. Between October 2006 and April 2013, 530 patients were randomly assigned to treatment (control, 263; SIRT, 267). Median PFS at any site was 10.2 v 10.7 months in control versus SIRT (hazard ratio, 0.93; 95% CI, 0.77 to 1.12; P = .43). Median PFS in the liver by competing risk analysis was 12.6 v 20.5 months in control versus SIRT (hazard ratio, 0.69; 95% CI, 0.55 to 0.90; P = .002). Objective response rates (ORRs) at any site were similar (68.1% v 76.4% in control v SIRT; P = .113). ORR in the liver was improved with the addition of SIRT (68.8% v 78.7% in control v SIRT; P = .042). Grade ≥ 3 adverse events, including recognized SIRT-related effects, were reported in 73.4% and 85.4% of patients in control versus SIRT. The addition of SIRT to FOLFOX-based first-line chemotherapy in patients with liver-dominant or liver-only metastatic colorectal cancer did not improve PFS at any site but significantly delayed disease progression in the liver. The safety profile was as expected and was consistent with previous studies. © 2016 by American Society of Clinical Oncology.

We retrospectively analysed 153 patients with metastatic colorectal cancer who received FOLFOX with or without bevacizumab as first-line chemotherapy. Several background characteristics and chemotherapy features (grade of neutropaenia, use of bevacizumab or irinotecan, re-introduction of FOLFOX, and tumour progression) as time-varying covariates were analysed as potential prognostic factors. Of the 153 patients, mild neutropaenia (grade 1-2) occurred in 60 patients (39%) and severe neutropaenia (grade 3-4) occurred in 46 patients (30%). The other 47 patients (31%) did not experience neutropaenia. According to a multivariate Cox model with time-varying covariates, hazard ratios (HRs) of death were 0.55 (95% confidence interval (CI), 0.31-0.98; P=0.044) for patients with mild neutropaenia and 0.35 (95% CI, 0.18-0.66; P=0.002) for those with severe neutropaenia. Both mild and severe neutropaenia during chemotherapy are associated with improved survival in patients with MCRC. Prospective trials are required to assess whether dosing adjustments based on neutropaenia may improve chemotherapy efficacy.

To validate established cutoff levels of thymidylate synthase (TS) and excision repair cross-complementing (ERCC-1) intratumoral mRNA expressions in tumor samples from metastatic colorectal cancer (mCRC) patients treated with PTK787/ZK222584 (PTK/ZK). From 122 samples of patients with mCRC enrolled in CONFIRM-1 (Colorectal Oral Novel Therapy for the Inhibition of Angiogenesis and Retarding of Metastases) or CONFIRM-2, mRNA was isolated of microdissected formalin-fixed paraffin-embedded samples and quantitated using TaqMan-based technology. Existing TS and ERCC-1 cutoff levels were tested for their prognostic value in first-line and second-line therapy. TS expression was associated with overall survival (OS) in first-line, but not second-line therapy. ERCC-1 was associated with OS in patients treated with first-line and second-line FOLFOX4. In first-line FOLFOX4, combination of high TS and/or high ERCC-1 was associated with shorter OS. A correlation was observed between ERCC-1 expression and benefit from PTK/ZK+FOLFOX4 treatment. TS and ERCC-1 expression is associated with clinical outcome in mCRC. Baseline TS and ERCC-1 levels may allow the selection of patients who benefit from FOLFOX4 chemotherapy.

The role of adjuvant chemotherapy for patients with rectal cancer is controversial, especially when used after preoperative chemoradiotherapy. Fluoropyrimidine-based adjuvant chemotherapy, including fluorouracil and leucovorin, has been widely used; however, the addition of oxaliplatin to fluorouracil and leucovorin (FOLFOX), a standard adjuvant regimen for colon cancer, has not been tested in rectal cancer. We aimed to compare the efficacy and safety of adjuvant fluorouracil and leucovorin with that of FOLFOX in patients with locally advanced rectal cancer after preoperative chemoradiotherapy. In this open-label, multicentre, phase 2, randomised trial, patients with postoperative pathological stage II (ypT3-4N0) or III (ypTanyN1-2) rectal cancer after preoperative fluoropyrimidine-based chemoradiotherapy and total mesorectal excision were recruited and randomly assigned (1:1) via a web-based software platform to receive adjuvant chemotherapy with either four cycles of fluorouracil and leucovorin (fluorouracil 380 mg/m(2) and leucovorin 20 mg/m(2) on days 1-5, every 4 weeks) or eight cycles of FOLFOX (oxaliplatin 85 mg/m(2), leucovorin 200 mg/m(2), and fluorouracil bolus 400 mg/m(2) on day 1, and fluorouracil infusion 2400 mg/m(2) for 46 h, every 2 weeks). Stratification factors were pathological stage (II vs III) and centre. Neither patients nor investigators were masked to group assignment. The primary endpoint was 3-year disease-free survival, analysed by intention to treat. This study is fully enrolled, is in long-term follow-up, and is registered with ClinicalTrials.gov, number NCT00807911. Between Nov 19, 2008, and June 12, 2012, 321 patients were randomly assigned to fluorouracil and leucovorin (n=161) and FOLFOX (n=160). 141 (95%) of 149 patients in the fluorouracil plus leucovorin group and 141 (97%) of 146 in the FOLFOX group completed all planned cycles of adjuvant treatment. Median follow-up was 38·2 months (IQR 26·4-50·6). 3-year disease-free survival was 71·6% (95% CI 64·6-78·6) in the FOLFOX group and 62·9% (55·4-70·4) in the fluorouracil plus leucovorin group (hazard ratio 0·657, 95% CI 0·434-0·994; p=0·047). Any grade neutropenia, thrombocytopenia, fatigue, nausea, and sensory neuropathy were significantly more common in the FOLFOX group than in the fluorouracil plus leucovorin group; however, we noted no significant difference in the frequency of these events at grade 3 or 4. The most common grade 3 or worse adverse events were neutropenia (38 [26%] of 149 patients in the fluorouracil plus leucovorin group vs 52 [36%] of 146 patients in the FOLFOX group), leucopenia (eight [5%] vs 12 [8%]), febrile neutropenia (four [3%] vs one [<1%]), diarrhoea (four [3%] vs two [1%]), and nausea (one [<1%] vs two [1%]). Adjuvant FOLFOX improves disease-free survival compared with fluorouracil plus leucovorin in patients with locally advanced rectal cancer after preoperative chemoradiotherapy and total mesorectal excision, and warrants further investigation.

 We evaluated four representative chemotherapy regimens for unresectable advanced or recurrent KRAS-wild type colorectal cancer: mFOLFOX6, mFOLFOX6+bevacizumab (Bmab), cetuximab (Cmab), or panitumumab (Pmab). We employed a decision analysis method in combination with clinical and economic evidence. The health outcomes of the regimens were analyzed on the basis of overall and progression-free survival. The data were drawn from the literature on randomized controlled clinical trials of the above-mentioned drugs. The total costs of the regimens were calculated on the basis of direct costs obtained from the medical records of patients diagnosed with unresectable advanced or recurrent colorectal cancer at Yamagata University Hospital and Yamagata Prefecture Central Hospital. Cost effectiveness was analyzed using a Markov chain Monte Carlo (MCMC) method. The study was designed from the viewpoint of public medical care. The MCMC analysis revealed that expected life months and expected cost were 20 months/3,527,119 yen for mFOLFOX6, 27 months/8,270,625 yen for mFOLFOX6+Bmab, 29 months/13,174,6297 yen for mFOLFOX6+Cmab, and 6 months/12,613,445 yen for mFOLFOX6+Pmab. Incremental costs per effectiveness ratios per life month against mFOLFOX6 were 637,592 yen for mFOLFOX6+Bmab, 1,075,162 yen for mFOLFOX6+Cmab, and 587,455 yen for mFOLFOX6+Pmab. Compared to the conventional mFOLFOX6 regimen, molecular-targeted drug regimens provide better health outcomes, but the cost increases accordingly. mFOLFOX 6+Pmab is the most cost-effective regimen among those surveyed in this study.

Often curative treatment for locally advanced resectable esophageal or gastro-esophageal junctional cancer consists of concurrent neoadjuvant radiotherapy and chemotherapy followed by surgery. Currently, one of the most commonly used chemotherapy regimens in this setting is a combination of a fluoropyrimidin and of a platinum analogue. Due to the promising results of the recent CROSS trial, another regimen combining paclitaxel and carboplatin is also widely used by European and American centers. No clinical study has shown the superiority of one treatment over the other. The objective of this Phase II study is to clarify clinical practice by comparing these two chemotherapy treatments. Our aim is to evaluate, in operable esophageal and gastro-esophageal junctional cancer, the complete resection rate and severe postoperative morbidity rate associated with these two neoadjuvant chemotherapeutic regimens (carboplatin-paclitaxel or fluorouracil-oxaliplatin-folinic acid) when each is combined with the radiation regime utilized in the CROSS trial. PROTECT is a prospective, randomized, multicenter, open arms, phase II trial. Eligible patients will have a histologically confirmed adenocarcinoma or squamous cell carcinoma and be treated with neoadjuvant radiochemotherapy followed by surgery for stage IIB or stage III resectable esophageal cancer. A total of 106 patients will be randomized to receive either 3 cycles of FOLFOX combined to concurrent radiotherapy (41.4 Grays) or carboplatin and paclitaxel with the same radiation regimen, using a 1:1 allocation ratio. This ongoing trial offers the unique opportunity to compare two standards of chemotherapy delivered with a common regimen of preoperative radiation, in the setting of operable locally advanced esophageal or gastro-esophageal junctional tumors.

A 38-year-old man was given a diagnosis of as sigmoid colon cancer and underwent sigmoid colectomy. Post-operative pathological staging was stage IIIb. He then underwent adjuvant chemotherapy. One year and 4 months after the surgery, CT scans revealed multiple liver and lung metastases. He was given mFOLFOX6+bevacizumab, which was changed later to FOLFIRI+bevacizumab. After these chemotherapies, he was admitted to the hospital due to sudden abdominal pain and high grade fever. Obstructive jaundice was initially diagnosed, but detailed study of initial CT revealed intragastric wall abscess. After the drainage of the abscess, his conditions improved. We speculated that the abscess formation was caused by mucosal damage due to bevacizumab.

mFOLFOX6 Plus Panitumumab Versus 5-FU/LV Plus Panitumumab After Six Cycles of Frontline mFOLFOX6 Plus Panitumumab: A Randomized Phase II Study of Patients With Unresectable or Advanced/Recurrent, RAS Wild-type Colorectal Carcinoma (SAPPHIRE)-Study Design and Rationale.

In Japan, oxaliplatin (OXA)/5-fluorouracil (5-FU)/leucovorin (LV)-the mFOLFOX6 regimen-is the most frequently used first-line chemotherapy backbone for metastatic colorectal cancer. However, peripheral nerve disorders caused by OXA during mFOLFOX6 therapy can decrease patients' quality of life. OXA can be safely discontinued from a FOLFOX regimen after 6 cycles during first-line therapy. Also, for patients who discontinue OXA without having experienced peripheral nerve disorders, reintroducing OXA in the later stages of treatment could remain an option. The study is a phase II, multicenter, open-label, parallel-group, randomized, controlled exploratory study comparing the efficacy and safety of mFOLFOX6 plus panitumumab and 5-FU/LV plus panitumumab in patients with chemotherapy-naïve, unresectable, advanced or recurrent colorectal carcinoma of RAS wild-type (SAPPHIRE; ClinicalTrials.gov identifier, NCT02337946). Eligible patients will receive 6 cycles of mFOLFOX6 plus panitumumab combination therapy, followed by 1:1 randomization to either further treatment with mFOLFOX6 plus panitumumab or discontinuation of OXA and treatment with 5-FU/LV plus panitumumab. Up to 100 randomized patients will receive treatment for approximately 12 months or until any of the criteria for treatment discontinuation have been met. The primary endpoint is progression-free survival rate at 9 months after the day of randomization. The secondary endpoints are progression-free survival, overall survival, response rate, and interval to treatment failure. Safety will be evaluated according to the incidence and severity of adverse events, including the incidence of peripheral nerve and skin disorders. Additional endpoints will include maintenance of performance status, continuation of OXA in the mFOLFOX6 plus panitumumab group, and continuation of panitumumab in both groups.

A multicenter phase II clinical study was performed in patients with T3 or T4 stage II/III rectal cancer to evaluate the efficacy and safety of neoadjuvant chemotherapy with 5-fluorouracil, levofolinate, and oxaliplatin (mFOLFOX6). Patients received four 2-week cycles of mFOLFOX6 therapy (oxaliplatin at 85 mg/m 2  + leucovorin at 200 mg/m 2  + fluorouracil as a 400 mg/m 2 bolus followed by infusion of 2400 mg/m 2 over 46 h, all on Day 1). They were evaluated by computed tomography after completion of the fourth cycle. If there was no disease progression, two additional cycles were administered and then surgery was performed. Adjuvant chemotherapy was generally administered for 6 months using appropriate regimens at the discretion of the physician. mFOLFOX6 therapy was given to 52 patients with locally advanced rectal cancer. The preoperative response rate was 48.8% and the operation rate was 80.8%. Serious adverse events of Grade 3-4 were neutropenia (n = 5), leukopenia (n = 1), thrombocytopenia (n = 1), febrile neutropenia (n = 1), nausea (n = 1), vomiting (n = 1), and peripheral neuropathy (n = 2). The R0 resection rate, pathologic complete response rate, and sphincter preservation rate were 91.0, 11.9, and 73.8%, respectively. Postoperative complications were tolerable. The present results suggested that neoadjuvant therapy with mFOLFOX6 is safe and effective, representing a reasonable treatment option for locally advanced rectal cancer.

To determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT) and efficacy of sorafenib in combination with FOLFOX4 (oxaliplatin/leucovorin (LV)/5-fluorouracil) as first-line treatment for advanced gastric cancer, we performed a phase I dose-finding study in nine evaluable patients with unresectable locally advanced or metastatic gastric cancer or gastroesophageal junction adenocarcinoma. According to modified Fibonacci method, the design of this study was to guide elevation of the sorafenib dosage to the next level (from 200 mg twice daily to 400 mg twice daily and then, if tolerated, 600 mg twice daily). If the patient achieved complete response (CR), partial response (PR) or stable disease (SD) after eight cycles of treatment, combination chemotherapy was scheduled to be discontinued and sorafenib monotherapy continued at the original dose until either disease progression or unacceptable toxicity. In sorafenib 200 mg twice daily group, DLT was observed in 1 of 6 patients, and in 400 mg twice daily group, it was observed in 2 of 3 patients. Seven of 9 (77.8%) evaluable patients achieved PR, with a median overall survival (OS) of 11.8 [95% confidence interval (CI): 8.9-14.7] months. Common adverse effects include hand-foot syndrome, leukopenia, neutropenia, anorexia, and nausea. Twice-daily dosing of sorafenib 200 mg in combination with FOLFOX4 was proven effective and safe for the treatment of advanced gastric cancer, and could be an appropriate dosage for subsequent phase II clinical studies.

We measured health utility scores of colorectal cancer (CRC) patients from a societal perspective in Japan. Twenty-five states of health were described: four metastatic states without severe adverse events (AEs), 16 metastatic states with Grade 3/4 AEs, four adjuvant states, and one terminal state. A total of 1,500 respondents stratified by age and gender were recruited randomly from the largest Web-panel in Japan. Respondents were allocated randomly to three of the 25 health states and answered questionnaires by standard gamble (SG) and time trade-off (TTO) methods. Although utility scores of metastatic CRC receiving XELOX (capecitabine plus oxaliplatin) chemotherapy were 0.48(SG and TTO) (with stoma) and 0.57(SG) or 0.59(TTO) (without stoma), utility scores of those receiving FOLFOX4 (5-fluorouracil/folinic acid and oxaliplatin) chemotherapy were 0.42(SG) or 0.43(TTO) (with stoma) and 0.52(SG) or 0.53(TTO) (without stoma). These differences between XELOX and FOLFOX4 were statistically significant (P = 0.0198 in SG and P = 0.0059 in TTO). Stage 3/4 AEs decreased utility scores to 0.35-0.4 and 0.4-0.45 in the presence and absence of stoma, respectively. XELOX was generally considered a significantly preferable chemotherapy regimen compared to FOLFOX4 for CRC in Japan. Almost all Grade 3/4 AEs and stoma significantly decreased utility scores. These differences are dependent on the accuracy of the health state description and to confirm these results. In future research, it would be preferable that preference-based HRQoL measures are used directly in patients if utility scores are practically measurable by such method.

Purpose Reduction of adjuvant treatment duration may decrease toxicities without loss of efficacy in stage III colon cancer. This could offer clear advantages to patients and health care providers. Methods In International Duration Evaluation of Adjuvant Chemotherapy (IDEA) France, as part of the IDEA international collaboration, patient with colon cancer patients were randomly assigned to 3 and 6 months of modified FOLFOX6 (mFOLFOX6: infusional fluorouracil, leucovorin, and oxaliplatin) or capecitabine plus oxaliplatin (CAPOX) by physician choice. The primary end point was disease-free survival (DFS), and analyses were descriptive. Results A total of 2,010 eligible patients received either 3 or 6 months of chemotherapy (modified intention-to-treat population); 2,000 (99%) had stage III colon cancer (N1: 75%, N2: 25%); 1,809 (90%) received mFOLFOX6, and 201 (10%) received CAPOX. The median age was 64 years, and the median follow-up time was 4.3 years. Overall, 94% (3 months) and 78% (6 months) of patients completed treatment (fluoropyrimidines ± oxaliplatin). Maximal grade 2 and 3 neuropathy rates were 28% and 8% in the 3-month arm and 41% and 25% in the 6-month arm ( P < .001). Final rates of residual neuropathy greater than grade 1 were 3% in the 3-month arm and 7% in the 6-month arm ( P < .001). There were 578 DFS events: 314 and 264 in the 3- and 6-month arms, respectively. The 3-year DFS rates were 72% and 76% in the 3- and 6-month arms, respectively (hazard ratio [HR], 1.24; 95% CI, 1.05 to 1.46; P = .0112). In the 3 and 6-month arms, respectively, for patients who received mFOLFOX6, the 3-year DFS rates were 72% and 76% (HR, 1.27; 95% CI, 1.07 to 1.51); for the T4 and/or N2 population, they were 58% and 66% (HR, 1.44; 95% CI, 1.14 to 1.82); and for the T1-3N1 population, they were 81% and 83% (HR, 1.15; 95% CI, 0.89 to 1.49). Conclusion IDEA France, in which 90% of patients received mFOLFOX6, shows superiority of 6 months of adjuvant chemotherapy compared with 3 months, especially in the T4 and/or N2 subgroups. These results should be considered alongside the international IDEA collaboration data.

Despite the improvements in diagnosis and treatment, colorectal cancer (CRC) is the second cause of cancer deaths in both sexes. Therefore, research in this field remains of great interest. The approval of bevacizumab, a humanized anti-vascular endothelial growth factor (VEGF) monoclonal antibody, in combination with a fluoropyrimidine-based chemotherapy in the treatment of metastatic CRC has changed the oncology practice in this disease. However, the efficacy of bevacizumab-based treatment, has thus far been rather modest. Efforts are ongoing to understand the better way to combine bevacizumab and chemotherapy, and to identify valid predictive biomarkers of benefit to avoid unnecessary and costly therapy to nonresponder patients. The BRANCH study in high-risk locally advanced rectal cancer patients showed that varying bevacizumab schedule may impact on the feasibility and efficacy of chemo-radiotherapy. OBELICS is a multicentre, open-label, randomised phase 3 trial comparing in mCRC patients two treatment arms (1:1): standard concomitant administration of bevacizumab with chemotherapy (mFOLFOX/OXXEL regimen) vs experimental sequential bevacizumab given 4 days before chemotherapy, as first or second treatment line. Primary end point is the objective response rate (ORR) measured according to RECIST criteria. A sample size of 230 patients was calculated allowing reliable assessment in all plausible first-second line case-mix conditions, with a 80% statistical power and 2-sided alpha error of 0.05. Secondary endpoints are progression free-survival (PFS), overall survival (OS), toxicity and quality of life. The evaluation of the potential predictive role of several circulating biomarkers (circulating endothelial cells and progenitors, VEGF and VEGF-R SNPs, cytokines, microRNAs, free circulating DNA) as well as the value of the early [(18)F]-Fluorodeoxyglucose positron emission tomography (FDG-PET) response, are the objectives of the traslational project. Overall this study could optimize bevacizumab scheduling in combination with chemotherapy in mCRC patients. Moreover, correlative studies could improve the knowledge of the mechanisms by which bevacizumab enhance chemotherapy effect and could identify early predictors of response.

Preoperative chemoradiotherapy followed by total mesorectal excision (TME) is the standard treatment for stage III lower rectal cancer worldwide. However, in Japan, the standard treatment is TME with lateral pelvic lymph node dissection (LPLD) followed by adjuvant chemotherapy. We examined the safety and efficacy of adjuvant therapy with oxaliplatin, leucovorin, and 5-fluorouracil (modified FOLFOX6) after TME with LPLD. This retrospective study included 33 patients who received modified FOLFOX6 after TME with LPLD for stage III lower rectal cancer. The overall completion rate of 12 cycles of adjuvant modified FOLFOX6 was 76%. Grade 3 or 4 neutropenia was observed in eight patients (24%). Sensory neuropathy was observed in 32 patients (97%) with 4 (12%) having a grade 3 event. The disease-free survival (DFS) rate was 45% at 3 years. Adjuvant modified FOLFOX6 was feasible in patients with stage III lower rectal cancer after TME with LPLD. Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

The International Duration Evaluation of Adjuvant chemotherapy project investigated whether a shorter duration of oxaliplatin-based adjuvant chemotherapy was as effective as 6 months of identical chemotherapy for resected stage III colon cancer. As part of this project, we report safety data from the Japanese ACHIEVE study (JFMC47-1202-C3). ACHIEVE was an open-label, multicentre trial randomising patients with stage III colon cancer to receive 3 m or 6 m of mFOLFOX6/CAPOX after surgery. Choice of regimen was declared before randomisation by a site investigator. Between August 2012 and June 2014, 1313 patients were enrolled and, of those, 1277 were analysed for the safety analysis, with 635 in arm 6 (mFOLFOX6, n=158; CAPOX, n=477) and 642 in arm 3 (mFOLFOX6, n=161; CAPOX, n=481). Grade 3 or worse peripheral sensory neuropathy (PSN) developed in 5%/0.6% of patients receiving mFOLFOX6 in arm 6/3 (p=0.019) and 6%/1% of those receiving CAPOX in arm 6/3 (p<0.001). Similarly, grade 2 or worse PSN developed in 36%/11% of patients receiving mFOLFOX6 in arm 6/3 (p<0.001) and 37%/14% of those receiving CAPOX in arm 6/3 (p<0.001). An association between baseline creatinine clearance (CCr) and adverse events (AEs) was found that patients with CAPOX were significantly more likely to develop AEs ≥grade 3 when they had a CCr ≤50 (OR 1.67; p=0.048). We confirmed in the Japanese population that the shorter duration of adjuvant chemotherapy resulted in a significant reduction of PSN. In patients with CAPOX, renal function was significantly related to severe AEs. UMIN000008543, Results.

Background: This study aims to evaluate the effectiveness of adenosine triphosphate-based chemotherapy response assay (ATP-CRA)-guided neoadjuvant chemotherapy for increasing resectability in patients with unresectable colorectal liver metastasis. Patients and methods: Patients were randomised into two groups: Group A was treated by conventional chemotherapy regimen and Group B was treated by chemotherapy regimen according to the ATP-CRA. Three chemotherapeutic agents (5-fluorouracil, oxaliplatin and irinotecan) were tested by ATP-CRA and more sensitive agents were selected. Either FOLFOX or FOLFIRI was administered. Between Group A and B, treatment response and resectability were compared. Results: Between November 2008 and October 2010, a total 63 patients were randomised to Group A (N=32) or Group B (N=31). FOLFOX was more preferred in Group A than in Group B (26 out of 32 (81.3%) vs 20 out of 31 (64.5%)). Group B showed better treatment response than Group A (48.4% vs 21.9%, P=0.027). The resectability of hepatic lesion was higher in Group B (35.5% vs 12.5%, P=0.032). Mean duration from chemotherapy onset to the time of liver resection was 11 cycles (range 4–12) in Group A and 8 cycles (range 8–16) in Group B. Conclusion: This study showed that tailored-chemotherapy based on ATP-CRA could improve the treatment response and resectability in initially unresectable colorectal liver metastasis. PMID:22068817

There is limited experience in treating advanced colorectal cancer diagnosed during pregnancy because it is a rare occurrence; however, the incidence of colorectal cancer complicating pregnancy is expected to increase in the future. The combination of cancer and pregnancy is complicated and causes many dilemmas and concerns for the physician and patient. A delay in treatment may compromise maternal survival; however, therapy for the cancer may be harmful to the fetus. We present a case of a 26-year-old woman pregnant with twins who was diagnosed with metastatic colon cancer and treated with 5-fluorouracil, leukovorin, and oxaliplatin (FOLFOX) from 13 weeks gestational age to birth. The patient gave birth to healthy twins without malformations at 33 weeks gestational age. At follow-up examination, the 2-year-old twins are developing normally. The patient herself died 1 year after the initial cancer diagnosis. This shows a case in which the administration of FOLFOX during the second and third trimester of pregnancy caused no fetal harm. These findings are similar to those of previous studies in which systemic chemotherapy administered during the second and third trimester was relatively safe. However, we know that chemotherapy should be avoided during the first trimester. Copyright © 2011 Elsevier Inc. All rights reserved.

To evaluate the efficacy and safety of upfront mFOLFOX6 followed by short-course radiotherapy (SCRT) and surgery in patients with locally advanced rectal cancer and liver-only metastases. This single-arm phase II study involved 32 patients. mFOLFOX6 was administered for four cycles followed by SCRT and another four cycles of mFOLFOX6. Surgery was performed 4-6 weeks after the last chemotherapy cycle. The primary endpoint was complete (R0) resection rate. Secondary endpoints were response rate, progression-free survival (PFS), overall survival (OS), and complication rates. Surgical resection of the rectum and liver was performed in 25 patients (78%) and R0 resection was achieved in 20 patients (63%). Local tumor downstaging was observed in 54% of patients. Median OS and PFS were 38 and 9 months, respectively. One patient discontinued treatment due to toxicity and no treatment-related deaths occurred. Patients who progressed after 4 cycles of mFOLFOX6 were less likely to receive resection. This regimen was safe and effective in inducing local tumor response and achieving R0 resection in this patient population. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Chemotherapy used during chemoradiotherapy (CRT) is adequate for radiosensitisation, but suboptimal for systemic control. The aim of this phase II study was to assess tolerability, local/systemic benefits, of a novel regimen delivering interdigitating intensive chemotherapy with radical CRT. Eligible pts had untreated synchronous symptomatic primary/metastatic rectal cancer. A total of 12 weeks of treatment with split-course pelvic CRT (total 50.4 Gy with concurrent oxaliplatin and 5-FU infusion) alternating with FOLFOX chemotherapy. All pts staged with CT, MRI and FDG-PET pre and post treatment. Twenty-six pts were treated. Rectal primary MRI stage: T3 81% and T4 15%. Liver metastases in 81%. Twenty-four pts (92%) completed the 12-week regimen. All patients received planned RT dose, and for both agents over 88% of patients achieved a relative dose intensity of >75%. Grade 3 toxicities: neutropenia 23%, diarrhoea 15%, and radiation skin reaction 12%. Grade 4 toxicity: neutropenia 15%. FDG-PET metabolic response rate for rectal primary 96%, and for metastatic disease 60%. Delivery of interdigitating chemotherapy with radical CRT was feasible to treat both primary and metastatic rectal cancer. High completion and response rates were encouraging.

Introduction Cetuximab-based chemotherapy showed a statistically significantly higher response rate compared with chemotherapy such as FOLFOX. Therefore, FOLFOX plus cetuximab is suspected to be the best regimen to alleviate tumor-related symptoms with a high response rate. Case Report Here we present the results of 8 consecutive patients with metastatic colorectal cancer with poor performance status and/or severe complications who were treated with first-line FOLFOX with cetuximab. Six of 8 patients achieved an apparent clinical benefit, including radiological response and symptoms improvement. Two patients with BRAF mutation could achieve neither clinical benefit nor radiological response. Conclusion Although an optimal line of therapy with cetuximab is unclear yet with bevacizumab in mind, we propose that patients who need a tumor response to alleviate their symptoms due to advanced disease might be candidates for first-line cetuximab-based therapy as shown in our cases. Additionally, patients with BRAF mutant tumors might be important candidates for novel targeted therapy in the future to improve their poor prognosis. PMID:21347194

Background Sunitinib is an oral inhibitor of tyrosine kinase receptors implicated in tumor proliferation, angiogenesis, and metastasis. In this randomized, multicenter, open-label Phase IIb study, sunitinib plus mFOLFOX6 (oxaliplatin plus leucovorin plus 5-fluorouracil) was compared with bevacizumab plus mFOLFOX6 as first-line therapy in patients with metastatic colorectal cancer. Methods Patients were stratified by performance status, baseline lactate dehydrogenase level, and prior adjuvant treatment, and randomized 1:1 to receive sunitinib 37.5 mg/day for 4 weeks on and 2 weeks off plus mFOLFOX6 every 2 weeks or bevacizumab 5 mg/kg every 2 weeks plus mFOLFOX6 every 2 weeks. The primary endpoint was progression-free survival. Secondary endpoints included objective response rate, overall survival, safety, and quality of life. Results Enrollment was closed early following accrual of 191 patients, based on an interim analysis showing an inferior trend in the primary progression-free survival efficacy endpoint for sunitinib. Ninety-six patients were randomized to sunitinib plus mFOLFOX6 and 95 to bevacizumab plus mFOLFOX6. Median progression-free survival was 9.3 months and 15.4 months, respectively, but the objective response rate was similar between the study arms. Median overall survival was 23.7 months and 34.1 months, respectively. Dose reductions and interruptions were more common with sunitinib. Hematologic toxicity was more common in the sunitinib arm. Conclusion While the results of the sunitinib arm are comparable with those of previously reported FOLFOX combinations, the sunitinib-based combination was associated with more toxicity than that observed with bevacizumab and mFOLFOX6. The bevacizumab arm had an unexpectedly good outcome, and was much better than that seen in the Phase III trials. Combination therapy with sunitinib plus mFOLFOX6 is not recommended for patients with metastatic colorectal cancer. PMID:26109878

To investigate the preventive effect of magnesium isoglycyrrhizinate against acute drug-induced liver damage from initial chemotherapy treatment in patients with gastrointestinal cancer. A total of 216 cases with early stage gastric cancer and indications for systemic chemotherapy that had been diagnosed with gastrointestinal malignant tumors by pathology in our hospital were enrolled for study during the period of January 2011 to June 2013.Using a prospective randomized controlled study design,differences were assessed between groups treated with glycyrrhizic acid magnesium (experimental group; n=114) or glutathione (control group; n=102) and the FOLFOX regimen (n=104) or the XELOX regimen (n=112).Patients in the FOLFOX group received intravenous infusion of L-OHP (85 mg/m²) at day 1,followed by a bolus injection of 5-FU (400 mg/m²) at days 1-2 and continuous intravenous infusion of 5-FU (600 mg/m²) for 22 h at days 1-2,with one cycle comprising 2 weeks. Patients in the XELOX group received intravenous infusion of L-OHP (130 mg/m²) at day 1, followed by capecitabine (1 000 mg/m²) oral twice a day at days 1-14,with one cycle comprising 3 weeks.In the first cycle of chemotherapy,serum was extracted from the patients at 1 day before chemotherapy and 1 week after chemotherapy.An automated biochemistry analyzer was used to measure alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) and alkaline phosphatase (ALP). Differences between groups were statistically analyzed by the t-test and x² test. Among the total 216 cases treated with chemotherapy,40 showed hepatic biochemical abnormalities (12 cases in the experimental group, 28 cases in the control group), and the effect of prevention was significantly different between the two groups (10.53% vs. 27.25%; x² =10.219, P less than 0.005).The acute and subacute hepatic toxicity reaction degrees for the experimental and the control groups were: 0:94.78% vs. 88.2%; 1:5.3% vs. 11.8% (x² =6.99, P < 0.01). One week after chemotherapy, the liver biochemical indexes in the experimental group (ALT:35.93 ± 8.33 U/L; AST:24.84 ±2.91 U/L; TBil:13.29 ± 5.89 mumol/L; ALP:125.1 ± 53.61 U/L) were statically different from those in the control group (all P < 0.05). The liver biochemical indexes before and after chemotherapy were also significantly different between the experimental group (ALT:13.18t3.23 U/L; AST:5.39 ± 2.57 U/L; TBil:2.79 ± 0.23 mumol/L; ALP:52.08 ± 4.83 U/L) and the control group (all P < 0.05).One week after chemotherapy in the experimental group, the groups treated with the FOLFOX regimen or the XELOX regimen showed no statistical differences in the liver biochemical indexes.One week after chemotherapy in the control group, though, the groups treated with the FOLFOX regimen showed significantly lower AST (26.24 ± 3.50 U/L vs. 29.80 ± 6.57 U/L, t=-2.431, P < 0.05),but the residual liver biochemical indexes were not significantly different.In the experimental group, the FOLFOX group showed significantly lower ALP (53.44 ± 2.47 U/L vs. 56.58 ± 6.70 U/L, t =-2.201, P < 0.05), AST (6.48 ± 3.15U/L vs. 9.88 ± 4.57 U/L, t =-5.223, P < 0.05), but the residual liver biochemical index was not significantly different. Magnesium isoglycyrrhizinate is an effective drug for the prevention of drug-induced liver damage after initial chemotherapy in patients with early stage gastrointestinal cancer.

Background: NCCN has classified commonly used chemotherapy regimens into high (>20%), intermediate (10%-20%), or low (<10%) febrile neutropenia (FN) risk categories based primarily on clinical trial evidence. Many chemotherapy regimens, however, remain unclassified by NCCN or lack FN incidence data in real-world clinical practice. Patients and Methods: We evaluated incidence proportions of FN and grade 4 and 3/4 neutropenia during the first chemotherapy course among patients from Kaiser Permanente Southern California who received selected chemotherapy regimens without well-established FN risk. Patients given granulocyte colony-stimulating factor (G-CSF) prophylaxis were excluded. Sensitivity analyses were performed to account for FN misclassification and censoring. Results: From 2008 to 2013, 1,312 patients with breast cancer who received docetaxel and cyclophosphamide (TC; n=853) or docetaxel, carboplatin, and trastuzumab (TCH; n=459); 1,321 patients with colorectal cancer who received capecitabine and oxaliplatin (XELOX; n=401) or leucovorin, 5-fluorouracil, and oxaliplatin (FOLFOX6; n=920); 307 patients with non-Hodgkin's lymphoma who received bendamustine with or without rituximab; and 181 patients with multiple myeloma who received lenalidomide with or without dexamethasone were included. Crude FN risk was >20% for both breast cancer regimens (TC and TCH). Crude FN risks for XELOX, FOLFOX6, bendamustine, and lenalidomide were <10%; however, when potential FN misclassification and censoring were considered, FN risks were >10%. Conclusions: Our results support published literature highlighting the real-world, "high" FN risk of the TC and TCH regimens for breast cancer. There is strong suggestive evidence that FN risks for XELOX, FOLFOX6, bendamustine, and lenalidomide are >10%. Calculation of chemotherapy course-level FN incidence without controlling for differential censoring for patients who discontinued regimens early, or possible FN misclassification, might have resulted in bias toward an underestimation of the true FN risk. These findings help define FN risk of the selected regimens in the real-world setting and inform prophylactic G-CSF use. Copyright © 2017 by the National Comprehensive Cancer Network.

Until now, no standard chemotherapy has been widely accepted for advanced gastric cancer (GC). The current research aimed to compare folinic acid, fluorouracil with irinotecan (mFOLFIRI) or with oxaliplatin (mFOLFOX7) as first-line treatments in patients with locally advanced GC in an open, randomized, phase II study. Previously untreated metastatic or recurrent GC patients with measurable disease received mFOLFIRI (arm A) or mFOLFOX7 (arm B) every 2 weeks. The defined second-line treatment was mFOLFOX7 for arm A and mFOLFIRI for arm B. Primary endpoint was progression-free survival (PFS), and secondary endpoints were overall survival (OS), disease control rate (DCR) and toxicity. The evaluable population consisted of 128 patients (54 in arm A; 74 in arm B). Median PFS of arm A was 2.9 months (m) (95% confidence interval, CI, 1.9 to 4.1 m) versus 4.1 m (95% CI, 3.2 to 4.8 m) for arm B (p = 0.109). Median OS was 9.9 months (95% CI, 6.0 to 13.5 m) for arm A versus 12.0 m for arm B (95% CI, 10.3 to 13.7m; p = 0.431). DCRs for arm A and arm B were 59.3% and 66.3%, respectively (p = 0.850). In subgroup analysis of the patients who completed both treatment lines per protocol, the median first-line PFS was 2.1 m for the mFOLFIRI/mFOLFOX7arm versus 8.0 m for the mFOLFOX7/mFOLFIRI arm (p = 0.053), and the median second-line PFS values were 1.2 m versus 5.1 m (p = 0.287). Total PFS and OS were 8.1m and 11.0 m for the mFOLFIRI/mFOLFOX7 group compared with 12.2m and 20.2 m for the mFOLFOX7/mFOLFIRI group (p = 0.008, p = 0.030). Both regimens were well-tolerated with acceptable and manageable toxicities. Hence, there was no significant difference in the PFS or DCR. However, mFOLFOX7 followed by mFOLFIRI might have a better OS. PMID:29228659

Combination therapies with cetuximab (Erbitux ® ; Merck Serono UK Ltd) and panitumumab (Vectibix ® ; Amgen UK Ltd) are shown to be less effective in adults with metastatic colorectal cancer who have mutations in exons 2, 3 and 4 of KRAS and NRAS oncogenes from the rat sarcoma (RAS) family. The objective of the study was to estimate the cost effectiveness of these drugs in patients with previously untreated RAS wild-type (i.e. non-mutated) metastatic colorectal cancer, not eligible for liver resection at baseline, from the UK National Health Service and Personal Social Services perspective. We constructed a partitioned survival model to evaluate the long-term costs and benefits of cetuximab and panitumumab combined with either FOLFOX (folinic acid, fluorouracil and oxaliplatin) or FOLFIRI (folinic acid, fluorouracil and irinotecan) vs. FOLFOX or FOLFIRI alone. The economic analysis was based on three randomised controlled trials. Costs and quality-adjusted life-years were discounted at 3.5% per annum. Based on the evidence available, both drugs fulfil the National Institute for Health and Care Excellence's end-of-life criteria. In the analysis, assuming discount prices for the drugs from patient access schemes agreed by the drug manufacturers with the Department of Health, predicted mean incremental cost-effectiveness ratios for cetuximab + FOLFOX, panitumumab + FOLFOX and cetuximab + FOLFIRI compared with chemotherapy alone appeared cost-effective at the National Institute for Health and Care Excellence's threshold of £50,000 per quality-adjusted life-year gained, applicable to end-of-life treatments. Cetuximab and panitumumab were recommended by the National Institute for Health and Care Excellence for patients with previously untreated RAS wild-type metastatic colorectal cancer, not eligible for liver resection at baseline, for use within the National Health Service in England. Both treatments are available via the UK Cancer Drugs Fund.

In Thailand, there has been no economic evaluation study of adjuvant chemotherapy for stage III colon cancer patients after resection. This study aims to evaluate the cost-utility of all chemotherapy regimens currently used in Thailand compared with the adjuvant 5-fluorouracil/leucovorin (5-FU/LV) plus capecitabine as the first-line therapy for metastatic disease in patients with stage III colon cancer after resection. A cost-utility analysis was performed to estimate the relevant lifetime costs and health outcomes of chemotherapy regimens based on a societal perspective using a Markov model. The results suggested that the adjuvant 5-FU/LV plus capecitabine as the first-line therapy for metastatic disease would be the most cost-effective chemotherapy. The adjuvant FOLFOX and FOLFIRI as the first-line treatment for metastatic disease would be cost-effective with an incremental cost-effectiveness ratio of 299,365 Thai baht per QALY gained based on a societal perspective if both prices of FOLFOX and FOLFIRI were decreased by 40%.

The cost of chemotherapy has dramatically increased in advanced colorectal cancer patients, and the schedule of fluorouracil administration appears to be a determining factor. This retrospective study compared direct medical costs related to two different de Gramont schedules (standard vs. simplified) given in first-line chemotherapy with oxaliplatin or irinotecan. This cost-minimization analysis was performed from the French Health System perspective. Consecutive unselected patients treated in first-line therapy by LV5FU2 de Gramont with oxaliplatin (Folfox regimen) or with irinotecan (Folfiri regimen) were enrolled. Hospital and outpatient resources related to chemotherapy and adverse events were collected from 1999 to 2004 in 87 patients. Overall cost was reduced in the simplified regimen. The major factor which explained cost saving was the lower need for admissions for chemotherapy. Amount of cost saving depended on the method for assessing hospital stay. In patients treated by the Folfox regimen the per diem and DRG methods found cost savings of Euro 1,997 and Euro 5,982 according to studied schedules; in patients treated by Folfiri regimen cost savings of Euro 4,773 and Euro 7,274 were observed, respectively. In addition, travel costs were also reduced by simplified regimens. The robustness of our results was showed by one-way sensitivity analyses. These findings demonstrate that the simplified de Gramont schedule reduces costs of current first-line chemotherapy in advanced colorectal cancer. Interestingly, our study showed several differences in costs between two costing approaches of hospital stay: average per diem and DRG costs. These results suggested that standard regimen may be considered a profitable strategy from the hospital perspective. The opposition between health system perspective and hospital perspective is worth examining and may affect daily practices. In conclusion, our study shows that the simplified de Gramont schedule in combination with oxaliplatin or irinotecan is an attractive option from the French Health System perspective. This safe and less costly regimen must compared to alternative options such as oral fluoropyrimidines.

EOX (epirubicin, oxaliplatin, Xeloda; capecitabine) and FOLFOX4 (5-fluorouracil (5-FU), leucovorin, oxaliplatin) are the common chemotherapy regimens used in the treatment of advanced gastric cancer (aGC) in Hong Kong. This study aimed to compare the costs of these therapies for aGC patients from both the healthcare and societal perspectives. It should be noted that, while FOLFOX4 is routinely administered in an outpatient setting in North America and Europe, inpatient setting is adopted in Hong Kong instead, incurring hospitalization cost as a result. Fifty-eight patients were identified from the electronic records in two public tertiary hospitals, with 45 and 13 receiving EOX and FOLFOX4 regimens, respectively. Healthcare cost was direct medical costs including drugs, clinic follow-up, hospitalization, diagnostic laboratories, and radiographs. Societal cost refers to indirect costs such as patient time and travel costs. Cost items were further classified as "expected" or "unexpected". All cost data was expressed in US dollars. Patients in the EOX and FOLFOX4 arm received an average of 5.3 and 7.8 cycles of treatment, respectively. The capecitabine-based regimen group had a higher expected medication cost per cycle when compared to the 5-FU-based treatment group (US$290.3 vs US$66.9, p < .001), but lower expected hospitalization costs (US$76.9 vs US$1,269.2, p < .001). The total healthcare cost and total societal cost per patient was reduced by 67.2% (US$5,691.9 vs US$17,357.4, p < .001) and 25.3% (US$3,090.5 vs US$4,135.1, p = .001), respectively, in the capecitabine-based regimen group. Sensitivity analyses based on full cycle regimen costs and net capecitabine or 5-FU/leucovorin costs still showed EOX to be less costly than FOLFOX4. The capecitabine-based regimen, EOX, was found to generate significant cost saving from both the healthcare and societal perspectives in regions in which FOLFOX4 is given in an inpatient setting.

Chemotherapy drugs, including 5-fluorouracil (5-FU), oxaliplatin and docetaxel, are commonly used in the treatment of gastric cancer (GC). Apoptosis-relevant genes may be associated with drug resistance. In the present study, the messenger RNA (mRNA) expression levels of B-cell lymphoma 2 interacting mediator of cell death (BIM), astrocyte elevated gene-1 (AEG-1) and AXL receptor tyrosine kinase (AXL) were investigated in 131 advanced GC samples, and the expression levels of these genes were correlated with patients' overall survival (OS). All 131 patients received first-line FOLFOX combination chemotherapy with folinic acid and 5-FU, in which 56 patients were further treated with second-line docetaxel-based chemotherapy. A correlation between the mRNA expression levels of BIM and AEG-1 was observed ( r s =0.30; P=0.002). There was no association between the mRNA expression levels of any of the individual genes analyzed and OS in patients only receiving first-line FOLFOX chemotherapy. In a subgroup of patients receiving docetaxel-based second-line chemotherapy, those with high or intermediate levels of BIM exhibited a median OS of 18.2 months [95% confidence interval (CI), 12.8-23.6], compared with 9.6 months (95% CI, 8.9-10.3) in patients with low BIM levels (P=0.008). However, there was no correlation between the mRNA expression levels of AEG-1 or AXL and OS. The risk of mortality was higher in patients with low BIM mRNA levels than in those with high or intermediate BIM mRNA levels (hazard ratio, 2.61; 95% CI, 1.21-5.62; P=0.010). Therefore, BIM may be considered as a biomarker to identify whether patients could benefit from docetaxel-based second-line chemotherapy in GC.

Polymorphisms in drug-metabolizing enzymes might not completely explain inter-individual differences in toxicity profiles of patients with colorectal cancer (CRC) that receive folinic acid/5-fluorouracil/oxaliplatin (FOLFOX4). Recent data indicate that the immune system could contribute to FOLFOX4 outcomes. In light of the immune inhibitory nature of human leukocyte antigen-G (HLA-G), a non-classical major histocompatibility complex (MHC) class I molecule, we aimed to identify novel genomic markers of grades 3 and 4 (G3-4) toxicity related to FOLFOX4 therapy in patients with CRC. We retrospectively analyzed data for 144 patients with stages II-III CRC to identify HLA-G 3′ untranslated region (3′UTR) polymorphisms and related haplotypes and evaluate their impact on the risk of developing G3-4 toxicities (i.e., neutropenia, hematological/non-hematological toxicity, neurotoxicity) with logistic regression. The rs1610696-G/G polymorphism was associated with increased risk of G3-4 neutropenia (OR = 3.76, p = 0.015) and neurotoxicity (OR = 8.78, p = 0.016); rs371194629-Ins/Ins was associated with increased risk of neurotoxicity (OR = 5.49, p = 0.027). HLA-G 3′UTR-2, which contains rs1610696-G/G and rs371194629-Ins/Ins polymorphisms, was associated with increased risk of G3-4 neutropenia (OR = 3.92, p = 0.017) and neurotoxicity (OR = 11.29, p = 0.009). A bootstrap analysis confirmed the predictive value of rs1610696 and rs371194629, but the UTR-2 haplotype was validated only for neurotoxicity. This exploratory study identified new HLA-G 3′UTR polymorphisms/haplotypes as potential predictive markers of G3-4 toxicities in CRC. PMID:28653974

Cetuximab combined with chemotherapy is one of the first-line treatments of metastatic colorectal cancer. Although disease progression inevitably occurs, rechallenge and maintenance therapies using cetuximab-based regimens may be beneficial, particularly for patients with wild-type (WT) KRAS. A 47-year-old female patient who underwent right hemicolectomy presented with an ulcerative adenocarcinoma (grade 2) revealed by histopathological analysis. The patient received three cycles of adjuvant chemotherapy, but disease recurred 15 months later. Cetuximab and a FOLFOX-4 regimen were administered, followed by surgery and adjuvant chemotherapy that was administered for approximately one year. Three years after completing adjuvant therapy, her serum carcinoembryonic antigen levels rapidly increased, and enhanced computed tomography showed widespread metastases. Rechallenge with cetuximab and the FOLFIRI regimen was then initiated, and after 12 cycles, lesions in the lung and liver shrank significantly, and serum CEA levels dramatically declined. Maintenance therapy with cetuximab and capecitabine was then administered for 10 months until the metastatic lesions in the lung and liver enlarged. Rechallenge and maintenance therapy with cetuximab-based chemotherapy were relatively effective for managing a female patient with WT KRAS. Optimization of this strategy requires further in-depth investigations of more patients.

Background Preoperative radiation therapy with 5-fluorouracil chemotherapy is a standard of care for cT3-4 rectal cancer. Studies incorporating additional cytotoxic agents demonstrate increased morbidity with little benefit. We evaluate a template that: (1) includes the benefits of preoperative radiation therapy on local response/control; (2) provides preoperative multidrug chemotherapy; and (3) avoids the morbidity of concurrent radiation therapy and multidrug chemotherapy. Methods and Materials Patients with cT3-4, any N, any M rectal cancer were eligible. Patients were confirmed to be candidates for pelvic surgery, provided response was sufficient. Preoperative treatment was 5 fractions radiation therapy (25 Gy to involved mesorectum, 20 Gy to elective nodes), followed by 4 cycles of FOLFOX [5-fluorouracil, oxaliplatin, leucovorin]. Extirpative surgery was performed 4 to 9 weeks after preoperative chemotherapy. Postoperative chemotherapy was at the discretion of the medical oncologist. The principal objectives were to achieve T stage downstaging (ypT < cT) and preoperative grade 3+ gastrointestinal morbidity equal to or better than that of historical controls. Results 76 evaluable cases included 7 cT4 and 69 cT3; 59 (78%) cN+, and 7 cM1. Grade 3 preoperative GI morbidity occurred in 7 cases (9%) (no grade 4 or 5). Sphincter-preserving surgery was performed on 57 (75%) patients. At surgery, 53 patients (70%) had ypT0-2 residual disease, including 21 (28%) ypT0 and 19 (25%) ypT0N0 (complete response); 24 (32%) were ypN+. At 30 months, local control for all evaluable cases and freedom from disease for M0 evaluable cases were, respectively, 95% (95% confidence interval [CI]: 89%–100%) and 87% (95% CI: 76%–98%). Cases were subanalyzed by whether disease met requirements for the recently activated PROSPECT trial for intermediate-risk rectal cancer. Thirty-eight patients met PROSPECT eligibility and achieved 16 ypT0 (42%), 15 ypT0N0 (39%), and 33 ypT0-2 (87%).

A-64-years-old woman with locally advanced rectal cancer, which had invaded the vagina, was referred to our hospital. She was administered neoadjuvant chemotherapy to reduce the tumor size. After 4 courses of chemotherapy consisting of folinic acid, fluorouracil, and oxaliplatin (mFOLFOX6), an enhanced computed tomography (CT) scan and magnetic resonance imaging (MRI) indicated marked tumor shrinkage. We performed a laparoscopically assisted low anterior resection, which included total mesorectal resection, resection of the vaginal posterior wall, and right lateral lymph node resection. The chemotherapy prevented us from having to create a permanent colostomy. The efficacy of the neoadjuvant chemotherapy was Grade 1b. We experienced a case of neoadjuvant chemotherapy followed by curative resection.

To assess nonfeasibility of adjuvant-modified FOLFOX6 chemotherapy in patients with stage II or III colorectal cancer. Consecutive patients managed between 2009 and 2013 in 2 teaching hospitals in the Paris urban area were included in the CORSAGE (COlorectal canceR, AGe, and chemotherapy fEasability study) cohort study. Nonfeasibility was defined by the frequencies of empirical first-cycle dose reduction (>15%), early discontinuation (<12 cycles), and low relative dose intensity (RDI) (<0.85). Risk factors for chemotherapy nonfeasibility were identified using multivariate logistic regression. Among 153 patients, 56.2% were male (median age, 65.6 y; 35.3%≥70 y; 7.3% with performance status [PS]≥2). For 5-fluorouracil (5-FU), 20.9% of patients had first-cycle dose reduction and 28.1% early discontinuation; RDI was 0.91 (25th to 75th percentiles, 0.68 to 0.99). Factors independently associated with first-cycle 5-FU dose reduction were aged 65 to 69 years versus those younger than 65 years (adjusted odds ratio [aOR], 5.5; 95% confidence interval [CI], 1.5-19.9) but not age 70 years and older, PS≥2 (aOR, 6.02; 95% CI, 1.15-31.4), higher Charlson Comorbidity Index (aOR1-point increase, 1.4; 95% CI, 1.05-1.82), or larger number of medications (aOR 1-medication increase, 1.19; 95% CI, 1.00-1.42). Oxaliplatin dose reduction occurred in 52.3% of patients and early discontinuation in 62.7%; the latter was more common in the 70 years and older group (92.6% vs. 74.6% in the <65-y group; P=0.01); RDI was 0.7 (95% CI, 0.55-0.88). In the real-world setting, compared with their younger and older counterparts, patients aged 65 to 69 years given modified FOLFOX6 for stage II or III colorectal cancer had higher frequencies of 5-FU nonfeasibility defined based on first-cycle dose reduction, early discontinuation, and RDI; and these differences were independent from PS, comorbidities, and number of medications.

The authors hypothesized that patients with metastatic colorectal cancer (mCRC) who had tumors with low thymidylate synthase (TS-L) expression would have a higher response rate to combined 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) plus bevacizumab (FOLFOX/Bev) than those with high TS (TS-H) expression and that combined irinotecan and oxaliplatin (IROX) plus bevacizumab (IROX/Bev) would be more effective than FOLFOX/Bev in those with TS-H tumors. TS protein expression was determined in mCRC tissue. Patients who had TS-L tumors received FOLFOX/Bev, and those who had TS-H tumors were randomly assigned to receive either FOLFOX/Bev or IROX/Bev. The primary endpoint was the response rate (complete plus partial responses). In total, 211 of 247 patients (70% TS-H) were registered to the treatment phase. Efficacy analyses included eligible patients who had started treatment (N = 186). The response rates for patients who received IROX/Bev (TS-H), FOLFOX/Bev (TS-H), and FOLFOX/Bev (TS-L) were 33%, 38%, and 49%, respectively (P = nonsignificant). The median progression-free survival (PFS) was 10 months (95% confidence interval [CI], 9-12 months; 10 months in the IROX/Bev TS-H group, 9 months in the FOLFOX/Bev TS-H group, and 13 months in the FOLFOX/Bev TS-L group). The TS-L group had improved PFS compared with the TS-H group that received FOLFOX/Bev (hazard ratio, 1.6; 95% CI, 1.0%-2.4%; P = .04; Cox regression). The median overall survival (OS) was 22 months (95% CI, 20 29 months; 18 months in the IROX/Bev TS-H group, 21 months in the FOLFOX/Bev TS-H group, and 32 months in the TS-L group). OS comparisons for the 2 TS-H arms and for the FOLFOX/Bev TS-H versus TS-L arms were not significantly different. TS expression was prognostic: Patients with TS-L tumors who received FOLFOX/Bev had a longer PFS than those with TS-H tumors, along with a trend toward longer OS. Patients with TS-H tumors did not benefit more from IROX/Bev than from FOLFOX/Bev. Cancer 2018;124:688-97. © 2017 American Cancer Society. © 2017 American Cancer Society.

Background Methylation levels of long interspersed nucleotide elements (LINE-1) are representative of genome-wide methylation status and crucial in maintaining genomic stability and expression. Their prognostic impact on colon cancer patients receiving adjuvant chemotherapy has not been well established. We evaluated the association between LINE-1 methylation status and clinicopathologic features and postoperative oncological outcomes in stage III colon cancer patients. Materials and Methods 129 UICC stage III colon cancer patients who had received radical resection and FOLFOX adjuvant chemotherapy were enrolled. Global methylation was estimated by analyzing tumor LINE-1 methylation status using bisulfite-polymerase chain reaction (PCR) and pyrosequencing assay. Demographics, clinicopathological data, and postoperative outcomes were recorded by trained abstractors. Outcome measurements included postoperative recurrence and disease-free survival. Univariate, multivariate, and survival analyses were conducted to identify prognostic factors of oncological outcomes. Results The LINE-1 methylation of all 129 patients was measured on a 0–100 scale (mean 63.3; median 63.7, standard deviation 7.1), LINE-1 hypomethylation was more common in patients aged 65 years and above (61.7%±7.6% vs. 64.6±6.4, p=0.019) and those with post-therapeutic recurrence (61.7±7.4 vs 64.3±6.7, p=0.041). Considering risk adjustment, LINE-1 hypomethylation was found to be an independent risk factor of post-therapeutic recurrence (Adjusted OR=14.1, p=0.012). Kaplan-Meier analysis indicated that patients in the low methylation group had shorter period of disease free survival (p=0.01). In a stratified analysis that included 48 patients with post-therapeutic recurrence, it was found that those who experienced shorter period of disease free survival (≦6 months) appeared to have lower LINE-1 methylation levels than patients who reported of recurrence after 6 months (56.68±15.75 vs. 63.55±7.57, p=0.041) Conclusion There was a significantly greater risk of early postoperative recurrence and a shorter period of disease-free survival in Stage III colon cancer patients exhibiting LINE-1 hypomethylation status after being treated with radical resection and FOLFOX chemotherapy.

Six months of oxaliplatin-based adjuvant chemotherapy is standard of care for radically resected stage III colon cancer and an accepted option for high-risk stage II. A shorter duration of therapy, if equally efficacious, would be advantageous for patients and Health-Care Systems. TOSCA ['Randomized trial investigating the role of FOLFOX-4 or XELOX (3 versus 6 months) regimen duration and bevacizumab as adjuvant therapy for patients with stage II/III colon cancer] is an open-label, phase III, multicenter, noninferiority trial randomizing patients with high-risk stage II or stage III radically resected colon cancer to receive 3 months (arm 3 m) versus 6 months (arm 6 m) of FOLFOX4/XELOX. Primary end-point was relapse-free survival. We present here safety and compliance data. From June 2007 to March 2013, 3759 patients were accrued from 130 Italian sites, 64% receiving FOLFOX4 and 36% XELOX in either arm. Treatment completion rate without any modification was 35% versus 12% and with delays or dose reduction 52% versus 44% in arm 3 and 6 m. Treatment was permanently discontinued in 8% (arm 3 m) and 33% (arm 6 m). In arm 6 m, 50% of patients discontinuing treatment did so after completing 80% of planned program. Grade 3+ toxicities were higher in arm 6 m than that in 3 m. Grade 2+ neuropathy was 31.2% versus 8.8% (P < 0.0001) while grade 3+ was 8.4 versus 1.3 (P < 0.0001), in arm 3 and 6 m. Seven deaths within 30 days from last treatment administration in arm 6 m and three deaths in arm 3 m were observed (0.3% versus 0.1%, P = 0.34). TOSCA is the first trial comparing 3 versus 6 months of adjuvant chemotherapy completing accrual within the international initiative of treatment duration evaluation (International Duration Evaluation of Adjuvant, IDEA). High compliance to treatment in control arm will allow a correct assessment of potential differences between the two treatment durations. NCT00646607. © The Author 2016.

Fast track multi-discipline treatment (FTMDT trial) versus conventional treatment in colorectal cancer--the design of a prospective randomized controlled study

PubMed Central

2011-01-01

Background Laparoscopy-assisted surgery, fast-track perioperative treatment are both increasingly used in colorectal cancer treatment, for their short-time benefits of enhanced recovery and short hospital stays. However, the benefits of the integration of the Laparoscopy-assisted surgery, fast-track perioperative treatment, and even with the Xelox chemotherapy, are still unknown. In this study, the three treatments integration is defined as "Fast Track Multi-Discipline Treatment Model" for colorectal cancer and this model extends the benefits to the whole treatment process of colorectal cancer. The main purpose of the study is to explore the feasibility of "Fast Track Multi-Discipline Treatment" model in treatment of colorectal cancer. Methods The trial is a prospective randomized controlled study with 2 × 2 balanced factorial design. Patients eligible for the study will be randomized to 4 groups: (I) Laparoscopic surgery with fast track perioperative treatment and Xelox chemotherapy; (II) Open surgery with fast track perioperative treatment and Xelox chemotherapy; (III) Laparoscopic surgery with conventional perioperative treatment and mFolfox6 chemotherapy; (IV) Open surgery with conventional perioperative treatment and mFolfox6 chemotherapy. The primary endpoint of this study is the hospital stays. The secondary endpoints are the quality of life, chemotherapy related adverse events, surgical complications and hospitalization costs. Totally, 340 patients will be enrolled with 85 patients in each group. Conclusions The study initiates a new treatment model "Fast Track Multi-Discipline Treatment" for colorectal cancer, and will provide feasibility evidence on the new model "Fast Track Multi-Discipline Treatment" for patients with colorectal cancer.

A 77-year-old woman with rectal cancer and synchronous liver metastasis underwent a Hartmann operation with D3 lymph node dissection in June 2014. mFOLFOX6 plus bevacizumab(bev)was then administered to treat the liver metastasis.In February 2015, multiple liver metastases were detected and the regimen was changed to FOLFIRI plus bev.After 3 courses, peritonitis due to intestinal perforation around the descending colostomy occurred, and an emergency operation(partial resection of the descending colon and transverse colostomy)was performed.FOLFIRI was then administered from 2 months after the operation.After 3 courses of this regimen, a CT scan showed progression of the hepatic metastases.The regimen was therefore changed to mFOLFOX6.Five months later, another CT scan showed an intestinal perforation of the transverse colostomy at the abdominal wall, and an emergency cecostomy was performed.At this stage, chemotherapy was ceased.This case highlights the risk of intestinal perforation during chemotherapy, regardless of the use of bev.

Purpose Given that the clinical course of oxaliplatin-induced neuropathy is not well defined, the current study was performed to better understand clinical parameters associated with its presentation. Methods Acute and chronic neuropathy was evaluated in patients receiving adjuvant FOLFOX (fluorouracil, leucovorin, and oxaliplatin) on study N08CB (North Central Cancer Treatment Group, Alliance). Acute neuropathy was assessed by having patients complete daily questionnaires for 6 days with each cycle of FOLFOX. Before each dose of FOLFOX and as long as 18 months after chemotherapy cessation, chronic neurotoxicity was assessed with use of the 20-item, European Organisation for Research and Treatment of Cancer quality-of-life questionnaire for patients with chemotherapy-induced peripheral neuropathy. Results Three hundred eight (89%) of the 346 patients had at least one symptom of acute neuropathy with the first cycle of FOLFOX; these symptoms included sensitivity to touching cold items (71%), sensitivity to swallowing cold items (71%), throat discomfort (63%), or muscle cramps (42%). Acute symptoms peaked at day 3 and improved, although they did not always resolve completely between treatments. These symptoms were about twice as severe in cycles 2 through 12 as they were in cycle 1. For chronic neurotoxicity, tingling was the most severe symptom, followed by numbness and then pain. During chemotherapy, symptoms in the hands were more prominent than they were in the feet; by 18 months, symptoms were more severe in the feet than they were in the hands. Patients with more severe acute neuropathy during the first cycle of therapy experienced more chronic sensory neurotoxicity (P < .0001). Conclusion Acute oxaliplatin-induced neuropathy symptoms do not always completely resolve between treatment cycles and are only half as severe on the first cycle as compared with subsequent cycles. There is a correlation between the severities of acute and chronic neuropathies. PMID:26282635

To compare the costs of first-line treatment with panitumumab + FOLFOX in comparison to cetuximab + FOLFIRI among patients with wild-type (WT) RAS metastatic colorectal cancer (mCRC) in the US. A cost-minimization model was developed assuming similar treatment efficacy between both regimens. The model estimated the costs associated with drug acquisition, treatment administration frequency (every 2 weeks for panitumumab, weekly for cetuximab), and incidence of infusion reactions. Average anti-EGFR doses were calculated from the ASPECCT clinical trial, and average doses of chemotherapy regimens were based on product labels. Using the medical component of the consumer price index, adverse event costs were inflated to 2014 US dollars, and all other costs were reported in 2014 US dollars. The time horizon for the model was based on average first-line progression-free survival of a WT RAS patient, estimated from parametric survival analyses of PRIME clinical trial data. Relative to cetuximab + FOLFIRI in the first-line treatment of WT RAS mCRC, the cost-minimization model demonstrated lower projected drug acquisition, administration, and adverse event costs for patients who received panitumumab + FOLFOX. The overall cost per patient for first-line treatment was $179,219 for panitumumab + FOLFOX vs $202,344 for cetuximab + FOLFIRI, resulting in a per-patient saving of $23,125 (11.4%) in favor of panitumumab + FOLFOX. From a value perspective, the cost-minimization model supports panitumumab + FOLFOX instead of cetuximab + FOLFIRI as the preferred first-line treatment of WT RAS mCRC patients requiring systemic therapy.

We report a female case of sinusoidal obstruction syndrome (SOS) diagnosed pathologically after chemotherapy (Pmab+m-FOLFOX6) for ascending colon cancer with multiple liver metastases, focusing on the findings of gadoxetic acid-enhanced MRI (EOB-MRI) and the organic anion transporting polypeptide 1B3 (OATP1B3) expression of in the liver. The patient was a 75-year-old female. She had received chemotherapy (Pmab+m-FOLFOX6) as six cycles for preoperative chemotherapy. After the preoperative chemotherapy, tumor sizes of hepatic metastases were reduced and hepatobiliary phase of EOB-MRI clearly depicted diffuse reticular hypointensity in the background liver. On the other hand, dynamic CT and/or other sequences of EOB-MRI did not show definite abnormality in the background liver. After the operation, this patient was pathologically confirmed as SOS demonstrating centrilobular congestion, sinusoidal dilatation, and perisinusoidal fibrosis. In normal liver parenchyma, OATP1B3 (uptake transporter of the EOB-MRI) expression is observed predominantly in centrilobular hepatocytes (zone 3). On the other hand, OATP1B3 expression was remarkably reduced because of the damages in the centrilobular (zone 3) hepatocytes in this SOS case. This indicated that EOB-MRI might be extremely sensitive in diagnosing SOS in its early stage.

Few data are available regarding the treatment of metastatic colorectal cancer elderly patients with anti-EGFR agents in combination with chemotherapy. FOLFOX plus panitumumab is a standard first-line option for RAS wild-type metastatic colorectal cancer. Slight adjustments in chemo-dosage are commonly applied in clinical practice to elderly patients, but those modified schedules have never been prospectively tested. Clinical definition of elderly (≥70 years old) patients that may deserve a more or less intensive combination therapy is still debated. Several geriatric screening tools have been developed to predict survival and risk of toxicity from treatment. Among those, the G8 screening tool has been tested in cancer patients showing the strongest prognostic value for overall survival, while the CRASH score can stratify patients according to an estimated risk of treatment-related toxicities. The PANDA study is a prospective, open-label, multicenter, randomized phase II trial of first-line therapy with panitumumab in combination with dose-adjusted FOLFOX or with 5-fluorouracil monotherapy, in previously untreated elderly patients (≥70 years) with RAS and BRAF wild-type unresectable metastatic colorectal cancer. RAS and BRAF analyses are centralized. Geriatric assessment by means of G8 and CRASH score is planned at baseline and G8 will be re-evaluated at disease progression. The primary endpoint is duration of progression-free survival in both arms. Secondary endpoints include prospective evaluation of the prognostic role of G8 score and the correlation of CRASH risk categories with toxicity. The PANDA study aims at exploring safety and efficacy of panitumumab in combination with FOLFOX or with 5FU/LV in elderly patients affected by RAS and BRAF wild-type metastatic colorectal cancer, to identify the most promising treatment strategy in this setting.

In practice, small bowel cancer is a rare entity. The most common histologic subtype is adenocarcinoma. Adenocarcinoma of the small bowel (SBA) is challenging to diagnose, often presents at a late stage and has a poor prognosis. The treatment of early-stage SBA is surgical resection. No standard protocol has been established for unresectable or metastatic disease. We report here on a 26-year-old man with SBA in the jejunum, lacking specific symptoms and with a delay of 6 months in diagnosis. The diagnosis was finally achieved with a combination of balloon-assisted enteroscopy, computed tomography scans, positron emission computed tomography scans and the values of carcino-embryonic antigen and carbohydrate antigen 19-9. The patient underwent segmental intestine with lymph node resection, followed by eight cycles of FOLFOX palliative chemotherapy with good tolerance. As of the 11-month postoperative follow-up, there has been no evidence of recurrent disease. This case is reported to arouse a clinical suspicion of SBA in patients with abdominal pain of unknown cause. We also provided evidence in this case of a response to palliative chemotherapy with FOLFOX. Because the incidence of SBA is very low, there is a need for further studies to evaluate the possible application of newer investigative agents and strategies to obtain a better outcome within the framework of international collaborations.

The patient was a 73-year-old female. After curative resection for rectal cancer with uterus invasion, UFT/Leucovorin was administered orally for 16 months. Three years and six months after the initial surgery, en bloc cystourethrectomy was performed to control the bleeding caused by a local recurrence invading the bladder and ureter. Although postoperative FOL- FOX4/bevacizumab therapy was started, bevacizumab was discontinued after 4 courses of treatment because an ulcer was confirmed at the sigmoid colon with stoma. The ulcer was relieved by conservative medical treatment. In this case, we attempted to make a quick response because the site of the ulcer could be easily observed. During chemotherapy. Therefore, it is necessary to carefully observe the patient's conditions.

A 55-year-old woman underwent laparoscopic anterior resection and D2 lymph node dissection for recto-sigmoid colon cancer in November 2014, which was diagnosed as T3N1M1(H3, PUL2), stage IV , for the purpose of preserving the ileus. FOLFOX therapy with panitumumab(Pmab)was started in January 2015.A t the end of 11 courses, pulmonary metastasis changed to CR, and liver metastasis was down-graded to H2 on the CT.Because of the risk of hepatic dysfunction with advanced fatty liver due to chemotherapy and extrahepatic lesions, we chose radiofrequency ablation(RFA)therapy for liver metastasis.Pmab combined FOLFIRI therapy was administered, and maintenance therapy was initiated.This patient is alive 2 years and 7 months after surgery and 10 months after RFA without relapse.It is suggested that RFA therapy for liver metastasis of colon cancer with pulmonary metastasis combined with chemotherapy could be an effective treatment strategy.

To compare the overall survival (OS) and disease progression free survival (PFS) in patients with advanced hepatocellular carcinoma (Ad-HCC) who are undergoing hepatic arterial infusion (HAI) of oxaliplatin, fluorouracil/leucovorin (FOLFOX) treatment vs. sorafenib. This retrospective study was approved by the ethical review committee, and informed consent was obtained from all patients before treatment. HAI of FOLFOX (HAIF) was recommended as an alternative treatment option for patients who refused sorafenib. Of the 412 patients with Ad-HCC (376 men and 36 women) between Jan 2012 to Dec 2015, 232 patients were treated with sorafenib; 180 patients were given HAIF therapy. The median age was 51 years (range, 16-82 years). Propensity-score matched estimates were used to reduce bias when evaluating survival. Survival curves were calculated by performing the Kaplan-Meier method and compared by using the log-rank test and Cox regression models. The median PFS and OS in the HAIF group were significantly longer than those in the sorafenib group (PFS 7.1 vs. 3.3 months [RECIST]/7.4 vs. 3.6 months [mRECIST], respectively; OS 14.5 vs. 7.0 months; p <0.001 for each). In the propensity-score matched cohorts (147 pairs), both PFS and OS in the HAIF group were longer than those in the sorafenib group (p <0.001). At multivariate analysis, HAIF treatment was an independent factor for PFS (hazard ratio [HR] 0.389 [RECIST]/0.402 [mRECIST]; p <0.001 for each) and OS (HR 0.129; p <0.001). HAIF therapy may improve survival compared to sorafenib in patients with Ad-HCC. A prospective randomized trial is ongoing to confirm this finding. We compared the hepatic arterial infusion of FOLFOX (a combination chemotherapy) with sorafenib (a tyrosine kinase inhibitor) in patients with advanced hepatocellular carcinoma, retrospectively. It was found that hepatic arterial infusion of FOLFOX therapy may improve both progression free and overall survival in patients with advanced hepatocellular carcinoma.

Primary tumor location is a critical prognostic factor in metastatic colorectal cancer (mCRC); however, it remains unclear whether tumor location is a predictor of the response to cetuximab treatment. It is also uncertain if BRAF mutation contributes to the impact of tumor location on survival. We assessed the prognostic impact of tumor location on clinical outcomes in mCRC patients treated with first-line cetuximab chemotherapy. The associations of tumor location with overall survival and progression-free survival were evaluated in mCRC patients with KRAS exon 2 wild-type tumors who were enrolled onto 2 clinical trials: JACCRO CC-05 of cetuximab plus FOLFOX (n = 57, UMIN000004197) and CC-06 of cetuximab plus SOX (n = 61, UMIN000007022). Tumors proximal or from splenic flexure to rectum were defined as right-sided or left-sided, respectively. In addition, exploratory RAS and BRAF mutation analyses were performed. A total of 110 patients were assessable for tumor location; 90 had left-sided tumors. Left-sided tumors were significantly associated with longer overall survival (36.2 vs. 12.6 months, hazard ratio = 0.28, P < .0001) and progression-free survival (11.1 vs. 5.6 months, hazard ratio = 0.47, P = .0041) than right-sided tumors; similar results were obtained in multivariate analysis. A subanalysis showed that the association was evident in the FOLFOX group and that tumor location was an independent prognostic factor irrespective of BRAF status in RAS wild-type patients. Primary tumor location might be a predictor of survival independent of BRAF status in mCRC patients who receive first-line cetuximab combined with oxaliplatin-based chemotherapy.

Apatinib is a novel and highly selective tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2. Previous studies have suggested that apatinib is safe and effective in some solid tumors. We report one case with advanced hepatocellular carcinoma (HCC), who received apatinib combined with transhepatic arterial chemotherapy and embolization (TACE), and chemotherapy respectively. TACE was administered three times once a month, using lipiodol 10ml, oxaliplatin 150mg, and tegafur 1g. The dose of apatinib was 500 mg/d from day 4 to 24. After TACE, the patient received chemotherapy of regimen FOLFOX4, oxaliplatin intravenously at 85 mg/m2 on day 1, calcium levofolinate 200 mg/m2 on day 1 and 2, 5-fluorouracil 400 mg/m2 intravenously and 5-fluorouracil 600 mg/m2 intravenously pumped for 22h on day 1 and 2, cycled every two weeks for seven cycles. He took concurrently apatinib with a dose of 500mg daily from 1 to 10 days per cycle. He was confirmed as partial response (PR) by the Response Evaluation Criteria in Solid Tumors (RECIST). The level of serum alpha-fetoprotein (AFP) decreased from 60500 ng/ml to 12.7 ng/ml, and the progression free survival (PFS) time was more than eight months. It indicated that apatinib may be a superior choice for HCC patients. PMID:28103584

To compare treatment and toxicity outcomes between a phase 2 institutional trial of near total neoadjuvant therapy (nTNT) for locally advanced rectal cancer and a similar historical control cohort treated at Washington University in St. Louis with the current US standard of care, defined as neoadjuvant chemoradiotherapy (NCRT), total mesorectal excision (TME), and adjuvant FOLFOX chemotherapy; to expand the comparison to an additional institution, patients treated with similar NCRT at Stanford University were included. Sixty-nine patients with cT3-4N0-2M0 rectal adenocarcinoma enrolled on the Washington University in St. Louis phase 2 study of nTNT were included for analysis. Patients treated at the same institution with conventional NCRT and adjuvant FOLFOX were matched for exact cTNM stage. Forty-one patients treated with NCRT at Stanford University were included in a second analysis. Kaplan-Meier analysis with log-rank test was used to compare local control, distant metastasis-free survival, disease-free survival, and overall survival. Median follow-up was 49 and 54 months for nTNT and NCRT, respectively. Pathologic complete response and T-downstaging rates were 28% versus 16% (P=.21) and 75% versus 41% (P<.001) in the nTNT and NCRT cohorts, respectively. Three-year disease-free survival (85% vs 68%, P=.032) was significantly better in the nTNT group. Actuarial 3-year local control (92% vs 96%, P=.36) and overall survival (96% vs 88%, P=.67) were similar. The Stanford cohort had significantly lower clinical stage. After controlling for clinical stage, age, tumor location, institution, and number of chemotherapy cycles, nTNT treatment remained significantly associated with lower risk of recurrence (P=.006). Patients treated with nTNT had higher T-downstaging and superior distant metastasis-free survival and disease-free survival compared with conventional NCRT when matched for tumor location and exact cTNM stage. Near total neoadjuvant therapy remained a significant multivariate predictor for improved outcome when including patients treated with NCRT at another institution. Published by Elsevier Inc.

This phase II study aims to evaluate the efficacy and safety of biweekly cetuximab in combination with oxaliplatin, leucovorin, and fluorouracil (FOLFOX-4) as first-line treatment of metastatic wild-type KRAS colorectal cancer. Previously untreated patients with wild-type KRAS tumours received biweekly cetuximab (500 mg/m2 on day 1) plus FOLFOX-4 (oxaliplatin 85 mg/m2 on day 1, leucovorin 200 mg/m2 on days 1 and 2, and fluorouracil as a 400 mg/m2 bolus followed by a 22-hour 600 mg/m2 infusion on day 1 and 2). Treatment was continued until disease progression, onset of unacceptable toxicities, metastases surgery, or discontinuation request. The primary endpoint was ORR. The intention-to-treat population included 99 patients with a median age of 64.1 years (range, 34-82). The ORR was 60.6% (95% CI, 50.3% to 70.3%). The median follow-up was 17.8 months; the median OS and PFS were 20.8 and 10.1 months, respectively. Metastases from colorectal cancer were surgically resected in 26 (26.3%) patients, with complete resection achieved in 18 (69.2%) patients. Median PFS and OS in patients undergoing metastatic resection were 12.6 and 29.5 months, respectively. The most common grade 3-4 toxicities were neutropenia (32.3%), acne-like rash (15.2%) and diarrhoea (11.1%). The efficacy of the biweekly combination of cetuximab with FOLFOX-4 in patients with wild-type KRAS tumours supports the administration of cetuximab in a dosing regimen more convenient for patients and healthcare providers. The activity of the biweekly administration is similar to what has been reported for the weekly regimen. Reported toxicity was also consistent with the known toxicity profile of weekly cetuximab.

Systemic chemotherapy treatments, commonly those that comprise oxaliplatin, have been linked to the appearance of distinctive liver lesions that evolves to portal hypertension, spleen enlargement, platelets sequestration, and thrombocytopenia. This outcome can interrupt treatment or force dosage reduction, decreasing efficiency of cancer therapy. We conducted a prospective phase II study for the evaluation of partial splenic embolization in patients with thrombocytopenia that impeded systemic chemotherapy continuation. From August 2014 through July 2015, 33 patients underwent partial splenic embolization to increase platelets count and allow their return to treatment. Primary endpoint was the accomplishment of a thrombocyte level superior to 130 × 10 9 /L and the secondary endpoints were the return to chemotherapy and toxicity. Partial splenic embolization was done 36 times in 33 patients. All patients presented gastrointestinal cancer and colorectal malignancy was the commonest primary site. An average of 6.4 cycles of chemotherapy was done before splenic embolization and the most common regimen was Folfox. Mean platelet count prior to embolization was 69 × 10 9 /L. A total of 94% of patients achieved primary endpoint. All patients in need reinitiated treatment and median time to chemotherapy return was 14 days. No grade 3 or above adverse events were identified. Aiming for a 50% to 70% infarction area may be sufficient to achieve success without the complications associated with more extensive infarction. Combined with the better safety profile, partial splenic embolization is an excellent option in the management of thrombocytopenia, enabling the resumption of systemic chemotherapy with minimal procedure-related morbidity. © 2016 The Authors.

Lynch syndrome is an inherited syndrome with the development of the colorectal and various other cancers. Lynch syndrome is caused by mutations in the mismatch repair genes. A 33 year-old male underwent XELOX adjuvant chemotherapy for ascending colon cancer with Lynch syndrome. Although efficacy of 5-FU is not demonstrated in Lynch syndrome, MOSAIC trial had suggested a benefit from FOLFOX compared with 5-FU in patients who have colorectal cancer with Lynch syndrome. Oxaliplatin-based adjuvant chemotherapy can be a therapeutic option for colorectal cancer in lynch syndrome patients.

Tumor immunosuppression serves an important role in the occurrence and development of gastric cancer. However, the effect of chemotherapy on the immune function of patients remains unclear. The present study aimed to investigate changes in cellular immune function and regulatory T cells (Tregs) in patients with gastric cancer prior to and following chemotherapy. In the peripheral blood of patients with gastric cancer, the percentage of CD4+ T cells was substantially decreased compared with that of healthy controls (11.39±5.91 vs. 22.34±3.37%, respectively; P<0.05). High frequencies of CD8+ T cells and Tregs were also observed in the peripheral blood of patients. Although the number of T cells decreased following chemotherapy (the proportions of CD4+ and CD8+ cells were 8.99±7.31 and 16.00±4.51%, respectively), the ratio of CD4+/CD8+ T cells increased (0.31±0.17 vs. 0.56±0.22; P<0.05). Furthermore, the level of C-C motif chemokine ligand 20 (CCL20) was increased in patients prior to chemotherapy compared with healthy controls. As the sole receptor for CCL20, a high level of expression of C-C motif chemokine receptor 6 on circulating Tregs was also identified in the patients, which decreased following chemotherapy. These results suggest that chemotherapy may efficiently promote cellular immune function and inhibit immunosuppression in patients with gastric cancer.

Matrix metalloproteinase-9 (MMP9) is implicated in pro-tumorigenic processes. Andecaliximab (GS-5745, a monoclonal antibody targeting MMP9) was evaluated as monotherapy and in combination with mFOLFOX6. Three dosages of andecaliximab monotherapy (200, 600, and 1800 mg IV every 2 weeks [q2w]) were investigated in patients with advanced solid tumors (n=13 in a 3+3 design). After determining a recommended dose, patients with advanced HER2-negative gastric/gastroesophageal junction (GEJ) adenocarcinoma (n=40) received 800 mg andecaliximab + mFOLFOX6 q2w. Pharmacokinetics, pharmacodynamics, safety, and efficacy were assessed. Andecaliximab monotherapy demonstrated no dose-limiting toxicity (DLT) in any cohort, displaying target-mediated drug disposition at the lowest dose (200 mg) and linear pharmacokinetics at higher doses. Based on target engagement, recommended doses for further study are 800 mg q2w or 1200 mg q3w. Maximal andecaliximab target binding, defined as undetectable andecaliximab-free MMP9 in plasma, was observed in the gastric/GEJ adenocarcinoma cohort. We observed no unusual toxicity, although there were 4 deaths on study not attributed to andecaliximab treatment. In first-line patients (n=36), median progression free survival (PFS) was 9.9 months (95% CI 5-13.9 months) and the overall response rate (ORR) was 50%. Among all patients (n=40), median PFS was 7.8 (90% CI, 5.5-13.9) months and ORR was 48%, with a median duration of response of 8.4 months. Andecaliximab monotherapy achieved target engagement without DLT. Andecaliximab + mFOLFOX6 showed encouraging clinical activity without additional toxicity in patients with HER2-negative gastric/GEJ adenocarcinoma. A phase 3 study evaluating mFOLFOX6 +/- andecaliximab in this setting is ongoing. Copyright ©2018, American Association for Cancer Research.

