    Almost half of the patients with muscle invasive disease already harbor at the time of their first diagnosis occult or distant metastases. Systemic disease has a poor prognosis with a long term survival of less than 10%. The administration of systemic chemotherapy aims to improve the course of locally advanced or metastatic disease.A survival benefit of 5% for patients receiving neoadjuvant and 9-11% using adjuvant chemotherapy is in the first scenario minimal, in the adjuvant setting to be noteworthy. The MVAC-schedule and the Gemcitabine/Cisplatin-combination chemotherapy have to be regarded as standard for induction chemotherapy. However, the 5-year survival rates with 15 or 13% are disappointing.Thus, prognostic factors gain importance since with their consideration significant differences in survival rates can be found. Hope is provided by a novel class of substances, the target-specific drugs, which selectively interfere with the cascade of steps involved in tumorigenesis.

    Systemic adjuvant chemotherapy can improve overall survival and reduce the incidence of distant metastases for patients with advanced colon cancer. This study aimed to investigate whether regional chemotherapy (given by intraperitoneal or intraportal methods) combined with systemic chemotherapy was more effective than was systemic chemotherapy alone in terms of survival and recurrence for patients with stage II-III colorectal cancer. The study also compared systemic chemotherapy with fluorouracil and folinic acid with that of fluorouracil and levamisole. During surgery, 753 patients with stage II-III colorectal cancer were randomly assigned to systemic chemotherapy alone (379 with fluorouracil and folinic acid, and 374 with fluorouracil and levamisole), and 748 to postoperative regional chemotherapy with fluorouracil followed by systemic chemotherapy with fluorouracil and folinic acid (n=368) or with fluorouracil and levamisole (n=380). Regional chemotherapy was given intraperitoneally (n=415) or intraportally (n=235) according to institution. The primary endpoint was 5-year overall survival. Secondary endpoints were 5-year disease-free survival and toxic effects. Analyses were by intention to treat. Median follow-up was 6.8 years (range 0.0-10.1). 5-year overall survival was 72.3% (95% CI 69.0-75.6) for patients assigned regional and systemic chemotherapy, compared with 72.0% (68.7-75.3) for those assigned systemic chemotherapy alone (hazard ratio [HR] 0.97 [0.81-1.15], p=0.69). 5-year overall survival for all patients assigned fluorouracil and levamisole was 72.0% (68.7-75.2) compared with 72.3% (69.0-75.6) for all those assigned fluorouracil and folinic acid (HR 0.98 [0.82-1.17], p=0.81). The hazard ratios for 5-year disease-free survival were 0.94 (0.80-1.10) for regional versus non-regional treatment, and 0.92 (0.79-1.08) for all fluorouracil and levamisole versus fluorouracil and folinic acid. Grade 3-4 toxic effects were low in all groups. Fluorouracil

    Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is the preferred treatment of peritoneal carcinomatosis (PC) of colorectal carcinoma. Patients with positive lymph node status have worse survival after CRS-HIPEC, which is probably due to higher rates of systemic failure. In this study, we analysed the effect of administration and timing of systemic chemotherapy on the outcome of lymph node positive colorectal carcinoma patients treated with CRS-HIPEC. A prospective database was reviewed to identify lymph node positive patients with PC treated with CRS-HIPEC within 1 year after primary tumour diagnosis between 2004 and 2012. Medical history of the patients was studied for the administration of perioperative systemic chemotherapy and follow-up. Outcome parameters were progression-free survival (PFS), overall survival (OS) and pattern of recurrence. Seventy-three patients treated with CRS-HIPEC for PC from lymph node positive colorectal carcinoma were identified. Fourteen patients received pre-CRS-HIPEC chemotherapy only, 32 patients underwent post-CRS-HIPEC chemotherapy only, 9 patients received chemotherapy both pre- and post-CRS-HIPEC and 16 patients did not receive any systemic chemotherapy. Of the 47 patients who did not receive pre-CRS-HIPEC chemotherapy, 11 (23%) did not receive any chemotherapy due to major postoperative complications. PFS and OS were significantly higher in patients who received systemic chemotherapy (PFS: median 15 versus 4 months, P = 0.024; OS: median 30 versus 14 months, P = 0.015), although this difference was attenuated after adjustment for major complications. Different chemotherapy timings did not differ significantly in either survival or recurrence patterns. In patients with PC from lymph node positive colorectal carcinoma, perioperative systemic chemotherapy is associated with increased OS and PFS, although this difference may be partly explained by the occurrence of major postoperative complication

    A 69-year-old man underwent right hemicolectomy for ascending colon cancer with liver metastases. Postoperative systemic chemotherapy did not reduce the metastases, and therefore, hepatic arterial infusion chemotherapy (HAI) was administered. The metastases decreased in size after 26 rounds of therapy, and the patient underwent resection. He is recurrence-free 63 months after the primary operation. A 57-year-old man underwent Hartmann's operation for sigmoid colon cancer with liver metastases. He underwent hepatic left lobe resection after metastases reduction by systemic chemotherapy. However, multiple liver metastases were detected 2 months later. Because the disease progressed despite the administration of systemic chemotherapy, HAI was utilized instead. The metastases decreased in size remarkably, and resection was performed. The patient is surviving 52 months after the primary operation while being continuously treated with HAI, resection, and systemic chemotherapy for re-recurrence. HAI is a potential alternative treatment for patients with colorectal liver metastases resistant to systemic chemotherapy.

    We have previously introduced electroretinography (ERG) as a proxy for visual function to monitor for retinal toxicity due to intra-arterial chemotherapy for retinoblastoma in young children. In this paper, we report ERG results for patients with retinoblastoma receiving initial treatment with systemic chemotherapy. Inclusion criteria were patients presenting with retinoblastoma at <3 months of age or <6.0 kg in weight, with large tumours not amenable to local laser treatment, cryotherapy or plaque brachytherapy. Patients received intravenous carboplatin 18.7 mg/kg every 3-5 weeks, contingent on recovery of blood counts, until they had grown sufficiently to receive intra-arterial chemotherapy. ERG was performed during examination under anaesthesia at monthly intervals, using contact lens electrodes and a hand-held ganzfeld stimulator. 30-Hertz flicker responses are reported. Four patients were treated for bilateral retinoblastoma. All eyes responded well to systemic chemotherapy. 30-Hertz flicker ERGs improved during treatment in all eyes, significantly in six of eight eyes, and at least in one eye of each patient. Effective systemic chemotherapy for retinoblastoma in children who are too small for intra-arterial chemotherapy is compatible with significant increases in ERG amplitudes, even in eyes presenting with extinguished ERGs. ERG signals may increase independent of resolution of retinal detachment.

    The authors present the history of two patients. The first patient, a 69-year-old woman was diagnosed with locally invasive triple negative breast cancer with pulmonary and cerebral metastases. Complete radiological remission of the clinically asymptomatic cerebral metastases was detected under systemic chemotherapy with carboplatin-docetaxel (75 mg/m(2)). Later, the patient received whole brain radiotherapy and a second line of chemotherapy. The overall survival was 20 months from the diagnosis of cerebral metastases with conservation of partial autonomy. The second patient, a 57-year-old woman was diagnosed as having hormone sensitive lobular breast cancer with leptomeningeal, lymphonodular and multiple osseal metastases. Before the appearance of the lymphonodular metastasis the patient received intrathecal methotrexate chemotherapy for the leptomeningeal carcinomatosis. Her neurological symptoms completely disappeared. At the onset of the lymphonodular metastasis systemic chemotherapy with ifosfamide (1000 mg/m(2), D1-3) - etoposide (100 mg/m(2), D1-3) was started allowing complete clinical remission of the lymphadenomegaly and stability of the asymptomatic neurological status. The overall survival was 13 months from the diagnosis of leptomeningeal carcinomatosis with conservation of autonomy. The two cases support potential efficacy of systemic chemotherapy for intracranial metastases of breast cancer. Orv. Hetil., 2016, 157(45), 1809-1813.