The primary goal of this multicenter phase III trial was to determine whether overall survival (OS) of fluorouracil (FU) -refractory patients was noninferior when treated with second-line infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX4; arm B) versus irinotecan (arm A). Cross-over to the other treatment on disease progression was mandated. Patients who experienced treatment failure with one prior FU-based therapy and had not received prior irinotecan or oxaliplatin, either for metastatic disease or within 6 months of adjuvant FU therapy, were randomly assigned to arm A (irinotecan 350 or 300 mg/m(2) every 3 weeks) or arm B (FOLFOX4). A total of 491 patients were randomly assigned (arm A, n = 245; arm B, n = 246); 288 (59%) had experienced treatment failure with FU for metastatic colorectal cancer. Two hundred twenty-seven patients (46%) received protocol-mandated third-line therapy (arm A, 43%; arm B, 57%). Median survival was 13.8 months (95% CI, 12.2 to 15.0 months) for initial treatment with FOLFOX4 and 14.3 months (95% CI, 12.0 to 15.9 months) for irinotecan (P = .38; hazard ratio = 0.92; 95% CI, 0.8 to 1.1). Response rates (RR; 28% v 15.5%; P = .0009) and time to progression (TTP; 6.2 v 4.4 months; P = .0009) were significantly superior with FOLFOX4. In the nonrandom subset of patients who crossed over, RR and TTP improvements with FOLFOX4 continued into third-line treatment. Irinotecan therapy was associated with more grade 3 nausea, vomiting, diarrhea, and febrile neutropenia; FOLFOX4 was associated with more neutropenia and paresthesias. In patients who experienced treatment failure with front-line FU therapy, OS does not significantly differ whether second-line therapy begins with irinotecan or FOLFOX4. FOLFOX4 produces higher RR and longer TTP. Both arms had notable OS in patients who experienced treatment failure with first-line FU therapy.

Following preoperative chemoradiation and surgery, many patients with stage II to III rectal cancer are unable to tolerate full-dose adjuvant chemotherapy. BrUOG R-224 was designed to assess the impact of COmplete Neoadjuvant Treatment for REctal cancer (CONTRE), primary chemotherapy followed by chemoradiation and surgery, on treatment delivery, toxicities, and pathologic response at surgery. Patients with clinical stage II to III (T3 to T4 and/or N1 to N2) rectal cancer received 8 cycles of modified FOLFOX6 followed by capecitabine 825 mg/m bid concurrent with 50.4 Gy intensity-modulated radiation therapy. Surgery was performed 6 to 10 weeks after chemoradiation. Thirty-nine patients were enrolled between August 2010 and June 2013. Median age was 61 years (30 to 79 y); 7 patients (18%) were clinical stage II and 32 (82%) stage III. Thirty-six patients (92%) received all 8 cycles of mFOLFOX6, of whom 35 completed subsequent chemoradiation; thus 89% of patients received CONTRE as planned. No unexpected toxicities were reported. All patients had resolution of bleeding and improvement of obstructive symptoms, with no complications requiring surgical intervention. Pathologic complete response (ypT0N0) was demonstrated in 13 patients (33%; 95% CI, 18.24%-47.76%). CONTRE seems to be a well-tolerated alternative to the current standard treatment sequence. Evaluating its impact on long-term outcomes would require a large randomized trial, but using pathologic response as an endpoint, it could serve as a platform for assessing the addition of novel agents to preoperative treatment in stage II to III rectal cancer.

Evidence suggests that lean body mass (LBM) may be useful to normalize chemotherapy doses. Data from one prospective and one retrospective study were used to determine if the highest doses of oxaliplatin/kg LBM within FOLFOX regimens would be associated with dose-limiting toxicity (DLT) in colon cancer patients. Toxicity over four cycles was graded according to NCI Common Toxicity Criteria V2 or V3 (Common Terminology Criteria for Adverse Events, National Cancer Institute, Bethesda, MD). Muscle tissue was measured by computerized tomography (CT) and used to evaluate the LBM compartment of the whole body. In prospective randomized clinical trials conducted in France (n = 58), for patients given FOLFOX-based regimens according to body surface area, values of oxaliplatin/kg LBM were highly variable, ranging from 2.55 to 6.6 mg/kg LBM. A cut point of 3.09 mg oxaliplatin/kg LBM for developing toxicity was determined by Receiver Operating Characteristic (ROC) analysis, below this value 0/17 (0.0%) of patients experienced DLT; in contrast above this value 18/41 (44.0%) of patients were dose reduced or had treatment terminated owing to toxicity (≥Grade 3 or neuropathy ≥Grade 2); for 9/41 the DLT was sensory neuropathy. These findings were validated in an independent cohort of colon cancer patients (n = 80) receiving FOLFOX regimens as part of standard care, in Canada. Low LBM is a significant predictor of toxicity and neuropathy in patients administered FOLFOX-based regimens using conventional body surface area (BSA) dosing. © 2016 The Authors.

Systemic FOLFOX (folinic acid (leucovorin (LV)), 5-fluorouracil (5-FU), and oxaliplatin), FOLFIRI (LV, 5-FU, and irinotecan), or FOLFOXIRI (5-FU, leucovorin, oxaliplatin, and irinotecan) chemotherapy regimens and additional molecular-target treatments, including anti-vascular endothelial growth factor, anti-epidermal growth factor receptor, and anti-multi-kinase antibodies, have been recommended for unresectable recurrent colorectal cancers. However, no effective treatments are currently available for cases refractory to these therapies. Therefore, the development of alternative therapies is desired. In the present study, we administered and observed the effectiveness of hepatic artery infusion therapy (HAIC) in patients with unresectable liver metastatic colorectal cancers refractory to systemic chemotherapy. In addition, we observed that in an experimental system with anticancer drug-resistant colorectal cancer lines, apoptosis and cell death could be induced by increasing anticancer drug concentrations. The subjects had liver metastatic colorectal cancers that were unresponsive to systemic chemotherapy (FOLFOX/FOLFIRI) or to additional molecular-target therapies for progressive disease. Hepatic infusion tube placement was conducted according to the Seldinger method to insert a catheter with a side hole via the right femoral artery. A coiling procedure was performed to prevent drug influx into the gastroduodenal artery. Ten subjects were selected, and the results were evaluated after HAIC (5-FU and LV administered once weekly). Moreover, anticancer drug-resistant colorectal cancer lines were subsequently prepared to investigate whether increased anticancer drug concentrations could induce apoptosis or cell death. Of the 10 subjects, 3 (30 %) showed partial response and 4 (40 %) showed no change according to computed tomography imaging findings obtained after hepatic artery infusion. The disease control rate was 70 %. Eight subjects had improved quality of life. Survival time ranged from 2 to 16 months (median, 9 months). Meanwhile, we found that higher anticancer drug concentrations induced apoptosis and cell death in an anticancer drug-resistant colorectal cancer cell line. HAIC was effective in some systemic chemotherapy-resistant colorectal cancers with liver metastases and should be considered as an effective palliative therapy. This supports the finding that apoptosis and cell death could be induced in anticancer drug-resistant colorectal cancer cells in a drug concentration-dependent manner.

Previously, we reported results of Intergroup N9741, which compared standard bolus fluorouracil (FU), leucovorin, plus irinotecan (IFL) with infused FU, leucovorin, plus oxaliplatin (FOLFOX4) and irinotecan plus oxaliplatin in patients with untreated metastatic colorectal cancer. High rates of grade > or = 3 toxicity on IFL (resulting in some deaths) led us to reduce the starting doses of both irinotecan and FU by 20% (rIFL). This article compares rIFL with FOLFOX4. The primary comparison was time to progression, with secondary end points of response rate (RR), overall survival, and toxicity. Three hundred five patients were randomly assigned. The North Central Cancer Treatment Group Data Safety Monitoring Committee interrupted enrollment at a planned interim analysis when outcomes crossed predetermined stopping boundaries. The results were significantly superior for FOLFOX4 compared with rIFL for time to progression (9.7 v 5.5 months, respectively; P < .0001), RR (48% v 32%, respectively; P = .006), and overall survival (19.0 v 16.3 months, respectively; P = .026). Toxicity profiles were not significantly different between regimens for nausea, vomiting, diarrhea, febrile neutropenia, dehydration, or 60-day all-cause mortality. Sensory neuropathy and neutropenia were significantly more common with FOLFOX4. Approximately 75% of patients in both arms received second-line therapy; 58% of rIFL patients received oxaliplatin-based second-line therapy, and 55% of FOLFOX4 patients received irinotecan-based regimens as second-line therapy. FOLFOX4 led to superior RR, time to progression, and overall survival compared with rIFL. The survival benefit for FOLFOX4 observed in the earlier stage of the study was preserved with equal use of either irinotecan or oxaliplatin as second-line therapy.

Purpose The primary goal of this multicenter phase III trial was to determine whether overall survival (OS) of fluorouracil (FU) -refractory patients was noninferior when treated with second-line infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX4; arm B) versus irinotecan (arm A). Cross-over to the other treatment on disease progression was mandated. Patients and Methods Patients who experienced treatment failure with one prior FU-based therapy and had not received prior irinotecan or oxaliplatin, either for metastatic disease or within 6 months of adjuvant FU therapy, were randomly assigned to arm A (irinotecan 350 or 300 mg/m2 every 3 weeks) or arm B (FOLFOX4). Results A total of 491 patients were randomly assigned (arm A, n = 245; arm B, n = 246); 288 (59%) had experienced treatment failure with FU for metastatic colorectal cancer. Two hundred twenty-seven patients (46%) received protocol-mandated third-line therapy (arm A, 43%; arm B, 57%). Median survival was 13.8 months (95% CI, 12.2 to 15.0 months) for initial treatment with FOLFOX4 and 14.3 months (95% CI, 12.0 to 15.9 months) for irinotecan (P = .38; hazard ratio = 0.92; 95% CI, 0.8 to 1.1). Response rates (RR; 28% v 15.5%; P = .0009) and time to progression (TTP; 6.2 v 4.4 months; P = .0009) were significantly superior with FOLFOX4. In the nonrandom subset of patients who crossed over, RR and TTP improvements with FOLFOX4 continued into third-line treatment. Irinotecan therapy was associated with more grade 3 nausea, vomiting, diarrhea, and febrile neutropenia; FOLFOX4 was associated with more neutropenia and paresthesias. Conclusion In patients who experienced treatment failure with front-line FU therapy, OS does not significantly differ whether second-line therapy begins with irinotecan or FOLFOX4. FOLFOX4 produces higher RR and longer TTP. Both arms had notable OS in patients who experienced treatment failure with first-line FU therapy. PMID:19380443

Appendix goblet cell carcinoids are known to share histological features of adenocarcinoma and neuroendocrine tumours. Due to their low incidence, quality evidence is lacking for the management of these patients. We performed a single-centre retrospective study of patients with a confirmed diagnosis of appendiceal goblet cell carcinoid (GCC; 1996-2014). Patients were divided into curative intent (CI) and palliative intent (PI) cohorts. Our primary end point was overall survival (OS). Seventy-four patients were eligible; 76% were treated with CI [surgery only (36%), cytoreductive surgery (CRS) and hyperthermic intra-peritoneal chemotherapy (HIPEC; 36%), adjuvant chemotherapy (20%) and a combination of CRS and HIPEC followed by adjuvant chemotherapy (9%)], and 23% had advanced-stage disease amenable to palliative treatment (chemotherapy or supportive care) only. Completion right hemicolectomy, performed in 64% of the CI cohort, did not impact on the relapse rate or disease-free survival. FOLFOX chemotherapy was used in both the adjuvant and palliative settings; safety was as expected, and we observed a high rate (60%) of disease control in the palliative cohort. The estimated median OS (all patients), disease-free survival (CI patients) and progression-free survival (PI patients) were 52.1 (95% CI 29.4-90.3), 75.9 (26.6-not reached) and 5.3 (0.6-5.7) months, respectively. Age and stage were independent factors associated with OS in the multivariable analysis. Tang classification showed a trend for impact on OS. No benefit from specific adjuvant approach was identified; however, selection bias for treatment approach was observed. Prospective trials are needed to define optimal approaches in GCC. All GCC patients should be managed by specialized centres due to their esoteric behaviour; we provide management considerations based on our experience and conclusions. © 2015 S. Karger AG, Basel.

Primary adenocarcinoma of the appendix is a rare malignancy that constitutes < 0.5% of all gastrointestinal neoplasms. Moreover, primary signet ring cell carcinoma of the appendix is an exceedingly rare entity. We have encountered 15 cases of primary appendiceal cancer among 3389 patients who underwent appendectomy over the past 18 years. In the present report, we describe a rare case of primary signet ring cell carcinoma of the appendix with ovarian metastases and unresectable peritoneal dissemination occurring in a 67-year-old female patient. She underwent appendectomy and bilateral salpingo-oophorectomy with a laparoscopy procedure. She then received palliative systemic chemotherapy with 12 cycles of oxaliplatin, 5-fluorouracil, and leucovorin (FOLFOX-4). The patient currently is well without progression of disease 12 mo after beginning chemotherapy. PMID:18837098

Brain metastasis from colorectal cancer is infrequent and carries a poor prognosis. Herein, we present a patient alive 10 years after the identification of a first brain metastasis from sigmoid colon cancer. A 39-year-old woman underwent sigmoidectomy for sigmoid colon cancer during an emergency operation for pelvic peritonitis. The pathological finding was moderately differentiated adenocarcinoma. Eleven months after the sigmoidectomy, a metastatic lesion was identified in the left ovary. Despite local radiotherapy followed by chemotherapy, the left ovarian lesion grew, so resection of the uterus and bilateral ovaries was performed. Adjuvant chemotherapy with tegafur-uracil (UFT)/calcium folinate (leucovorin, LV) was initiated. Seven months after resection of the ovarian lesion, brain metastases appeared in the bilateral frontal lobes and were treated with stereotactic Gamma Knife radiosurgery. Cervical and mediastinal lymph node metastases were also diagnosed, and irradiation of these lesions was performed. After radiotherapy, 10 courses of oxaliplatin and infused fluorouracil plus leucovorin (FOLFOX) were administered. During FOLFOX administration, recurrent left frontal lobe brain metastasis was diagnosed and treated with stereotactic Gamma Knife radiosurgery. In this case, the brain metastases were well treated with stereotactic Gamma Knife radiosurgery, and the systemic disease arising from sigmoid colon cancer has been kept under control with chemotherapies, surgical resection, and radiotherapy.

Here, we report the case of a 43-year-old man who was diagnosed with sigmoid colon cancer with synchronous multiple liver metastases following resection of a primary lesion. Subsequent mFOLFOX+BV therapy elicited a marked response in the liver metastases, which led to the patient undergoing hepatic (S7) radiofrequency ablation (RFA), hepatic resection (lateral segmentectomy and partial [S5] resection), and cholecystectomy. Six months later, transluminal RFA was repeated because liver (S7) metastasis recurred, and 8 courses of XELOX plus BV therapy were administered. As obstructive jaundice due to recurrence of the liver metastases developed after a 6 months hiatus in chemotherapy, we endoscopically inserted a biliary stent. Despite reducing IRIS plus BV therapy, obstructive jaundice developed again, and 3 intrahepatic biliary stents were inserted with percutaneous transhepatic biliary drainage. To date, the patient has been alive for 4 years since the initial resection of the primary lesion after undergoing consecutive systemic chemotherapy with different regimens. Some studies have shown that in cases of obstructive jaundice caused by advanced gastrointestinal cancer, longer survival could be expected by reducing the severity of jaundice, suggesting that resuming chemotherapy as well as improving the severity of jaundice could contribute to better outcomes. The patient in the present case was successfully treated twice with biliary drainage for occlusive jaundice and chemotherapy, suggesting that a combination of multidisciplinary therapy and adequate local therapy such as biliary drainage could be important for the treatment of metastatic liver cancer.

Reports of conversion in cases of locally advanced colorectal cancer have been increasing. Here, we present 2 cases in which curative resection of locally advanced rectal cancer accompanied by intestinal obstruction was achieved after establishing a stoma and administering chemotherapy. The first case was of a 46-year-old male patient diagnosed with upper rectal cancer and intestinal obstruction. Because of a high level of retroperitoneal invasion, after establishing a sigmoid colostomy, 13 courses of mFOLFOX6 plus Pmab were administered. Around 6 months after the initial surgery, low anterior resection for rectal cancer and surgery to close the stoma were performed. Fourteen days after curative resection, the patient was discharged from the hospital. The second case was of a 66-year-old male patient with a circumferential tumor extending from Rs to R, accompanied by right ureter infiltration and sub-intestinal obstruction. After establishing a sigmoid colostomy, 11 courses of mFOLFOX6 plus Pmab were administered. Five months after the initial surgery, anterior resection of the rectum and surgery to close the stoma were performed. Twenty days after curative resection, the patient was released from the hospital. No recurrences have been detected in either case.

We conducted a phase I study to determine the maximum tolerated dose of vorinostat in combination with fixed doses of 5-fluorouracil (FU), leucovorin, and oxaliplatin (FOLFOX). Vorinostat was given orally twice daily for 1 week every 2 weeks. FOLFOX was given on days 4 and 5 of vorinostat. The vorinostat starting dose was 100 mg twice daily. Escalation occurred in cohorts of three to six patients. Pharmacokinetics of vorinostat, FU, and oxaliplatin were studied. Twenty-one patients were enrolled. Thrombocytopenia, neutropenia, gastrointestinal toxicities, and fatigue increased in frequency and severity at higher dose levels of vorinostat. Two of 4 evaluable patients at dose level 4 (vorinostat 400 mg orally twice daily) developed dose-limiting fatigue. One of 10 evaluable patients at dose level 3 (vorinostat 300 mg orally twice daily) had dose-limiting fatigue, anorexia, and dehydration. There were significant relationships between vorinostat dose and the area under the curve on days 1 and 5 (Pearson, < 0.001). The vorinostat area under the curve increased (P = 0.005) and clearance decreased (P = 0.003) on day 5 compared with day 1. The median C(max) of FU at each dose level increased significantly with increasing doses of vorinostat, suggesting a pharmacokinetic interaction between FU and vorinostat. Vorinostat-induced thymidylate synthase (TS) modulation was not consistent; only two of six patients had a decrease in intratumoral TS expression by reverse transcription-PCR. The maximum tolerated dose of vorinostat in combination with FOLFOX is 300 mg orally twice daily x 1 week every 2 weeks. Alternative vorinostat dosing schedules may be needed for optimal down-regulation of TS expression.

Purpose We conducted a phase I study to determine the maximum tolerated dose (MTD) of vorinostat in combination with fixed doses of 5-Fluorouracil (5-FU), leucovorin, and oxaliplatin (FOLFOX). Experimental Design Vorinostat was given PO BID for 1 week every 2 weeks. FOLFOX was given on days 4 and 5 of vorinostat. The vorinostat starting dose was 100 mg BID. Escalation occurred in cohorts of 3–6 patients. Pharmacokinetics of vorinostat, 5-FU, and oxaliplatin were studied. Results Twenty-one patients were enrolled. Thrombocytopenia, neutropenia, gastrointestinal toxicities, and fatigue increased in frequency and severity at higher dose-levels (DL) of vorinostat. Two of 4 evaluable patients at DL 4 (vorinostat 400 mg PO BID) developed dose-limiting fatigue. One of 10 evaluable patients at DL3 (vorinostat 300 mg PO BID) had dose-limiting fatigue, anorexia, and dehydration. There were significant relationships between vorinostat dose and AUC on days 1 and 5 (Pearson, < 0.001). Vorinostat AUC increased (p = 0.005) and clearance decreased (p = 0.003) on day 5 compared to day 1. The median Cmax of 5-FU at each DL increased significantly with increasing doses of vorinostat, suggesting a pharmacokinetic interaction between 5-FU and vorinostat. Vorinostat-induced thymidylate synthase modulation was not consistent; only two of six patients had a decrease in intra-tumoral thymidylate synthase expression by RT-PCR. Conclusions The MTD of vorinostat in combination with FOLFOX is 300 mg PO BID x 1 week every two weeks. Alternative vorinostat dosing schedules may be needed for optimal down-regulation of thymidylate synthase expression. PMID:19383814

Cachexia affects the majority of cancer patients, with currently no effective treatments. Cachexia is defined by increased fatigue and loss of muscle function resulting from muscle and fat depletion. Previous studies suggest that chemotherapy may contribute to cachexia, although the causes responsible for this association are not clear. The purpose of this study was to investigate the mechanism(s) associated with chemotherapy-related effects on body composition and muscle function. Normal mice were administered chemotherapy regimens used for the treatment of colorectal cancer, such as Folfox (5-FU, leucovorin, oxaliplatin) or Folfiri (5-FU, leucovorin, irinotecan) for 5 weeks. The animals that received chemotherapy exhibited concurrent loss of muscle mass and muscle weakness. Consistently with previous findings, muscle wasting was associated with up-regulation of ERK1/2 and p38 MAPKs. No changes in ubiquitin-dependent proteolysis or in the expression of TGFβ-family members were detected. Further, marked decreases in mitochondrial content, associated with abnormalities at the sarcomeric level and with increase in the number of glycolytic fibers were observed in the muscle of mice receiving chemotherapy. Finally, ACVR2B/Fc or PD98059 prevented Folfiri-associated ERK1/2 activation and myofiber atrophy in C2C12 cultures. Our findings demonstrate that chemotherapy promotes MAPK-dependent muscle atrophy as well as mitochondrial depletion and alterations of the sarcomeric units. Therefore, these findings suggest that chemotherapy potentially plays a causative role in the occurrence of muscle loss and weakness. Moreover, the present observations provide a strong rationale for testing ACVR2B/Fc or MEK1 inhibitors in combination with anticancer drugs as novel strategies aimed at preventing chemotherapy-associated muscle atrophy.

A 46-year old man presented with lower right quadrant abdominal pain caused by abdominal trauma. Abscess drainage was performed after the diagnosis of retroperitoneal abscess in the ileocecal portion of the colon. Type 2 advanced cancer was found in the cecum and ascending colon. Surgery was performed after improvement of inflammation. Considering the difficulty of curative resection for retroperitoneal invasion, we first performed ileo-transverse colon anastomosis. After surgery, the patient received FOLFOX with panitumumab(Pmab)as neoadjuvant chemotherapy. After 6 courses of this regimen, contrast enhanced computed tomography revealed shrinkage of the tumor. We performed a second surgery but the tumor was unresectable because of retroperitoneal invasion. After 47 courses of chemotherapy(5-FU plus LV with Pmab), the tumor was stable and we observed no distant metastasis. A third surgery was performed, and we were able to perform ileocecal resection including the retroperitoneum. The pathological diagnosis was pT4b(SI), pN1, ly2, V2, pPM0, pDM0, R0, pStage III a. On histological examination, the efficacy of chemotherapy was evaluated as Grade 1a. The patient received adjuvant chemotherapy with capecitabine and remains healthy without any evidence of recurrence more than 10 months after surgery.

Objectives We sought to predict oxaliplatin-associated peripheral neuropathy during modified FOLFOX6 (mFOLFOX6) therapy. Methods In a 50% female sample, patients with previously untreated, primary or recurrent colorectal cancer were followed through a first course of mFOLFOX6 with oxaliplatin 85 mg/m2 every 2 weeks. Accounting for correlation among a subject's cycles, logistic regression estimated per-cycle risk of acute (under 14 days) and persistent (14 days or more) neuropathy. Proportional hazards regression predicted time to persistent neuropathy. Results Among mFOLFOX6 recipients (n=50, age 58.9 +10.1 years), 36% received concomitant bevacizumab. Of total cycles, 94.2% (422/448) were evaluable. Most (84%) subjects reported neuropathy at least once: 74% reported acute and 48% reported persistent symptoms. On multivariate analysis, risk factors shared by acute and persistent neuropathy were body-surface area >2.0, acute neuropathy in a past cycle, and lower body weight. In addition, risk of acute neuropathy decreased with age (adjusted for renal function and winter season), while risk of persistent neuropathy increased with cumulative dose of oxaliplatin and persistent neuropathy in a past cycle. Concomitant bevacizumab was not a risk factor when administered in Stage IV disease but was associated with persistent neuropathy when administered experimentally in Stage III. Females had no increased risk of either form of neuropathy. After 3 cycles, weight, body-surface area, and prior acute neuropathy predicted time to persistent neuropathy. Conclusions Routinely available clinical factors predict acute and persistent neuropathy associated with oxaliplatin. When validated, the proposed prognostic score for persistent neuropathy can help clinicians counsel patients about chemotherapy. PMID:22547012

To compare efficacy and toxicity of bolus application of chemotherapy protocol, oxaliplatin, fluorouracil (bolus), leucovorin (folfox) between two groups of patients in the therapy of metastatic colorectal carcinoma (mCRC). A total of 63 patients were treated for mCRC in the period January 2009 - January 2010 at the Department of Oncology of the Cantonal Hospital Zenica, Bosnia and Herzegovina (first group, 30 patients) and at the Department of Oncology of the Clinical Hospital Centre Bežanijska kosa in Belgrade, Serbia, in the period January 2005 - January 2006 (second group, 33 patients). The patients were treated according the same protocol, i.v. bolus infusion, but in different day intervals (D), 1, 8, 15/28 days or D1-D5/28 days, respectively. In all patients the following factors were analyzed: tumor response, overall survival (OS), progression free survival, hematological and non-hematological toxicity . Colon was the primary localization in almost two thirds of patients. There was no statistically significant difference between the groups according to the age, hematological and non-hematological toxicity, as well as in achieved OS. Progression free survival expressed in months was in average 5 months though with a large range between minimal and maximal survival time. Both groups have shown equivalent efficacy to applied chemotherapy protocols. Overall survival in the two groups matched data from the literature. Further research should confirm success of the combination of chemotherapy protocols and their combination with the biological therapy. Copyright© by the Medical Assotiation of Zenica-Doboj Canton.

To assess the cost-effectiveness of panitumumab in combination with mFOLFOX6 (oxaliplatin, 5-fluorouracil, and leucovorin) vs bevacizumab in combination with mFOLFOX6 as first-line treatment of patients with wild-type RAS metastatic colorectal cancer (mCRC) in Spain. A semi-Markov model was developed including the following health states: Progression free; Progressive disease: Treat with best supportive care; Progressive disease: Treat with subsequent active therapy; Attempted resection of metastases; Disease free after metastases resection; Progressive disease: after resection and relapse; and Death. Parametric survival analyses of patient-level progression free survival and overall survival data from the PEAK Phase II clinical trial were used to estimate health state transitions. Additional data from the PEAK trial were considered for the dose and duration of therapy, the use of subsequent therapy, the occurrence of adverse events, and the incidence and probability of time to metastasis resection. Utility weightings were calculated from patient-level data from panitumumab trials evaluating first-, second-, and third-line treatments. The study was performed from the Spanish National Health System (NHS) perspective including only direct costs. A life-time horizon was applied. Probabilistic sensitivity analyses and scenario sensitivity analyses were performed to assess the robustness of the model. Based on the PEAK trial, which demonstrated greater efficacy of panitumumab vs bevacizumab, both in combination with mFOLFOX6 first-line in wild-type RAS mCRC patients, the estimated incremental cost per life-year gained was €16,567 and the estimated incremental cost per quality-adjusted life year gained was €22,794. The sensitivity analyses showed the model was robust to alternative parameters and assumptions. The analysis was based on a simulation model and, therefore, the results should be interpreted cautiously. Based on the PEAK Phase II clinical trial and taking into account Spanish costs, the results of the analysis showed that first-line treatment of mCRC with panitumumab + mFOLFOX6 could be considered a cost-effective option compared with bevacizumab + mFOLFOX6 for the Spanish NHS.

We evaluated the advantages and disadvantages of Huber Plus through three outpatients treated with central venous (CV) port chemotherapy (FOLFOX). One of the three outpatients first received chemotherapy with safety huber (Huber Plus) in this study, and the huber needle was changed from non-safety to a safety huber (Huber Plus) in two of the three outpatients. All three outpatients were taught about needle removal methods and port care. In patients? education, 1) we used a skin model and training CV port, and 2) dressing materials were used as film dressing plus three-point fixation by Fixomull stretch. As a result, the safety system assured zero incidents. Moreover, the evaluation revealed that operability and pain of Huber Plus were not clinical problems. We suggest that Huber Plus is applicable in outpatient chemotherapy and that our care plan with patients? education might become a standard treatment.

The National Institute for Health and Clinical Excellence (NICE) invited the manufacturer of bevacizumab (Roche Products) to submit evidence for the clinical and cost effectiveness of this drug for the treatment of patients with metastatic colorectal cancer (mCRC), as part of the Institute's Single Technology Appraisal (STA) process. The School of Health and Related Research (ScHARR) at the University of Sheffield was commissioned to act as the Evidence Review Group (ERG). This paper provides a description of the company submission, the ERG review and NICE's subsequent decisions. The ERG produced a critical review of the evidence for the clinical and cost effectiveness of the technology provided within the manufacturer's submission to NICE. The ERG also independently searched for relevant evidence and modified the manufacturer's decision analytic model to examine the impact of altering some of the key assumptions. The main clinical effectiveness data were derived from a phase III, multicentre, multinational, two-arm, randomized, open-label study with the primary objective of confirming the non-inferiority of oxaliplatin plus capecitabine (XELOX) compared with oxaliplatin plus 5-fluorouracil and folinic acid (FOLFOX-4) in adult patients with histologically confirmed mCRC who had not previously been treated. The ERG considered that the NO16966 trial was of reasonable methodological quality and demonstrated a significant improvement in both progression-free and overall survival when bevacizumab is added to either XELOX or FOLFOX-4. The ERG considered that the size of the actual treatment effect of bevacizumab was uncertain due to trial design limitations, imbalance of a known prognostic factor, relatively short treatment duration compared with that allowed within the trial protocol, and interpretation of the statistical analyses. The manufacturer's submission included a de novo economic evaluation using a cost-effectiveness model built in Microsoft® Excel. The ERG believed that the modelling structure employed was appropriate but highlighted several areas of uncertainty that had the potential to have a significant impact on the resulting incremental cost-effectiveness ratios (ICERs). The areas of uncertainty identified by the ERG included whether chemotherapy would be administered continuously or intermittently, patient access scheme (PAS) costs and uptake, survival that was dependent on the statistical analyses used, and the likely duration of continued treatment with bevacizumab after cessation of oxaliplatin and the efficacy associated with continuation. The STA described here highlighted the challenges in appraising interventions with a complex PAS. Based on the analyses that include a discount to the list price of oxaliplatin, the ERG concluded that the ICERs for the addition of bevacizumab to XELOX or FOLFOX were both over £50 000. The NICE Appraisal Committee concluded that bevacizumab in combination with oxaliplatin and either 5-fluorouracil plus folinic acid or capecitabine (i.e. FOLFOX or XELOX) was not recommended for the treatment of mCRC.

The study is designed to assess the frequency and severity of few dose limiting neurological adverse effects of four different schedules of FOLFOX. Patients with histologically confirmed advanced colorectal carcinoma (CRC) were included in the study. Toxicity was graded according to CTC v 2.0. The frequency of grade 3 and 4 adverse effects was comparatively assessed in each treatment arm. The difference in the pattern of toxicity between the treatment schedule was evaluated. The most frequent adverse symptom of neurological adverse effect was grade 1 paresthesia in the patients treated with FOLFOX4 schedule. Grade 4 peripheral neuropathy was reported in few patients of FOLFOX7 treatment arm. Frequency and onset of neurological adverse effects like paresthesia, dizziness, and hypoesthesia were significantly different (P < 0.05), whereas frequency and onset of peripheral neuropathy were highly significant (P < 0.01) in each treatment arm of FOLFOX. Peripheral neuropathy was associated with electrolyte imbalance and diabetes in few patients. Frequency of symptoms, for example, paresthesia, is associated with increased number of recurrent exposure to oxaliplatin (increased number of cycles) even at low doses (85 mg/m2), whereas severity of symptoms, for example, peripheral neuropathy, is associated with higher dose (130 mg/m2) after few treatment cycles.

With modern multimodality therapy, patients with resected colorectal cancer (CRC) liver metastases (CLM) can experience up to 50-60 % 5-year survival. These improved outcomes have become more commonplace via achievements in multidisciplinary care, improved definition of resectability, and advances in technical skill. Even patients with synchronous and/or extensive bilateral disease have benefited from novel surgical strategies. Treatment sequencing of synchronous CRC with CLM can be simplified into the following three paradigms: (classic colorectal-first), simultaneous (combined), or reverse approach (liver-first). The decision of whether to treat the CLM or CRC first depends on which site dominates oncologically and symptomatically. Oxaliplatin with 5-fluorouracil/leucovorin (FOLFOX) and irinotecan with 5-fluorouracil/leucovorin (FOLFIRI) are the foundations of modern chemotherapy. Although each regimen has positively impacted survivals, both have the potential for negative effects on the non-tumor liver. Oxaliplatin is associated with vascular injury (sinusoidal ballooning, microvascular injury, nodular regenerative hyperplasia, and long-term fibrosis) but not steatosis. Irinotecan has been associated with steatohepatitis, especially in patients with obesity and diabetes. Steatohepatitis from irinotecan is the only chemotherapy-associated liver injury (CALI) associated with increased mortality from postoperative hepatic insufficiency. Extended duration of preoperative chemotherapy is also associated with CALI. To determine resectability and to prevent overtreatment with systemic therapy, all patients should receive high-quality cross-sectional imaging and be evaluated by a hepatobiliary surgeon before starting chemotherapy. Even as chemotherapy improves, liver surgeons will continue to play a central role in treatment planning by offering the best chance for prolonged survival-safe R0 resection with curative intent.

Colorectal cancer (CRC) has been associated with high levels of lipid peroxidation, probably due to neoplasic tissue metabolism. Our objectives were to relate lipid peroxidation with the evolution of CRC and with various biomarkers (GGT, ALP, LDH, CEA) to assess its prognostic value. A longitudinal study was conducted with CRC patients (n=43), using FOLFOX4. At the end of the treatment, patients were grouped into two groups: poor outcome (PO) for those patients whose computed tomography showed signs of metastasis, not reduced or increased in the previous implants, and not reduced or increased in CEA levels and good outcome (GO) for the opposite trends. PO patients had a significant increase in TBARS levels, being different from other group in cycles 4, 5, and 6 of chemotherapy. After cycle 6 of chemotherapy, GO patients had higher SOD (27%) and catalase (33%) activity. TBARS levels showed a positive correlation with biomarkers at the beginning of the treatment, which disappeared after six cycles of chemotherapy, when TBARS levels of the PO group started to increase; the other parameters increased at a later time. Because the serum TBARS levels in GO patients did not increase after the beginning of chemotherapy, it is expected that the increase is not a result of the effects of chemotherapy but of sickness evolution. It is possible that the systemic assessment of lipid peroxidation might become an additional marker because it occurs earlier than other biomarkers and could therefore be useful in the prognosis of CRC patients.

Colorectal cancer patients with unresectable liver-only metastases may be cured after downsizing of metastases by neoadjuvant systemic therapy. However, the optimal neoadjuvant induction regimen has not been defined, and the lack of consensus on criteria for (un)resectability complicates the interpretation of published results. CAIRO5 is a multicentre, randomised, phase 3 clinical study. Colorectal cancer patients with initially unresectable liver-only metastases are eligible, and will not be selected for potential resectability. The (un)resectability status is prospectively assessed by a central panel consisting of at least one radiologist and three liver surgeons, according to predefined criteria. Tumours of included patients will be tested for RAS mutation status. Patients with RAS wild type tumours will be treated with doublet chemotherapy (FOLFOX or FOLFIRI) and randomised between the addition of either bevacizumab or panitumumab, and patients with RAS mutant tumours will be randomised between doublet chemotherapy (FOLFOX or FOLFIRI) plus bevacizumab or triple chemotherapy (FOLFOXIRI) plus bevacizumab. Radiological evaluation to assess conversion to resectability will be performed by the central panel, at an interval of two months. The primary study endpoint is median progression-free survival. Secondary endpoints are the R0/1 resection rate, median overall survival, response rate, toxicity, pathological response of resected lesions, postoperative morbidity, and correlation of baseline and follow-up evaluation with respect to outcomes by the central panel. CAIRO5 is a prospective multicentre trial that investigates the optimal systemic induction therapy for patients with initially unresectable, liver-only colorectal cancer metastases. CAIRO 5 is registered at European Clinical Trials Database (EudraCT) (2013-005435-24). CAIRO 5 is registered at ClinicalTrials.gov: NCT02162563 , June 10, 2014.

A 63-year-old man with bloody stools, anal incompetence, and feeling of fatigue was diagnosed as having a RAS mutanttype rectal cancer with abscess and rectovesical fistula. Computed tomography revealed that the tumor had invaded the seminal vesicle, prostate, and bladder and formed an abscess. In addition, his general condition was poor. Thus, we evaluated the lesion as unresectable. His nutritional status improved, and the infection was controlled after colostomy. Then, we performed chemotherapy with 5-fluorouracil, Leucovorin, and oxaliplatin(FOLFOX)plus bevacizumab. However, after a single course of chemotherapy, the systemic inflammatory reaction was prolonged. Despite treatment of the infection with antibiotics, it was not fully controlled, making it difficult to continue chemotherapy. A new lesion did not appear, but the primary tumor increased in size. Thus, we performed pelvic exenteration. Pathological examination revealed that the tumor was a well-differentiated adenocarcinoma invading the sigmoid colon and bladder. We resected it curatively and administered adjuvant chemotherapy postoperatively. No recurrence was observed during 10 months' follow-up.

In this era of oxaliplatin-based adjuvant therapy, the optimal sequence in which chemoradiotherapy should be administered for pathological stage N2 rectal cancer is unknown. The aim of this study was to investigate this sequence. In the primary adjuvant concurrent chemoradiotherapy (A-CRT) group (n = 71), postoperative concurrent chemoradiotherapy was administered before adjuvant chemotherapy. In the primary adjuvant chemotherapy (A-CT) group (n = 43), postoperative concurrent chemoradiotherapy was administered during or after adjuvant chemotherapy. Postoperative radiotherapy comprised 45-50.4 Gy in 25-28 fractions. Concurrent chemotherapy comprised two cycles of oral capecitabine (1,600 mg/m 2 ) on days 1-14 and 22-35. Patients receiving adjuvant chemotherapy with four or more cycles of XELOX (oxaliplatin plus capecitabine) or eight or more cycles of FOLFOX (fluorouracil, leucovorin, and oxaliplatin) were included. Between June 2005 and December 2013, data for 114 qualified rectal cancer patients were analyzed. The percentages of patients in whom treatment failed in the A-CRT and A-CT groups were 33.8% and 16.3%, respectively (p = 0.042). More patients had distant metastases in the A-CRT group than in the A-CT group (32.4% vs. 14.3%, p = 0.028). Multivariate analysis indicated that the sequence in which chemoradiotherapy was administered (A-CT vs. A-CRT) was an independent prognostic factor for both estimated disease-free survival [hazard ratio (HR) 0.345, 95% confidence interval (CI) 0.137-0.868, p = 0.024] and estimated distant metastasis-free survival (HR 0.366, 95% CI 0.143-0.938, p = 0.036). In pathological stage N2 rectal cancer patients, administering adjuvant chemotherapy before chemoradiotherapy led to a lower rate of treatment failure, especially with respect to distant metastasis. Adjuvant chemotherapy prescribed as early as possible might benefit this cohort of patients in this era of oxaliplatin-based adjuvant therapy.

We report a case of pneumocystis pneumonia (PCP) during adjuvant chemotherapy for advanced sigmoid colon cancer. A 70-year-old Japanese man was referred to our hospital after complaining of bloody stools. He was diagnosed with advanced sigmoid colon cancer, T2N2aM1b, Stage IV B. After 3 cycles of mFOLFOX6 plus panitumumab as first-line chemotherapy, he received FOLFIRI plus bevacizumab as second-line chemotherapy because of progressive disease. Aprepitant and steroids were administered as antiemetic agents for a short period during each chemotherapy session. During the 2 cycle of FOLFIRI plus bevacizumab, he developed a high fever without respiratory symptoms. Chest CT revealed ground-glass opacities in both the lungs. We first treated him with antibiotics (PIPC/TAZ plus GRNX), suspecting bacterial pneumonia. However, based on the elevation of serum b -D-glucan (148 pg/mL), we diagnosed PCP and initiated SMX/TMP in addition to PIPC/TAZ. The inflammation promptly decreased, and follow-up chest CT revealed the disappearance of the ground-glass opacities. If a patient develops a fever or respiratory symptoms during a course of chemotherapy, we should consider the possibility of PCP and perform careful examinations.

Here we report 2 cases of curative resection following preoperative chemotherapy with bevacizumab for locally advanced colon cancer. Case 1 was a 62-year-old man admitted with constipation, abdominal distention, and abdominal pain. An abdominal computed tomography(CT)scan revealed an obstructive tumor of the sigmoid colon with invasion into the bladder. A diverting colostomy was performed, and chemotherapy with mFOLFOX6(infusional 5-fluorouracil/Leucovorin+ oxaliplatin) plus bevacizumab was initiated. The tumor shrunk markedly after 6 courses of this treatment. Thereafter, laparoscopy- assisted sigmoidectomy was successfully performed. Case 2 was a 61-year-old woman admitted with diarrhea, abdominal pain, and fever. An abdominal CT scan revealed an obstructive tumor of the sigmoid colon with invasion into the ileum, uterus and retroperitoneum. A diverting colostomy was performed, and chemotherapy with XELOX(capecitabine+ oxaliplatin)plus bevacizumab was initiated. The tumor shrunk markedly after 6 courses of this treatment. Thereafter, laparoscopy- assisted sigmoidectomy was successfully performed. Both cases demonstrated partial clinical responses to chemotherapy; thus, curative resection surgeries were performed. There were no perioperative complications. Therefore, we conclude that oxaliplatin-based chemotherapy plus bevacizumab and laparoscopic resection could be very effective for locally advanced colon cancer.

The use of neoadjuvant radiation therapy and chemotherapy in the treatment of locally advanced rectal adenocarcinoma has been shown to reduce disease recurrence when combined with surgery and adjuvant chemotherapy. We report a case of a patient who developed a debilitating bilateral myopathy of the hip flexors after successful treatment for rectal cancer. To the best of our knowledge, this is the first such complication from radiation therapy reported in a patient with colorectal cancer. The disproportionate severity of our patient's myopathy relative to the dose of radiation used also makes this case unique among reports of neuromuscular complications from radiation therapy. The patient is a 65-year-old male with node negative, high-grade adenocarcinoma of the rectum penetrating through the distal rectal wall. He underwent neoadjuvant concurrent pelvic radiation therapy and capecitabine-based chemotherapy, followed by abdominoperineal resection and post-operative FOLFOX chemotherapy. Five months post-completion of pelvic radiotherapy and 2 months after the completion of adjuvant chemotherapy, he presented with bilateral weakness of the iliopsoas muscles and severe pain radiating to the groin. The patient improved with 40 mg/d of prednisone, which was gradually tapered to 2 mg/d over 6 months, with substantial recovery of muscle strength and elimination of pain. The timing, presentation and response of our patient's symptoms to corticosteroids are most consistent with a radiation recall reaction. Radiation recall is a phenomenon whereby previously irradiated tissue becomes vulnerable to toxicity by subsequent systemic therapy and is rarely associated with myopathies. Radiation recall should be considered a potential complication of neoadjuvant radiation therapy for rectal cancer, and for ongoing research into the optimization of treatment for these patients. Severe myopathies caused by radiation recall may be fully reversible with corticosteroid treatment.

Central venous access devices in fluoropyrimidine therapy are associated with complications; however, reliable data are lacking regarding their natural history, associated complications and infusion pump performance in patients with metastatic colorectal cancer. We assessed device placement, use during treatment, associated clinical outcomes and infusion pump performance in the NO16966 trial. Device replacement was more common with FOLFOX-4 (5-fluorouracil (5-FU)+oxaliplatin) than XELOX (capecitabine+oxaliplatin) (14.1% vs 5.1%). Baseline device-associated events and post-baseline removal-/placement-related events occurred more frequently with FOLFOX-4 than XELOX (11.5% vs 2.4% and 8.5% vs 2.1%). Pump malfunctions, primarily infusion accelerations in 16% of patients, occurred within 1.6-4.3% of cycles. Fluoropyrimidine-associated grade 3/4 toxicity was increased in FOLFOX-4-treated patients experiencing a malfunction compared with those who did not (97 out of 155 vs 452 out of 825 patients), predominantly with increased grade 3/4 neutropenia (53.5% vs 39.8%). Febrile neutropenia rates were comparable between patient cohorts±malfunction. Efficacy outcomes were similar in patient cohorts±malfunction. Central venous access device removal or replacement was common and more frequent in patients receiving FOLFOX-4. Pump malfunctions were also common and were associated with increased rates of grade 3/4 haematological adverse events. Oral fluoropyrimidine-based regimens may be preferable to infusional 5-FU based on these findings.

Quality of Life Outcomes From a Phase 2 Trial of Short-Course Radiation Therapy Followed by FOLFOX Chemotherapy as Preoperative Treatment for Rectal Cancer

Khwaja, Shariq S.; Roy, Amit; Markovina, Stephanie

Purpose: A prospective phase 2 trial of short-course (SC) radiation therapy (RT) with 25 Gy over 5 fractions, followed by 4 cycles of 5-fluorouracil, oxaliplatin, and leucovorin (mFOLFOX6) before surgery was recently completed at our institution. We present here the patient-reported quality of life (QOL) outcomes from this trial. Methods and Materials: Eighty patients with cT3/T4, any N, any M rectal adenocarcinoma planned for resection were enrolled between 2009 and 2012. The QOL data were obtained prospectively using the Functional Assessment of Cancer Therapy-Colon (FACT-C) questionnaire before RT, before surgery, and 1 year after surgery. The previously validated minimally importance difference (MID)more » method was used to measure clinically significant QOL changes in FACT-C scores for each patient across time points. We examined the role of ostomy on QOL. We also compared QOL with disease outcomes and physician-reported toxicity. Results: The FACT-C questionnaire was completed by 97% of patients before RT, 85% immediately before surgery, and 62% 1 year after surgery. There was no statistically significant change in mean FACT-C scores from before treatment to after treatment. The majority of patients had either no change or an increase in QOL 1 year after treatment using the MID method. There were significant changes in QOL between patients with ostomy versus no ostomy 1 year after treatment for functional well-being (FWB) (14.81 vs 20.52, P=.018) and the colorectal cancer subscale (CCS) using the MID method (P=.004). Patients without ostomy reported stable changes in bowel control 1 year after surgery. There was no statistically significant correlation between QOL and disease recurrence, pathologic complete response, pathologic T stage downstaging, or acute/late toxicity. Conclusions: SC-RT and sequential mFOLFOX6 as preoperative therapy for rectal cancer results in stable patient-reported QOL outcomes 1 year after treatment. These findings in conjunction with previously reported oncologic outcomes support further evaluation of this regimen in a phase 3 setting.« less

In this report, we update survival (OS) and time-to-progression (TTP) data for the Intergroup trial N9741 after a median 5 years of follow-up by using risk-stratified and prognostic factor analyses to determine if treatment outcomes differ in specific patient subgroups. A total of 1,691 patients were randomly assigned to one of seven fluorouracil-, oxaliplatin-, and irinotecan-containing regimens. OS and TTP were calculated by treatment arm and baseline risk group (on the basis of WBC, performance status, number of sites of disease, and alkaline phosphatase). Multivariate prognostic factor analysis was used to assess clinical factors for their relationships to OS, TTP, response, and toxicity by using Cox and logistic regression models. The observed 5-year survival with infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX) of 9.8% was better than with irinotecan plus bolus fluorouracil and leucovorin (IFL; 3.7%; P = .04) or with bolus irinotecan/oxaliplatin (IROX; 5.1%; P = .128). OS and TTP were significantly longer for FOLFOX (20.2 months and 8.9 months, respectively) than for IFL (14.6 months and 6.1 months, respectively; P < .001 for both) or for IROX (17.3 months and 6.7 months, respectively; P < .001 for both). OS differed by risk group: 20.7 months for low risk, 17.4 months for intermediate risk, and 9.4 months for high risk (P < .001). FOLFOX treatment was superior in all risk groups and was the most powerful prognostic factor for OS, TTP, response rate, and toxicity. The 9.8% 5-year OS in patients with metastatic colorectal cancer who were treated with first-line FOLFOX sets a new benchmark. Neither baseline risk group nor any prognostic factor examined was predictive of treatment-specific outcome. However, treatment efficacy and patient longevity varied as a function of risk group.

Cetuximab (Cetux)/Bevacizumab (Bev) treatments have shown considerably survival benefits for patients with metastatic colorectal cancer (mCRC) in the last decade. But they are costly. Currently, no data is available on the health economic implications of testing for extended RAS wild-type (wt) prior to Cetux/Bev treatments of patients with mCRC. This paper aimed to evaluate the cost-effectiveness of predictive testing for extended RAS-wt status in mCRC in the context of targeting the use of Cetux/Bev.Markov model 1 was conducted to provide evidence evaluating the cost-effectiveness of predictive testing for KRAS-wt or extended RAS-wt status based on treatments of chemotherapy plus Cetux/Bev. Markov model 2 assessed the cost-effectiveness of FOLFOX plus Cetux/Bev or FOLFIRI plus Cetux/Bev in extended RAS-wt population. Primary base case data were identified from the CALGB 80405 trial and the literatures. Costs were estimated from West China Hospital, Sichuan University, China. Survival benefits were reported in quality-adjusted life-years (QALYs). The incremental cost-effectiveness ratio (ICER) was calculated.In analysis 1, the cost per QALY was $88,394.09 for KRAS-Cetux, $80,797.82 for KRAS-Bev, $82,590.72 for RAS-Cetux, and $75,358.42 for RAS-Bev. The ICER for RAS-Cetux versus RAS-Bev was $420,700.50 per QALY gained. In analysis 2, the cost per QALY was $81,572.61, $80,856.50, $80,592.22, and $66,794.96 for FOLFOX-Cetux, FOLFOX-Bev, FOLFIRI-Cetux, and FOLFIRI-Bev, respectively. The analyses showed that the extended RAS-wt testing was less costly and more effective versus KRAS-wt testing before chemotherapy plus Cetux/Bev. Furthermore, FOLFIRI plus Bev was the most cost-effective strategy compared with others in extended RAS-wt population.It was economically favorable to identify patients with extended RAS-wt status. Furthermore, FOLFIRI plus Bev was the preferred strategy in extended RAS-wt patients.

Standard therapy for advanced small bowel adenocarcinoma (SBA) has not yet been established. The present study assessed the efficacy and safety of chemotherapy (CT) in association with molecular targeting approaches for SBA. The histories of 33 advanced SBA patients from six different institutions in Japan, who received CT from 2008 to 2016, were retrospectively examined for background, clinical course and outcome. Median patient age was 65 years (range 39-83). Primary tumor was located in the duodenum in 21 patients (67%), the ampulla of Vater in three patients (9%), the jejunum in seven patients (21%) and the ileum in one patient (3%). Histologically, well-to-moderately and poorly differentiated adenocarcinoma were identified in 20 (61%) and nine (27%) patients, respectively. Thirteen patients received a single CT regimen, seven patients received two types of CT regimen, and 13 patients received three or more CT regimens. As first-line CT, modified FOLFOX6, capecitabine plus oxaliplatin, and S-1 plus cisplatin were employed in 13, 1, and 4 patients, respectively. The response rate (RR) and median progression-free survival (PFS) were 25% and 6.0 months, respectively. Median overall survival (OS) was 13.0 months. Nine out of the 33 patients received bevacizumab-containing CT and three received cetuximab-containing CT. Median OS of bevacizumab-containing CT patients was 21.9 months. No unexpected serious adverse events were observed. The analysis indicates that combination CT for advanced SBA is associated with modest efficacy and safety, and bevacizumab-containing CT may contribute to favorable outcome in these patients.

The CpG island methylator phenotype (CIMP) with multiple promoter methylated loci has been observed in a subset of human colorectal cancer (CRC) cases. CIMP status, which is closely associated with specific clinicopathological and molecular characteristics, is considered a potential predictive biomarker for efficacy of cancer treatment. However, the relationship between the effect of standard chemotherapy, including cytotoxic drugs and anti-epidermal growth factor receptor (EGFR) antibodies, and CIMP status has not been elucidated. In 125 metastatic colorectal cancer (mCRC) patients, we investigated how clinical outcome of chemotherapy was related to CIMP status as detected by methylation-specific PCR (MSP) and to genetic status in five EGFR-related genes (KRAS, BRAF, PIK3CA, NRAS, and AKT1) as detected by direct sequencing. CIMP-positive status was significantly associated with proximal tumor location and peritoneum metastasis (all P values <0.05). The progression-free survival of patients with CIMP-positive tumors receiving sequential therapy with FOLFOX as the first-line treatment followed by irinotecan-based therapy as the second-line treatment (median = 6.6 months) was inferior to that of such patients receiving the reverse sequence (median = 15.2 months; P = 0.043). Furthermore, CIMP-positive tumors showed higher mutation frequencies for the five EGFR-related genes (74.1 %) than the CIMP-negative tumors did (50.0 %). Among the KRAS wild-type tumors, CIMP-positive tumors were associated with a worse clinical outcome than CIMP-negative tumors following anti-EGFR antibody therapy. Sequential FOLFOX followed by an irinotecan-based regimen is unfavorable in patients with CIMP-positive tumors. High frequencies of mutation in EGFR-related genes in CIMP-positive tumors may cause the lower response to anti-EGFR antibody therapy seen in patients with wild-type KRAS and CIMP-positive tumors.

Background Six months of oxaliplatin-based chemotherapy is the standard adjuvant chemotherapy for completely resected stage III colorectal cancer (CRC). Also, patients with stage II CRC who are considered to be at high risk of disease recurrence often receive the same adjuvant chemotherapy treatment. We prospectively investigated the extent and degree of neuropathy suffered by stage III and high-risk stage II resectable CRC patients who underwent sequential approach involving 3 months of an oxaliplatin-based regimen followed by 3 months of capecitabine. Patients and methods Patients with completely resected stage III and high-risk stage II CRC aged ≥20 years were eligible. Patients were treated with folinic acid, fluorouracil, and oxaliplatin (FOLFOX) or capecitabine and oxaliplatin (CAPOX) for 3 months followed by capecitabine (2,500 mg/m2 on days 1–14 every 3 weeks) for 3 months. Primary end points were frequency and the grade of oxaliplatin-induced neurotoxicity as evaluated using the physician-based Common Terminology Criteria for Adverse Events version 4.0 (CTCAE) grading and the patient-based scale, self-reported Patient Neurotoxicity Questionnaire. Results Ninety-one patients were enrolled and 86 patients assessed. Eighty-four percent of patients completed the planned oxaliplatin-based therapy for 3 months, and 63% of patients completed all treatments for the full 6 months. Overall incidences of grade 3 or 4 peripheral sensory or motor neuropathy according to the CTCAE were 3.5% and 1.2%, respectively. Regarding the peripheral sensory neuropathy, the proportion of Patient Neurotoxicity Questionnaire (grade C–E) and CTCAE (grade 2–4) at months 1.5/3/6 were 11.3/22.1/29.4% and 5.3/4.4/11.3%, respectively (Spearman correlation coefficient: 0.47). Conclusion A sequential approach to adjuvant chemotherapy with 3 months of an oxaliplatin-based regimen followed by 3 months of capecitabine was tolerated by patients and associated with a low incidence of neuropathy.

A recent prospective randomised trial did not reveal significant differences in median progression-free survival between two chemoradiotherapy (CRT) regimens for inoperable non-metastatic oesophageal cancer patients. This secondary analysis aimed to describe the impact of CRT on health-related quality of life (HRQOL), physical functioning, dysphagia, fatigue and pain and to evaluate whether baseline HRQOL domains can predict overall survival. A total of 267 patients were randomly assigned to receive with 50 Gy of radiotherapy in 25 fractions six cycles of FOLFOX or four cycles of fluorouracil and cisplatin on day 1. HRQOL was prospectively assessed using the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire version 3.0 with the oesophageal cancer module (QLQ-OES18). Both groups showed high baseline compliance. Subsequently, compliance reduced to 41% at the 6-month follow-up. Baseline HRQOL scores showed no statistical differences between treatment arms. During treatment, both groups exhibited lower physical and social functioning and increased fatigue and dyspnoea, although dysphagia moderately improved in the fluorouracil-cisplatin arm only (p = 0.047). During follow-up, HRQOL scores revealed no significant differences between chemotherapy regimens. Linear mixed model exhibited a treatment-by-time interaction effect for dysphagia (p = 0.017) with a greater decrease in dysphagia in the fluorouracil-cisplatin group. Time until definitive deterioration analysis showed no significant differences in global HRQOL, functional or main symptom domains. However, time until definitive deterioration was significantly longer for the fluorouracil and cisplatin arm compared with FOLFOX for appetite loss (p = 0.002), QLQ-OES-18 pain (p = 0.008), trouble swallowing saliva (p = 0.011) and trouble talking (p = 0.020). Analyses of HRQOL scores revealed no statistically significant differences between patients with inoperable non-metastatic oesophageal cancer treated by FOLFOX versus those treated with a fluorouracil-cisplatin regimen as part of definitive CRT.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hong, Theodore S., E-mail: tshong1@mgh.harvard.edu; Moughan, Jennifer; Garofalo, Michael C.

Purpose: To evaluate the rate of gastrointestinal (GI) toxicity of neoadjuvant chemoradiation with capecitabine, oxaliplatin, and intensity modulated radiation therapy (IMRT) in cT3-4 rectal cancer. Methods and Materials: Patients with localized, nonmetastatic T3 or T4 rectal cancer <12 cm from the anal verge were enrolled in a prospective, multi-institutional, single-arm study of preoperative chemoradiation. Patients received 45 Gy with IMRT in 25 fractions, followed by a 3-dimensional conformal boost of 5.4 Gy in 3 fractions with concurrent capecitabine/oxaliplatin (CAPOX). Surgery was performed 4 to 8 weeks after the completion of therapy. Patients were recommended to receive FOLFOX chemotherapy after surgery. The primary endpoint ofmore » the study was acute grade 2 to 5 GI toxicity. Seventy-one patients provided 80% probability to detect at least a 12% reduction in the specified GI toxicity with the treatment of CAPOX and IMRT, at a significance level of .10 (1-sided). Results: Seventy-nine patients were accrued, of whom 68 were evaluable. Sixty-one patients (89.7%) had cT3 disease, and 37 (54.4%) had cN (+) disease. Postoperative chemotherapy was given to 42 of 68 patients. Fifty-eight patients had target contours drawn per protocol, 5 patients with acceptable variation, and 5 patients with unacceptable variations. Thirty-five patients (51.5%) experienced grade ≥2 GI toxicity, 12 patients (17.6%) experienced grade 3 or 4 diarrhea, and pCR was achieved in 10 patients (14.7%). With a median follow-up time of 3.98 years, the 4-year rate of locoregional failure was 7.4% (95% confidence interval [CI]: 1.0%-13.7%). The 4-year rates of OS and DFS were 82.9% (95% CI: 70.1%-90.6%) and 60.6% (95% CI: 47.5%-71.4%), respectively. Conclusion: The use of IMRT in neoadjuvant chemoradiation for rectal cancer did not reduce the rate of GI toxicity.« less

A randomized phase II/III trial was started in May 2015 comparing perioperative versus postoperative chemotherapy with modified infusional fluorouracil and folinic acid with oxaliplatin for lower rectal cancer patients with suspected lateral pelvic node metastasis. The standard arm is total mesorectal excision or tumor-specific mesorectal excision with lateral pelvic node dissection (LND) followed by postoperative chemotherapy (modified infusional fluorouracil and folinic acid with oxaliplatin; 12 cycles). The experimental (perioperative chemotherapy) arm is six courses of modified infusional fluorouracil and folinic acid with oxaliplatin before and six courses after total mesorectal excision with lateral pelvic node dissection. The aim of this trial is to confirm the superiority of perioperative chemotherapy. A total of 330 patients will be enrolled over 7 years. The primary endpoint in Phase II part is proportion of R0 resection and that in Phase III part is overall survival. Secondary endpoints are progression-free survival, local progression-free survival, etc. This trial has been registered in the UMIN Clinical Trials Registry as UMIN000017603 [http://www.umin.ac.jp/ctr/index-j.htm]. © The Author 2016.

The 5-year oncologic outcomes from the trial regimen were excellent. However, the neoadjuvant and surgical toxicity of this regimen was significant and was the primary reason for the low compliance with adjuvant systemic therapy.Due to the lack of an improvement in the pathologic complete response rate, the substantial associated toxicity, and the negative phase III trials of adjuvant bevacizumab in colon cancer, this regimen will not be pursued for further study. The addition of bevacizumab to chemotherapy improves overall survival for metastatic colorectal cancer. We initiated a phase II trial to evaluate preoperative capecitabine, oxaliplatin, and bevacizumab with radiation therapy (RT) followed by surgery and postoperative 5-fluorouracil, leucovorin, oxaliplatin (FOLFOX), and bevacizumab for locally advanced rectal cancer. The purpose of this report is to describe the 5-year oncologic outcomes of this regimen. In a phase II Simon two-stage design study, we evaluated preoperative treatment with capecitabine (825 mg/m(2) b.i.d. Monday-Friday), oxaliplatin (50 mg/m(2) weekly), bevacizumab (5 mg/kg on days 1, 15, and 29), and RT (50.4 Gy). Surgery was performed by 8 weeks after RT. Beginning 8-12 weeks after surgery, patients received FOLFOX plus bevacizumab (5 mg/kg) every 2 weeks for 12 cycles (oxaliplatin stopped after 9 cycles). The primary endpoint was a pathologic complete response (path-CR) rate of 30%. Fifty-seven patients with resectable T3/T4 rectal adenocarcinoma were enrolled between 2006 and 2010. Of 57 enrolled patients, 53 were eligible and included in the analysis. Forty-eight (91%) patients completed preoperative therapy, all of whom underwent curative surgical resection. Nine patients (17%) achieved path-CR. There were 29 worst grade 3 events, 8 worst grade 4 events, and 2 patient deaths, 1 of which was attributed to study therapy. Twenty-six patients (54%) began adjuvant chemotherapy. After a median follow-up period of 41 months, the 5-year overall survival (OS) rate for all patients was 80%. Only 2 patients experienced cancer recurrence: 1 distant (liver) and 1 loco-regional (pelvic lymph nodes), respectively. Both of these patients are still alive. The 5-year relapse-free survival rate was 81%. Despite the path-CR primary endpoint of this trial not being reached, the 5-year OS and recurrence-free survival rates were excellent. However, the neoadjuvant and surgical toxicity of this regimen was significant and was the primary reason for the low compliance with adjuvant systemic therapy. Because of the lack of an improvement in the path-CR rate, the substantial associated toxicity, and the negative phase III trials of adjuvant bevacizumab in colon cancer, this regimen will not be pursued for further study. ©AlphaMed Press; the data published online to support this summary is the property of the authors.

BACKGROUND The feasibility of additional dissection of the lateral pelvic lymph nodes (LPLNs) in patients undergoing total mesorectal excision (TME) combined with neoadjuvant chemotherapy (NAC) for locally advanced rectal cancer (LARC) is controversial. The use of laparoscopic surgery is also debated. In the present study, we evaluated the utility of laparoscopic dissection of LPLNs during TME for patients with LARC and metastatic LPLNs after NAC, based on our experience with 19 cases. MATERIAL AND METHODS Twenty-five patients with LARC with swollen LPLNs who underwent laparoscopic TME and LPLN dissection were enrolled in this pilot study. The patients were divided into 2 groups: those patients with NAC (n=19) and without NAC (n=6). Our NAC regimen involved 4 to 6 courses of FOLFOX plus panitumumab, cetuximab, or bevacizumab. RESULTS The operative duration was significantly longer in the NAC group than in the non-NAC group (648 vs. 558 minutes, respectively; P=0.022). The rate of major complications, defined as grade ≥3 according to the Clavien-Dindo classification, was similar between the 2 groups (15.8% vs. 33.3%, respectively; P=0.4016). No conversion to conventional laparotomy occurred in either group. In the NAC group, a histopathological complete response was obtained in 2 patients (10.5%), and a nearly complete response (Tis N0 M0) was observed in one patient (5.3%). Although the operation time was prolonged in the NAC group, the other perioperative factors showed no differences between the 2 groups. CONCLUSIONS Laparoscopic LPLN dissection is feasible in patients with LARC and clinically swollen LPLNs, even after NAC.

A 66-year-old female presented with the main complaint of defecation trouble and abdominal distention. With diagnosis of rectal cancer, cSS, cN0, cH0, cP0, cM0 cStage II, Hartmann's operation with D3 lymph node dissection was performed and a para-aortic lymph node and a disseminated node near the primary tumor were resected. Histological examination showed moderately differentiated adenocarcinoma, pSS, pN3, pH0, pP1, pM1 (para-aortic lymph node, dissemination) fStage IV. After the operation, the patient received chemotherapy with FOLFIRI regimen. After 12 cycles of FOLFIRI regimen, computed tomography (CT) detected an 11 mm of liver metastasis in the postero-inferior segment of right hepatic lobe. With diagnosis of liver metastatic recurrence, we performed partial hepatectomy. Histological examination revealed moderately differentiated adenocarcinoma as a metastatic rectal cancer with cut end microscopically positive. After the second operation, the patient received chemotherapy with TS1 alone for 2 years. Ten months after the break, CT detected a 20 mm of para-aortic lymph node metastasis and a 10 mm of lymph node metastasis at the hepato-duodenal ligament. With diagnosis of lymph node metastatic recurrences, we performed lymph node dissection. Histological examination revealed moderately differentiated adenocarcinoma as metastatic rectal cancer in para-aortic and hepato-duodenal ligament areas. After the third operation, we started chemotherapy with modified FOLFOX6 regimen. After 2 cycles of modified FOLFOX6 regimen, due to the onset of neutropenia and liver dysfunction, we switched to capecitabine alone and continued it for 6 mo and then stopped. Eleven months after the break, CT detected two swelling 12 mm of lymph nodes at the left supraclavicular region. With diagnosis of Virchow lymph node metastatic recurrence, we started chemotherapy with capecitabine plus bevacizumab regimen. Due to the onset of neutropenia and hand foot syndrome (Grade 3), we managed to continue capecitabine administration with extension of interval period and dose reduction. After 2 years and 2 mo from starting capecitabine plus bevacizumab regimen, Virchow lymph nodes had slowly grown up to 17 mm. Because no recurrence had been detected besides Virchow lymph nodes for this follow up period, considering the side effects and quality of life, surgical resection was selected. We performed left supraclavicular lymph node dissection. Histological examination revealed moderately differentiated adenocarcinoma as a metastatic rectal cancer. After the fourth operation, the patient selected follow up without chemotherapy. Now we follow up her without recurrence and keep her quality of life high.

In patients with metastatic colon cancer, response to first line chemotherapy is a strong predictor of overall survival (OS). Currently, oncologists lack diagnostic tests to determine which chemotherapy regimen offers the greatest chance for response in an individual patient. Here we present the results of gene expression analysis for two genes, ERCC1 and TS, measured with the commercially available ResponseDX: Colon assay (Response Genetics, Los Angeles, CA) in 41 patients with de novo metastatic colon cancer diagnosed between July 2008 and August 2013 at the University of California, San Diego. In addition ERCC1 and TS expression levels as determined by RNAseq and survival data for patients in TCGA were downloaded from the TCGA data portal. We found that patients with low expression of ERCC1 (n = 33) had significantly longer median OS (36.0 vs. 10.1 mo, HR 0.29, 95% CI .095 to .84, log-rank p = 9.0x10-6) and median time to treatment to failure (TTF) following first line chemotherapy (14.1 vs. 2.4 mo, HR 0.17, 95% CI 0.048 to 0.58, log-rank p = 5.3x10-4) relative to those with high expression (n = 4). After accounting for the covariates age, sex, tumor grade and ECOG performance status in a Cox proportional hazard model the association of low ERCC1 with longer OS (HR 0.18, 95% CI 0.14 to 0.26, p = 0.0448) and TTF (HR 0.16, 95% CI 0.14 to 0.21, p = 0.0053) remained significant. Patients with low TS expression (n = 29) had significantly longer median OS (36.0 vs. 14.8 mo, HR 0.25, 95% CI 0.074 to 0.82, log-rank p = 0.022) relative to those with high expression (n = 12). The combined low expression of ERCC1/TS was predictive of response in patients treated with FOLFOX (40% vs. 91%, RR 2.3, Fisher's exact test p = 0.03, n = 27), but not with FOLFIRI (71% vs. 71%, RR 1.0, Fisher's exact test p = 1, n = 14). Overall, these findings suggest that measurement of ERCC1 and TS expression has potential clinical utility in managing patients with metastatic colorectal cancer.

We describe a case of primary acinar cell carcinoma (ACC) originating in the liver in a 54-year-old female, diagnosed following persistent abnormal elevated liver function. Imaging revealed two masses, one dominant lesion in the right hepatic lobe and another in segment IVA. A right hepatectomy was performed to remove the larger lesion, while the mass in segment IVA was unresectable due to its proximity to the left hepatic vein. Immunohistochemical staining showed positivity for trypsin and chymotrypsin. Postoperatively the patient underwent hepatic arterial embolization of the other unresectable lesion followed by FOLFOX chemotherapy. At 20 months from diagnosis the patient is currently under observation with a decreasing necrotic mass and no other disease evident. Based on histology, immunohistochemistry and radiological findings a diagnosis of primary ACC of the liver was made. Genomic assessment of somatic mutations within the patient’s tumor was also performed through next generation sequencing and findings were consistent with an acinar malignancy. This case highlights a rare tumor subtype treated with a combination of therapeutic modalities through a multidisciplinary approach. PMID:29184698

Pharmacoeconomic assessments are a part of the decision process not only during reimbursement setting, but in clinical practice as well. The presented cost-effectiveness analysis assesses panitumumab+mFOLFOX6 vs. bevacizumab+mFOLFOX6 in 1st line treatment of patients with wildtype RAS metastatic colorectal cancer (mCRC) in the Czech environment. The adaptation of a Markov model considers the healthcare perspective; clinical data (efficacy, healthcare utilization and adverse events) are derived from a head-to-head comparison (PEAK study). Health states included in the model: progression free on treatment, progression (with/ without active treatment), resection of metastases, disease-free after successful resection and death. Actual reimbursement levels were used to estimate costs, published literature to estimate duration of 2nd line treatment. The analysis assumes a lifetime horizon; uncertainty was limited by performing one-way and probabilistic sensitivity analyses. Analysis outcomes are life-years gained (LYG) and quality-adjusted life-years (QALYs). Panitumumab+mFOLFOX6 is more effective and more costly in 1st line patients with wildtype RAS mCRC. Incremental costs per QALY are 837,270 CZK, per LYG 615,022 CZK; however, below the willingness-to-pay threshold applied in the Czech Republic. Panitumumab+mFOLFOX6 is cost-effective in 1st line treatment of patients with wildtype RAS mCRC compared to bevacizumab+mFOLFOX6 in the Czech setting.

The Hippo pathway is involved in colorectal cancer (CRC) development and progression. The Hippo regulator Rassf1a is also involved in the Ras signaling cascade. In this work, we tested single nucleotide polymorphisms within Hippo components and their association with outcome in CRC patients treated with cetuximab. Two cohorts treated with cetuximab plus chemotherapy were evaluated (198 RAS wild-type (WT) patients treated with first-line FOLFIRI plus Cetuximab within the FIRE-3 trial and 67 Ras WT patients treated either with first-line mFOLFOX6 or SOX plus Cetuximab). In these two populations, Rassf1a rs2236947 was associated with overall survival (OS), as patients with a CC genotype had significantly longer OS compared with those with CA or AA genotypes. This association was stronger in patients with left-side CRC (hazard ratio (HR): 1.79 (1.01-3.14); P=0.044 and HR: 2.83 (1.14-7.03); P=0.025, for Fire 3 and JACCRO cohorts, respectively). Rassf1a rs2236947 is a promising biomarker for patients treated with cetuximab plus chemotherapy.

A 74-year-old male had undergone laparoscopic abdominoperineal resection for lower rectal cancer in July 2009. The pathological diagnosis was T2, N0, M0, pStage I (TNM 7th). Because of pathological venous invasion, adjuvant chemotherapy with Tegafur-uracil(UFT)plus Leucovorin for a year was performed. A CT examination revealed slowly growing peripheral right internal iliaclymph node. PET-CT demonstrated a 20mm right lateral lymph node(LLN)metastasis without other distant metastases. On diagnosis of solitary LLN metastasis of rectal cancer, the patient underwent surgical lymph node resection in September 2014. The pathological diagnosis was lymph node metastasis from rectal cancer. Subsequently, the patient received mFOLFOX6 adjuvant chemotherapy for 6 months. The patient remains alive without any recurrence 31 months after the second surgical treatment. lt is important to consider that LLN metastasis of Stage I rectal cancer might still occur a long time after the curative operation.

Improvements in local control are required when using preoperative chemoradiation for cT4 or advanced cT3 rectal cancer. There is therefore a need to explore more effective schedules. Patients with fixed cT3 or cT4 cancer were randomized either to 5 × 5 Gy and three cycles of FOLFOX4 (group A) or to 50.4 Gy in 28 fractions combined with two 5-day cycles of bolus 5-Fu 325 mg/m(2)/day and leucovorin 20 mg/m(2)/day during the first and fifth week of irradiation along with five infusions of oxaliplatin 50 mg/m(2) once weekly (group B). The protocol was amended in 2012 to allow oxaliplatin to be then foregone in both groups. Of 541 entered patients, 515 were eligible for analysis; 261 in group A and 254 in group B. Preoperative treatment acute toxicity was lower in group A than group B, P = 0.006; any toxicity being, respectively, 75% versus 83%, grade III-IV 23% versus 21% and toxic deaths 1% versus 3%. R0 resection rates (primary end point) and pathological complete response rates in groups A and B were, respectively, 77% versus 71%, P = 0.07, and 16% versus 12%, P = 0.17. The median follow-up was 35 months. At 3 years, the rates of overall survival and disease-free survival in groups A and B were, respectively, 73% versus 65%, P = 0.046, and 53% versus 52%, P = 0.85, together with the cumulative incidence of local failure and distant metastases being, respectively, 22% versus 21%, P = 0.82, and 30% versus 27%, P = 0.26. Postoperative and late complications rates in group A and group B were, respectively, 29% versus 25%, P = 0.18, and 20% versus 22%, P = 0.54. No differences were observed in local efficacy between 5 × 5 Gy with consolidation chemotherapy and long-course chemoradiation. Nevertheless, an improved overall survival and lower acute toxicity favours the 5 × 5 Gy schedule with consolidation chemotherapy.

The objective of this economic evaluation, which was based on patients from two randomized controlled clinical trials (NO16966 and NO16967), was to compare direct medical costs to the Australian health-care system of capecitabine plus oxaliplatin (XELOX) and bolus and/or infusional 5-fluorouracil (5-FU) plus folinic acid combined with oxaliplatin (modified [m] FOLFOX-6) in first-line and second-line treatment of advanced or metastatic colorectal cancer (mCRC). Direct medical costs were estimated for five treatment settings from a public and private hospital. The costs included in evaluation were for drug acquisition, preparation (oxaliplatin, bolus and infusional 5-FU), administration and wastage. The cost of drug acquisition was calculated based on dosage data and the mean number of treatment cycles from the pivotal studies NO16966 and NO16967. There were no costs associated with preparing capecitabine and leucovorin. An oncology grouping and costing study was performed to determine the relevant administration costs associated with central venous access devices, their placement, maintenance and removal (for oxaliplatin administration) and the continuous infusion of 5-FU via a continuous ambulatory delivery device pump or infuser. This economic evaluation has shown that treating mCRC patients with XELOX in the first and second-line settings results in average cost savings of $9110 and $7113, respectively, compared with mFOLFOX-6. A multi-way sensitivity analysis demonstrated that the use of XELOX remained cost-saving from an Australian government health budget perspective. The use of XELOX, compared with mFOLFOX-6, for the treatment of mCRC is cost-saving in the Australian government health budget. © 2012 Wiley Publishing Asia Pty Ltd.

Combination therapy with oral fluoropyrimidine and irinotecan has not yet been established as first-line treatment of metastatic colorectal cancer (mCRC). We carried out a randomized, open-label, phase III trial to determine whether S-1 and irinotecan plus bevacizumab is noninferior to mFOLFOX6 or CapeOX plus bevacizumab in terms of progression-free survival (PFS). Patients from 53 institutions who had previously untreated mCRC were randomly assigned (1 : 1) to receive either mFOLFOX6 or CapeOX plus bevacizumab (control group) or S-1 and irinotecan plus bevacizumab (experimental group; a 3-week regimen: intravenous infusions of irinotecan 150 mg/m2 and bevacizumab 7.5 mg/kg on day 1, oral S-1 80 mg/m2 twice daily for 2 weeks, followed by a 1-week rest; or a 4-week regimen: irinotecan 100 mg/m2 and bevacizumab 5 mg/kg on days 1 and 15, S-1 80 mg/m2 twice daily for 2 weeks, followed by a 2-week rest). The primary end point was PFS. The noninferiority margin was 1.25; noninferiority would be established if the upper limit of the 95% confidence interval (CI) for the hazard ratio (HR) of the control group versus the experimental group was less than this margin. Between June 2012 and September 2014, 487 patients underwent randomization. Two hundred and forty-three patients assigned to the control group and 241 assigned to the experimental group were included in the primary analysis. Median PFS was 10.8 months (95% CI 9.6-11.6) in the control group and 14.0 months (95% CI 12.4-15.5) in the experimental group (HR 0.84, 95% CI 0.70-1.02; P < 0.0001 for noninferiority, P = 0.0815 for superiority). One hundred and fifty-seven patients (64.9%) in the control group and 140 (58.6%) in the experimental group had adverse events of grade 3 or higher. S-1 and irinotecan plus bevacizumab is noninferior to mFOLFOX6 or CapeOX plus bevacizumab with respect to PFS as first-line treatment of mCRC and could be a new standard treatment. UMIN000007834.

To investigate the cost-effectiveness of panitumumab plus mFOLFOX6 (oxaliplatin, 5-fluorouracil and leucovorin) compared with bevacizumab plus mFOLFOX6 in first-line treatment of patients with wild-type RAS metastatic colorectal cancer (mCRC). A semi-Markov model was constructed from a French health collective perspective, with health states related to first-line treatment (progression-free), disease progression with and without subsequent active treatment, resection of metastases, disease-free after successful resection and death. Parametric survival analyses of patient-level progression-free and overall survival data from the only head-to-head clinical trial of panitumumab and bevacizumab (PEAK) were performed to estimate transitions to disease progression and death. Additional data from PEAK informed the amount of each drug consumed, duration of therapy, subsequent therapy use, and toxicities related to mCRC treatment. Literature and French public data sources were used to estimate unit costs associated with treatment and duration of subsequent active therapies. Utility weights were calculated from patient-level data from panitumumab trials in the first-, second- and third-line settings. A life-time perspective was applied. Scenario, one-way, and probabilistic sensitivity analyses were performed. Based on a head-to-head clinical trial that demonstrates better efficacy outcomes for patients with wild-type RAS mCRC who receive panitumumab plus mFOLFOX6 versus bevacizumab plus mFOLFOX6, the incremental cost per life-year gained was estimated to be €26,918, and the incremental cost per quality-adjusted life year (QALY) gained was estimated to be €36,577. Sensitivity analyses indicate the model is robust to alternative parameters and assumptions. The incremental cost per QALY gained indicates that panitumumab plus mFOLFOX6 represents good value for money in comparison to bevacizumab plus mFOLFOX6 and, with a willingness-to-pay ranging from €40,000 to €60,000, can be considered cost-effective in first-line treatment of patients with wild-type RAS mCRC.

A phase ΙI study of five peptides combination with oxaliplatin-based chemotherapy as a first-line therapy for advanced colorectal cancer (FXV study)

PubMed Central

2014-01-01

Background We previously conducted a phase I trial for advanced colorectal cancer (CRC) using five HLA-A*2402-restricted peptides, three derived from oncoantigens and two from vascular endothelial growth factor (VEGF) receptors, and confirmed safety and immunological responses. To evaluate clinical benefits of cancer vaccination treatment, we conducted a phase II trial using the same peptides in combination with oxaliplatin-based chemotherapy as a first-line therapy. Methods The primary objective of the study was the response rates (RR). Progression free survival (PFS), overall survival (OS), and immunological parameters were evaluated as secondary objective. The planned sample size was more than 40 patients for both HLA2402-matched and -unmatched groups. All patients received a cocktail of five peptides (3 mg each) mixed with 1.5 ml of IFA which was subcutaneously administered weekly for the first 12 weeks followed by biweekly administration. Presence or absence of the HLA-A*2402 genotype were used for classification of patients into two groups. Results Between February 2009 and November 2012, ninety-six chemotherapy naïve CRC patients were enrolled under the masking of their HLA-A status. Ninety-three patients received mFOLFOX6 and three received XELOX. Bevacizumab was added in five patients. RR was 62.0% and 60.9% in the HLA-A*2402-matched and -unmatched groups, respectively (p = 0.910). The median OS was 20.7 months in the HLA-A*2402-matched group and 24.0 months in the unmatched group (log-rank, p = 0.489). In subgroup with a neutrophil/lymphocyte ratio (NLR) of < 3.0, patients in the HLA-matched group did not survive significantly longer than those in the unmatched group (log-rank, p = 0.289) but showed a delayed response. Conclusions Although no significance was observed for planned statistical efficacy endpoints, a delayed response was observed in subgroup with a NLR of < 3.0. Biomarkers such as NLR might be useful for selecting patients with a better treatment outcome by the vaccination. Trial registration Trial registration: UMIN000001791. PMID:24884643

In stage III colon cancer, oxaliplatin/5-fluorouracil (5-FU)-based adjuvant chemotherapy (FOLFOX) improves disease-free survival (DFS) and overall survival (OS). In rectal adenocarcinoma following neoadjuvant chemoradiation (CRT), we examined the benefit of postoperative adjuvant capecitabine and oxaliplatin (XELOX) chemotherapy. Eligible patients were randomly assigned following fluoropyrimidine-based CRT and curative resection to observation or six cycles of XELOX. The primary end point was DFS; secondary end points were acute toxicity and OS. 390 patients were required in each arm, to detect an improvement in 3-year DFS from 40% to 50.5%, with 85% power and two-sided 5% significance level. The study closed prematurely in 2008 because of poor accrual. Only 113 patients were randomly assigned to either observation (n = 59) or XELOX (n = 54). Compliance was poor, 93% allocated chemotherapy started and 48% completed six cycles. Protocolised dose reductions in XELOX were 39%, and levels of G3/G4 toxicity 40%. After a median follow-up of 44.8 months, 16 patients (27%) in the observation arm had relapsed or died compared with 12 patients (22%) in XELOX. The 3-year DFS rate was 78% with XELOX and 71% with observation [hazard ratio (HR) for DFS = 0.80; 95% confidence interval (CI) 0.38-1.69; P = 0.56]. The 3-year OS for XELOX and observation were 89% and 88%, respectively (HR for OS = 1.18; 95% CI 0.43-3.26; P = 0.75). The observed improvement in DFS for adjuvant XELOX and similar OS were not statistically significant, as expected given the small number of patients and consequent low power. Our findings support the need for trials that test the role of neoadjuvant chemotherapy. NCT00427713. © The Author 2014.