    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.

    Cancer has become one of the most difficult health challenges of our time, accounting for millions of deaths yearly. Systemic chemotherapy is the most common therapeutic approach; however, considerable limitations exist including toxicities to healthy tissues and low achievable drug concentrations at tumor sites. More than 85% of human cancers are solid tumors, which can greatly benefit from localized delivery. This approach allows for high drug concentrations at the target site, lower systemic toxicity, and extended drug exposure which may be beneficial for cell cycle-specific drugs. Polymers have been widely considered in the development of localized delivery systems. This review focuses on both natural and synthetic biodegradable polymers that have been explored for localized chemotherapy, exploring their advantages, disadvantages, and clinical potential while citing examples of their use in pre-clinical development.

    Primary central nervous system lymphoma (PCNSL) accounts for only 3% of brain tumors. It can involve the brain parenchyma, leptomeninges, eyes and the spinal cord. Unlike systemic lymphoma, durable remissions remain uncommon. Although phase III trials in this rare disease are difficult to perform, many phase II trials have attempted to define standards of care. Treatment modalities for patients with newly diagnosed PCNSL include radiation and/or chemotherapy. While the role of radiation therapy for initial management of PCNSL is controversial, clinical trials will attempt to improve the therapeutic index of this modality. Routes of chemotherapy administration include intravenous, intraocular, intraventricular or intra-arterial. Multiple trials have outlined different methotrexate-based chemotherapy regimens and have used local techniques to improve drug delivery. A major challenge in the management of patients with PCNSL remains the delivery of aggressive treatment with preservation of neurocognitive function. Because PCNSL is rare, it is important to perform multicenter clinical trials and to incorporate detailed measurements of long-term toxicities. In this review we focus on different chemotherapeutic approaches for immunocompetent patients with newly diagnosed PCNSL and discuss the role of local drug delivery in addition to systemic therapy. We also address the neurocognitive toxicity of treatment. PMID:21789140

    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

    We have evaluated the effectiveness of systemic chemotherapy for patients with extrahepatic metastasis from hepatocellular carcinoma. We examined the background, survival rates, median survival time and side effects of 15 cases in which systemic chemotherapy using carboplatin and 5-fluorouracil was done (chemotherapy group) and 59 cases in which chemotherapy was not done (non-chemotherapy group) out of a total of 74 cases of patients with extrahepatic metastasis from hepatocellular carcinoma. The prognoses of the 15 chemotherapy cases and the 59 non-chemotherapy cases were as follows: 66.0%, 33.3%, 20.0% at 6 months, 12 months, 18 months respectively for the chemotherapy cases and 44.0%, 18.2%, 7.1% respectively for the non-chemotherapy cases. Median survival periods were 10.7 months for the chemotherapy group and 5.1 months for the non-chemotherapy group. A significantly better prognosis of survival (p=0.037) was identified in the chemotherapy group and no serious side effects were observed. The present research preceded the approval of sorafenib. This systemic combination chemotherapy will provide an extended survival prognosis and is thus considered to be comparatively safe and effective in those patients.