Zhao et al. investigated the association between germline genetic polymorphisms in DPYD, the gene encoding dihydropyrimidine dehydrogenase, and (1) the risk of developing pediatric acute lymphoblastic leukemia and (2) outcome of acute lymphoblastic leukemia following the treatment with 5-fluorouracil plus oxaliplatin (FOLFOX). The authors found that the common DPYD variant c.85T>C (rs1801265, DPYD*9A) was significantly associated with (1) risk of developing pediatric acute lymphoblastic leukemia, (2) complete response rate, (3) event-free survival, and (4) treatment-related toxicity. The authors conclude that patients carrying the c.85T>C C allele have an increased risk of developing acute lymphoblastic leukemia and have inferior outcome, and that DPYD c.85T>C can be used as a guide for individualized treatment and the decision to utilize 5-fluorouracil in acute lymphoblastic leukemia patients. In our view, the published article gives rise to multiple critical issues regarding the study's rationale and the methodology used, which strongly question the validity of the authors' conclusions.

The therapeutic management of people with metastatic colorectal cancer (CRC) who did not respond to first-line treatment represents a formidable challenge. To determine the efficacy and toxicity of second-line systemic therapy in people with metastatic CRC. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2016, Issue 4), Ovid MEDLINE (1950 to May 2016), Ovid MEDLINE In-process & Other Non-Indexed Citations (1946 to May 2016) and Ovid Embase (1974 to May 2016). There were no language or date of publication restrictions. Randomized controlled trials (RCTs) assessing the efficacy (survival, tumour response) and toxicity (incidence of severe adverse effects (SAEs)) of second-line systemic therapy (single or combined treatment with any anticancer drug, at any dose and number of cycles) in people with metastatic CRC that progressed, recurred or did not respond to first-line systemic therapy. Authors performed a descriptive analysis of each included RCT in terms of primary (survival) and secondary (tumour response, toxicity) endpoints. In the light of the variety of drug regimens tested in the included trials, we could carry out meta-analysis considering classes of (rather than single) anticancer regimens; to this aim, we applied the random-effects model to pool the data. We used hazard ratios (HRs) and risk ratios (RRs) to describe the strength of the association for survival (overall (OS) and progression-free survival (PFS)) and dichotomous (overall response rate (ORR) and SAE rate) data, respectively, with 95% confidence intervals (CI). Thirty-four RCTs (enrolling 13,787 participants) fulfilled the eligibility criteria. Available evidence enabled us to address multiple clinical issues regarding the survival effects of second-line systemic therapy of people with metastatic CRC.1. Chemotherapy (irinotecan) was more effective than best supportive care (HR for OS: 0.58, 95% CI 0.43 to 0.80; 1 RCT; moderate-quality evidence); 2. modern chemotherapy (FOLFOX (5-fluorouracil plus leucovorin plus oxaliplatin), irinotecan) is more effective than outdated chemotherapy (5-fluorouracil) (HR for PFS: 0.59, 95% CI 0.49 to 0.73; 2 RCTs; high-quality evidence) (HR for OS: 0.69, 95% CI 0.51 to 0.94; 1 RCT; moderate-quality evidence); 3. irinotecan-based combinations were more effective than irinotecan alone (HR for PFS: 0.68, 95% CI 0.60 to 0.76; 6 RCTs; moderate-quality evidence); 4. targeted agents improved the efficacy of conventional chemotherapy both when considered together (HR for OS: 0.84, 95% CI 0.77 to 0.91; 6 RCTs; high-quality evidence) and when bevacizumab was used alone (HR for PFS: 0.67, 95% CI 0.60 to 0.75; 4 RCTs; high-quality evidence).With regard to secondary endpoints, tumour response rates generally paralleled the survival results; moreover, higher anticancer efficacy was generally associated with worse treatment-related toxicity, with the important exception of bevacizumab-containing regimens, where the addition of the targeted agent to chemotherapy did not result in a significant increase in the rate of SAE. Finally, we found that oral (instead of intravenous) fluoropyrimidines significantly reduced the incidence of adverse effects (without compromising efficacy) in people treated with oxaliplatin-based regimens.We could not draw any conclusions on other debated aspects in this field of oncology, such as ranking of treatments (not all possible comparisons have been tested and many comparisons were based on single trials enrolling a small number of participants) and quality of life (virtually no data available). Systemic therapy offers a survival benefit to people with metastatic CRC who did not respond to first-line treatment, especially when targeted agents are combined with conventional chemotherapeutic drugs. Further research is needed to define the optimal regimen and to identify people who most benefit from each treatment.

Curcumin (diferuloylmethane), which has no discernible toxicity, inhibits initiation, promotion and progression of carcinogenesis. 5-Fluorouracil (5-FU) or 5-FU plus oxaliplatin (FOLFOX) remains the backbone of colorectal cancer chemotherapeutics, but produces an incomplete response resulting in survival of cells (chemo-surviving cells) that may lead to cancer recurrence. The present investigation was, therefore, undertaken to examine whether addition of curcumin to FOLFOX is a superior therapeutic strategy for chemo-surviving cells. Forty-eight-hour treatment of colon cancer HCT-116 and HT-29 cells with FOLFOX resulted in 60-70% survival, accompanied by a marked activation of insulin like growth factor-1 receptor (IGF-1R) and minor to moderate increase in epidermal growth factor receptor (EGFR), v-erb-b2 erythroblastic leukemia viral oncogene homolog 2 (HER-2) as well as v-akt murine thymoma viral oncogene homolog 1 (AKT), cyclooxygenase-2 (COX-2) and cyclin-D1. However, inclusion of curcumin to continued FOLFOX treatment for another 48 h greatly reduced the survival of these cells, accompanied by a concomitant reduction in activation of EGFR, HER-2, IGF-1R and AKT, as well as expression of COX-2 and cyclin-D1. More importantly, EGFR tyrosine kinase inhibitor gefitinib or attenuation of IGF-1R expression by the corresponding si-RNA caused a 30-60% growth inhibition of chemo-surviving HCT-116 cells. However, curcumin alone was found to be more effective than both gefitinib and IGF-1R si-RNA mediated growth inhibition of chemo-surviving HCT-116 cells and addition of FOLFOX to curcumin did not increase the growth inhibitory effect of curcumin. Our data suggest that inclusion of curcumin in conventional chemotherapeutic regimens could be an effective strategy to prevent the emergence of chemoresistant colon cancer cells.

The management of disappearing colorectal liver metastases in the postadjuvant chemotherapy setting is challenging. We describe a novel technique that facilitates laparoscopic resection of disappearing metastatic liver lesions with great precision. Details of this new technique are described in 2 patients with colorectal cancer synchronously metastatic to the liver. Both patients had small indistinct intraparenchymal liver lesions after adjuvant chemotherapy. A video displays the steps of the procedure. Both patients presented with colorectal cancer with synchronous liver metastasis. They received FOLFOX regimen after resection of their primary. They both responded to adjuvant chemotherapy. On repeat posttreatment imaging, the liver lesions became smaller and indistinct. With laparoscopic ultrasound, subtle parenchymal heterogeneities were identified. The lesions were initially ablated with a wide radiofrequency ablation zone. Then, without removing the needle, the prongs were deployed to the borders of the parenchymal heterogeneity. Using an ultrasonic vessel sealer, the lesions were resected. Final pathology identified 1 viable focus of cancer in each patient. Both patients were discharged home uneventfully on their second postoperative day. There were no complications. We have described a novel technique that could facilitate precise resection of intraparenchymal small indistinct or disappearing liver metastases of colorectal origin. This option should be kept within the armamentarium of the laparoscopic liver surgeon managing patients with malignant liver tumors.

Background: Dihydropyrimidine dehydrogenase (DPD) catabolises ∼85% of the administered dose of fluoropyrimidines. Functional DPYD gene variants cause reduced/abrogated DPD activity. DPYD variants analysis may help for defining individual patients’ risk of fluoropyrimidine-related severe toxicity. Methods: The TOSCA Italian randomised trial enrolled colon cancer patients for 3 or 6 months of either FOLFOX-4 or XELOX adjuvant chemotherapy. In an ancillary pharmacogenetic study, 10 DPYD variants (*2A rs3918290 G>A, *13 rs55886062 T>G, rs67376798 A>T, *4 rs1801158 G>A, *5 rs1801159 A>G, *6 rs1801160 G>A, *9A rs1801265 T>C, rs2297595 A>G, rs17376848 T>C, and rs75017182 C>G), were retrospectively tested for associations with ⩾grade 3 fluoropyrimidine-related adverse events (FAEs). An association analysis and a time-to-toxicity (TTT) analysis were planned. To adjust for multiple testing, the Benjamini and Hochberg’s False Discovery Rate (FDR) procedure was used. Results: FAEs occurred in 194 out of 508 assessable patients (38.2%). In the association analysis, FAEs occurred more frequently in *6 rs1801160 A allele carriers (FDR=0.0083). At multivariate TTT analysis, significant associations were found for *6 rs1801160 A allele carriers (FDR<0.0001), *2A rs3918290 A allele carriers (FDR<0.0001), and rs2297595 GG genotype carriers (FDR=0.0014). Neutropenia was the most common FAEs (28.5%). *6 rs1801160 (FDR<0.0001), and *2A rs3918290 (FDR=0.0004) variant alleles were significantly associated with time to neutropenia. Conclusions: This study adds evidence on the role of DPYD pharmacogenetics for safety of patients undergoing fluoropyrimidine-based chemotherapy. PMID:29065426

Different chemotherapy backbones may be chosen, including one to three drugs, based on patients' general conditions and comorbidities, treatments' objectives, and disease characteristics. TRIBE trial demonstrated a significant advantage in terms of progression-free survival and overall survival for FOLFOXIRI plus bevacizumab as compared with FOLFIRI plus bevacizumab. Based on recent evidence, the de-intensification of the upfront regimen after 4-6 months of treatment is nowadays regarded as a valuable option. Moreover, the prolonged inhibition of angiogenesis, and in particular the continuation of bevacizumab beyond the evidence of disease progression, is an efficacious strategy in the treatment of metastatic colorectal cancer patients. TRIBE-2 is a prospective, open-label, multicentric phase III randomized trial in which unresectable and previously untreated metastatic colorectal cancer patients are randomized to receive first-line FOLFOX plus bevacizumab followed by FOLFIRI plus bevacizumab after disease progression or FOLFOXIRI plus bevacizumab followed by the re-introduction of the same regimen after disease progression. The primary endpoint is to compare the efficacy of the two proposed treatment strategies in terms of Progression Free Survival 2. The TRIBE-2 study aims at answering the question whether the upfront use of FOLFOXIRI improves the clinical outcome of metastatic colorectal cancer patients, when compared with the pre-planned, sequential use of oxaliplatin-based and irinotecan-based doublets. Both proposed treatment strategies are designed to exploit the effectiveness of the prolonged inhibition of angiogenesis, alternating short (up to 4 months) induction periods and less intensive maintenance phases.

To evaluate the impact of targeted agents in stage II-III rectal cancer undergoing neoadjuvant concurrent chemoradiation therapy (CCRT). A retrospective study was performed in 124 consecutive patients with clinically T 3 N 0-2 M 0 -staged rectal cancer incorporating targeted agents in CCRT. Pathologic complete response was detected in 34.2% (n=26) of bevacizumab+FOLFOX-treated patients (n=76), which was significantly higher (p=0.019, post-hoc statistical power =35.87%) than that (n=10, 20.8%) of the cetuximab+FOLFOX-treated patients (n=48). Patients receiving cetuximab+FOLFOX therapy tended to develop severe liver toxicity (91.7%, n=44 versus 17.1%, n=13, p<0.0001), as evaluated by morphologic grading of hepatic steatosis and sinusoidal dilatation in laparoscopy. In the 57 patients with morphologically severe liver toxicity, 36 (63.2%) retained a normal liver function; for the remaining 21 patients with an abnormal liver function, the abnormality was self-limited in 19 patients, whereas 2 cetuximab-treated patients progressed to hepatic failure and mortality. A subset analysis within bevacizumab+FOLFOX-treated patients with either wild-type (n=36) or mutant (n=40) K-ras status indicated K-ras status did not significantly influence the treatment outcomes. The addition of bevacizumab instead of cetuximab to FOLFOX in the neoadjuvant settings for T 3 N 0-2 M 0 -staged rectal cancer could induce a promising rate of pathologic complete response and lesser hepatotoxicity.

We report a case of a 60-year-old woman with abdominal distension who was treated with self-expandable metal stent (SEMS) placement in the proximal transverse colon. She was found to have severe bowel obstruction due to advanced transverse colon cancer on plain computed tomography (CT) and colonoscopy. We performed colonic stenting safely, and the symptom promptly improved. Defecation and flatus were observed on the same day of stenting, and the patient was able to start drinking and eating on the next day. Enhanced abdominal CT revealed multiple liver metastasis, peritoneal dissemination, ascites, and cystic ovarian tumor. After treatment with 1 course of 5-fluorouracil, Leucovorin, and oxaliplatin (mFOLFOX6), the patient was discharged on day 14 after admission. The rapidly enlarging ovarian tumors and primary colonic lesion with SEMS were surgically removed after treatment with mFOLFOX6 for 4 months in an outpatient basis. The patient has been alive with a good quality of life (QOL) and being treated with bevacizumab plus mFOLFOX6/Leucovorin, 5-fluorouracil, and irinotecan( FOLFIRI) for 6 months. SEMS placement could be safe and effective for the treatment of obstruction of the right colon, and could maintain a good QOL in patients.

Patients with unresectable wild-type KRAS metastatic colorectal cancer benefit from fluoropyrimidines (FP), oxaliplatin (O), irinotecan (I), bevacizumab (Bev), and epithelial growth factor receptor inhibitors (EGFRI). The most cost-effective regimen remains unclear. A Markov model was constructed to examine the costs and outcomes of three treatment strategies: strategy A (reference strategy): EGFRI monotherapy in third line ([3L]; ie, first-line [1L]: Bev + FOLFIRI [FP + I] or FOLFOX [FP + O]; second line [2L]: FOLFIRI/FOLFOX; 3L: EGFRI); strategy B: EGFRI and I in 3L (ie, 1L: Bev + FOLFIRI/FOLFOX; 2L: FOLFIRI/FOLFOX; 3L: EGFRI + I); and strategy C: EGFRI in 1L (ie, 1L: EGFRI + FOLFIRI/FOLFOX; 2L: Bev + FOLFIRI/FOLFOX; 3L: best supportive care). Efficacy data of the treatments were obtained from the literature. Health system resource use information was derived from chart review and the literature. Using Euro-QOL 5 Dimensions, utilities were obtained by surveying medical oncologists and costs from the Ontario Ministry of Health and the literature. The perspective of the Canadian public health care system was used over a 5-year time horizon with a 5% discount in 2012 Canadian dollars. All three strategies had similar efficacy, but strategy C was most expensive. The incremental cost-effectiveness ratios (ICERs) for strategies B and C compared with A were 119,623 and 3,176,591, respectively. The model was primarily driven by the acquisition cost of the drugs. Strategy B was most cost effective when the willingness-to-pay threshold was > $130,000 per quality-adjusted life-year. Sensitivity analysis showed that strategy C would be cost-effective only when the progression-free survival of EGFRI is better than Bev in 1L with hazard ratio < 0.23 at willingness-to-pay of $150,000 per quality-adjusted life-year. First-line use of EGFRI in metastatic colorectal cancer is not cost effective at its current pricing relative to Bev. Copyright © 2016 by American Society of Clinical Oncology.

In advanced gastric cancer, doublet regimen including platinum salts and fluoropyrimidine is considered as a standard first-line treatment. The addition of docetaxel (75 mg/m 2  q3w) to cisplatin (75 mg/m 2  q3w) and 5-fluorouracil has been shown to improve efficacy. However, this regimen (DCF) was associated with frequent severe toxicities (including more complicated neutropenia), limiting its use in clinical practice. Interesting alternative docetaxel-based regimens have been developed that need to be validated. GASTFOX study is a randomized phase III trial comparing FOLFOX alone or with docetaxel at 50 mg/m 2 (TFOX regimen) in first-line treatment for advanced gastric cancer. In both arms, cycle is repeated every 2 weeks until disease progression or unacceptable toxicity. Main eligibility criteria: histologically proven locally advanced or metastatic gastric or esogastric junction adenocarcinoma, HER negative status, measurable disease, ECOG performance status 0 or 1, and adequate renal, hepatic and bone marrow functions. The primary endpoint is radiological/clinical progression-free survival (PFS). A difference of 2 months for the median PFS in favor of TFOX is expected (HR = 0.73) Based on a two-sided α risk of 5% and a power of 90%, 454 events are required to show this difference. Secondary endpoints included overall survival, overall response rate, safety, quality of life and the therapeutic index. This study is planned to include 506 patients to demonstrate the superiority of TFOX over FOLFOX in first-line advanced gastric cancer treatment (NCT03006432).

Platinum-based chemotherapy is the standard treatment for advanced urothelial cancer (UC) and is generally used in the first-line setting. However, the optimal salvage treatment for previously treated UC patients is unclear. We conducted a systematic review of published clinical trials of single agent versus combined chemotherapy as salvage treatment in previously treated UC patients. Trials published between 1994 and 2015 were identified by an electronic search of public databases (MEDLINE, EMBASE, Cochrane library). All relevant studies were independently identified by two authors for inclusion. Demographic data, treatment regimens, objective response rate (ORR), disease control rate (DCR), median progression-free and overall survival (PFS, OS), and grade 3/4 toxicities were extracted and analyzed using Comprehensive Meta Analysis software (Version 2.0). Fifty cohorts with 1,685 patients were included for analysis: 814 patients were treated with single agent chemotherapy and 871 with combined chemotherapy. Pooled OS was significantly higher at 1 year for combined chemotherapy than for single agent (relative risk [RR] 1.52; 95% CI: 1.01-2.37; P=0.03) but not for 2-year OS (RR 1.31; 95% CI: 0.92-1.85; P=0.064). Additionally, combined chemotherapy significantly improved ORR (RR 2.25; 95% CI: 1.60-3.18; P<0.001) and DCR (RR 1.12; 95% CI: 1.01-1.25, P=0.033) compared to single agent for advanced UC patients. As for grade 3 and 4 toxicities, more frequencies of leukopenia and thrombocytopenia were observed in the combined chemotherapy than in single agent group, while equivalent frequencies of anemia, nausea, vomiting, and diarrhea were found between the two groups. In comparison with single agent alone, combined chemotherapy as salvage treatment for advanced UC patients significantly improved ORR, DCR, and 1-year OS, but not 2-year OS. Our findings support the need to compare combined chemotherapy with single agent alone in the salvage setting in large prospective trials due to its potential survival benefit in advanced UC patients.

Turmeric is commonly used as a medicinal herb and dietary supplement. Its active ingredient, curcumin, has been shown to possess antitumor effects in colorectal cancer patients. However, poor absorption of curcumin in intestine impedes its wide clinical application. Our previous findings showed that the presence of turmerones increased the accumulation of curcumin inside colonic cells. Hence, we hypothesized that curcumin with turmerones or present in turmeric ethanolic extract would augment its anti-tumor activities in tumor-bearing mice. The pharmacokinetics of curcumin in different preparations (containing same amount of curcumin) were studied in mice. The anti-tumor efficacies of curcumin or turmeric extract (with absorbable curcumin) in combination with bevacizumab were further investigated in HT29 colon tumor-bearing mice. Pharmacokinetic results showed that the plasma curcumin level of turmeric extract-fed mice was the highest, suggesting turmeric extract had the best bioavailability of curcumin. Besides, combined turmeric extract plus bevacizumab treatment significantly inhibited the tumor growth. Such inhibitory effects were stronger than those of curcumin plus bevacizumab or bevacizumab alone and were comparable with those of 5-fluorouracil+leucovorin+oxaliplatin (FOLFOX) plus bevacizumab. Notably, there was no observable side effect induced by turmeric extract treatment while significant side effects were found in FOLFOX-treated mice. In conclusion, combination of turmeric extract with bevacizumab possessed potent anti-tumor effects without observable side effects, strongly suggesting the adjuvant use of turmeric extract in colorectal cancer therapy. Our current findings warrant the confirmation regarding the benefits arising from the combined use of bevacizumab and turmeric in colorectal cancer patients in the near future.

Thymidylate synthase (TS) and excision repair complementing-1 (ERCC-1) were known to be important biomarkers to predict a tumor response to 5-fluorouracil (5-FU) and oxaliplatin, but the relationship between these expressions and tumor response were still unclear. The aim of this study was to determine whether the expression of TS and ERCC-1 protein predict a tumor response in patients with unresectable colorectal cancer treated with mFOLFOX6 therapy as first-line treatment. Fifty patients with unresectable colorectal cancer treated with mFOLFOX6 therapy were enrolled in this study. The expression of TS and ERCC-1 protein in primary cancer cells were examined using immunohistochemistry. There were no significant differences between response rate and the expression of TS or ERCC-1 protein (TS: p>0.99, ERCC-1: p= 0.50). There were no significant differences between progression-free survival time and the expression of TS or ERCC-1 protein (TS: p=0.60, ERCC-1: p=0.60). In this study, the expression TS and ERCC-1 protein may not be useful for the prediction of tumor response in patients with unresectable colorectal cancer treated with mFOLFOX6 therapy.

Background Regorafenib has been demonstrated as effective in refractory metastatic colorectal cancer. Combination use with chemotherapy has not been reported. We examined the efficacy and safety of adding chemotherapy to Regorafenib for the treatment of metastatic colorectal cancer(mCRC) patients. Methods We recruited mCRC patients at our institute who received either regorafenib monotherapy or regorafenib in combination with other chemotherapies. All patients had received chemo and target therapies and presented with disease progression before regorafenib treatment. The primary end point was overall survival. Findings Between September1, 2015 and May 31, 2017, 100 mCRC patients at our institute received regorafenib treatment. 39 patients were excluded due to poor performance, lack of timely treatment, or inadequate clinical data. A total of 34 patients received regorafenib combined with other chemotherapies, and 27 patients received regorafenib alone. Median follow up time was 10.4 and 6.1 months, respectively. The primary end point of median OS was higher in the combination group than in the single use group (20.9m vs 10.3m, p = 0.015). The most frequent adverse events were hand-foot skin reactions(16[47.1%]vs 12[44.4%]), fatigue(6[17.6%] vs 7[25.9%]), gastrointestinal discomfort (7[20.6%] vs 6[22.2%]), neutropenia (4[11.8%] vs 1[3.7%]), diarrhea(4[11.8%] vs 1[3.7%]), and mucositis(5[14.7%] vs 1[3.7%]). Conclusion The present study showed the efficacy and side effects of regorafenib combination treatment. Superiority in median OS and median PFS was noted in the combination group. The sampling difference between the study and observation groups effects justifies the comparison. Further clinical evidence of combination therapy efficacy is pending future studies. PMID:29304109

Efficacy and toxicity of oxaliplatin (Eloxatin; Sanofi-Aventis, Paris, France) combined with irinotecan (IROX) were examined in 383 patients enrolled on the IROX arm of Intergroup Study N9741. This IROX regimen was oxaliplatin 85 mg/m(2) and irinotecan 200 mg/m(2) administered every 3 weeks. The relation between adverse events on IROX to selected characteristics was analyzed. Time to progression (TTP), response rate, and overall survival for patients treated with IROX compared with patients treated with oxaliplatin with 5- fluorouracil (FOLFOX) were updated in this article. Grade >or=3 gastrointestinal and hematologic toxicities were common with 39% patients experiencing neutropenia, 28% diarrhea, and 21% vomiting. Patients ages >70 years experienced higher rates of grade >or=3 toxicity, with significantly higher rates of grade >or=3 hematologic toxicities (P = .02). Long-term toxicity was uncommon, and nearly all cases of grade >or=3 neurotoxicity resolved within 10 months. Fifty-two percent of patients required dose reductions for adverse events, and 26% experienced 119 hospitalizations related to complications of treatment or their disease, with 5 treatment-related deaths. This analysis confirmed prior findings that FOLFOX is superior to IROX in terms of response rate (43% vs 36%, p = 0.002), TTP (9.2 months vs 6.7 months, P < .0001), and overall survival (19.5 months vs 17.3 months, P = .0001). IROX was found to be less active than FOLFOX but with a similar toxicity profile except in patients ages >70 years. Although IROX may be considered in patients intolerant of 5-FU or in patients known to have a dihydropyrimidine dehydrogenase (DPD) deficiency, it should be used with caution in older patients.

Surgery remains the standard of care for patients with colorectal liver metastases (CLMs), with a 5-year survival rate approaching 35%. Perioperative chemotherapy confers a survival benefit in selected patients with CLMs. The use of molecular targeted therapy combined with neoadjuvant chemotherapy for CLMs, however, remains controversial. We reviewed the published data on combination neoadjuvant chemotherapy and molecular targeted therapy for resectable and initially unresectable CLMs. A literature search of the Medline and PubMed databases was conducted to identify studies of neoadjuvant chemotherapy plus molecular targeted therapy in the management of resectable or initially unresectable CLMs. We calculated the pooled proportion and 95% confidence intervals using a random effects model for the relationship of the combination neoadjuvant treatment on the overall response rate and performed a systematic review of all identified studies. The analysis was stratified according to the study design. The data from 11 studies of 908 patients who had undergone systemic chemotherapy plus targeted therapy for CLM were analyzed. The use of combination neoadjuvant therapy was associated with an overall response rate of 68% (95% confidence interval, 63%-73%), with significant heterogeneity observed in the studies (I 2  = 89.35; P < .001). Of the 11 studies, 4 used a combination that included oxaliplatin, 2 included irinotecan, and 5 included a combination of both. Also, 7 studies used cetuximab and 4 bevacizumab. The overall progression-free survival was estimated at 14.4 months. Current evidence suggests that neoadjuvant chemotherapy plus molecular targeted agents for CLM confers high overall response rates. Combination treatment might also increase the resectability rates in initially unresectable CLM. Further studies are needed to examine the survival outcomes, with a focus on the differential role of molecular targeted therapy in the neoadjuvant versus adjuvant setting. Crown Copyright © 2016.

Objective: Previously, we suggested that oxaliplatin (L-OHP)-related grade 3/4 hypersensitivity reactions occurred immediately after the initiation, but grade 1/2 reactions did not. This study was conducted to clarify the risk factors for L-OHP-related hypersensitivity reactions. Methods: Clinical data from 108 Japanese patients with colorectal cancer were analyzed, who were treated with L-OHP-containing regimens, FOLFOX4 and/or mFOLFOX6. The risk factors examined included demographic data, preexisting allergies, laboratory test data, treatment regimen, treatment line of therapy, pretreatment with steroids, total number of cycles and cumulative amount of L-OHP. Results: The incidence of grade 1/2 and grade 3/4 hypersensitivity reactions were found at 13.0% (14/108) and 9.3% (10/108), respectively. Female (P=0.037), preexisting allergies (P=0.004) and lower level of lactate dehydrogenase (P=0.003) were risk factors for grade 1/2 hypersensitivity reactions, and higher neutrophil count (P=0.043) and lower monocyte count (P=0.007) were for grade 3/4 reactions. Total number of cycles were larger in the patients with grade 3/4 reactions than those without reactions (P=0.049). Conclusions: Further extensive examination with a large number of patients is needed to establish a patient management strategy. PMID:21448307

Oesophageal cancer is a highly aggressive disease with about 50% of patients presenting with advanced or metastatic disease at initial diagnosis. In this study we assessed combined microwave ablation (MWA) and systemic chemotherapy in the treatment of liver metastases arising from oesophageal squamous cell carcinoma (OSCC). Between February 2009 and June 2014, OSCC patients who underwent percutaneous MWA + concurrent systemic chemotherapy and systemic chemotherapy alone for liver metastases were enrolled in this study. Overall survival (OS) and progression-free survival (PFS) were recorded and compared between groups. In total 15 patients with 25 liver metastases who underwent ultrasound-guided percutaneous MWA and chemotherapy were enrolled in this study. Technical success was achieved in 96% (24/25) of metastatic liver tumours. No major or minor complications associated with MWA procedures were observed. The median OS and PFS from initial MWA were 13 months and 4 months. The 1-, 2-, 3-, 4-year OS rates after MWA were 53.3%, 26.7%, 13.3%, and 13.3%, respectively. The 1- and 2-year PFS rates after MWA were 26.7% and 13.3%. The OS and PFS of the MWA + systemic chemotherapy group were superior than those of patients who received systemic chemotherapy alone (P = 0.011 and 0.030, respectively). Combined MWA with systemic chemotherapy is a feasible, safe and effective treatment for liver metastases from OSCC.

Introduction According to the Brazilian National Institute of Cancer, gastric cancer is the third leading cause of death among men and the fifth among women in Brazil. Surgical resection is the only potentially curative treatment. The most serious complications associated with surgery are fistulas and dehiscence of the jejunal-esophageal anastomosis. Hiatal hernia refers to herniation of elements of the abdominal cavity through the esophageal hiatus of the diaphragm, though this occurrence is rarely reported as a complication in gastrectomy. Case Report A 76-year-old man was diagnosed with intestinal-type gastric adenocarcinoma. He underwent a total laparoscopic-assisted gastrectomy and D2 lymphadenectomy on May 19, 2015. The pathology revealed a pT4pN3 gastric adenocarcinoma. The patient became clinically stable and was discharged 10 days after surgery. He was subsequently started on adjuvant FOLFOX chemotherapy; however, 9 days after the second cycle, he was brought to the emergency room with nausea and severe epigastric pain. A CT scan revealed a hiatal hernia with signs of strangulation. The patient underwent emergent repair of the hernia and suffered no postoperative complications. He was discharged from the hospital 9 days after surgery. Conclusion Hiatal hernia is not well documented, and its occurrence in the context of gastrectomy is an infrequent complication.

To analyze the outcome and prognosis of autologous hematopoietic stem cell transplantation (AHSCT) combined with high dose radiotherapy/chemotherapy in 22 patients with nasal NK/T cell lymphoma. From July 1992 to December 2005, 22 patients with nasal NK/T cell lymphoma were diagnosed pathologically. Immunophenotyping was performed in 13 cases. The patients were classified by Ann Arbor staging system and international prognosis index (IPI). The patients received cycles of chemotherapy every other two weeks or combined with radiotherapy for remission induction, followed high dose radiotherapy/chemotherapy, combined with autologous peripheral blood stem cell transplantation (APBSCT), or autologous bone-marrow transplantation (ABMT). Patients were given complementary radiotherapy after transplantation if they did not have it before. Twelve patients of IPI 3 -4 received consolidation chemotherapy, and one of them received the second transplantation. The median follow-up duration was 64 (12 - 168) months. The 5 and 8-year overall survivals (OS) were 79.3% and 64.1%, and disease free survivals (DFS) were 36.4% and 27.3%, respectively. The 5-year OS were as follows: for stage I - II and III - IV disease were 90.0% and 70.0% (P = 0. 041); for patients without and with B symptom were 100.0% and 70.7% (P = 0.045); and for IPI 1 - 2 and 3 - 4 were 100.0% and 60.0% (P = 0.035), respectively. Multivariate analysis by COX regression revealed that disease stage, B symptom and IPI were independent prognostic factors. AHSCT combined with high dose radiotherapy/chemotherapy is an effective treatment for patients with poor prognosis nasal NK/T cell lymphoma.

We report the case of a 52-year-old woman with advanced colorectal cancer who was treated with oxaliplatin on a FOLFOX schedule. After 3 cycles of chemotherapy, she started to complain of visual loss, altered color vision and neurological symptoms. Due to the suspicion of ocular and neurological toxicity, antineoplastic treatment was stopped. Her visual field showed a concentric bilateral scotoma and the electrooculogram test revealed severe impairment of the retinal pigment epithelium. Visual acuity, color vision and visual field recovered completely 8 months later, although electrooculogram remained abnormal. Ocular toxicity has been reported as an infrequent adverse event of oxaliplatin. Findings in this case indicate toxicity of this chemotherapeutic agent on the retinal pigment epithelium, which has not been reported before. This damage could be permanent, and it thus differs from previously described oxaliplatin-induced ocular toxicities, which are usually transient and reversible. With increasing use of oxaliplatin as first-line treatment in advanced colorectal cancer, we have to be aware of this possible toxicity. PMID:21151636

The potential role of this parameter in the assessment of response to chemotherapy and bevacizumab was tested in patients with metastatic colorectal cancer with potentially resectable liver metastases (mCRC). (18)F-FDG PET/CT was performed in 18 mCRC patients with liver metastases before treatment and after five cycles of FOLFOX/FOLFIRI and bevacizumab. Of the 18 patients, 16 subsequently underwent resection of liver metastases. Baseline and follow-up SUVmax, and SAM as well as reduction in SUVmax (∆SUVmax) and SAM (∆SAM) of all liver metastases were correlated with morphological response, and progression-free and overall survival (PFS and OS). A significant reduction in metabolic activity of the liver metastases was seen after chemotherapy with a median ∆SUVmax of 25.3% and ∆SAM of 94.5% (p = 0.033 and 0.003). Median baseline SUVmax and SAM values were significantly different between morphological responders and nonresponders (3.8 vs. 7.2, p = 0.021; and 34 vs. 211, p = 0.002, respectively), but neither baseline PET parameters nor morphological response was correlated with PFS or OS. Follow-up SUVmax and SAM as well as ∆SAM were found to be prognostic factors. The median PFS and OS in the patient group with a high follow-up SUVmax were 10.4 months and 32 months, compared to a median PFS of 14.7 months and a median OS which had not been reached in the group with a low follow-up SUVmax (p = 0.01 and 0.003, respectively). The patient group with a high follow-up SAM and a low ∆SAM had a median PFS and OS of 9.4 months and 32 months, whereas the other group had a median PFS of 14.7 months and a median OS which had not been reached (p = 0.002 for both PFS and OS). (18)F-FDG PET imaging is a useful tool to assess treatment response and predict clinical outcome in patients with mCRC who undergo chemotherapy before liver metastasectomy. Follow-up SUVmax, follow-up SAM and ∆SAM were found to be significant prognostic factors for PFS and OS.

Acute hyperammonemic encephalopathy induced by fluoropyrimidines (FPs) is a rare complication. Its pathophysiology remains unclear, especially given the currently used regimens, including intermediate-doses of 5-fluorouracil (5-FU) or oral FP agents. We aimed to characterize the clinical manifestations in cancer patients who developed hyperammonemic encephalopathy after receiving FP-based chemotherapy.We retrospectively reviewed 1786 patients with gastrointestinal or primary-unknown cancer who received FP-based regimens between 2007 and 2012. Eleven patients (0.6%) developed acute hyperammonemic encephalopathy. The incidence according to the administered anticancer drugs were as follows: 5-FU (8 of 1176, 0.7%), S-1 (1 of 679, 0.1%), capecitabine (2 of 225, 0.9%), and tegafur-uracil (UFT) (0 of 39, 0%). Ten patients (90.9%) had at least 1 aggravating factor, including infection, dehydration, constipation, renal dysfunction, and muscle loss. All the 10 patients met the definition of sarcopenia. Median time to the onset of hyperammonemic encephalopathy in the cycle was 3 days (range: 2-21). Three patients (27.3%) developed encephalopathy during the first cycle of the regimen and the remaining 8 patients during the second or more cycles. Seven patients (63.6%) had received at least 1 other FP-containing regimen before without episodes of encephalopathy.All patients recovered soon after immediate discontinuation of chemotherapy and supportive therapies, such as hydration, infusion of branched-chain amino acids, and oral lactulose intake, with a median time to recovery of 2 days (range: <1-7). Four patients (36.4%) received FP-based regimens after improvement of symptoms; 3 patients were successfully managed with dose reduction, and 1 patient, who had developed encephalopathy due to S-1 monotherapy, received modified FOLFOX-6 therapy without encephalopathy later.FP-associated acute hyperammonemic encephalopathy is extremely rare, but a possible event at any time and even during the administration of oral FP agents. Particular attention is warranted when giving FP-based therapy for patients with aggravating factors, such as sarcopenia. This complication can be properly managed with early detection.

Purpose: To assess the efficacy of balloon dilation combined with chemotherapy and/or radiation therapy for palliation of dysphagia due to malignant esophagogastric junction strictures. Methods: Fluoroscopically guided balloon dilation was attempted in 20 patients. The causes of strictures were gastric adenocarcinoma (n = 10) and esophageal squamous cell carcinoma (n = 10). Scheduled chemotherapy and/or radiation therapy followed balloon dilation in all patients. Results: There were no technical failures or major complications. After balloon dilation, 15 (75%) patients showed improvement of dysphagia. No patient complained of reflux esophagitis during the follow-up period. Among the 15 patients, seven needed no furthermore » treatment for palliation of dysphagia until their deaths. The remaining eight patients underwent repeat balloon dilation(n = 4) or stent placement (n = 4)3-43 weeks (mean 15 weeks) after the initial balloon dilation because of recurrent dysphagia. Conclusion: Balloon dilation combined with chemotherapy and/or radiation therapy seems to be an easy and reasonably effective palliative treatment for malignant esophagogastric strictures.« less

Bevacizumab, a humanized monoclonal antibody targeting vascular endothelial growthfactor (VEGF), has been approvedfor concurrent treatment with first line chemotherapy in advanced epithelial ovarian cancer. A case of an advanced stage epithelial ovarian cancer (EOC) receiving a combination of bevacizumab, carboplatin andpaclitaxel chemotherapy was reported. A 44-year-old woman was presented with abdominal discomfort and distention for 4 months. Bilateral 12 cm diameter ovarian tumors were diagnosed as FIGO stage IIIc after surgical staging operation. Histopathology report showed the mixed type of serous and endometriod adenocarcinoma. The patient was then started on carboplatin/paclitaxel combination chemotherapy for 6 cycles after surgery every 3 weeks. Bevacizumab (7.5 mg/ m2) was concurrently administered with chemotherapy every 3 weeks startingfrom the 2nd cycle. A complete remission was achieved after the end of the chemotherapy treatment. Bevacizumab was continued for one year after the completion of the standard chemotherapy. Bone marrow suppression, hypertension and proteinuria were not found during Bevacizumab treatment. At bevacizumab treatment completion, a platinum-sensitive recurrent ovarian cancer was diagnosed at the two weeks postprogram routine check-up. The patient was counseled to start second line chemotherapy treatment and has yet to come back with her decision. Combination of bevacizumab, carboplatin and paclitaxelfor first line chemotherapy in advanced EOC in this case had no serious side effects and need further study.

This study was conducted to compare the efficacy of a combination of icotinib and chemotherapy with icotinib or chemotherapy alone in untreated non-small cell lung cancer (NSCLC) patients harboring epidermal growth factor receptor (EGFR)-sensitive mutations and to analyze the curative effect of different treatments on different genetic mutations (EGFR 19 exon deletion and L858R mutation) in a real-life setting. One hundred ninety-one patients were studied in this retrospective analysis from January 2013 to December 2015. The baseline characteristics, curative effects and adverse events of patients were analyzed. The primary endpoint was progression free survival (PFS). Longer PFS and overall survival (OS), and better objective response rate (ORR) were observed in the combination group compared to icotinib or chemotherapy along. For patients with an EGFR 19 exon deletion, the PFS, OS, and ORR in the combination group were superior to those in the icotinib or chemotherapy group. For the patients with the EGFR L858R mutation, better PFS and ORR were observed in the combination group, but OS was not obviously prolonged. Grade 3 or 4 adverse events were most commonly reported with combination therapy or chemotherapy alone. No possible drug-related interstitial lung disease or of drug related deaths occurred. The combination of icotinib and chemotherapy in patients with untreated NSCLC harboring sensitive EGFR mutations resulted in improved PFS and OS, especially in those who harbored the EGFR exon 19 deletion.

Purpose Patients with squamous non-small-cell lung cancer (NSCLC) have poor prognosis and limited treatment options. This randomized, double-blind, phase III study investigated the efficacy and safety of first-line ipilimumab or placebo plus paclitaxel and carboplatin in advanced squamous NSCLC. Patients and Methods Patients with stage IV or recurrent chemotherapy-naïve squamous NSCLC were randomly assigned (1:1) to receive paclitaxel and carboplatin plus blinded ipilimumab 10 mg/kg or placebo every 3 weeks on a phased induction schedule comprising six chemotherapy cycles, with ipilimumab or placebo from cycles 3 to 6 and then, after induction treatment, ipilimumab or placebo maintenance every 12 weeks for patients with stable disease or better. The primary end point was overall survival (OS) in patients receiving at least one dose of blinded study therapy. Results Of 956 randomly assigned patients, 749 received at least one dose of blinded study therapy (chemotherapy plus ipilimumab, n = 388; chemotherapy plus placebo, n = 361). Median OS was 13.4 months for chemotherapy plus ipilimumab and 12.4 months for chemotherapy plus placebo (hazard ratio, 0.91; 95% CI, 0.77 to 1.07; P = .25). Median progression-free survival was 5.6 months for both groups (hazard ratio, 0.87; 95% CI, 0.75 to 1.01). Rates of grade 3 or 4 treatment-related adverse events (TRAEs), any-grade serious TRAEs, and TRAEs leading to discontinuation were numerically higher with chemotherapy plus ipilimumab (51%, 33%, and 28%, respectively) than with chemotherapy plus placebo (35%, 10%, and 7%, respectively). Seven treatment-related deaths occurred with chemotherapy plus ipilimumab, and one occurred with chemotherapy plus placebo. Conclusion The addition of ipilimumab to first-line chemotherapy did not prolong OS compared with chemotherapy alone in patients with advanced squamous NSCLC. The safety profile of chemotherapy plus ipilimumab was consistent with that observed in previous lung and melanoma studies. Ongoing studies are evaluating ipilimumab in combination with nivolumab in this population.

Background First-line therapy for advanced non-small-cell lung cancer (NSCLC) that lacks targetable mutations is platinum-based chemotherapy. Among patients with a tumor proportion score for programmed death ligand 1 (PD-L1) of 50% or greater, pembrolizumab has replaced cytotoxic chemotherapy as the first-line treatment of choice. The addition of pembrolizumab to chemotherapy resulted in significantly higher rates of response and longer progression-free survival than chemotherapy alone in a phase 2 trial. Methods In this double-blind, phase 3 trial, we randomly assigned (in a 2:1 ratio) 616 patients with metastatic nonsquamous NSCLC without sensitizing EGFR or ALK mutations who had received no previous treatment for metastatic disease to receive pemetrexed and a platinum-based drug plus either 200 mg of pembrolizumab or placebo every 3 weeks for 4 cycles, followed by pembrolizumab or placebo for up to a total of 35 cycles plus pemetrexed maintenance therapy. Crossover to pembrolizumab monotherapy was permitted among the patients in the placebo-combination group who had verified disease progression. The primary end points were overall survival and progression-free survival, as assessed by blinded, independent central radiologic review. Results After a median follow-up of 10.5 months, the estimated rate of overall survival at 12 months was 69.2% (95% confidence interval [CI], 64.1 to 73.8) in the pembrolizumab-combination group versus 49.4% (95% CI, 42.1 to 56.2) in the placebo-combination group (hazard ratio for death, 0.49; 95% CI, 0.38 to 0.64; P<0.001). Improvement in overall survival was seen across all PD-L1 categories that were evaluated. Median progression-free survival was 8.8 months (95% CI, 7.6 to 9.2) in the pembrolizumab-combination group and 4.9 months (95% CI, 4.7 to 5.5) in the placebo-combination group (hazard ratio for disease progression or death, 0.52; 95% CI, 0.43 to 0.64; P<0.001). Adverse events of grade 3 or higher occurred in 67.2% of the patients in the pembrolizumab-combination group and in 65.8% of those in the placebo-combination group. Conclusions In patients with previously untreated metastatic nonsquamous NSCLC without EGFR or ALK mutations, the addition of pembrolizumab to standard chemotherapy of pemetrexed and a platinum-based drug resulted in significantly longer overall survival and progression-free survival than chemotherapy alone.

The purpose of this study was to evaluate the effectiveness and adverse events of combination chemotherapy with oral S-1 administration following docetaxel (DOC) treatment by superselective intra-arterial infusion as neo-adjuvant chemotherapy (NAC) for patients with oral squamous cell carcinoma. Thirteen patients were enrolled in this study (9 men and 4 women, with a mean age of 61. 0 years). All patients were given S-1 65mg/m(2) per day for 14 days, and DOC 40-50mg/m(2) by intraarterial infusion was administered. The locoregional response evaluated 3 weeks after administration was 100%, including a 69. 2% complete response. According to Oboshi and Shimosato's classification, histological evaluation of surgical specimens revealed that 3 cases were Grade II a, 4 cases Grade II b, 1 case Grade IV a, and 4 cases Grade IV c. The severe side effects were neutropenia and cerebral infarction. The present study suggests that combination chemotherapy with S-1 and DOC by superselective intra-arterial infusion would be an effective and safe regimen in NAC for oral squamous cell carcinomas.

We evaluate the feasibility and efficacy of combination chemotherapy including single intraperitoneal( IP)administration of paclitaxel(PTX), followed by triplet chemotherapy(PTX, cisplatin[CDDP]and S-1: PCS)for CY1P0 gastric cancer. First of all, we performed staging laparoscopy and confirmed CY1P0, and secondary, administrated PTX intraperitoneally. Thirdly, patients received PCS chemotherapy for 2 courses. After antitumor effect had been confirmed, we performed second look laparoscopy. In the case of CY0P0, we performed gastrectomy with D2 lymph nodes dissection. Total 4 patients were enrolled. Grade 3 leukopenia and neutropenia were observed in one patient while intraperitoneal and systemic-chemotherapy. One patients showed PR and 3 patients showed SD. All patients underwent second look laparoscopy. CY0P0 was observed in all patients and gastrectomy with D2 dissection was performed for all patients. Postoperative complications were observed in 2 patients. Two patients were still alive without recurrence, while the remaining 2 had died of liver metastasis and #16 LN metastasis. Combination chemotherapy including single IP PTX followed by PCS systemic-chemotherapy for CY1P0 gastric cancer is feasible and efficient.

Between March, 1976, and December, 1982, 70 of 157 patients (45%) undergoing single-stage radical cystectomy with pelvic lymphadenectomy and urinary diversion with the intent to cure invasive bladder cancer were found to have pathologic Stage P3B, P4 and/or N + disease. Thirty-four of the 70 patients received adjuvant prophylactic chemotherapy after cystectomy and 36 patients were followed expectantly. From 1976 through 1977 adjuvant chemotherapy consisted of cyclophosphamide 1 Gm/M2 each month for six months; from 1978 through June, 1980, adjuvant chemotherapy consisted of cis-platinum 100 mg/M2 each month for four months with the exception of 1 patient treated more aggressively with combination chemotherapy (CISCA). Since July, 1980, a prospective study has been utilized in which patients were randomized into two groups, Group A receiving combination chemotherapy and Group B followed up expectantly; adjuvant chemotherapy appears to result in a slight delay in time to relapse but no influence in overall survival was observed.

To explore the effectiveness and safety of combined chemotherapy with pegasparaginase (PEG-Asp) for treatment of patients with acute lymphoblastic leukemia (ALL) and T cell non-Hodgkin's lymphoma (T-NHL) patients. A total of 62 ALL or T-NHL patients were diagnosed and treated in our department and were enrolled in this study. Among them, 22 patients received the combined chemotherapy with PEG-Asp, while the other 40 patients received the standard chemotherapy with L-asparaginase (L-Asp) as the control. Therapeutic effectiveness, adverse effects, duration and expense of hospitalization, treatment-related mortality and survival were evaluated and compared in 2 different groups. In group of combined chemotherapy with PEG-Asp, the overall response rate was 90.91% (20 cases), among them CR rate and PR rate are 77.27% (17 cases) and 13.64% (3 cases), respectively. In the group of standard chemotherapy with L-Asp, the overall response rate was 87.5% (35 cases), among them CR rate and PR rate were 72.5% (29 cases) and 15% (6 cases), respectively. The difference neither between PEG-Asp and L-Asp chemotherapy groups nor between ALL and T-NHL subgroups was significant (P > 0.05). The 6-month and 12-month overall survival rates were not significantly different between the PEG-Asp and L-Asp chemotherapy groups, respectively (P > 0.05). The adverse effects were identified as degree 1-2 according to the WHO criteria of drug toxicity. Neither the adverse effects identified as degree 3-4 nor the treatment-related death were observed. Expect for allergy and hyperglycaemia, the difference of side-effect incidence between the two groups were not significant (P > 0.05). The treatment for all the patients in PEG-Asp chemotherapy group was completed, while the treatment with L-Asp was completed only in 29 cases. Moreover, both average duration and expense of hospitalization after the combined chemotherapy were less than the control. With higher response rate, lower drug toxicity and allergy incidence, the combined chemotherapy with PEG-Asp can replace the standard chemotherapy with L-Asp in the treatment of ALL and T-NHL. The optimization of the combined chemotheropeutic protocols for more cases and long-term survival rates need to further and deeply explorate.

The decision whether to treat older adults with advanced cancer with standard therapy (ST) or reduced therapy (RT) is complicated by heterogeneity in aging. We assessed the potential utility of the chemotherapy toxicity risk score (CTRS) [J Clin Oncol 2011;29:3457-3465] for treatment decisions in older adults. This was a prospective observational study of patients aged ≥65 years receiving first-line chemotherapy for advanced cancer for which combination chemotherapy is the standard of care. Patients were categorized as high risk (CTRS ≥10), for whom RT (dose-reduced combination or single-agent chemotherapy) is deemed appropriate, or nonhigh risk (CTRS <10), for whom ST is deemed appropriate for toxicity. The primary objective was to estimate the agreement in chemotherapy choice (ST vs. RT) between the treating physician and the CTRS using a κ statistic. Fifty-eight patients (median age, 71 years) were enrolled. Thirty-eight patients received ST (21 had CTRS <10, and 17 had CTRS ≥10), and 20 patients received RT (12 had CTRS ≥10, and 8 had CTRS <10), with minimal agreement in chemotherapy choice (κ = 0.14; 95% CI, -0.10 to 0.38). Grade 3-4 toxicity and hospitalization occurred in 60% and 27% of 55 patients with follow-up data, respectively. Among patients receiving ST, patients with CTRS ≥10 had a higher incidence of toxicity (88% vs. 40%, p  = .006) and hospitalization (50% vs. 15%, p  = .03) than those with CTRS <10. Older patients with cancer with a high CTRS who receive combination chemotherapy have an exceedingly high rate of severe toxicity and hospitalization. The potential utility of the chemotherapy toxicity risk score (CTRS) in old adults with advanced solid tumors receiving first-line chemotherapy was assessed. Little agreement was found between chemotherapy treatment decisions based on the clinical impression versus what was recommended based on the CTRS. Among patients treated with standard-dose combination chemotherapy, patients with CTRS ≥10 had a very high incidence of grade 3-4 toxicities and hospitalization, which was significantly greater than that of patients with a low CTRS (<10). These findings suggest that the addition of CTRS to the clinical impression has a potential to improve treatment decisions. © AlphaMed Press 2018.

To assess the safety of Liena polypeptide injection (produced by JILIN FSENS PHARMACEUTICAL CO.,LTD) combined with chemotherapy in treating patients with advanced cancers. A consecutive cohort of patients with advanced cancers were treated with Liena polypeptide injection combined with chemotherapy. And chemotherapy for patients with advanced cancers were adopted from regimens suggested by NCCN guideline. Liena polypeptide injection was intravenously injected at a dosage of 2 ml plus 100ml normal saline for continuous 7 days during chemotherapy as one course. After at least two courses of treatment, safety and side effects were evaluated. There were 20 female and 14 male patients with advanced cancer recruited into this study, including 10 patients with breast, 8 patients with colorectal, 8 patients with lung, 4 patients with gastric, and 1 patient with esophageal cancer, as well as 1 patient with non-Hodgkin's lymphoma, 1 patient with low pharyngeal and 1 patient with urethral cancer. The median age of patients was 59 (40-82) years. Incidences of Grade 1 to 2 myelosuppression was observed in 5/34 patients, and Grade 1 to 2 elevation of hepatic enzyme was recorded in 3/34 patients. Adverse effects on the gastrointestinal tract were documented in 5/34 patients, and were Grade 1. No Grade 3-4 toxicities were diagnosed. No treatment related death was found. Liena polypeptide injection combined with chemotherapy was safe in treating several sites of tumors, that mainly included lung, colorectal and breast cancer. However, further study should be conducted to clarify the effectiveness of this treatment.

The role of elective nodal irradiation (ENI) in radiotherapy for esthesioneuroblastoma (ENB) has not been clearly defined. We analyzed treatment outcomes of patients with ENB and the frequency of cervical nodal failure in the absence of ENI. Between August 1996 and December 2007, we consulted with 19 patients with ENB regarding radiotherapy. Initial treatment consisted of surgery alone in 2 patients; surgery and postoperative radiotherapy in 4; surgery and adjuvant chemotherapy in 1; surgery, postoperative radiotherapy, and chemotherapy in 3; and chemotherapy followed by radiotherapy or concurrent chemoradiotherapy in 5. Five patients did not receive planned radiotherapy because of disease progression. Including 2 patients who received salvage radiotherapy, 14 patients were treated with radiotherapy. Elective nodal irradiation was performed in 4 patients with high-risk factors, including 3 with cervical lymph node metastasis at presentation. Fourteen patients were analyzable, with a median follow-up of 27 months (range, 7-64 months). The overall 3-year survival rate was 73.4%. Local failure occurred in 3 patients (21.4%), regional cervical failure in 3 (21.4%), and distant failure in 2 (14.3%). No cervical nodal failure occurred in patients treated with combined systemic chemotherapy regardless of ENI. Three cervical failures occurred in the 4 patients treated with ENI or neck dissection (75%), none of whom received systemic chemotherapy. ENI during radiotherapy for ENB seems to play a limited role in preventing cervical nodal failure. Omitting ENI may be an option if patients are treated with a combination of radiotherapy and chemotherapy. Copyright © 2011 Elsevier Inc. All rights reserved.

Osteosarcoma is the most common primary bone tumor in children and young adults. The median survival of osteosarcoma patients has not significantly improved since 1990, despite administration of different classes of chemotherapy agents, such as methotrexate, cisplatin and doxorubicin. Cancer stem cells (CSCs) are responsible for the resistance of osteosarcoma to chemotherapy and OCT4, SOX2 and SSEA4 have been used to identify CSCs in osteosarcoma. Here, we used low-passage patient-derived osteosarcoma cells and osteosarcoma cells directly isolated from patients before and after chemotherapy treatments to evaluate the effects of chemotherapy on stem cell markers expression. We demonstrate that primary osteosarcoma cells are resistant to methotrexate treatment and sensitive to cisplatin and doxorubicin in vitro. We also verified that cisplatin and doxorubicin reduce the expression of SOX2 and OCT4 in primary osteosarcoma cells whereas methotrexate does not alter SOX2 and OCT4 expression, however it increases SSEA4 expression in primary osteosarcoma cells. Finally, we found that, although the combination treatment cisplatin plus doxorubicin inhibited the in vivo growth of osteosarcoma cells in NOD-SCID gamma mice subcutaneously injected with SaOs2, the combination treatment cisplatin plus doxorubicin plus methotrexate did not inhibit the in vivo growth of these cells. These observations may provide an explanation for the poor response of osteosarcomas to chemotherapy and point to the need of reevaluating the therapeutic strategies for human osteosarcomas.

Osteosarcoma is the most common primary bone tumor in children and young adults. The median survival of osteosarcoma patients has not significantly improved since 1990, despite administration of different classes of chemotherapy agents, such as methotrexate, cisplatin and doxorubicin. Cancer stem cells (CSCs) are responsible for the resistance of osteosarcoma to chemotherapy and OCT4, SOX2 and SSEA4 have been used to identify CSCs in osteosarcoma. Here, we used low-passage patient-derived osteosarcoma cells and osteosarcoma cells directly isolated from patients before and after chemotherapy treatments to evaluate the effects of chemotherapy on stem cell markers expression. We demonstrate that primary osteosarcoma cells are resistant to methotrexate treatment and sensitive to cisplatin and doxorubicin in vitro. We also verified that cisplatin and doxorubicin reduce the expression of SOX2 and OCT4 in primary osteosarcoma cells whereas methotrexate does not alter SOX2 and OCT4 expression, however it increases SSEA4 expression in primary osteosarcoma cells. Finally, we found that, although the combination treatment cisplatin plus doxorubicin inhibited the in vivo growth of osteosarcoma cells in NOD-SCID gamma mice subcutaneously injected with SaOs2, the combination treatment cisplatin plus doxorubicin plus methotrexate did not inhibit the in vivo growth of these cells. These observations may provide an explanation for the poor response of osteosarcomas to chemotherapy and point to the need of reevaluating the therapeutic strategies for human osteosarcomas.

The efficacy and safety of a combination of chemotherapeutic agent compared with single-agent chemotherapy in the second-line setting of advanced urothelial carcinoma (UC) are unclear. We aimed to study the survival impact of single-agent compared with doublet chemotherapy as second-line chemotherapy of advanced UC. Literature was searched for studies including single-agent or doublet chemotherapy in the second-line setting after platinum-based chemotherapy. Random-effects models were used to pool trial-level data according to treatment arm, including median progression-free survival (PFS), overall survival (OS), objective response rate (ORR) probability, and grade 3-4 toxicity. Univariable and multivariable analyses, including sensitivity analyses, were carried out, adjusting for the percent of patients with ECOG performance status ≥1 and hepatic metastases. Forty-six arms of trials including 1910 patients were selected: 22 arms with single agent (n = 1202) and 24 arms with doublets (n = 708). The pooled ORR with single agents was 14.2% [95% confidence interval (CI) 11.1-17.9] versus 31.9% [95% CI 27.3-36.9] with doublet chemotherapy. Pooled median PFS was 2.69 and 4.05 months, respectively. The pooled median OS was 6.98 and 8.50 months, respectively. Multivariably, the odds ratio for ORR and the pooled median difference of PFS were statistically significant (P < 0.001 and P = 0.002) whereas the median difference in OS was not (P = 0.284). When including single-agent vinflunine or taxanes only, differences were significant only for ORR (P < 0.001) favoring doublet chemotherapy. No statistically significant differences in grade 3-4 toxicity were seen between the two groups. Despite significant improvements in ORR and PFS, doublet regimens did not extend OS compared with single agents for the second-line chemotherapy of UC. Prospective trials are necessary to elucidate the role of combination chemotherapy, with or without targeted agents, in the salvage setting. Currently, improvements in this field should be pursued considering single-agent chemotherapy as the foundation for new more active combinations. © The Author 2015.

Extraskeletal Ewings sarcoma are rare tumors for which there is no consensus on optimal management. A retrospective review of the clinical features, treatment and outcome of patients with extraskeletal Ewings sarcoma who reported to a single institution between January 1992-December 2003 is reported. A total of 19 patients with extraskeletal Ewings sarcoma were identified. Of these, 4 patients had metastatic disease at presentation and 15 patients with non-metastatic disease received combined modality treatment with primary combination chemotherapy followed by local treatment with radiotherapy or surgery. Disease free survival and overall survival for patients with non metastatic disease after combined modality treatment were 60% and 30% respectively. The significant predictors for prolonged disease free survival and overall survival were high haemoglobin (p = 0.002), low lactate dehydrogenase (p = 0.028), chemotherapy with Vincristine, Adriamycin, Cyclophosphamide, Ifosfamide and Etoposide regime (p = 0.008) and complete response to chemotherapy (p = 0.001). Aggressive combination chemotherapy followed by complete surgery or radiotherapy to a dose of more than 50 Gy is essential to confer optimal outcome for patients with extraskeletal Ewings sarcoma.

Receipt of 6 cycles of adjuvant chemotherapy (AC) is standard of care in pancreatic cancer (PC). Neoadjuvant chemotherapy (NAC) is increasingly utilized; however, optimal number of cycles needed alone or in combination with AC remains unknown. We sought to determine the optimal number and sequence of perioperative chemotherapy cycles in PC. Single institutional review of all resected PCs from 2008 to 2015. The impact of cumulative number of chemotherapy cycles received (0, 1-5, and ≥6 cycles) and their sequence (NAC, AC, or NAC + AC) on overall survival was evaluated Cox-proportional hazard modeling, using 6 cycles of AC as reference. A total of 522 patients were analyzed. Based on sample size distribution, four combinations were evaluated: 0 cycles = 12.1%, 1-5 cycles of combined NAC + AC = 29%, 6 cycles of AC = 25%, and ≥6 cycles of combined NAC + AC = 34%, with corresponding survival. 13.1, 18.5, 37, and 36.8 months. On MVA (P < 0.0001), tumor stage [hazard ratio (HR) 1.35], LNR (HR 4.3), and R1 margins (HR 1.77) were associated with increased hazard of death. Compared with 6 cycles AC, receipt of 0 cycles [HR 3.57, confidence interval (CI) 2.47-5.18] or 1-5 cycles in any combination (HR 2.37, CI 1.73-3.23) was associated with increased hazard of death, whereas receipt of ≥6 cycles in any sequence was associated with optimal and comparable survival (HR 1.07, CI 0.78-1.47). Receipt of 6 or more perioperative cycles of chemotherapy either as combined neoadjuvant and adjuvant or adjuvant alone may be associated with optimal and comparable survival in resected PC.

The application of newer signaling pathway-targeted agents has become an important addition to chemotherapy in the treatment of advanced non-small cell lung cancer (NSCLC). In this study, we evaluated the efficacy and toxicities of PKC inhibitors combined with chemotherapy versus chemotherapy alone for patients with advanced NSCLC systematically. Literature retrieval, trials selection and assessment, data collection, and statistic analysis were performed according to the Cochrane Handbook 5.1.0. The outcome measures were tumor response rate, disease control rate, progression-free survival (PFS), overall survival (OS), and adverse effects. Five randomized controlled trials, comprising totally 1,005 patients, were included in this study. Meta-analysis showed significantly decreased response rate (RR 0.79; 95 % CI 0.64-0.99) and disease control rate (RR 0.90; 95 % CI 0.82-0.99) in PKC inhibitors-chemotherapy groups versus chemotherapy groups. There was no significant difference between the two treatment groups regarding progression-free survival (PFS, HR 1.05; 95 % CI 0.91-1.22) and overall survival (OS, HR 1.00; 95 % CI 0.86-1.16). The risk of grade 3/4 neutropenia, leucopenia, and thrombosis/embolism increased significantly in PKC inhibitors combination groups as compared with chemotherapy alone groups. The use of PKC inhibitors in addition to chemotherapy was not a valid alternative for patients with advanced NSCLC.

Purpose: To compare the efficacy of intra-arterial chemotherapy combined with intravesical chemotherapy versus intravesical chemotherapy alone for T1G3 bladder transitional cell carcinoma (BTCC) followed by bladder-preserving surgery. Materials and Methods: Sixty patients with T1G3 BTCC were randomly divided into two groups. After bladder-preserving surgery, 29 patients (age 30-80 years, 24 male and 5 female) received intra-arterial chemotherapy in combination with intravesical chemotherapy (group A), whereas 31 patients (age 29-83 years, 26 male and 5 female) were treated with intravesical chemotherapy alone (group B). Twenty-nine patients were treated with intra-arterial epirubicin (50 mg/m{sup 2}) + cisplatin (60 mg/m{sup 2}) chemotherapy 2-3more » weeks after bladder-preserving surgery once every 4-6 weeks. All of the patients received the same intravesical chemotherapy: An immediate prophylactic was administered in the first 6 h. After that, therapy was administered one time per week for 8 weeks and then one time per month for 8 months. The instillation drug was epirubicin (50 mg/m{sup 2}) and lasted for 30-40 min each time. The end points were tumour recurrence (stage Ta, T1), tumour progression (to T2 or greater), and disease-specific survival. During median follow-up of 22 months, the overall survival rate, tumour-specific death rate, recurrence rate, progression rate, time to first recurrence, and adverse reactions were compared between groups. Results: The recurrence rates were 10.3 % (3 of 29) in group A and 45.2 % (14 of 31) in group B, and the progression rates were 0 % (0 of 29) in group A and 22.6 % (7 of 31) in group B. There was a significant difference between the two groups regarding recurrence (p = 0.004) and progression rates (p = 0.011). Median times to first recurrence in the two groups were 15 and 6.5 months, respectively. The overall survival rates were 96.6 and 87.1 %, and the tumour-specific death rates were 0 % (0 of 29) and 13.5 % (4 of 31) in groups A and B, respectively. During the intra-arterial chemotherapy cycle, although more than 50 % patients experienced some toxicities, most were minor and reversible [grade 1-2 (46.7 %) vs. grade 1-2 (6.9 %)]. Conclusion: These findings suggest that combining intra-arterial chemotherapy with intravesical chemotherapy could delay tumour recurrence and progression compared with intravesical chemotherapy alone and this type treatment is relatively safe.« less

Liver resection for colorectal cancer metastases

Questions Should surgery be considered for colorectal cancer (crc) patients who have liver metastases plus (a) pulmonary metastases, (b) portal nodal disease, or (c) other extrahepatic metastases (ehms)? What is the role of chemotherapy in the surgical management of crc with liver metastases in (a) patients with resectable disease in the liver, or (b) patients with initially unresectable disease in the liver that is downsized with chemotherapy (“conversion”)? What is the role of liver resection when one or more crc liver metastases have radiographic complete response (rcr) after chemotherapy? Perspectives Advances in chemotherapy have improved survival in crc patients with liver metastases. The 5-year survival with chemotherapy alone is typically less than 1%, although two recent studies with folfox or folfoxiri (or both) reported rates of 5%–10%. However, liver resection is the treatment that is most effective in achieving long-term survival and offering the possibility of a cure in stage iv crc patients with liver metastases. This guideline deals with the role of chemotherapy with surgery, and the role of surgery when there are liver metastases plus ehms. Because only a proportion of patients with crc metastatic disease are considered for liver resection, and because management of this patient population is complex, multidisciplinary management is required. Methodology Recommendations in the present guideline were formulated based on a prepublication version of a recent systematic review on this topic. The draft methodology experts, and external review by clinical practitioners. Feedback was incorporated into the final version of the guideline. Practice Guideline These recommendations apply to patients with liver metastases from crc who have had or will have a complete (R0) resection of the primary cancer and who are being considered for resection of the liver, or liver plus specific and limited ehms, with curative intent. 1(a). Patients with liver and lung metastases should be seen in consultation with a thoracic surgeon. Combined or staged metastasectomy is recommended when, taking into account anatomic and physiologic considerations, the assessment is that all pulmonary metastases can also be completely removed. Furthermore, liver resection may be indicated in patients who have had a prior lung resection, and vice versa. 1(b). Routine liver resection is not recommended in patients with portal nodal disease. This group includes patients with radiologically suspicious portal nodes or malignant portal nodes found preoperatively or intraoperatively. Liver plus nodal resection, together with perioperative systemic therapy, may be an option—after a full discussion with the patient—in cases with limited nodal involvement and with metastases that can be completely resected. 1(c). Routine liver resection is not recommended in patients with nonpulmonary ehms. Liver plus extrahepatic resection, together with perioperative systemic therapy, may be an option—after a full discussion with the patient—for metastases that can be completely resected. 2(a). Perioperative chemotherapy, either before and after resection, or after resection, is recommended in patients with resectable liver metastatic disease. This recommendation extends to patients with ehms that can be completely resected (R0). Risks and potential benefits of perioperative chemotherapy should be discussed for patients with resectable liver metastases. The data on whether patients with previous oxaliplatin-based chemotherapy or a short interval from completion of adjuvant therapy for primary crc might benefit from perioperative chemotherapy are limited. 2(b). Liver resection is recommended in patients with initially unresectable metastatic liver disease who have a sufficient downstaging response to conversion chemotherapy. If complete resection has been achieved, postoperative chemotherapy should be considered. 3. Surgical resection of all lesions, including lesions with rcr, is recommended when technically feasible and when adequate functional liver can be left as a remnant. When a lesion with rcr is present in a portion of the liver that cannot be resected, surgery may still be a reasonable therapeutic strategy if all other visible disease can be resected. Postoperative chemotherapy might be considered in those patients. Close follow-up of the lesion with rcr is warranted to allow localized treatment or further resection for an in situ recurrence.

In the past decade of clinical studies, the combination of chemotherapy with cytokine induced killer (CIK) cell transfusion has confirmed a promised efficacy in several types of cancer. CIK cells are a mixture of T lymphocytes, generated from peripheral blood mononuclear cells induced by multiple cytokines. This study was aimed to evaluate the clinical efficacy of chemotherapy combined with CIK- cell therapy in patients with extensive stage small cell lung cancer (ES SCLC). Forty four patients with ES SCLC were enrolled in this study. All the patients received treatment from Oct 2010 to Sep 2013 in the First Affiliated Hospital of Zhengzhou University. Included patients were equally divided into 2 groups according to the treatment strategies. Patients in the combined treatment group received chemotherapy combined with CIK-cell transfusion and patients in the control group received chemotherapy alone. The short-term effects, overall survival (OS), progress free survival (PFS) and therapy-related adverse events were analyzed retrospectively. Short-term efficacy evaluation indicated that the total response rates in the combined treatment group and control group were 40.9% (9/22) and 9.1% (2/22), respectively. There was a significant difference between the two groups (p=0.0339). Furthermore, the PFS of the combined treatment group was significantly longer than that of the control group (8 vs. 4months, P=0.005). No severe side effect was observed after transfusion of CIK cells. These results indicated that chemotherapy combined with CIK-cell immunotherapy might provide a safe and effective treatment for patients with ES SCLC. Copyright © 2016. Published by Elsevier B.V.

Conventional cytotoxic chemotherapy is highly effective in certain cancers but causes dose-limiting damage to normal proliferating cells, especially hematopoietic stem and progenitor cells (HSPCs). Serial exposure to cytotoxics causes a long-term hematopoietic compromise ("exhaustion"), which limits the use of chemotherapy and success of cancer therapy. We show that the coadministration of G1T28 (trilaciclib), which is a small-molecule inhibitor of cyclin-dependent kinases 4 and 6 (CDK4/6), contemporaneously with cytotoxic chemotherapy protects murine hematopoietic stem cells (HSCs) from chemotherapy-induced exhaustion in a serial 5-fluorouracil treatment model. Consistent with a cell-intrinsic effect, we show directly preserved HSC function resulting in a more rapid recovery of peripheral blood counts, enhanced serial transplantation capacity, and reduced myeloid skewing. When administered to healthy human volunteers, G1T28 demonstrated excellent in vivo pharmacology and transiently inhibited bone marrow (BM) HSPC proliferation. These findings suggest that the combination of CDK4/6 inhibitors with cytotoxic chemotherapy should provide a means to attenuate therapy-induced BM exhaustion in patients with cancer.

In the context of gastric cancer, lymph node target volume delineation for post-operative radiotherapy is currently built on the traditional system of dividing the stomach and 2-D treatment methods. Here, we have proposed a new delineation approach with irradiation indications for lymph node stations. Its safety and efficacy were evaluated in a phase II clinical trial. Fifty-four gastric cancer patients with D2 lymph node dissection received 2 cycles of FOLFOX4. They subsequently received concurrent chemoradiotherapy (45 Gy at 1.8 Gy per fraction, 5 fractions per week for 5 weeks) with a 5-fluorouracil/leucovorin regimen, followed by 4 additional FOLFOX4 cycles. The target volume included the remnant stomach, anastomosis site, tumor bed, and regional lymph nodes selected through our new approach by taking gastric arteries as references. The most common grade 3-4 adverse event was neutropenia (14.8%). Neutropenia, anemia, and nausea were common grade 1-2 toxicities. No treatment-related deaths occurred during treatment. The 3-year overall, disease-free, and locoregional recurrence-free survival rates were 81.6%, 70.2%, and 91.1%, respectively. Eight patients developed peritoneal or distant metastases. Using our new approach and irradiation indications, delineation of the target volume of post-operative lymph node stations was feasible and well tolerated after D2 resection in patients with gastric cancer.

Leucovorin is a reduced form of folic acid, which has multiple uses.(1) In this case report, it is used in combination with fluorouracil in the treatment of colon cancer. We describe a 53-year-old male, who was started on FOLFOX 6 + bevacizumab who experienced a hypersensitivity reaction to leucovorin. There have been very few cases of leucovorin hypersensitivity reactions reported in the literature. In this case, symptoms include flushing, hives, body pain, headaches, elevated blood pressures, and general discomfort. Although leucovorin reactions are considered rare, one should be aware of the types of reactions that can occur with leucovorin.

Lung and prostate cancers are major health problems worldwide. Treatments with standard chemotherapy agents are relatively ineffective. Combination chemotherapy gives better treatment than a single agent because the drugs can inhibit the cancer in different pathways, but new therapeutic agents are needed for the treatment of both tumor types. Bradykinin (BK) antagonists offer advantages of combination therapy in one compound. These promising multitargeted anti-cancer compounds selectively stimulate apoptosis in cancers and also inhibit both angiogenesis and matrix metalloprotease (MMP) action in treated lung and prostate tumors in nude mice. The highly potent, metabolism-resistant bradykinin antagonist peptide dimer, B-9870 [SUIM-(DArg-Arg-Pro-Hyp-Gly-Igl-Ser-DIgl-Oic-Arg)2] (SUIM=suberimidyl; Hyp=4-hydroxyproline; Igl=alpha-(2-indanyl)glycine; Oic=octahydroindole-2-carboxylic acid) and its non-peptide mimetic, BKM-570 [2,3,4,5,6-pentafluorocinnamoyl-(o-2,6-dichlorobenzyl)-L-tyrosine-N-(4-amino-2,2,6,6-tetramethylpiperidyl)amide] are superior to the widely used but toxic chemotherapeutic drugs cisplatin and taxotere. In certain combinations, they act synergistically with standard anti-cancer drugs. Due to its structure and biological activity, BKM-570 is an attractive lead compound for derivatization and evaluation for lung and prostate cancer drugs.

The combination of topotecan and cyclophosphamide is active in relapsed Ewing sarcoma family of tumors (ESFT). The feasibility of adding these agents combined with vincristine (vincristine-topotecan-cyclophosphamide [VTc]) to standard five-drug chemotherapy with vincristine-doxorubicin-cyclophosphamide (VDC) and ifosfamide-etoposide (IE) administered in an interval-compressed (2-week instead of 3-week intervals) schedule was investigated. Newly diagnosed patients with localized ESFT < 31 years, with good performance status and adequate organ function were eligible. Seventeen alternating cycles of chemotherapy with VTc, VDC, and IE were administered at 2-week intervals. Local control (LC) of the primary tumor occurred following six cycles. Primary endpoints were the ability to deliver chemotherapy in an interval-compressed schedule, and the rate of grade 3 or greater nonhematologic toxicity and grade 4 hematologic toxicity, which delayed chemotherapy by ≥2 weeks. Secondary endpoints were event-free survival (EFS) and overall survival (OS). Thirty-five patients with a median age of 11 years were enrolled. The mean time to last dose of chemotherapy prior to LC was 12.6 ± 1.4 weeks and 45.5% of patients received intended chemotherapy without any delay prior to LC. There were no toxic deaths or unexpected toxicities. Five-year EFS was 79.6% (95% confidence interval [CI]: 61.8-89.7%) and 5-year OS was 88% (95% CI: 71.4-95.3%). The addition of VTc to standard therapy was tolerable with sufficient interval compression compared to historical standard 3-week cycles. © 2015 Wiley Periodicals, Inc.

Profile of netupitant/palonosetron (NEPA) fixed dose combination and its potential in the treatment of chemotherapy-induced nausea and vomiting (CINV)

PubMed Central

Navari, Rudolph M

2015-01-01

Chemotherapy-induced nausea and vomiting (CINV) is associated with a significant deterioration in quality of life. The emetogenicity of the chemotherapeutic agents, repeated chemotherapy cycles, and patient risk factors significantly influence CINV. The use of a combination of a 5-hydroxytryptamine-3 (5-HT3) receptor antagonists, dexamethasone, and a neurokinin-1 (NK-1) receptor antagonist has significantly improved the control of acute and delayed emesis in single-day chemotherapy. Palonosetron, a second generation 5-HT3 receptor antagonist with a different half-life, different binding capacity, and a different mechanism of action than the first generation 5-HT3 receptor antagonists, appears to be the most effective agent in its class. Netupitant, is a new NK-1 receptor antagonist with a high binding affinity, a long half-life of 90 hours, is metabolized by CYP3A4, and is an inhibitor of CYP3A4. NEPA is an oral fixed-dose combination of netupitant and palonosetron which has recently been employed in Phase II and Phase III clinical trials for the prevention of CINV in patients receiving moderately and highly emetogenic chemotherapy (MEC and HEC). The clinical trials demonstrated that NEPA (300 mg of netupitant plus 0.50 mg of palonosetron) significantly improved the prevention of CINV compared to the use of palonosetron alone in patients receiving either HEC or MEC. The clinical efficacy was maintained over multiple cycles of chemotherapy. NEPA (Akynzeo®) has recently been approved by the Food and Drug Administration (FDA) to treat nausea and vomiting in patients undergoing cancer chemotherapy. PMID:25552904

Association of cytochrome P450 genetic polymorphisms with neoadjuvant chemotherapy efficacy in breast cancer patients

PubMed Central

2012-01-01

Background The enzymes of the cytochrome P450 family (CYPs) play an important role in the metabolism of a great variety of anticancer agents; therefore, polymorphisms in genes encoding for metabolizing enzymes and drugs transporters can affect drug efficacy and toxicity. Methods The genetic polymorphisms of cytochrome P450 were studied in 395 patients with breast cancer by RLFP analysis. Results Here, we studied the association of functionally significant variant alleles of CYP3A4, CYP3A5, CYP2B6, CYP2C8, CYP2C9 and CYP2C19 with the clinical response to neoadjuvant chemotherapy in breast cancer patients. A significant correlation was observed between the CYP2C9*2 polymorphism and chemotherapy resistance (OR = 4.64; CI 95% = 1.01 – 20.91), as well as between CYP2C9*2 heterozygotes and chemotherapy resistance in women with nodal forms of breast cancer and a cancer hereditary load (OR = 15.50; CI 95% = 1.08 – 826.12) when the potential combined effects were examined. No significant association between chemotherapy resistance and the other examined genotypes and the potential combined clinical and tumour-related parameters were discovered. Conclusion In conclusion, CYP2C9*2 was associated with neoadjuvant chemotherapy resistance (OR = 4.64; CI 95% = 1.01 – 20.91) in the population of interest. PMID:22702493

Extranodal natural killer (NK)/T cell lymphoma, nasal type (ENKTL) is an aggressive non-Hodgkin lymphoma and the majority of ENKTL cases are diagnosed at the localized stage. Radiotherapy in combination with chemotherapy has been used for localized ENKTL, but the optimal combination treatment modality and the best first-line chemotherapy regimen have not been defined. In this retrospective study, 44 patients with newly diagnosed, stages I/II ENKTL were enrolled and received intensity-modulated radiation therapy (IMRT, 50-56 Gy) followed by GDP (gemcitabine, dexamethasone, and cisplatin) chemotherapy. The median number of chemotherapy cycles per patient was 4 (range, 2-6 cycles). At the end of treatment, the overall response rate was 95% (42/44), including 39 patients (89%) who attained complete response. Two patients developed systemic progression after IMRT. With a median follow-up of 37.5 months, the 3-year overall survival (OS) rate and progression-free survival (PFS) rate were 85% (95% CI, 74 to 96%) and 77% (95% CI, 64 to 91%), respectively. Locoregional and systemic failure rates for this treatment were 9% (4/44) and 14% (6/44), respectively. The most common grades 3 to 4 adverse events included leukopenia (37%), neutropenia (34%), and mucositis (25%). No treatment-related deaths were observed. This study suggested high efficacy and low toxicity of IMRT followed by GDP regimen chemotherapy for newly diagnosed stage I/II ENKTL patients. These results require further investigation in prospective trials.

Antiemetic guidelines recommend co-administration of targeted prophylactic medications inhibiting molecular pathways involved in emesis. NEPA is a fixed oral combination of a new NK 1 receptor antagonist (RA), netupitant (NETU 300 mg), and palonosetron (PALO 0.50 mg), a pharmacologically distinct 5-HT 3 RA. NEPA showed superior prevention of chemotherapy-induced nausea and vomiting (CINV) compared with oral PALO in a single chemotherapy cycle; maintenance of efficacy/safety over continuing cycles is the objective of this study. This study is a multinational, double-blind study comparing a single oral dose of NEPA vs oral PALO in chemotherapy-naïve patients receiving anthracycline/cyclophosphamide-based chemotherapy along with dexamethasone 12 mg (NEPA) or 20 mg (PALO) on day 1. The primary efficacy endpoint was delayed (25-120 h) complete response (CR: no emesis, no rescue medication) in cycle 1. Sustained efficacy was evaluated during the multicycle extension by calculating the proportion of patients with overall (0-120 h) CR in cycles 2-4 and by assessing the probability of sustained CR over multiple cycles. Of 1455 patients randomized, 1286 (88 %) participated in the multiple-cycle extension for a total of 5969 cycles; 76 % completed ≥4 cycles. The proportion of patients with an overall CR was significantly greater for NEPA than oral PALO for cycles 1-4 (74.3 vs 66.6 %, 80.3 vs 66.7 %, 83.8 vs 70.3 %, and 83.8 vs 74.6 %, respectively; p ≤ 0.001 each cycle). The cumulative percentage of patients with a sustained CR over all 4 cycles was also greater for NEPA (p < 0.0001). NEPA was well tolerated over cycles. NEPA, a convenient, guideline-consistent, fixed antiemetic combination is effective and safe over multiple cycles of chemotherapy.