    The aim of this study is to discuss the curative effect of introperitoneal hyperthermic perfusion chemotherapy(IHPC) combined with systemic neoadjuvant chemotherapy on the gastric cancer patients with peritoneal carcinomatosis. Sixty-four patients with gastric cancer and peritoneal carcinomatosis who were hospitalized in the Department of Gastrointestinal Surgery of First Hospital of Jilin University from December 2006 to December 2013. After peritoneal carcinomatosis was confirmed during laparoscopic exploration, FOLFOX6 (oxaliplatin and calcium folinate and 5-Fu) was performed for systemic chemotherapy. One course was 14 days and a complete treatment includes four courses. At the same time, patients underwent peritoneal catheter insertion and received IHPC(5-Fu 1 500 mg/m(2) and Cisplatin 35 mg/m(2) were added into 0.9% NaCl solution 2 000 ml, the infusion velocity was 35-45 ml/min, infusion time was 45-60 minutes, the temperature was controlled to 41°C). A comprehensive evaluation was taken after the fourth course of treatment before operation. Further surgical therapy was performed according to the assessment result. Sixty-four patients received IHPC combined with systemic chemotherapy. Thirty-two patients(50.0%) had partial response, 18(28.1%) stable disease, and 14(21.9%) progressive disease after chemotherapy. No severe complications or death occurred during the neoadjuvant chemotherapy. Thirty-two patients(50.0%) received radical resection, 10(15.6%) palliative operation, and another 22 patients(37.4%) didn't comply with inclusion criteria of operation. Patients receiving operation had a median survival time of 678 days, which was significantly longer than patients without operation, with a median survival time of 251(χ(2)=23.34, P=0.02). IHPC combined with systemic chemotherapy is an effective therapeutic method for gastric cancer patients with peritoneal carcinomatosis in terms of reducing preoperative tumor load and achieving radical resection.

    With the developments in medical information systems and the widespread establishment of medical information systems that include computerized order communication systems (OCSs), there has been an increase in the establishment of computerized chemotherapy order systems. In this study, we aim to design an improved computerized provider order entry (CPOE) system that integrates a chemotherapy ordering system that can issue a customized order in response to a provider's diverse chemotherapy prescription needs with an automated issuance of dosage, treatment schedule, and treatment method. We expect the newly designed system to be able to prevent the common errors in complex chemotherapy ordering systems and reduce the time required for ordering.

    The potential benefit of adjuvant hepatic arterial infusional floxuridine (HAI-FUDR) in addition to modern systemic chemotherapy using oxaliplatin or irinotecan remains unknown for patients with resected liver-confined colorectal metastases (CRLM). The principle aim of this study was to compare outcomes in patients receiving modern systemic chemotherapy with or without HAI-FUDR. Between 2000 and 2005, 125 patients underwent resection of CRLM followed by adjuvant HAI-FUDR plus dexamethasone (Dex) and concurrent systemic chemotherapy including oxaliplatin or irinotecan. These patients were compared retrospectively to 125 consecutive patients who received modern systemic chemotherapy alone after liver resection. The median follow-up for all patients was 43 months. There were no differences in clinical risk score, disease-free interval, size of largest CRLM, number of CRLM, or prehepatectomy CEA level between the 2 groups. Adjuvant HAI-FUDR was associated with an improved overall and liver recurrence-free survival (liver RFS) and disease-specific survival (DSS). For the adjuvant HAI-FUDR group, the 5-year liver RFS, overall RFS, and DSS were 75%, 48%, and 79%, respectively, compared to 55%, 25%, and 55% for the systemic alone group (P < 0.01). On multivariate analysis, adjuvant treatment including HAI-FUDR was independently associated with improved liver RFS (HR = 0.34), overall RFS (HR = 0.65), and DSS (HR = 0.39), P < 0.01. Adjuvant HAI-FUDR combined with modern systemic chemotherapy is independently associated with improved survival compared to adjuvant systemic chemotherapy alone. A randomized clinical trial between these 2 regimens is justified.

    Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new treatment that applies chemotherapeutic drugs into the peritoneal cavity as an aerosol under pressure. It improves local bioavailability of chemotherapeutic drugs as compared with conventional intraperitoneal chemotherapy. It has been proved to be safe and feasible if performed as an exclusive treatment in patients affected by peritoneal carcinomatosis. The first results in patients treated with PIPAC associated with systemic chemotherapy are presented. Between June 2015 and February 2016, 57 PIPAC applications with oxaliplatin or cisplatin + doxorubicin every 6 weeks at 37 °C and 12 mmHg for 30 min were performed. Forty PIPAC procedures performed in 14 patients were included in this study; thirteen patients were undergoing systemic chemotherapy with a wash-out interval of at least 2 weeks before and 1 week after each PIPAC. Safety, tolerability, and postoperative complications were assessed by collection of adverse events according to the Common Terminology Criteria for Adverse Events (CTCAE) 2. Forty PIPAC administrations were performed in 14 patients with no major perioperative complications. CTCAE grades 1 and 2 were observed after six and eight procedures, respectively, for abdominal pain and nausea. Renal and hepatic functions were not impaired; no cumulative renal toxicity was observed after repeated PIPAC procedures in association with systemic chemotherapy. These preliminary data show that the association of PIPAC and systemic chemotherapy does not induce significant hepatic and renal toxicity. It allows inclusion of patients with extraperitoneal disease or at a high risk of developing it. Further studies are needed to assess whether this combination therapy could become part of the standard treatment for peritoneal carcinomatosis.

    Given the growing body of evidence supporting the benefit of primary tumor control for a wide range of metastatic malignancies, we hypothesized that chemotherapy plus radical nephroureterectomy (RNU) is associated with an overall survival (OS) benefit compared to chemotherapy alone for metastatic upper tract urothelial carcinoma (mUTUC). Within the National Cancer Data Base (2004-2012), we identified 398 (38.4%) and 637 (61.6%) patients who received chemotherapy plus RNU and chemotherapy alone, respectively. Inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier curves showed that 3-yr OS was 16.2% (95% confidence interval [CI] 12.1-20.3) for chemotherapy plus RNU and 6.4% (95%CI 4.1-8.7) for chemotherapy alone (p<0.001). In IPTW-adjusted Cox regression analysis, chemotherapy plus RNU was associated with a significant OS benefit (hazard ratio 0.70, 95% CI 0.61-0.80; p<0.001). Despite the usual biases related to the observational study design, our findings show a net OS benefit for fit patients who received chemotherapy plus RNU for mUTUC relative to their counterparts treated with chemotherapy alone. We examined the role of radical nephroureterectomy in addition to systemic chemotherapy for metastatic upper tract urothelial carcinoma. We found that such treatment may be associated with an overall survival benefit compared to chemotherapy alone in fit patients. Copyright © 2016 European Association of Urology.

    Intrahepatic cholangiocarcinoma (ICC) is associated with poor survival. This study compared the outcomes of patients with unresectable ICC treated with hepatic arterial infusion (HAI) plus systemic chemotherapy (SYS) with the outcomes of patients treated with SYS alone. Consecutive patients with ICC were retrospectively reviewed. Clinicopathologic data were reviewed. Survival rates were compared by Kaplan-Meier analysis and log-rank testing. Between January 2000 and August 2012, 525 patients with ICC were evaluated at Memorial Sloan Kettering Cancer Center, and 236 patients with unresectable tumors (locally advanced or metastatic) were analyzed. Disease was confined to the liver in 104 patients, who underwent treatment with combined HAI and SYS (n = 78 or 75%) or SYS alone (n = 26 or 25%). The response rate in the combined group was better than the rate in the group receiving SYS alone, although this did not reach statistical significance (59% vs 39%, P = .11). Overall survival for the combined group was longer than overall survival for the patients who received SYS alone (30.8 vs 18.4 months, P < .001), and this difference was maintained when patients with portal lymph node disease were included in the survival analysis (29.6 months with HAI and SYS [n = 93] vs 15.9 months with SYS [n = 74], P < .001). Eight patients who initially presented with unresectable tumors responded enough to undergo complete resection and had a median overall survival of 37 months (range, 10.4-92.3 months). In patients with unresectable ICC confined to the liver or with limited regional nodal disease, a combination of SYS and HAI chemotherapy is associated with greater survival than SYS alone.