Background The liver is the most common site of metastases for colorectal cancer, and combined resection with systemic chemotherapy is the most effective strategy for survival. The aim of this article is to provide a comprehensive summary on four hot topics related to chemotherapy and surgery for colorectal liver metastases (CLM), namely: (1) chemotherapy-related liver injuries: prediction and impact, (2) surgery for initially unresectable CLM, (3) the emerging role of RAS mutations, and (4) the role of hepatic arterial infusion of chemotherapy (HAIC). Summary and Key Messages (1) The use of chemotherapy before liver resection for CLM leads to drug-specific hepatic toxicity, which negatively impacts posthepatectomy outcomes. (2) Curative liver resection of initially unresectable CLM following conversion chemotherapy should be attempted whenever possible, provided that a safe future liver remnant volume is achieved. (3) For CLM, RAS mutation status is needed to guide the use of targeted chemotherapy with anti-epithelial growth factor receptor (EGFR) agents, and is a major prognostic factor that may contribute to optimize surgical strategy. (4) HAIC agents increase the rate of objective response and the rate of complete pathological response. PMID:27995091

Adjuvant therapy in early-stage non-small cell lung cancer.

Serke, Monika

Evidence clearly supports adjuvant chemotherapy following resection in patients with stage II or III non-small cell lung cancer (NSCLC). Based on 3 landmark studies, adjuvant chemotherapy has become standard in completely resected NSCLC stage II and IIIA. Survival benefit from adjuvant chemotherapy is estimated to be between 3% and 15%, depending on stage. Treatment should include 4 cycles of platinum-based combination chemotherapy. There is uncertainty about chemotherapy prescription in those patients with resected stage IB NSCLC, as the risk of recurrence is lower in early NSCLC and the magnitude of benefit of adjuvant therapy is proportional to the risk of relapse according to stage. Postoperative radiotherapy (PORT) should not be used for stage I or II NSCLC, and remains controversial in resected stage IIIA (N2) disease. All positive adjuvant trials have utilized a cisplatin-based regimen, usually in combination with vinorelbine, and this should be considered the standard approach. Prognostic factors to select patients who will benefit from adjuvant therapy in general or from platinum-based chemotherapy are under discussion, but not yet established. In future we hope to optimize treatment convenience for the patients by using other combinations with the hope of better efficacy results. Work is currently under way to identify prognostic factors which in future may help to identify patients who are most likely to benefit from chemotherapy. Copyright 2010 S. Karger AG, Basel.

Patients with advanced urothelial carcinoma that progresses after platinum-based chemotherapy have a poor prognosis and limited treatment options. In this open-label, international, phase 3 trial, we randomly assigned 542 patients with advanced urothelial cancer that recurred or progressed after platinum-based chemotherapy to receive pembrolizumab (a highly selective, humanized monoclonal IgG4κ isotype antibody against programmed death 1 [PD-1]) at a dose of 200 mg every 3 weeks or the investigator's choice of chemotherapy with paclitaxel, docetaxel, or vinflunine. The coprimary end points were overall survival and progression-free survival, which were assessed among all patients and among patients who had a tumor PD-1 ligand (PD-L1) combined positive score (the percentage of PD-L1-expressing tumor and infiltrating immune cells relative to the total number of tumor cells) of 10% or more. The median overall survival in the total population was 10.3 months (95% confidence interval [CI], 8.0 to 11.8) in the pembrolizumab group, as compared with 7.4 months (95% CI, 6.1 to 8.3) in the chemotherapy group (hazard ratio for death, 0.73; 95% CI, 0.59 to 0.91; P=0.002). The median overall survival among patients who had a tumor PD-L1 combined positive score of 10% or more was 8.0 months (95% CI, 5.0 to 12.3) in the pembrolizumab group, as compared with 5.2 months (95% CI, 4.0 to 7.4) in the chemotherapy group (hazard ratio, 0.57; 95% CI, 0.37 to 0.88; P=0.005). There was no significant between-group difference in the duration of progression-free survival in the total population (hazard ratio for death or disease progression, 0.98; 95% CI, 0.81 to 1.19; P=0.42) or among patients who had a tumor PD-L1 combined positive score of 10% or more (hazard ratio, 0.89; 95% CI, 0.61 to 1.28; P=0.24). Fewer treatment-related adverse events of any grade were reported in the pembrolizumab group than in the chemotherapy group (60.9% vs. 90.2%); there were also fewer events of grade 3, 4, or 5 severity reported in the pembrolizumab group than in the chemotherapy group (15.0% vs. 49.4%). Pembrolizumab was associated with significantly longer overall survival (by approximately 3 months) and with a lower rate of treatment-related adverse events than chemotherapy as second-line therapy for platinum-refractory advanced urothelial carcinoma.

Objective To evaluate the safety and survival in women treated with adjuvant pelvic radiation “sandwiched” between six cycles of paclitaxel and carboplatin chemotherapy with completely resected UPSC. Methods Surgically staged women with UPSC (FIGO stage 1-4) and no visible residual disease were enrolled. Treatment involved paclitaxel (175 mg/m2) and carboplatin (AUC=6.0-7.5) every 21 days for 3 doses, followed by radiation therapy (RT), followed by an additional 3 cycles of paclitaxel and carboplatin (AUC=5-6). Survival analysis, using Kaplan-Meier methods, was performed on patients who completed at least 3 cycles of chemotherapy and RT. Results A total of 81 patients were enrolled, of which 72 patients completed the first 3 cycles of chemotherapy followed by prescribed RT. Median age was 67 years (range: 43–82 years). 59/72 (82%) had disease confined to the uterus and 13/72 (18%) had completely resected extra-uterine disease (stage 3&4). 65 (83%) completed the protocol. Overall PFS and OS for combined stage 1&2 patients was 65.5±3.6 months and 76.5±4.3 months, respectively. PFS and OS for combined stage 3&4 patients was 25.8±3.0 and 35.9±5.3 months, respectively. Three-year % survival probability for stage 1&2 patients was 84% and for stage 3&4 patients was 50%. Of the 435 chemotherapy cycles administered, there were 11(2.5%) G3/G4 non-hematologic toxicities. 26(6.0%) cycles had dose reductions and 37(8.5%) had dose delays. Conclusions Compared to prior studies of single modality adjuvant therapy, RT “sandwiched” between paclitaxel and carboplatin chemotherapy is well-tolerated and highly efficacious in women with completely resected UPSC.

The aim of the study was to evaluate the efficacy of anti-angiogenic therapy with dynamic contrast-enhanced ultrasound (DCE-US) in colorectal cancer (CRC) patients with liver metastasis.A total of 50 CRC patients with liver metastasis who received bevacizumab (BEV)-based chemotherapy (BEV + FOLFOX6 protocol) were recruited into the present study. Before the study (d0), and 3, 7, 14, and 42 days (d3, d7, d14, and d42) after chemotherapy, DCE-US was performed, and tumor perfusion was evaluated quantitatively by retention time (RT), peak enhancement (PE), and wash-in area under the curve (WiAUC) on the basis of a contrast-uptake curve determined with original linear data.Routine ultrasonography was used to evaluate metastatic foci in the liver at baseline. A metastatic focus was selected for dynamic monitoring with ultrasound. The metastatic foci were 1.5 to 8 cm (median: 2.5 cm). The results of hemodynamics monitored at different time points, including RT, PE, and WiAUC, showed that RT at baseline was significantly different between groups (P < .001; Responder group: 10.54 seconds; nonresponder group: 15.33 seconds). The2 groups had opposite changes in RT (continuous increase in the responder group and transient reduction in the nonresponder). The RT of metastatic foci was normalized to that of adjacent normal liver as standard RT-quotient, a similar trend was observed, and no marked difference was noted in the standard RT-quotient between the 2 groups. The median progression-free survival was significantly higher in the increased-RT group (10.8 months) than the decreased-RT group (2.5 months) (P = .002). There were no significant differences in peak intensity and WiAUC between the 2 groups.DCE-US can be used to quantitatively evaluate the hemodynamics of liver metastasis in CRC patients who received bevacizumab-based chemotherapy.

Introduction: Increasing evidence suggests that surgical resection may be offered to a subgroup of patients with liver metastasis of gastric adenocarcinoma. The aim of this case report is to illustrate the surgical resection of a single liver metachronous recurrence twelve months after a radical total gastrectomy for cancer. Case report: A 63-year-old male patient with an Eastern Cooperative Oncology Group performance status of 1 was referred to our hospital for a single, large liver metastasis, twelve months after a radical total gastrectomy and DII lymphadenectomy for upper third gastric adenocarcinoma. As the adjuvant treatment, the patient received 12 cycles of FOLFOX chemotherapy. During the present admission, the abdominal computed tomography (CT) revealed a single liver metastasis located in the segments 5 and 6, of 105/85 mm in diameter. Surgical resection by an open approach of liver metastasis was decided. We performed a non-anatomical liver resection, without inflow control due to significant peritoneal adhesions in the liver hilum secondary to the previous lymphadenectomy. The patient was discharged after seven days, with an uneventful recovery. Six months after the second surgical procedure, the patient developed a local liver recurrence. The surgical resection of the liver recurrence was performed, with no postoperative morbidities, and the patient was discharged after eight days. Three months after the latest surgery, the patient is under adjuvant chemotherapy, with no imagistic signs of further recurrences. Conclusions:  Hepatic resection for liver metastasis of gastric origin may offer satisfactory oncological outcomes in a very selected subgroup of patients. PMID:27843732

While the risk of developing colorectal cancer increases with age, there are limited prospective data regarding best treatment in the older adult population. We launched a phase III trial to evaluate difference in treatment outcome for older adults (aged ≥70years) with advanced colorectal cancer. Here we review the challenges faced and reasons for poor accrual to N0949. We describe the conceptualization, development and limited results of N0949, a randomized phase III study of fluoropyrimidine/bevacizumab with or without oxaliplatin (mFOLFOX7 or XELOX) as first line chemotherapy for metastatic colorectal cancer. Fluoropyrimidine was physician choice (e.g., 5-FU/LV or capecitabine). Of the projected 380 patients, only 32 patients were enrolled between the study activation in January 2011 until its closure in September 2012. Reasons for poor accrual included eligibility criteria that were too stringent, discomfort with randomizing older patients to regimens of varying intensity without considering their physical fitness, and discomfort with the use of bevacizumab in the older patient population. Several efforts were mounted to design a rationale and age-appropriate study, consider toxicities and varying study practices, and be responsive to stakeholder feedback. Challenges were experienced in conducting the first prospective phase III study evaluating progression-free survival of older adults with advanced colorectal cancer receiving palliative chemotherapy with fluoropyrimidine/bevacizumab with or without oxaliplatin in the USA. Future efforts to evaluate treatment outcomes in the older adult population should reflect on lessons learned in this large national effort. Copyright © 2017 Elsevier Inc. All rights reserved.

Second-line chemotherapy in patients with advanced pancreatic ductal adenocarcinoma (PDAC) that progresses following gemcitabine-based treatment has not been established. This study aimed to investigate the efficacy and safety of second-line combination chemotherapy with capecitabine and oxaliplatin (XELOX) in these patients. Between August 2011 and May 2014, all patients who received at least one cycle of XELOX (capecitabine, 1,000 mg/m 2 twice daily for 14 days; oxaliplatin, 130 mg/m 2 on day 1 of a 3-week cycle) combination chemotherapy for unresectable or recurrent PDAC were retrospectively recruited. The response was evaluated every 9 weeks, and the tumor response rate, progression-free survival and overall survival, and adverse events were assessed. Sixty-two patients were included; seven patients (11.3%) had a partial tumor response, and 20 patients (32.3%) had stable disease. The median progression-free and overall survival were 88 days (range, 35.1 to 140.9 days) and 158 days (range, 118.1 to 197.9 days), respectively. Patients who remained stable longer with frontline therapy (≥120 days) exhibited significantly longer progression-free and overall survival. The most common grade 3 to 4 adverse events in patients were vomiting (8.1%) and anorexia (6.5%). There was one treatment-related mortality caused by severe neutropenia and typhlitis. Second-line XELOX combination chemotherapy demonstrated an acceptable response and survival rate in patients with advanced PDAC who had failed gemcitabine-based chemotherapy.

The aim of this study was to investigate the efficiency of the FOLFOX-4 regimen and to evaluate the pharmacokinetics of oxaliplatin in untreated patients with metastatic colorectal cancer. 43 patients were enrolled in the study. Patients received oxaliplatin 85 mg/m(2) as 2-h i.v. infusion, on day 1, and bolus 5-fluorouracil (5FU) 400 mg/m(2) plus leucovorin (LV) 200 mg/m(2) followed by 5FU 600 mg/m(2) as 22-h infusion on day 1 and 2, every 2 weeks. The pharmacokinetics of oxaliplatin evaluated in 4 patients was performed in blood, plasma and ultrafiltered plasma (UFT) by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The overall response rate and the median time to progression (TTP) were 53.49% and 7.1 months, respectively. Grade 3-4 toxic effects were observed in 11 (25.5%) patients. Grade 3 neuropathy was observed in 13.95% of the cases. In univariate analysis only Eastern Cooperative Oncology Group (ECOG) performance status (PS) was correlated with response. No correlation was found between grade 3-4 adverse events and the patient characteristics. The area under the time-concentration curve (AUC) in UFT was 4.8 + or - 0.72 standard deviation (SD) microg h/ml and the total clearance 30.17 + or - 7.75 l/min. The values for volume of distribution and the maximum concentration were 567 + or - 20 liters and 0.38 + or - 0.17 ug/ml, respectively. FOLFOX-4 was an effective regimen with good tolerability in previously untreated metastatic colorectal cancer patients. The pharmacokinetics of oxaliplatin was triphasic with a short initial distribution phase and a long terminal elimination phase.

Achieving complete remission (CR) in childhood relapsed/refractory acute lymphoblastic leukaemia (ALL) is a difficult task. Bortezomib, a proteasome inhibitor, has in vitro activity against ALL blasts. A phase I-II trial, reported by the Therapeutic Advances in Childhood Leukaemia and Lymphoma (TACL) consortium, demonstrated that bortezomib with chemotherapy has acceptable toxicity and remarkable activity in patients with relapsed ALL failing 2-3 previous regimens. We evaluated bortezomib in combination with chemotherapy in 30 and 7 children with B-cell precursor (BCP) and T-cell ALL, respectively. Bortezomib (1·3 mg/m 2 /dose) was administered intravenously on days 1, 4, 8, and 11. Chemotherapy agents were the same as those used in the TACL trial, consisting of dexamethasone, doxorubicin, vincristine and pegylated asparaginase. Three patients (8·1%) died due to infections. Twenty-seven patients (72·9%) achieved CR or CR with incomplete platelet recovery (CRp). Fourteen had minimal residual disease (MRD) lower than 0·1%. Twenty-two of 30 BCP-ALL patients (73·3%) and 5/7 patients (71%) with T-cell ALL achieved CR/CRp. The 2-year overall survival (OS) is 31·3%; CR/CRp patients with an MRD response had a remarkable 2-year OS of 68·4%. These data confirm that the combination of bortezomib with chemotherapy is a suitable/effective option for childhood relapsed/refractory ALL. © 2017 John Wiley & Sons Ltd.

The three-drug combination of a 5-hydroxytryptamine type 3 receptor antagonist, a neurokinin 1 receptor antagonist and dexamethasone is recommended for patients receiving highly emetogenic chemotherapy. However, standard antiemetic therapy is not completely effective in all patients. We conducted an open-label, single-center, single-arm Phase II study to evaluate the efficacy of olanzapine in combination with standard antiemetic therapy in preventing chemotherapy-induced nausea and vomiting in patients with thoracic malignancy receiving their first cycle of cisplatin-based chemotherapy. Patients received 5 mg oral olanzapine on Days 1-5 in combination with standard antiemetic therapy. The primary endpoint was complete response (no vomiting and no use of rescue therapy) during the overall Phase (0-120 h post-chemotherapy). Twenty-three men and seven women were enrolled between May and October 2015. The median age was 64 years (range: 36-75 years). The most common chemotherapy regimen was 75 mg/m2 cisplatin and 500 mg/m2 pemetrexed, which was administered to 14 patients. Complete response rates in acute (0-24 h post-chemotherapy), delayed (24-120 h post-chemotherapy) and overall phases were 100%, 83% and 83% (90% confidence interval: 70-92%; 95% confidence interval: 66-93%), respectively. There were no Grade 3 or Grade 4 adverse events. Although four patients (13%) experienced Grade 1 somnolence, no patients discontinued olanzapine. The addition of 5 mg oral olanzapine to standard antiemetic therapy demonstrates promising efficacy in preventing cisplatin-based chemotherapy-induced nausea and vomiting and an acceptable safety profile in patients with thoracic malignancy. © The Author 2017.

PurposeTo verify whether microwave ablation (MWA) used as a local control treatment had an improved outcome regarding advanced non-small cell lung cancer (NSCLC) when combined with chemotherapy.MethodsThirty-nine patients with histologically verified advanced NSCLC and at least one measurable site other than the ablative sites were enrolled. Primary tumors underwent MWA followed by platinum-based doublet chemotherapy. Modified response evaluation criteria in solid tumors (mRECIST) and RECIST were used to evaluate therapeutic response. Complications were assessed using the National Cancer Institute Common Toxicity Criteria (version 3.0).ResultsMWA was administered to 39 tumors in 39 patients. The mean and median diameters of the primarymore » tumor were 3.84 cm and 3.30 cm, respectively, with a range of 1.00–9.00 cm. Thirty-three (84.6 %) patients achieved a partial response. No correlation was found between MWA efficacy and clinicopathologic characteristics. For chemotherapy, 11 patients (28.2 %) achieved a partial response, 18 (46.2 %) showed stable disease, and 10 (25.6 %) had progressive disease. The overall objective response rate and disease control rate were 28.2 and 74.4 %, respectively. The median progression-free survival time was 8.7 months (95 % CI 5.5–11.9). The median overall survival time was 21.3 months (95 % CI 17.0–25.4). Complications were observed in 22 (56.4 %) patients, and grade 3 adverse events were observed in 3 (7.9 %) patients.ConclusionsPatients with advanced NSCLC could benefit from MWA in combination with chemotherapy. Complications associated with MWA were common but tolerable.« less

The objective of this retrospective study was to evaluate the influence of neoadjuvant systemic chemotherapy on patients with colorectal carcinomatosis before a curative procedure. Peritoneal carcinomatosis (PC) from colorectal cancer may be treated with a curative intent by cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The role of perioperative systemic chemotherapy for this particular metastatic disease remains unclear. One hundred twenty patients with PC from colorectal cancer were consecutively treated by 131 procedures combining CRS with HIPEC. The response to neoadjuvant systemic chemotherapy was assessed on data from previous explorative surgery and/or radiological imaging. Ninety patients (75%) were treated with neoadjuvant systemic chemotherapy in whom 32 (36%) were considered to have responded, 19 (21%) had stable disease, and 19 (21%) developed diseases progression. Response could not be evaluated in 20 patients (22%). On univariate analysis, the use of neoadjuvant systemic chemotherapy had a significant positive prognostic influence (P = 0.042). On multivariate analysis, the completeness of CRS and the use of adjuvant systemic chemotherapy were the only significant prognostic factors (P < 0.001 and P = 0.049, respectively). Response to neoadjuvant systemic chemotherapy had no significant prognostic impact with median survival of 31.4 months in patients showing disease progression. In patients with PC from colorectal cancer without extraperitoneal metastases, failure of neoadjuvant systemic chemotherapy should not constitute an absolute contraindication to a curative procedure combining CRS and HIPEC.

CD133 and cancer-testis antigens (CTAs) may be potential predicted markers of adjuvant chemotherapy or immune therapy, and they may be the independent prognostic factor of NSCLC. Nowadays, there is still no predictive biomarker identified for the use of adjuvant chemotherapy in non-small cell lung cancer (NSCLC) patients. To clarify the role of CD133 and CTAs as a predictive marker for adjuvant chemotherapy or prognostic factors of overall survival, we performed a retrospective study in 159 stage Ib-IIIA NSCLC patients receiving adjuvant chemotherapy or observe from April 2003 to March 2004 in our institute. Clinical data and gene anaylisis results were collected, while CD133 and three CTAs (MAGE-A4, NY-ESO-1, MAGE-A10) were determined according to their monoclonal antibodies such as CD133, 57B, D8.38 and 3GA11 by immunohistochemistry. All CTAs were more frequently expressed in squamous cell carcinoma (SCC) (50.0%, 26.9%, 34.6%) than in adenocarcinoma (16.2%, 16.2%, 16.2%). CD133 was more frequently found in patients with adenocarcinoma (P=0.044). Negative expression of CD133 was associated with a significantly longer overall survival compared to positive expression of CD133 (62.5 vs. 48.5 months, P=0.035). When combined with MAGEA4, NY-ESO-1or MAGE-A10, patients' OS showed significantly difference among different combination. (CD133-MAGEA4-/CD133-MAGEA4+/CD133+MAGEA4-/CD133+MAGEA4+: 65.6 months vs.51.5 months vs.32.2 months vs.19.8 months, P=0.000, CD133-NY-ESO-1-/ CD133+NY-ESO-1-/CD133-NY-ESO-1+/ CD133+NY-ESO-1+: 57.8 months vs. 55.7 months vs. 44.6 months vs. 28.5 months, P=0.000, CD133-MAGEA10-/CD133+ MAGEA10-/CD133-MAGEA10-/CD133+MAGEA10+: 66.2 months vs. 57.2 months vs. 48.8 months vs. 41.4 months, P=0.001). There is no difference between patients received adjuvant chemotherapy or not, but subgroup analysis showed that the patients with CD133+NY-ESO-1+ expression who received chemotherapy will survive longer than not receive adjuvant chemotherapy (received vs. not received, 52.1 vs. 27.1 months, P=0.020). In the subgroup with EGFR mutation/ALK translocation/Ros1 translocation/Ret fusion, the trend remained but without a statistically significant difference. Multivariate COX regression analysis showed that stage, CD133, CD133-MAGEA4- and CD133-NY-ESO-1- are independent prognostic factors. In conclusion, CTAs (MAGE-A4, NY-ESO-1, MAGE-A10) were more likely expressed in patients with squamous cell carcinoma and when CTAs combined with CD133, they can be better prognostic factors. Patients with CD133+NY-ESO-1+ expression may survive longer when treated with adjuvant chemotherapy, which indicates that the CD133 and CTAs might be a potential marker to guide adjuvant chemotherapy in this population.

Dipetrillo, Tom; Pricolo, Victor; Lagares-Garcia, Jorge

Purpose: To evaluate the feasibility and pathologic complete response rate of induction bevacizumab + modified infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX) 6 regimen followed by concurrent bevacizumab, oxaliplatin, continuous infusion 5-fluorouracil (5-FU), and radiation for patients with rectal cancer. Methods and Materials: Eligible patients received 1 month of induction bevacizumab and mFOLFOX6. Patients then received 50.4 Gy of radiation and concurrent bevacizumab (5 mg/kg on Days 1, 15, and 29), oxaliplatin (50 mg/m{sup 2}/week for 6 weeks), and continuous infusion 5-FU (200 mg/m{sup 2}/day). Because of gastrointestinal toxicity, the oxaliplatin dose was reduced to 40 mg/m{sup 2}/week. Resection was performedmore » 4-8 weeks after the completion of chemoradiation. Results: The trial was terminated early because of toxicity after 26 eligible patients were treated. Only 1 patient had significant toxicity (arrhythmia) during induction treatment and was removed from the study. During chemoradiation, Grade 3/4 toxicity was experienced by 19 of 25 patients (76%). The most common Grade 3/4 toxicities were diarrhea, neutropenia, and pain. Five of 25 patients (20%) had a complete pathologic response. Nine of 25 patients (36%) developed postoperative complications including infection (n = 4), delayed healing (n = 3), leak/abscess (n = 2), sterile fluid collection (n = 2), ischemic colonic reservoir (n = 1), and fistula (n = 1). Conclusions: Concurrent oxaliplatin, bevacizumab, continuous infusion 5-FU, and radiation causes significant gastrointestinal toxicity. The pathologic complete response rate of this regimen was similar to other fluorouracil chemoradiation regimens. The high incidence of postoperative wound complications is concerning and consistent with other reports utilizing bevacizumab with chemoradiation before major surgical resections.« less

BACKGROUND Patients with advanced urothelial carcinoma that progresses after platinum-based chemotherapy have a poor prognosis and limited treatment options. METHODS In this open-label, international, phase 3 trial, we randomly assigned 542 patients with advanced urothelial cancer that recurred or progressed after platinum-based chemotherapy to receive pembrolizumab (a highly selective, humanized monoclonal IgG4κ isotype antibody against programmed death 1 [PD-1]) at a dose of 200 mg every 3 weeks or the investigator’s choice of chemotherapy with paclitaxel, docetaxel, or vinflunine. The coprimary end points were overall survival and progression-free survival, which were assessed among all patients and among patients who had a tumor PD-1 ligand (PD-L1) combined positive score (the percentage of PD-L1–expressing tumor and infiltrating immune cells relative to the total number of tumor cells) of 10% or more. RESULTS The median overall survival in the total population was 10.3 months (95% confidence interval [CI], 8.0 to 11.8) in the pembrolizumab group, as compared with 7.4 months (95% CI, 6.1 to 8.3) in the chemotherapy group (hazard ratio for death, 0.73; 95% CI, 0.59 to 0.91; P=0.002). The median overall survival among patients who had a tumor PD-L1 combined positive score of 10% or more was 8.0 months (95% CI, 5.0 to 12.3) in the pembrolizumab group, as compared with 5.2 months (95% CI, 4.0 to 7.4) in the chemotherapy group (hazard ratio, 0.57; 95% CI, 0.37 to 0.88; P=0.005). There was no significant between-group difference in the duration of progression-free survival in the total population (hazard ratio for death or disease progression, 0.98; 95% CI, 0.81 to 1.19; P=0.42) or among patients who had a tumor PD-L1 combined positive score of 10% or more (hazard ratio, 0.89; 95% CI, 0.61 to 1.28; P =0.24). Fewer treatment-related adverse events of any grade were reported in the pembrolizumab group than in the chemotherapy group (60.9% vs. 90.2%); there were also fewer events of grade 3, 4, or 5 severity reported in the pembrolizumab group than in the chemotherapy group (15.0% vs. 49.4%). CONCLUSIONS Pembrolizumab was associated with significantly longer overall survival (by approximately 3 months) and with a lower rate of treatment-related adverse events than chemotherapy as second-line therapy for platinum-refractory advanced urothelial carcinoma.

Seven cases of soft tissue sarcoma developing after primary or postoperative radiotherapy for breast carcinoma are reported. The sarcomas occurred within the irradiated volume, after a latent period of 4-26 years. These cases conform well to established criteria for the diagnosis of radiation-induced sarcoma. Chemotherapy, consisting of the four-drug combination CYVADIC (cyclophosphamide, vincristine, adriamycin, DTIC) was employed in six of the seven patients. Only two of them achieved partial remission, lasting only 2 and 3 months, respectively. The effectiveness of adriamycin-containing chemotherapy regimens in soft tissue sarcomas as well as the remote hazard of radiation-related sarcoma in primary or postoperativemore » breast irradiation are discussed.« less

Autophagy is an important oncotarget that can be modulated during anti-cancer therapy. Enhancing autophagy using chemotherapy and rapamycin (Rapa) treatment and then inhibiting it using hydroxychloroquine (HCQ) could synergistically improve therapy outcome in cancer patients. It is still unclear whether addition of Rapa and HCQ to chemotherapy could be used for reversing drug resistance. Twenty-five stage IV cancer patients were identified. They had no clinical response to first-line metronomic chemotherapy; the patients were salvaged by adding an autophagy inducer (Rapa, 2 mg/day) and an autophagosome inhibitor (HCQ, 400 mg/day) to their current metronomic chemotherapy for at least 3 months. Patients included 4 prostate, 4 bladder, 4 lung, 4 breast, 2 colon, and 3 head and neck cancer patients as well as 4 sarcoma patients. Chemotherapy was administered for a total of 137 months. The median duration of chemotherapy cycles per patient was 4 months (95% confidence interval, 3-7 months). The overall response rate to this treatment was of 40%, with an 84% disease control rate. The most frequent and clinically significant toxicities were myelotoxicities. Grade ≥3 leucopenia occurred in 6 patients (24%), grade ≥3 thrombocytopenia in 8 (32%), and anemia in 3 (12%). None of them developed febrile neutropenia. Non-hematologic toxicities were fatigue (total 32%, with 1 patient developing grade 3 fatigue), diarrhea (total 20%, 1 patient developed grade 3 fatigue), reversible grade 3 cardiotoxicity (1 patient), and grade V liver toxicity from hepatitis B reactivation (1 patient). Our results of Rapa, HCQ and chemotherapy triplet combination suggest autophagy is a promising oncotarget and warrants further investigation in phase II studies.

Since there is no 100% satisfactory treatment for localized prostate cancer in patients presenting symptoms representing a poor prognosis (stage T3, high Gleason score, PSA level greater than 15 ng/ml, etc.), this study aimed to evaluate the therapeutic and synergistic inhibition effects of using High Intensity Focused Ultrasound (HIFU) in combination with chemotherapy (Taxane + Estramustine). Forty-one Dunning AT2 tumour-bearing Copenhagen rats receiving HIFU and/or chemotherapy were divided into four groups: control group; chemotherapy group; HIFU group; and HIFU-chemotherapy combined group. Increase in the tumour volume was observed over 3 weeks and the tumour volume doubling time was evaluated. Growth curves for each group were then plotted and statistically evaluated. HIFU treatment combined with Taxane + Estramusine was found to have a significant synergistic effect; on day 30, the distribution of tumour volume relative to the treatment group was significantly different (p = 0.0007). The control group volumes were significantly greater than those of the chemotherapy-only (p = 0.006) or HIFU-only group (p = 0.006). The greatest difference was observed between the chemotherapy plus HIFU combined group and the control group. Additionally, tumour-doubling times were 7.7 days for the control group, 13.2 days for the HIFU-only group, and 31.2 days for the chemotherapy plus HIFU group. The differences in tumour growth rates between the chemotherapy plus HIFU combined group and a chemotherapy-only + HIFU-only grouping was 3.8% (p = 0.0020). Thus, the combined chemotherapy plus HIFU treatment was clearly more effective in reducing the tumour size than HIFU only or chemotherapy only, which indicates a synergy between the two types of treatment. Our results suggest that this combined therapy could be useful for the treatment of high-risk prostate cancer.

In platinum-resistant ovarian cancer (OC), single-agent chemotherapy is standard. Bevacizumab is active alone and in combination. AURELIA is the first randomized phase III trial to our knowledge combining bevacizumab with chemotherapy in platinum-resistant OC. Eligible patients had measurable/assessable OC that had progressed < 6 months after completing platinum-based therapy. Patients with refractory disease, history of bowel obstruction, or > two prior anticancer regimens were ineligible. After investigators selected chemotherapy (pegylated liposomal doxorubicin, weekly paclitaxel, or topotecan), patients were randomly assigned to single-agent chemotherapy alone or with bevacizumab (10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks) until progression, unacceptable toxicity, or consent withdrawal. Crossover to single-agent bevacizumab was permitted after progression with chemotherapy alone. The primary end point was progression-free survival (PFS) by RECIST. Secondary end points included objective response rate (ORR), overall survival (OS), safety, and patient-reported outcomes. The PFS hazard ratio (HR) after PFS events in 301 of 361 patients was 0.48 (95% CI, 0.38 to 0.60; unstratified log-rank P < .001). Median PFS was 3.4 months with chemotherapy alone versus 6.7 months with bevacizumab-containing therapy. RECIST ORR was 11.8% versus 27.3%, respectively (P = .001). The OS HR was 0.85 (95% CI, 0.66 to 1.08; P < .174; median OS, 13.3 v 16.6 months, respectively). Grade ≥ 2 hypertension and proteinuria were more common with bevacizumab. GI perforation occurred in 2.2% of bevacizumab-treated patients. Adding bevacizumab to chemotherapy statistically significantly improved PFS and ORR; the OS trend was not significant. No new safety signals were observed.

There is no standard therapy for relapsed patients who have received postoperative platinum-based adjuvant chemotherapy for resected non-small-cell lung cancer (NSCLC). We investigated the efficacy and safety of platinum combination chemotherapy re-challenge for such patients. Medical records from 3 institutes from April 2005 to July 2012 were retrospectively reviewed. Patients who underwent complete surgical resection were eligible if they received postoperative adjuvant chemotherapy consisting of cisplatin plus vinorelbine once and then re-challenge with platinum combination chemotherapy. Sixteen patients were enrolled in this study. After re-challenge with platinum combination chemotherapy, we observed an overall response rate of 31.2% (5/16) and a disease control rate of 81.2% (13/16). Median progression-free survival and overall survival from the start of the re-administration of platinum combination chemotherapy were 6.5 and 28.0 months, respectively. Frequently observed severe adverse events (≥grade 3) included neutropenia (31.2%), thrombocytopenia (31.2%), leukopenia (12.5%) and hyponatremia (12.5%). Frequently observed non-hematological toxicities (≥grade 2) were anorexia (37.5%) and nausea (37.5%). Re-challenge with platinum combination chemotherapy was effective and safe; therefore, this therapy should be considered as a treatment option for relapsed patients after postoperative cisplatin-based adjuvant chemotherapy for resected NSCLC. © 2014 S.

Single-agent taxanes are commonly used as salvage systemic therapy for patients with advanced urothelial carcinoma (UC). To study the impact of combination chemotherapy delivering a taxane plus other chemotherapeutic agents compared with single-agent taxane as salvage therapy. Individual patient-level data from phase 2 trials of salvage systemic therapy were used. Trials evaluating either single agents (paclitaxel or docetaxel) or combination chemotherapy (taxane plus one other chemotherapeutic agent or more) following prior platinum-based therapy were used. Information regarding the known major baseline prognostic factors was required: time from prior chemotherapy, hemoglobin, performance status, albumin, and liver metastasis status. Cox proportional hazards regression was used to evaluate the association of prognostic factors and combination versus single-agent chemotherapy with overall survival (OS). Data were available from eight trials including 370 patients; two trials (n=109) evaluated single-agent chemotherapy with docetaxel (n=72) and cremophor-free paclitaxel (n=37), and six trials (n=261) evaluated combination chemotherapy with gemcitabine-paclitaxel (two trials, with n=99 and n=24), paclitaxel-cyclophosphamide (n=32), paclitaxel-ifosfamide-nedaplatin (n=45), docetaxel-ifosfamide-cisplatin (n=26), and paclitaxel-epirubicin (n=35). On multivariable analysis after adjustment for baseline prognostic factors, combination chemotherapy was independently and significantly associated with improved OS (hazard ratio: 0.60; 95% confidence interval, 0.45-0.82; p=0.001). The retrospective design of this analysis and the trial-eligible population were inherent limitations. Patients enrolled in trials of combination chemotherapy exhibited improved OS compared with patients enrolled in trials of single-agent chemotherapy as salvage therapy for advanced UC. Prospective randomized trials are required to validate a potential role for rational and tolerable combination chemotherapeutic regimens for the salvage therapy of advanced UC. This retrospective study suggests that a combination of chemotherapy agents may extend survival compared with single-agent chemotherapy in selected patients with metastatic urothelial cancer progressing after prior chemotherapy.

Peripheral sensory neuropathy is the most prominently reported adverse effect of oxaliplatin. The purpose of this study was to evaluate metformin role in oxaliplatin-induced neuropathy. From November 2014 to May 2016, 40 patients with stage III colorectal cancer completed 12 cycles of FOLFOX-4 regimen. Twenty patients in the control arm received FOLFOX-4 regimen only, and 20 patients in the metformin arm, received the same regimen along with metformin 500 mg three times daily. The metformin efficacy was evaluated using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE version 4.0), a12-item neurotoxicity questionnaire (Ntx-12) from the validated Functional Assessment of Cancer Therapy/Gynecologic Oncology Group and, the brief pain inventory short form "worst pain" item. In addition to neurotensin, malondialdehyde and interleukin-6 serum levels assessment. At the end of the 12th cycle, there were less patients with grade 2 and 3 neuropathy in metformin arm as compared to control arm. (60 versus 95%, P = 0.009) In addition, metformin arm showed significantly higher total scores of Ntx-12 questionnaire than control arm (24.0 versus 19.2, P < 0.001). Furthermore, the mean pain score in metformin arm was significantly lower than those of control arm, (6.7 versus 7.3, P = 0.005). Mean serum levels of malondialdehyde and neurotensin were significantly lower in metformin arm after the 6th and the 12th cycles. Metformin may be a promising drug in protecting colorectal cancer patients against oxaliplatin-induced chronic peripheral sensory neuropathy.

Both perioperative chemotherapy and postoperative chemoradiotherapy improve survival in patients with resectable gastric cancer from Europe and North America. To our knowledge, these treatment strategies have not been investigated in a head to head comparison. We aimed to compare perioperative chemotherapy with preoperative chemotherapy and postoperative chemoradiotherapy in patients with resectable gastric adenocarcinoma. In this investigator-initiated, open-label, randomised phase 3 trial, we enrolled patients aged 18 years or older who had stage IB- IVA resectable gastric or gastro-oesophageal adenocarcinoma (as defined by the American Joint Committee on Cancer, sixth edition), with a WHO performance status of 0 or 1, and adequate cardiac, bone marrow, liver, and kidney function. Patients were enrolled from 56 hospitals in the Netherlands, Sweden, and Denmark, and were randomly assigned (1:1) with a computerised minimisation programme with a random element to either perioperative chemotherapy (chemotherapy group) or preoperative chemotherapy with postoperative chemoradiotherapy (chemoradiotherapy group). Randomisation was done before patients were given any preoperative chemotherapy treatment and was stratified by histological subtype, tumour localisation, and hospital. Patients and investigators were not masked to treatment allocation. Surgery consisted of a radical resection of the primary tumour and at least a D1+ lymph node dissection. Postoperative treatment started within 4-12 weeks after surgery. Chemotherapy consisted of three preoperative 21-day cycles and three postoperative cycles of intravenous epirubicin (50 mg/m 2 on day 1), cisplatin (60 mg/m 2 on day 1) or oxaliplatin (130 mg/m 2 on day 1), and capecitabine (1000 mg/m 2 orally as tablets twice daily for 14 days in combination with epirubicin and cisplatin, or 625 mg/m 2 orally as tablets twice daily for 21 days in combination with epirubicin and oxaliplatin), received once every three weeks. Chemoradiotherapy consisted of 45 Gy in 25 fractions of 1·8 Gy, for 5 weeks, five daily fractions per week, combined with capecitabine (575 mg/m 2 orally twice daily on radiotherapy days) and cisplatin (20 mg/m 2 intravenously on day 1 of each 5 weeks of radiation treatment). The primary endpoint was overall survival, analysed by intention-to-treat. The CRITICS trial is registered at ClinicalTrials.gov, number NCT00407186; EudraCT, number 2006-004130-32; and CKTO, 2006-02. Between Jan 11, 2007, and April 17, 2015, 788 patients were enrolled and randomly assigned to chemotherapy (n=393) or chemoradiotherapy (n=395). After preoperative chemotherapy, 372 (95%) of 393 patients in the chemotherapy group and 369 (93%) of 395 patients in the chemoradiotherapy group proceeded to surgery, with a potentially curative resection done in 310 (79%) of 393 patients in the chemotherapy group and 326 (83%) of 395 in the chemoradiotherapy group. Postoperatively, 233 (59%) of 393 patients started chemotherapy and 245 (62%) of 395 started chemoradiotherapy. At a median follow-up of 61·4 months (IQR 43·3-82·8), median overall survival was 43 months (95% CI 31-57) in the chemotherapy group and 37 months (30-48) in the chemoradiotherapy group (hazard ratio from stratified analysis 1·01 (95% CI 0·84-1·22; p=0·90). After preoperative chemotherapy, in the total safety population of 781 patients (assessed together), there were 368 (47%) grade 3 adverse events; 130 (17%) grade 4 adverse events, and 13 (2%) deaths. Causes of death during preoperative treatment were diarrhoea (n=2), dihydropyrimidine deficiency (n=1), sudden death (n=1), cardiovascular events (n=8), and functional bowel obstruction (n=1). During postoperative treatment, grade 3 and 4 adverse events occurred in 113 (48%) and 22 (9%) of 233 patients in the chemotherapy group, respectively, and in 101 (41%) and ten (4%) of 245 patients in the chemoradiotherapy group, respectively. Non-febrile neutropenia occurred more frequently during postoperative chemotherapy (79 [34%] of 233) than during postoperative chemoradiotherapy (11 [4%] of 245). No deaths were observed during postoperative treatment. Postoperative chemoradiotherapy did not improve overall survival compared with postoperative chemotherapy in patients with resectable gastric cancer treated with adequate preoperative chemotherapy and surgery. In view of the poor postoperative patient compliance in both treatment groups, future studies should focus on optimising preoperative treatment strategies.

To determine survival time for dogs with splenic hemangiosarcoma treated with splenectomy alone, identify potential prognostic factors, and evaluate the efficacy of adjuvant chemotherapy. Retrospective case series. 208 dogs. Medical records were reviewed, long-term follow-up information was obtained, and survival data were analyzed statistically. 154 dogs were treated with surgery alone, and 54 were treated with surgery and chemotherapy. Twenty-eight dogs received conventional chemotherapy, 13 received cyclophosphamide-based metronomic chemotherapy, and 13 received both conventional and metronomic chemotherapy. Median survival time of dogs treated with splenectomy alone was 1.6 months. Clinical stage was the only prognostic factor significantly associated with survival time. When the entire follow-up period was considered, there was no significant difference in survival time between dogs treated with surgery alone and dogs treated with surgery and chemotherapy. However, during the first 4 months of follow-up, after adjusting for the effects of clinical stage, survival time was significantly prolonged among dogs receiving any type of chemotherapy (hazard ratio, 0.6) and among dogs receiving both conventional and metronomic chemotherapy (hazard ratio, 0.4). Clinical stage was strongly associated with prognosis for dogs with splenic hemangiosarcoma. Chemotherapy was effective in prolonging survival time during the early portion of the follow-up period. Combinations of doxorubicin-based conventional protocols and cyclophosphamide-based metronomic protocols appeared to be more effective than either type of chemotherapy alone, but prolongations in survival time resulting from current protocols were modest.

Objective A network meta-analysis was conducted comparing the short-term efficacies of 16 targeted drugs in combination with chemotherapy for treatment of advanced/metastatic colorectal cancer (CRC). Results Twenty-seven RCTs were ultimately incorporated into this network meta-analysis. Compared with chemotherapy alone, bevacizumab + chemotherapy, panitumumab + chemotherapy and conatumumab + chemotherapy had higher PR rate. Bevacizumab + chemotherapy, cetuximab + chemotherapy, panitumumab + chemotherapy, trebananib + chemotherapy and conatumumab + chemotherapy had higher ORR rate in comparison to chemotherapy alone. Furthermore, bevacizumab + chemotherapy had higher DCR rate than chemotherapy alone. The results of our cluster analysis showed that chemotherapy combined with bevacizumab, cetuximab, panitumumab, conatumumab, ganitumab, or brivanib + cetuximab had better efficacies for the treatment of advanced/metastatic CRC in comparison to chemotherapy alone. Materials and Methods Electronic databases were comprehensively searched for potential and related randomized controlled trials (RCTs). Direct and indirect evidence were incorporated for evaluation of stable disease (SD), progressive disease (PD), complete response (CR), partial response (PR), disease control rate (DCR) and overall response ratio (ORR) by calculating odds ratio (OR) and 95% confidence intervals (CI), and using the surface under the cumulative ranking curve (SUCRA). Conclusions These results indicated that bevacizumab + chemotherapy, panitumumab + chemotherapy, conatumumab + chemotherapy and brivanib + cetuximab + chemotherapy may have better efficacies for the treatment of advanced/metastatic CRC.

A total of 15 patients with relapsed or resistant Hodgkin's disease were treated with a combination of etoposide (VP16), ifosfamide, mitozantrone and dexamethasone (VIM-D). The regime was well tolerated, the only major toxicity being myelosuppression. Complete remissions (CRs) were obtained in 4 patients and were maintained for 2, 4, 10 and 14 months. 10 subjects subsequently received an autologous bone marrow transplant with high-dose chemotherapy (ABMT). Previous exposure to VIM-D did not appear to predict for or prejudice the response to subsequent ABMT.

We have experienced 4 cases of therapy-related leukemia (TRL) in 119 patients with multiple myeloma (MM) who had received combination chemotherapy including alkylating agents between 1988 and 1998. All 4 cases were acute myelogenous leukemia, 3 were males and 1 was female. Median age at diagnosis of MM was 60 years, and median time to TRL from diagnosis of MM was 5.5 years. The chromosome abnormalities were found in 3 of those cases. All 4 cases were resistant to antileukemic chemotherapy, and median survival time from TRL was only 5.5 months. The TRL in MM is thought to be a more important problem, because recently the treatment for this disease has become more intensive, including high-dose chemotherapy supported by autologous stem cell transplantation.

Radiation combined with chemotherapy has recently been proposed to treat patients with localised extranodal natural killer (NK)/T lymphoma (ENKTL), nasal type. However, the modalities of the chemoradiotherapy combination and drug choices remain a matter of debate. We conducted a concurrent chemoradiotherapy (CCRT) study with the ESHAP (Etoposide, Steroid, High-dose Ara-C and Platinum) regimen. An induction phase with two upfront courses of CCRT delivering a 40Gy dose of radiation concurrently with two cycles of the ESHAP chemotherapy regimen, followed by a consolidation phase with 2-3 cycles of ESHAP chemotherapy alone. Thirteen patients with localised ENKTL nasal type were enrolled between January 2005 and December 2014. The median age was 62years. Ten and three patients had Ann Arbor stage IE and IIE disease, respectively. They all completed the induction CCRT phase. A median of two consolidation ESHAP cycles were delivered. During consolidation, 8/13 (62%) patients had a reduction in the number of chemotherapy cycles or reduced chemotherapy doses, due to haematologically adverse events. The other five patients (38%) received the full number of ESHAP cycles of chemotherapy scheduled without a dose reduction. All but one patient (92%) experienced grade 3-4 haematological toxicity. The main non-haematological grade 3-4 toxicity was mucositis in 6/13 (46%) patients. All but one patient (92%) achieved a complete remission. Two-year overall survival was 72%. With optimal management of the specific toxicities induced by this treatment modality, CCRT with the ESHAP regimen yielded high efficacy against localised ENKTL, nasal type.

Treatment of patients with non-metastatic, locally advanced rectal cancer (LARC) includes pre-operative chemoradiation, total mesorectal excision (TME) and post-operative adjuvant chemotherapy. This trimodality treatment provides local tumor control in most patients; but almost one-third ultimately die from distant metastasis. Most survivors experience significant impairment in quality of life (QoL), due primarily to removal of the rectum. A current challenge lies in identifying patients who could safely undergo rectal preservation without sacrificing survival benefit and QoL. This multi-institutional, phase II study investigates the efficacy of total neoadjuvant therapy (TNT) and selective non-operative management (NOM) in LARC. Patients with MRI-staged Stage II or III rectal cancer amenable to TME will be randomized to receive FOLFOX/CAPEOX: a) before induction neoadjuvant chemotherapy (INCT); or b) after consolidation neoadjuvant chemotherapy (CNCT), with 5-FU or capecitabine-based chemoradiation. Patients in both arms will be re-staged after completing all neoadjuvant therapy. Those with residual tumor at the primary site will undergo TME. Patients with clinical complete response (cCR) will receive non-operative management (NOM). NOM patients will be followed every 3 months for 2 years, and every 6 months thereafter. TME patients will be followed according to NCCN guidelines. All will be followed for at least 5 years from the date of surgery or--in patients treated with NOM--the last day of treatment. The studies published thus far on the safety of NOM in LARC have compared survival between select groups of patients with a cCR after NOM, to patients with a pathologic complete response (pCR) after TME. The current study compares 3-year disease-free survival (DFS) in an entire population of patients with LARC, including those with cCR and those with pCR. We will compare the two arms of the study with respect to organ preservation at 3 years, treatment compliance, adverse events and surgical complications. We will measure QoL in both groups. We will analyze molecular indications that may lead to more individually tailored treatments in the future. This will be the first NOM trial utilizing a regression schema for response assessment in a prospective fashion. NCT02008656.

Pembrolizumab is a humanized monoclonal antibody which serves to enhance the antitumor immune response by targeting programmed cell death 1 receptor. The use of pembrolizumab plus carboplatin/pemetrexed combination therapy results in improvement in overall survival and progression-free survival rates for non-small cell lung cancer (NSCLC) patients as compared to chemotherapy alone. However, numerous immune-mediated toxicities of pembrolizumab have been reported. We report the case of a 74-year-old male patient diagnosed with stage IIIA programmed death-ligand 1-positive non-small cell lung adenocarcinoma treated with 4 cycles of carboplatin/pemetrexed plus pembrolizumab combination therapy followed by 2 cycles of pembrolizumab treatment. Follow-up PET-CT scanning showed a very good response at the level of the tumor but new-onset activity in bilateral hilar and mediastinal lymph nodes. Biopsy of these lymph nodes revealed a benign pathology with noncaseating granulomas consistent with immune-mediated sarcoidosis. The pathogenesis of immunotherapy-induced sarcoidosis is not yet known but has been reported in different cancers and using different checkpoint inhibitors. To our knowledge, this case is the first in the literature displaying pulmonary sarcoidosis in a patient with NSCLC 4 months after having initiated chemotherapy plus pembrolizumab combination therapy.

Radiation recall gastritis is rare but can be induced after concurrent chemoradiation for pancreatic cancer. We report a patient with pancreatic cancer who developed radiation-recall gastritis related to a combination of gemcitabine and erlotinib. A 54-year-old female with unresectable pancreatic cancer received gemcitabine in combination with radiation therapy followed by chemotherapy with gemcitabine and erlotinib. After completing 2 cycles of chemotherapy, the patient had epigastric pain, nausea, and vomiting. Abdominal computed tomography (CT) scan revealed diffuse wall thickening of the stomach, and esophagogastroduodenoscopy (EGD) showed multiple gastric ulcers. The patient was treated with proton pump inhibitors (PPI) and was continued on maintenance chemotherapy. Two months later, the patient presented with the similar symptoms and persistent gastric ulcers were observed during subsequent EGD. Nevertheless, the patient's symptom had resolved with PPI therapy. Thus, the patient underwent maintenance chemotherapy with gemcitabine and erlotinib for additional 4 cycles. Eventually, follow-up abdominal CT Scan and EGD at 6 months demonstrated resolution of the gastric ulcers. Physicians should be aware of the possibility of radiation recall gastritis associated with a combination of gemcitabine and erlotinib. Administration of PPIs may mitigate the adverse effects of gemcitabine and erlotinib in the presence of radiation recall gastritis; however further studies are warranted.

Circulating protein markers were assessed in patients with colorectal cancer (CRC) treated with cetuximab in CALGB 80203 to identify prognostic and predictive biomarkers. Patients with locally advanced or metastatic CRC received FOLFOX or FOLFIRI chemotherapy (chemo) or chemo in combination with cetuximab. Baseline plasma samples from 152 patients were analyzed for six candidate markers [epidermal growth factor (EGF), heparin-binding EGF (HBEGF), epidermal growth factor receptor (EGFR), HER2, HER3, and CD73]. Analyte levels were associated with survival endpoints using univariate Cox proportional hazards models. Predictive markers were identified using a treatment-by-marker interaction term in the Cox model. Plasma levels of EGF, HBEGF, HER3, and CD73 were prognostic for overall survival (OS) across all patients (KRAS mutant and wild-type). High levels of EGF predicted for lack of OS benefit from cetuximab in KRAS wild-type (WT) patients (chemo HR = 0.98, 95% CI = 0.74-1.29; chemo+cetuximab HR = 1.54, 95% CI = 1.05-2.25; interaction P = 0.045) and benefit from cetuximab in KRAS mutant patients (chemo HR = 1.72, 95% CI = 1.02-2.92; chemo+cetuximab HR = 0.90, 95% CI = 0.67-1.21; interaction P = 0.026). Across all patients, higher HER3 levels were associated with significant OS benefit from cetuximab treatment (chemo HR = 4.82, 95% CI = 1.68-13.84; chemo+cetuximab HR = 0.95, 95% CI = 0.31-2.95; interaction P = 0.046). CD73 was also identified as predictive of OS benefit in KRAS WT patients (chemo HR = 1.28, 95% CI = 0.88-1.84; chemo+cetuximab HR = 0.60, 95% CI = 0.32-1.13; interaction P = 0.049). Although these results are preliminary, and confirmatory studies are necessary before clinical application, the data suggest that HER3 and CD73 may play important roles in the biological response to cetuximab. © 2016 The Authors.

The combination of all-trans retinoic acid (ATRA) and arsenic trioxide (As2O3, ATO) has been effective in obtaining high clinical complete remission (CR) rates in acute promyelocytic leukemia (APL), but the long-term efficacy and safety among newly diagnosed APL patients are unclear. In this retrospective study, total 45 newly diagnosed APL patients received ATRA/chemotherapy combination regimen to induce remission. Among them, 43 patients (95.6%) achieved complete remission (CR) after induction therapy, followed by ATO/ATRA/anthracycline-based chemotherapy sequential consolidation treatment with a median follow-up of 55 months. In these patients, the estimated overall survival (OS) and the relapse-free survival (RFS) were 94.4% ± 3.9% and 94.6 ± 3.7%, respectively. The toxicity profile was mild and reversible. No secondary carcinoma was observed. These results demonstrated the high efficacy and minimal toxicity of ATO/ATRA/anthracycline-based chemotherapy sequential consolidation treatment for newly diagnosed APL in long-term follow-up, suggesting a potential frontline therapy for APL.

Objective. To evaluate the therapeutic effects of Disodium Pamidronate (Bonin) on bone pain in multiple myeloma. Method. 18 patients received only chemotherapy and 16 patients with addition of Bonin were compared. Result. The bone pain was significantly relieved both in chemotherapy alone group and in the combination group of Bonin with chemotherapy after treatment (P<0.01, as compared with before therapy). However, the effects of combination group were more dramatical than that of the other group (P<0.05). No obvious side-effects were observed except mild fever in one patient in the combination group. Conclusion. Bonin, as a safe and effective Bisphosphonates preparation, could relieve bone pain in multiple myeloma more effectively when combined with chemotherapy.

Outcome of HIV-infected patients with AIDS-related lymphomas has improved during recent years. However, data on incidence, risk factors, and outcome of relapses in AIDS-related lymphomas after achieving complete remission are still limited. This prospective observational multicenter study includes HIV-infected patients with biopsy- or cytology-proven malignant lymphomas since 2005. Data on HIV infection and lymphoma characteristics, treatment and outcome were recorded. For this analysis, AIDS-related lymphomas patients in complete remission were analyzed in terms of their relapse- free survival and potential risk factors for relapses. In total, 254 of 399 (63.7%) patients with AIDS-related lymphomas reached a complete remission with their first-line chemotherapy. After a median follow up of 4.6 years, 5-year overall survival of the 254 patients was 87.8% (Standard Error 3.1%). Twenty-nine patients relapsed (11.4%). Several factors were independently associated with a higher relapse rate, including an unclassifiable histology, a stage III or IV according to the Ann Arbor Staging System, no concomitant combined antiretroviral therapy during chemotherapy and R-CHOP-based compared to more intensive chemotherapy regimens in Burkitt lymphomas. In conclusion, complete remission and relapse rates observed in our study are similar to those reported in HIV-negative non-Hodgkin lymphomas. These data provide further evidence for the use of concomitant combined antiretroviral therapy during chemotherapy and a benefit from more intensive chemotherapy regimens in Burkitt lymphomas. Modifications to the chemotherapy regimen appear to have only a limited impact on relapse rate. Copyright © 2018 Ferrata Storti Foundation.

Chemotherapy-induced neutropenia is a common complication in cancer treatment. In this study, we investigated chemotherapy-induced neutropenia that was recently detected in all patients with gynecologic malignancy. Between January 2009 and December 2011, we examined cases of chemotherapy-induced neutropenia reported in our hospital. We analyzed the incidence and clinical features of chemotherapy-induced neutropenia and febrile neutropenia in patients with gynecologic malignancy. During the study period, we administered over 1614 infusions (29 regimens) to 291 patients. The median age of the patients was 60 years (range 24–84 years). Chemotherapy-induced neutropenia occurred in 147 (50.5%) patients over 378 (23.4%) chemotherapy cycles. Febrile neutropenia occurred in 20 (6.9%) patients over 25 (1.5%) cycles. The mean duration of neutropenia and fever was 3.6 days (range 1–12 days) and 3.4 days (range 1–9 days), respectively. The source of fever was unexplained by examination or cultures in 14 (56.0%) cycles. There were two cases of neutropenia-related death. Chemotherapy-induced neutropenia was associated with older age (over 70 years) (P<0.0001), less than five previous chemotherapy cycles (P=0.02), disseminated disease (P=0.03), platinum-based regimens (P<0.0001), taxane-containing regimens (P<0.0001), and combined therapy (P<0.0001). Febrile neutropenia was associated with poor performance status (P<0.0001), no previous chemotherapy (P<0.05), disseminated disease (P<0.0001), and distant metastatic disease (P=0.03). Neither chemotherapy-induced neutropenia nor febrile neutropenia was associated with bone marrow metastases or previous radiotherapy. By identifying risk factors for febrile neutropenia, such as performance status, no previous chemotherapy, disseminated disease, and distant metastatic disease, the safe management of chemotherapy-induced neutropenia may be possible in patients with gynecologic malignancy.

A 67-year-old woman with debilitation and massive ascites was admitted to our hospital and diagnosed with stage IV scirrhous gastric cancer with peritoneal dissemination. After successful nasojejunal tube feeding because of oral intake disability, TS-1 combined with paclitaxel chemotherapy was selected. TS-1 at 80mg/m2 was given daily via nasojejunal tube for 2 weeks, followed by a 1-week rest, and paclitaxel at 50mg/m2 was administered intravenously on day 1 and 8. There were no serious side effects. After 4 cycles, a partial response was observed and percutaneous transesophageal gastrotubing (PTEG) was placed. After the fifth cycle, she was transferred to her home and received chemotherapy in an outpatient clinic. After 7 cycles, the disease progressed, and TS-1 combined with low-dose cisplatin was administered for 3 cycles. However, the patient died 16 weeks after discharge. PTEG was useful not only for a route of TS-1 administration, but also for receiving chemotherapy at home to maintain her quality.

The interaction of acute myeloid leukemia (AML) blasts with the leukemic microenvironment is postulated to be an important mediator of resistance to chemotherapy and disease relapse. We hypothesized that inhibition of the CXCR4/CXCL12 axis by the small molecule inhibitor, plerixafor, would disrupt the interaction of leukemic blasts with the environment and increase the sensitivity of AML blasts to chemotherapy. In this phase 1/2 study, 52 patients with relapsed or refractory AML were treated with plerixafor in combination with mitoxantrone, etoposide, and cytarabine. In phase 1, plerixafor was escalated to a maximum of 0.24 mg/kg/d without any dose-limiting toxicities. In phase 2, 46 patients were treated with plerixafor 0.24 mg/kg/d in combination with chemotherapy with an overall complete remission and complete remission with incomplete blood count recovery rate (CR + CRi) of 46%. Correlative studies demonstrated a 2-fold mobilization in leukemic blasts into the peripheral circulation. No evidence of symptomatic hyperleukocytosis or delayed count recovery was observed with the addition of plerixafor. We conclude that the addition of plerixafor to cytotoxic chemotherapy is feasible in AML, and results in encouraging rates of remission with correlative studies demonstrating in vivo evidence of disruption of the CXCR4/CXCL12 axis. This study was registered at www.clinicaltrials.gov, no. NCT00512252. PMID:22308295

Radiofrequency ablation (RFA) combined with chemotherapy has a certain short-term therapeutic effect for the treatment of advanced non-small cell lung cancer (NSCLC), but whether it can improve the long-term survival rate of patients is still controversy. This study retrospectively analyzed the difference of long-term efficacy between RFA combined with chemotherapy and chemotherapy alone in the treatment of patients with advanced NSCLC. A total of 77 patients with stage IIIb and stage IV NSCLC who underwent radiofrequency ablation and chemotherapy in the Department of Thoracic Surgery, Xuanwu Hospital, Capital University of Medical Sciences from September 2009 to December 2015 were enrolled as the treatment group. Chemotherapy with no radiofrequency ablation was performed in 56 patients with stage IIIb and stage IV NSCLC as the control group. Two groups of patients were followed up by telephone about their living conditions. "Survival" package of R software version 3.4.1 was used for statistical analysis. Two sets of data baseline levels were tested by chi-square test. The bias was processed by Cox regression model and the survival curve was plotted using covariate mean substitution method. The first-year survival rate of the treatment group was 70.74%, the two-year survival rate was 39.31% and the median survival time was 22.1 months. The one-year survival rate was 54.54% in the control group, the two-year survival rate was 19.49%, the median survival for 18.1 months. The long-term survival rate of the treatment group was better than that of the control group (P<0.05, OR=0.571). Radiofrequency ablation of lung cancer combined with chemotherapy can significantly improve the 2-year survival rate of patients with stage IIIb and stage IV NSCLC.

We analyzed the treatment responses, toxicities, and survival outcomes of patients with relapsed or refractory multiple myeloma who received daily thalidomide, cyclophosphamide, and dexamethasone (CTD) or daily thalidomide, melphalan, and prednisolone (MTP) at 17 medical centers in Korea. Three-hundred and seventy-six patients were enrolled. The combined chemotherapy of thalidomide, corticosteroid, and an alkylating agent (TAS) was second-line chemotherapy in 142 (37.8%) patients, and third-line chemotherapy in 135 (35.9%) patients. The response rate overall was 69.4%. Patients who were not treated with bortezomib and lenalidomide before TAS showed a higher response rate compared to those who were exposed to these agents. The estimated median progression-free survival and overall survival times were 10.4 months and 28.0 months, respectively. The adverse events during TAS were generally tolerable, but 39 (10.4%) patients experienced severe infectious complications. There were no differences in terms of efficacy between CTD and MTP, but infectious complications were more common in CTD group. TAS is an effective treatment regimen which induces a high response rate in relapsed or refractory multiple myeloma patients. Due to the high incidence of grade 3 or 4 infection, proper management of infection is necessary during the TAS treatment, especially the CTD. © 2016 The Authors.

Nodular lymphocyte predominant Hodgkin lymphoma represents a distinct entity from classical Hodgkin lymphoma. We conducted a retrospective study to investigate the management of patients with nodular lymphocyte predominant Hodgkin lymphoma. Clinical characteristics, treatment and outcome of adult patients with nodular lymphocyte predominant Hodgkin lymphoma were collected in Lymphoma Study Association centers. Progression-free survival (PFS) and overall survival (OS) were analyzed, and the competing risks formulation of a Cox regression model was used to control the effect of risk factors on relapse or death as competing events. Among 314 evaluable patients, 82.5% had early stage nodular lymphocyte predominant Hodgkin lymphoma. Initial management consisted in watchful waiting (36.3%), radiotherapy (20.1%), rituximab (8.9%), chemotherapy or immuno-chemotherapy (21.7%), combined modality treatment (12.7%), or radiotherapy plus rituximab (0.3%). With a median follow-up of 55.8 months, the 10-year PFS and OS estimates were 44.2% and 94.9%, respectively. The 4-year PFS estimates were 79.6% after radiotherapy, 77.0% after rituximab alone, 78.8% after chemotherapy or immuno-chemotherapy, and 93.9% after combined modality treatment. For the whole population, early treatment with chemotherapy or radiotherapy, but not rituximab alone (Hazard ratio 0.695 [0.320–1.512], P=0.3593) significantly reduced the risk of progression compared to watchful waiting (HR 0.388 [0.234–0.643], P=0.0002). Early treatment appears more beneficial compared to watchful waiting in terms of progression-free survival, but has no impact on overall survival. Radiotherapy in selected early stage nodular lymphocyte predominant Hodgkin lymphoma, and combined modality treatment, chemotherapy or immuno-chemotherapy for other patients, are the main options to treat adult patients with a curative intent.

To evaluate the efficacy and side effects of combined Chinese drugs and chemotherapy in treating advanced non-small cell lung cancer (NSCLC). Sixty-three patients with stage III B and IV NSCLC hospitalized from October 2001 to October 2008 were enrolled and assigned to two groups using a randomizing digital table, with 33 patients in the treatment group and 30 in the control group. They were all treated with the Navelbine and Cisplatin (NP) chemotherapy, but to the treatment group the Chinese drugs Shengmai Injection () by intravenous dripping and Gujin Granule () by oral intake were given additionally. The main observation indexes were response rate (RR), median survival time, 1-year survival rate and median time to progression (TTP); secondary observation indexes were side effects and cycles of chemotherapy. Altogether, 61 patients (33 from the treatment group and 28 from the control group) completed the observation and were assessable. RR was 48.5% (16/33) in the treatment group and 32.2% (9/28) in the control group, and the median survival time were 13 months and 9 months, respectively; the difference between the two groups was significant (P=0.0373 and P=0.014 respectively). However, the differences between groups were insignificant in terms of 1-year survival rate [51.5% (17/33) vs 46.4% (13/28), P=0.4042], median TTP (5.95 months vs 4.64 months, P=0.3242), grade III or IV bone marrow inhibition occurrence rate [33.3% (11/33) vs 39.3% (11/28), P=0.3500], and mean cycles of chemotherapy applied (2.94+/-0.94 cycles vs 2.75+/-0.75 cycles, P=0.4100). Combined Chinese drugs and chemotherapy can enhance the short-term therapeutic efficacy in the treatment of NSCLC and prolong patients' median survival time, but show no evident impact on TTP.

Despite the scientific evidence undoubtedly influencing current guidelines on the management of metastatic Breast cancer (mBC), marketing research data suggests this may not be reflected in EU prescribing behavior. Specifically we would like to understand the use of combination chemotherapy vs monotherapy in mBC patients. This study is based on IMS Oncology Analyzer™, a web-based physician panel survey set-up by IMS Health, a global company which specializes in health care information including market research data. Analysis was carried out on prescribing behavior reflected in marketing research data from IMS source (from MAT Q42013 till MAT Q32014) and comparing the data with the current guidelines recommendation in mBC (ESO-ESMO 2nd international consensus guidelines). In 1st line mBC around 17% of patients are treated with combination chemotherapy drugs. The combination chemotherapy are essentially anthracycline based than taxane based. In 2nd + line mBC a higher proportion of monotherapy (chemotherapy+/-biologics) is being used. Despite the recommendation provided by current ESMO guidelines on mBC treatments, indicating the sequential use of single cytotoxic agents is a considerable alternative to standard multidrug chemotherapy regimens, marketing research data suggests this may not be reflected in EU prescribing behavior.

Objective: To investigate the clinical value of two-dimensional speckle tracking echocardiography(2D-STE) combined with high-sensitive cardiac troponin T (hs-cTnT) in early detection of the cardiotoxicity induced by chemotherapy drug. Methods: Seventy-five non-Hodgkin's lymphoma patients who received the CHOP regimen were recruited in this study. Conventional echocardiography and 2D-STE were performed on these patients before chemotherapy, the second day after the third course of chemotherapy (during chemotherapy) and the second day after the last course of chemotherapy (after chemotherapy). The parameters included left ventricular ejection fraction (LVEF), global longitudinal strain (LS), global circumferential strain (CS) and global radial strain (RS). The serum hs-cTNT levels were tested simultaneously. Results: Three cycles of CHOP were completed in 30 patients and 6-8 cycles of CHOP were completed in 45 patients. The LVEF of 75 patients before, during and after chemotherapy was (63.8±2.6)%, (63.8±2.8)% and (64.0±3.3)%, respectively, without significant difference ( P =0.91). However, the LS of 75 patients before, during and after chemotherapy was (-18.5±1.7)%, (-16.5±1.9)% and (-16.0±1.6)%, respectively. The CS was (-20.9±2.9)%, (-19.3±3.5)% and (-19.2±3.2)%, respectively. The RS was (39.2±6.4)%, (35.3±5.2)% and (35.0±6.2)%, respectively. The hs-cTnT was (0.001 0±0.002 0)ng/ml, (0.006 3±0.008 9)ng/ml and (0.007 3±0.003 8)ng/ml, respectively. The LS, CS and RS were significantly decreased while hs-cTnT was significantly increased during chemotherapy when compared to those before chemotherapy (all of P <0.01). Alternatively, the LS, CS, RS and hs-cTnT after chemotherapy were marginally different from those during chemotherapy (all of P >0.05). Moreover, T(LS-SD), T(CS-SD) and T(RS-SD) showed no significant difference before, during and after chemotherapy (all of P >0.05). The reduction of LS was positively associated with the enhancement of hs-cTnT after chemotherapy ( r =0.60, P <0.01). Conclusion: 2D-STE combined with hs-cTnT can effectively and precisely detect the occult cardiotoxicity induced by anthracycline.

The standard treatment for ovarian cancer is chemotherapy with 2 drugs (taxanes and platinum drugs). However, the traditional combination of the 2 drugs has many adverse effects (AEs) and the cancer cells will quickly become resistant to the drugs. Apatinib is a small-molecule antiangiogenic agent which has shown promising therapeutic effects against diverse tumor types, but it still remains unknown whether apatinib has an antitumor effect in patients with ovarian cancer. Herein, we present a successfully treated case of ovarian cancer using chemotherapy and apatinib, in order to demonstrate the effectiveness of this new combined regimen in ovarian cancer. A 51-year-old Chinese woman presented with ovarian cancer >4.5 years. The disease and the cancer antigen 125 (CA-125) had been controlled well by surgical treatment and following chemotherapy. However, the drugs could not control the disease anymore as the CA-125 level was significantly increasing. Ovarian cancer. The patient was treated with apatinib combined with epirubicin. Apatinib was administered orally, at an initial daily dose of 500 mg, and was then reduced to 250 mg qd after the appearance of intolerable hand-foot syndrome (HFS) and oral ulcer. Then, the oral ulcer disappeared and the HFS was controlled by dose adjustment, oral vitamin B6, and hand cream application. The CA-125 reverted to the normal value after treatment with the new regimen. Magnetic resonance imaging showed that the original tumor lesions had disappeared. Apatinib monotherapy as maintenance therapy was then used to successfully control the cancer with a complete response. Our study is the first, to our knowledge, to report the therapeutic effects of apatinib and epirubicin on ovarian cancer. Apatinib combined with chemotherapy and apatinib monotherapy as maintenance therapy could be a new therapeutic strategy for ovarian cancer, especially adenocarcinomas.

To explore the feasibility and activity of a histology-based induction combination chemotherapy for elderly patients with clinical stage III non-small cell lung cancer (NSCLC). Patients aged ≥70 years with stage IIIA and IIIB lung squamous cell carcinoma (SCC) or adenocarcinoma were treated with three cycles of carboplatin and gemcitabine or pemetrexed, respectively, followed by definitive radiotherapy or surgery. The primary endpoint was the overall response rate (ORR) following induction. Twenty-seven patients, with a median age of 74 years (range=70-80 years) were treated for adenocarcinoma in 14 (52%) and SCC in 13 (48%), clinical stage IIIA in eight (30%) and IIIB in 19 (70%). Grade 3 or 4 toxicity was reported for five patients (18.5%). The ORR was 46% in 12 (partial responses) out of 26 assessable patients. Histology-based induction combination chemotherapy is active and feasible in elderly patients with stage III NSCLC. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

Rationale for combining immunotherapy with chemotherapy.

PubMed

Dalgleish, Angus G

2015-01-01

Immunotherapy has usually been considered as an alternative to more traditional modalities. Moreover, it has previously been felt that chemotherapy is inherently immunosuppressive and not suitable for combining with immunotherapy. In this review, the concept of combining different modalities that result in cell death, such as radiotherapy and chemotherapy, with immunotherapy is explored. Tumors actively cause immune suppression which can be reversed by their removal but when this is not possible, enhancing the immune response with nonspecific immune stimulation can enhance the response to other modalities, such as radiotherapy and chemotherapy. Additionally, several chemotherapy agents at low doses selectively inhibit regulatory and suppressor cells.

After progression to a standard first-line platinum and gemcitabine combination (GP), there is no established second-line therapy for patients with advanced biliary tract cancers (aBTC). Indeed, literature data suggest limited activity of most second-line agents evaluated so far. We collected a large retrospective series of aBTC patients treated with second-line chemotherapy after progression to a first-line GP regimen at different Italian institutions. We then pooled the data with those reported in previous studies, which were identified with a Medline search and the on-line abstract datasets of major international oncology meetings. A total of 174 patients were included in the multicenter survey: response rate (RR) with second-line chemotherapy was low (3.4 %), with median PFS and OS of 3.0 months and 6.6 months, respectively. At multivariate analysis, preserved performance status, low CA19.9 levels and absence of distant metastases were favorable prognostic factors. Data from other five presented or published series were identified, for a total of 499 patients included in the pooled analysis. The results confirmed marginal activity of second-line chemotherapy (RR: 10.2 %), with limited efficacy in unselected patient populations (median PFS: 3.1 months; median OS: 6.3 months). The current analysis highlights the limited value of second-line chemotherapy after a first-line GP combination in aBTC. While waiting for effective biologic agents in this setting, ongoing randomized trials will identify the optimal second-line chemotherapy regimen and validate prognostic factors for individual patient management.

The objective of this analysis was to evaluate the efficacy and treatment outcome of CHOP and CHOP combined with nitrosourea chemotherapy in natural killer (NK)/T-cell lymphoma of the nasal cavity. Sixty-three patients with NK/T-cell lymphoma of the nasal cavity were treated with CHOP or CHOP combined with oral nitrosourea chemotherapy between January 1997 and June 2005. By the Ann Arbor Lymphoma Staging Classification, 57 patients (90%) had Stage IE or IIE disease and six patients (10%) had Stage III or IV disease. All patients with Stage IE or IIE disease were intended to be treated curatively with combined chemoradiation; and patients who had Stage III or IV disease were treated with chemotherapy alone with curative intention. Chemotherapy consisted of: (1) up to six cycles of the standard CHOP based regimen, or (2) up to six cycles of the standard CHOP based regimen with oral Semustine dosed at 120 mg (or Lomustine dosed at 100mg) on day 1 of each chemotherapy cycle. External beam radiation therapy was delivered by daily conventional fractionation by Co-60 or 6MVx linear accelerator for patients with Stage IE or IIE disease. The radiation dose to the tumor bed was between 36 and 50 Gy with a median dose of 45 Gy. Fifty-three patients received chemotherapy prior to radiation, and four patients were treated with involved field radiation before chemotherapy. The median follow up for all 44 surviving patients was 31 months (range: 6-104 months). The 2-year progression-free survival (PFS) and overall survival (OS) rates were 60% and 70%, respectively. The PFS and OS of patients who were treated with or without oral nitrosourea in addition to CHOP were 73% vs. 44% (P=0.035) and 75% vs. 64% (P=0.276), respectively. Nine patients with Stage IE or IIE diseases developed disease progression during their planned treatment and died within 10 months after the initiation of treatment; Six patients who achieved complete response (CR) after planned chemoradiation developed systemic recurrence and died at 13-48 months despite salvage treatment; one patient died of Hemophagocytic Syndrome during radiotherapy after achieving CR from chemotherapy. Three patients with Stage III or IV disease died during chemotherapy or during salvage treatment at 2, 4, and 19 months, respectively. Among the 59 patients who received chemotherapy as their initial treatment, 29, 6, 12, and 12 patients had complete response (CR), partial response (PR), stable disease (SD), and progressive disease (PD) respectively after chemotherapy. The 2-year overall survival rates for these four groups of patients were 100%, 75%, 60%, and 17%, respectively (P<0.0001). Multivariate analysis revealed that International Prognostic Index (IPI) for Lymphoma, perforation of nasal septum as a presenting symptom, "B" symptoms, ECOG performance, as well as response after chemotherapy, were significant independent prognostic factors for this group of patients. The extent of response after induction chemotherapy is significantly related to the treatment outcome of patients with nasal NK/T-cell lymphoma. CHOP based chemotherapy combined with oral nitrosourea followed by involved field radiotherapy may provide improved treatment results compared to conventional CHOP chemotherapy and radiation. This strategy needs to be optimized and tested in a prospective trial for its efficacy.

Lymph node-positive bladder cancer is a systemic disease in the majority of patients. Adjuvant chemotherapy given shortly after surgery, when tumor burden is low, seems reasonable, yet there is no proof that it improves survival. In this retrospective study, we compare the outcomes of patients with microscopic lymph node positive bladder cancer (pN1 or pN2) treated with radical cystectomy followed by adjuvant chemotherapy and those who declined chemotherapy. Sixty-seven patients with lymph node positive bladder cancer (26 pN1 and 41 pN2) who underwent radical cystectomy between April 1995 and April 2005 were reviewed. Combined adjuvant chemotherapy (gemcitabine and cisplatin in most patients) was given to 35 patients (52%), but declined by 32 (48%). The two groups were similar in performance status, postoperative complication rate, and N stage but deferring patients were on average 5 years older and had a more advanced T stage. Study primary endpoint was overall survival (OS). Adjuvant chemotherapy was well tolerated and 28/35 patients (80%) completed all 4 cycles. Median OS of patients given adjuvant chemotherapy was 48 months compared with 8 months for declining patients (hazard ratio 0.13, 95% CI 0.04-0.4, P < 0.0001). Multivariate age adjusted analysis showed that adjuvant chemotherapy was an independent factor affecting OS (hazard ratio 0.2, P < 0.0001). This study supports the use of adjuvant chemotherapy after radical cystectomy in patients with node positive bladder cancer. Study design and patient imbalances make it impossible to draw definitive conclusions.

To begin with, in this paper, single immunotherapy, single chemotherapy, and mixed treatment are discussed, and sufficient conditions under which tumor cells will be eliminated ultimately are obtained. We analyze the impacts of the least effective concentration and the half-life of the drug on therapeutic results and then find that increasing the least effective concentration or extending the half-life of the drug can achieve better therapeutic effects. In addition, since most types of tumors are resistant to common chemotherapy drugs, we consider the impact of drug resistance on therapeutic results and propose a new mathematical model to explain the cause of the chemotherapeutic failure using single drug. Based on this, in the end, we explore the therapeutic effects of two-drug combination chemotherapy, as well as mixed immunotherapy with combination chemotherapy. Numerical simulations indicate that combination chemotherapy is very effective in controlling tumor growth. In comparison, mixed immunotherapy with combination chemotherapy can achieve a better treatment effect. PMID:26997972

Lepromatous leprosy treated with combined chemotherapy and immunotherapy (injection BCG): three case reports.

PubMed

Lakshmi, Chembolli; Srinivas, Chakravarthi Rangachari

2014-01-01

Lepromatous leprosy is associated with suppressed cell-mediated immunity (CMI). This results in failure of the body to mount an efficient immune response and may render chemotherapy ineffective. The lack of sufficient response may mimic drug resistance. Three case reports in which the immunity was stimulated by administering Injection BCG are presented. All three patients were initially anergic and showed no reaction at the Mantoux testing site, showing an inability to mount type IV hypersensitivity and characterized by live bacilli in smears. Following 1-4 doses of Injection BCG, all three showed dead bacilli in smears. The first case, a 61-year-old man with lepromatous leprosy who continued to show live bacilli in smears after prolonged chemotherapy, was administered a total of four BCG injections, following which he achieved clearance. The second, a 40-year-old man with borderline lepromatous leprosy and severe type 2 reactions, achieved bacterial clearance and control of severe reactions following a single injection. The third, a 67-year-old man with histoid leprosy, achieved effective bacterial killing with a single dose of Injection BCG. All three patients achieved good results when chemotherapy was combined with Injection BCG. Following Injection BCG, all three showed a reaction at the Mantoux testing site. Suppressed CMI may be responsible for the lack of response in recalcitrant cases of lepromatous leprosy. These case reports would lead to the trend in combination therapy (immunotherapy combined with chemotherapy) for such cases, and help lower the tendency for inappropriate diagnosis of drug-resistant leprosy. © 2013 The International Society of Dermatology.

This study evaluated a multifunctional micelle simultaneously loaded with doxorubicin (Dox) and labeled with radionuclide rhenium-188 (188Re) as a combined radiotherapy and chemotherapy treatment for hepatocellular carcinoma. We investigated the single photon emission computed tomography, biodistribution, antitumor efficacy, and pathology of 188Re-Dox micelles in a murine orthotopic luciferase-transfected BNL tumor cells hepatocellular carcinoma model. The single photon emission computed tomography and computed tomography images showed high radioactivity in the liver and tumor, which was in agreement with the biodistribution measured by γ-counting. In vivo bioluminescence images showed the smallest size tumor (P<0.05) in mice treated with the combined micelles throughout the experimental period. In addition, the combined 188Re-Dox micelles group had significantly longer survival compared with the control, 188ReO4 alone (P<0.005), and Dox micelles alone (P<0.01) groups. Pathohistological analysis revealed that tumors treated with 188Re-Dox micelles had more necrotic features and decreased cell proliferation. Therefore, 188Re-Dox micelles may enable combined radiotherapy and chemotherapy to maximize the effectiveness of treatment for hepatocellular carcinoma. PMID:26719687

To assess the feasibility of metronomic chemotherapy in the palliative care setting. To study the toxicity profile and efficacy of metronomic chemotherapy for palliation in oral cavity cancers. Retrospective analysis of prospectively collected data. Subjects receiving metronomic chemotherapy from August 2010 to January 2011 for palliation in oral cancers subjected to certain criteria were included. Metronomic chemotherapy offered was a combination of twice daily celecoxib 200 mg and weekly methotrexate 15 mg/m 2 .The chemotherapy was continued till disease progression, intolerable side effects or patients' desire to stop. The toxicity profile was reported in accordance with common terminology criteria for adverse events (CTCAE) version 4.02. The efficacy was noted in terms of symptom control, response rates, progression free survival (PFS) and overall survival (OS). SPSS version 16 has been utilized. Descriptive analysis has been presented. The Kaplan-Meier survival analysis was performed for estimation of the PFS and OS. Eighteen patients with a median age of 50.5 years, 13 males and 5 females, participated in the study. Five patients had received no previous treatment while the rest had some form of previous treatment. ECOG performance status was 1 in 14 patients and 2 in 4 patients. Grade 3-4 mucositis was seen in one patient. Clinical benefit rate was 66.67%. The estimated median PFS and median OS were 5.2 months and not reached respectively. Use of metronomic chemotherapy seems promising and well tolerated in this setting. Large trials are warranted to confirm these results.

Evidence has suggested survival benefits of maintenance for advanced NSCLC patients not progressing after first-line chemotherapy. Additionally, particular first-line targeted therapies have shown survival improvements in selected populations. Optimal first-line and maintenance therapies remain unclear. Here, currently available evidence was synthesized to elucidate optimal first-line and maintenance therapy within patient groups. Literature was searched for randomized trials evaluating first-line and maintenance regimens in advanced NSCLC patients. Bayesian network meta-analysis was performed within molecularly and clinically selected groups. The primary outcome was combined clinically meaningful OS and PFS benefits. A total of 87 records on 56 trials evaluating first-line treatments with maintenance were included. Results showed combined clinically meaningful OS and PFS benefits with particular first-line with maintenance treatments, (1) first-line intercalated chemotherapy+erlotinib, maintenance erlotinib in patients with EGFR mutations, (2) first-line afatinib, maintenance afatinib in patients with EGFR deletion 19, (3) first-line chemotherapy + bevacizumab, maintenance bevacizumab in EGFR wild-type patients, (4) chemotherapy+conatumumab, maintenance conatumumab in patients with squamous histology, (5) chemotherapy+cetuximab, maintenance cetuximab or chemotherapy + necitumumab, maintenance necitumumab in EGFR FISH-positive patients with squamous histology, and (6) first-line chemotherapy+bevacizumab, maintenance bevacizumab or first-line sequential chemotherapy+gefitinib, maintenance gefitinib in patients clinically enriched for EGFR mutations with nonsquamous histology. No treatment showed combined clinically meaningful OS and PFS benefits in patients with EGFR L858R or nonsquamous histology. Particular first-line with maintenance treatments show meaningful OS and PFS benefits in patients selected by EGFR mutation or histology. Further research is needed to achieve effective therapy for patients with EGFR mutation L858R or nonsquamous histology. © 2017 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

Our purpose was to evaluate the survival of patients with pleural and intraperitoneal malignant mesothelioma and, particularly, to estimate the efficacy of chemotherapy as well as radiotherapy and surgery. A review of the literature with respect to these parameters is included. Thirty-five patients with malignant mesothelioma (28 with pleural and 7 with intraperitoneal) were enrolled. Twenty-eight patients underwent chemotherapy, 7/35 radiation and 9/35 surgery (2 with pleural and 7 with abdominal disease). Combination chemotherapy included cisplatin-gemcitabine, cisplatin (or carboplatin) with premetrexed and doxorubicin-cyclophosphamide. In 2/28 patients with pleural mesothelioma the tumor was excised and in 7 with intraperitoneal disease, surgical therapy was palliative and there was survival prolongation. Radiotherapy was only palliative. Chemotherapy produced a very low response: 2/28 (7.14%) patients achieved a partial response. The median survival was 17 months, 4-year survival, 24.4% and 5-year survival, 12.12%. No serious toxicity was observed. Malignant mesothelioma of the pleura and intraperitoneum is a slow-growing disease which is indicated by the long survival, despite the failure of chemotherapy, radiation therapy and surgery.

The SDF-1 receptor CXCR4 has been associated with early metastasis and poorer prognosis in breast cancers, especially the most aggressive triple-negative subtype. In line with previous reports, we found that tumoral CXCR4 expression in patients with locally advanced breast cancer was associated with increased metastases and rapid tumor progression. Moreover, high CXCR4 expression identified a group of bone marrow-disseminated tumor cells (DTC)-negative patients at high risk for metastasis and death. The protein epitope mimetic (PEM) POL5551, a novel CXCR4 antagonist, inhibited binding of SDF-1 to CXCR4, had no direct effects on tumor cell viability, but reduced migration of breast cancer cells in vitro. In two orthotopic models of triple-negative breast cancer, POL5551 had little inhibitory effect on primary tumor growth, but significantly reduced distant metastasis. When combined with eribulin, a chemotherapeutic microtubule inhibitor, POL5551 additively reduced metastasis and prolonged survival in mice after resection of the primary tumor compared with single-agent eribulin. Hypothesizing that POL5551 may mobilize tumor cells from their microenvironment and sensitize them to chemotherapy, we used a "chemotherapy framing" dosing strategy. When administered shortly before and after eribulin treatment, three doses of POL5551 with eribulin reduced bone and liver tumor burden more effectively than chemotherapy alone. These data suggest that sequenced administration of CXCR4 antagonists with cytotoxic chemotherapy synergize to reduce distant metastases. ©2015 American Association for Cancer Research.

Allogeneic hematopoietic stem cell transplantation (SCT) contributes to improved outcome in childhood acute leukemia (AL). However, therapeutic options are poorly defined in the case of post-transplantation relapse. We aimed to compare treatment strategies in 334 consecutive children with acute leukemia relapse or progression after SCT in a recent 10-year period. Data could be analyzed in 288 patients (157 ALL, 123 AML and 8 biphenotypic AL) with a median age of 8.16 years at transplantation. The median delay from first SCT to relapse or progression was 182 days. The treatment consisted of chemotherapy alone (n=108), chemotherapy followed by second SCT (n=70), supportive/palliative care (n=67), combination of chemotherapy and donor lymphocyte infusion (DLI; n=30), or isolated reinfusion of donor lymphocytes (DLI; n=13). The median OS duration after relapse was 164 days and differed according to therapy: DLI after chemotherapy=385 days, second allograft=391 days, chemotherapy=174 days, DLI alone=140 days, palliative care=43 days. A second SCT or a combination of chemotherapy and DLI yielded similar outcome (hazard ratio (HR)=0.85, P=0.53) unlike chemotherapy alone (HR=1.43 P=0.04), palliative care (HR=4.24, P<0.0001) or isolated DLI (HR=1,94, P<0.04). Despite limitations in this retrospective setting, strategies including immunointervention appear superior to other approaches, mostly in AML.

To explore the clinical effect and toxicity of (cisplatin, etoposide, ifosfamide & dexamethasone) DECP combination chemotherapy in the treatment of relapsing and refractory multiple myeloma (MM) with extramedullary plasmacytomas. A total of 20 relapsed and refractory MM patients with extramedullary plasmacytomas treated with DECP regimen from May 2005 to May 2013 were analyzed retrospectively. DECP protocols included cisplatin 20 mg/m(2), Day 1-3; etoposide 100 mg/d,Day 1-3; ifosfamide 500 mg·m(-2)·d(-1), Day 1-4; dexamethasone 20 mg/d, Day 1-4. Efficacy was evaluated after 2 therapeutic cycles. After 2 therapeutic cycles, the objective response rate (ORR) was 55% (11/20). After 3 therapeutic cycles, the ORR was 7/12.Seven patients completed 4 cycles with an ORR of 4/7. Two patients had finished 6 cycles and continued to maintain partial remission. The most common adverse events included gastrointestinal reaction and myelosuppression. The median follow-up time was 30 (12-80) months. The median time of overall survival (OS) was 30 (9-121) months. The 1-year OS was 73%, 2-year OS 28% and 3-year OS 21%. The DECP chemotherapy is both effective and safe in the treatment of relapsed and refractory MM patients with extramedullary plasmacytomas.

A case of bilateral testicular seminomas with abdominal huge metastatic tumors is presented. The patient is a 23-year-old male. An abdominal huge mass was found incidentally by a physician. CT scan and ultrasonography revealed the presence of the tumor in the left retroperitoneal space and biopsy specimen of the abdominal tumor was diagnosed as seminoma. On March 7, 1985, he was referred to our clinic. Bilateral testicular tumors were detected on palpation and ultrasonography. Bilateral orchiectomy was performed. Histological diagnosis was pure seminoma. After four sessions of VAB-6 combined chemotherapy, the abdominal tumor, 14.1 x 12.3 cm in size, decreased to 5.7 x 4.4 cm ( a regression rate of 85.5%). Retroperitoneal lymph-node dissection was undertaken, but the abdominal tumor could not be resected completely. Histological examination of the resected tumor revealed complete necrosis of the tumor tissue. After the operation, one session of the chemotherapy and irradiation were added. A total of 109 cases of bilateral testicular germ cell tumors in Japan was reviewed.

The interplay between the immune system and chemotherapy: emerging methods for optimizing therapy.

Preclinical studies have revealed an unexpected ability of the immune system to contribute to the success of chemotherapy and radiotherapy. Anticancer therapies can trigger immune system activation by promoting the release of danger signals from dying tumor cells and/or the elimination of immunosuppressive cells. We have, however, recently discovered that some chemotherapies, such as 5-fluorouracil and gemcitabine, exert conflicting effects on anticancer immune responses. Although 5-fluorouracil and Gem selectively eliminated myeloid-derived suppressive cells in tumor-bearing rodents, these chemotherapies promoted the release of IL-1β and the development of pro-angiogenic IL-17-producing CD4 T cells. The ambivalent effects of chemotherapy on immune responses should thus be carefully considered to design effective combination therapies based on chemotherapy and immune modulators. Herein, we discuss how the initial findings underscoring the key role of the immune system in mediating the antitumor efficacy of anticancer agents could begin to translate into effective therapies in humans.

The time for the neutrophil count to recover after subcutaneous injection of filgrastim BS1 or lenograstim was studied in patients suffering from neutropenia following preoperative combined chemotherapy using docetaxel, nedaplatin, or cisplatin (in divided doses for 5 days)and 5-fluorouracil for oral cancer. 1. There was no significant difference in the minimum leukocyte and neutrophil counts after chemotherapy. 2. There was no significant difference in the maximum leukocyte and neutrophil counts after chemotherapy. 3. Time for leukocytes to recover from their minimum count(>4,000/mm3)or for neutrophils to recover from their minimum count(>2,000/mm3)and the number of days on which treatment was administered tended to be shorter in the filgrastim BS1 group. Thus, it was concluded that filgrastim BS1 is just as effective as other prior G-CSF agents in treating patients suffering from neutropenia following chemotherapy(TPF therapy).

Palliative chemotherapy is the main treatment for advanced biliary tract cancer (BTC). However, there is a lack of established second-line chemotherapy to treat disease progression after first-line chemotherapy. We examined combination therapy with capecitabine and cisplatin for advanced BTC as a second-line regimen. We analyzed the medical records of 40 patients diagnosed with BTC who received palliative second-line chemotherapy with capecitabine and cisplatin. The median overall survival from the start of second-line chemotherapy was 6.3 months. The median overall survival from diagnosis was 17.9 months. The median progression-free survival during second-line chemotherapy was 2.3 months. Nine (30%) patients experienced adverse events of grade ≥3. Eastern Cooperative Oncology Group performance score was an independent predictor of adverse events. Combination therapy with capecitabine and cisplatin may be an option for second-line chemotherapy in some of patients with advanced BTC. © 2017 S. Karger AG, Basel.

T-cell stimulators such as anti-CTLA-4 antibodies enhance immunologic responses to chemotherapy-resistant solid tumors, such as melanoma, advanced breast cancer, ovarian cancer and pancreatic cancer. The efficacy of these new immunotherapy agents can in theory be enhanced substantially by therapies that stimulate new immunologic (T-cell) responses against the tumor. Laser immunotherapy (LIT) with imiquimod and InCVAX are techniques that produce useful responses in patients with advanced melanoma, the prototypical chemotherapy resistant solid tumor. The mechanism of action of these therapies is thought to be immunological, including the development of new T-cell responses. We have therefore been combining LIT using imiquimod and InCVAX treatment with the new T-cell stimulators (ipilimumab) in cases of stage IV melanoma. While still anecdotal, the use of novel combinations of immunologic therapies should provide much improved responses for chemotherapy-resistant solid tumors (such as melanoma) than was previously possible. Newer T-cell stimulating drugs such as the anti-PD-1 antibodies and anti-PD-L1 antibodies will make this general approach to treating chemoresistant advanced tumors even more effective in the future.

Colorectal adenocarcinoma ranks second as a cause of death due to cancer in the Western world. Already at the time of the primary tumor, 15-25% of the patients present with liver metastases while another 20% will develop metastasis following treatment of the colorectal primary. Without any treatment the median survival after the detection of metastases is approximately 9 months, depending on the extent of the disease at the time of diagnosis. Clinical trials with the "FOLFOX and FOLFIRI families" of drugs, designed for the treatment of metastatic colorectal cancer, their results and the costs of each therapy are examined. For each drug, the cost/mg, the cost/mg/m2 and the cost/therapy (according to its duration) are evaluated according to the prices reported in the Italian Directory of Medicines and Manufacturers, 63rd Edition, November 2003.

Forty patients with primary malignant brain tumor were treated by combination chemotherapy after prior treatment with surgery and radiotherapy. The chemotherapy schedule consisted of PCV: procarbazine per os, 100 mg/m2, during 14 consecutive days; CCNU, per os, 80 mg/m2 on day 1 and vincristine, intravenously, 1.4 mg/m2 on days 1 and 14. This protocol was planned to be repeated every 45 days for 6 courses. Median 5 courses (range, 2-6) of chemotherapy was administered to patients. The median relapse free (RFS) and overall survival (OS) rates were found to be 28 and 79+ months, respectively. According to univariate analysis, performance status (PS) of patients was an important prognostic factor on RFS and OS where extent of surgery was an additional significant determinant of OS. Multivariate analysis of pretreatment factors revealed the influence of sex, type of histopathology and PS on RFS and that of PS on OS rates (P < 0.05). The toxicity of this regimen was mild to moderate. The major toxicity noted was myelosuppression. Severe (grade III-IV) neutropenia and thrombocytopenia has been observed in 13 (7%) and 6 courses (3.5%), respectively. In general, PCV is well tolerated and the median RFS and OS times elucidated are comparable with particular trials utilizing combination chemotherapy and longer than using radiotherapy alone.

Background To determine the 5-year recurrence-free survival in patients with high-risk prostate cancer after neoadjuvant combination chemotherapy followed by surgery. Secondary endpoints included safety, pathologic effects of chemotherapy and predictors of disease recurrence. Patients and Methods Fifty seven patients were enrolled in a Phase I/II study of weekly docetaxel 35 mg/m2 and escalating mitoxantrone to 4 mg/m2 prior to prostatectomy. Patients were treated with 16 weeks of chemotherapy administered weekly on a 3 of every 4 week schedule. A tissue micro-array, constructed from the prostatectomy specimens served to facilitate the exploratory evaluation of biomarkers. The primary end point was relapse-free survival. Relapse was defined as a confirmed serum prostate-specific antigen (PSA) > 0.4 ng/ml. Results Of the 57 patients, 54 received 4 cycles of docetaxel and mitoxantrone prior to radical prostatectomy. Grade 4 toxicities were limited to leucopenia, neutropenia and hyperglycemia. Serum testosterone levels remained stable after chemotherapy. Negative surgical margins were attained in 67% of cases. Lymph node involvement was detected in 18.5% of cases. With a median follow-up of 63 months, 27 of 57 (47.4%) patients recurred. The Kaplan-Meier relapse-free survival at 2 years was 65.5% (95%CI 53.0% to 78.0%) and 49.8% at 5 years (95%CI 35.5% to 64.1%). Pretreatment serum PSA, lymph node involvement, and post-chemotherapy tissue VEGF expression were independent predictors of early relapse. Conclusions Preoperative chemotherapy with docetaxel and mitoxantrone is feasible. Approximately half of the high risk patients remain relapse free at 5 years and clinical and molecular predictors of early relapse were identified. PMID:20143429

Optimal chemotherapy treatment for women with recurrent ovarian cancer

Question What is the optimal chemotherapy treatment for women with recurrent ovarian cancer who have previously received platinum-based chemotherapy? Perspectives Currently, standard primary therapy for advanced disease involves a combination of maximal cytoreductive surgery and chemotherapy with carboplatin plus paclitaxel or with carboplatin alone. Despite initial high response rates, a large proportion of patients relapse, resulting in a therapeutic challenge. Because these patients are not curable, the goal of therapy becomes improvement in both quality and length of life. The search has therefore been to find active agents for women with recurrent disease following platinum-based chemotherapy. Outcomes Outcomes of interest included any combination of tumour response rate, progression-free survival, overall survival, adverse events, and quality of life. Methodology The medline, embase, and Cochrane Library databases were systematically searched for primary articles and practice guidelines. The resulting evidence informed the development of clinical practice recommendations. The systematic review and recommendations were approved by the Report Approval Panel of the Program in Evidence-Based Care, and by the Gynecology Cancer Disease Site Group (dsg). The practice guideline was externally reviewed by a sample of practitioners from Ontario, Canada. Results Thirteen randomized trials compared various chemotherapy regimens for patients with recurrent ovarian cancer. In five of the thirteen trials in which 100% of patients were considered sensitive to platinum-containing chemotherapy, further platinum-based combination chemotherapy significantly improved response rates (two trials), progression-free survival (four trials), and overall survival (three trials) when compared with single-agent chemotherapy involving carboplatin or paclitaxel. Only two of these randomized trials compared the same chemotherapy regimens: carboplatin alone versus the combination of carboplatin and paclitaxel. Both trials were consistent in reporting improved survival outcomes with the combination of carboplatin and paclitaxel. In one trial, the combination of carboplatin and gemcitabine resulted in significantly higher response rates and improved progression-free survival when compared with carboplatin alone. Median survival with carboplatin alone ranged from 17 months to 24 months in four trials. In eight of the thirteen trials in which 35%–100% of patients had platinum-refractory or -resistant disease, one trial reported a statistically significant 2-month improvement in overall survival with liposomal doxorubicin as compared with topotecan (15 months vs. 13 months, p = 0.038; hazard ratio: 1.23; 95% confidence interval: 1.01 to 1.50). In that trial, because of the limited clinical benefit and the unusual finding that a survival difference emerged only after a year of treatment with no corresponding improvement in the rate of response or of progression-free survival, the authors concluded that further confirmation by results from randomized trials were needed to establish the superiority of one agent over another in their trial. In one trial, topotecan was superior to treosulphan in patient progression-free survival by a span of approximately 2 months (5.4 months vs. 3.0 months, p < 0.001). Toxicity was reported in all of the randomized trials, and although data on adverse events varied by treatment regimen, the observed adverse events correlated with known toxicity profiles. As expected, combination chemotherapy was associated with higher rates of adverse events. Practice Guideline Target Population This clinical recommendation applies to women with recurrent epithelial ovarian cancer who have previously received platinum-based chemotherapy. Of specific interest are women who have previously shown sensitivity to platinum therapy and those who previously were refractory or resistant to platinum-based chemotherapy. As a general categorization within what is actually a continuum, “platinum sensitivity” refers to disease recurrence 6 months or more after prior platinum-containing chemotherapy, and “platinum resistance” refers to a response to platinum-based chemotherapy followed by relapse less than 6 months after chemotherapy is stopped. “Platinum-refractory disease” refers to a lack of response or to progression while on platinum-based chemotherapy. Recommendations Although the body of evidence that informs the clinical recommendations is based on randomized trial data, those data are incomplete. Based on the available data and expert consensus opinion, the Gynecology Cancer dsg makes these recommendations: Systemic therapy for recurrent ovarian cancer is not curative. It is therefore recognized that each patient must be individually assessed to determine optimal therapy in terms of recurrence, sensitivity to platinum, toxicity, ease of administration, and patient preference. All suitable patients should be offered the opportunity to participate in randomized trials, if available. In the absence of contraindications, combination platinum-based chemotherapy should be considered for patients with prior sensitivity to platinum-containing chemotherapy. As compared with carboplatin alone, the combination of carboplatin and paclitaxel significantly improved both progression-free and overall survival. If combination platinum-based chemotherapy is not indicated, then a single platinum agent should be considered. Carboplatin has demonstrated efficacy across trials and has a manageable toxicity profile. If a single platinum agent is not being considered, then monotherapy with paclitaxel, topotecan, or pegylated liposomal doxorubicin are seen as reasonable treatment options. Some patients may be repeatedly sensitive to treatment and may benefit from multiple lines of chemotherapy. For patients with platinum-refractory or platinum-resistant disease, the goals of treatment should be to improve quality of life by extending the symptom-free interval, by reducing symptom intensity, and by increasing progression-free interval, and, if possible, to prolong life. With non-platinum agents, monotherapy should be considered because no advantage appears to accrue to the use of non-platinum-containing combination chemotherapy in this group of patients. Single-agent paclitaxel, topotecan, or pegylated liposomal doxorubicin have demonstrated activity in this patient population and are reasonable treatment options. No evidence either supports or refutes the use of more than one line of chemotherapy in patients with platinum-refractory or platinum-resistant recurrence. Many treatment options have shown modest response rates, but their benefits over best supportive care have not been studied in clinical trials. PMID:17938703

A 77-year-old man underwent total gastrectomy with D1+ lymph node dissection after being diagnosed with cT4aN2M0, cStage ⅢB gastric cancer. Peritoneal dissemination was detected in the bursa omentalis. The pathological diagnosis after surgery was pT4aN3b (21/41) M1 (P1). He was treated with 6 courses of S-1 chemotherapy. Two years after surgery, upper gastrointestinal endoscopy revealed the presence of a tumor in the mid-thoracic esophagus. It was diagnosed to as metastatic esophageal cancer and treated with combination chemotherapy consisting of docetaxel (25 mg/m2, days 1, 8, 15) and cisplatin (25 mg/m2, days 1, 8, 15) in a 28-day cycle. A clinically complete response was observed after 5 courses of chemotherapy. Currently, the patient is alive with no signs of recurrence 12 months after the initial recurrence.

To develop a new therapeutic strategy for taxane/platinum-resistant/refractory ovarian and primary peritoneal cancers, we evaluated the feasibility and efficacy of irinotecan and gemcitabine combination chemotherapy. Patients with taxane/platinum-resistant/refractory cancer received escalating doses of irinotecan and gemcitabine (level 1: 80 and 800 mg/m 2 , respectively; level 2: 100 and 1000 mg/m 2 ) on days 1 and 8 on a 21-day cycle. Genotyping for UGT1A1*6 and *28 polymorphisms was performed for possible adverse irinotecan sensitivity. A total of 35 patients were enrolled. The recommended dose was defined as 100 mg/m 2 irinotecan and 1000 mg/m 2 gemcitabine (level 2). The observed common grade 3/4 toxicities were neutropenia (60%), anemia (17.1%), diarrhea (8.6%), thrombocytopenia (5.7%) and nausea (5.7%). Groups homozygous for UGT1A1*6 or *28 were associated with grade 3/4 neutropenia and diarrhea. Objective responses were 20%, including one complete response and six partial responses. In 29 patients treated with the recommended dose, the median progression-free survival and overall survival were 3.8 months (95% CI 2.1-6.0 months) and 17.4 months (95% CI 9.9-21.9 months), respectively, while the 1-year survival rate was 58.6%. Combination chemotherapy with irinotecan and gemcitabine represents a safe and effective treatment combination for taxane/platinum-resistant/refractory ovarian and primary peritoneal cancers.

To compare the diagnostic accuracy and sensitivity of Gd-EOB-DTPA MRI and diffusion-weighted (DWI) imaging alone and in combination for detecting colorectal liver metastases in patients who had undergone preoperative chemotherapy. Thirty-two consecutive patients with a total of 166 liver lesions were retrospectively enrolled. Of the lesions, 144 (86.8 %) were metastatic at pathology. Three image sets (1, Gd-EOB-DTPA; 2, DWI; 3, combined Gd-EOB-DTPA and DWI) were independently reviewed by two observers. Statistical analysis was performed on a per-lesion basis. Evaluation of image set 1 correctly identified 127/166 lesions (accuracy 76.5 %; 95 % CI 69.3-82.7) and 106/144 metastases (sensitivity 73.6 %, 95 % CI 65.6-80.6). Evaluation of image set 2 correctly identified 108/166 (accuracy 65.1 %, 95 % CI 57.3-72.3) and 87/144 metastases (sensitivity of 60.4 %, 95 % CI 51.9-68.5). Evaluation of image set 3 correctly identified 148/166 (accuracy 89.2 %, 95 % CI 83.4-93.4) and 131/144 metastases (sensitivity 91 %, 95 % CI 85.1-95.1). Differences were statistically significant (P < 0.001). Notably, similar results were obtained analysing only small lesions (<1 cm). The combination of DWI with Gd-EOB-DTPA-enhanced MRI imaging significantly increases the diagnostic accuracy and sensitivity in patients with colorectal liver metastases treated with preoperative chemotherapy, and it is particularly effective in the detection of small lesions.

In prior Cancer and Leukemia Group B (CALGB) studies, combined chemotherapy and thoracic irradiation was superior to chemotherapy alone in limited-disease (LD) small-cell lung cancer (SCLC). A combined modality pilot study was performed to test the feasibility of adding warfarin to aggressive chemoradiotherapy for LD SCLC. Combination chemotherapy with doxorubicin 45 mg/m2 intravenously (IV) on day 1, cyclophosphamide 800 mg/m2 IV on day 1, and etoposide (ACE) 80 mg/m2 on days 1 to 3 was given every 21 days for the first three courses. The fourth and fifth courses substituted cisplatin 33 mg/m2 IV on days 1 to 3 for the doxorubicin, with concurrent chest irradiation to a total of 4,000 cGy given in 20 fractions during a 4-week period followed by a boost of 1,000 cGy in five fractions during a 1-week period. Prophylactic cranial irradiation, 3,000 cGy was given concurrently in 10 fractions during a 2-week period. Courses 6 to 8 again used ACE chemotherapy, but courses 4 to 8 were given on a 28-day schedule with dose adjustment for hematologic or renal toxicity. Warfarin was given throughout the treatment period titrated to achieve a prothrombin time (PT) of 1.5 to 2 times the control. Patients with histologically proven limited-stage SCLC, good performance status, and normal renal, hematologic, and hepatic functions were eligible. Sixty-one of 66 patients entered onto the study were eligible and assessable. Fifty-four (89%) (95%) confidence interval [CI], 78% to 95%) experienced an objective response, 35 (57%) achieved a complete response (CR) (95% CI, 44% to 70%), and 17 (28%) achieved a partial response (95% CI, 16% to 39%). Median durations were CR, 26.3 months; failure-free survival, 11.8 months; and survival, 18 months. Forty-one percent of the patients were alive at 2 years, 33% were alive at 3 years, and 25% were alive at 4 or more years. Median follow-up for survivors is 5 years (range, 3.5 to 5.9 years). Severe or life-threatening myelosuppression occurred in 90%, infection occurred in 34%, fever without documented infection occurred in 26%, and pulmonary toxicity occurred in 6%. Another 6% of patients experienced severe or life-threatening hemorrhages. There were four treatment-related fatalities. The pulmonary toxicities have been associated with the resumption of ACE chemotherapy after chest irradiation. These highly encouraging response and survival results compare favorably with any prior CALGB group study. Although they are somewhat more toxic, they are comparable to the best published results. A randomized study that examines the role of warfarin is underway.

Background: Randomized trials established topotecan and the combination of adriamycin, cyclophosphamide and vincristine (ACO) as second-line therapy options for small-cell lung cancer. We retrospectively evaluated the outcome of SCLC patients undergoing second-line chemotherapy. Patients and Methods: 92 consecutive patients with a diagnosis of SCLC between 2000 and 2010 were analyzed. Results: 86 patients (93.5%) were evaluable for outcome analysis. All patients diagnosed with limited disease (LD) SCLC received platinum-based chemotherapy as first-line treatment. 69 patients (98.6%) diagnosed with extensive disease (ED) SCLC received first-line palliative chemotherapy. In the total cohort, the median overall survival (OS) was 10.3 months (19.2 months and 9.2 months for LD-SCLC and ED-SCLC, respectively). 42 patients received second-line therapy (ACO in 47.6% and topotecan in 31.0% of patients, respectively). Eight patients (19.0%) were re-challenged with platinum/etoposide. Neither the overall response rate (52.9% vs. 22.2%; p=0.128) nor progression-free survival (2.4 vs. 2.4 months; p=0.794) or OS (5.5 vs. 5.0 months; p=0.997) were significantly different between ACO and topotecan. ACO-treated patients showed a trend towards a longer duration of inpatient care. Conclusion: We showed similar outcomes as reported in clinical trials. Second-line combination chemotherapy with ACO did not show superiority to intravenous topotecan, but was associated with a clinically relevant longer hospitalization time. PMID:26516363

Patients with Down syndrome (DS) are more likely to develop chemotherapy-related complications. The standard treatment for these patients with cancer has not yet been established, and the risks of standard chemotherapy are unclear. In this paper, a rare case of multiple craniospinal germinomas in a patient with DS, which was successfully treated with standard-dose chemotherapy combined with craniospinal irradiation, is reported. The authors report a case of multiple craniospinal germinomas in a DS patient who presented with bilateral oculomotor and facial nerve palsy and hearing loss. The patient underwent 3 courses of combination chemotherapy using a standard dose of carboplatin and etoposide and 23.4 Gy of concurrent craniospinal irradiation. Posttreatment magnetic resonance imaging showed reduction of the tumors. Both fluorodeoxyglucose- and methionine-positron emission tomography demonstrated no uptake in the residual tumors. Follow-up magnetic resonance imaging and positron emission tomography did not reveal tumor recurrence for 18 months. As far as we know, this is the first case of multiple craniospinal germinomas in a patient with DS who achieved a successful treatment result without fatal adverse events. The literature review indicated that disseminated germinomas may need intensive treatment to reduce recurrence risk. However, intensive chemotherapy using a combination of 3 or more anticancer drugs can increase the rate of treatment-related death during the early stage. Our case indicated that multiple craniospinal germinoma of DS patients could be treated with a standard dose of carboplatin and etoposide regimen with concurrent craniospinal irradiation along with appropriate supportive therapy and careful observation.

The prognosis of people with metastatic cutaneous melanoma, a skin cancer, is generally poor. Recently, new classes of drugs (e.g. immune checkpoint inhibitors and small-molecule targeted drugs) have significantly improved patient prognosis, which has drastically changed the landscape of melanoma therapeutic management. This is an update of a Cochrane Review published in 2000. To assess the beneficial and harmful effects of systemic treatments for metastatic cutaneous melanoma. We searched the following databases up to October 2017: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase and LILACS. We also searched five trials registers and the ASCO database in February 2017, and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs). We considered RCTs of systemic therapies for people with unresectable lymph node metastasis and distant metastatic cutaneous melanoma compared to any other treatment. We checked the reference lists of selected articles to identify further references to relevant trials. Two review authors extracted data, and a third review author independently verified extracted data. We implemented a network meta-analysis approach to make indirect comparisons and rank treatments according to their effectiveness (as measured by the impact on survival) and harm (as measured by occurrence of high-grade toxicity). The same two review authors independently assessed the risk of bias of eligible studies according to Cochrane standards and assessed evidence quality based on the GRADE criteria. We included 122 RCTs (28,561 participants). Of these, 83 RCTs, encompassing 21 different comparisons, were included in meta-analyses. Included participants were men and women with a mean age of 57.5 years who were recruited from hospital settings. Twenty-nine studies included people whose cancer had spread to their brains. Interventions were categorised into five groups: conventional chemotherapy (including single agent and polychemotherapy), biochemotherapy (combining chemotherapy with cytokines such as interleukin-2 and interferon-alpha), immune checkpoint inhibitors (such as anti-CTLA4 and anti-PD1 monoclonal antibodies), small-molecule targeted drugs used for melanomas with specific gene changes (such as BRAF inhibitors and MEK inhibitors), and other agents (such as anti-angiogenic drugs). Most interventions were compared with chemotherapy. In many cases, trials were sponsored by pharmaceutical companies producing the tested drug: this was especially true for new classes of drugs, such as immune checkpoint inhibitors and small-molecule targeted drugs.When compared to single agent chemotherapy, the combination of multiple chemotherapeutic agents (polychemotherapy) did not translate into significantly better survival (overall survival: HR 0.99, 95% CI 0.85 to 1.16, 6 studies, 594 participants; high-quality evidence; progression-free survival: HR 1.07, 95% CI 0.91 to 1.25, 5 studies, 398 participants; high-quality evidence. Those who received combined treatment are probably burdened by higher toxicity rates (RR 1.97, 95% CI 1.44 to 2.71, 3 studies, 390 participants; moderate-quality evidence). (We defined toxicity as the occurrence of grade 3 (G3) or higher adverse events according to the World Health Organization scale.)Compared to chemotherapy, biochemotherapy (chemotherapy combined with both interferon-alpha and interleukin-2) improved progression-free survival (HR 0.90, 95% CI 0.83 to 0.99, 6 studies, 964 participants; high-quality evidence), but did not significantly improve overall survival (HR 0.94, 95% CI 0.84 to 1.06, 7 studies, 1317 participants; high-quality evidence). Biochemotherapy had higher toxicity rates (RR 1.35, 95% CI 1.14 to 1.61, 2 studies, 631 participants; high-quality evidence).With regard to immune checkpoint inhibitors, anti-CTLA4 monoclonal antibodies plus chemotherapy probably increased the chance of progression-free survival compared to chemotherapy alone (HR 0.76, 95% CI 0.63 to 0.92, 1 study, 502 participants; moderate-quality evidence), but may not significantly improve overall survival (HR 0.81, 95% CI 0.65 to 1.01, 2 studies, 1157 participants; low-quality evidence). Compared to chemotherapy alone, anti-CTLA4 monoclonal antibodies is likely to be associated with higher toxicity rates (RR 1.69, 95% CI 1.19 to 2.42, 2 studies, 1142 participants; moderate-quality evidence).Compared to chemotherapy, anti-PD1 monoclonal antibodies (immune checkpoint inhibitors) improved overall survival (HR 0.42, 95% CI 0.37 to 0.48, 1 study, 418 participants; high-quality evidence) and probably improved progression-free survival (HR 0.49, 95% CI 0.39 to 0.61, 2 studies, 957 participants; moderate-quality evidence). Anti-PD1 monoclonal antibodies may also result in less toxicity than chemotherapy (RR 0.55, 95% CI 0.31 to 0.97, 3 studies, 1360 participants; low-quality evidence).Anti-PD1 monoclonal antibodies performed better than anti-CTLA4 monoclonal antibodies in terms of overall survival (HR 0.63, 95% CI 0.60 to 0.66, 1 study, 764 participants; high-quality evidence) and progression-free survival (HR 0.54, 95% CI 0.50 to 0.60, 2 studies, 1465 participants; high-quality evidence). Anti-PD1 monoclonal antibodies may result in better toxicity outcomes than anti-CTLA4 monoclonal antibodies (RR 0.70, 95% CI 0.54 to 0.91, 2 studies, 1465 participants; low-quality evidence).Compared to anti-CTLA4 monoclonal antibodies alone, the combination of anti-CTLA4 plus anti-PD1 monoclonal antibodies was associated with better progression-free survival (HR 0.40, 95% CI 0.35 to 0.46, 2 studies, 738 participants; high-quality evidence). There may be no significant difference in toxicity outcomes (RR 1.57, 95% CI 0.85 to 2.92, 2 studies, 764 participants; low-quality evidence) (no data for overall survival were available).The class of small-molecule targeted drugs, BRAF inhibitors (which are active exclusively against BRAF-mutated melanoma), performed better than chemotherapy in terms of overall survival (HR 0.40, 95% CI 0.28 to 0.57, 2 studies, 925 participants; high-quality evidence) and progression-free survival (HR 0.27, 95% CI 0.21 to 0.34, 2 studies, 925 participants; high-quality evidence), and there may be no significant difference in toxicity (RR 1.27, 95% CI 0.48 to 3.33, 2 studies, 408 participants; low-quality evidence).Compared to chemotherapy, MEK inhibitors (which are active exclusively against BRAF-mutated melanoma) may not significantly improve overall survival (HR 0.85, 95% CI 0.58 to 1.25, 3 studies, 496 participants; low-quality evidence), but they probably lead to better progression-free survival (HR 0.58, 95% CI 0.42 to 0.80, 3 studies, 496 participants; moderate-quality evidence). However, MEK inhibitors probably have higher toxicity rates (RR 1.61, 95% CI 1.08 to 2.41, 1 study, 91 participants; moderate-quality evidence).Compared to BRAF inhibitors, the combination of BRAF plus MEK inhibitors was associated with better overall survival (HR 0.70, 95% CI 0.59 to 0.82, 4 studies, 1784 participants; high-quality evidence). BRAF plus MEK inhibitors was also probably better in terms of progression-free survival (HR 0.56, 95% CI 0.44 to 0.71, 4 studies, 1784 participants; moderate-quality evidence), and there appears likely to be no significant difference in toxicity (RR 1.01, 95% CI 0.85 to 1.20, 4 studies, 1774 participants; moderate-quality evidence).Compared to chemotherapy, the combination of chemotherapy plus anti-angiogenic drugs was probably associated with better overall survival (HR 0.60, 95% CI 0.45 to 0.81; moderate-quality evidence) and progression-free survival (HR 0.69, 95% CI 0.52 to 0.92; moderate-quality evidence). There may be no difference in terms of toxicity (RR 0.68, 95% CI 0.09 to 5.32; low-quality evidence). All results for this comparison were based on 324 participants from 2 studies.Network meta-analysis focused on chemotherapy as the common comparator and currently approved treatments for which high- to moderate-quality evidence of efficacy (as represented by treatment effect on progression-free survival) was available (based on the above results) for: biochemotherapy (with both interferon-alpha and interleukin-2); anti-CTLA4 monoclonal antibodies; anti-PD1 monoclonal antibodies; anti-CTLA4 plus anti-PD1 monoclonal antibodies; BRAF inhibitors; MEK inhibitors, and BRAF plus MEK inhibitors. Analysis (which included 19 RCTs and 7632 participants) generated 21 indirect comparisons.The best evidence (moderate-quality evidence) for progression-free survival was found for the following indirect comparisons:• both combinations of immune checkpoint inhibitors (HR 0.30, 95% CI 0.17 to 0.51) and small-molecule targeted drugs (HR 0.17, 95% CI 0.11 to 0.26) probably improved progression-free survival compared to chemotherapy;• both BRAF inhibitors (HR 0.40, 95% CI 0.23 to 0.68) and combinations of small-molecule targeted drugs (HR 0.22, 95% CI 0.12 to 0.39) were probably associated with better progression-free survival compared to anti-CTLA4 monoclonal antibodies;• biochemotherapy (HR 2.81, 95% CI 1.76 to 4.51) probably lead to worse progression-free survival compared to BRAF inhibitors;• the combination of small-molecule targeted drugs probably improved progression-free survival (HR 0.38, 95% CI 0.21 to 0.68) compared to anti-PD1 monoclonal antibodies;• both biochemotherapy (HR 5.05, 95% CI 3.01 to 8.45) and MEK inhibitors (HR 3.16, 95% CI 1.77 to 5.65) were probably associated with worse progression-free survival compared to the combination of small-molecule targeted drugs; and• biochemotherapy was probably associated with worse progression-free survival (HR 2.81, 95% CI 1.54 to 5.11) compared to the combination of immune checkpoint inhibitors.The best evidence (moderate-quality evidence) for toxicity was found for the following indirect comparisons:• combination of immune checkpoint inhibitors (RR 3.49, 95% CI 2.12 to 5.77) probably increased toxicity compared to chemotherapy;• combination of immune checkpoint inhibitors probably increased toxicity (RR 2.50, 95% CI 1.20 to 5.20) compared to BRAF inhibitors;• the combination of immune checkpoint inhibitors probably increased toxicity (RR 3.83, 95% CI 2.59 to 5.68) compared to anti-PD1 monoclonal antibodies; and• biochemotherapy was probably associated with lower toxicity (RR 0.41, 95% CI 0.24 to 0.71) compared to the combination of immune checkpoint inhibitors.Network meta-analysis-based ranking suggested that the combination of BRAF plus MEK inhibitors is the most effective strategy in terms of progression-free survival, whereas anti-PD1 monoclonal antibodies are associated with the lowest toxicity.Overall, the risk of bias of the included trials can be considered as limited. When considering the 122 trials included in this review and the seven types of bias we assessed, we performed 854 evaluations only seven of which (< 1%) assigned high risk to six trials. We found high-quality evidence that many treatments offer better efficacy than chemotherapy, especially recently implemented treatments, such as small-molecule targeted drugs, which are used to treat melanoma with specific gene mutations. Compared with chemotherapy, biochemotherapy (in this case, chemotherapy combined with both interferon-alpha and interleukin-2) and BRAF inhibitors improved progression-free survival; BRAF inhibitors (for BRAF-mutated melanoma) and anti-PD1 monoclonal antibodies improved overall survival. However, there was no difference between polychemotherapy and monochemotherapy in terms of achieving progression-free survival and overall survival. Biochemotherapy did not significantly improve overall survival and has higher toxicity rates compared with chemotherapy.There was some evidence that combined treatments worked better than single treatments: anti-PD1 monoclonal antibodies, alone or with anti-CTLA4, improved progression-free survival compared with anti-CTLA4 monoclonal antibodies alone. Anti-PD1 monoclonal antibodies performed better than anti-CTLA4 monoclonal antibodies in terms of overall survival, and a combination of BRAF plus MEK inhibitors was associated with better overall survival for BRAF-mutated melanoma, compared to BRAF inhibitors alone.The combination of BRAF plus MEK inhibitors (which can only be administered to people with BRAF-mutated melanoma) appeared to be the most effective treatment (based on results for progression-free survival), whereas anti-PD1 monoclonal antibodies appeared to be the least toxic, and most acceptable, treatment.Evidence quality was reduced due to imprecision, between-study heterogeneity, and substandard reporting of trials. Future research should ensure that those diminishing influences are addressed. Clinical areas of future investigation should include the longer-term effect of new therapeutic agents (i.e. immune checkpoint inhibitors and targeted therapies) on overall survival, as well as the combination of drugs used in melanoma treatment; research should also investigate the potential influence of biomarkers.

Increased recruitment of tumor-associated macrophages (TAM) to tumors following chemotherapy promotes tumor resistance and recurrence and correlates with poor prognosis. TAM depletion suppresses tumor growth, but is not highly effective due to the effects of tumorigenic mediators from other stromal sources. Here, we report that adoptive macrophage transfer led to a dramatically enhanced photodynamic therapy (PDT) effect of 2-(1-hexyloxyethyl)-2-devinyl pyropheophor-bide-alpha (HPPH)-coated polyethylene glycosylated nanographene oxide [GO(HPPH)-PEG] by increasing its tumor accumulation. Moreover, tumor treatment with commonly used chemotherapeutic drugs induced an increase in macrophage infiltration into tumors, which also enhanced tumor uptake and the PDT effects of GO(HPPH)-PEG, resulting in tumor eradication. Macrophage recruitment to tumors after chemotherapy was visualized noninvasively by near-infrared fluorescence and single-photon emission CT imaging using F4/80-specific imaging probes. Our results demonstrate that chemotherapy combined with GO(HPPH)-PEG PDT is a promising strategy for the treatment of tumors, especially those resistant to chemotherapy. Furthermore, TAM-targeted molecular imaging could potentially be used to predict the efficacy of combination therapy and select patients who would most benefit from this treatment approach.

The aim was to evaluate the effects of traditional Chinese medicine (TCM) as a combination medication with adjuvant chemotherapy on postoperative early stage non-small cell lung cancer (NSCLC) patients. The 314 patients with completely resected stage IB, II or IIIA cancers were assigned into vinorelbine plus cisplatin/carboplatin (NP/NC) (control, n = 158) and NP/NC with additional TCM (intervention, n = 156) groups. The primary endpoint was QOL scores; secondary endpoints were the toxicity and safety of the regimens. The NP/NC regimen caused mild (grade 1 or 2) non-hematologic toxic effects in the patients comprising vomiting (43.6%), fatigue (36.9%), pain (23%), dry mouth (27.6%) and diarrhea (7.9%). The incidence of adverse events was significantly lower in the intervention group than in the control group (0.57% vs 4.02%, P = 0.037). Transient severe (grade 3 or 4) hematological toxic effects occurred less often (hemoglobin reduction (11.9 vs 22.5 percent) and total bilirubin increased (to 42.1 vs 46.2%) in the intervention compared to the control group during the 2nd chemotherapy cycle. When combined with adjuvant chemotherapy, TCM led to partial relief of symptoms in addition to a reduction of side-effects and adverse events caused by the NP/NC regimens. PMID:28436479

The efficacy of second or third-line chemotherapy in advanced non-small cell lung cancer (NSCLC) patients is low. The use of targeted drugs brings survival benefit for some patients. Apatinib, as a novel small molecule antiangiogenic drug, has demonstrated satisfactory anticancer activity across a broad range of malignancies. The aim of this study is to evaluate the efficacy and safety of apatinib in patients with advanced NSCLC after first-line treatment failure. A retrospective study of 128 patients was conducted to evaluate the safety, short-term efficacy and survival status with different regimens. Kaplan-Meier method and Cox regression model were used for analysis. Compared with chemotherapy alone, the median progression free survival (PFS) in apatinib monotherapy, chemotherapy alone and apatinib combined with chemotherapy were 3.0 (P=0.381), 3.7 and 6.0 months (P<0.001), respectively. The median overall survival (OS) were 6.0 (P=0.494), 6.5 and 9.0 months (P=0.001), respectively. The incidence of adverse events in grades 3-4 were 18.5%, 15.8% and 16.0%, respectively (P=0.947). Different treatment regimens (P=0.018) and performance status (PS)(P<0.001) were the independent factors of PFS. The smoking history (P=0.014), treatment regimens (P=0.002) and PS (P<0.001) were independent influencing factors of OS. Apatinib has a good security. After first-line treatment failure of lung cancer, chemotherapy combined with apatinib in second or third-line is beneficial in PFS and OS when compared with chemotherapy alone. But when making comparison between apatinib monotherapy and chemotherapy alone, there is no significant difference in PFS and OS. Patients who never smoke or has a better PS or use combination therapy have longer survival time.

Mycobacterium indicus pranii (MIP) already established as an immune-modulator in mycobacterial infections generates immune response by acting on CXC chemokines. In the present study, the immunomodulatory effect of MIP in conjunction with chemotherapy against M.tb infection was evaluated by colony forming units (CFUs) following aerosol infection to guinea pig and by measuring CXCL12 chemokine expression using q-PCR and in situ RT-PCR. Different experimental groups included, infection (Rv), immunoprophylaxis (RvMw), chemotherapy (RvCh) and combination of immunoprophylaxis+chemotherapy (RvChMw) group and normal healthy (NH) group. In the combination of immunoprophylaxis+chemotherapy (RvChMw) group, the CFU counts reduced significantly (p<0.001) at 4th week of infection as compared to other treated groups (RvMw and RvCh group). The expression of CXCL12 was recorded in all the treated groups of animals. The study demonstrated suppressed expression of CXCL 12 in both immunoprophylaxis as well as chemotherapy groups (6th and 8th week) that become elevated in immunoprophylaxis plus chemotherapy group (10th week), at which time point no CFUs were detected in RvCh and RvChMw group. The findings indicate that the expression of CXCL12 is associated with good response to anti - tubercular treatment. Thus, prior immunization with MIP appears to show good immunomodulatory effect to release CXCL12 chemokine during infection and also correlates with enhanced effect to chemotherapy.

To evaluate the safety and efficacy of combining Endostar antiangiogenic therapy with neoadjuvant chemotherapy for the treatment of stage IIIA (N2) NSCLC, we conducted a randomized, controlled, open-label clinical study of 30 NSCLC patients. Patients were randomly assigned to the test or control groups, which received either two cycles of an NP neoadjuvant chemotherapy regimen combined with Endostar or the NP regimen alone, respectively, at a 2:1 ratio. Efficacy was assessed after 3 weeks, and surgical resection occurred within 4 weeks, in the 26 patients who successfully completed treatment. While total response rates (RR) and clinical benefit rates (CBR) did not differ between the experimental groups, total tumor regression rates (TRR) were higher in the test group than in the control group. Median DFS and OS also did not differ between the test and control groups. Clinical perioperative indicators, including intraoperative blood loss, number of dissected lymph node groups, duration of postoperative indwelling catheter use, and time to postoperative discharge, were comparable in the test and control groups. Finally, hematological and non-hematological toxicities and postoperative pathological indicators, including down-staging ratio, complete resection ratio, and metastatic lymph node ratio, also did not differ between the groups. Overall, combining Endostar with NP neoadjuvant chemotherapy increased therapeutic efficacy without increasing adverse effects in stage IIIA-N2 NSCLC patients. This study is registered with ClinicalTrials.gov (number NCT02497118).

The influence of a plant preparation AdMax (Nulab Inc., Clearwater, FL, USA) on immunity in ovarian cancer patients was studied. The preparation is a combination of dried ethanol/water extracts from roots of Leuzea carthamoides, Rhodiola rosea, Eleutherococcus senticosus and fruits of Schizandra chinensis. Twenty eight patients with stage III-IV epithelial ovarian cancer were treated once with 75 mg/m(2) cisplatin and 600 mg/m(2) cyclophosphamide. Peripheral blood was collected 4 weeks after the chemotherapy. Subclasses of T, B and NK lymphocytes were tested for in the blood samples: CD3, CD4, CD5, CD7, CD8, CD11B, CD16, CD20, CD25, CD38, CD45RA, CD50, CD71 and CD95. Immunoglobulin G, A and M concentrations were also determined. Changes were observed in the following T cell subclasses: CD3, CD4, CD5 and CD8. In patients who took AdMax (270 mg a day) for 4 weeks following the chemotherapy, the mean numbers of the four T cell subclasses were increased in comparison with the mean numbers of the T cell subclasses in patients who did not take AdMax. In patients who took AdMax, the mean amounts of IgG and IgM were also increased. The obtained results suggest that the combination of extracts from adaptogenic plants may boost the suppressed immunity in ovarian cancer patients who are subject to chemotherapy.

Angiogenesis plays an important role in the biology of ovarian cancer. The clinical efficacy and side effects of bevacizumab, the vascular endothelial growth factor inhibitor, on survival and toxicity in women with this ovarian cancer, was not conclusive. We performed this systematic review and meta-analysis in order to clarify the efficacy of bevacizumab combined with chemotherapy in the treatment of ovarian cancer. We searched the electronic database of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and CNKI for clinical controlled trials of comparing bevacizumab combined with chemotherapy and chemotherapy alone in the treatment of ovarian cancer. The primary outcomes of eligible studies included median progression-free survival (PFS), overall survival (OS), and toxicities such as enterobrosis, hypertension, albuminuria, congestive heart failure (CHF), neutrophils, thrombosis, and bleeding. The Hazard ratio (HR) and relative risk were used for the meta-analysis and were expressed with 95% confidence intervals (CIs). All the statistical analyses were carried out by  Stata 11.0 software (http://www.stata.com; Stata Corporation, College Station, TX, USA). We included 5 studies with 1798 cases in the bevacizumab combined with the chemotherapy group and 1810 subjects in the chemotherapy alone group. The pooled results showed that bevacizumab + chemotherapy compared with chemotherapy alone can significant prolong the median PFS (HR, 0.64; 95% CI, 0.46-0.82; P < 0.05) but not the OS (HR, 0.84; 95% CI, 0.59-10.9; P > 0.05); the toxicity analysis showed that the enterobrosis, hypertension, albuminuria, neutrophils, thrombosis, and bleeding were significantly increased in the bevacizumab + chemotherapy group compared with chemotherapy alone (Pall < 0.05). But the CHF risk between the two groups was not statistical different (P > 0.05). Bevacizumab combined with chemotherapy prolonged the median PFS in patients with ovarian cancer but also increase the risk of developing enterobrosis, hypertension, albuminuria, neutrophils, thrombosis, and bleeding.

We report the synthesis of smart nanoparticles (NPs) that generate heat in response to an alternating current magnetic field (ACMF) and that sequentially release an anticancer drug (doxorubicin, DOX). We further study the in vivo therapeutic efficacy of the combination of magnetic hyperthermia (MHT) and chemotherapy using the smart NPs for the treatment of multiple myeloma. The smart NPs are composed of a polymer with a glass-transition temperature (T g) of 44°C, which contains clustered Fe3O4 NPs and DOX. The clustered Fe3O4 NPs produce heat when the ACMF is applied and rise above 44°C, which softens the polymer phase and leads to the release of DOX. The combination of MHT and chemotherapy using the smart NPs destroys cancer cells in the entire tumor and achieves a complete cure in one treatment without the recurrence of malignancy. Furthermore, the smart NPs have no significant toxicity.

To investigate the therapeutical effect and side-effect of docetaxel combined with cisplatin (DDP) on the treatment of local advanced esophageal cancer with concomitant radiation therapy. Ninety patients with LOCAL advanced esophageal squamous cell carcinoma were divided into two groups: (DDP + 5-Fu) group and (docetaxel + DDP) group. Chemotherapy was carried out every 4 weeks for a total of 4 courses. The radiation dose was 50.4 Gy/28FX. The median survival time of patients in the (DDP + 5-Fu) group was 16 months and that in (docetaxel + DDP) group was 21 months (P = 0.0278). The 3-year survival rate in the (docetaxel + DDP) group was obviously higher than that in the (DDP + 5-Fu) group (23.9% vs. 12.1%). The ORR in (docetaxel + DDP) group (84.5%) was significantly higher than that in the (DDP + 5-Fu) group (71.1%) (P = 0.025). No significant differences were observed in the incidence of side-effects in the two groups. The conventional dose chemotherapy of docetaxel + DDP with concomitant radiation therapy showed a better partial remission rate and long-term survival rate for the treatment of local advanced esophageal cancer than the traditional chemotherapy (DDP + 5-Fu) with concomitant radiation therapy and the side-effects are not increased.

Abstract Rationale: The standard treatment for ovarian cancer is chemotherapy with 2 drugs (taxanes and platinum drugs). However, the traditional combination of the 2 drugs has many adverse effects (AEs) and the cancer cells will quickly become resistant to the drugs. Apatinib is a small-molecule antiangiogenic agent which has shown promising therapeutic effects against diverse tumor types, but it still remains unknown whether apatinib has an antitumor effect in patients with ovarian cancer. Herein, we present a successfully treated case of ovarian cancer using chemotherapy and apatinib, in order to demonstrate the effectiveness of this new combined regimen in ovarian cancer. Patients concerns: A 51-year-old Chinese woman presented with ovarian cancer >4.5 years. The disease and the cancer antigen 125 (CA-125) had been controlled well by surgical treatment and following chemotherapy. However, the drugs could not control the disease anymore as the CA-125 level was significantly increasing. Diagnosis: Ovarian cancer. Interventions: The patient was treated with apatinib combined with epirubicin. Apatinib was administered orally, at an initial daily dose of 500 mg, and was then reduced to 250 mg qd after the appearance of intolerable hand–foot syndrome (HFS) and oral ulcer. Then, the oral ulcer disappeared and the HFS was controlled by dose adjustment, oral vitamin B6, and hand cream application. Outcomes: The CA-125 reverted to the normal value after treatment with the new regimen. Magnetic resonance imaging showed that the original tumor lesions had disappeared. Apatinib monotherapy as maintenance therapy was then used to successfully control the cancer with a complete response. Our study is the first, to our knowledge, to report the therapeutic effects of apatinib and epirubicin on ovarian cancer. Lessons: Apatinib combined with chemotherapy and apatinib monotherapy as maintenance therapy could be a new therapeutic strategy for ovarian cancer, especially adenocarcinomas. PMID:29137078

Purpose: To evaluate the prognostic factors and treatment outcome of patients with Askin-Rosai tumor of the chest wall treated at a single institution. Methods and Materials: Treatment comprised multiagent chemotherapy and local therapy, which was either in the form of surgery alone, radical external-beam radiotherapy (EBRT) alone, or a combination of surgery and EBRT. Thirty-two patients (40%) were treated with all three modalities, 21 (27%) received chemotherapy and radical EBRT, and 19 (24%) underwent chemotherapy followed by surgery only. Results: One hundred four consecutive patients aged 3-60 years were treated at the Tata Memorial Hospital from January 1995 to Octobermore » 2003. Most (70%) were male (male/female ratio, 2.3:1). Asymptomatic swelling (43%) was the most common presenting symptom, and 25% of patients presented with distant metastasis. After a median follow-up of 28 months, local control, disease-free survival, and overall survival rates were 67%, 36%, and 45%, respectively. Median time to relapse was 25 months, and the median survival was 76 months. Multivariate analysis revealed age {>=}18 years, poor response to induction chemotherapy, and presence of pleural effusion as indicators of inferior survival. Fifty-six percent of patients with metastatic disease at presentation died within 1 month of diagnosis, with 6-month and 5-year actuarial survival of 14% and 4%, respectively. Conclusion: Primary tumor size, pleural effusion, response to chemotherapy, and optimal radiotherapy were important prognostic factors influencing outcome. The combination of neoadjuvant chemotherapy, surgery, and radiotherapy resulted in optimal outcome.« less

Objective. To investigate the effects of Jianpi Bushen (JPBS), a traditional Chinese medicine that is used to invigorate the spleen and tonify the kidney, combined with chemotherapy for the treatment of gastric cancer. Methods. Literature retrieval was performed in PubMed, EMBASE, Cochrane Library, MEDLINE, CNKI, Wanfang Data Information Site, and VIP from inception to October 2017. Randomized controlled trials to evaluate the effects of JPBS combined with chemotherapy were identified. The primary reported outcomes were KPS (Karnofsky Performance Status), clinical curative efficiency, immune function, blood system, and nonhematologic system. Review Manager 5.3 (RevMan 5.3) was used for data analysis, and the quality of the studies was also appraised. Results. A total of 26 studies were included with 3098 individuals. The results of the meta-analysis indicated that treatment of gastric cancer with the combination of JPBS and chemotherapy resulted in better outcomes compared to chemotherapy alone. Conclusion. Evidence from the meta-analysis suggested that JPBS combined with chemotherapy has a positive effect on gastric cancer treatment. However, additional rigorously designed and large sample randomized controlled trials are required to confirm the efficacy and safety of this treatment. PMID:29675052

The purpose of this study was to evaluate, retrospectively, the clinical efficacy of preoperative transcatheter arterial chemoembolization (TACE) combined with systemic chemotherapy for unresectable hepatoblastoma. Five boys and three girls (mean age 15.2 months) were treated with preoperative TACE combined with systemic chemotherapy for unresectable hepatoblastomas. Mean tumor diameter and mean alfa-fetoprotein (AFP) level were 11.8 cm and 549,386 ng/mL, respectively. Pretreatment, the extent of disease (PRETEXT) was: II, 1; III, 6; IV, 1. For all patients, preoperative systemic chemotherapy was administered before TACE. At each TACE, carboplatin and adriamycin mixed with iodized oil were infused into the feeding arteries. Tumor response and prognosis after treatment were evaluated. TACE resulted in few Grade 1 adverse effects (AEs), without G3 or more AEs, according to CTACAE 3.0. Mean tumor shrinkage was 60.9%, and the mean AFP decrease from initial levels was 94.8%. In all cases TACE combined with systemic chemotherapy enabled subsequent safe and complete surgical resection. After a mean follow-up of 59 months, tumor-free survival was 75%. Preoperative TACE combined with systemic chemotherapy was effective in inducing surgical resectability of unresectable hepatoblastoma.

Nanoparticle (NP)-based combination chemotherapy has been proposed as an effective strategy for achieving synergistic effects and targeted drug delivery for colon cancer therapy. Here, we fabricated a series of hyaluronic acid (HA)-functionalized camptothecin (CPT)/curcumin (CUR)-loaded polymeric NPs (HA-CPT/CUR-NPs) with various weight ratios of CPT to CUR (1 : 1, 2 : 1 and 4 : 1). The resultant spherical HA-CPT/CUR-NPs had a desirable particle size (around 289 nm), relative narrow size distribution, and slightly negative zeta potential. These NPs exhibited a simultaneous sustained release profile for both drugs throughout the time frame examined. Subsequent cellular uptake experiments demonstrated that the introduction of HA to the NP surface endowed NPs with colon cancer-targeting capability and markedly increased cellular uptake efficiency compared with chitosan-coated NPs. Importantly, the combined delivery of CPT and CUR in one HA-functionalized NP exerted strong synergistic effects. HA-CPT/CUR-NP (1 : 1) showed the highest antitumor activity among the three HA-CPT/CUR-NPs, resulting in an extremely low combination index. Collectively, our findings indicate that this HA-CPT/CUR-NP can be exploited as an efficient formulation for colon cancer-targeted combination chemotherapy.Nanoparticle (NP)-based combination chemotherapy has been proposed as an effective strategy for achieving synergistic effects and targeted drug delivery for colon cancer therapy.

Epstein-Barr virus (EBV)-positive aggressive natural killer-cell leukemia (ANKL) is a rare malignancy of mature natural killer cells, with a very poor survival rate. Patients have a rapidly declining clinical course and a poor prognosis, with a median survival of only a few months. Herein, we describe a 16-year-old boy who was diagnosed with EBV-positive ANKL and successfully treated using combination chemotherapy and a subsequent allogeneic hematopoietic stem cell transplantation (alloHSCT). The patient is disease free 4 years and 9 months after alloHSCT. Thus, combination chemotherapy followed by alloHSCT seems to be a promising therapeutic option for EBV-positive ANKL.

The outcomes for patients with esophageal cancer (EC) underwent standard-dose radical radiotherapy were still disappointing. This phase II study investigated the feasibility, safety and efficacy of radiation dose escalation using simultaneous modulated accelerated radiotherapy (SMART) combined with chemotherapy in 60 EC patients. Radiotherapy consisted of 66Gy at 2.2 Gy/fraction to the gross tumor and 54Gy at 1.8 Gy/fraction to subclinical diseases simultaneously. Chemotherapy including cisplatin and 5fluorouracil were administered to all patients during and after radiotherapy. The data showed that the majority of patients (98.3%) completed the whole course of radiotherapy and concurrent chemotherapy. The most common ≥ grade 3 acute toxicities were neutropenia (16.7%), followed by esophagitis (6.7%) and thrombopenia (5.0%). With a median follow-up of 24 months (5-38) for all patients and 30 months (18-38) for those still alive, 11 patients (18.3%) developed ≥ Grade 3 late toxicities and 2 (3.3%) of them died subsequently due to esophageal hemorrhage. The 1- and 2-year local-regional control, distant metastasis-free survival, disease-free survival and overall survival rates were 87.6% and 78.6%, 86.0% and 80.5%, 75.6% and 64.4%, 86.7% and 72.7%, respectively. SMART combined with concurrent chemotherapy is feasible in EC patients with tolerable acute toxicities. They showed a trend of significant improvements in local-regional control and overall survival. Further follow-up is needed to evaluate the late toxicities.

Adrenocortical carcinoma (ACC) is rare and confers an unfavorable prognosis in advanced stages. Other than combination chemotherapy with cisplatin, etoposide, doxorubicin, and mitotane, the second- and third-line regimens are not well-established. Gemcitabine (GEM)-based chemotherapy was suggested in a phase 2 clinical trial with 28 patients. In other solid tumors, human equilibrative nucleoside transporter type 1 (hENT1) and/or ribonucleotide reductase catalytic subunit M1 (RRM1) expression have been associated with resistance to GEM. To assess the efficacy of GEM-based chemotherapy in ACC in a real-world setting and the predictive role of molecular parameters. Retrospective multicenter study. Referral centers of university hospitals. A total of 145 patients with advanced ACC were treated with GEM-based chemotherapy (132 with concomitant capecitabine). Formalin-fixed paraffin-embedded tumor material was available for 70 patients for immunohistochemistry. The main outcome measures were progression-free survival (PFS) and an objective response to GEM-based chemotherapy. The secondary objective was the predictive role of hENT1 and RRM1. The median PFS for the patient population was 12 weeks (range, 1 to 94). A partial response or stable disease was achieved in 4.9% and 25.0% of cases, with a median duration of 26.8 weeks. Treatment was generally well tolerated, with adverse events of grade 3 or 4 occurring in 11.0% of cases. No substantial effect of hENT1 and/or RRM1 expression was observed in response to GEM-based chemotherapy. GEM-based chemotherapy is a well-tolerated, but modestly active, regimen against advanced ACC. No reliable molecular predictive factors could be identified. Owing to the scarce alternative therapeutic options, GEM-based chemotherapy remains an important option for salvage treatment for advanced ACC. Copyright © 2017 Endocrine Society

Comparison of efficacy and tolerance between combination therapy and monotherapy as first-line chemotherapy in elderly patients with advanced gastric cancer: Study protocol for a randomized controlled trial.

The combination of a fluoropyrimidine [5-fluorouracil (5-FU), capecitabine, or S-1] with a platinum analog (cisplatin or oxaliplatin) is the most widely accepted first-line chemotherapy regimen for metastatic or recurrent advanced gastric cancer (AGC), based on the results of clinical trials. However, there is little evidence to guide chemotherapy for elderly patients with AGC because of under-representation of this age group in clinical trials. Thus, the aim of this study is to determine the optimal chemotherapy regimen for elderly patients with AGC by comparing the efficacies and safeties of combination therapy versus monotherapy as first-line chemotherapy. This study is a randomized, controlled, multicenter, phase III trial. A total of 246 elderly patients (≥70 years old) with metastatic or recurrent AGC who have not received previous palliative chemotherapy will be randomly allocated to a combination therapy group or a monotherapy group. Patients randomized to the combination therapy group will receive fluoropyrimidine plus platinum combination chemotherapy (capecitabine/cisplatin, S-1/cisplatin, capecitabine/oxaliplatin, or 5-FU/oxaliplatin), and those randomized to the monotherapy group will receive fluoropyrimidine monotherapy (capecitabine, S-1, or 5-FU). The primary outcome is the overall survival of patients in each treatment group. The secondary outcomes include progression-free survival, response rate, quality of life, and safety. We are conducting this pragmatic trial to determine whether elderly patients with AGC will obtain the same benefit from chemotherapy as younger patients. We expect that this study will help guide decision-making for the optimal treatment of elderly patients with AGC.

Although adjuvant chemotherapy has made some progress in the treatment of colorectal cancer, chemotherapy of metastatic disease remains disappointing. Autologous bone marrow or stem cell transplantation following supralethal chemotherapy is presently not of major significance in tumors of the intestine. The registry of the EBMT (European Cooperative Group for Blood and Marrow Transplantation) contains at March 1993 a total of 2085 cases of autotransplants for solid tumors, of which only 19 were performed for disseminated gastrointestinal cancer (15 gastric, 4 colon). It remains to be shown, whether the presently poor results can be improved upon inclusion of lymphokine-activated killer cells (LAK-cells) by use of cytokine combinations or by the use of tumor infiltrating lymphocytes (TIL) post transplantation.

Although neuroendocrine tumors (NETs) are slow growing, they are frequently metastatic at the time of discovery and no longer amenable to curative surgery, emphasizing the need for the development of other treatments. In this study, multifunctional upconversion nanoparticle (UCNP)-based theranostic micelles are developed for NET-targeted and near-infrared (NIR)-controlled combination chemotherapy and photodynamic therapy (PDT), and bioimaging. The theranostic micelle is formed by individual UCNP functionalized with light-sensitive amphiphilic block copolymers poly(4,5-dimethoxy-2-nitrobenzyl methacrylate)-polyethylene glycol (PNBMA-PEG) and Rose Bengal (RB) photosensitizers. A hydrophobic anticancer drug, AB3, is loaded into the micelles. The NIR-activated UCNPs emit multiple luminescence bands, including UV, 540 nm, and 650 nm. The UV peaks overlap with the absorption peak of photocleavable hydrophobic PNBMA segments, triggering a rapid drug release due to the NIR-induced hydrophobic-to-hydrophilic transition of the micelle core and thus enabling NIR-controlled chemotherapy. RB molecules are activated via luminescence resonance energy transfer to generate 1 O 2 for NIR-induced PDT. Meanwhile, the 650 nm emission allows for efficient fluorescence imaging. KE108, a true pansomatostatin nonapeptide, as an NET-targeting ligand, drastically increases the tumoral uptake of the micelles. Intravenously injected AB3-loaded UCNP-based micelles conjugated with RB and KE108-enabling NET-targeted combination chemotherapy and PDT-induce the best antitumor efficacy.

We performed PMU hepatic arterial chemotherapy (a combination therapy consisting of intra-hepatic arterial infusion of CDDP and MMC, oral administration of UFT) in 20 patients with gastric cancer and liver metastases. In this method, 1-6 courses of one infusion of CDDP at 70-100 mg/body and MMC of 10 mg/body into the proper hepatic artery were administered at intervals of 3-4 weeks. UFT of 300-400 mg/day was orally administered with the infusion. The primary response for hepatic metastatic lesions was observed in one case of CR, 14 cases of PR, 4 cases of NC, and one case of PD. The efficacy for CR and PR was high at 75%. The median disease-free interval was 56 weeks in responders. The 50% survival period was 11.1 months; one-year survival rate, 42.1%; two-year survival rate, 12.3%; the longest survival period was 108 weeks. Mild and transient side effects were recognized in 17 cases (85%): gastrointestinal symptoms, sense of general malaise, fever, leukocytopenia, and elevated BUN. Thus, the results indicated that this combination chemotherapy was effective for liver metastases of gastric cancer.

Background Approximately a quarter of men with metastatic non-seminomatous germ cell tumor (NSGCT) have a residual mass, typically in the retroperitoneum, after chemotherapy. The management of small residual masses (≤1 cm) is controversial, with good outcomes seen with either post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) or surveillance. We sought to review our experience of surveillance and synthesize the cumulative findings with the current literature in the form of a meta-analysis. Patients and methods We searched PubMed, EMBASE and abstracts from ASCO and AUA to identify relevant, English-language studies for the meta-analysis. The DFCI (Dana Farber Cancer Institute) database was constructed from a database of men undergoing cisplatin-based chemotherapy for metastatic NSGCT. The outcomes of interest were the proportion with necrosis, teratoma or active cancer on histology at PC-RPLND (literature) and the total number of relapses, RP-only relapses and overall survival in men undergoing surveillance (literature and DFCI cohort). Results Three of 47 men undergoing post-chemotherapy surveillance at our institution relapsed over a median follow-up of 5.4 years. All three were alive at a median of 4.2 years after relapse. On meta-analysis, the pooled estimates of necrosis, teratoma and active cancer in the 588 men who underwent PC-RPLND were 71, 24 and 4%, respectively. Of the combined 455 men who underwent surveillance, the pooled estimate of the relapse rate was 5%, with an RP-only relapse rate of 3%. Of the 15 men who suffered an RP-only relapse on surveillance, two died of disease. Conclusion Surveillance is a reasonable strategy for men with minimal residual RP disease after chemotherapy and avoids an RPLND in ∼97% of men who are cured with chemotherapy alone. PMID:24276027

Colorectal cancer (CRC) is the third most common cancer worldwide. The mortality from CRC remains very high. The main cause of such a high mortality is a disseminate process with the appearance of distant metastases. In this regard, the treatment of metastatic lesions is recognized as an important trend in modern oncology. The program of study included 176 patients with colorectal cancer after primary tumor removal with the malignant progression-multiple (more than 4) bilobar liver metastases. The research was organized in Samara Regional Oncology Centre from 2001 to 2014. By the treatment method, patients were divided into two groups. Main group got the combined (chemotherapy + radiofrequency ablation (RFA)) treatment ( n  = 98). In control group, only chemotherapy was applied ( n  = 78). One-, two-, and three-year OS were 73.5, 25.1, and 7.2% in the main group and 39.6, 6.3, and 2.1% in the control group. The RFA application allowed us to reach the index of 4-year survival 1.8% in the main group, while we received only 2.1 of 3-year survival in the control group. The OS median reached 18 months in the main group and 11 months in the control group. So, the OS curves in two comparing groups were significantly different according to statistics (log-rank test 3.77, р  = 0.000). The application of RFA in combination with chemotherapy in the treatment of bilobar metastasis colorectal cancer allows to improve the performance of disease-free survival and overall survival significantly, compared with the group of patients who received only chemotherapy.

Background: Locoregional treatment of inflammatory breast cancer (IBC) is crucial because local relapses may be highly symptomatic and are commonly associated with distant metastasis. With a median follow-up of 20 years, we report here the long-term results of a monocentric clinical trial combining primary chemotherapy (CT) with a schedule of anthracycline-based CT and an alternating split-course of radiotherapy (RT Asterisk-Operator CT) without mastectomy. Methods and Materials: From September 1983 to December 1989, 124 women with nonmetastatic IBC (T4d M0) were treated with three cycles of primary AVCMF chemotherapy (anthracycline, vincristine, cyclophosphamide, methotrexate, and 5-fluorouracil) and then an alternating RT Asterisk-Operatormore » CT schedule followed by three cycles of FAC. Hormonal therapy was systematically administered: ovarian irradiation (12 Gy in four fractions) or tamoxifen 20 mg daily. Results: Local control was achieved in 82% of patients. The 10- and 20-year local relapse rates were 26% and 33%, respectively, but only 10% of locally controlled cases were not associated with concurrent distant metastasis. The 10- and 20-year overall survival rates were 39% and 19%, respectively. Severe fibrosis occurred in 54% of patients, grade 3 brachial plexus neuropathy in 4%, grade 2 pneumonitis in 9%. Grade 1, 2 and 3 cardiac toxicity was observed in 3.8%, 3.8% and 1.2% of cases respectively. Conclusions: This combined regimen allowed good long-term local control without surgery. Survival rates were similar to those obtained with conventional regimens (primary chemotherapy, total mastectomy, and adjuvant radiotherapy). Since IBC continues to be an entity with a dismal prognosis, this approach, safely combining preoperative or postoperative radiation therapy and systemic treatments, should be reassessed when suitable targeted agents are available.« less

Introduction The role of surgery in addition to chemotherapy and radiation for stage IIIA non-small cell lung cancer (NSCLC) remains controversial. Since there is limited data on the benefit from surgery in this setting, we evaluated the use of combined modality therapy nationally, and explored the outcomes with and without the addition of surgery. Methods Patient variables and treatment-related outcomes were abstracted for patients with clinical stage IIIA NSCLC from the National Cancer Database. Patients receiving chemotherapy and radiation (CR) were compared to those undergoing chemotherapy, radiation, and surgery in any sequence (CRS). Results Between 1998 and 2010, 61339 patients underwent combined modality treatment for clinical stage IIIA NSCLC. Of these, 51979 (84.7%) received CR while 9360 (15.3%) underwent CRS. Patients in the CRS group were younger, more likely females and Caucasians, had smaller tumors and lower Charlson comorbidity scores. The 30-day surgical mortality was 200/8993 (2.2%). The median overall survival favored the CRS group in both unmatched (32.4 months vs. 15.7 months, p<.001) and matched analysis based on patient characteristics (34.3 months vs. 18.4months, p<.001). Conclusion There is significant heterogeneity in the treatment of stage IIIA NSCLC in the United States. Patients selected for surgery in addition to chemoradiation therapy appear to have better long-term survival. PMID:24722151

Adrenocortical carcinoma (ACC) in childhood is a rare tumor with high fatality rate. Available reports provide event free survival rates ranging between 10 to 50%. Optimal treatment has not yet been established; surgery plays a major role, and the value of adjuvant chemotherapy needs to be evaluated further, especially in children who develop recurrent disease and those with metastases at diagnosis. Optimal therapy of ACC has not been established. Surgery has been curative after complete tumor resection. Children with inoperable, recurrent and metastatic ACC have been treated with O,P'DDD, with response rates ranging from 10 to 60% in different series [7,11-20]. Radiotherapy [21] and other anti-cancer drugs have been used [4-22] but their efficacy has not been established. Combination chemotherapy containing oncovin, cisPlatinum, epipodophyllotoxin and cyclophosphamide (OPEC) produced regression of metastatic ACC in a 5-year-old male [23]. We report one girl with relapsed disseminated ACC who showed good, even if temporary, control of the disease, with disappearance of lung, liver and spleen metastases, and marked reduction of the adrenal mass, following combined chemotherapy according to the "eight-drugs-in-one-day" protocol.

Combinations of 4-aminobenzoic acid competitors and dihydrofolate dehydrogenase inhibitors in the chemotherapy of malaria

Laing, A. B. G.

1974-01-01

Potentiating combinations of 4-aminobenzoic acid (PABA) competitors, such as sulfadoxine, sulfalene, or dapsone, and dihydrofolate dehydrogenasea (1.5.1.4) inhibitors, such as pyrimethamine or proguanil, have been subjected to various trials over the last decade. By and large they have proved to be effective agents against drug-resistant strains of malaria parasites, and with the small doses required they have been free of toxic effects. Parasite resistance to such combinations has seldom occurred but may be associated with cross-resistance to other combinations. These combinations should be reserved for the treatment of chloroquine-resistant infections and for use as adjuvants in organized malaria eradication campaigns. PMID:4613505

Abstract Chemotherapy-induced neutropenia (CIN) is one of the major adverse events that necessitate chemotherapy dose reduction. This study aimed to evaluate the association between grade 4 neutropenia and genetic polymorphisms in breast cancer patients. In this genetic polymorphism association study, peripheral blood samples from 100 consecutive breast cancer outpatients, between August 2012 and September 2014, treated with doxorubicin and cyclophosphamide (AC) combination chemotherapy were genotyped for polymorphisms in adenosine triphosphate-binding cassette subfamily B member 1 (ABCB1), cytochrome P450 (CYP) enzyme-coding genes (CYP2B6 and CYP3A5), glutathione S-transferase (GST), and excision repair cross-complementing 1 (ERCC1). Associations between grade 4 neutropenia and genotypes as well as risk factors were examined using multivariate logistic regression. From 100 patients, 32.0% had grade 4 neutropenia. Multivariate logistic regression analysis revealed that ERCC1 118C > T (odds ratio [OR], 3.43; 95% confidence interval [CI], 1.22–9.69; P = 0.020), CYP2B6∗6 (OR, 4.51; 95% CI, 1.21–16.95; P = 0.025), body mass index (BMI) (OR, 6.94; 95% CI, 1.15–41.67; P = 0.035), and baseline white blood cell (WBC) count (OR, 2.99; 95% CI, 1.06–8.40; P = 0.038) were significant predictors of grade 4 neutropenia. ERCC1 and CYP2B6 gene polymorphisms were associated with the extent of grade 4 neutropenia in patients receiving AC chemotherapy. In addition to previously known risk factors, BMI and WBC counts, ERCC1 and CYP2B6 gene polymorphisms were also identified as independent strong predictors of grade 4 neutropenia. PMID:27858847

Clofarabine, one of the key treatment agents for refractory and relapsed acute lymphoblastic leukemia (ALL), achieves a remission rate of approximately 30% with single-agent clofarabine induction chemotherapy. However, a remission rate of approximately 50% was reported with a combination chemotherapy regimen consisting of clofarabine, etoposide, and cyclophosphamide. We treated two cases with refractory and relapsed ALL with combination chemotherapy including clofarabine; one was an induction failure but the other achieved remission. Both cases developed an infectious complication (NCI-CTCAE grade 3) and body pain with infusion. Prophylactic antibiotic and opioid infusions facilitated avoiding septic shock and pain. Further investigation of such cases is required.

Hormone receptor-positive breast cancers respond favorably to subcutaneous testosterone combined with an aromatase inhibitor. However, the effect of testosterone combined with an aromatase inhibitor on tumor response to chemotherapy was unknown. This study investigated the effect of testosterone-letrozole implants on breast cancer tumor response before and during neoadjuvant chemotherapy. A 51-year-old woman on testosterone replacement therapy was diagnosed with hormone receptor-positive invasive breast cancer. Six weeks before starting neoadjuvant chemotherapy, the patient was treated with subcutaneous testosterone-letrozole implants and instructed to follow a low-glycemic diet. Clinical status was followed. Tumor response to "testosterone-letrozole" and subsequently, "testosterone-letrozole with chemotherapy" was monitored using serial ultrasounds and calculating tumor volume. Response to therapy was determined by change in tumor volume. Cost of therapy was evaluated. There was a 43% reduction in tumor volume 41 days after the insertion of testosterone-letrozole implants, before starting chemotherapy. After the initiation of concurrent chemotherapy, the tumor responded at an increased rate, resulting in a complete pathologic response. Chemotherapy was tolerated. Blood counts and weight remained stable. There were no neurologic or cardiac complications from the chemotherapy. Cost of therapy is reported. Subcutaneous testosterone-letrozole was an effective treatment for this patient's breast cancer and did not interfere with chemotherapy. This novel combination implant has the potential to prevent side effects from chemotherapy, improve quality of life, and warrants further investigation.

93 patients with LABC (T2N1-2M0, T3N0-2M0) at the age from 35 to 75 years were included in the trial. With 2 stage - 60 patients, with the third stage - 33 patients. All patients were randomized into 3 groups: The I control group (n=36) received 4 courses of neoadjuvant chemotherapy according to AC-protocol (doxorubicin 50 mg/m2, cyclophosphan-500 mg/m2 on day 1, repeated every three weeks) followed by radical mastectomy, 4 courses of adjuvant chemotherapy (АС), radiotherapy and hormone therapy if indicated. II investigative group (n=30) received the same CTX but in combination with Arglabin at a dose of 370 mg/m2 for 7 days. III investigative group (n=27) received Arglabin as monotherapy. The clinical efficacy of neoadjuvant chemotherapy according to the scheme of AC and AC + arglabin was the same and significantly exceeded Arlabine monotherapy. There was no statistically significant difference in pathological response in patients of all three groups. Arglabin has very low toxicity and eliminates the toxic effects of standard chemotherapy.

To conduct an economic evaluation of the 70-gene signature used to guide adjuvant chemotherapy decision making both in patients with node-negative breast cancer (NNBC) and in the subgroup of estrogen receptor (ER) -positive patients. We used a mixed approach combining patient-level data from a multicenter validation study of the 70-gene signature (untreated patients) and secondary sources for chemotherapy efficacy, unit costs, and utility values. Three strategies on which to base the decision to administer adjuvant chemotherapy were compared: the 70-gene signature, Adjuvant! Online, and chemotherapy in all patients. In the base-case analysis, costs from the French National Insurance Scheme, life-years (LYs), and quality-adjusted life-years (QALYs) were computed for the three strategies over a 10-year period. Cost-effectiveness acceptability curves using the net monetary benefit were computed, combining bootstrap and probabilistic sensitivity analyses. The mean differences in LYs and QALYs were similar between the three strategies. The 70-gene signature strategy was associated with a higher cost, with a mean difference of €2,037 (range, €1,472 to €2,515) compared with Adjuvant! Online and of €657 (95% CI, -€642 to €3,130) compared with systematic chemotherapy. For a €50,000 per QALY willingness-to-pay threshold, the probability of being the most cost-effective strategy was 92% (76% in ER-positive patients) for the Adjuvant! Online strategy, 6% (4% in ER-positive patients) for the systematic chemotherapy strategy, and 2% (20% in ER-positive patients) for the 70-gene strategy. Optimizing adjuvant chemotherapy decision making based on the 70-gene signature is unlikely to be cost effective in patients with NNBC. © 2014 by American Society of Clinical Oncology.

Olanzapine is effective in chemotherapy-induced nausea and vomiting (CINV). In patients receiving highly emetogenic chemotherapy (HEC), its efficacy was reported as rescue therapy for breakthrough emesis refractory to triplet therapy (palonosetron, aprepitant, and dexamethasone). However, its preventive effects with triplet therapy for CINV are unknown. This study aimed to investigate efficacy and safety of preventive use of olanzapine with triplet therapy for CINV of HEC. This study is a prospective multicenter study conducted by Kansai Clinical Oncology Group. Forty chemo-naïve gynecological cancer patients receiving HEC with cisplatin (≥50 mg/m(2)) were enrolled. Oral olanzapine (5 mg) was administered with triplet therapy a day prior to cisplatin administration and on days 1-5. The primary endpoint was complete response (no vomiting and no rescue) rate for the overall phase (0-120 h post-chemotherapy). Secondary endpoints were complete response rate for acute phase (0-24 h post-chemotherapy) and delayed phase (24-120 h post-chemotherapy) and complete control (no vomiting, no rescue, and no significant nausea) rate and total control (no vomiting, no rescue, and no nausea) rate for each phase. These endpoints were evaluated during the first cycle of chemotherapy. Complete response rates for acute, delayed, and overall phases were 97.5, 95.0, and 92.5 %, respectively. Complete control rates were 92.5, 87.5, and 82.5 %, respectively. Total control rates were 87.5, 67.5, and 67.5 %, respectively. There were no grade 3 or 4 adverse events. Preventive use of olanzapine combined with triplet therapy gives better results than those from previously reported studies of triplet therapy.

A retrospective study was performed to evaluate response rate, time to progression, and toxicity of a bleomycin and cytosine arabinoside (Bleo/Cytarabine) combination protocol for dogs with relapsed lymphoma (LSA). Dogs diagnosed with LSA and previously treated with chemotherapy were included in the study. A total of 20 dogs met the inclusion criteria, and 19 were evaluable for response. Bleomycin was administered subcutaneously on days 1 and 8 and cytosine arabinoside was administered subcutaneously on days 1-5 of a 21-day cycle. The median number of chemotherapy drugs given prior to the administration of Bleo/Cytarabine was 8.5. A total of 23 cycles of Bleo/Cytarabine were administered. The overall response rate was 36.8% (7 of 19 dogs had a partial response). The median time to progression was 15 days. Three dogs developed grade 3 thrombocytopenia and one dog had a grade 4 neutropenia. Bleo/Cytarabine had minor activity when used as a rescue therapy for pretreated LSA patients.

Platinum-based systemic chemotherapy is considered the backbone for management of advanced urothelial carcinomas. However there is a lack of real world data on the use of such chemotherapy regimens, on patient profiles and on management after treatment failure. Fifty-one randomly selected physicians from 4 European countries registered 218 consecutive patients in progression or relapse following a first platinum-based chemotherapy. Patient characteristics, tumor history and treatment regimens, as well as the considerations of physicians on the management of urothelial carcinoma were recorded. A systemic platinum-based regimen had been administered as the initial chemotherapy in 216 patients: 15 in the neoadjuvant setting, 61 in adjuvant therapy conditions, 137 in first-line advanced setting and 3 in other conditions. Of these patients, 76 (35 %) were initially considered as cisplatin-unfit, mainly because of renal impairment (52 patients). After platinum failure, renal impairment was observed in 44 % of patients, ECOG Performance Status ≥ 2 in 17 %, hemoglobinemia < 10 g/dL in 16 %, hepatic metastases in 13 %. 80 % of these patients received further anticancer therapy. Immediately after failure of adjuvant/neoadjuvant chemotherapy, most subsequent anticancer treatments were chemotherapy doublets (35/58), whereas after therapy failure in the advanced setting most patients receiving further anticancer drugs were treated with a single agent (80/114). After first progression to chemotherapy, treatment decisions were mainly driven by Performance Status and prior response to chemotherapy (>30 % patients). The most frequent all-settings second anticancer therapy regimen was vinflunine (70 % of single-agent and 42 % of all subsequent treatments), the main reasons evoked by physicians (>1 out of 4) being survival benefit, safety and phase III evidence. In this daily practice experience, a majority of patients with urothelial carcinoma previously treated with a platinum-based therapy received a second chemotherapy regimen, most often a single agent after an initial chemotherapy in the advanced setting and preferably a cytotoxic combination after a neoadjuvant or adjuvant chemotherapy. Performance Status and prior response to chemotherapy were the main drivers of further treatment decisions.

One hundred consecutive patients with previously untreated advanced squamous cell carcinoma of the head and neck were treated with induction combination chemotherapy followed by definitive surgery and/or radiotherapy, and were evaluated for radiotherapy related toxicity. The induction regimen consisted of cisplatin, bleomycin and methotrexate/leucovorin. Acute toxicity consisted predominantly of mucositis and weight loss, and was mild or moderate by degree in 94% of patients. Six percent of patients experienced severe or life threatening acute toxicities. Two acute toxic deaths were noted in this series, one from a combination of mucositis, weight loss and infection and one from hypoglycemia of unknownmore » origin. Thirty-five percent of patients had radiation treatment interrupted briefly because of acute toxicity. Radiotherapy dose, surgical intervention and age did not have an impact on the presence or degree of acute toxicity. Late toxicities included: hypothyroidism in 32% of patients tested: osteoradionecrosis in 5% of patients, associated primarily with a composite resection (4 of 5 cases); and soft tissue ulcerations in 3%. Taken together, these data indicate that induction combination chemotherapy did not significantly increase the toxicity of subsequent radiotherapy with or without surgery.« less

Discovery and Delivery of Synergistic Chemotherapy Drug Combinations to Tumors

NASA Astrophysics Data System (ADS)

Camacho, Kathryn Militar

Chemotherapy combinations for cancer treatments harbor immense therapeutic potentials which have largely been untapped. Of all diseases, clinical studies of drug combinations are the most prevalent in oncology, yet their effectiveness is disputable, as complete tumor regressions are rare. Our research has been devoted towards developing delivery vehicles for combinations of chemotherapy drugs which elicit significant tumor reduction yet limit toxicity in healthy tissue. Current administration methods assume that chemotherapy combinations at maximum tolerable doses will provide the greatest therapeutic effect -- a presumption which often leads to unprecedented side effects. Contrary to traditional administration, we have found that drug ratios rather than total cumulative doses govern combination therapeutic efficacy. In this thesis, we have developed nanoparticles to incorporate synergistic ratios of chemotherapy combinations which significantly inhibit cancer cell growth at lower doses than would be required for their single drug counterparts. The advantages of multi-drug incorporation in nano-vehicles are many: improved accumulation in tumor tissue via the enhanced permeation and retention effect, limited uptake in healthy tissue, and controlled exposure of tumor tissue to optimal synergistic drug ratios. To exploit these advantages for polychemotherapy delivery, two prominent nanoparticles were investigated: liposomes and polymer-drug conjugates. Liposomes represent the oldest class of nanoparticles, with high drug loading capacities and excellent biocompatibility. Polymer-drug conjugates offer controlled drug incorporations through reaction stoichiometry, and potentially allow for delivery of precise ratios. Here, we show that both vehicles, when armed with synergistic ratios of chemotherapy drugs, significantly inhibit tumor growth in an aggressive mouse breast carcinoma model. Furthermore, versatile drug incorporation methods investigated here can be broadly applied to various agents. Findings from our research can potentially widen the therapeutic window of chemotherapy combinations by emphasizing investigations of optimal drug ratios rather than maximum drug doses and by identifying appropriate nanoparticles for their delivery. Application of these concepts can ultimately help capture the full therapeutic potential of combination regimens.

Magnetic nanoparticle-conjugated polymeric micelles (MNP-PMs) consisting of poly(ethylene glycol)-poly(lactide) (PEG-PLA) and iron oxide nanoparticles were prepared and used as nanocarriers for combined hyperthermia and chemotherapy. Doxorubicin (DOX) was encapsulated in MNP-PMs, and an alternating magnetic field (AMF) resulted in an increase to temperature within a suitable range for inducing hyperthermia and a higher rate of drug release than observed without AMF. In vitro cytotoxicity and hyperthermia experiments were carried out using human lung adenocarcinoma A549 cells. When MNP-PMs encapsulated with an anticancer drug were used to treat A549 cells in combination with hyperthermia under AMF, 78% of the cells were killed by the double effects of heat and the drug, and the combination was more effective than either chemotherapy or hyperthermia treatment alone. Therefore, MNP-PMs encapsulated with an anticancer drug show potential for combined chemotherapy and hyperthermia.Magnetic nanoparticle-conjugated polymeric micelles (MNP-PMs) consisting of poly(ethylene glycol)-poly(lactide) (PEG-PLA) and iron oxide nanoparticles were prepared and used as nanocarriers for combined hyperthermia and chemotherapy.

Purpose: To report outcomes for patients with resected pancreas cancer treated with an adjuvant regimen consisting of gemcitabine-based combination chemotherapy followed by capecitabine and radiation. Patients and Methods: We performed a retrospective review of a series of patients treated at a single institution with a common postoperative adjuvant program. Between January 2002 and August 2006, 43 resected pancreas cancer patients were offered treatment consisting of 4, 21-day cycles of gemcitabine 1 g/m{sup 2} intravenously over 30 min on Days 1 and 8, with either cisplatin 35 mg/m{sup 2} intravenously on Days 1 and 8 or capecitabine 1500 mg/m{sup 2} orallymore » in divided doses on Days 1-14. After completion of combination chemotherapy, patients received a course of radiotherapy (54 Gy) with concurrent capecitabine (1330 mg/m{sup 2} orally in divided doses) day 1 to treatment completion. Results: Forty-one patients were treated. Median progression-free survival for the entire group was 21.7 months (95% confidence interval 13.9-34.5 months), and median overall survival was 45.9 months. In multivariate analysis a postoperative CA 19-9 level of >=180 U/mL predicted relapse and death. Toxicity was mild, with only two hospitalizations during adjuvant therapy. Conclusions: A postoperative adjuvant program using combination chemotherapy with gemcitabine and either cisplatin or capecitabine followed by radiotherapy with capecitabine is tolerable and efficacious and should be considered for Phase III testing in this group of patients.« less

Phase II trial in metastatic urothelial carcinoma using a novel combination chemotherapy regimen consisting of vinblastine, ifosfamide, and gallium nitrate (VIG). Twenty-seven patients were entered onto this phase II study. Dosages were vinblastine 0.11 mg/kg days 1 and 2, ifosfamide 1.2 gm/m2 days 1 through 5 (with mesna), and gallium 300 mg/m2 as a 24-hour infusion days 1 through 5, with calcitriol (1,25-dihydroxycholecalciferol) 0.5 microgram/d orally starting 3 days before each course (except the first) and continuing throughout gallium administration, plus recombinant human granulocyte colony-stimulating factor (rhG-CSF) (filgrastim) 5 micrograms/kg/d days 7 through 16. Courses were repeated every 21 days for a maximum of six cycles. The major toxicity was granulocytopenia. Fifteen patients (55.6%) had grade 3 or 4 granulocytopenia, including eight patients with granulocytopenic fevers. Eleven patients had grade 3 or 4 anemia and four had grade 3 or 4 nephrotoxicity, which was reversible. Other grade 3 to 4 toxicities included hypocalcemia (three patients), thrombocytopenia (two), encephalopathy (one), and temporary blindness (one). There was one treatment-related mortality. Toxicity was more severe in patients older than 70 years and those with prior pelvic irradiation, prior cisplatin adjuvant therapy, or prior nephrectomy. We now decrease VIG by 20% in this patient population. Eighteen patients (67%) achieved an objective response, including 11 (41%) who attained a disease-free status (five with VIG alone and six with subsequent surgery). Median duration of remission was 20 weeks, with five patients still in remission at 22+ to 56+ weeks. VIG combination chemotherapy is very active in patients with metastatic urothelial carcinoma. Toxicity was significant but manageable.

These articles both report the results of multi-institutional, randomized, phase 3 trials for the treatment of patients with localized (T1-3 N0-1 M0) esophageal squamous cell carcinoma (SCC) or esophageal adenocarcinoma. Both studies were initiated and coordinated by the Radiation Therapy Oncology Group (RTOG) but included patients enrolled by other study groups as well. Cooper et al. report late follow-up results for the RTOG 85-01 trial that was conducted between 1986 and 1990. This trial randomized patients to either radiation therapy (RT) alone (RT, 64 Gy in 32 fractions over 6.4 wk, n = 62) or combined RT and chemotherapy (50 Gy in 25 fractions over 5 wk, plus cisplatin 75 mg/m2 i.v. on first day of wk 1, 5, 8, and 11, and continuous infusion fluorouracil (5FU) 1 g/m2 per day on the first 4 days of the same weeks, n = 61). Most (82%) of the patients had SCC. Eight percent of the cohort randomly assigned to combined modality therapy experienced acute life-threatening toxic effects, and an additional 2% died as a direct consequence of treatment. The randomized trial was halted in 1990 when an interim analysis found a highly significant difference in survival favoring the combined therapy group, after which 73 consecutive patients were enrolled into a nonrandomized study offering only the combined therapy regimen. At 5-yr of follow-up, the overall survival rate for the combined therapy group in the randomized study was 26% (95% CI, 15-37%) compared with 0% for RT alone. In the nonrandomized study, the 5-yr overall survival rate was 14% (95% CI, 6-23%). The histopathological type of tumor did not significantly influence survival. Cooper et al. now report that 22% of the randomized combined modality group survived at least 8 yr after treatment, and that there were no deaths caused by esophageal cancer after 5 yr post-treatment. The study reported by Kelsen et al. included 440 patients with esophageal adenocarcinoma (n = 236) or SCC (n = 204) randomized to either preoperative chemotherapy plus esophagectomy or to esophagectomy alone. The chemotherapy regimen consisted of three cycles of preoperative cisplatin and 5FU and two cycles after operation for responding patients. Doses were higher than those used in the RTOG 85-01 trial. Although radiation therapy was not part of the treatment plan, it could be given in some circumstances. There was no significant difference in median survival (14.9 months for chemotherapy plus surgery compared with 16.1 months for surgery alone), and there were also no significant differences in 1-yr, 2-yr, 3-yr, or disease-free survival rates. There were no significant differences in survival between patients with adenocarcinoma and those with SCC. A clinical response to chemotherapy, as assessed by barium contrast radiography, was found in 19% of patients who received chemotherapy. A complete pathological response was found in 2.5% of patients. There was no significant increase in operative complications in the chemotherapy treated group.

Sebaceous carcinoma (SC) is an uncommon neoplasm manifesting itself either in the eyelid or extraocularly in the head and neck area. Surgery is the standard of care. Irradiation is rarely proposed as monotherapy but is frequently administered as an adjuvant regimen following surgical resection. There is no known strategy concerning chemotherapeutic treatment in highly aggressive recurrent – or metastatic – forms of the disease. Our patient presented with an aggressive SC of the scalp recurring after multiple excisions and local radiotherapy. Chemotherapy with 5-fluorouracil, cisplatin and docetaxel was then initiated; 4 cycles were administered, followed by capecitabine maintenance. Shortly after starting chemotherapy, dermal lesions had completely disappeared and radiological response could be seen. The patient experienced an extended period (>20 months) of complete remission. In this report, we show an excellent response of a highly aggressive SC after a combination of chemotherapy as for head and neck cancers. PMID:24748864

Functional hyper-IL-6 from vaccinia virus-colonized tumors triggers platelet formation and helps to alleviate toxicity of mitomycin C enhanced virus therapy

PubMed Central

2012-01-01

Background Combination of oncolytic vaccinia virus therapy with conventional chemotherapy has shown promise for tumor therapy. However, side effects of chemotherapy including thrombocytopenia, still remain problematic. Methods Here, we describe a novel approach to optimize combination therapy of oncolytic virus and chemotherapy utilizing virus-encoding hyper-IL-6, GLV-1h90, to reduce chemotherapy-associated side effects. Results We showed that the hyper-IL-6 cytokine was successfully produced by GLV-1h90 and was functional both in cell culture as well as in tumor-bearing animals, in which the cytokine-producing vaccinia virus strain was well tolerated. When combined with the chemotherapeutic mitomycin C, the anti-tumor effect of the oncolytic virotherapy was significantly enhanced. Moreover, hyper-IL-6 expression greatly reduced the time interval during which the mice suffered from chemotherapy-induced thrombocytopenia. Conclusion Therefore, future clinical application would benefit from careful investigation of additional cytokine treatment to reduce chemotherapy-induced side effects. PMID:22236378

Chemotherapy is assumed to be immunosuppressive; yet to the authors' knowledge, the effects of common chemotherapy protocols on adaptive immune responses in dogs with cancer have not been fully evaluated. Therefore, a study was conducted to evaluate the effects of 2 common chemotherapy protocols on T- and B-cell numbers and humoral immune responses to de novo vaccination in dogs with cancer. Twenty-one dogs with cancer (12 with lymphoma, 9 with osteosarcoma) were enrolled in a prospective study to assess effects of doxorubicin versus multi-drug chemotherapy on adaptive immunity. Numbers of circulating T and B cells were assessed by flow cytometry, and antibody responses to de novo vaccination were assessed before, during, and after chemotherapy. The T- and B-cell numbers before treatment also were compared with those of healthy, age-matched, control dogs. Prior to treatment, dogs with cancer had significantly fewer (P < .05) CD4+ T cells and CD8+ T cells than did healthy dogs. Doxorubicin treatment did not cause a significant decrease in T- or B-cell numbers, whereas treatment with combination chemotherapy caused a significant and persistent decrease in B-cell numbers. Antibody titers after vaccination were not significantly different between control and chemotherapy-treated dogs. These findings suggest that chemotherapy may have less impact on T-cell numbers and ability to mount antibody responses in dogs with cancer than was previously anticipated, though dogs with lymphoma or osteosarcoma appear to be relatively T-cell deficient before initiation of chemotherapy.

Rapid palliation of symptoms with platinum-based chemotherapy plus cetuximab in recurrent oral cancer: a case report

PubMed Central

2010-01-01

Background Symptom control is an important consideration in the choice of treatment for patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). Patients who demonstrate objective tumour responses to platinum-based chemotherapy are more likely to have symptom relief than those who do not have such responses. A phase III trial (EXTREME) showed that adding the epidermal growth factor receptor (EGFR)-targeting IgG1 monoclonal antibody cetuximab to first-line platinum-based chemotherapy significantly prolongs progression-free and overall survival and increases response rate compared with platinum-based chemotherapy alone. We report here the case of a 60-year old female with recurrent squamous cell carcinoma of the gum who had rapid palliation of symptoms and reduction of facial disease mass following treatment with a combination of carboplatin/5-fluorouracil (5-FU) and cetuximab. Case presentation The patient was diagnosed with T4N0 M0 disease of the oral cavity in November 2006 and underwent surgery, with R0 resection, followed by adjuvant radiotherapy and concomitant cisplatin chemotherapy. Around 3 months later, the disease recurred and the patient had severe pain (9/10 on a visual pain scale), marked facial oedema and a palpable facial mass of 89 mm. The patient received 4 21-day cycles of carboplatin (AUC 5), 5-FU (1,000 mg/m2/day for 4 days) and cetuximab (400 mg/m2 initial dose followed by subsequently weekly doses of 250 mg/m2), with continuation of cetuximab monotherapy at the end of this time, and pain relief with topical fentanyl and oral morphine. After 7 days of treatment, pain had reduced to 2/10, with discontinuation of morphine after 4 days, and the facial mass had reduced to 70 mm. After 2 cycles of treatment, the facial mass had decreased to 40 mm. After 3 cycles of treatment, pain and facial oedema had resolved completely and a cervical computed tomography scan showed a marked reduction in tumour mass. Cetuximab monotherapy was continued uninterrupted for 7 months. Conclusion This case illustrates the rapid reduction of tumour mass and disease-associated pain and oedema that can be achieved with a combination of platinum-based chemotherapy and cetuximab in recurrent and/or metastatic SCCHN.

In a series of 46 patients with localized gastric cancer treated at Massachusetts General Hospital, problems with excessive acute or chronic toxicity due to combination treatment with irradiation (XRT) and chemotherapy (CT) were not seen. Forty of the 46 received combined treatment with 2 regimens: (1) irradiation plus concomitant 3 days of 5-FU followed by maintenance 5-FU or combined drugs-26 patients; (2) in the other 14 patients, the sequence of irradiation and chemotherapy was altered. A single course of combined drug chemotherapy was given prior to irradiation and 5 to 6 additional courses were administered after completion of XRT (CT-XRT-CT).more » The drug combination was initially 5-FU-BGNU but this was changed to FAM (5-FU, Adriamycin, Mitomycin C). In this series, there were no cases of septicemia or any deaths related to treatment. A 3 year survival rate of about 20% was achieved for the total group of patients and 43% in the group with resection but at high risk for later failure. Our inability to improve these numbers is undoubtedly a result of dose limitations with external beam irradiation combined with a systemic failure problem. When irradiation is combined with surgical resection of all or a majority of tumor, both survival and local control appear to be better than in the unresected patient group. Only 4 of 29 patients (14%) with curative resection, or resection but residual disease, had later evidence of failure within the irradiation field as opposed to 6 of 9 or 66% in the group with unresectable disease.« less

Intracranial meningiomas are often indolent tumors which typically grow over years to decades. Nonetheless, meningiomas that progress after maximum safe resection and radiation therapy pose a significant therapeutic challenge and effective therapies have yet to be identified. Preclinical studies implicate angiogenesis in the pathophysiology of more aggressive meningiomas, suggesting that anti-angiogenic therapies may be of utility in this setting. We performed a retrospective review of fourteen patients with recurrent meningioma treated at Duke University Medical Center with bevacizumab, a humanized monoclonal antibody against vascular endothelial growth factor, administered either alone or in combination with chemotherapy. Most patients were heavily pre-treated. Progression-free survival at 6 months was 86 % and was comparable regardless of meningioma grade and whether bevacizumab was administered as monotherapy or in combination with chemotherapy. Most toxicities were mild however single patients developed CNS hemorrhage (grade 1) and intestinal perforation (grade 4), respectively. Bevacizumab can be administered safely to patients with meningioma and appears to be associated with encouraging anti-tumor effect when administered as either a single agent or in combination with chemotherapy. Phase II trials investigating bevacizumab in patients with progressive/recurrent meningioma are warranted. PMID:22535433

Chemotherapy-induced peripheral neuropathy (CIPN) is a common toxicity secondary to chemotherapy. Genetic factors may be important in predisposing patients to this adverse effect. We studied 950 primary lung cancer patients, who received platinum or platinum-combination drug chemotherapy and who had DNA available for study. We analyzed epidemiological risk factors in 279 CIPN patients and 456 non-CIPN patients and genetic risk factors in 141 CIPN patients and 259 non-CIPN patients. The risk factors studied included demographic, diagnostic, and treatment data, as well as 174 tag SNPs (single nucleotide polymorphisms) across 43 candidate genes in the glutathione, cell cycle, DNA repair, cell signaling, and apoptosis pathways. Patients who had diabetes mellitus were more likely to have CIPN (p=0.0002). Other epidemiologic risk factors associated with CIPN included number of cycles (p=0.0004) and type of concurrent chemotherapy (p<0.001). SNPs most associated with CIPN were in glutathione peroxidase 7 (GPX7) gene (p values 0.0015 and 0.0028, unadjusted and adjusted) and in ATP-binding cassette sub-family C member 4 (ABCC4) gene (p values 0.037 and 0.006, unadjusted and adjusted). We also found other suggestive associations in methyl-o-guanine-methyl-transferase (MGMT) and glutathione-S-transferase (GST) isoforms. Epidemiological and genetic risk factors associated with CIPN in this cohort, included the type of chemotherapy drug, intensity of chemotherapy treatment, and genes known to be associated with chemotherapy resistance. These findings suggest that differentiating between cytotoxic and neurotoxic mechanisms of chemotherapy drugs is challenging but represents an important step toward individualized therapy and improving quality of life for patients.

ER-negative breast cancer includes most aggressive subtypes of breast cancer such as triple negative (TN) breast cancer. Excluded from hormonal and targeted therapies effectively used for other subtypes of breast cancer, standard chemotherapy is one of the primary treatment options for these patients. However, as ER- patients have shown highly heterogeneous responses to different chemotherapies, it has been difficult to select most beneficial chemotherapy treatments for them. In this study, we have simultaneously developed single drug biomarker models for four standard chemotherapy agents: paclitaxel (T), 5-fluorouracil (F), doxorubicin (A) and cyclophosphamide (C) to predict responses and survival of ER- breast cancer patients treated with combination chemotherapies. We then flexibly combined these individual drug biomarkers for predicting patient outcomes of two independent cohorts of ER- breast cancer patients who were treated with different drug combinations of neoadjuvant chemotherapy. These individual and combined drug biomarker models significantly predicted chemotherapy response for 197 ER- patients in the Hatzis cohort (AUC = 0.637, P  = 0.002) and 69 ER- patients in the Hess cohort (AUC = 0.635, P  = 0.056). The prediction was also significant for the TN subgroup of both cohorts (AUC = 0.60, 0.72, P  = 0.043, 0.009). In survival analysis, our predicted responder patients showed significantly improved survival with a >17 months longer median PFS than the predicted non-responder patients for both ER- and TN subgroups (log-rank test P -value = 0.018 and 0.044). This flexible prediction capability based on single drug biomarkers may allow us to even select new drug combinations most beneficial to individual patients with ER- breast cancer. © 2018 The authors.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) achieve good results in selected patients with peritoneal carcinomatosis. High intra-abdominal pressure could enhance the penetration of chemotherapy drugs. The aim of this study was to compare the effects of high pressure and hyperthermia when used separately and when combined in terms of blood and tissue absorption of oxaliplatin in a swine model of intraperitoneal chemotherapy. Four groups of 5 pigs each underwent laparotomy and open intraperitoneal chemotherapy with oxaliplatin at a constant concentration (150 mg/L) for 30 minutes in normothermia and atmospheric pressure (group 1), or hyperthermia (42°C) and atmospheric pressure (group 2), or normothermia and high pressure (25 cm H2O) (group 3), or hyperthermia and high pressure (group 4). High pressure was achieved thorough a water column over the abdomen. Systemic absorption and abdominal tissue mapping of the penetration of oxaliplatin in each group were studied. Blood concentrations of oxaliplatin were similar in the different groups. Hyperthermia achieved higher concentrations in visceral surfaces (P = 0.0014), but not in parietal surfaces. High pressure enhanced diffusion of the drug in both the visceral and parietal peritoneum (P = 0.0058 and P = 0.0044, respectively). The combination of hyperthermia and high pressure significantly increased the penetration of oxaliplatin and achieved the highest tissue concentrations (10.39 mg/kg vs 5.48 mg/kg; P = 0.00001 in the visceral peritoneum, and 66.16 mg/kg vs 35.62 mg/kg; P = 0.0003 in the parietal peritoneum). Open high-pressure HIPEC with oxaliplatin is feasible in the pig. Hyperthermia enhances diffusion in the visceral peritoneum, whereas high pressure is effective in the visceral and parietal peritoneum. The combination of the two achieves the highest tissue concentrations of oxaliplatin.

The aim of this study was to evaluate the feasibility of using diffusion-weighted MRI to monitor the early response of pancreatic cancers to radiofrequency heat (RFH)-enhanced chemotherapy. Human pancreatic carcinoma cells (PANC-1) in different groups and 24 mice with pancreatic cancer xenografts in four groups were treated with phosphate-buffered saline (PBS) as a control, RFH at 42 °C, gemcitabine and gemcitabine plus RFH at 42 °C. One day before and 1, 7 and 14 days after treatment, diffusion-weighted MRI and T2 -weighted imaging were applied to monitor the apparent diffusion coefficients (ADCs) of tumors and tumor growth. MRI findings were correlated with the results of tumor apoptosis analysis. In the in vitro experiments, the quantitative viability assay showed lower relative cell viabilities for treatment with gemcitabine plus RFH at 42 °C relative to treatment with RFH only and gemcitabine only (37 ± 5% versus 65 ± 4% and 58 ± 8%, respectively, p < 0.05). In the in vivo experiments, the combination therapy resulted in smaller relative tumor volumes than RFH only and chemotherapy only (0.82 ± 0.17 versus 2.23 ± 0.90 and 1.64 ± 0.44, respectively, p = 0.003). In vivo, 14-T MRI demonstrated a remarkable decrease in ADCs at day 1 and increased ADCs at days 7 and 14 in the combination therapy group. The apoptosis index in the combination therapy group was significantly higher than those in the chemotherapy-only, RFH-only and PBS treatment groups (37 ± 6% versus 20 ± 5%, 8 ± 2% and 3 ± 1%, respectively, p < 0.05). This study confirms that it is feasible to use MRI to monitor RFH-enhanced chemotherapy in pancreatic cancers, which may present new options for the efficient treatment of pancreatic malignancies using MRI/RFH-integrated local chemotherapy.

To evaluate the activity and toxicity of the combination of capecitabine and cisplatin (CapCisp) in anthracycline- and taxane-pretreated HER-2 negative metastatic breast carcinoma (MBC) female patients. Patients with HER-2 negative MBC pretreated with anthracycline and taxane and who were then treated with CapCisp combination were retrospectively evaluated. All patients received Cap 1000 mg/m(2) on days 1-14, and Cisp 60 mg/m(2) on day 1, repeated every 3 weeks. In case of disease control without severe toxicity, single agent Cap was continued until progression or unacceptable toxicities after Cisp cessation. Sixty-four MBC patients with median age 43 years (range 20-66) were included the study. Infiltrative ductal carcinoma prevailed (85.9%). Ten percent of the patients had grade I, 42% grade II, and 48.0% grade III tumors. Estrogen receptor (ER) and progesterone receptor (PR) were positive in 48.4 and 51.6% of the patients, respectively. Twenty-eight percent of the patients had triple negative tumors. Almost the entire patient group had this regimen as a third-line treatment. The median combination chemotherapy cycles were 6 (range 2-8). Twenty-seven non-progressive patients continued treatment with single-agent Cap. Median single-agent Cap cycles after the combination chemotherapy were 4 (range 1-38). Disease control rate was 81.3% (complete response 6.3%; partial response 48.4%, stable disease 26.6%, progressive disease 18.8%). Median follow-up time was 10.6 months. Median time to disease progression was 7 months, median overall survival (OS) was 17 months (95% CI, 6.9-16.1) measured from the start of CapCisp chemotherapy. There were no treatment-related deaths. The most frequent grade 3-4 toxicities were neutropenia (8.1%), nausea - vomiting (7.8%) and thrombocytopenia (6.3%). CapCisp doublet has an encouraging antitumor activity with acceptable and manageable toxicity in anthracycline- and taxane-pretreated HER-2 negative metastatic breast carcinoma patients.

Immediate prosthetic breast reconstruction produces a satisfactory aesthetic result with high levels of patient satisfaction. However, with the broader indication for post-mastectomy adjuvant radiation, many patients are advised against immediate breast reconstruction because of concerns of implant loss and infection particularly as most patients also require chemotherapy. This retrospective cohort study examines outcomes for patients who underwent immediate two-stage prosthetic breast reconstruction after mastectomy with or without adjuvant chemotherapy or radiotherapy (RT). Between 1998 and 2010, 452 patients undergoing two-stage prosthetic immediate breast reconstruction involving a total of 562 breasts were included in this study. Stage one was defined as insertion of the temporary expander and stage two insertion of the final silicone implant. Post-operative adjuvant radiotherapy was recommended with tissue expander in-situ for 114 patients. Complications, including loss of prosthesis, seroma and infection were recorded and analysed. Cosmetic result was assessed using a 4-point scale. Post-operative prosthesis loss was 2.7%, 5.3% for patients undergoing adjuvant chemotherapy increasing to 11.3% for patients receiving chemotherapy+RT. Chemotherapy and radiotherapy independently were the main, statistically significant, risk factors for expander or implant loss; IRR: 13.85 (p=0.012) and 2.23 (p=0.027), respectively. Prosthesis loss for patients undergoing combination chemotherapy+RT was also significant; IRR: 4.791 (p<0.001). These findings serve to better inform patients on risk in weighing treatment options. Post-mastectomy radiation doubles the risk of prosthesis loss over and above adjuvant chemotherapy but is an acceptable option following immediate prosthetic breast reconstruction in a multidisciplinary setting.

The purpose was to evaluate the feasibility and toxicity of [sup 252]Cf neutron brachytherapy combined with hyperaccelerated chemoradiotherapy for Stage III and IV cervical cancers. Eleven patients with advanced Stage IIIB-IVA cervical cancers were treated with [sup 252]Cf neutron brachytherapy in an up-front schedule followed by cisplatin (CDDP; 50 mg/m[sup 2]) chemotherapy and hyperfractionated accelerated (1.2 Gy bid) radiotherapy given concurrently with intravenous infusion of 5-Fluorouracil (5-FU) (1000 mg/m[sup 2]/day [times] 4 days) in weeks 1 and 4 with conventional radiation (weeks 2, 3, 5, and 6). Total dose at a paracervical point A isodose surface was 80-85 Gy-eq bymore » external and intracavitary therapy and 60 Gy at the pelvic sidewalls. Patients tolerated the protocol well. There was 91% compliance with the chemotherapy and full compliance with the [sup 252]Cf brachytherapy and the external beam radiotherapy. There were no problems with acute chemo or radiation toxicity. One patient developed a rectovaginal fistula (Grade 3-4 RTOG criteria) but no other patients developed significant late cystitis, proctitis or enteritis. There was complete response (CR) observed in all cases. With mean follow-up to 26 months, local control has been achieved with 90% actuarial 3-year survival with no evidence of disease (NED). [sup 252]Cf neutrons can be combined with cisplatin and 5-FU infusion chemotherapy plus hyperaccelerated chemoradiotherapy without unusual side effects or toxicity and with a high local response and tumor control rate. Further study of [sup 252]Cf neutron-chemoradiotherapy for advanced and bulky cervical cancer are indicated. The authors found chemotherapy was more effective with the improved local tumor control. 18 refs., 2 tabs.« less

The combination therapy has exhibited important potential for the treatment of cancers, especially for drug-resistant cancers. In this report, bi-functional nanoprobes based on doxorubicin (DOX)-loaded NaYF4:Yb/Tm-TiO2 inorganic photosensitizers (FA-NPs-DOX) were synthesized for in vivo near infrared (NIR)-triggered inorganic photodynamic therapy (PDT) and enhanced chemotherapy to overcome the multidrug resistance (MDR) in breast cancers. Using the up-conversion luminescence (UCL) performance of NaYF4:Yb/Tm converting near-infrared (NIR) into ultraviolent (UV) lights, reactive oxygen species (ROS) were triggered from TiO2 inorganic photosensitizers for PDT under the irradiation of a 980 nm laser, by which the deep-penetration and low photo-damage could be reached. Moreover, nanocarrier delivery and folic acid (FA) targeting promoted the cellular uptake, and accelerated the release of DOX in drug-sensitive MCF-7 and resistant MCF-7/ADR cells. The toxicity assessment in vitro and in vivo revealed the good biocompatibility of the as-prepared FA-NPs-DOX nanocomposites. By the combination of enhanced chemotherapy and NIR-triggered inorganic PDT, the viability of MCF-7/ADR cells could decrease by 53.5%, and the inhibition rate of MCF-7/ADR tumors could increase up to 90.33%, compared with free DOX. Therefore, the MDR of breast cancers could be obviously overcome by enhanced chemotherapy and NIR-triggered inorganic PDT of FA-NPs-DOX nanocomposites under the excitation of a 980 nm laser.

Temozolomide (TMZ) is the most frequent adjuvant chemotherapy drug in gliomas. PDL1 expresses on various tumors, including gliomas, and anti-PD-1 antibodies have been approved for treating some tumors by FDA. This study was to evaluate the therapeutical potential of combined TMZ with anti-PD-1 antibody therapy for mouse orthotopic glioma model. We performed C57BL/6 mouse orthotopic glioma model by stereotactic intracranial implantation of glioma cell line GL261, mice were randomly divided into four groups: (1) control group; (2) TMZ group; (3) anti-PD-1 antibody group; (4) TMZ combined with anti-PD-1 antibody group. Then the volume or size of tumor was assessed by 7.0 T MRI and immunohistochemistry, and the number of CD4 and CD8 infiltrating cells in brain tumor and spleen was evaluated by immunohistochemistry. Western blot was used to evaluate the expression of PDL1. Furthermore, Overall survival of each group mice was also evaluated. Overall survival was significantly improved in combined group compared to other groups (χ2 = 32.043, p < 0.01). The volume or size of tumor was significantly decreased in combined group compared with other groups (F = 42.771, P < 0.01). And the number of CD4 and CD8 infiltrating cells in brain tumor was also obviously increased in combined group (CD4 F = 45.67, P < 0.01; CD8 F = 53.75, P < 0.01). Anti-PD1 antibody combined with TMZ therapy for orthotopic mouse glioma model could significantly improve the survival time of tumor-bear mice. Thus, this study provides the effective preclinical evidence for support clinical chemotherapy combined with immunotherapy for glioma patients. Copyright © 2018 Elsevier Inc. All rights reserved.

Antrodia cinnamomea (AC) is a popular medicinal mushroom in Taiwan that has been widely used for treatment of various cancers. Few clinical studies have reported its application and efficiency in therapeutic chemotherapy strategies. We performed a double-blind, randomized clinical study to investigate whether AC given for 30 days had acceptable safety and efficacy in advanced cancer patients receiving chemotherapy. Patients with advanced and/or metastatic adenocarcinoma, performance status (PS) 0-2, and adequate organ function who had previously been treated with standard chemotherapy were randomly assigned to receive routine chemotherapy regimens with AC (20 ml twice daily) orally for 30 days or placebo. The primary endpoint was 6-month overall survival (OS); the secondary endpoints were disease control rate (DCR), quality of life (QoL), adverse event (AE), and biochemical features within 30 days of treatment. From August 2010 to July 2012, 37 subjects with gastric, lung, liver, breast, and colorectal cancer (17 in the AC group, 20 in the placebo group) were enrolled in the study. Disease progression was the primary cause of death in 4 (33.3 %) AC and 8 (66.7 %) placebo recipients. Mean OSs were 5.4 months for the AC group and 5.0 months for the placebo group (p = 0.340), and the DCRs were 41.2 and 55 %, respectively (p = 0.33). Most hematologic, liver, or kidney functions did not differ significantly between the two groups, but platelet counts were lower in the AC group than in the placebo group (p = 0.02). QoL assessments were similar in the two groups, except that the AC group showed significant improvements in quality of sleep (p = 0.04). Although we found a lower mortality rate and longer mean OS in the AC group than in the control group, A. cinnamomea combined with chemotherapy was not shown to improve the outcome of advanced cancer patients, possibly due to the small sample size. In fact, the combination may present a potential risk of lowered platelet counts. Adequately powered clinical trials will be necessary to address this question. ClinicalTrials.gov NCT01287286 .

Rectal cancer. Treatment advances that reduce recurrence rates and lengthen survival.

The risk of malignant disease arising in rectal mucosa is high. Surgery is the most effective form of treatment but results in cure in only 50% of patients. Adjuvant preoperative radiation therapy reduces the likelihood of local recurrence but does not improve survival rates. Fluorouracil is the most effective agent for adjuvant chemotherapy and slightly improves survival when given after surgery. Combining radiation therapy with chemotherapy appears to have a synergistic effect, and recent studies show that providing this combination after surgery improves survival. Future trends in the treatment of rectal cancer are expected to include expanded use of local excision to preserve anal sphincter function, preoperative use of a combination of radiation therapy and chemotherapy, perioperative use of chemotherapy combined with immunostimulating therapy, and use of tumor antibodies for diagnostic and therapeutic purposes.

Duodenal bulb adenocarcinoma is an extremely rare malignancy in the alimentary tract which has a low incidence rate and nonspecific symptoms. It is difficult to diagnose early, and the misdiagnosis rate is high. CT, MRI, upper gastrointestinal endoscopy, and other advanced imaging modalities should be combined to make a comprehensive evaluation. The diagnostic confirmation of this tumor type mainly depends on the pathological examination. The combination of surgery with other treatment modalities is effective. A review of reports on duodenal bulb adenocarcinoma with chemotherapy revealed 6 cases since 1990. However, there are few reports on neoadjuvant chemotherapy for the disease. In this report, preoperative S-1 in combination with oxaliplatin neoadjuvant chemotherapy achieved a complete pathological response in the treatment of duodenal bulb adenocarcinoma. Neoadjuvant chemotherapy shows a better clinical efficacy in the treatment of duodenal bulb adenocarcinoma, but its value needs to be further verified. © 2017 S. Karger AG, Basel.

Antiemetic therapy for non-anthracycline and cyclophosphamide moderately emetogenic chemotherapy.

Inui, Naoki

2017-05-01

Although antiemetic management in cancer therapy has improved, chemotherapy-induced nausea and vomiting remain common and troubling adverse events. Chemotherapeutic agents are classified based on their emetogenic effects, and appropriate antiemetics are recommended according to this categorization. Chemotherapy categorized as moderately emetogenic is associated with a wide spectrum of emetic risks. Combined anthracycline and cyclophosphamide regimens have been recently reclassified as highly emetogenic chemotherapy regimen. This review focuses on antiemetic pharmacotherapy in patients receiving non-anthracycline and cyclophosphamide-based moderately emetogenic chemotherapy regimens. Combination therapy with a 5-hydroxytryptamine-3 receptor agonist, preferably palonosetron, and dexamethasone is the standard therapy in moderately emetogenic chemotherapy, although triple therapy with add-on neurokinin-1 receptor antagonist is used as an alternative treatment strategy. Among moderately emetogenic chemotherapy regimens, carboplatin-containing chemotherapy has considerable emetic potential, particularly during the delayed phase. However, the additional of a neurokinin-1 receptor antagonist to the standard antiemetic therapy prevents carboplatin-induced nausea and vomiting. For regimens including oxaliplatin, the benefit of adding neurokinin-1 receptor antagonist requires further clarification.

To identify molecular alterations in prostate cancers associating with relapse following neoadjuvant chemotherapy and radical prostatectomy patients with high-risk localized prostate cancer were enrolled into a phase I-II clinical trial of neoadjuvant chemotherapy with docetaxel and mitoxantrone followed by prostatectomy. Pre-treatment prostate tissue was acquired by needle biopsy and post-treatment tissue was acquired by prostatectomy. Prostate cancer gene expression measurements were determined in 31 patients who completed 4 cycles of neoadjuvant chemotherapy. We identified 141 genes with significant transcript level alterations following chemotherapy that associated with subsequent biochemical relapse. This group included the transcript encoding monoamine oxidase A (MAOA). In vitro, cytotoxic chemotherapy induced the expression of MAOA and elevated MAOA levels enhanced cell survival following docetaxel exposure. MAOA activity increased the levels of reactive oxygen species and increased the expression and nuclear translocation of HIF1α. The suppression of MAOA activity using the irreversible inhibitor clorgyline augmented the apoptotic responses induced by docetaxel. In summary, we determined that the expression of MAOA is induced by exposure to cytotoxic chemotherapy, increases HIF1α, and contributes to docetaxel resistance. As MAOA inhibitors have been approved for human use, regimens combining MAOA inhibitors with docetaxel may improve clinical outcomes. PMID:25198178

The patient was a 68-year-old man who complained of hoarseness and dyspnea. Upper gastrointestinal endoscopy revealed a type 3 tumor located in the middle thoracic esophagus at 30 cm from the incisor tooth that involved one-fourth of the circumference of the esophagus. Histopathological examination revealed moderately differentiated squamous cell carcinoma. Chest computed tomography( CT) revealed severe tracheal stenosis due to compression by a metastatic lymph node along the left recurrent laryngeal nerve. The patient was diagnosed as having cT4( 106recL-trachea), N2( 101L, 106recL, 106recR), M0, Stage IVa unresectable esophageal carcinoma. After insertion of a tracheal stent tube( spiral Z stent: diameter, 18 mm; length, 80 mm) to improve dyspnea, combination chemotherapy with 5-fluorouracil( 5-FU) plus nedaplatin was administered. Subsequent CT and endoscopy showed that the main tumor and the metastatic lymph node had significantly reduced in size and that complete response (CR) had been achieved. Thirty months after the initial treatment, the patient showed no sign of disease recurrence, after completion of 19 cycles of chemotherapy. The patient did not experience any severe adverse events. We report a case of a patient with locally advanced squamous cell carcinoma of the esophagus successfully treated with 5-FU/nedaplatin combination chemotherapy following tracheal stent tube placement.

Although neuroendocrine tumors (NETs) are slow growing, they are frequently metastatic at the time of discovery and no longer amenable to curative surgery, emphasizing the need for the development of other treatments. In this study, multifunctional upconversion nanoparticle (UCNP)-based theranostic micelles are developed for NET-targeted and near-infrared (NIR)-controlled combination chemotherapy and photodynamic therapy (PDT), and bioimaging. The theranostic micelle is formed by individual UCNP functionalized with light-sensitive amphiphilic block copolymers poly(4,5-dimethoxy-2-nitrobenzyl methacrylate)-polyethylene glycol (PNBMA-PEG) and Rose Bengal (RB) photosensitizers. A hydrophobic anticancer drug, AB3, is loaded into the micelles. The NIR-activated UCNPs emit multiple luminescence bands, including UV, 540 nm, and 650 nm. The UV peaks overlap with the absorption peak of photocleavable hydrophobic PNBMA segments, triggering a rapid drug release due to the NIR-induced hydrophobic-to-hydrophilic transition of the micelle core and thus enabling NIR-controlled chemotherapy. RB molecules are activated via luminescence resonance energy transfer to generate 1O2 for NIR-induced PDT. Meanwhile, the 650 nm emission allows for efficient fluorescence imaging. KE108, a true pansomatostatin nonapeptide, as an NET-targeting ligand, drastically increases the tumoral uptake of the micelles. Intravenously injected AB3-loaded UCNP-based micelles conjugated with RB and KE108—enabling NET-targeted combination chemotherapy and PDT—induce the best antitumor efficacy. PMID:28989337

Cisplatin-based induction chemotherapy has been extensively tested in nasopharyngeal carcinoma for the improvement of local and systemic control and survival of this disease. In this study, we report the results of the treatment with induction chemotherapy in 40 patients with locally advanced carcinoma of the nasopharynx (LANPC) with four courses of cisplatin (P) 25 mg/m2 per day and 5-fluorouracil (F) 1000 mg/m2 per day both in a 4-days continuous infusion, with or without leucovorin (L) 250 mg/m2 per day in 2-hour infusion at the beginning of daily administration of PF, followed by sequential radiotherapy. All except one were in stage IV. The overall response after induction chemotherapy was 93%, with 55% CR and 38% PR. Definitive overall response after radiotherapy was 98%, with 80% CR and 18% PR. At a maximum follow up of 11 years, the overall survival rate is 55%. Induction chemotherapy with continuous infusion of PF with or without leucovorin followed by radiotherapy is a highly active regimen for the treatment of locally advanced nasopharyngeal carcinoma with response and survival rates comparable to other combinations of sequential or simultaneous chemotherapy and radiotherapy.

Antiangiogenic agents (AA) are cytostatic, and their utility in cancer chemotherapy lies in their combination with cytotoxic chemotherapeutic agents. Clinical combinations of vascular endothelial growth factor receptor-2 (VEGFR2) inhibitors with antitubulin agents have been particularly successful. We have discovered a novel, potentially important analogue, that combines potent VEGFR2 inhibitory activity (comparable to that of sunitinib) with potent antitubulin activity (comparable to that of combretastatin A-4 (CA)) in a single molecule, with GI50 values of 10(-7) M across the entire NCI 60 tumor cell panel. It potently inhibited tubulin assembly and circumvented the most clinically relevant tumor resistance mechanisms (P-glycoprotein and β-III tubulin expression) to antimicrotubule agents. The compound is freely water-soluble as its HCl salt and afforded excellent antitumor activity in vivo, superior to docetaxel, sunitinib, or Temozolomide, without any toxicity.

Recent studies show direct evidence for quiescence slow-cycling cells playing a role in cancer stem cells. There exists an urgent need to isolate and better characterize these slow-cycling cells. In this study, we developed a new model to enrich slow-cycling tumor cells using cell-cycle inducer combined with cell cycle-dependent chemotherapy in vitro and in vivo . Our results show that Short-term exposure of colorectal cancer cells to chemotherapy combined with cell-cycle inducer enriches for a cell-cycle quiescent tumor cell population. Specifically, these slow-cycling tumor cells exhibit increased chemotherapy resistance in vitro and tumorigenicity in vivo . Notably, these cells are stem-cell like and participate in metastatic dormancy. Further exploration indicates that slow-cycling colorectal cancer cells in our model are less sensitive to cytokine-induced-killer cell mediated cytotoxic killing in vivo and in vitro . Collectively, our cell cycle inducer combined chemotherapy exposure model enriches for a slow-cycling, dormant, chemo-resistant tumor cell sub-population that are resistant to cytokine induced killer cell based immunotherapy. Studying unique signaling pathways in dormant tumor cells enriched by cell cycle inducer combined chemotherapy treatment is expected to identify novel therapeutic targets for preventing tumor recurrence.

Background: Although there are reports that metronomic cyclophosphamide (CTX) can be immune stimulating, the impact of its combination with anti-CTLA-4 immunotherapy for the treatment of cancer remains to be evaluated. Methods: Murine EMT-6/P breast cancer, or its cisplatin or CTX-resistant variants, or CT-26 colon, were implanted into Balb/c mice. Established tumours were monitored for relative growth following treatment with anti-CTLA-4 antibody alone or in combination with; (a) metronomic CTX (ldCTX; 20 mg kg−1 day−1), b) bolus (150 mg kg−1) plus ldCTX, or (c) sequential treatment with gemcitabine (160 mg kg−1 every 3 days). Results: EMT-6/P tumours responded to anti-CTLA-4 therapy, but this response was less effective when combined with bolus plus ldCTX. Anti-CTLA-4 could be effectively combined with either ldCTX (without a bolus), or with regimens of either sequential or concomitant gemcitabine, including in orthotopic EMT-6 tumours, and independently of the schedule of drug administration. Tumour responses were confirmed with CT-26 tumours but were less pronounced in drug-resistant EMT-6/CTX or EMT-6/DDP tumour models than in the parent tumour. A number of tumour bearing mice developed spontaneous metastases under continuous therapy. The majority of cured mice rejected tumour re-challenges. Conclusions: Metronomic CTX can be combined with anti-CTLA-4 therapy, but this therapy is impaired by concomitant bolus CTX. Sequential therapy of anti-CTLA-4 followed by gemcitabine is effective in chemotherapy-naive tumours, although tumour relapses can occur, in some cases accompanied by the development of spontaneous metastases.

Chemotherapy-induced nausea and vomiting remain common, distressing side effects of chemotherapy. It has been reported that acupressure prevents chemotherapy-induced nausea in adults, but it has not been well studied in children. In this multicenter, prospective, randomized, single-blind, sham-controlled trial, the authors compared acute-phase nausea severity in patients ages 4 to 18 years who were receiving highly emetic chemotherapy using standard antiemetic agents combined with acupressure wrist bands, the most common type of acupressure, versus sham bands. Patients wore acupressure or sham bands continuously on each day of chemotherapy and for up to 7 days afterward. Chemotherapy-induced nausea severity in the delayed phase and chemotherapy-induced vomiting control in the acute and delayed phases also were compared. Of the 187 patients randomized, 165 contributed nausea severity assessments during the acute phase. Acupressure bands did not reduce the severity of chemotherapy-induced nausea in the acute phase (odds ratio [OR], 1.33; 95% confidence limits, 0.89-2.00, in which an OR <1.00 favored acupressure) or in the delayed phase (OR, 1.23; 95% CL, 0.75-2.01). Furthermore, acupressure bands did not improve daily vomiting control during the acute phase (OR, 1.57; 95% CL, 0.95-2.59) or the delayed phase (OR, 0.84; 95% CL, 0.45-1.58). No serious adverse events were reported. Acupressure bands were safe but did not improve chemotherapy-induced nausea or vomiting in pediatric patients who were receiving highly emetic chemotherapy.

Molecularly targeted and immunotherapies have improved the care of patients with lung cancers. These successes have rallied calls to replace or avoid chemotherapy. Yet, even in this era of precision medicine and exciting advances, cytotoxic chemotherapies remain an essential component of lung cancer treatment. In the setting of locoregional disease, chemotherapy is the only systemic therapy thus far proven to enhance curability when combined with surgery or radiation. In the metastatic setting, chemotherapy can improve the length and quality of life in many patients. Chemotherapy remains the mainstay of care for individuals whose cancers with oncogenic drivers have acquired resistance to targeted agents. Chemotherapy also has the potential to modulate the immune system to enhance the effectiveness of immune checkpoint inhibitors. In this context, chemotherapy should be framed as a critical component of the armamentarium available for optimizing cancer care rather than an unfortunate anachronism. We examine the role of chemotherapy with precision medicine in the current care of patients with lung cancers, as well as opportunities for future integration in combinations with targeted agents, angiogenesis inhibitors, immunotherapies, and antibody drug conjugates.

Combination chemotherapy is widely exploited for enhanced cancer treatment in clinic. However, the traditional cocktail administration of combination regimens often suffers from varying pharmacokinetics among different drugs. The emergence of nanotechnology offers an unparalleled opportunity for developing advanced combination drug delivery strategies with the ability to encapsulate various drugs simultaneously and unify the pharmacokinetics of each drug. This review surveys the most recent advances in combination delivery of multiple small molecule chemotherapeutics using nanocarriers. The mechanisms underlying combination chemotherapy, including the synergistic, additive and potentiation effects, are also discussed with typical examples. We further highlight the sequential and site-specific co-delivery strategies, which provide new guidelines for development of programmable combination drug delivery systems. Clinical outlook and challenges are also discussed in the end. PMID:26546751

The objective of the present study was to investigate the survival outcome and prognostic factors of metastatic urothelial carcinoma patients treated with second-line systemic chemotherapy in real-world clinical practice. Overall, 114 patients with metastatic urothelial carcinoma undergoing second-line systemic chemotherapy were included in this retrospective analysis. The dominant second-line chemotherapy was a paclitaxel-based combination regimen (60%, 68/114). We assessed the progression-free survival and overall survival times using the Kaplan-Meier method. The Cox proportional hazards model was applied to identify the factors affecting overall survival. The median progression-free survival and overall survival times were 4 and 9 months, respectively. In the multivariate analysis, an Eastern Cooperative Oncology Group performance status score greater than 0 at presentation, C-reactive protein level ≧1 mg/dl and poor response to prior chemotherapy were adverse prognostic indicators. Patients with 0, 1, 2 and 3 of those risk factors had a median overall survival of 17, 12, 7 and 3 months, respectively. The Eastern Cooperative Oncology Group performance status at presentation, C-reactive protein level and response to prior chemotherapy were prognostic factors for metastatic urothelial carcinoma patients undergoing second-line chemotherapy. In the future, this information might help guide the choice of salvage treatment, such as second-line chemotherapy or immune checkpoint inhibitors, after the failure of first-line chemotherapy.

The combination of necitumumab with gemcitabine-cisplatin significantly improved overall survival (OS) in patients with stage IV squamous non-small-cell lung cancer (NSCLC), in the phase III SQUamous NSCLC treatment with the Inhibitor of EGF REceptor (SQUIRE) trial. Paclitaxel-carboplatin was selected as an alternative standard of care in the current phase II study. Patients were randomized (stratified according to Eastern Cooperative Oncology Group performance status and sex) 2:1 to ≤ six 3-week cycles (Q3W) of paclitaxel and carboplatin with or without necitumumab. Chemotherapy was paclitaxel 200 mg/m 2 on day 1 Q3W and carboplatin area under the curve 6 on day 1 Q3W. Necitumumab 800 mg, on days 1 and 8, was continued until disease progression or intolerable toxicity occurred. The primary end point was objective response rate (ORR) on the basis of Response Evaluation Criteria In Solid Tumors version 1.1. One hundred sixty-seven patients were randomized to the necitumumab-containing arm (n = 110) or the chemotherapy-only arm (n = 57). The combination of necitumumab with chemotherapy resulted in an ORR of 48.9% versus 40.0%. Median progression-free survival and OS were 5.4 versus 5.6 months (hazard ratio [HR], 1.0) and 13.2 versus 11.2 months (HR, 0.83; P = .379) in each treatment arm, respectively. Disease control rate was 87.2% versus 84.0%. Grade ≥ 3 adverse events typically associated with epidermal growth factor receptor (EGFR) monoclonal antibodies showing a > 2% increase were hypomagnesemia (5.7% vs. 0) and rash (2.8% vs. 0). Any Grade thromboembolic events occurred in < 4% of patients in either arm. The results of our study support previously reported results that the combination of necitumumab with chemotherapy improves survival in patients with advanced squamous NSCLC and shows a safety profile consistent with that of EGFR monoclonal antibodies.

We measure tissue blood flow markers in breast tumors during neoadjuvant chemotherapy and investigate their correlation to pathologic complete response in a pilot longitudinal patient study (n  =  4). Tumor blood flow is quantified optically by diffuse correlation spectroscopy (DCS), and tissue optical properties, blood oxygen saturation, and total hemoglobin concentration are derived from concurrent diffuse optical spectroscopic imaging (DOSI). The study represents the first longitudinal DCS measurement of neoadjuvant chemotherapy in humans over the entire course of treatment; it therefore offers a first correlation between DCS flow indices and pathologic complete response. The use of absolute optical properties measured by DOSI facilitates significant improvement of DCS blood flow calculation, which typically assumes optical properties based on literature values. Additionally, the combination of the DCS blood flow index and the tissue oxygen saturation from DOSI permits investigation of tissue oxygen metabolism. Pilot results from four patients suggest that lower blood flow in the lesion-bearing breast is correlated with pathologic complete response. Both absolute lesion blood flow and lesion flow relative to the contralateral breast exhibit potential for characterization of pathological response. This initial demonstration of the combined optical approach for chemotherapy monitoring provides incentive for more comprehensive studies in the future and can help power those investigations.

Therapeutic potential of TAS-102 in the treatment of gastrointestinal malignancies

PubMed Central

Peters, Godefridus J.

2015-01-01

Fluoropyrimidines form the mainstay in treatment of gastrointestinal malignancies. For decades 5-fluorouracil (5FU), was the major fluoropyrimidine. Currently it is usually given in a combination with leucovorin and oxaliplatin, i.e. FOLFOX, or irinotecan, i.e. FOLFIRI, or all three, i.e. FOLFIRINOX, but gradually it has been replaced by oral fluoropyrimidine prodrug formulations, such as tegafur-uracil and S-1 (both contain ftorafur), and capecitabine (Xeloda®). Novel drugs such as the antivascular endothelial growth factor antibody, bevacizumab, and the anti-epidermal growth factor receptor antibody, cetuximab, are often combined with one of these treatment options. However, when resistance emerged, no alternatives were available. TAS-102, a combination of trifluorothymidine and the thymidine phosphorylase inhibitor TPI in a 1:0.5 ratio, is a novel oral formulation, which is active in 5FU-resistant models, both in vitro and in xenograft models. In addition to inhibition of thymidylate synthase, the major mechanism of action of classical fluoropyrimidines, TAS-102’s major mechanism of action is incorporation into DNA, thereby causing DNA damage. TAS-102 also follows an alternative activation pathway via thymidine kinase, and is not a substrate for dihydropyrimidine dehydrogenase. All together this explains the efficacy in 5FU-resistant models. In early clinical studies, the twice-daily schedule (5 days on, 2 days rest) for 2 weeks every 4 weeks, led to a significant disease control rate in various malignancies. This schedule showed consistent activity in two randomized trials on fluoropyrimidine refractory colorectal cancer patients, reflected by an increase of 2–3 months in overall survival in the TAS-102 group compared with placebo. Considering the impressive preclinical potential of various combinations TAS-102 has the promise to become an alternative for 5FU-resistant cancer. PMID:26557901

A study was made of the effects of 5-fluorouracil (FU) and x irradiation, separately and in combination, upon multiple metastatic tumors within individual patients. Fourteen cases satisfied the criteria for a controlled study. In 4, the effects of irradiation alone were greater than the combination, in 4 the effects were equal, and in 6 the effects of irradiation were less than those of combination therapy. This study failed to demonstrate a significant alteration in the tumor response by the addition of FU to x irradiation. Four instances of unusual reactions in previously irradiated skin were noted following FU administration. (auth)

Targeting chemotherapy-resistant leukemia by combining DNT cellular therapy with conventional chemotherapy.

2018-04-24

While conventional chemotherapy is effective at eliminating the bulk of leukemic cells, chemotherapy resistance in acute myeloid leukemia (AML) is a prevalent problem that hinders conventional therapies and contributes to disease relapse, and ultimately patient death. We have recently shown that allogeneic double negative T cells (DNTs) are able to target the majority of primary AML blasts in vitro and in patient-derived xenograft models. However, some primary AML blast samples are resistant to DNT cell therapy. Given the differences in the modes of action of DNTs and chemotherapy, we hypothesize that DNT therapy can be used in combination with conventional chemotherapy to further improve their anti-leukemic effects and to target chemotherapy-resistant disease. Drug titration assays and flow-based cytotoxicity assays using ex vivo expanded allogeneic DNTs were performed on multiple AML cell lines to identify therapy-resistance. Primary AML samples were also tested to validate our in vitro findings. Further, a xenograft model was employed to demonstrate the feasibility of combining conventional chemotherapy and adoptive DNT therapy to target therapy-resistant AML. Lastly, blocking assays with neutralizing antibodies were employed to determine the mechanism by which chemotherapy increases the susceptibility of AML to DNT-mediated cytotoxicity. Here, we demonstrate that KG1a, a stem-like AML cell line that is resistant to DNTs and chemotherapy, and chemotherapy-resistant primary AML samples both became more susceptible to DNT-mediated cytotoxicity in vitro following pre-treatment with daunorubicin. Moreover, chemotherapy treatment followed by adoptive DNT cell therapy significantly decreased bone marrow engraftment of KG1a in a xenograft model. Mechanistically, daunorubicin increased the expression of NKG2D and DNAM-1 ligands on KG1a; blocking of these pathways attenuated DNT-mediated cytotoxicity. Our results demonstrate the feasibility and benefit of using DNTs as an immunotherapy after the administration of conventional chemotherapy.

To evaluate the short and long-term effects of regimens containing INH, RFP with varied chemotherapy courses on culture-positive pneumoconio-tuberculosis. 79 patients with culture-positive pneumoconio-tuberculosis were divided into three groups according to chemotherapy duration: 9-months group (M9: 2SHRZ/7HRE) 28 cases, 12-month group (2SHRZ/10HRE) 25 cases, 18-month group (M18: 2SHRZ/10HRE/6HR) 26 cases. Evaluating the efficacy of regimens depended predominantly on sputum bacteriological conversion, and the patients who completed the regimens were followed up for 5-8 years. Sputum negative conversion rates of three groups at the end of chemotherapy were 83%, 96%, 95%, and their recurrent rates in follow-up period 41%, 4% and 5% respectively. Of all patients who completed the regimens bacteriological relapse rates from the first to fourth year are 6%, 8%, 2%, 2% in the follow-up period. There was no bacteriological relapse from fifth to eighth year. It is effective for SHRZ/HRE combination with 12-months course to retreated tubercle bacillus positive pneumoconio-tuberculosis, and it is appropriate for such patients to be followed up for 4-5 years.

Rolapitant: A Review in Chemotherapy-Induced Nausea and Vomiting.

PubMed

Heo, Young-A; Deeks, Emma D

2017-10-01

Oral rolapitant (Varubi™; Varuby ® ), a long-acting neurokinin-1 (NK 1 ) receptor antagonist (RA), is indicated in the USA and EU as part of an antiemetic regimen to prevent delayed chemotherapy-induced nausea and vomiting (CINV) in adults receiving highly or moderately emetogenic chemotherapy (HEC or MEC). In randomized, phase III trials, a single oral dose of rolapitant 180 mg was effective in preventing delayed CINV compared with placebo, when each was used in combination with a 5-HT 3 RA plus dexamethasone, in adults receiving their first course of HEC or MEC. The benefits of rolapitant were maintained over multiple cycles of chemotherapy. The tolerability profile of rolapitant is similar to that of placebo and consistent with that of other NK 1 RAs. However, rolapitant differs from other existing NK 1 RAs in that it does not interact with CYP3A4, thereby negating the need for dexamethasone dose adjustments and potentially making rolapitant a more suitable option for patients receiving CYP3A4 substrates. Thus, oral rolapitant is an effective and well tolerated NK 1 RA that expands the treatment options for preventing delayed CINV in adults receiving HEC or MEC.

Summary Background In the Medical Research Council (MRC) COIN trial, the epidermal growth factor receptor (EGFR)-targeted antibody cetuximab was added to standard chemotherapy in first-line treatment of advanced colorectal cancer with the aim of assessing effect on overall survival. Methods In this randomised controlled trial, patients who were fit for but had not received previous chemotherapy for advanced colorectal cancer were randomly assigned to oxaliplatin and fluoropyrimidine chemotherapy (arm A), the same combination plus cetuximab (arm B), or intermittent chemotherapy (arm C). The choice of fluoropyrimidine therapy (capecitabine or infused fluouroracil plus leucovorin) was decided before randomisation. Randomisation was done centrally (via telephone) by the MRC Clinical Trials Unit using minimisation. Treatment allocation was not masked. The comparison of arms A and C is described in a companion paper. Here, we present the comparison of arm A and B, for which the primary outcome was overall survival in patients with KRAS wild-type tumours. Analysis was by intention to treat. Further analyses with respect to NRAS, BRAF, and EGFR status were done. The trial is registered, ISRCTN27286448. Findings 1630 patients were randomly assigned to treatment groups (815 to standard therapy and 815 to addition of cetuximab). Tumour samples from 1316 (81%) patients were used for somatic molecular analyses; 565 (43%) had KRAS mutations. In patients with KRAS wild-type tumours (arm A, n=367; arm B, n=362), overall survival did not differ between treatment groups (median survival 17·9 months [IQR 10·3–29·2] in the control group vs 17·0 months [9·4–30·1] in the cetuximab group; HR 1·04, 95% CI 0·87–1·23, p=0·67). Similarly, there was no effect on progression-free survival (8·6 months [IQR 5·0–12·5] in the control group vs 8·6 months [5·1–13·8] in the cetuximab group; HR 0·96, 0·82–1·12, p=0·60). Overall response rate increased from 57% (n=209) with chemotherapy alone to 64% (n=232) with addition of cetuximab (p=0·049). Grade 3 and higher skin and gastrointestinal toxic effects were increased with cetuximab (14 vs 114 and 67 vs 97 patients in the control group vs the cetuximab group with KRAS wild-type tumours, respectively). Overall survival differs by somatic mutation status irrespective of treatment received: BRAF mutant, 8·8 months (IQR 4·5–27·4); KRAS mutant, 14·4 months (8·5–24·0); all wild-type, 20·1 months (11·5–31·7). Interpretation This trial has not confirmed a benefit of addition of cetuximab to oxaliplatin-based chemotherapy in first-line treatment of patients with advanced colorectal cancer. Cetuximab increases response rate, with no evidence of benefit in progression-free or overall survival in KRAS wild-type patients or even in patients selected by additional mutational analysis of their tumours. The use of cetuximab in combination with oxaliplatin and capecitabine in first-line chemotherapy in patients with widespread metastases cannot be recommended.

A paradigm shift seems to emerge, not only in industrial engineering ("Industry 4.0") but also in medicine: we are on the threshold to "Medicine 4.0". For many years, molecular biology had a leading position in life sciences, but today scientists start realizing that microelectronic systems, due to an increasing miniaturization, are reaching the scale of human cells and consequently can be used for therapeutic approaches. This article shows how microelectronics can play a major role in modern medicine, through the example of customized chemotherapy. This consists in determining, before the beginning of the treatment, what kind of chemotherapy or drug combination will be most effective for a given patient, and at which dose. This of course allows the lessening of a patient burden during treatment, but also to be more efficient and, in the long run, to save money. In order to do this, we have developed the Intelligent Microplate Reader (IMR), which allows us to accurately test different drugs on living cells by mimicking part of their usual environment. © 2018 médecine/sciences – Inserm.

Efficacy of triplet regimen antiemetic therapy for chemotherapy-induced nausea and vomiting (CINV) in bone and soft tissue sarcoma patients receiving highly emetogenic chemotherapy, and an efficacy comparison of single-shot palonosetron and consecutive-day granisetron for CINV in a randomized, single-blinded crossover study

The first aim of this study was to evaluate combination antiemetic therapy consisting of 5-HT3 receptor antagonists, neurokinin-1 receptor antagonists (NK-1RAs), and dexamethasone for multiple high emetogenic risk (HER) anticancer agents in bone and soft tissue sarcoma. The second aim was to compare the effectiveness of single-shot palonosetron and consecutive-day granisetron in a randomized, single-blinded crossover study. A single randomization method was used to assign eligible patients to the palonosetron or granisetron arm. Patients in the palonosetron arm received a palonosetron regimen during the first and third chemotherapy courses and a granisetron regimen during the second and fourth courses. All patients received NK-1RA and dexamethasone. Patients receiving the palonosetron regimen were administered 0.75 mg palonosetron on day 1, and patients receiving the granisetron regimen were administered 3 mg granisetron twice daily on days 1 through 5. All 24 patients in this study received at least 4 chemotherapy courses. A total of 96 courses of antiemetic therapy were evaluated. Overall, the complete response CR rate (no emetic episodes and no rescue medication use) was 34%, while the total control rate (a CR plus no nausea) was 7%. No significant differences were observed between single-shot palonosetron and consecutive-day granisetron. Antiemetic therapy with a 3-drug combination was not sufficient to control chemotherapy-induced nausea and vomiting (CINV) during chemotherapy with multiple HER agents for bone and soft tissue sarcoma. This study also demonstrated that consecutive-day granisetron was not inferior to single-shot palonosetron for treating CINV. PMID:25533447

A meeting of regional experts was convened in Manila, Philippines, to develop a resource-stratified chemotherapy-induced nausea and vomiting (CINV) management guideline. In patients treated with highly emetogenic chemotherapy in general clinical settings, triple therapy with a serotonin (5-hydroxytryptamine-3 [5-HT 3 ]) antagonist (preferably palonosetron), dexamethasone, and aprepitant is recommended for acute CINV prevention. In resource-restricted settings, triple therapy is still recommended, although a 5-HT 3 antagonist other than palonosetron may be used. In both general and resource-restricted settings, dual therapy with dexamethasone (days 2 to 4) and aprepitant (days 2 to 3) is recommended to prevent delayed CINV. In patients treated with moderately emetogenic chemotherapy, dual therapy with a 5-HT 3 antagonist, preferably palonosetron, and dexamethasone is recommended for acute CINV prevention in general settings; any 5-HT 3 antagonist can be combined with dexamethasone in resource-restricted environments. In general settings, for the prevention of delayed CINV associated with moderately emetogenic chemotherapy, corticosteroid monotherapy on days 2 and 3 is recommended. If aprepitant is used on day 1, it should be continued on days 2 and 3. Prevention of delayed CINV with corticosteroids is preferred in resource-restricted settings. The expert panel also developed CINV management guidelines for anthracycline plus cyclophosphamide combination schedules, multiday cisplatin, and chemotherapy with low or minimal emetogenic potential, and its recommendations are detailed in this review. Overall, these regional guidelines provide definitive guidance for CINV management in general and resource-restricted settings. These consensus recommendations are anticipated to contribute to collaborative efforts to improve CINV management in Southeast Asia.

Rolapitant, a novel neurokinin-1 receptor antagonist (RA), was shown to protect against delayed chemotherapy-induced nausea and vomiting (CINV) during the first cycle of moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC) in randomized, double-blind trials. This analysis explored the efficacy and safety of rolapitant in preventing CINV over multiple cycles of MEC or HEC. Patients in one phase III MEC, one phase II HEC, and two phase III HEC clinical trials were randomized to receive oral rolapitant (180 mg) or placebo in combination with a 5-hydroxytryptamine type 3 RA and dexamethasone. Regardless of response in cycle 1, patients could continue the same antiemetic treatment for up to six cycles. On days 6-8 of each subsequent chemotherapy cycle, patients reported the incidence of emesis and/or nausea interfering with normal daily life. Post hoc analyses of pooled safety and efficacy data from the four trials were performed for cycles 2-6. Significantly more patients receiving rolapitant than control reported no emesis or interfering nausea (combined measure) in cycles 2 (p = 0.006), 3 (p < 0.001), 4 (p = 0.001), and 5 (p = 0.021). Over cycles 1-6, time-to-first emesis was significantly longer with rolapitant than with control (p < 0.001). The incidence of treatment-related adverse events during cycles 2-6 was similar in rolapitant (5.5%) and control (6.8%) arms. No cumulative toxicity was observed. Over multiple cycles of MEC or HEC, rolapitant provided superior CINV protection and reduced emesis and nausea interfering with daily life compared with control and remained well tolerated.

To evaluate long-term results of a phase II study of induction and adjuvant gemcitabine and cisplatin (GP) chemotherapy with intensity-modulated radiotherapy (IMRT) in locoregionally advanced nasopharyngeal carcinoma (NPC). One hundred and twelve patients (Stage III: 65, IVA-B: 47) with locoregionally advanced NPC were enrolled in this study. All patients received induction chemotherapy consisting of 1000 mg/m 2 gemcitabine on day 1 and 8, and cisplatin 25 mg/m 2 on day 1-3, every 3 weeks for 2 cycles. Adjuvant chemotherapy for 2 cycles of the same regime was given 28 days after the end of IMRT. The IMRT technique was utilized for all patients. In total, 97.3% patients completed 2 cycles of induction chemotherapy. The overall response rate (RR) of cervical lymph nodes was 89.0%. Acute toxicities were mainly grade 1-2 myleosuppression and vomiting. And 83.9% patients completed 2 cycles of adjuvant chemotherapy. All patients finished IMRT with RR at the end of IMRT for nasopharynx, lymph nodes of neck and retropharyngeal area being 99.1%, 97.9% and 97.7%, respectively. The 5-year local control, regional control, distant metastasis-free and overall survival rates were 93.2%, 92.3%, 89.0% and 82.1%, respectively. The 5-year overall survival of stage III and IVA-B were 87.0%, and 75.5%, respectively. The incidence of grade 3-4 acute radiotherapy-related mucositis was 28.6%. Severe late toxicities were uncommon. IMRT combined with GP for locoregionally advanced NPC is well tolerated, effective, and convenient, and warrants further studies. Copyright © 2017 Elsevier Ltd.

Peritoneal surface malignancy (PSM) is a common manifestation of digestive and gynaecologic malignancies alike. At present, patients with isolated PSM are treated with a combination therapy of cytoreductive surgery (CRS) and hyperthermic peroperative intraperitoneal chemotherapy (HIPEC). The combination of CRS and intraperitoneal (IP) chemotherapy should now be considered standard of care for PSM from appendiceal epithelial cancers, colorectal cancer and peritoneal mesothelioma. Although there is a near universal standardisation regarding the CRS, we are still lacking a much-needed standardisation amongst the various IP chemotherapy treatment modalities used today in clinical practice. Pharmacologic evidence should be generated to answer important questions raised by the myriad of variables associated with IP chemotherapy.

Magnetic iron oxide nanoparticles (MNPs) have been extensively utilized in a wide range of biomedical applications including magnetic hyperthermia agent. To improve the efficiency of the MNPs in therapeutic applications, in this study, we have synthesized CoFe 2 O 4 nanoparticles and its surface was further functionalized with meso-2,3-dimercaptosuccinic acid (DMSA). The anticancer agent, Doxorubucin (DOX) was conjugated with CoFe 2 O 4 @DMSA nanoparticle to evaluate the combined effects of thermotherapy and chemotherapy. The drug delivery efficiency of the DOX loaded CoFe 2 O 4 @DMSA nanoparticles were examined based on magnetically triggered delivery of DOX into the subcellular level of cancer cells by using MDA-MB-231 cell line. The amine part of the DOX molecules were effectively attached through an electrostatic interactions and/or hydrogen bonding interactions with the carboxylic acid groups of the DMSA functionalities present onto the surface of the CoFe 2 O 4 nanoparticles. The DOX loaded CoFe 2 O 4 @DMSA nanoparticles can effectively uptake with cancer cells via typical endocytosis process. After endocytosis, DOX release from CoFe 2 O 4 nanoparticles was triggered by intracellular endosomal/lysosomal acidic environments and the localized heat can be generated under an alternating magnetic field (AMF). In the presence of AMF, the released DOX molecules were accumulated with high concentrations into the subcellular level at a desired sites and exhibited a synergistic effect of an enhanced cell cytotoxicity by the combined effects of thermal-chemotherapy. Importantly, pH- and thermal-responsive Dox-loaded CoFe 2 O 4 nanoparticles induced significant cellular apoptosis more efficiently mediated by active mitochondrial membrane and ROS generation than the free Dox. Thus, the Dox-loaded CoFe 2 O 4 @DMSA nanoparticles can be used as a potential therapeutic agent in cancer therapy by combining the thermo-chemotherapy techniques. Copyright © 2016.

Paracoccidioidomycosis is a granulomatous pulmonary infection that is generally controlled by chemotherapy. The efficacy of treatment, however, is limited by the status of the host immune response. The inhibition of a Th-2 immunity or the stimulation of Th-1 cytokines generally increases the efficacy of antifungal drugs.1 This has been achieved by immunization with an internal peptide of the major diagnostic antigen gp43 of Paracoccidioides brasiliensis. Peptide 10 (QTLIAIHTLAIRYAN) elicits an IFN-γ rich Th-1 immune response that protects against experimental intratracheal infection by this fungus. The combination of chemotherapy with P10 immunization showed additive protective effect even after 30 d of infection or in anergic mice, rendering in general, increased production of IL-12 and IFN-γ and reduction of IL-4 and IL-10. Immunotherapy with P10 even in the absence of simultaneous chemotherapy has been effective using various protocols, adjuvants, nanoparticles, P10-primed dendritic cells, and especially a combination of plasmids encoding the P10 minigene and IL-12. Gene therapy, in a long-term infection protocol succeeded in the virtual elimination of the fungus, preserving the lung structure, free from immunopathological side effects. PMID:22894948

Malignant gliomas remain refractory to several therapeutic approaches and the requirement for novel treatment modalities is critical to combat this disease. Etoposide is a topoisomerase-II inhibitor, which promotes DNA damage and apoptosis of cancer cells. In this study, we prepared albumin with embedded magnetic nanoparticles and etoposide for in vitro evaluation of combined hyperthermia and chemotherapy. Magnetic nanoparticles were prepared by a modified co-precipitation method in the presence of human serum albumin and etoposide. A cellular proliferation assay was used to determine the effects of these nanostructures on the viability of U87 glioma cells in an alternating magnetic field. The in vitro experiments showed that cell viability decreased to 59.4% after heat treatment alone and to 53.8% on that with free etoposide, while combined treatment resulted in 7.8% cell viability. Integrating hyperthermia and chemotherapy using albumin co-embedded magnetic nanoheaters and etoposide may represent a promising therapeutic option for glioblastoma.

Vascular disrupting agents preferentially target the established but abnormal tumor vasculature, resulting in extensive intratumoral hypoxia and cell death. However, a rim of viable tumor tissue remains from which angiogenesis-dependent regrowth can occur, in part through the mobilization and tumor colonization of circulating endothelial progenitor cells (CEP). Cotreatment with an agent that blocks CEPs, such as a vascular endothelial growth factor pathway-targeting biological antiangiogenic drug, results in enhanced antitumor efficacy. We asked whether an alternative therapeutic modality, low-dose metronomic chemotherapy, could achieve the same result given its CEP-targeting effects. We studied the combination of the vascular disrupting agent OXi4503 with daily administration of CEP-inhibiting, low-dose metronomic cyclophosphamide to treat primary orthotopic tumors with the use of the 231/LM2-4 breast cancer cell line and MeWo melanoma cell line. In addition, CEP mobilization and various tumor characteristics were assessed. We found that daily p.o. low-dose metronomic cyclophosphamide was capable of preventing the CEP spike and tumor colonization induced by OXi4503. This was associated with a decrease in the tumor rim and marked suppression of primary 231/LM2-4 growth in nude as well as severe combined immunodeficient mice. Similar results were found in MeWo-bearing nude mice. The delay in tumor growth was accompanied by significant decreases in microvessel density, perfusion, and proliferation, and a significant increase in tumor cell apoptosis. No overt toxicity was observed. The combination of OXi4503 and metronomic chemotherapy results in prolonged tumor control, thereby expanding the list of therapeutic agents that can be successfully integrated with metronomic low-dose chemotherapy.

Nimotuzumab is a humanized anti-epidermal growth factor receptor IgG1 monoclonal antibody. This phase I study assessed the tolerability, safety, efficacy, and pharmacokinetics of nimotuzumab in combination with chemoradiotherapy in Japanese patients with esophageal cancer. Patients with stage II, III, and IV esophageal cancer were enrolled. Patients were planned to receive nimotuzumab (level 1: 200 mg/wk for 25 weeks; or level 2: 400 mg/wk in the chemoradiation period, 400 mg biweekly in an additional chemotherapy period [8 weeks after the chemoradiation period] and a maintenance therapy period [after chemotherapy to 25 weeks]) combined with cisplatin (75 mg/m 2 on day 1) and fluorouracil (1000 mg/m 2 on days 1-4) in the chemoradiation and additional chemotherapy periods. Radiotherapy was given concurrently at 50.4 Gy. A total of 10 patients were enrolled in level 1. Dose-limiting toxicities were observed in 2 patients (grade 3 infection and renal disorder). Maximum-tolerated dose was estimated to be at least 200 mg/wk and the dose was not escalated to level 2. The most common grade ≥3 toxicities were lymphopenia (90%), leukopenia (60%), neutropenia (50%), and febrile neutropenia, decreased appetite, hyponatremia, and radiation esophagitis (30% each). Neither treatment-related death nor grade ≥3 skin toxicity was observed in any patient. Complete response rate was 50%. Progression-free survival was 13.9 months. One- and 3-year survival rates were 75% and 37.5%, respectively. Immunogenicity was not reported in any patient. Nimotuzumab in combination with concurrent chemoradiotherapy was tolerable and effective for Japanese patients with esophageal cancer. © 2018 The Authors.

The aim was to develop magnetic nanovesicles for chemotherapy and self-controlled hyperthermia that prevent overheating of tissues. Magnetic nanovesicles containing paclitaxel and a dextran-coated biphasic suspension of La0.75Sr0.25MnO3 and Fe3O4 nanoparticles (magnetic nanoparticles) were developed. Encapsulation efficiencies of magnetic nanoparticles and paclitaxel were 67 ± 5 and 83 ± 3%, respectively. Sequential release performed at 37°C for 1 h followed by 44°C for another 1 h (as expected for intratumoral injection), showed a cumulative release of 6.6% (109.6 µg), which was above the IC50 of the drug. In an alternating current magnetic field, the temperature remained controlled at 44°C and a synergistic cytotoxicity of paclitaxel and hyperthermia was observed in MCF-7 cells. Magnetic nanovesicles containing biphasic suspensions La0.75Sr0.25MnO3 and Fe3O4 nanoparticles encapsulating paclitaxel have potential for combined self-controlled hyperthermia and chemotherapy.

POEMS syndrome is a paraneoplastic syndrome caused by an underlying plasma cell proliferative disease. In this study, we examined the treatment outcomes and role of radiotherapy in the management of POEMS syndrome. In total, 33 patients diagnosed with POEMS syndrome were analyzed. These patients presented with osteosclerotic myeloma (OSM, n = 13), Castleman's disease (CD, n = 4), OSM with CD (n = 10), and vascular endothelial growth factor elevation without gross lesions (VEGFe, n = 6), respectively. The patients were treated by radiotherapy alone (n = 4), chemotherapy alone (n = 16), or a combination thereof (n = 9). The clinical response rates of radiotherapy, chemotherapy, and radiotherapy plus chemotherapy were 75%, 69%, and 89%, respectively. In addition, the hematologic response rates were 50%, 69%, and 71%, respectively. Among the six patients with limited multiple lesions who underwent radiotherapy, the clinical symptoms were improved in five patients after radiotherapy. The median progression-free survival (PFS) was 51 months, and the median overall survival (OS) was 65 months. In univariate analysis, the administration of chemotherapy was significantly associated with better PFS (p = 0.007) and OS (p = 0.020). In contrast, underlying VEGFe was a significant factor worsening PFS (p = 0.035) and OS (p = 0.008). Radiotherapy produces a reliable clinical response and is effective in improving POEMS-associated symptoms that are refractory to chemotherapy in selected patients with clustered or limited multiple lesions that can be covered by single radiation field.

We aimed to investigate the patterns of failure (locoregional and distant metastasis), associated factors, and treatment outcomes in nasopharyngeal carcinoma patients treated with intensity-modulated radiation therapy (IMRT) combined with chemotherapy. From April 2006 to December 2011, 68 nasopharyngeal carcinoma patients were treated with IMRT and chemotherapy at our hospital. Median radiation doses delivered to gross tumor volume and positive neck nodes were 66-70 Gy, 63 Gy to clinical target volume, and 50.4-56 Gy to clinically negative neck. The clinical toxicities, patterns of failures, locoregional control, distant metastasis control, disease-free survival, and overall survival were observed. The median follow-up time was 52.2 months (range: 11-87 months). Epstein-Barr virus infection was positive in 63.2% of patients. Overall disease failure developed in 21 patients, of whom 85.8% belonged to stage III/IV disease. Among these, there were seven locoregional recurrences, three regional recurrences with distant metastases, and eleven distant metastases. The median interval from the date of diagnosis to failure was 26.5 months (range: 16-50 months). Six of ten (60%) locoregional recurrences were treated with reirradiation ± concurrent chemotherapy. The 5-year locoregional control, distant metastasis control, disease-free survival, and overall survival rates of whole cohort were 81.1%, 74.3%, 60.1%, and 73.4%, respectively. Cox regression analyses revealed that neoadjuvant chemotherapy, age, and Epstein-Barr virus were independent predictors for disease-free survival. Neoadjuvant chemotherapy followed by IMRT with or without chemotherapy improves the long-term survival of Saudi patients with nasopharyngeal carcinoma. Distant metastasis was the main pattern of treatment failure. Neoadjuvant chemotherapy, age, and Epstein-Barr virus status before IMRT were important independent prognostic factors.

Accumulating preclinical evidence suggests that anticancer immune responses contribute to the success of chemotherapy. The predictive significance of tumor-infiltrating lymphocytes (TILs) for response to neoadjuvant chemotherapy in non-small cell lung cancer (NSCLC) remains unknown. The aim of this study was to investigate the prognostic and predictive value of TIL subtypes in patients with advanced NSCLC treated with platinum-based chemotherapy. In total, 159 patients with stage III and IV NSCLC were retrospectively enrolled. The prevalence of CD3(+), CD4(+), CD8(+) and Foxp3(+) TILs was assessed by immunohistochemistry in tumor tissue obtained before chemotherapy. The density of TILs subgroups was treated as dichotomous variables using the median values as cutoff. Survival curves were estimated by the Kaplan-Meier method, and differences in overall survival between groups were determined using the Log-rank test. Prognostic effects of TIL subsets density were evaluated by Cox regression analysis. The presence of CD3(+), CD4(+), CD8(+), and FOXP3(+) TILs was not correlated with any clinicopathological features. Neither the prevalence of TILs nor combined analysis displayed obvious prognostic performances for overall survival in Cox regression model. Instead, higher FOXP3(+)/CD8(+) ratio in tumor sites was an independent factor for poor response to platinum-based chemotherapy in overall cohort. These findings suggest that immunological CD8(+) and FOXP3(+)Tregs cell infiltrate within tumor environment is predictive of response to platinum-based neoadjuvant chemotherapy in advanced NSCLC patients. The understanding of the clinical relevance of the microenvironmental immunological milieu might provide an important clue for the design of novel strategies in cancer immunotherapy.

[Efficacy of granisetron for preventing chemotherapy-induced nausea and vomiting in patients with acute myelogenous leukemia treated with a combination of anthracycline and cytarabine].

In Japan, the combination of anthracycline and cytarabine(Ara-C)is a standard therapy for acute myelogenous leukemia(AML). Chemotherapy-induced nausea and vomiting(CINV)are frequently reported as side effects related to the administration of these regimens. In our hospital, patients received prophylactic granisetron at a dose of 3 mg daily during chemotherapy. However, granisetron is known to induce constipation as a side effect. The present study evaluated the efficacy of a single dose of granisetron administered throughout the entire period of chemotherapy in AML patients receiving anthracycline and Ara-C combination therapy, and also examined the incidence of constipation during chemotherapy. From July 2008 to December 2010, all patients with AML treated using anthracycline and Ara-C combination therapy were registered in the study. This retrospective study investigated the patients' background and the incidence of CINV and constipation from the patients' records. The efficacy of granisetron was measured on each day using the complete regression(no vomiting and no rescue medication; CR)rate. A total of 45 patients were included in the study(27 male; 18 female), and received a total 68 courses(56 of induction therapy; 12 of consolidation therapy)of the regimens. The CR rate and the incidence of constipation on the final day of chemotherapy were 61. 8% and 63. 2%, respectively. As the duration of chemotherapy increased, the CR rate tended to decrease, whereas the incidence of constipation tended to increase. The CR rate in this study was 61. 8%, thus indicating that there is still room for improvement. The combination of dexamethasone and a neurokinin-1 receptor antagonist, or the changeover from granisetron to palonosetron could therefore increase the CR rate.

Combined chemotherapy and radiotherapy (without surgery) compared with radiotherapy alone in localized carcinoma of the esophagus.

Esophageal carcinoma can be managed primarily with either a surgical or radiotherapeutic (non surgical) approach. Strategies to improve the outcome of either modality alone include the use of combined modalities. Combination chemotherapy radiotherapy is one approach that has been explored over the years with increasing application in clinical practice especially in North America. To evaluate the effectiveness of combined chemotherapy and radiotherapy versus radiotherapy alone in the outcome of patients with localized esophageal carcinoma. Outcomes of interest include overall survival, cause specific survival, local recurrence, dysphagia relief, quality of life, acute and chronic toxicities. The Cochrane strategy for identifying randomized trials was combined with MeSH headings including esophageal neoplasms, radiotherapy, chemotherapy combined modality, drug therapy combination. Medline, Cancerlit and Embase were searched using this strategy. In addition, the Cochrane library was also searched. References from relevant articles and personal files were included. Randomized controlled trials in patients with localized esophageal cancer, with one arm employing radiotherapy alone, and one arm employing combination radiotherapy chemotherapy were included. Studies comparing non chemotherapy agents such as pure radiotherapy sensitisers, immunostimulants, planned esophagectomy, were excluded. Data were extracted by two independent reviewers, and the trial quality was assessed using both the Jadad scoring and Detsky checklist. Sensitivity analysis was planned to explore sources of heterogeneity where heterogeneity existed. The factors hypothesized a priori included combination versus sequential treatment, quality of study, biological effective radiotherapy dose (i.e. Radiotherapy dose) cisplatin versus non cisplatin containing trials, and 5FU versus non 5FU containing trials. Odds Ratio (OR) and 95% confidence limits were used to assess the significance of the difference between the treatment arms. Absolute risk difference and number needed to treat (NNT) were used to express the magnitude of difference where appropriate. Thirteen randomized trials were included in the analysis. There were eight concomitant and five sequential radiotherapy and chemotherapy (RTCT) studies. The studies were analyzed separately due to observed heterogeneity across all the studies and biological considerations. Concomitant RTCT provided significant overall reduction in mortality at 1 and 2 years. The mortality in the control arms was 67% and 86% respectively. Combined RTCT provided an absolute reduction of mortality by 9% (95% CI 2-17%) and 8% (95% CI 1-17%) respectively. Expressed as NNT, this is 11 and 10 respectively. At longer follow up, the results were heterogeneous, cautioning against pooling of the data. There was a reduction in the overall local recurrence rate. The local recurrence rate for the control arms was in the order of 69%. Combined RTCT provided an absolute reduction of local recurrence rate of 5% (95% CI 4-26%) with a NNT of 7. There was significant increase of severe and life threatening toxicities with a NNH of 6, with this approach. With the sensitivity analysis, there was a suggestion that cisplatin based and 5FU based chemotherapy studies were reasonable regimens to employ when using this strategy. The results from the sequential RTCT studies were heterogeneous and could not be pooled. Factors hypothesized a priori did not identify any single source that could account for a significant component of the heterogeneity. Examining the results individually, there was no data to support clinical benefit. This approach was also accompanied by significant toxicities. When a non-operative approach is selected, then concomitant RTCT is superior to the RT alone. This approach is accompanied by significant toxicities. In patients who are in good general condition, and the risk benefit has been thoroughly discussed with the patient, concomitant RTCT should be considered for the management of esophageal cancer compared with radiotherapy alone.

We prepared pH-sensitive drug-dendrimer conjugate-hybridized gold nanorod as a promising platform for combined cancer photothermal-chemotherapy under in vitro and in vivo conditions. Poly(ethylene glycol)-attached PAMAM G4 dendrimers (PEG-PAMAM) were first covalently linked on the surface of mercaptohexadecanoic acid-functionalized gold nanorod (MHA-AuNR), with subsequent conjugation of anti-cancer drug doxorubicin (DOX) to dendrimer layer using an acid-labile-hydrazone linkage to afford PEG-DOX-PAMAM-AuNR particles. The particles with a high PEG-PAMAM dendrimer coverage density (0.28 per nm(2) AuNR) showed uniform sizes and excellent colloidal stability. In vitro drug release studies demonstrated that DOX released from PEG-DOX-PAMAM-AuNR was negligible under normal physiological pH, but it was enhanced significantly at a weak acidic pH value. The efficient intracellular acid-triggered DOX release inside of lysosomes was confirmed using confocal laser scanning microscopy analysis. Furthermore, the combined photothermal-chemo treatment of cancer cells using PEG-DOX-PAMAM-AuNR for synergistic hyperthermia ablation and chemotherapy was demonstrated both in vitro and in vivo to exhibit higher therapeutic efficacy than either single treatment alone, underscoring the great potential of PEG-DOX-PAMAM-AuNR particles for cancer therapy.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lacher, M.J.; Toner, K.

The menstrual cycle, pregnancies, and offspring were evaluated before and after initial combined radiation (RT) and chemotherapy with thiotepa, vinblastine, vincristine, procarbazine, and prednisone (TVPP), in 34 women between the ages of 18 and 44 (median 26.5 years) treated for Stage II and Stage III Hodgkin's disease. The median range of follow-up is 83.1 months (range 40.5-140). After therapy 94.1% (32/34) continued to menstruate. Two of the four patients over the age of 35 ceased to menstruate. All patients under the age of 35 continued to menstruate (30/30). Age at the time of diagnosis was the only factor affecting changemore » in menses with a significant probability (p = .001) that women greater than 30 years of age will experience some change in menstrual pattern. Seventeen pregnancies occurred in 12 women after therapy; 2 had 4 elective abortions; 10 delivered 12 children with normal physical development; 1 will deliver six months from now. Twelve of thirteen patients who wanted to become pregnant have conceived. The ability to become pregnant and deliver normal children after intensive treatment with combined radiation and chemotherapy (RT/TVPP) was comparable to the patients' pretreatment record.« less

To evaluate the efficacy and safety of pelvic irradiation combined systematic chemotherapy in patients with locally advanced (cT3-T4 and/or cN+) rectal cancer and synchronous unresectable distant metastases. A total of 76 eligible patients who received pelvic radiotherapy and concurrent capecitabine-based chemotherapy were retrospectively reviewed. Patients survival curves were constructed using the Kaplan-Meier method, and a multivariate analysis was performed to identify independent prognostic factors. Most of the adverse events were mild during the period of combined chemoradiotherapy. Twenty-two patients experienced resection of primary tumour and 16 patients underwent radical surgery of all lesions. Only five patients had pelvic progression during the follow-up period. The median progression-free survival and median overall survival were 13 and 30 months, respectively. Radical surgery of all lesions following chemoradiotherapy was found to be an independent prognostic factor according to multivariate analysis. Pelvic irradiation combined with systematic chemotherapy in patients with locally advanced rectal cancer and synchronous unresectable distant metastases is effective and tolerable, both for pelvic and distant control. A curative resection following chemoradiotherapy was associated with prolonged survival. Copyright © 2016 Société française de radiothérapie oncologique (SFRO). Published by Elsevier SAS.

Concomitant chemo-radiotherapy is the standard treatment for advanced nasopharyngeal carcinoma (NPC). Induction chemotherapy may improve the results further by enhancing both loco-regional and distant control. Fifty patients with untreated, stage IV (UICC 1992) undifferentiated NPC were initially treated with three courses of epidoxorubicin, 90 mg/m(2), day 1 and cisplatin, 40 mg/m(2), days 1 and 2, every three weeks and then underwent three courses of cisplatin, 20 mg/m(2)/day, days 1-4 and fluorouracil, 200mg/m(2)/day, days 1-4 (weeks 1, 4, 7), alternated to three splits of radiation (week 2-3, 5-6, 8-9-10) up to 70 Gy. All patients but one received 3 cycles of induction chemotherapy. Toxicities from induction chemotherapy were grade III or IV mucositis (2%), grade III or IV nausea/vomiting (22%), grade III or IV hematological toxicity (6%). At the end of induction phase 12% of CRs, 84% of PRs were recorded. Toxicities from alternating chemo-radiotherapy were grade III or IV mucositis (30%), grade III or IV nausea/vomiting (8%), grade III or IV hematological toxicity (24%). Overall, 86% of CRs and 14% of PRs were observed. Four-year progression free survival and overall survival rates are 71% and 81%, respectively. In a small number of patients studied, no correlation between the level of EGFR overexpression and outcomes was detected. In locally advanced UNPC our combined program including induction chemotherapy followed by alternating chemo-radiotherapy is active and gives promising long-term outcomes with acceptable toxicity and optimal patients' compliance. This program merits to be tested in a phase III trial.

Oral mucositis is one of the common side effects of chemotherapy treatment with potentially severe implications. Despite several treatment approaches by conventional and complementary western medicine, the therapeutic outcome is often not satisfactory. Traditional Chinese Medicine (TCM) offers empirical herbal formulas for the treatment of oral ulceration which are used in adaptation to chemotherapy-induced mucositis. While standard concepts for TCM treatment do not exist and acceptance by conventional oncologists is still low, we conducted a review to examine the evidence of Chinese herbal treatment in oral mucositis. Eighteen relevant studies on 4 single herbs, 2 combinations of 2 herbs, and 11 multiherbal prescriptions involving 3 or more compounds were included. Corresponding molecular mechanisms were investigated. The knowledge about detailed herbal mechanisms, especially in multi-herbal prescriptions is still limited. The quality of clinical trials needs further improvement. Meta-analysis on the existent database is not possible but molecular findings on Chinese medicinal herbs indicate that further research is still promising for the treatment of chemotherapy-induced oral mucositis.

Although the outcome of patients with acute lymphoblastic leukemia (ALL) has been improved continuously by chemotherapy and tyrosine kinase inhibitors, prognosis of patients with Philadelphia chromosome positive (Ph(+)) ALL still remains poor. Since further intensification of chemotherapy is limited by toxic side effects and patients with high risk of transplant-related mortality are not eligible for allogeneic stem cell transplantation new treatment strategies are urgently needed for the prevention of Ph(+) ALL relapse. There is increasing evidence that the immune system plays an essential role for the eradication or immunologic control of remaining leukemia cells. We developed several DNA-based vaccines encoding a BCR-ABL(p185) specific peptide and GM-CSF, and CD40-L, IL-27 or IL-12 and evaluated the preventive and therapeutic efficacy against a lethal challenge of syngeneic Ph(+) ALL in Balb/c mice. In vivo cell depletion assays and cytokine expression studies were performed and the efficacy of the DNA vaccine was compared with 6-mercaptopurine (6-MP) alone and the combination of the DNA vaccine and 6-MP. Preventive immunization with the vaccine BCR-ABL/GM-CSF/IL-12 and the TLR-9 agonist dSLIM induced an innate and adaptive immune response mediated by NK-cells, CD4(+) T-cells and CD8(+) T-cells leading to a survival rate of 80%. Therapeutic vaccination resulted in a significantly longer leukemia-free survival (40.7 days vs. 20.4 days) and a higher survival rate (56% vs. 10%) compared to chemotherapy with 6-MP. Remarkably, in combination with the vaccine 6-MP acted synergistically and led to 100% survival. These results demonstrate that minimal residual disease of Ph(+) ALL can be significantly better controlled by a combined treatment approach of immunotherapy and chemotherapy. This provides a rationale for improving maintenance therapy in order to reduce the relapse rate in patients with Ph(+) ALL. Copyright © 2012 Elsevier Ltd. All rights reserved.

Pineoblastoma is a rare pineal region brain tumor. Treatment strategies have reflected those for other malignant embryonal brain tumors. Original prospective treatment and outcome data from international trial groups were pooled. Cox regression models were developed considering treatment elements as time-dependent covariates. Data on 135 patients with pineoblastoma aged 0.01-20.7 (median 4.9) years were analyzed. Median observation time was 7.3 years. Favorable prognostic factors were age ≥4 years (hazard ratio [HR] for progression-free survival [PFS] 0.270, P < .001) and administration of radiotherapy (HR for PFS 0.282, P < .001). Metastatic disease (HR for PFS 2.015, P = .006), but not postoperative residual tumor, was associated with unfavorable prognosis. In 57 patients <4 years old, 5-year PFS/overall survival (OS) were 11 ± 4%/12 ± 4%. Two patients survived after chemotherapy only, while 3 of 16 treated with craniospinal irradiation (CSI) with boost, and 3 of 5 treated with high-dose chemotherapy (HDCT) and local radiotherapy survived. In 78 patients aged ≥4 years, PFS/OS were 72 ± 7%/73 ± 7% for patients without metastases, and 50 ± 10%/55 ± 10% with metastases. Seventy-three patients received radiotherapy (48 conventionally fractionated CSI, median dose 35.0 [18.0-45.0] Gy, 19 hyperfractionated CSI, 6 local radiotherapy), with (n = 68) or without (n = 6) chemotherapy. The treatment sequence had no impact; application of HDCT had weak impact on survival in older patients. Survival is poor in young children treated without radiotherapy. In these patients, combination of HDCT and local radiotherapy may warrant further evaluation in the absence of more specific or targeted treatments. CSI combined with chemotherapy is effective for older non-metastatic patients. © The Author(s) 2016. Published by Oxford University Press on behalf of the Society for Neuro-Oncology.

Medical treatment of advanced non-small cell lung cancer in elderly patients: a review of the role of chemotherapy and targeted agents.

2013-07-01

Lung cancer is the leading cause of cancer related mortality worldwide. Non-small cell lung cancer (NSCLC) accounts for 85% of all cases. Half of the patients at diagnosis of NSCLC are over seventy years old; therefore, the elderly represent a large subgroup of patients affected by advanced NSCLC in our clinical practice. Nevertheless, the elderly are under-represented in clinical trials. Given the fact that old age is frequently associated with several comorbidities, poor general conditions and physiologic reduction in organ function, clinicians must carefully choose the best treatment option for elderly patients with advanced NSCLC, always taking into account the expected risks and benefits. In this paper we perform a review of literature evidence regarding the medical treatment of elderly patients affected by advanced NSCLC, encompassing single-agent chemotherapy, doublet chemotherapy and targeted agents. We conclude that single-agent chemotherapy with a third generation agent (vinorelbine, taxanes, gemcitabine) represents a valid treatment option for elderly patients who are not eligible for a combination chemotherapy due to clinical features such as comorbidities, poor performance status and inadequate organ function. Platinum-based doublet chemotherapy shows similar efficacy in elderly patients as compared to their younger counterpart, despite greater treatment related toxicity and it is indicated in elderly patients with ECOG PS: 0-2, adequate organ function and no major comorbidities. Elderly patients affected by epidermal growth factor receptor (EGFR) mutated NSCLC benefit mostly from a tyrosine kinase inhibitor of EGFR (erlotinib, gefitinib) which is associated with a good toxicity profile. Currently there are no available data to strongly support the use of bevacizumab in combination with first line chemotherapy in the treatment of older adults. Elderly patients affected by NSCLC harboring the EML4-ALK translocation could benefit mostly from a treatment with an oral inhibitor of such a rearrangement (crizotinib).

Purpose To determine the feasibility of using intraesophageal radiofrequency (RF) hyperthermia to enhance local chemotherapy in a rat model with orthotopic esophageal squamous cancers. Materials and Methods The animal protocol was approved by the institutional animal care and use committee and the institutional review board. Human esophageal squamous cancer cells were transduced with luciferase lentiviral particles. Cancer cells, mice with subcutaneous cancer esophageal xenografts, and nude rats with orthotopic esophageal cancers in four study groups of six animals per group were treated with (a) combination therapy of magnetic resonance imaging heating guidewire–mediated RF hyperthermia (42°C) plus local chemotherapy (cisplatin and 5-fluorouracil), (b) chemotherapy alone, (c) RF hyperthermia alone, and (d) phosphate-buffered saline. Bioluminescent optical imaging and transcutaneous ultrasonographic imaging were used to observe bioluminescence signal and changes in tumor size among the groups over 2 weeks, which were correlated with subsequent histologic results. The nonparametric Mann-Whitney U test was used for comparisons of variables. Results Compared with chemotherapy alone, RF hyperthermia alone, and phosphate-buffered saline, combination therapy with RF hyperthermia and chemotherapy induced the lowest cell proliferation (relative absorbance of formazan: 23.4% ± 7, 44.6% ± 7.5, 95.8% ± 2, 100%, respectively; P < .0001), rendered the smallest relative tumor volume (0.65 mm3 ± 0.15, P < .0001) and relative bioluminescence optical imaging photon signal (0.57 × 107 photons per second per square millimeter ± 0.15, P < .001) of mice with esophageal cancer xenografts, as well as the smallest relative tumor volume (0.68 mm3 ± 0.13, P < .05) and relative photon signal (0.56 × 107 photons per second per square millimeter ± 0.11. P < .001) of rat orthotopic esophageal cancers. Conclusion Intraesophageal RF hyperthermia can enhance the effect of chemotherapy on esophageal squamous cell cancers. © RSNA, 2016 PMID:27404050

Surgery combined with chemotherapy is the standard treatment for gastric cancer (GC); however, chemotherapy-relative adverse effects are common and result in malnutrition and a poor prognosis. In addition, compliance to postoperative chemotherapy remains a problem. This study aimed to prospectively investigate the effect of educational and nutritional interventions on the nutritional status and compliance of GC patients undergoing postoperative chemotherapy. A total of 144 GC patients were randomized into an intervention group that received intensive individualized nutritional and educational interventions during the entire course of chemotherapy and control group that received basic nutrition care and health education during hospitalization. The nutritional status and compliance between the two groups were compared. The interventions significantly improved calorie and iron intake within 24 h after the first chemotherapy session, and improved patients' weight, hemoglobin, total serum protein, and albumin levels during the entire course of chemotherapy. The compliance rate with chemotherapy was significantly higher in the intervention group than in the control group (73.61% vs. 55.56%, P = 0.024). A combination of nutritional and educational interventions provided beneficial effect on the nutrition status and compliance of gastric patients undergoing postoperative chemotherapy, which is worthy of clinical application.

This review will discuss the evolution of the role of chemotherapy in the treatment of locally advanced head and neck cancer (HNC), over the last few decades. Studies were identified by searching PubMed electronic databases. Surgery followed by radiotherapy (RT) or definitive RT are potentially curative approaches for locally advanced HNC. While chemotherapy itself is not curative, it can improve cure rates when given as an adjunct to RT. The benefit of combining chemotherapy with RT is related to the timing of the chemotherapy. Several prospective randomized trials have demonstrated that concurrent delivery of chemotherapy and RT (CRT) is the most promising approach, given that locoregional recurrence is the leading pattern of failure for patients with locally advanced HNC. Induction chemotherapy before CRT has not been shown to be superior to CRT alone and the added toxicity may negatively impact the compliance with CRT. Sequential chemotherapy administration, in the form of induction chemotherapy followed by RT or CRT, has been successful as a strategy for organ preservation in patients with potentially resectable laryngeal and hypopharyngeal cancer. Systemic chemotherapy delivered concurrently with RT is used as a standard treatment for locally advanced HNC. Copyright © 2014 Elsevier Inc. All rights reserved.

Case reports have suggested that treatment with high-dose etoposide can result in development of a unique secondary leukemia. This study was designed to estimate the risk of developing leukemia for patients receiving conventional doses of etoposide along with cisplatin and bleomycin. We reviewed the records at Indiana University of all untreated patients entering clinical trials using etoposide at conventional doses (cumulative dose, 2000 mg/m2 or less) for germ cell cancer between 1982 and 1991. The records of all patients who received a chemotherapy regimen containing etoposide, ifosfamide, or cisplatin after failing to respond to primary chemotherapy were also reviewed. Between 1982 and 1991, 538 patients entered serial clinical trials with planned cumulative etoposide doses of 1500-2000 mg/m2 in combination with cisplatin plus either ifosfamide or bleomycin. Of these 538 patients, 348 received an etoposide combination as initial chemotherapy and 190 received etoposide as part of salvage treatment. To date, 315 patients are alive, with median follow-up of 4.9 years, and 337 patients have had follow-up beyond 2 years. Two patients (0.37%) developed leukemia. One developed acute undifferentiated leukemia with a t(4;11) (q21;q23) cytogenetic abnormality 2.0 years after starting etoposide-based therapy, and one developed acute myelomonoblastic leukemia with no chromosome abnormalities 2.3 years after beginning chemotherapy. During this period, several hundred patients were treated with etoposide-based chemotherapy and did not enter clinical trials. Three of these patients are known to have developed hematologic abnormalities, including one patient with acute monoblastic leukemia with a t(11;19)(q13;p13) abnormality. Secondary leukemia after treatment with a conventional dose of etoposide does occur, but the low incidence does not alter the risk-to-benefit ratio of etoposide-based chemotherapy in germ cell cancer. The reports of leukemia associated with high doses of etoposide emphasize the need for diligent follow-up of patients and make careful risk-to-benefit analysis imperative.

Abstract The prognosis of locally advanced (T3/T4 or N1) and metastatic disease urothelial carcinoma is poor. In this retrospective study, we reviewed data about patients receiving third-line chemotherapy for metastatic disease, in view of the lack of data in this setting. We retrospectively analyzed medical records of patients with a pathologic diagnosis of urothelial carcinoma treated with systemic chemotherapy for metastatic disease at 4 participating Institutions between January, 2010, and January, 2015. Cox proportional hazards regression was used to evaluate the association of the chemotherapy agent used versus others with overall survival, adjusted for 5 externally validated prognostic factors in advanced urothelial carcinoma. Of 182 patients that received first-line chemotherapy/adjuvant chemotherapy as defined above, 116 patients (63.73%) received second-line salvage treatment. Fifty-two patients were finally included in this analysis, whereas 9 were excluded due to missing data. Third-line chemotherapy was based on cyclophosphamide, platinum, vinflunine, taxanes, and gemcitabine in 16, 12, 11, 10, and 3 patients, respectively. Median PFS (progression-free survival) and OS (overall survival) of the population were 13 (10–17) and 31 (28–36) weeks. Single-agent cyclophosphamide was associated with a PFS of 18 (13–22) and an OS of 38 (33–41) weeks, whereas platinum-based combinations were associated with a PFS of 5 weeks and an OS of 8 weeks. Multivariate analysis showed improved survival in patients treated with cyclophosphamide (hazard ratio (HR) = 0.42; 95% CI: 0.20–0.89; P = 0.025) and a worse survival in those treated with platinum-based regimens (HR: 4.37; 95% CI = 1.95–9.77; P < 0.01). We observed a significantly longer overall survival in patients receiving single-agent cyclophosphamide, with few grade 3 to 4 toxicities. Further studies should assess the efficacy of metronomic single-agent cyclophosphamide in advanced lines of treatment, as it may yield a survival benefit with low costs and no detrimental effects on quality of life.

Zhang, Wenchao; Li, Jiawei; Li, Ran; Zhang, Ying; Han, Mingyong; Ma, Wei

This meta-analysis was conducted to investigate the efficacy and safety of 125 I brachytherapy for locally advanced non-small cell lung cancer (NSCLC). Trials comparing 125 I brachytherapy with chemotherapy in NSCLC were identified. Meta-analysis was performed to obtain pooled risk ratios for an overall response rate (ORR), disease control rate (DCR) and complications, and pooled hazard ratio for overall survival (OS). Fifteen studies including 1188 cases were included. The pooled result indicated that there were significant differences in ORR, DCR, and OS between 125 I brachytherapy combined with chemotherapy and chemotherapy alone, but no statistic differences in gastrointestinal symptoms, leukopenia, myelosuppression, and hemoglobin reduction. Patients treated with 125 I brachytherapy combined with chemotherapy have a higher relative risk of pneumothorax, bloody sputum, and pneumorrhagia compared with chemotherapy alone. Seeds migration only occurred in the group treated with 125 I brachytherapy. There were significant differences in ORR, DCR, and myelosuppression between 125 I brachytherapy alone and chemotherapy. 125 I brachytherapy combined with chemotherapy can significantly enhance the clinical efficacy and improve the OS of patients with advanced NSCLC without increasing the incidence of complications of chemotherapy. 125 I brachytherapy alone can significantly enhance the clinical efficacy and reduce the incidence of myelosuppression compared with chemotherapy. However, 125 I brachytherapy may cause lung injury. Large sample and higher-quality randomized controlled trials are needed to confirm the pooled results of complications.

Role of Chemotherapy and Targeted Therapy in Early-Stage Non-Small Cell Lung Cancer.

PubMed

Gadgeel, Shirish M

2017-01-01

On the basis of several randomized trials and meta-analyses, adjuvant chemotherapy is the accepted standard of care for certain patients with early-stage non-small cell lung cancer (NSCLC). Patients with stage II, IIIA, or large (≥ 4 cm) IB tumors are candidates for adjuvant chemotherapy. The survival improvement with adjuvant chemotherapy is approximately 5% at 5 years, though certain trials have suggested that it can be 8% to 10%. Neoadjuvant chemotherapy also has shown a survival advantage, though the volume of data with this approach is far less than that of adjuvant chemotherapy. The combination of cisplatin and vinorelbine is the most well-studied regimen, but current consensus is to use four cycles of any of the platinum-based chemotherapy regimens commonly used as front-line therapy for patients with advanced-stage NSCLC. Trials to define biomarkers that can predict benefit from adjuvant chemotherapy have not been successful, but results of other such trials are still awaited. On the basis of the benefit observed with targeted agents in patients with advanced-stage disease and driver genetic alterations in their tumors, ongoing trials are evaluating the utility of these targeted agents as adjuvant therapy. Similarly, clinical benefit observed with checkpoint inhibitors has prompted assessment of these drugs in patients with early-stage NSCLC. It is very likely, in the future, that factors other than the anatomy of the tumor will be used to select patients with early-stage NSCLC for systemic therapy and that the choice of systemic therapy will extend beyond platinum-based chemotherapy.

Studies have rarely compared health outcomes for patients with breast cancer at different treatment stages. The purpose of the study was to compare symptoms and quality of life among patients with breast carcinoma receiving target, chemotherapy, or combined therapy. A longitudinal study was carried out with 57 patients receiving chemotherapy, 30 receiving target therapy, and 34 receiving combined therapy. Data were collected before the start of treatment, at 4 weeks, and at 12 weeks following the start of treatment. Symptom severity and interference were assessed by the M. D. Anderson Symptom Inventory. The physical and mental components of quality of life (physical component score [PCS] and mental component score [MCS]) were assessed using SF-36. There were no significant differences in symptom severity and interference for patients in the 3 therapy groups. The PCSs did not differ significantly according to the therapy group but did decrease significantly after each treatment. Patients receiving target therapy had significantly higher MCSs than did patients receiving chemotherapy, but the MCSs did not differ significantly before and after the treatment. Patients with higher symptom severity and interference had worse PCS and MCS. Patients at all treatment groups had worse physical components quality of life after treatment as compared with before treatment. Patients receiving target therapy had better mental components of quality of life. The mental components of quality of life remained stable during treatment. Nurses should assess the patients' symptoms during treatment and provide timely intervention to optimize their quality of life.

New developments in chemotherapy of advanced breast cancer.

Anthracyclines and taxanes are the two most active classes of chemotherapy for the treatment of advanced breast cancer. Recent studies have investigated combination therapy including doxorubicin (Dox) and paclitaxel. The efficacy of this combination has been established in a phase III study conducted by ECOG, comparing Dox/paclitaxel versus Dox versus paclitaxel. The combination is superior to Dox or paclitaxel with respect to response rate and time to disease progression, indicating that the combination provides a new standard for the first line treatment of metastatic breast cancer [1]. Phase II studies using higher doses of Dox and using shorter infusions of paclitaxel have suggested the combination can be further optimized; Gianni reported a 94% objective response rate using Dox 60 mg/m2 followed by paclitaxel 175 mg/m2 given over three hours [2]. The more active regimens are associated with enhanced cardiotoxicity; this toxicity can be avoided, however, by limiting the exposure to doxorubicin. The newer regimens have now been moved into phase III studies. Future progress for this disease will depend on the introduction of new agents. Two novel drugs are currently being investigated in randomised phase III trials as potentiators of Dox and/or paclitaxel. One is a monoclonal antibody from Genentech (Herceptin, trastuzumab) directed at the HER-2/neu oncogene, which is overexpressed in > 25% of breast cancers [3]. Recent results indicate that Herceptin in combination with paclitaxel (or with a Dox plus cyclophosphamide regimen) induces a higher response rate (RR) and prolongs the time to disease progression when compared to chemotherapy alone. The second agent N,N-diethyl-2[4-(phenylmethyl)-phenoxy] ethanamine.HCl (DPPE, BMS-217380-01), when combined with Dox, was associated with a higher RR than previously observed with Dox alone [4]. A randomized trial of Dox versus Dox plus DPPE is ongoing. The possible mechanisms underlying chemo-potentiation by these agents are discussed. As new anthracycline/taxane combinations establish themselves in earlier stages of the disease, the need for effective, non-cross resistant salvage regimens will emerge.

Herbal medicine has been widely used in patients with advanced colorectal cancer in China, but its efficacy has not been confirmed. To evaluate the beneficial effect and safety on Chinese herbal medicine therapy for advanced stage colorectal cancer, and it's influence on the patients' quality of life. The following electronic databases were searched: BIOSIS Previews, Cochrane Controlled Trials Register, Medline EMBASE, Biological Abstracts, until Aug. 2011. Manual searching was performed on 16 types of Chinese journals which started from their respective first publication dates, as well as unpublished conference proceedings. No language restriction was applied. Randomized or quasi-randomised controlled trials on the treatment of advanced stage colorectal cancer by herbal medicines or herbal medicines combined with chemotherapy, regardless of blinding. The data were extracted independently by two reviewers. Methodological quality of the included in trials was assessed according to the following parameters: randomisation, allocation concealment, double blinding, and drop-out rates. A total of 20 randomised controlled trials with 1304 participants were identified. All the 20 trials compared the use of herbal medicines with chemotherapy and chemotherapy alone in the treatment of advanced stage colorectal cancers.Compared with chemotherapy alone, the use of Quxie capsule combined with chemotherapy could decrease mortality rate (RR 0.17, 95% CI 0.03 to 0.97); the use of Jianpi Jiedu formula, Xiaozheng formula and Yiqi Huoxue herbal medicine combined with chemotherapy respectively could improve 1-year survival rate significantly; the use of Xiaozheng Formula in conjunction with chemotherapy could improve 3-year survival rate. There were 10 herbal medicines showing benefit in improving quality of life. Herbal medicines did not show additional benefit in response rate or stability rate. No trials reported serious adverse effect from herbal medicine. Some herbal medicines combined chemotherapy compared with chemotherapy alone showed more beneficial effects in improving 1-year, 3-year survival and quality of life.

We firstly investigated the expression of Pokemon in patients with non-small cell lung cancer (NSCLC), then characterized the role of Pokemon in evaluating the response to combined cisplatin and paclitaxel chemotherapy and prognosis. In this study, 61 patients with previously untreated locally advanced or metastatic NSCLC were treated with a combination chemotherapy comprising cisplatin and paclitaxel. The correlation between serum expression of Pokemon and effectiveness of chemotherapy was assessed. The expression level of Pokemon in NSCLC patients was higher than that in healthy controls (p = 0.000), and was correlated with tumor size and TNM stage (p < 0.05). Kaplan-Meier analysis and Cox proportional hazard model demonstrated a poor response and shorter survival time in patients with pretreatment Pokemon levels in excess of 135.09 ng/ml compared to those with Pokemon levels below 135.09 ng/ml (p = 0.013). Pokemon ≥ 135.09 ng/ml was an independent risk factor for survival time in NSCLC patients undergoing combination chemotherapy (p = 0.018). The serum level of Pokemon correlated with efficacy of cisplatin and paclitaxel combination chemotherapy and survival time, which indicated that Pokemon may be a potentially useful biomarker for predicting treatment effectiveness of first-line chemotherapy and prognosis in NSCLC. © 2015 S.

A standard chemotherapy for recurrent/metastatic salivary gland cancers has not been established. Combination chemotherapy of carboplatin and paclitaxel should be evaluated as a treatment option. This study retrospectively reviewed salivary gland cancer patients who received combination chemotherapy of carboplatin and paclitaxel. The differences in objective responses and in the prognoses according to the different pathological diagnoses were evaluated. A total of 38 patients were enrolled in the study; of them, 18 had salivary duct carcinomas (SDCs), nine had adenoid cystic carcinomas (ACCs), and 11 had other pathological diagnoses. Objective responses were observed in 15 (39%) patients. The median progression-free survival (PFS) was 6.5 months, and the median overall survival (OS) was 26.5 months. ACC patients had relatively low response rates (9%), but there were no significant differences in PFS or OS compared to other sub-types. The treatment was well tolerated, with few adverse events. Salivary gland cancer patients showed a moderate clinical response to the combination chemotherapy of carboplatin and paclitaxel. The objective response rates differed according to the pathological diagnoses, but there were no significant differences in prognoses.

The development of reactive oxygen species (ROS)-responsive drug delivery and drug release has gradually attracted much attention in recent years as a promising therapeutic strategy. Singlet oxygen (1O2) as the major ROS species is widely used in photodynamic therapy (PDT) of cancer. In the present study, we introduce a combined treatment using ROS-sensitive thioketal (TK) linkage as a linker between upconversion nanoparticles (UNs)-based PDT and doxorubicin (DOX)-based chemotherapy. UNs can not only play a role in PDT, but can also be used as a nanocarrier for drug delivery of DOX. Moreover, the products of 1O2 during PDT are able to cleave TK linker inducing the release of DOX which can further achieve the goal of chemotherapy. By using this 1O2-responsive nanocarrier delivery system, DOX can easily reach the tumor site and be accumulated in the nuclei to effectively kill the cancer cells, and therefore decreasing the side effects of chemotherapy on the body. Thus, PDT also has the function of controlling drug release in this combination treatment strategy. Compared with monotherapy, the combination of PDT with chemotherapy also possesses excellent drug loading capability and anticancer efficiency.

The effect of chemotherapy on peritoneal carcinomatosis (PC) of gastric cancer remains unclear. Recently, the intraperitoneal (IP) administration of taxanes [e.g., paclitaxel (PTX) and docetaxel (DOC)] during the perioperative period has shown promising results. Herein, we summarized the rationale and methodology for using IP chemotherapy with taxanes and reviewed the clinical results. IP administered taxanes remain in the IP space at an extremely high concentration for 48-72 h. The drug directly infiltrates peritoneal metastatic nodules from the surface and then produces antitumor effects, making it ideal for IP chemotherapy. There are two types of perioperative IP chemotherapy with taxanes: neoadjuvant intraperitoneal and systemic chemotherapy and sequential perioperative intraperitoneal chemotherapy (SPIC). In SPIC, patients receive neoadjuvant IP chemotherapy and the same regimen of IP chemotherapy after cytoreductive surgery (CRS) until disease progression. Usually, a taxane dissolved in 500-1000 mL of saline at ordinary temperature is administered through an IP access port on an outpatient basis. According to phase I studies, the recommended doses (RD) are as follows: IP DOC, 45-60 mg/m(2); IP PTX [without intravenous (IV) PTX], 80 mg/m(2); and IP PTX (with IV PTX), 20 mg/m(2). Phase II studies have reported a median survival time of 14.4-24.6 mo with a 1-year overall survival of 67%-78%. A phase III study comparing S-1 in combination with IP and IV PTX to S-1 with IV cisplatin started in 2011. The prognosis of patients who underwent CRS was better than that of those who did not; however, this was partly due to selection bias. Although several phase II studies have shown promising results, a randomized controlled study is needed to validate the effectiveness of IP chemotherapy with taxanes for PC of gastric cancer.

Prevention of chemotherapy-induced nausea and vomiting (CINV) is crucial for maintaining the quality of life of cancer patients. Female patients have been underrepresented in previous clinical studies of aprepitant or palonosetron. We performed a prospective multicenter study to investigate the efficacy and safety of triple therapy comprising these two agents and dexamethasone in female cancer patients receiving chemotherapy that included cisplatin (≥ 50 mg/m(2)). Aprepitant was administered at a dose of 125 mg before chemotherapy on day 1 and at 80 mg on days 2 and 3. Palonosetron (0.75 mg) was given before chemotherapy on day 1. Dexamethasone was administered at a dose of 9.9 mg before chemotherapy on day 1 and at 6.6 mg on days 2-4. The primary endpoint was the the proportion of patients with a complete response (CR no vomiting and no use of rescue medication) throughout the overall period (0-120 h post-chemotherapy). Ninety-six women (median age 55 years) were enrolled. The overall CR rate was 54.2 %. CR was obtained during the acute phase (0-24 h post-chemotherapy) and the delayed phase (24-120 h post-chemotherapy) in 87.5 and 56.3 % of the patients, respectively. The most common adverse reactions were constipation and fatigue (reported by three patients each). Exhibition of a favorable overall CR rate over existing two-drug combinations suggests that the triple therapy regimen used in the present study is effective and tolerable in patients with gynecological malignancies receiving cisplatin-based chemotherapy. Female patients may have a higher risk of developing CINV.

Colorectal cancer patients on chemotherapy usually have elevated levels of inflammatory markers and experience numerous side effects from chemotherapy thereby leading to poor quality of life. Omega-3 fatty acid and microbial cell preparation (MCP) have been known to provide significant benefits in patients on chemotherapy. The aim of this study was to determine the effect of supplementation of omega-3 fatty acid and MCP in quality of life, chemotherapy side effects and inflammatory markers in colorectal cancer patients on chemotherapy. A double-blind randomized study was carried out with 140 colorectal cancer patients on chemotherapy. Subjects were separated into two groups to receive either placebo or MCP [30 billion colony-forming unit (CFUs) per sachet] at a dose of two sachets daily for 4 weeks, and omega-3 fatty acid at a dose of 2 g daily for 8 weeks. Outcomes measured were quality of life, side effects of chemotherapy and levels of inflammatory markers such as interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and C-reactive protein. The supplementation with MCP and omega-3 fatty acid improved the overall quality of life and alleviated certain side effects of chemotherapy. The supplementation with MCP and omega-3 fatty acid also managed to reduce the level of IL-6 (P = 0.002). There was a significant rise in the placebo group's serum TNF-α (P = 0.048) and IL-6 (P = 0.004). The combined supplementation with MCP and omega-3 fatty acid may improve quality of life, reduce certain inflammatory biomarkers and relieve certain side effects of chemotherapy in colorectal patients on chemotherapy. © 2017 John Wiley & Sons Australia, Ltd.

The purpose of this study was to confirm whether black and white women with endometrial cancer are equally tolerant of chemotherapy and identify factors that impact survival. A retrospective review of 169 black women and 982 white women with the International Federation of Gynecologists and Obstetricians stage III, stage IV, or recurrent endometrial carcinoma was performed. All patients received doxorubicin combined with cisplatin. Chemotherapy parameters that were reviewed included relative dose, relative time, and relative dose intensity. Treatment cycles > or =7 were defined as treatment completion. Although black patients were more likely to experience grades 3-4 anemia (20% vs 14%) and genitourinary (5% vs 1%) toxicity, and less likely to experience severe gastrointestinal toxicity (10% vs 17%), the overall incidence of grades 3-4 treatment-related chemotoxicity was the same between the 2 groups (82% vs 82%). There were no differences in the number of cycles received, relative dose (0.57 vs 0.58), relative time (0.77 vs 0.78), or relative dose intensity (0.76 vs 0.76) for black and white patients. Black patients with advanced stage or recurrent endometrial cancer, treated on 4 Gynecologic Oncology Group (GOG) protocols, had similar dose intensity and severe chemotherapy-related toxicity compared with white patients, suggesting that previously described racial disparities in survival among patients in GOG trials may have an novel etiology.

Abstract Multimodal therapy approaches, such as combining chemotherapy agents with cellular immunotherapy, suffers from potential drug-mediated toxicity to immune effector cells. Overcoming such toxic effects of anticancer cellular products is a potential critical barrier to the development of combined therapeutic approaches. We are evaluating an anticancer strategy that focuses on overcoming such a barrier by genetically engineering drug-resistant variants of immunocompetent cells, thereby allowing for the coadministration of cellular therapy with cytotoxic chemotherapy, a method we refer to as drug-resistant immunotherapy (DRI). The strategy relies on the use of cDNA sequences that confer drug resistance and recombinant lentiviral vectors to transfer nucleic acid sequences into immunocompetent cells. In the present study, we evaluated a DRI-based strategy that incorporates the immunocompetent cell line NK-92, which has intrinsic antitumor properties, genetically engineered to be resistant to both temozolomide and trimetrexate. These immune effector cells efficiently lysed neuroblastoma cell lines, which we show are also sensitive to both chemotherapy agents. The antitumor efficacy of the DRI strategy was demonstrated in vivo, whereby neuroblastoma-bearing NOD/SCID/γ-chain knockout (NSG) mice treated with dual drug-resistant NK-92 cell therapy followed by dual cytotoxic chemotherapy showed tumor regression and significantly enhanced survival compared with animals receiving either nonengineered cell-based therapy and chemotherapy, immunotherapy alone, or chemotherapy alone. These data show there is a benefit to using drug-resistant cellular therapy when combined with cytotoxic chemotherapy approaches. PMID:22397715

Objective: To observe the efficacy of the combination of chemotherapy and Ginseng Rg3 on advanced non-small cell lung cancer(NSCLC). Methods: In the multi-center, large-sample, randomized, double blind trial, 414 patients with Ⅲ-Ⅳ NSCLC were enrolled.199 were in the experimental group and 215 the control group. The patients in the experimental group were treated with the standard first-line chemotherapy combined with Ginseng Rg3. The patients in the control group were treated with the same chemotherapy combined with placebo. Median overall survival (OS), Karnofsky performance scale (KPS), Traditional Chinese Medicine (TCM) symptoms score and side effects of two groups were observed as main indexes. Results: The median OS were 12.03 months in the experimental group, which was significantly better than that in the control group (8.46 months, P <0.05). Hemoglobin and white blood cells were decreased after the first and second cycle of treatment in both groups. Both adverse events were significantly milder in the treatment group ( P <0.05). In addition, after two courses of treatment, the KPS of patients was 78.95±9.14 in the experimental group and 76.77±9.15 in the control group, while the TCM symptoms score was 2.45±1.73 in the experimental group and 2.92±2.06 in the control group, with significant difference ( P <0.05). Conclusions: Combination of TCM with Western medicine such as chemotherapy could prolong the survival of patients with advanced NSCLC. The combined therapy improved patients' symptoms and reduced chemotherapy induced myelosuppression.

We evaluated the efficacy and safety of M-VAC chemotherapy combined with mild hyperthermia, a new therapeutic strategy for advanced metastatic transitional cell carcinoma of the urothelium. The subjects were 12 patients diagnosed with advanced metastatic transitional cell carcinoma of the urothelium. For mild hyperthermia, the patients' oral temperature was elevated to about 38 degrees C by heating for 20 min and retaining the heat for 20 min with a far-infrared heater. The antitumor effect was evaluated according to the RECIST, while adverse drug reactions were assessed based on the NCI-CTC. The antitumor effect was rated as partial remission (PR) in 10 of the 12 patients and stable disease in 2 patients, with an efficacy rate of 83% (10/12). All 10 patients who had achieved PR received three courses of treatment. Of the 12 patients, 5 died during the observation period, with survival for 9-23 months (mean: 15.6 months). Adverse drug reactions included myelosuppression in all patients (Grade 3 in 4 patients, Grade 4 in 8), and gastrointestinal toxicity, such as nausea or vomiting, which was mild (Grade 0 in 2 patients, Grade 1 in 8, Grade 2 in 1, Grade 3 in 1). The results of the present study suggest that M-VAC chemotherapy combined with mild hyperthermia, which potentiates the anticancer effect and reduces adverse drug reactions such as gastrointestinal symptoms, is a useful and safe method for the treatment of advanced transitional cell carcinoma of the urothelium.

While the predictive value of programmed cell death ligand-1 (PD-L1) protein expression for immune checkpoint inhibitor therapy of lung cancer has been extensively studied, the impact of standard platinum-based chemotherapy on PD-L1 or programmed cell death-1 (PD-1) expression is unknown. The aim of this study was to determine the changes in PD-L1 expression of tumor cells (TC) and immune cells (IC), in PD-1 expression of IC, and in the amount of stromal mononuclear cell infiltration after platinum-based chemotherapy in patients with lung cancer. We determined the amount of stromal mononuclear cells and PD-L1/PD-1 expressions by immunohistochemistry in bronchoscopic biopsy samples including 20 adenocarcinomas (ADC), 15 squamous cell carcinomas (SCC), 2 other types of non-small cell lung cancer, and 4 small cell lung cancers together with their corresponding surgical resection tissues after platinum-based chemotherapy. PD-L1 expression of TC decreased in ten patients (24.4%) and increased in three patients (7.32%) after neoadjuvant chemotherapy (p = 0.051). The decrease in PD-L1 expression, however, was significant only in patients who received cisplatin-gemcitabine combination (p = 0.020), while in the carboplatin-paclitaxel group, no similar tendency could be observed (p = 0.432). There was no difference between ADC and SCC groups. Neither PD-1 expression nor the amount of stromal IC infiltration showed significant changes after chemotherapy. This is the first study, in which both PD-L1 and PD-1 expression were analyzed together with the amount of stromal IC infiltration in different histological subtypes of lung cancer before and after platinum-based chemotherapy. Our results confirm that chemotherapy decreases PD-L1 expression of TC in a subset of patients, therefore, rebiopsy and re-evaluation of PD-L1 expression may be necessary for the indication of immune checkpoint inhibitor therapy.

As the standard first-line treatment for advanced non-small cell lung cancer (NSCLC) with activating epidermal growth factor receptor (EGFR) mutation, EGFR-tyrosine kinase inhibitors (EGFR-TKIs) have significantly improved the median progression-free survival (PFS) up to 18.9 months. However, almost all patients eventually develop acquired resistance to EGFR-TKIs, which limits the first-line PFS. To overcome the resistance and improve overall survival, researchers have tried to identify the resistance mechanisms and develop new treatment strategies, among which a combination of EGFR-TKIs and cytotoxic chemotherapy is one of the hotspots. The data from preclinical and clinical studies on combined EGFR-TKIs and chemotherapy have shown very interesting results. Here, we reviewed the available preclinical and clinical studies on first-line EGFR-TKIs-chemotherapy combination in patients with advanced NSCLC harboring activating EGFR mutation, aiming to provide evidences for more potential choices and shed light on clinical treatment.

CONTEXT Accurate prediction of who will (or won’t) have high probability of survival benefit from standard treatments is fundamental for individualized cancer treatment strategies. OBJECTIVE To develop a predictor of response and survival from chemotherapy for newly diagnosed invasive breast cancer. DESIGN Development of different predictive signatures for resistance and response to neoadjuvant chemotherapy (stratified according to estrogen receptor (ER) status) from gene expression microarrays of newly diagnosed breast cancer (310 patients). Then prediction of breast cancer treatment-sensitivity using the combination of signatures for: 1) sensitivity to endocrine therapy, 2) chemo-resistance, and 3) chemo-sensitivity. Independent validation (198 patients) and comparison with other reported genomic predictors of chemotherapy response. SETTING Prospective multicenter study to develop and test genomic predictors for neoadjuvant chemotherapy. PATIENTS Newly diagnosed HER2-negative breast cancer treated with chemotherapy containing sequential taxane and anthracycline-based regimens then endocrine therapy (if hormone receptor-positive). MAIN OUTCOME MEASURES Distant relapse-free survival (DRFS) if predicted treatment-sensitive and absolute risk reduction (ARR, difference in DRFS of the two predicted groups) at median follow-up (3 years), and their 95% confidence intervals (CI). RESULTS Patients in the independent validation cohort (99% clinical Stage II–III) who were predicted to be treatment-sensitive (28% of total) had DRFS of 92% (CI 85–100) and survival benefit compared to others (absolute risk reduction (ARR) 18%; CI 6–28). Predictions were accurate if breast cancer was ER-positive (30% predicted sensitive, DRFS 97%, CI 91–100; ARR 11%, CI 0.1–21) or ER-negative (26% predicted sensitive, DRFS 83%, CI 68–100; ARR 26%, CI 4–28), and were significant in multivariate analysis after adjusting for relevant clinical-pathologic characteristics. Other genomic predictors showed paradoxically worse survival if predicted to be responsive to chemotherapy. CONCLUSION A genomic predictor combining ER status, predicted chemo-resistance, predicted chemo-sensitivity, and predicted endocrine sensitivity accurately identified patients with survival benefit following taxane-anthracycline chemotherapy.

Background Pathological response of breast cancer to chemotherapy is a prognostic indicator for long-term disease free and overall survival. Responses of locally advanced breast cancer in the neoadjuvant chemotherapy (NAC) settings are often variable, and the prediction of response is imperfect. The purpose of this study was to detect primary tumor responses early after the start of neoadjuvant chemotherapy using quantitative ultrasound (QUS), textural analysis and molecular features in patients with locally advanced breast cancer. Methods The study included ninety six patients treated with neoadjuvant chemotherapy. Breast tumors were scanned with a clinical ultrasound system prior to chemotherapy treatment, during the first, fourth and eighth week of treatment, and prior to surgery. Quantitative ultrasound parameters and scatterer-based features were calculated from ultrasound radio frequency (RF) data within tumor regions of interest. Additionally, texture features were extracted from QUS parametric maps. Prior to therapy, all patients underwent a core needle biopsy and histological subtypes and biomarker ER, PR, and HER2 status were determined. Patients were classified into three treatment response groups based on combination of clinical and pathological analyses: complete responders (CR), partial responders (PR), and non-responders (NR). Response classifications from QUS parameters, receptors status and pathological were compared. Discriminant analysis was performed on extracted parameters using a support vector machine classifier to categorize subjects into CR, PR, and NR groups at all scan times. Results Of the 96 patients, the number of CR, PR and NR patients were 21, 52, and 23, respectively. The best prediction of treatment response was achieved with the combination mean QUS values, texture and molecular features with accuracies of 78%, 86% and 83% at weeks 1, 4, and 8, after treatment respectively. Mean QUS parameters or clinical receptors status alone predicted the three response groups with accuracies less than 60% at all scan time points. Recurrence free survival (RFS) of response groups determined based on combined features followed similar trend as determined based on clinical and pathology. Conclusions This work demonstrates the potential of using QUS, texture and molecular features for predicting the response of primary breast tumors to chemotherapy early, and guiding the treatment planning of refractory patients.

Background Amuvatinib (MP-470) is a multi-targeted kinase inhibitor with potent activity against c-Kit, synergistic with DNA-damaging agents. We evaluated amuvatinib in combination with platinum-etoposide (EP) chemotherapy by objective response rate, survival, and tolerability in platinum-refractory small cell lung cancer (SCLC) patients. Methods This study used a Simon 2-stage design requiring ≥3 centrally confirmed responses in the first 21 subjects. Subjects received EP with 300 mg amuvatinib orally three times daily in cycles of 21 days. A three-day amuvatinib run-in period before EP occurred in Cycle 1. Subjects received the same EP chemotherapy regimen given prior to progression/relapse. Results Among 23 subjects treated, we observed four PRs (17.4%) per RECIST 1.1, only two of which were centrally confirmed (8.7%, response duration 119, 151 days). Three subjects (13%) had confirmed stable disease. c-Kit H-score was ≥100 in two subjects whose respective durations of disease control were 151 and 256 days. Conclusions The addition of amuvatinib to EP chemotherapy in unselected, platinum-refractory SCLC did not meet the primary endpoint of ≥3 confirmed responses in stage 1. However, high c-Kit expression in two subjects with durable disease control suggests the potential for further study of amuvatinib in SCLC patients with high c-Kit expression. PMID:29113403

Amuvatinib (MP-470) is a multi-targeted kinase inhibitor with potent activity against c-Kit, synergistic with DNA-damaging agents. We evaluated amuvatinib in combination with platinum-etoposide (EP) chemotherapy by objective response rate, survival, and tolerability in platinum-refractory small cell lung cancer (SCLC) patients. This study used a Simon 2-stage design requiring ≥3 centrally confirmed responses in the first 21 subjects. Subjects received EP with 300 mg amuvatinib orally three times daily in cycles of 21 days. A three-day amuvatinib run-in period before EP occurred in Cycle 1. Subjects received the same EP chemotherapy regimen given prior to progression/relapse. Among 23 subjects treated, we observed four PRs (17.4%) per RECIST 1.1, only two of which were centrally confirmed (8.7%, response duration 119, 151 days). Three subjects (13%) had confirmed stable disease. c-Kit H-score was ≥100 in two subjects whose respective durations of disease control were 151 and 256 days. The addition of amuvatinib to EP chemotherapy in unselected, platinum-refractory SCLC did not meet the primary endpoint of ≥3 confirmed responses in stage 1. However, high c-Kit expression in two subjects with durable disease control suggests the potential for further study of amuvatinib in SCLC patients with high c-Kit expression.

The objective was to evaluate response rate, response duration, and toxicity after systemic and intraventricular chemotherapy in primary CNS lymphoma (PCNSL).
 From September 1995 to September 1998, 20 consecutive patients with PCNSL (median age 64, range 27 to 71 years) were enrolled in a pilot study evaluating chemotherapy without radiotherapy. A high dose methotrexate (MTX) (cycles 1, 2, 4, 5) and cytarabine (ara-C) (cycles 3, 6) based systemic therapy (including dexamethasone, vinca alkaloids, ifosfamide, and cyclophosphamide) was combined with intraventricular MTX, prednisolone, and ara-C.
 Complete response was achieved in 11 and partial remission in two patients; in one response could not be determined. Four patients showed progressive disease and two (70, 71 years) died from treatment related complications. Observation time was 2 to 59 months (median 31.5 months). Kaplan-Meier estimate for median time to treatment failure (TTF) was 20.5 months, and for median survival 54 months. Systemic toxicity was mainly hematological. Ommaya reservoir infection occurred in four patients and acute transient MTX induced encephalopathy in two (subacute in another). Cognitive dysfunction possibly due to treatment was seen in only one patient after relapse and after a total of 12 cycles (six at relapse).
 In conclusion, primary chemotherapy based on high dose MTX and ara-C is highly efficient in PCNSL. Toxicity is manageable in patients younger than 70years.

To study the clinical value of combined detection of 4 tumor markers, namely lactic dehydrogenate (LDH), tissue polypeptide specific antigen (TPS), carcinoembryonic antigen (CEA) and beta2-microglobulin (beta2-MG) in patients with non-Hodgkin's lymphoma (NHL). The serum level of LDH was determined with automatic biochemical analyzer and TPS, CEA and beta2-MG levels were determined by enzyme-linked immumosorbent assay (ELISA) in 59 patients with NHL and 40 healthy adults. The levels of the 4 tumor markers were significantly higher in NHL patients than in the healthy control subjects (P<0.05). After chemotherapy, the serum levels of TPS and beta2-MG were significantly lowered in the patients who showed favorable response to the treatment (P<0.05), but the levels of LDH and CEA showed no significant change (P>0.05). The serum levels of LDH, TPS, CEA and beta2-MG in the patients in a stable or progressive phase did had no significant changes after chemotherapy (P>0.05). Combined detection of LDH, TPS, CEA and beta2-MG can be helpful to assist diagnosis of NHL and treatment evaluation.

The aim of this study was to evaluate the efficacy and toxicity of molecular targeted agents plus chemotherapy compared with chemotherapy alone as second-line therapy for patients with metastatic colorectal cancer (mCRC). We identified randomized controlled trials that compared molecular targeted agents plus chemotherapy with chemotherapy alone by searching the PubMed and Embase databases for articles published between January 2000 and September 2015. The outcome measures included progression-free survival, overall survival, objective response rate, and adverse events. Two investigators independently performed the information retrieval, screening, and data extraction. Stata 10.0 software was used to statistically analyze the extracted data. In accordance with our inclusion criteria, 11 trials, with a total of 7440 patients, were included in this meta-analysis through rounds of selection. We divided the biologic agents used into 3 subgroups based on the type of biologic agents-vascular endothelial growth factor (VEGF) inhibitor, epidermal growth factor receptor inhibitor, and other pathway inhibitors. Our results suggested that the regimen of a molecular targeted agent plus chemotherapy had a significant advantage in progression-free survival, overall survival, and objective response rate over chemotherapy alone (hazard ratio, 0.74; 95% confidence interval [CI], 0.70-0.78; hazard ratio, 0.88; 95% CI, 0.83-0.93; risk ratio, 2.24; 95% CI: 1.58-3.17, respectively). However, the rate of grade ≥ 3 adverse events was also higher in the combination therapy arm (risk ratio, 1.25; 95% CI, 1.17-1.33). Subgroup analysis showed that the combination of VEGF inhibitor with chemotherapy had a significant advantage in PFS, OS, and ORR over chemotherapy alone, but there was also a higher risk ratio in adverse events for this combination compared with the control group. In conclusion, a molecular targeted agent, especially VEGF inhibitor, plus chemotherapy is a worthwhile combination for patients with metastatic colorectal cancer as second-line therapy. However, more randomized controlled trials on a larger scale are needed for evaluating the value of epidermal growth factor receptor and other pathway inhibitors. Copyright © 2016 Elsevier Inc.

Purpose: To estimate the radiation equivalent of the chemotherapy contribution to observed complete response rates in published results of 1-phase radio-chemotherapy of muscle-invasive bladder cancer. Methods and Materials: A standard logistic dose–response curve was fitted to data from radiation therapy-alone trials and then used as the platform from which to quantify the chemotherapy contribution in 1-phase radio-chemotherapy trials. Two possible mechanisms of chemotherapy effect were assumed (1) a fixed radiation-independent contribution to local control; or (2) a fixed degree of chemotherapy-induced radiosensitization. A combination of both mechanisms was also considered. Results: The respective best-fit values of the independent chemotherapy-induced completemore » response (CCR) and radiosensitization (s) coefficients were 0.40 (95% confidence interval −0.07 to 0.87) and 1.30 (95% confidence interval 0.86-1.70). Independent chemotherapy effect was slightly favored by the analysis, and the derived CCR value was consistent with reports of pathologic complete response rates seen in neoadjuvant chemotherapy-alone treatments of muscle-invasive bladder cancer. The radiation equivalent of the CCR was 36.3 Gy. Conclusion: Although the data points in the analyzed radio-chemotherapy studies are widely dispersed (largely on account of the diverse range of chemotherapy schedules used), it is nonetheless possible to fit plausible-looking response curves. The methodology used here is based on a standard technique for analyzing dose-response in radiation therapy-alone studies and is capable of application to other mixed-modality treatment combinations involving radiation therapy.« less

Results of two phase 3 trials have shown first-line bevacizumab in combination with chemotherapy improves clinical outcomes in patients with advanced or recurrent non-squamous non-small-cell lung cancer (NSCLC). The SAiL (MO19390) study was undertaken to assess the safety and efficacy of first-line bevacizumab combined with standard chemotherapy regimens in clinical practice. Between August, 2006, and June, 2008, patients with untreated locally advanced, metastatic, or recurrent non-squamous NSCLC were recruited to this open-label, single group, phase 4 study from centres in 40 countries. Eligible patients had histologically or cytologically documented inoperable, locally advanced, metastatic, or recurrent disease (stage IIIB-IV); an Eastern Cooperative Oncology Group performance status of 0-2; and adequate haematological, hepatic, and renal function. Patients received bevacizumab (7.5 or 15 mg/kg every 3 weeks) plus standard chemotherapy for up to six cycles, followed by single-agent bevacizumab until disease progression. The primary endpoint was safety; analysis was by intention to treat (ITT). This study is registered with ClinicalTrials.gov, number NCT00451906. At the final data cutoff (July 24, 2009), an ITT population of 2212 patients was assessed. The incidence of clinically significant (grade > or = 3) adverse events of special interest was generally low; thromboembolism occurred in 172 (8%) patients, hypertension in 125 (6%), bleeding in 80 (4%), proteinuria in 67 (3%), and pulmonary haemorrhage in 15 (1%). 57 (3%) patients died because of these adverse events, with thromboembolism (26 patients, 1%) and bleeding (17, 1%) as the most common causes. The most common grade 3 or higher serious adverse events deemed by investigators to be associated with bevacizumab were pulmonary embolism (28 patients; 1%) and epistaxis, neutropenia, febrile neutropenia, and deep vein thrombosis (all of which occurred in 13 patients [1%]). Bevacizumab was temporarily interrupted after 28 (2%) of 1347 bleeding events and 72 (7%) of 1025 hypertension events, and permanently discontinued after 110 (8%) bleeding events and 40 (4%) hypertension events. No new safety signals were reported. Our results confirm the manageable safety profile of first-line bevacizumab in combination with various standard chemotherapy regimens for treatment of advanced non-squamous NSCLC.

Pleotropic-glycoprotein (P-gp)-mediated resistance is the usual cause of relapse in dogs with lymphoma. 1-(2-chloroethyl)3-cyclohexyl-1-nitrosurea (CCNU) and 5-(3,3-dimethyl-1-triazeno)-imidazole-4-carboxamide (DTIC) are alkylating agents that are not affected by P-gp and lack cross-resistance to each other. A combination protocol offers the advantage of improved summation dose and synergistic activity. A combination of CCNU and DTIC that is well tolerated can be used to treat dogs with lymphoma that developed resistance or failed to respond to previously administered chemotherapy. Fifty-seven dogs with lymphoma that were resistant to treatment with standard chemotherapy (L-CHOP; L-asparaginase, cyclophosphamide, doxorubicin, vincristine, prednisone). Prospective phase I and II trials were performed. CCNU was given PO immediately before a 5-h IV infusion of DTIC. Concurrent antiemetics and prophylactic antibiotics were used. Treatments were administered every 4 weeks. Based on the results of 8 dogs in the phase I study, CCNU at 40 mg/m(2) PO combined with DTIC at 600 mg/m(2) IV was used to treat 57 dogs with resistant lymphoma. Thirteen (23%) dogs had a complete response (CR) for a median of 83 days and 7 (12%) had a partial response for a median of 25 days. The median L-CHOP CR duration of the dogs that did not respond to CCNU-DTIC was significantly longer than that of the dogs that did achieve remission with CCNU-DTIC (225 days versus 92 days, P= .02). The principal toxic event was neutropenia; the median neutrophil count 7 days after treatment was 1,275 cells/microL. Increases in alanine transaminase activity, possibly associated with hepatotoxicity, were detected in 7 dogs. A combination of CCNU and DTIC can be an effective option to rescue dogs with resistant lymphoma.

Between January 1985 and July 1989 a total of thirty-eight patients with locally advanced pancreatic cancer were treated with high energy neutrons at Fermilab. Twenty-one patients received only neutrons and seventeen were given chemotherapy in addition, either concurrently or subsequently following the completion of neutron irradiation. This is a retrospective study. Data were analyzed for tolerance, complications and survival. Three of the twenty-one (14%) patients who received only neutron beam therapy developed Grade ID or greater complications in the RTOG/EORTC scale. The median survival was 6.4 months. One of these patients is alive 10 months post treatment. Of seventeen patientsmore » who also received chemotherapy, five (29%) had severe complications. However, median survival was 13.5 months. Four of these seventeen patients are still alive at the time of this analysis. The preliminary results show that there is improvement in the survival of patients treated with combined neutron irradiation and chemotherapy. A pilot study to further evaluate these results in a larger group of patients is underway. Details of complications and chemotherapy regimen will be preseqted.« less

Developing new methods for chemotherapy drug delivery has become a topic of great concern. Vinca alkaloids are among the most widely used chemotherapy reagents for tumor therapy; however, their side effects are particularly problematic for many medical doctors. To reduce the toxicity and enhance the therapeutic efficiency of vinca alkaloids, many researchers have developed strategies such as using liposome-entrapped drugs, chemical- or peptide-modified drugs, polymeric packaging drugs, and chemotherapy drug combinations. This review mainly focuses on the development of a vinca alkaloid drug delivery system and the combination therapy. Five vinca alkaloids (eg, vincristine, vinblastine, vinorelbine, vindesine, and vinflunine) are reviewed. PMID:25877096

Radiation dose escalation is limited by the high incidence of pulmonary and esophageal toxicity, leading to calls for the omission of elective nodal irradiation (ENI) and the willingness to use involved-field irradiation (IFI) in patients with nonsmall cell lung cancer (NSCLC). A total of 200 eligible patients with inoperable stage III NSCLC were treated with concurrent chemoradiotherapy and randomized into either an IFI or ENI arm. A total of 4 to 6 cycles of cisplatin-based chemotherapy were delivered, and concurrent radiotherapy was started after the second cycle of chemotherapy. Three-dimensional conformal radiotherapy was delivered in once-daily fractions of 1.8 to 2 Gy to 68 to 74 Gy for IFI or 60 to 64 Gy for ENI. Patients in the IFI arm achieved better overall response rate (90% vs. 79%, P = 0.032) and better 5-years local control rate (51% vs.36%, P = 0.032) than those in the ENI arm. The radiation pneumonitis rate in patients with IFI was lower than in patients with ENI (17% vs. 29%, P = 0.044), and similar trends appeared in the radiation esophagitis, myelosuppression, and radiation pericarditis between 2 study arms, although not significantly. The 1-, 2-, and 5-year survival rates were 60.4%, 25.6%, and 18.3% for the ENI arm and 69.9%, 39.4%, and 25.1% for the IFI arm, respectively. Only the 2-year survival rates were statistically significant (P = 0.048). IFI arm achieved better overall response and local control than ENI arm, and it allowed a dose of 68 to 74 Gy to be safely administered to patients with inoperable stage III NSCLC. Outcome improvement can be expected by conformal IFI combined with chemotherapy for stage III NSCLC.

There have been remarkable advances in the targeted treatment of advanced non-small cell lung cancer (NSCLC) over the past several years. Survival outcomes are steadily improving as management paradigms shift in the diagnosis and treatment of advanced NSCLC. Customizing treatment based on histology and molecular typing has become a standard of care in this era of targeted therapy. While new chemotherapeutic agents have proven effective, the pivotal role of platinum-based chemotherapy doublets has been confirmed. Maintenance chemotherapy has become an option, but who to employ it in remains unclear in the real-world setting. Efforts to overcome resistance to targeted agents are ongoing utilizing combination regimens of chemotherapy plus targeted agents, but optimizing combination strategies needs further exploration. This review highlights recent developments in novel chemotherapeutics and in chemotherapy strategies over the past two years. Despite advances in molecular medicine, there remains an essential role for chemotherapy in advanced NSCLC, even in the recent targeted therapy era.

Multiple primary malignancy is defined as two or more malignancies detected in an individual person. In particular, synchronous quintuple primary malignancy is extremely rare. A 52-year-old male with anal pain and intermittent blood-tinged stool was diagnosed with malignancies in the stomach, jejunum, ascending colon, transverse colon and rectum. He underwent a subtotal gastrectomy, segmental resection of the jejunum and total protocolectomy with end ileostomy. The postoperative pathologic findings were moderate differentiated gastric adenocarcinoma (pT1bN0M0, pStageIA), combined adenocarcinoma and neuroendocrine carcinoma of the jejunum (pT3N0M0, pStageIIA), three mucinous adenocarcinoma of the ascending colon (pT3N0M0, pStageIIA), transverse colon (pT1N0M0, pStageI) and rectum (pT3N1aM0, pStageIIIB). The tumors did not lack MLH-1 and MSH-2 expression, as the markers (bat26, D5S346, bat25, D2S123) suggest MSI-H presence. Adjuvant chemoradiotherapy was started according to regimen, FOLFOX 4 for advanced rectal cancer. Six years post-operation, the patient is currently attending regular follow-ups without recurrence or metastasis. PMID:28104993

To improve the complete remission (CR) rate of newly diagnosed acute myeloid leukemia (AML) patients and alleviate the severe side effects of double induction chemotherapy, we combined a standard regimen with granulocyte colony-stimulating factor (G-CSF) priming chemotherapy to compose a new double induction regimen for AML patients who failed to achieve CR after the first course. Ninety-seven patients with AML who did not achieve CR after the first course of standard chemotherapy were enrolled. Among them, 45 patients received G-CSF priming combined with low-dose chemotherapy during days 20-22 of the first course of chemotherapy, serving as priming group, 52 patients were administered standard chemotherapy again, serving as control group. Between the two groups there were no differences in the French-American-British (FAB) classification, risk status, the first course of chemotherapy, blood cell count or blasts percentage of bone marrow before the second course. But the CR rate was significantly higher and the adverse effect was much lower in the priming group than the control group. Cox multivariate regression analysis showed that WBC level before the second course and the selection of the second chemotherapy regimen were two independent factors for long survival of patients. These results elucidate that standard chemotherapy followed by G-CSF priming new double induction chemotherapy is an effective method for AML patients to improve CR rate and reduce adverse effects.

Esophageal symptoms are common during radiation and chemotherapy. It is unclear how often these symptoms persist after therapy. We retrospectively reviewed medical records of 320 adults treated for nonmetastatic breast cancer (84), lung cancer (109), or Hodgkin and non-Hodgkin lymphoma (127) who were disease-free at 10-14 months after therapy. Treatment included chemotherapy with or without nonmediastinal radiation therapy (150 patients), chemotherapy plus sequential mediastinal radiation therapy (MRT) (48 patients), chemotherapy plus concurrent MRT (61 patients), or non-MRT only (61 patients). Proton pump inhibitor use was documented. All treatment groups had similar prevalence of the esophageal symptom of heartburn before therapy. Rates were higher during treatment in those who received MRT with or without chemotherapy, but declined by 10-14 months after treatment. However, low baseline rates of dysphagia (4%) and odynophagia (2%) increased significantly after combined chemotherapy and MRT to 72% for dysphagia and 62% for odynophagia (P < 0.01) during treatment and stayed significantly elevated over baseline with 27% of the patients having dysphagia and 11% having odynophagia at 10-14 months after treatment. The use of proton pump inhibitors by patients who had MRT with chemotherapy was significantly increased during and after treatment (P = 0.002). Dysphagia, odynophagia and the use of proton pump inhibitors were significantly more common both during and after treatment than before treatment in patients who received both chemotherapy and mediastinal radiation. Our data highlight the important challenge for clinicians of managing patients with lung cancer and lymphoma who have persistent esophageal problems, particularly dysphagia and odynophagia, at approximately 1 year after treatment. © 2016 International Society for Diseases of the Esophagus.

Lung cancer is the leading cause of cancer-associated death world-wide. And the lung cancer is generally divided into small cell lung carcinoma and non-small cell lung cancer. For advanced NSCLC, the chemotherapy and target therapy were the important treatment modality. This meta-analysis was to evaluate the clinical efficacy and toxicity between endostar combined chemotherapy and chemotherapy alone in Chinese patients. We searched the PubMed, EMBASE, and CNKI databases to find the potential relevant articles reporting the endostar combined with chemotherapy regimen in the treatment of nonsmall cell lung cancer in Chinese patients. The tumor response and toxicity difference between the two groups were demonstrated by odds ratio (OR) and its 95% confidence interval (95% CI). All the data was pooled by Stata 11.0 (http://www.stata.com; Stata Corporation, College Station, TX) software. We included 14 studies published in Chinese or English studies. The pooled results showed adding endostar in the chemotherapy regimen can significant increase the objective response rate (OR = 2.42, 95% CI = 1.87-3.12, P = 0.00) and disease control rate (OR = 2.22, 95% CI = 1.68-2.94, P = 0.00). For toxicities, the pooled data showed no statistical difference for grade III-IV granulocytopenia risk (OR = 1.04, 95% CI = 0.74-1.44, P = 0.83). Nausea and vomiting (OR = 0.93 95% CI: 0.51-1.52, P = 0.78) and grade III-IV alopecia (OR = 0.99, 95% CI: 0.76-1.29, P = 0.95). The funnel plot showed no statistical publications. Combined treatment with endostar can improve the response rate for NSCLC patients without increasing the risk of developing severe adverse event.

Glioma Cell Death Induced by Irradiation or Alkylating Agent Chemotherapy Is Independent of the Intrinsic Ceramide Pathway

2013-01-01

Background/Aims Resistance to genotoxic therapy is a characteristic feature of glioma cells. Acid sphingomyelinase (ASM) hydrolyzes sphingomyelin to ceramide and glucosylceramide synthase (GCS) catalyzes ceramide metabolism. Increased ceramide levels have been suggested to enhance chemotherapy-induced death of cancer cells. Methods Microarray and clinical data for ASM and GCS in astrocytomas WHO grade II–IV were acquired from the Rembrandt database. Moreover, the glioblastoma database of the Cancer Genome Atlas network (TCGA) was used for survival data of glioblastoma patients. For in vitro studies, increases in ceramide levels were achieved either by ASM overexpression or by the GCS inhibitor DL-threo-1-phenyl-2-palmitoylamino-3-morpholino-1-propanol (PPMP) in human glioma cell lines. Combinations of alkylating chemotherapy or irradiation and ASM overexpression, PPMP or exogenous ceramide were applied in parental cells. The anti-glioma effects were investigated by assessing proliferation, metabolic activity, viability and clonogenicity. Finally, viability and clonogenicity were assessed in temozolomide (TMZ)-resistant cells upon treatment with PPMP, exogenous ceramide, alkylating chemotherapy, irradiation or their combinations. Results Interrogations from the Rembrandt and TCGA database showed a better survival of glioblastoma patients with low expression of ASM or GCS. ASM overexpression or PPMP treatment alone led to ceramide accumulation but did not enhance the anti-glioma activity of alkylating chemotherapy or irradiation. PPMP or exogenous ceramide induced acute cytotoxicity in glioblastoma cells. Combined treatments with chemotherapy or irradiation led to additive, but not synergistic effects. Finally, no synergy was found when TMZ-resistant cells were treated with exogenous ceramide or PPMP alone or in combination with TMZ or irradiation. Conclusion Modulation of intrinsic glioma cell ceramide levels by ASM overexpression or GCS inhibition does not enhance the anti-glioma activity of alkylating chemotherapy or irradiation.

Renal cell carcinoma (RCC) is a heterogeneous disease with regards to histology, progression, and response to treatment. Cytotoxic chemotherapy has been extensively studied in metastatic RCC (mRCC). Responses in most studies are modest and the mechanisms of resistance remain poorly understood. Targeted therapies have significantly improved outcomes in mRCC; however, most patients eventually relapse and die of their disease. Early clinical data suggest that combinations of chemotherapy and targeted agents are clinically active and are well tolerated. We reviewed the available literature for published clinical trials incorporating traditional chemotherapeutic agents in the treatment of mRCC. These papers were identified through a Medline search and were included if they employed at least one chemotherapeutic agent in the treatment of mRCC. The literature was also reviewed for information regarding mechanisms of chemotherapy resistance. The data regarding the use of cytotoxic chemotherapy in mRCC consist of small, non-randomized phase I and II studies. The major response proportions with single agent chemotherapies are low but combination regimens either with other cytotoxic agents, cytokines, or targeted agents have demonstrated moderate activity. Disparate trial designs and lack of head to head clinical trials make it difficult to compare the efficacy of chemotherapy with that of immunotherapy or targeted agents. Chemotherapy is particularly useful in patients with collecting duct histology and predominantly sarcomatoid differentiation. Chemotherapy resistance may be mediated by overexpression of p-glycoprotein efflux pumps and the dysregulation of the microtubule-hypoxia inducible factor signaling axis. The role of cytotoxic chemotherapy in the treatment for clear cell RCC remains poorly defined. Cytotoxic chemotherapy is considered a standard of care in patients with mRCC with predominantly sarcomatoid differentiation and collecting duct RCC variants (Motzer et al., 2014). Early trials combining chemotherapy with targeted therapies are generally well tolerated and show clinical activity. A better understanding of the biology of aggressive subsets of RCC and mechanisms of resistance will help elucidate the role of cytotoxic agents in the current treatment paradigm of RCC.

To evaluate three methods for treating adult laryngeal hemangiomas: conventional chemotherapy, CO 2 laser combined with chemotherapy, and KTP laser. And to identify risk factors that affected the prognosis of the lesions. A retrospective analysis was performed on the data from patients with adult laryngeal hemangiomas treated by one of three aforementioned methods, the curative efficacy, and safety of those methods was compared. All cases were confirmed by suspension micro-laryngoscope examination. Pre- and post-treatment clinical photographs were taken and the outcomes were graded. Thirty-eight patients in 48 different cases were enrolled in the study between June 2010 and June 2016, and some patients were treated more than once. The treatment efficacy of the KTP laser was higher than that of chemotherapy according to the Kruskal-Wallis ANOVA test; however, the ordinal logistic regression showed that the choice of surgical procedure did not affect the treatment results; only the size of the bases of the lesions affected the prognosis of adult laryngeal hemangiomas. Pingyangmycin injection, KTP laser, and CO 2 laser combined with chemotherapy are safe and effective methods for the treatment of adult laryngeal hemangiomas. The size of base of the lesion affects the prognosis of the hemangiomas.

Cancer, referred to as the 'disease of civilization', continues to haunt humanity due to its dreadful manifestations and limited success of therapeutic interventions such as chemotherapy in curing the disease. Although effective, chemotherapy has repeatedly demonstrated inadequacy in disease management due to its debilitating side effects arising from its deleterious nonspecific effects on normal healthy cells. In addition, development of chemoresistance due to mono-targeting often results in cessation of chemotherapy. This urgently demands development and implementation of multitargeted alternative therapies with mild or no side effects. One extremely promising strategy that yet remains untapped in the clinic is augmenting chemotherapy with dietary phytochemicals or extracts. Ginger, depository of numerous bioactive molecules, not only targets cancer cells but can also mitigate chemotherapy-associated side effects. Consequently, combination therapy involving ginger extract and chemotherapeutic agents may offer the advantage of being efficacious with reduced toxicity. Here we discuss the remarkable and often overlooked potential of ginger extract to manage cancer, the possibility of developing ginger-based combinational therapies, and the major roadblocks along with strategies to overcome them in clinical translation of such inventions. We are optimistic that clinical implementation of such combination regimens would be a much sought after modality in cancer management. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Hatton, M Q; Reed, N S

The role of chemotherapy in malignant neuroendocrine tumours is difficult to assess because of their rarity and variation in biological behaviour. We present a retrospective review of chemotherapy given to 18 patients with metastatic and one with locally advanced neuroendocrine tumours. There were eight poorly differentiated neuroendocrine tumours, six thyroid medullary carcinomas, two phaeochromocytomas, two pancreatic islet cell tumours and one undifferentiated neuroblastoma. Four patients were given 3-weekly dacarbazine, vincristine and cyclophosphamide (DOC) chemotherapy. In eight patients, this regimen was modified by substituting the dacarbazine and cisplatin and etoposide (OPEC). A further six patients were treated with dacarbazine reintroduced into the 3-weekly regimen (DOPEC). The remaining patient received cisplatin and etoposide. There were two complete responses (both with OPEC) and eight partial responses (two with DOC, three with OPEC and three with DOPEC). Five patients had stable disease and four progressed. Four received further chemotherapy on relapse, producing one complete and one partial response. The median response duration to initial chemotherapy was 10 months (range 3-34). The median survival was 12 months (range 1-42). The main toxicity was haematological, with grade 3-4 neutropenia in 12 patients; eight suffered episodes of sepsis. One death was treatment related. Other toxicity was mild although three patients discontinued vincristine with grade 2 neurotoxicity. The response rate and side effects of these three regimens appear comparable. We conclude that, although these patient numbers are small, combination chemotherapy produces an encouraging response rate (53%; 95% CI 30-75) in malignant neuroendocrine tumours, with acceptable toxicity.

Purpose Colorectal cancer predominantly occurs in the elderly, but approximately 5% of patients are 50 years old or younger. We sought to determine whether young age is prognostic, or whether it influences efficacy/toxicity of chemotherapy, in patients with advanced disease. Methods We analyzed individual data on 6,284 patients from nine phase III trials of advanced colorectal cancer (aCRC) that used fluorouracil-based single-agent and combination chemotherapy. End points included progression-free survival (PFS), overall survival (OS), response rate (RR), and grade 3 or worse adverse events. Stratified Cox and adjusted logistic-regression models were used to test for age effects and age-treatment interactions. Results A total of 793 patients (13%) were younger than 50 years old; 188 of these patients (3% of total patients) were younger than 40 years old. Grade 3 or worse nausea (10% v 7%; P = .01) was more common, and severe diarrhea (11% v 14%; P = .001) and neutropenia (23% v 26%; P < .001) were less common in young (younger than 50 years) than in older (older than 50 years) patients. Age was prognostic for PFS, with poorer outcomes occurring in those younger than 50 years (median, 6.0 v 7.5 months; hazard ratio, 1.10; P = .02), but it did not affect RR or OS. In the subset of monotherapy versus combination chemotherapy trials, the relative benefits of multiagent chemotherapy were similar for young and older patients. Results were comparable when utilizing an age cut point of 40 years. Conclusion Young age is modestly associated with poorer PFS but not OS or RR in treated patients with aCRC, and young patients have more nausea but less diarrhea and neutropenia with chemotherapy in general. Young versus older patients derive the same benefits from combination chemotherapy. Absent results of a clinical trial, standard combination chemotherapy approaches are appropriate for young patients with aCRC. PMID:21646604

Toll-like receptors in the pathogenesis of chemotherapy-induced gastrointestinal toxicity.

PubMed

Cario, Elke

2016-06-01

Intestinal mucositis represents a common complication and dose-limiting toxicity of cancer chemotherapy. So far chemotherapy-induced intestinal mucositis remains poorly treatable resulting in significant morbidity and reduced quality of life in cancer patients. This review discusses recent insights into the pathophysiology of chemotherapy-induced intestinal mucositis. Novel mechanisms linking gut microbiota, host innate immunity and anticancer drug metabolism are highlighted. Gut microbiota may affect xenobiotic metabolism by direct and indirect mechanisms, critically modulating gut toxicity of chemotherapy drugs. Composition and metabolic function of the gut microbiome as well as innate immune responses of the intestinal mucosa are severely altered during chemotherapy. Commensal-mediated innate immune signaling via Toll-like receptors (TLRs) ambiguously shapes chemotherapy-induced genotoxic damage in the gastrointestinal tract. TLR2 may accelerate host detoxification by activating the multidrug transporter ATP-binding cassette 1 (ABCB1)/MDR1 P-glycoprotein to efflux harmful drugs, thus controlling the severity of cancer therapy-induced mucosal damage in the gastrointestinal tract. In contrast, selective chemotherapy drugs may drive LPS hyperresponsiveness via TLR4, which exacerbates mucosal injury through aberrant cytokine storms. Broad-spectrum antibiotic treatment does not seem to represent a valid therapeutic option, as drastic reduction in global gut microbiota may enhance risk of gastrointestinal toxicity and reduce efficacy of some chemotherapy drugs, at least in murine models. Several variables (environment, metabolism, dysbiosis, infections and/or genetics) influence the outcome of mucosal TLR signaling during cancer treatment. Differences in innate immune responses also reflect chemotherapy drug-specific effects. Future studies must investigate in more detail whether manipulating the delicate balance between gut microbiota and host immune responses by either monotherapy or combinations of different TLR agonists and antagonists may be indeed useful to limit the toxic side-effects of complex chemotherapy regimens, accelerate mucosal tissue regeneration and improve the anticancer treatment response.

A considerable amount of experimental and clinical data prove the cytoprotective effect of amifostine on normal tissue exposed to different types of antineoplastic treatments. The present study examines its influence on the short-term toxicity of either radiotherapy alone or combined radio-chemotherapy in patients with advanced head and neck cancer. Twenty-three patients with advanced head and neck cancer, mainly Stage III and IV, were treated with preoperative radiation (n = 1), pre- as well as postoperative radiotherapy (n = 5), postoperative radiation (n = 9) or combined postoperative radio-chemotherapy (n = 6). Before each radiation application a total dose of 500 mg amifostine was administered intravenously over 15 minutes. The documentation of this unselected patient group was compared retrospectively to a historical control group comprising 17 patients. In 15 patients (65%) of the amifostine group, therapy induced side effects such as mucositis and dermatitis of WHO Grade < or = 2 were detected, requiring interruptions of the radiotherapy (mean: 6.5, maximum 17 days). No mucosa or dermatologic toxicity of WHO Grade 3 or 4 was observed in this group. Significantly more acute toxicity was detected in the historical control group. Stomatitis or epitheliolysis of WHO Grade 3 occurred in 7 patients (41%). The side effects induced by the antineoplastic therapy caused an interruption of treatment in 15 patients (88%) (mean: 16, maximum 40 days; p = 0.0016). The application of amifostine before each radiation treatment seems to result in a distinct reduction of short-term toxicity of radiotherapy or combined radio-chemotherapy in patients with head and neck cancer, allowing for a better adherence to the planned radiation time schedule.

To the present tense finally mine-out not tactic of treatment of patients with the cervical cancer (CC) of IIB stage, but in the standards of diagnostics and treatment there are different variants of treatment of this pathology, and choice, most optimum, as a rule, depends on subjective opinion of doctor. Consequently, purpose of our work--to promote efficiency of treatment of patients on CC IIB the stage, by application of neoadjuvant chemotherapy in the combined treatment. The results of treatment are analysed 291 patients on CC IIB stages which got radical treatment in Ivano-Frankivsk OKOD from 1998 to 2013 years. At the use of neoadjuvant chemotherapy index of general 5-years-survival and nonrecurrence survivability made 74.4% and 70.8%, and to preoperative chemotherapy--70.8% and 68.3% accordingly. At application of independent chemoradial therapy, to the index of general 5-years-survival and nonrecurrence survivability was 51.1% and 49.3%, accordingly. It is not exposed reliable difference (P < 0.05) at comparison of indexes of 5-years-survivability of patients which have got the combined methods of treatment, but a reliable difference is exposed when compared to patients which have got independent chemoradial therapy (P > 0.05). Consequently, application of the combined methods of treatment of patients of CC IIB stages were improved by indexes general 5-years and to nonrecurrence survivability by comparison to independent cheradial therapy. .

Here, we report a 54-year-old man diagnosed with type 3 advanced gastric cancer who underwent a total gastrectomy and splenectomy plus D2 lymphadenectomy. The pathologic diagnosis was Stage Ⅳ (T3N0H0P0CY1M1). Sixteen courses of combined S-1/CPT-11 chemotherapy were completed, at which time the CPT-11 was discontinued because of malaise, and S-1 alone was continued for a year. The patient is well and has been recurrence-free for 7 years. Thus, he is considered a long- term survivor who was treated with combination S-1/CPT-11 chemotherapy.

Chemotherapy-induced alopecia is a common and distressing adverse effect. In previous studies of scalp cooling to prevent chemotherapy-induced alopecia, conclusions have been limited. To evaluate whether use of a scalp cooling system is associated with a lower amount of hair loss among women receiving specific chemotherapy regimens for early-stage breast cancer and to assess related changes in quality of life. A prospective cohort study conducted at 5 US medical centers of women with stage I or II breast cancer receiving adjuvant or neoadjuvant chemotherapy regimens excluding sequential or combination anthracycline and taxane (106 patients in the scalp cooling group and 16 in the control group; 14 matched by both age and chemotherapy regimen). The study was conducted between August 2013 and October 2014 with ongoing annual follow-up for 5 years. Use of a scalp cooling system. Scalp cooling was initiated 30 minutes prior to each chemotherapy cycle, with scalp temperature maintained at 3°C (37°F) throughout chemotherapy and for 90 minutes to 120 minutes afterward. Self-estimated hair loss using the Dean scale was assessed 4 weeks after the last dose of chemotherapy by unblinded patient review of 5 photographs. A Dean scale score of 0 to 2 (≤50% hair loss) was defined as treatment success. A positive association between scalp cooling and reduced risk of hair loss would be demonstrated if 50% or more of patients in the scalp cooling group achieved treatment success, with the lower bound of the 95% CI greater than 40% of the success proportion. Quality of life was assessed at baseline, at the start of the last chemotherapy cycle, and 1 month later. Median follow-up was 29.5 months. Among the 122 patients in the study, the mean age was 53 years (range, 28-77 years); 77.0% were white, 9.0% were black, and 10.7% were Asian; and the mean duration of chemotherapy was 2.3 months (median, 2.1 months). No participants in the scalp cooling group received anthracyclines. Hair loss of 50% or less (Dean score of 0-2) was seen in 67 of 101 patients (66.3%; 95% CI, 56.2%-75.4%) evaluable for alopecia in the scalp cooling group vs 0 of 16 patients (0%) in the control group (P < .001). Three of 5 quality-of-life measures were significantly better 1 month after the end of chemotherapy in the scalp cooling group. Of patients who underwent scalp cooling, 27.3% (95% CI, 18.0%-36.6%) reported feeling less physically attractive compared with 56.3% (95% CI, 31.9%-80.6%) of patients in the control group (P = .02). Of the 106 patients in the scalp cooling group, 4 (3.8%) experienced the adverse event of mild headache and 3 (2.8%) discontinued scalp cooling due to feeling cold. Among women undergoing non-anthracycline-based adjuvant chemotherapy for early-stage breast cancer, the use of scalp cooling vs no scalp cooling was associated with less hair loss at 4 weeks after the last dose of chemotherapy. Further research is needed to assess outcomes after patients receive anthracycline regimens, longer-term measures of alopecia, and adverse effects. clinicaltrials.gov Identifier: NCT01831024.

Background: Triple-negative breast cancers (TNBC) are heterogeneous cancers with poor prognosis. We aimed to determine the clinical relevance of membrane type-4 matrix metalloproteinase (MT4-MMP), a membrane type matrix metalloproteinase that interacts with epidermal growth factor receptor (EGFR) overexpressed in >50% of TNBC. Methods: We conducted a retrospective immunohistochemical analysis on human TNBC samples (n=81) and validated our findings in in vitro and in vivo assays. Results: Membrane type-4 matrix metalloproteinase and EGFR are produced in 72.5% of TNBC samples, whereas those proteins are faintly produced by healthy tissues. Unexpectedly, tumour relapse after chemotherapy was reduced in samples highly positive for MT4-MMP. Mechanistically, this is ascribed to a higher sensitivity of MT4-MMP-producing cells to alkylating or intercalating chemotherapeutic agents, as assessed in vitro. In sharp contrast, MT4-MMP expression did not affect tumour cell sensitivity to paclitaxel that interferes with protease trafficking. Importantly, MT4-MMP expression sensitised cancer cells to erlotinib, a tyrosine kinase EGFR inhibitor. In a pre-clinical model, the growth of MT4-MMP overexpressing xenografts, but not of control ones, was reduced by epirubicin or erlotinib. The combination of suboptimal drug doses blocked drastically the growth of MT4-MMP-producing tumours. Conclusions: We demonstrate that MT4-MMP defines a sub-population of TNBC sensitive to a combination of DNA-targeting chemotherapeutic agents and anti-EGFR drugs. PMID:28196064

Diagnosis and management of myeloma in the very elderly patient is challenging. Treatment options have vastly improved for elderly myeloma patients but still require the clinician to personalize therapy. In this paper, we offer evidence-based, pragmatic advice on how to overcome six of the main challenges likely to arise: 1) diagnosis of myeloma in this age group, 2) assessment of the need for treatment, and the fitness for combination chemotherapy, 3) provision of the best quality of supportive care, 4) choice of combination chemotherapy in those fit enough for it, 5) treatment of relapsed myeloma, and 6) provision of end of life care. With an increased burden of comorbidities and a reduced resilience to treatment and its associated toxicities, the management of myeloma in this age group requires a different approach to that in younger patients to maximize both quality and length of life.

Background The human IgG4 monoclonal antibody nivolumab targets programmed cell death-1 (PD-1) and promotes antitumor response by blocking the interaction of PD-1 with its ligands. This single-center phase Ib study investigated the tolerability, safety, and pharmacokinetics of nivolumab combined with standard chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC). Patients and methods Patients who had stage IIIB without indication for definitive radiotherapy, stage IV, or recurrent NSCLC were eligible. Regimens were nivolumab 10 mg/kg + gemcitabine/cisplatin (arm A), pemetrexed/cisplatin (arm B), paclitaxel/carboplatin/bevacizumab (arm C), or docetaxel (arm D). Regimens A, B, and D were repeated every 3 weeks for up to four cycles and regimen C was repeated for up to six cycles; nivolumab alone (arm A), with pemetrexed (arm B), bevacizumab (arm C), or docetaxel (arm D) was continued every 3 weeks as maintenance therapy until disease progression or unacceptable toxicity. Dose-limiting toxicity (DLT) was evaluated during the first treatment cycle. Results As of March 2014, six patients were enrolled in each arm. The combination of nivolumab 10 mg/kg and chemotherapy was well tolerated. DLT was observed in only one patient in arm A (alanine aminotransferase increased). Select adverse events (those with a potential immunologic cause) of any grade were observed in six, four, six, and five patients in arms A, B, C, and D, respectively. Three, three, six, and one patient achieved partial response while median progression-free survival was 6.28, 9.63 months, not reached, and 3.15 months in arms A, B, C, and D, respectively. Conclusions Combination of nivolumab 10 mg/kg and chemotherapy showed an acceptable toxicity profile and encouraging antitumor activity in patients with advanced NSCLC.

The purpose of this work was to determine the response rate and toxicity of a combination of Carmustine and Cisplatin administered before radiation in patients with newly diagnosed high grade astrocytoma. A good response rate has been published with this association in primary cerebral high grade tumor. This protocol was administered in a homogeneous population of 37 adult patients with measurable tumor on magnetic resonance imaging (MRI) or CT scan. After biopsy or subtotal resection, the patients received BCNU 40 mg/m2/d and CODP 40 mg/m2/d, for 3 days every 28 days for 3 cycles. Evaluation was performed before each cycle. Radiation therapy began 4 weeks after completing the chemotherapy or immediately if there was evidence of tumor progression on chemotherapy. Seven out of 37 (19%) demonstrated tumor regression with a median duration to progression of 11 months. Median survival was 6 months. Myelosuppression was the predominant but manageable toxicity. This work indicated that the first chemotherapy protocol gave poor results in a homogeneous group of patients, with bad prognosis.

The purpose of this study was to clarify the efficacy and toxicities of re-irradiation using proton beam therapy combined with weekly intra-arterial chemotherapy for recurrent oral cancer. Between October 2009 and July 2014, 34 patients who had recurrent oral cancer were treated by proton beam therapy combined with intra-arterial infusion chemotherapy at the Southern Tohoku Proton Therapy Center, Japan. For all patients, the median follow-up was 25 months (range, 3-77 months). After treatment, 22 patients (65%) achieved a complete response, and 12 patients (35%) achieved a partial response at the primary tumor site. One-year and 2-year overall survival (OS) rates were 62% and 42%, respectively. One-year and 2-year LC rates were 77% and 60%, respectively. No treatment-related deaths were observed during the treatment and follow-up periods. Re-irradiation using proton beam therapy combined with weekly intra-arterial chemotherapy improved OS and local control rates compared with other treatment modalities and could become a new treatment modality for patients with recurrent oral cancer. © 2016 John Wiley & Sons Australia, Ltd.

Literature describing medical treatment of canine prostatic carcinoma (PC) is sparse. The aims of this study were to assess outcomes, including time to progression (TTP) and median survival time (MST), of canine PC treated with non-steroidal anti-inflammatory drugs (NSAIDs) and/or chemotherapy, and to identify prognostic factors. Records from 8 institutions were searched for dogs with cytologically or histologically confirmed PC without bladder involvement: 67 dogs were included. Presenting signs were urinary (25), gastrointestinal ([GI], 11) and systemic (3); 16 dogs had GI and urinary signs, 7 dogs had systemic signs with concurrent GI or urinary signs and in 5 dogs the tumour was an incidental finding. Out of 27 dogs, 9 (33%) had positive urine culture. Metastases were identified in 26 dogs to lymph nodes (19), lungs (10), bone (2) and liver (1). Treatment included NSAIDs and chemotherapy (32), NSAIDs alone (31) and chemotherapy alone (4). The overall MST was 82 days (range 9-752) and median TTP was 63 days (range 9-752). Dogs receiving NSAIDs combined with chemotherapy experienced a significantly longer MST (106 vs 51 days; P = .035) and TTP (76 vs 44 days; P = .02) compared to dogs receiving NSAIDs alone. Intact dogs and those with metastatic disease had significantly shorter MST (31 vs 90 days, P = .018 and 49 vs 109 days, P = .037, respectively); intact dogs also had significantly shorter TTP (25 vs 63 days, P = .0003). This study suggests that a combination of NSAIDs and chemotherapy may improve outcomes in canine PC.

The purpose of this study is to assess the efficacy of moxibustion as a treatment of chemotherapy-induced leukopenia. Twelve databases were searched from their inception through June 2014, without a language restriction. Randomized clinical trials (RCTs) were included if moxibustion was used as the sole treatment or as a part of a combination therapy with conventional drugs for leukopenia induced by chemotherapy. Cochrane criteria were used to assess the risk of bias. Six RCTs with a total of 681 patients met our inclusion criteria. All of the included RCTs were associated with a high risk of bias. The trials included patients with various types of cancer receiving ongoing chemotherapy or after chemotherapy. The results of two RCTs suggested the effectiveness of moxibustion combined with chemotherapy vs. chemotherapy alone. In four RCTs, moxibustion was more effective than conventional drug therapy. Six RCTs showed that moxibustion was more effective than various types of control interventions in increasing white blood cell counts. There is low level of evidence based on these six trials that demonstrates the superiority of moxibustion over drug therapies in the treatment of chemotherapy-induced leukopenia. However, the number of trials, the total sample size, and the methodological quality are too low to draw firm conclusions. Future RCTs appear to be warranted.

To review recent studies in esophagogastric cancer. Positive emission tomography (PET) scan in follow-up after curative treatment of esophagogastric cancer did not lead to improved survival. In the preoperative treatment of esophagogastric cancer, the addition of the antivascular endothelial growth factor agent bevacizumab to perioperative chemotherapy with combination epirubicin, cisplatinum, and 5-fluorouracil (5-FU; ECF) failed to improve survival compared with chemotherapy alone. In a head-to-head comparison of preoperative chemotherapy for locally advanced gastric and esophagogastric adenocarcinoma, FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) significantly improved overall survival compared with ECF. Assessing response to induction chemotherapy prior to combined preoperative chemoradiotherapy in PET nonresponding patients allowed a change in chemotherapy during subsequent radiotherapy with improved rates of pathologic complete response. In human epidermal growth factor receptor-2-positive advanced esophagogastric adenocarcinoma, second-line treatment with the chemotherapy/trastuzumab drug conjugate emtansine/trastuzumab failed to improve response or overall survival compared with treatment using paclitaxel chemotherapy. The immune checkpoint inhibitor, nivolumab, improved survival in refractory gastric cancer. Recent studies in gastric cancer clarify the optimal preoperative chemotherapy regimen and the use of PET scan as a response measure of preoperative therapy in esophagogastric cancer, and the role of targeted agents and immune checkpoint inhibitors in metastatic disease.

The ifosfamide, mesna and epirubicin (IMEpi) combination is administered to 16 patients having advanced metastatic breast carcinoma as second-line chemotherapy. We observed complete response in 6%, partial response in 44% (total overall response rate of 50%), stable disease in 12% and progressive disease in the remaining 38% of the patients. The median remission duration in responders was calculated to be 9.6 months. IMEpi regimen had a tolerable toxicity profile including alopecia, nausea and vomiting, microscopic hematuria, leukopenia and neurotoxicity in which serious complications necessitating discontinuation of the chemotherapy were not encountered. It might be concluded that IMEpi chemotherapy combination is an effective alternative among schedules in the management of patients with stage IV breast carcinoma without serious side effects.

(1) To provide recommendations regarding the choice of surgery, radiation therapy (RT), or the combination of surgery plus RT in patients with localized Ewing's sarcoma of bone following neoadjuvant chemotherapy. (2) To determine the appropriate surgical planning imaging (pre-chemotherapy magnetic resonance imaging [MRI] or post-chemotherapy MRI) to identify optimal resection margins in patients with localized Ewing's sarcoma who undergo surgery following neoadjuvant chemotherapy. MEDLINE, EMBASE, the Cochrane Library (1999 to February 2015), main guideline websites, and relevant annual meeting abstracts (2012 to January 2015) were searched. Internal and external reviews were conducted. 1. Recommendation (1) - In patients with localized Ewing's sarcoma of bone following neoadjuvant chemotherapy: (a) Surgery alone or RT alone are two reasonable treatment options; the combination of surgery plus RT is not recommended as an initial treatment option. (b) The local treatment for an individual patient should be decided by a multidisciplinary tumour board together with the patient after consideration of the following: (1) patient characteristics (e.g., age, tumour location, tumour size, response to neoadjuvant chemotherapy, and existing comorbidities), (2) the potential benefit weighed against the potential complications from surgery and/or toxicities associated with RT, and (3) patient preferences. 2. Recommendation (2) - In patients with localized Ewing's sarcoma who will undergo surgery: (a) Both pre-chemotherapy and post-chemotherapy MRI scans should be taken into consideration for surgical planning. In certain anatomic locations with good chemotherapy response, the post-chemotherapy MRI may be the appropriate imaging modality to plan surgical resection margins. Copyright © 2016 Elsevier Ltd.

The primary objective of this study was to evaluate the safety and tolerability of carboplatin plus pemetrexed for elderly patients (≥75 years) with chemotherapy-naïve advanced non-squamous non-small cell lung cancer. Patients received escalated doses of carboplatin at an area under the concentration-time curve of 4 (Level 1) or 5 (Level 2) plus pemetrexed (500 mg/m(2)) every 3 weeks for a maximum of six cycles. Dose escalation was decided according to whether dose-limiting toxicity occurred in the first cycle of chemotherapy. A total of 20 patients (6 at Level 1, 14 at Level 2) were enrolled. No dose-limiting toxicities were observed in patients at Level 1 or the first six patients at Level 2, and therefore the combination of carboplatin at an area under the concentration-time curve of 5 plus pemetrexed at 500 mg/m(2) was considered to be the recommended dose. Among a total of 14 patients in Level 2, only 1 patient experienced dose-limiting toxicity: Grade 3 febrile neutropenia and urticaria. The major toxicities were neutropenia, thrombocytopenia and anemia. Liver dysfunction, fatigue and anorexia were also common, but generally manageable. Six patients showed partial responses, giving the overall response rate of 30%. The median progression-free survival period was 4.8 months (95% confidence interval 2.9-6.7 months). The combination of carboplatin at an area under the concentration-time curve of 5 plus pemetrexed at 500 mg/m(2) was determined as the recommended dose in chemotherapy-naïve elderly patients (≥75 years) with advanced non-squamous non-small cell lung cancer, in view of overall safety and tolerability.

The aim of this phase II study was to evaluate the efficacy of combination chemotherapy consisting of docetaxel and carboplatin in patients with inoperable non-small cell lung cancer (NSCLC). For this multicenter phase II study, the eligibility criteria included histologically or cytologically proven inoperable NSCLC, measurable lesions, Eastern Cooperative Oncology Group performance status (PS) 0-2, adequate organ and bone marrow functions, and written informed consent. Patients received 60 mg/m2 of docetaxel and carboplatin (target AUC 5.5) on day 1 every 3 weeks until disease progression. The primary end-point of this study was response rate and the secondary end-points were toxicities, time to progression and overall survival. A total of 40 patients were enrolled and 39 patients were eligible. A complete response and partial response were observed in 1 and 13 patients, respectively. An objective response rate was 35.9% (95% confidential interval [CI] 20.8-51.0%). The median time to progression was 5.2 months and the median overall survival was 12.0 months. The 1- and 2-year survival rates were 53.8% and 25.1%, respectively. The major toxicities were leukocytopenia and neutropenia. Grade 3 or 4 thrombocytopenia was rare and non-hematological toxicities were generally mild. Grade 3 non-hematological toxicities were observed in 6 patients (2 with nausea and vomiting, 1 with diarrhea, 1 with elevated transaminase levels, 1 with allergic reaction and 1 with edema). No grade 4 non-hematological toxicities were observed. Docetaxel and carboplatin combination chemotherapy was well tolerated and active in Japanese patients with advanced or metastatic NSCLC.

This study aimed to determine the antiemetic efficacy and safety of palonosetron, aprepitant and dexamethasone in patients with testicular germ cell tumours (TGCTs) receiving 5-day cisplatin-based combination chemotherapy. In this open-label, single-arm, single-centre study, the antiemetic therapy consisted of palonosetron 0.75 mg on day 1, aprepitant 125 mg on day 1 and 80 mg on days 2-7 and dexamethasone 6.6 mg on days 1-7. The primary endpoint was complete response (CR; no vomiting/retching or rescue medication) in the overall period (0-240 h), and secondary endpoints included complete protection (CP; defined as CR and no more than mild nausea) and total control (TC; defined as CR and no nausea). The incidence and severity of nausea were assessed on the basis of the Common Terminology Criteria for Adverse Events v4.0 and a subjective rating scale completed by patients. Twenty-five patients were enrolled and evaluated for safety, and 24 patients were evaluated for efficacy. CR was achieved in 62.5% of patients (95% confidence interval [CI] = 40.6-81.2, p = 0.043) in the overall period. CP and TC were achieved in 62.5% (95% CI = 40.6-81.2) and 25.0% of patients (95% CI = 9.8-46.7), respectively, in the overall period. The primary adverse drug reaction was hiccups (48.0%). The events were expected, and none was grade 3 or 4. The examined combination antiemetic therapy was effective and well-tolerated in patients with TGCTs receiving 5-day cisplatin-based combination chemotherapy.

The first aim of this study was to evaluate combination antiemetic therapy consisting of 5-HT3 receptor antagonists, neurokinin-1 receptor antagonists (NK-1RAs), and dexamethasone for multiple high emetogenic risk (HER) anticancer agents in bone and soft tissue sarcoma. The second aim was to compare the effectiveness of single-shot palonosetron and consecutive-day granisetron in a randomized, single-blinded crossover study. A single randomization method was used to assign eligible patients to the palonosetron or granisetron arm. Patients in the palonosetron arm received a palonosetron regimen during the first and third chemotherapy courses and a granisetron regimen during the second and fourth courses. All patients received NK-1RA and dexamethasone. Patients receiving the palonosetron regimen were administered 0.75 mg palonosetron on day 1, and patients receiving the granisetron regimen were administered 3 mg granisetron twice daily on days 1 through 5. All 24 patients in this study received at least 4 chemotherapy courses. A total of 96 courses of antiemetic therapy were evaluated. Overall, the complete response CR rate (no emetic episodes and no rescue medication use) was 34%, while the total control rate (a CR plus no nausea) was 7%. No significant differences were observed between single-shot palonosetron and consecutive-day granisetron. Antiemetic therapy with a 3-drug combination was not sufficient to control chemotherapy-induced nausea and vomiting (CINV) during chemotherapy with multiple HER agents for bone and soft tissue sarcoma. This study also demonstrated that consecutive-day granisetron was not inferior to single-shot palonosetron for treating CINV. © 2014 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

Resected HER2 breast cancer patients treated with adjuvant trastuzumab and chemotherapy have superior survival compared to patients treated with chemotherapy alone. We previously showed that trastuzumab and chemotherapy induce HER2-specific antibodies which correlate with improved survival in HER2 metastatic breast cancer patients. It remains unclear whether the generation of immunity required trastuzumab and whether endogenous antibody immunity is associated with improved disease-free survival in the adjuvant setting. In this study, we addressed this question by analyzing serum anti-HER2 antibodies from a subset of patients enrolled in the NCCTG trial N9831, which includes an arm (Arm A) in which trastuzumab was not used. Arms B and C received trastuzumab sequentially or concurrently to chemotherapy, respectively. Pre-and post-treatment initiation sera were obtained from 50 women enrolled in N9831. Lambda IgG antibodies (to avoid detection of trastuzumab) to HER2 were measured and compared between arms and with disease-free survival. Prior to therapy, across all three arms, N9831 patients had similar mean anti-HER2 IgG levels. Following treatment, the mean levels of antibodies increased in the trastuzumab arms but not the chemotherapy-only arm. The proportion of patients who demonstrated antibodies increased by 4% in Arm A and by 43% in the Arms B and C combined (p = 0.003). Cox modeling demonstrated that larger increases in antibodies were associated with improved disease-free survival in all patients (HR = 0.23; p = 0.04). These results show that the increased endogenous antibody immunity observed in adjuvant patients treated with combination trastuzumab and chemotherapy is clinically significant, in view of its correlation with improved disease-free survival. The findings may have important implications for predicting treatment outcomes in patients treated with trastuzumab in the adjuvant setting. ClinicalTrials.gov, NCT00005970 .

Local hyperthermia combined with intralesional cisplatin chemotherapy is a logical and potentially effective therapeutic approach for localized cancers. A trial using outbred animals with spontaneously occurring tumours was initiated to evaluate the toxicity and efficacy of this approach. Treatment consisted of injection of a colloidal suspension of cisplatin into the tumour prior to hyperthermia once a week for 4 weeks. Immediately after intratumoral injection of a mixture of cisplatin and collagen, thermotherapy was given. The goal temperature was 42 +/- 1 degrees C for 30 min. Ten animals (nine dogs and one cat) with soft tissue neoplasms were treated with one to four hyperthermia and cisplatin sessions for a total of 30 treatment sessions. Complete responses occurred in 4/10 cases (one carcinoma, two sarcomas, one melanoma). One dog with haemangiopericytoma had partial response. The lack of systemic toxicity and the minimal local normal tissue reactions indicate that the treatments were well tolerated. These data provide preliminary evidence that a combination of local hyperthermia and intratumoral cisplatin chemotherapy is a safe and effective method for the treatment of selected localized neoplasms.

Background. KRAS mutation is an important predictive and prognostic factor for patients receiving anti-EGFR therapy. An expanded KRAS, NRAS, BRAF, PIK3CA mutation analysis provides additional prognostic information, but its role in predicting bevacizumab efficacy is unclear. The aim of our study was to evaluate the incidence of KRAS, NRAS, BRAF and PIK3CA mutations in metastatic colorectal cancer patients receiving first line oxaliplatin based chemotherapy with or without bevacizumab and to evaluate their prognostic and predictive significance. Methods. 55 patients with the first-time diagnosed CRC receiving FOLFOX ± bevacizumab were involved in the study. Tumour blocks were tested for KRAS mutations in exons 2, 3 and 4, NRAS mutations in exons 2, 3 and 4, BRAF mutation in exon 15 and PIK3CA mutations in exons 9 and 20. The association between mutations and clinico-pathological factors, treatment outcomes and survival was analyzed. Results. KRAS mutations were detected in 67.3% of the patients, BRAF in 1.8%, PIK3CA in 5.5% and there were no NRAS mutations. A significant association between the high CA 19–9 level and KRAS mutation was detected (mean CA 19–9 levels were 276 and 87 kIU/l, respectively, p = 0.019). There was a significantly higher response rate in the KRAS, NRAS, BRAF and PIK3CA wild type cohort receiving bevacizumab compared to any gene mutant type (100 and 60%, respectively, p = 0.030). The univariate Cox regression analysis did not confirm KRAS and other tested mutations as prognostic factors for PFS or OS. Conclusions. Our study revealed higher KRAS and lower NRAS, BRAF and PIK3CA mutation rates in the Lithuanian population than those reported in the literature. KRAS mutation was associated with the high CA 19–9 level and mucinous histology type, but did not show any predictive or prognostic significance. The expanded KRAS, NRAS, BRAF and PIK3CA mutation analysis provided additional significant predictive information. PMID:28356789

Background We aimed to investigate the patterns of failure (locoregional and distant metastasis), associated factors, and treatment outcomes in nasopharyngeal carcinoma patients treated with intensity-modulated radiation therapy (IMRT) combined with chemotherapy. Patients and methods From April 2006 to December 2011, 68 nasopharyngeal carcinoma patients were treated with IMRT and chemotherapy at our hospital. Median radiation doses delivered to gross tumor volume and positive neck nodes were 66–70 Gy, 63 Gy to clinical target volume, and 50.4–56 Gy to clinically negative neck. The clinical toxicities, patterns of failures, locoregional control, distant metastasis control, disease-free survival, and overall survival were observed. Results The median follow-up time was 52.2 months (range: 11–87 months). Epstein–Barr virus infection was positive in 63.2% of patients. Overall disease failure developed in 21 patients, of whom 85.8% belonged to stage III/IV disease. Among these, there were seven locoregional recurrences, three regional recurrences with distant metastases, and eleven distant metastases. The median interval from the date of diagnosis to failure was 26.5 months (range: 16–50 months). Six of ten (60%) locoregional recurrences were treated with reirradiation ± concurrent chemotherapy. The 5-year locoregional control, distant metastasis control, disease-free survival, and overall survival rates of whole cohort were 81.1%, 74.3%, 60.1%, and 73.4%, respectively. Cox regression analyses revealed that neoadjuvant chemotherapy, age, and Epstein–Barr virus were independent predictors for disease-free survival. Conclusion Neoadjuvant chemotherapy followed by IMRT with or without chemotherapy improves the long-term survival of Saudi patients with nasopharyngeal carcinoma. Distant metastasis was the main pattern of treatment failure. Neoadjuvant chemotherapy, age, and Epstein–Barr virus status before IMRT were important independent prognostic factors. PMID:27822060

Purpose In the phase III KEYNOTE-045 study ( ClinicalTrials.gov identifier: NCT02256436), pembrolizumab significantly prolonged overall survival compared with investigator's choice of chemotherapy in patients with previously treated advanced urothelial cancer. Here, we report the results of health-related quality-of-life (HRQoL) analyses from the KEYNOTE-045 trial. Patients and Methods Patients were randomly assigned 1:1 to pembrolizumab 200 mg or investigator's choice of docetaxel 75 mg/m 2 , paclitaxel 175 mg/m 2 , or vinflunine 320 mg/m 2 administered intravenously every 3 weeks. Key prespecified HRQoL analyses were time to deterioration (TTD) and mean change from baseline to week 15 in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 global health status/quality-of-life score. Results Of 542 patients who were randomly assigned, 519 were included in HRQoL analyses (pembrolizumab, n = 266; chemotherapy, n = 253). HRQoL compliance was > 95% at baseline and approximately 88% at week 15 for both groups. Pembrolizumab prolonged TTD in global health status/quality-of-life score compared with chemotherapy (median, 3.5 months v 2.3 months; hazard ratio, 0.72; nominal one-sided P = .004). Mean (95% CI) change from baseline to week 15 in global health status/quality-of-life score was 0.69 (-2.40 to 3.77) with pembrolizumab and -8.36 (-11.84 to -4.89) with chemotherapy (mean difference, 9.05 points; 95% CI, 4.61 to 13.50; nominal two-sided P < .001). Conclusion Pembrolizumab prolonged TTD in HRQoL compared with chemotherapy. Patients who were treated with pembrolizumab had stable or improved global health status/quality of life, whereas those who were treated with investigator's choice of chemotherapy experienced declines in global health status/quality of life. Combined with efficacy and safety outcomes, these data support pembrolizumab as standard of care for patients with platinum-refractory advanced urothelial cancer.

The optimal use of epidermal growth factor receptor (EGFR)-related molecular markers to prospectively identify tyrosine kinase inhibitor (TKI)-sensitive patients, particularly after a previous chemotherapy treatment, is currently under debate. We designed a prospective phase II study to evaluate the activity of EGFR-TKI in four different patient groups, according to the combination of molecular (EGFR gene mutations, EGFR gene copy number and protein expression, and phosphorylated AKT expression, pAKT) and clinicopathological (histology and smoking habits) factors. Correlations between molecular alterations and clinical outcome were also explored retrospectively for first-line chemotherapy and EGFR-TKI treatment. Patients who had progressed during or after first-line chemotherapy were prospectively assigned to EGFR-TKI treatment as follows: (G1) EGFR mutation (n = 12); (G2) highly polysomic/amplified EGFR (n = 18); (G3) EGFR and/or pAKT positive (n = 41); (G4) adenocarcinoma/bronchoalveolar carcinoma and no smoking history (n = 15). G1 and G4 had the best and second-best overall response rate (25% and 20%, respectively), whereas the worst outcome was observed in G2 (ORR, 6%; p = 0.05). Disease control was highest in G1 and G4 (>50%) and lowest in G3 (<20%) (p = 0.02). Patients selected by EGFR mutation or clinical parameters (G1 and G4) also had significantly better progression-free survival and overall survival (p = 0.02 and p = 0.01, respectively). Multivariate analysis confirmed the impact of sex, smoking history, EGFR/KRAS mutation, and pAKT on outcomes and allowed us to derive an efficient predictive model. Histology, EGFR mutations, and pAKT were independent predictors of response to first-line chemotherapy at retrospective analysis, whereas pAKT and human epidermal growth factor receptor 2 expression were the only independent predictors of progression-free survival and overall survival. Selection of patients based on either EGFR mutation or clinical characteristics seems an effective approach to optimize EGFR-TKI treatment in chemotherapy-pretreated non-small-cell lung cancer patients.

Premenopausal patients with breast cancer are at high risk of premature ovarian failure induced by systemic treatments, but no standard strategies for preventing this adverse effect are yet available. To determine the effect of the temporary ovarian suppression obtained by administering the gonadotropin-releasing hormone analogue triptorelin during chemotherapy on the incidence of early menopause in young patients with breast cancer undergoing adjuvant or neoadjuvant chemotherapy. The PROMISE-GIM6 (Prevention of Menopause Induced by Chemotherapy: A Study in Early Breast Cancer Patients-Gruppo Italiano Mammella 6) study, a parallel, randomized, open-label, phase 3 superiority trial, was conducted at 16 sites in Italy and enrolled 281 patients between October 2003 and January 2008. The patients were premenopausal women with stage I through III breast cancer who were candidates for adjuvant or neoadjuvant chemotherapy. Assuming a 60% rate of early menopause in the group treated with chemotherapy alone, it was estimated that 280 patients had to be enrolled to detect a 20% absolute reduction in early menopause in the group treated with chemotherapy plus triptorelin. The intention-to-treat analysis was performed by including all randomized patients and using imputed values for missing data. Before beginning chemotherapy, patients were randomly allocated to receive chemotherapy alone or combined with triptorelin. Triptorelin was administered intramuscularly at a dose of 3.75 mg at least 1 week before the start of chemotherapy and then every 4 weeks for the duration of chemotherapy. Incidence of early menopause (defined as no resumption of menstrual activity and postmenopausal levels of follicle-stimulating hormone and estradiol 1 year after the last cycle of chemotherapy). The clinical and tumor characteristics of the 133 patients randomized to chemotherapy alone and the 148 patients randomized to chemotherapy plus triptorelin were similar. Twelve months after the last cycle of chemotherapy (last follow-up, August 18, 2009), the rate of early menopause was 25.9% in the chemotherapy-alone group and 8.9% in the chemotherapy plus triptorelin group, an absolute difference of -17% (95% confidence interval, -26% to -7.9%; P < .001). The odds ratio for treatment-related early menopause was 0.28 (95% confidence interval, 0.14 to 0.59; P < .001). The use of triptorelin-induced temporary ovarian suppression during chemotherapy in premenopausal patients with early-stage breast cancer reduced the occurrence of chemotherapy-induced early menopause. clinicaltrials.gov Identifier: NCT00311636.

A combined model of human erythropoiesis and granulopoiesis under growth factor and chemotherapy treatment

PubMed Central

2014-01-01

Background Haematotoxicity of conventional chemotherapies often results in delays of treatment or reduction of chemotherapy dose. To ameliorate these side-effects, patients are routinely treated with blood transfusions or haematopoietic growth factors such as erythropoietin (EPO) or granulocyte colony-stimulating factor (G-CSF). For the latter ones, pharmaceutical derivatives are available, which differ in absorption kinetics, pharmacokinetic and -dynamic properties. Due to the complex interaction of cytotoxic effects of chemotherapy and the stimulating effects of different growth factor derivatives, optimal treatment is a non-trivial task. In the past, we developed mathematical models of thrombopoiesis, granulopoiesis and erythropoiesis under chemotherapy and growth-factor applications which can be used to perform clinically relevant predictions regarding the feasibility of chemotherapy schedules and cytopenia prophylaxis with haematopoietic growth factors. However, interactions of lineages and growth-factors were ignored so far. Results To close this gap, we constructed a hybrid model of human granulopoiesis and erythropoiesis under conventional chemotherapy, G-CSF and EPO applications. This was achieved by combining our single lineage models of human erythropoiesis and granulopoiesis with a common stem cell model. G-CSF effects on erythropoiesis were also implemented. Pharmacodynamic models are based on ordinary differential equations describing proliferation and maturation of haematopoietic cells. The system is regulated by feedback loops partly mediated by endogenous and exogenous EPO and G-CSF. Chemotherapy is modelled by depletion of cells. Unknown model parameters were determined by fitting the model predictions to time series data of blood counts and cytokine profiles. Data were extracted from literature or received from cooperating clinical study groups. Our model explains dynamics of mature blood cells and cytokines after growth-factor applications in healthy volunteers. Moreover, we modelled 15 different chemotherapeutic drugs by estimating their bone marrow toxicity. Taking into account different growth-factor schedules, this adds up to 33 different chemotherapy regimens explained by the model. Conclusions We conclude that we established a comprehensive biomathematical model to explain the dynamics of granulopoiesis and erythropoiesis under combined chemotherapy, G-CSF, and EPO applications. We demonstrate how it can be used to make predictions regarding haematotoxicity of yet untested chemotherapy and growth-factor schedules. PMID:24886056

The current study aims to evaluate and compare the efficacy of post-operative chemotherapy using paclitaxel plus carboplatin or nedaplatin in patients with ovarian cancer, as well as the effects of different combinational therapies on the survival times of patients. Ninety-four patients were recruited for the study. These ovarian cancer patients were admitted into the Cancer Hospital Affiliated with Harbin Medical University for surgery from January 2008 to October 2009. They were divided into different groups according to their post-operative chemotherapy schemes: paclitaxel plus carboplatin (CBP group, n = 48) and paclitaxel plus nedaplatin (NDP group, n = 46). Variance analysis was used to compare the effects of different chemotherapy schemes and pathological types of ovarian cancer on the level of CA125 in serum at different treatment time points. Univariate and multivariate analyses were employed to evaluate the survival times of patients in different groups and pathological types and ages. No significant differences were observed regarding the effects of various chemotherapy schemes (P = 0.561) and pathological types (P = 0.903) on the level of CA125 in serum of patients with ovarian cancer. However, the duration of chemotherapy had a profound impact on the level of CA125 in serum (P < 0.001). The survival times of patients was not affected by age (P = 0.101) and pathological type of ovarian cancer (P = 0.94) significantly. However, it was significantly affected by the chemotherapy scheme. Combined chemotherapy using carboplatin plus paclitaxel should be considered as the preferred treatment scheme for the initial treatment of ovarian cancer.

The inactivation of the p53 tumor suppressor pathway, which often occurs through mutations in TP53 (encoding tumor protein 53) is a common step in human cancer. However, in melanoma—a highly chemotherapy-resistant disease—TP53 mutations are rare, raising the possibility that this cancer uses alternative ways to overcome p53-mediated tumor suppression. Here we show that Mdm4 p53 binding protein homolog (MDM4), a negative regulator of p53, is upregulated in a substantial proportion (∼65%) of stage I–IV human melanomas and that melanocyte-specific Mdm4 overexpression enhanced tumorigenesis in a mouse model of melanoma induced by the oncogene Nras. MDM4 promotes the survival of human metastatic melanoma by antagonizing p53 proapoptotic function. Notably, inhibition of the MDM4-p53 interaction restored p53 function in melanoma cells, resulting in increased sensitivity to cytotoxic chemotherapy and to inhibitors of the BRAF (V600E) oncogene. Our results identify MDM4 as a key determinant of impaired p53 function in human melanoma and designate MDM4 as a promising target for antimelanoma combination therapy. PMID:22820643

Purpose To update key recommendations of the ASCO guideline adaptation of the Cancer Care Ontario guideline on the selection of optimal adjuvant chemotherapy regimens for early breast cancer and adjuvant targeted therapy for breast cancer. Methods An Expert Panel conducted targeted systematic literature reviews guided by a signals approach to identify new, potentially practice-changing data that might translate to revised practice recommendations. Results The Expert Panel reviewed phase III trials that evaluated adjuvant capecitabine after completion of standard preoperative anthracycline- and taxane-based combination chemotherapy by patients with early-stage breast cancer HER2-negative breast cancer with residual invasive disease at surgery; the addition of 1 year of adjuvant pertuzumab to combination chemotherapy and trastuzumab for patients with early-stage, HER2-positive breast cancer; and the use of neratinib as extended adjuvant therapy for patients after combination chemotherapy and trastuzumab-based adjuvant therapy with early-stage, HER2-positive breast cancer. Recommendations Patients with early-stage HER2-negative breast cancer with pathologic, invasive residual disease at surgery following standard anthracycline- and taxane-based preoperative therapy may be offered up to six to eight cycles of adjuvant capecitabine. Clinicians may add 1 year of adjuvant pertuzumab to trastuzumab-based combination chemotherapy in patients with high-risk, early-stage, HER2-positive breast cancer. Clinicians may use extended adjuvant therapy with neratinib to follow trastuzumab in patients with early-stage, HER2-positive breast cancer. Neratinib causes substantial diarrhea, and diarrhea prophylaxis must be used. Additional information can be found at www.asco.org/breast-cancer-guidelines .

Few data exist on how elderly patients with colorectal cancer (CRC) are actually treated in real-life practice. Based on a national cohort, we analysed routine treatment modalities of the elderly who were diagnosed with CRC in France in 2009. The characteristics of patients and tumours and the cancer treatments received during the first year of all national incident cases of CRC diagnosed between 1st April and 31st December 2009, were compared between a 'younger group' (YG), under 75 years of age (N = 18,410 patients), and an 'older group' (OG), aged 75 and over (N = 13,255 patients). In the OG with metastases at baseline, we analysed two-year overall survival (OS) according to the treatment received (e.g. chemotherapy, surgery) and well-known prognostic factors. Among patients with localised CRC (N = 25,353), surgery was equally performed in both groups in more than 80% of the cases (p=0.52); time to surgery was shorter in the OG (8 versus 23 days) because there was more emergency surgery for occlusion among the OG. Adjuvant chemotherapy was performed in 15% of the OG (versus 29% in the YG) and consisted of 5-fluorouracil (5FU) monotherapy in more than 50% of OG patients. Among patients with metastatic CRC (N = 6,312), palliative chemotherapy was given to 48% of the OG versus 85% of the YG. Chemotherapy regimens included 30% monotherapy with 5FU, 30% oxaliplatin combination and 20% bevacizumab combination in the OG; compared to 10%, 34% and 35%, respectively, in the YG. The median OS for the OG was 8.4 months (versus 22.3 months in the YG) and 17.1 months among elderly patients who received chemotherapy. CRC is more frequently complicated at diagnosis among elderly patients. Adjuvant and palliative chemotherapy is less frequently prescribed among elderly patients. This could be explained by the fact that unfit elderly patients do not deserve chemotherapy, but certainly also reflect the fact that some fit elderly patients are undertreated.

Carboplatin-paclitaxel chemotherapy combination is the standard first-line treatment of advanced ovarian cancer and is the most commonly used treatment combination shown to be effective in advanced non-small-cell lung cancer (NSCLC). The most important dose-limiting side effect is hematologic toxicity. In this study, the severity of treatment-related myelotoxicity is compared in patients with advanced ovarian and lung cancers who received same schedule of carboplatin-paclitaxel. The study was prospectively performed from February 2009 to July 2011 and involved 103 patients with stages Ic-IV ovarian (n = 51) and advanced NSCLC (n = 52) who were administered a maximum of 6 cycles of carboplatin-paclitaxel as a first-line treatment. Full blood counts were measured before treatment, before each chemotherapy cycle during therapy, and at the first and sixth month after therapy. The median ages were 59 years (range, 35-77 years) for patients with NSCLC and 56 years (range, 38-75 years) for patients with ovarian cancer. The frequencies of anemia were 17% and 28.6% before the initiation of chemotherapy, 39.2% and 68.0% at the third cycle of treatment, and 44.2% and 45.2% at the sixth cycle of treatment in patients with NSCLC and ovarian cancer, respectively. Initial leukopenia rates were 3.4% and 0%; at the third cycle 46.0% and 41.2%; and at the sixth cycle 41.9% and 48.8% in patients with NSCLC and ovarian cancer, respectively. At the third cycle, 2.5% of the patients with NSCLC and 10.4% of the patients with ovarian cancer had thrombocytopenia, and at the sixth cycle, 23.3% of the patients with NSCLC and 25% of the patients with ovarian cancer had thrombocytopenia. Hemoglobin, leukocyte, and platelet values at the third cycle were significantly lower than those at admission in both cancer groups. Declines in hemoglobin levels in patients with NSCLC and in platelets in patients with ovarian cancer at the sixth cycle were statistically significant compared with the third cycle. In conclusion, the same schedule of chemotherapy may lead to different myelotoxicities in different types of cancer. These results should be taken into consideration in terms of supportive care and management of toxicity.

This study is a retrospective analysis evaluating the efficacy and toxicity of combination chemotherapy with S-1 and oxaliplatin (SOX) as first-line treatment in elderly patients with advanced gastric cancer. One hundred and twenty-nine patients with recurrent or metastatic gastric adenocarcinoma were treated with SOX; S-1 (40-60 mg depending on patient's body surface area) was given orally, twice daily on days 1 to 14 followed by a 7-day rest period, 130 mg/m(2) oxaliplatin was given as an intravenous infusion over 2-hours on day one. The cycle was repeated every three weeks. All of the patients were older than 65 years. Among 129 patients enrolled, nine patients could not be evaluated for responses because of the absence of any measurable lesions or early discontinuation of therapy. Assessment of the response of 120 patients was made. The overall objective response rate was 54.2 % (95 %CI, 45.3-63.1 %), with three complete responses and 62 partial responses. The disease control rate was 80.8 % (95 %CI, 73.8-87.8 %). The median follow-up period was 23 months (range, 5-42 months). The median time to progression was 6.9 months (95 %CI, 5.5-8.3 months) and the median overall survival was 12.8 months (95 %CI, 11.4-14.2 months). The one-year survival rate was 57.5 % (95 %CI, 48.7-66.3 %). In 129 patients assessed safety, grade 3 and 4 toxicities included leucopenia (20.9 %), neutropenia (24.0 %), anemia (10.9 %), thrombocytopenia (10.1 %), anorexia (3.1 %), peripheral neurotoxicity (15.5 %), and fatigue (12.4 %). No treatment-related deaths occurred. Combination chemotherapy with SOX offers an effective, safe and well-tolerated regimen for elderly patients with advanced gastric cancer.

Background As rituximab combined with CHOP improves complete remission and overall survival in diffuse large B-cell lymphoma, intensified chemotherapy followed by autologous stem-cell transplantation has also been advocated for high-risk patients. The aim of this study was to establish whether or not combining rituximab with high-dose chemotherapy and auto-transplantation also benefits patient survival. Design and Methods The LNH2003-3 study was a phase II trial including diffuse large B-cell lymphoma patients with 2 or 3 International Prognostic Index factors. They received four cycles of intensive biweekly chemotherapy with rituximab, doxorubicine, cyclophosphamide, vindesine, bleomycine, prednisolone (R-ACVBP) followed by auto-transplantation in responding patients. Two hundred and nine patients under 60 years of age were included in the study and 155 responding patients underwent auto-transplantation. In addition, a case-control study was performed by matching (1:1) 181 patients treated with R-ACVBP with ACVBP patients not given rituximab but submitted to auto-transplantation from the previous LNH1998-3 trial. Results With a median follow up of 45 months, 4-year progression-free survival and overall survival were estimated at 76% (CI: 69–81) and 78% (CI: 72–83), respectively. There was no difference between patients with 2 or 3 International Prognostic Index factors. Four year progression-free survival was significantly higher in R-ACVBP than ACVBP patients (74% vs. 58%; P=0.0005). There was also a significant increase in 4-year overall survival (76% vs. 68%; P=0.0494). Conclusions In high-risk diffuse large B-cell lymphoma patients, treatment with R-ACVBP followed by auto-transplantation results in a 78% 4-year overall survival which should be compared to other approaches.

To analyze the duration of preventive filgrastim administration as support for chemotherapy and its affecting factors. Single institutional data from a phase Ⅱ clinical trial and a phase Ⅲ clinical trial of pegylated filgrastim were combined. In the two randomized cross-over trials, patients with previously untreated cancer received two cycles of chemotherapy of the same regimen. In the study group, the patients received a single subcutaneous injection of 100 μg/kg pegylated filgrastim, and in the control group, they received daily subcutaneous injections of 5 μg/kg filgrastim. In 53 chemotherapy cycles, the median duration of filgrastim administration was (9.57±2.10)d. 83.0% (44/53) of them received filgrastim for 7-11 days. Patients with baseline absolute neutrophil count of <4×10(9)/L or body mass index less than 22 received a longer filgrastim prophylaxis(P<0.05). RESULTS of multivariate analysis showed that the baseline absolute neutrophil count is associated with the time of filgrastim administration(P=0.019). The most common adverse event of rhG-CSF was skeletal pain, generally mild and no treatment-related death occurred. The median duration of filgrastim support for chemotherapy was 10 days. Patients with lower baseline neutrophil count require a longer filgrastim prophylaxis. : ClinicalTrials.gov identifier, NCT01285219.

We present a pooled analysis of predictive and prognostic values of circulating tumour cells (CTC) and circulating endothelial cells (CEC) in two prospective trials of patients with inflammatory breast cancer (IBC) treated with neoadjuvant chemotherapy combined with neoadjuvant and adjuvant bevacizumab. Nonmetastatic T4d patients were enrolled in two phase II multicentre trials, evaluating bevacizumab in combination with sequential neoadjuvant chemotherapy of four cycles of FEC followed by four cycles of docetaxel in HER2-negative tumour (BEVERLY-1) or docetaxel and trastuzumab in HER2-positive tumour (BEVERLY-2). CTC and CEC were detected in 7.5 and 4 ml of blood, respectively, with the CellSearch System. From October 2008 to September 2010, 152 patients were included and 137 were evaluable for CTC and CEC. At baseline, 55 patients had detectable CTC (39%). After four cycles of chemotherapy, a dramatic drop in CTC to a rate of 9% was observed (P < 0.01). Pathological complete response (pCR) rate was 40%. No correlation was found between CTC or CEC levels and pCR rate. Median follow-up was 43 months. CTC detection (≥1 CTC/7.5 ml) at baseline was associated with shorter 3-year disease-free survival (39% versus 70% for patients without CTC, P < 0.01, HR 2.80) and shorter 3-year overall survival (OS) (P < 0.01). In multivariate analysis, independent prognostic parameters for shorter survival were absence of hormonal receptors, no pCR and CTC detection at baseline. CEC level at baseline or variations during treatment had no prognostic value. In this pooled analysis of two prospective trials in nonmetastatic IBC, detection rate of CTC was 39% with a strong and independent prognostic value for survival. Combination of pCR after neoadjuvant treatment with no CTC detection at baseline isolated a subgroup of IBC with excellent OS (94% 3-year OS), suggesting that CTC count could be part of IBC stratification in prospective trials. © The Author 2016.

Objective: To evaluate the efficacy of large spot indirect ophthalmoscopy laser alone or combined with systemic chemotherapy in the treatment of early and middle stage retinoblastoma. Methods: Retrospective series case study. Clinical data of 21 patients (22 eyes) who were diagnosed as retinoblastoma (RB) in Peking University People's Hospital from March 2009 to August 2014 were collected. Medical and family history, ocular ultrasound, orbital and cranial MRI or CT examination of RB Children were detailed recorded. Ocular examination and laser treatment were performed under general anesthesia, once every 3-4 weeks until the tumor was under control. The observation period was at least 3 months after the last treatment. The ocular examination included intraocular pressure measurement, anterior segment and fundus examination and the fundus photography with Retcam. Laser therapeutic instrument was large spot indirect ophthalmoscopy laser of 810nm wavelength. Results: Of the 21 children, 16 were male and 5 were female. The range of age was 3 to 82 months averaged 17.3 months. Among 22 eyes, four with small tumor, eight with medium tumor, and ten with large tumor. Two eyes underwent laser treatment only and 20 eyes underwent laser treatment combined with systemic chemotherapy. During the average observation period of 33.9 months, 15 tumors were treated successfully, but 7 failed. The total success rate was 68.2%. The number and success rate of small, medium and large tumor eyes were 4 (100%), 5 (62.5%) and 5 (50%), respectively. There was one case of tumor brain metastases, and the classification of contralateral eye of the child was E phase. Iris burns happened in one eye, obvious vitreous proliferation in one eye and mild vitreous hemorrhage occurred in two eyes, which did not affect the treatment of laser. However, obvious tumor hemorrhage happened in two eyes and affected laser therapy. There was no complicated cataract, iatrogenic retinal hole and tumor intravitreal implant caused by laser blasting effect. Conclusions: Indirect ophthalmoscope laser in 810-nm diode laser with large-spot alone or combined with systemic chemotherapy may be effective treatment for retinoblastoma in earlier than stage C of international classification. It is suitable for large and multiple retinoblastoma. (Chin J Ophthalmol, 2016, 52: 745-748) .

Management of advanced non-small-cell lung cancer in elderly populations.

PubMed

Lilenbaum, Rogerio

2003-11-01

Elderly patients, defined as those >or= 70 years of age, represent approximately 40% of all patients diagnosed with non-small-cell lung cancer in the United States. Nonetheless, elderly patients have been underrepresented in national cooperative group trials, and many do not receive appropriate treatment. Whereas the benefit of systemic chemotherapy in younger patients is accepted by most clinicians, there remains a great deal of skepticism with respect to older patients, who are often labeled unfit for chemotherapy. More recent studies with a special focus on elderly patients demonstrate that these patients indeed benefit from chemotherapy. The landmark Elderly Lung Cancer Vinorelbine Italian Study Group trial and the Multicentre Italian Lung Cancer in the Elderly Study clarified the role of vinorelbine in the treatment of elderly patients. Retrospective and prospective subgroup analyses from selected North American trials suggested that elderly patients also benefit from platinum-based combinations. Whether elderly patients should be treated with single-agent versus combination chemotherapy is discussed in this review. The available data suggest that patients should be evaluated for chemotherapy based on their performance status and comorbidities rather than age alone. For elderly patients judged fit to receive combination chemotherapy, carboplatin-based regimens are a reasonable option. In elderly patients with less than optimal performance status or significant comorbid conditions, single-agent therapy may be more appropriate.

S-1 is a new oral fluoropyrimidine formulation that comprises tegafur, 5-chloro-2,4-dihydroxypyridine, and potassium oxonate. S-1 is designed to enhance antitumor activity and to reduce gastrointestinal toxicity. Several studies have demonstrated that both S-1 monotherapy and S-1 combination regimens showed encouraging efficacies and mild toxicities in the treatment of lung squamous cell carcinoma and adenocarcinoma. However, it is unclear whether S-1 can be used as standard care in advanced non-small cell lung cancer (NSCLC). The purpose of this meta-analysis was to assess the efficacy and safety of S-1-based chemotherapy, compared with standard chemotherapy, in patients with locally advanced or metastatic NSCLC. Thirteen randomized controlled trials (RCTs) involving 2,134 patients with a similar ratio of different pathological types were included. In first-line or second-line chemotherapy, compared with standard chemotherapy, S-1-based chemotherapy showed similar efficacy in terms of median overall survival (mOS), median progression free survival (mPFS), and objective response rate (ORR) (all P > 0.1), and significantly reduced the incidence of grade ≥ 3 hematological toxicities. In patients with locally advanced NSCLC receiving concurrent chemoradiotherapy, compared with standard chemoradiotherapy, significantly improved survival in the S-1-based chemotherapy was noted in terms of mOS and mPFS (risk radio [RR] = 1.289, P = 0.009; RR = 1.289, P = 0.000, respectively) with lower incidence of grade ≥ 3 neutropenia (RR = 0.453, P = 0.000). The present meta-analysis demonstrates that S-1-based chemotherapy shows similar benefits in advanced NSCLC and improves survival in locally advanced NSCLC, compared with standard treatment.

Although several clinical trials have demonstrated the benefits of platinum-combined adjuvant chemotherapy for resected non-small cell lung cancer (NSCLC), predictive biomarkers for the efficacy of such therapy have not yet been identified. Selection of patients with high metastatic ability in the early stage of non-small cell lung cancer (NSCLC) has the potential to predict clinical benefit of adjuvant chemotherapy (ADJ).In order to develop a predictive biomarker for efficacy of ADJ, we reanalyzed patient data using a public database enrolled by JBR.10, which was a clinical trial to probe the clinical benefits of ADJ in stage-IB/II patients with NSCLC. The patients who were enrolled by JBR.10 were classified into 2 subgroups according to expression of the ACTN4 transcript: ACTN4 positive (ACTN4 (+)) and ACTN4 negative (ACTN4 (-)). In the ACTN4 (+) group, overall survival (OS) was significantly higher in the ADJ subgroup compared with the observation subgroup (OBS), indicating a significant survival benefit of ADJ. However, no difference in OS was found between ADJ and OBS groups in ACTN4 (-). Although ACTN4 expression level did not correlate with the chemosensitivity of cancer cell lines for cytotoxic drugs, the metastatic potential of A549 lung adenocarcinoma cells was significantly reduced by ACTN4 shRNA in in vitro assays and in an animal transplantation model. The clinical and preclinical data suggested that ACTN4 is a potential predictive biomarker for efficacy of ADJ in stage-IB/II patients with NSCLC, by reflecting the metastatic potential of tumor cells.

TAFRO (thrombocytopenia, anasarca, myelofibrosis, renal dysfunction, and organomegaly) syndrome is an atypical manifestation of Castleman's disease. However, the mechanism underlying this very rare syndrome remains unknown, and there is no established standard treatment. Here we report cases of two young females with TAFRO syndrome who showed similar clinical courses. Both cases showed severe anasarca, ascites, and thrombocytopenia. Although high-dose steroids were ineffective, combination chemotherapy showed remarkable effects. However, both patients developed severe but reversible heart failure after CHOP therapy owing to diffuse cardiomyopathy, which was presumably associated with TAFRO syndrome. Therefore, although combination chemotherapy may be very effective in the treatment of TAFRO syndrome, careful observation for cardiomyopathy development is needed, particularly when using adriamycin-containing regimens.

MTT were used to examine the growth inhibition of Hep-2 cells treated by the combination of PB with 5-FU or CDDP in vitro. When 5-FU or CDDP combined with PB respectively, there was significantly difference between every two dose groups of the two agents or every dose group and control group ( P < 0.05). When the dosage of 5-FU or CDDP was definition,there was significantly difference between every two dose groups of PB ( P < 0.05). PB could enhance the cytotoxic effects of agents used in induction chemotherapy on laryngeal carcinoma cells Hep-2 in vitro, which showed the possibility in reinforcement the treatment effect and reduction the occurrence of the complication and toxic reaction of induction chemotherapy on laryngeal carcinoma.

Frontline strategy for follicular lymphoma: are we ready to abandon chemotherapy?

PubMed

Fowler, Nathan

2016-12-02

Chemotherapy combinations have been the backbone of therapy for follicular lymphoma, and are associated with high initial response rates. Unfortunately, toxicity and secondary malignancies remain concerns, and most advanced-stage patients still relapse within 5 years, regardless of the regimen. Advances in the understanding of lymphoma biology have resulted in a new generation of noncytotoxic therapeutics with significant activity in follicular lymphoma. Recent studies exploring biological and targeted combinations in the frontline have shown promise, with response rates similar to chemotherapy. However, these regimens are also associated with significant cost as well as a unique toxicity profile. Large randomized studies are underway to compare noncytotoxic regimens with chemotherapy in the frontline, and several new combinations are being tested in the phase 2 setting. Ongoing work to identify predictive biomarkers and investment in mechanistic studies will ultimately lead to the personalization of therapy in the frontline setting for follicular lymphoma. © 2016 by The American Society of Hematology.

Primary tumors of the trachea are rare. Such cases are presented with acute respiratory distress demanding immediate therapeutic intervention. Herein, we present a case of an unresectable second primary tracheal cancer treated with intraluminal brachytherapy (8 Gy at 1 cm from catheter) followed by a short course of external beam hypofractionated radiotherapy (4.5 Gy × 4 fractions) and a final brachytherapy fraction (8 Gy), delivering a biological dose higher than 57.5 Gy (for α/β = 4 Gy) to the tumor within 4 weeks. Concurrent chemotherapy consisted of: fluoruracil (1000 mg/m2), leucovorin (100 mg/m2), oxaliplatin (80 mg/m2) and cetuximab (500 mg/m2), administered every two weeks for two consecutive cycles. Complete response was evident during the second brachytherapy fraction and the patient is alive with no evidence of disease, two years after therapy, without any late radiation sequel. PMID:27853478

OBJECTIVE: The purpose of this study was to confirm whether Black and White women with endometrial cancer are equally tolerant of chemotherapy and identify factors that impact survival. METHODS: A retrospective review of 169 Black women and 982 White women with FIGO Stage III/IV or recurrent endometrial carcinoma was performed. All patients received doxorubicin combined with cisplatin. Chemotherapy parameters that were reviewed included relative dose (RD), relative time (RT), and relative dose intensity (RDI). Treatment cycles ≥ 7 were defined as treatment completion. RESULTS: Although Black patients were more likely to experience grade 3-4 anemia (20% vs. 14%) and genitourinary (5% vs. 1%) toxicity, and less likely to experience severe GI toxicity (10% vs. 17%), the overall incidence of grade 3-4 treatment-related chemotoxicity was the same between the two groups (82% vs. 82%). There were no differences in the number of cycles received, RD (0.57 vs. 0.58), RT (0.77 vs. 0.78), or RDI (0.76 vs. 0.76) for Black and White patients. CONCLUSION: Black patients with advanced stage or recurrent endometrial cancer, treated on four GOG protocols, had similar dose intensity and severe chemotherapy-related toxicity compared to White patients, suggesting that previously described racial disparities in survival among patients in GOG trials may have an novel etiology.

Lung cancer is the leader malignancy worldwide accounting 1.5 millions of deaths every year. In the United States the 5 year-overall survival is less than 20% for all the newly diagnosed patients. Cisplatin-based cytotoxic chemotherapy for unresectable or metastatic NSCLC patients in the first line of treatment, and docetaxel in the second line, have achieved positive results but with limited benefit in overall survival. Targeted therapies for EGFR and ALK mutant patients have showed better results when compared with chemotherapy, nevertheless most of patients will fail and need to be treated with chemotherapy if they still have a good performance status.Immunotherapy recently has become the most revolutionary treatment in solid tumors patients. First results in unresectable and metastatic melanoma patients treated with an anti CTLA-4 monoclonal antibody showed an unexpected 3-year overall survival of at least 25%.Lung cancer cells have multiple immunosuppressive mechanisms that allow to escape of the immune system and survive, however blocking CTLA-4 pathway with antibodies as monotherapy treatment have not achieved same results than in melanoma patients. PD-1 expression has been demonstrated in different tumor types, suggesting than PD-1 / PD-L1 pathway is a common mechanism used by tumors to avoid immune surveillance and favoring tumor growth. Anti PD-1 and anti PD-L1 antibodies have showed activity in non-small cell lung cancer patients with significant benefit in overall survival, long lasting responses and good safety profile, including naïve and pretreated patients regardless of the histological subtype. Even more, PD-1 negative expression patients achieve similar results in overall survival when compared with patients treated with chemotherapy. In the other side high PD-1 expression patients that undergo immunotherapy treatment achieve better results in terms of survival with lesser toxicity. Combining different immunotherapy treatments, combination of immunotherapy with chemotherapy or with targeted treatment are under research with some promising PRELIMINARY results in non-small cell lung cancer patients.This chapter attempts to summarize the development of immunotherapy treatment in non-small cell lung cancer patients and explain the results that have leaded immunotherapy as a new standard of treatment in selected NSCLC patients.

Purpose: In early-stage classical Hodgkin lymphoma, fluorodeoxyglucose positron emission tomography (PET)-computed tomography (CT) scans are performed routinely after chemotherapy, and the 5-point Deauville score is used to report the disease response. We hypothesized that other PET-CT parameters, considered in combination with Deauville score, would improve risk stratification. Methods and Materials: Patients treated for stage I to II Hodgkin lymphoma from 2003 to 2013, who were aged ≥18 years and had analyzable PET-CT scans performed before and after chemotherapy, were eligible. The soft tissue volume (STV), maximum standardized uptake value, metabolic tumor volume, and total lesion glycolysis were recorded from the PET-CTmore » scans before and after chemotherapy. Reductions were defined as 1 − (final PET-CT value)/(corresponding initial PET-CT value). The primary endpoint was freedom from progression (FFP). Results: For 202 patients treated with chemotherapy with or without radiation therapy, the 5-year FFP was 89% (95% confidence interval 85%-93%). All PET-CT parameters were strongly associated with the Deauville score (P<.001) and FFP (P<.0001) on univariate analysis. The Deauville score was highly predictive of FFP (C-index 0.89) but was less discriminating in the Deauville 1 to 4 subset (C-index 0.67). Therefore, we aimed to identify PET-CT parameters that would improve risk stratification for this subgroup (n=187). STV reduction was predictive of outcome (C-index 0.71) and was dichotomized with an optimal cutoff of 0.65 (65% reduction in STV). A model incorporating the Deauville score and STV reduction predicted FFP more accurately than either measurement alone in the Deauville 1 to 4 subset (C-index 0.83). The improvement in predictive accuracy of this composite measure compared with the Deauville score alone met statistical significance (P=.045). Conclusions: The relative reduction in tumor size is an independent predictor of outcome. Combined with the Deauville score, it might improve risk stratification and contribute to response-adapted individualization of therapy.« less

This retrospective study on early and locally advanced esophageal cancer was conducted to evaluate locoregional failure and its impact on survival by comparing involved field radiotherapy (IFRT) with elective nodal irradiation (ENI) in combination with concurrent chemotherapy. We assessed all patients with esophageal cancer of stages I-IV treated with definitive radiotherapy from June 2000 to March 2014. Between 2000 and 2011, ENI was used for all cases excluding high age cases. After Feb 2011, a prospective study about IFRT was started, and therefore IFRT was used since then for all cases. Concurrent chemotherapy regimen was nedaplatin (80 mg/m(2) at D1 and D29) and 5-fluorouracil (800 mg/m(2) at D1-4 and D29-32). Of the 239 consecutive patients assessed (120 ENI vs. 119 IFRT), 59 patients (24.7%) had stage IV disease and all patients received at least one cycle of chemotherapy. The median follow-up time for survivors was 34.0 months. There were differences in 3-year local control (44.8% vs. 55.5%, p = 0.039), distant control (53.8% vs. 69.9%, p = 0.021) and overall survival (34.8% vs. 51.6%, p = 0.087) rates between ENI vs. IFRT, respectively. Patients treated with IFRT (8 %) demonstrated a significantly lower risk (p = 0.047) of high grade late toxicities than with ENI (16%). IFRT did not increase the risk of initially uninvolved or isolated nodal failures (27.5% in ENI and 13.4% in IFRT). Nodal failure rates in clinically uninvolved nodal stations were not increased with IFRT when compared to ENI. IFRT also resulted in significantly decreased esophageal toxicity, suggesting that IFRT may allow for integration of concurrent systemic chemotherapy in a greater proportion of patients. Both tendencies of improved loco-regional progression-free survival and a significant increased overall survival rate favored the IFRT arm over the ENI arm in this study.

Ipilimumab is a fully human, anti-cytotoxic T-lymphocyte antigen-4 (CTLA-4) monoclonal antibody that has demonstrated antitumor activity in advanced melanoma. We evaluated the safety and efficacy of ipilimumab alone and in combination with dacarbazine (DTIC) in patients with unresectable, metastatic melanoma. Chemotherapy-naïve patients were randomized in this multicenter, phase II study to receive ipilimumab at 3 mg/kg every 4 weeks for four doses either alone or with up to six 5-day courses of DTIC at 250 mg/m(2)/day. The primary efficacy endpoint was objective response rate. Seventy-two patients were treated per-protocol (ipilimumab plus DTIC, n = 35; ipilimumab, n = 37). The objective response rate was 14.3% (95% CI, 4.8-30.3) with ipilimumab plus DTIC and was 5.4% (95% CI, 0.7-18.2) with ipilimumab alone. At a median follow-up of 20.9 and 16.4 months for ipilimumab plus DTIC (n = 32) and ipilimumab alone (n = 32), respectively, median overall survival was 14.3 months (95% CI, 10.2-18.8) and 11.4 months (95% CI, 6.1-15.6); 12-month, 24-month, and 36-month survival rates were 62%, 24% and 20% for the ipilimumab plus DTIC group and were 45%, 21% and 9% for the ipilimumab alone group, respectively. Immune-related adverse events were, in general, medically manageable and occurred in 65.7% of patients in the combination group versus 53.8% in the monotherapy group, with 17.1% and 7.7% ≥grade 3, respectively. Ipilimumab therapy resulted in clinically meaningful responses in advanced melanoma patients, and the results support further investigations of ipilimumab in combination with DTIC.

Purpose: There is an important need to improve the effectiveness of radio-chemotherapy (RTCT) for cervical cancer. The CXCL12/CXCR4 pathway can influence RT response by recruiting normal myeloid cells to the tumor microenvironment that in turn can exert radioprotective effects, and may promote metastases. The objective of this study was to explore the efficacy and toxicity of combining RTCT with CXCL12/CXCR4 inhibition in cervical cancer. Experimental Design: CXCR4 expression was measured in 115 patients with cervical cancer. Two primary orthotopic cervical cancer xenografts (OCICx) with different levels of CXCR4 expression were treated with RT (30 Gy: 15 daily fractions) and weekly cisplatin (4 mg/kg), with or without the CXCR4 inhibitor Plerixafor (5 mg/kg/day). The endpoints were tumor growth delay and lymph node metastases. Acute intestinal toxicity was assessed using a crypt cell assay. Results: There was a fivefold variation in CXCR4 mRNA expression in the patient samples, and good correlation between the expression in patients and in the xenografts. The combination of RTCT and Plerixafor produced substantial tumor growth delay and reduced lymph node metastases compared with RTCT alone in both of the xenograft models. There was a trend toward reduced acute intestinal toxicity with the addition of Plerixafor to RTCT. There were no changes in normal organ morphology to suggest increased late toxicity. Conclusions: This study demonstrates that the addition of Plerixafor to standard RTCT improves primary tumor response and reduces metastases in cervical cancer with no increase in toxicity. This combination warrants further investigation in phase I/II clinical trials. Clin Cancer Res; 23(5); 1242-9. ©2016 AACR . ©2016 American Association for Cancer Research.

Traditional Chinese Medicine (tcm) is used in China as part of the treatment for non-small-cell lung cancer (nsclc) and often includes prescription of herbal therapy based on syndrome differentiation. Studies of various Astragalus-based Chinese medicines combined with platinum-based chemotherapy in the treatment of lung cancer are popular in East Asia, particularly in China. The aim of the present study was to perform a systematic review and meta-analysis comparing platinum-based chemotherapy alone with platinum-based chemotherapy plus Astragalus-based Chinese botanicals, with and without prescription based on syndrome differentiation, as first-line treatment for advanced nsclc. We searched the Chinese Biomedical Literature database, the China National Knowledge Internet, the VIP Chinese Science and Technology Periodicals Database, PubMed, embase, the Cochrane databases, and abstracts presented at meetings of the American Society of Clinical Oncology, the World Conference on Lung Cancer, the European Society for Medical Oncology, and the Chinese Society of Clinical Oncology for all eligible studies. Endpoints were overall survival; 1-year, 2-year, and 3-year survival rates; performance status; overall response rate; and grade 3 or 4 adverse events. Subgroup analyses based on herbal formulae individualized using syndrome differentiation or on oral or injection patent medicines were performed using the Stata software application (version 11.0: StataCorp LP, College Station, TX, U.S.A.) and a fixed-effects or random-effects model in case of heterogeneity. Results are expressed as a hazard ratio (hr) or relative risk (rr), with corresponding 95% confidence intervals (cis). Seventeen randomized studies with scores on the Jadad quality scale of 2 or more, representing 1552 patients, met the inclusion criteria. Compared with platinum-based chemotherapy alone, the addition of Astragalus-based tcm to chemotherapy was associated with significantly increased overall survival (hr: 0.61; 95% ci: 0.42 to 0.89; p = 0.011); 1-year (rr: 0.73; 95% ci: 0.65 to 0.82; p < 0.001), 2-year (rr: 0.3344; 95% ci: 0.237 to 0.4773; p < 0.001), and 3-year survival rates (rr: 0.30; 95% ci: 0.17 to 0.53; p < 0.001); performance status (rr: 0.43; 95% ci: 0.34 to 0.55; p < 0.001); and tumour overall response rate (rr: 0.7982; 95% ci: 0.715 to 0.89; p < 0.001). Subgroup analyses indicated that Astragalus herbal formulae given based on syndrome differentiation were more effective than Astragalus-based oral and injection patent medicines. Side effects-including anemia, neutropenia, thrombocytopenia, fatigue, poor appetite, nausea, and vomiting-were significantly more frequent with platinum-based chemotherapy alone than when platinum-based chemotherapy was combined with Astragalus-based tcm. Astragalus-based Chinese botanical therapy, especially when based on syndrome differentiation, is associated with increased efficacy of platinum-based chemotherapy and decreased platinum-derived toxicities for patients with advanced nsclc.

The paper is to systematically evaluate the effect and safety of Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy for non-small cell lung cancer (NSCLC). Randomized controlled trials (RCTs) on Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy (experiment group) and chemotherapy alone group ( control group) were electronically retrieved from Medline, EMbase, Clinical Trials, Cochrane Library, CBM, CNKI, VIP, and Wanfang Data base. All trials were assessed for quality according to the Cochrane Reviewer's Handbook for Systematic Reviews of Intervention and then Meta-analysis was performed withRevMan5. 2 Software. A total of 43 RCTs (3433 patients) were included after screening and selecting. Results of Meta-analysis showed that: Objective remission rate (ORR): ORR of experimental group was about 20% higher than that of control group [RR = 1.23, 95% CI (1.11,1.35), P < 0.0001]. Disease control rate (DCR):DCR of SFI combined with first-line chemotherapy was 11% higher than that of first-line chemotherapy alone [RR = 1.11, 95% CI (1.07, 1.16), P < 0.000 01]. Life quality evaluated by Kosovan performance status (KPS) showed that: life quality improvement rate of experimental group was about twice of that in control group [RR = 2.02, 95% CI (1.81, 2.26), P < 0.000 01]. Toxic and side reaction analysis showed that: the incidence of side reactions in experimental group was about 50% lower than that in control group [RR = 0.59, 95% CI (0.53, 0.66), P < 0.000 01]. Immune function test showed that: the function of experimental group was 3.2 (standard deviations) times greater than that of control group [MD = 3.23, 95% CI (2.86, 3.60), P < 0.000 01]. We can see that SFI combined with first-line chemotherapy for NSCLC can increase objective efficacy, improve life quality, decrease toxic and side reactionsinduced by chemotherapy, and improve the immune functions. As most of the included studies in this systematic evaluation had poor quality, the evidence to support conclusion was weak, so it was necessary to conduct more multi-center clinical trials with high quality methods and rigorous design.