    The aim of the study was to evaluate the efficacy and safety of intratumoral chemotherapy with paclitaxel liposome combined with systemic chemotherapy as induction therapy in clinical stage III unresectable non-small cell lung cancer (NSCLC). Between January 2011 and July 2014, 48 patients, stage III, performance status 0-1, with unresectable clinical stage IIIA or IIIB NSCLC suitable for definitive radiation treatment, were included in the study. Patients with T3N1M0 and T4 (ipsilateral lung nodules) N0-1M0 were not included. Patients were given 3 cycles of chemotherapy every 3 weeks. Carboplatin (AUC5 by i.v. on day 1) and gemcitabine (i.v. 1,000 mg/m(2) on days 1 and 8) were administered. Paclitaxel liposome was injected at 1-3 mg/ml concentration into the tumor lesion by computed tomography-guided percutaneous fine-needle intratumoral injection and proven malignant lymph nodes according to pretreatment histological/cytological results by endobronchial ultrasound drug delivery with a needle on day 1 and day 8. Toxicity was assessed on days 8 and 22 in each cycle. Overall response rate (ORR) evaluation was performed at the end of cycle 3. Out of the 48 enrolled patients, 28 were males and 20 females, 19 patients had stage IIIA and 29 stage IIIB NSCLC. Thirty-six partial responses and two complete responses were observed, for an ORR of 81 %. The most frequent G3-G4 toxicity included neutropenia (in 15 % of cases), hypertransaminasemia (6 %), and diarrhea (4 %). A median PFS of 16.5 months (95 % CI 13.7-19.2) and median OS of 23.2 months (95 % CI 20.0-26.3) were observed. Eleven stage IIIA patients underwent surgery, for a resection rate of 58 %. Intratumoral chemotherapy with paclitaxel liposome combined with systemic chemotherapy demonstrated a considerable disease response and resection rate, with acceptable toxicity.

    The benefit of pre-operative chemotherapy in patients with resectable colorectal liver metastases (CRLM) remains ill defined. We sought to evaluate the impact of peri-operative systemic chemotherapy timing on outcome following resection of CRLM. 676 patients who underwent surgery for CRLM were identified from two hepatobiliary center databases. Data were collected and analyzed utilizing multivariate, matched, and propensity-score analyses. Median number of metastases was 2 and median tumor size was 3.3 cm. 334 patients (49.4%) received pre-operative chemotherapy while 342(50.6%) did not. Surgical treatment was resection only (n = 555; 82.1%; minor hepatectomy, n = 399; 59.1%). While there was no difference in morbidity following minor liver resection (pre-operative chemotherapy: 17.9% versus no pre-operative chemotherapy: 16.5%; P = 0.72), morbidity was higher after major hepatic resection (pre-operative chemotherapy: 23.1% versus no pre-operative chemotherapy: 14.2%; P = 0.06). Patients treated with pre-operative chemotherapy had worse 5-year survival (43%) as compared to patients not treated with pre-operative chemotherapy (55%)(P = 0.009). Controlling for baseline characteristics, pre-operative chemotherapy was not associated with outcome on multivariate (HR = 1.04, P = 0.87) or propensity-score analysis (HR = 1.40, P = 0.12). Pre-operative chemotherapy was associated with a trend toward increased morbidity among patients undergoing a major hepatic resection. Receipt of pre-operative chemotherapy was associated with neither an advantage nor disadvantage in terms of long-term survival. Copyright © 2011 Wiley Periodicals, Inc.

    Marginal statistical evidence of efficacy of adjuvant and/or perioperative chemotherapy after resection of colorectal metastases exists, but formal recommendations are still lacking. The present study evaluated the adjuvant systemic chemotherapy after the first resection of liver and lung colorectal cancer metastases. We retrospectively reviewed data of 181 consecutive unselected patients with R0 resection of colorectal metastases treated simultaneously at 2 institutions from 1997 to 2004. Patients > 75 years old, with an Eastern Cooperative Oncology Group Performance Status Score ≥ 2 or unfit for adjuvant chemotherapy were excluded from the analysis. The decision on chemotherapy after surgery was left to the patient in the absence of conclusive data on the efficacy of adjuvant chemotherapy in this setting. A total of 151 patients (131 with liver metastases, 20 with lung metastases), 78 of whom underwent adjuvant chemotherapy, were evaluable for disease-free survival (DFS) and overall survival. The main prognostic factors for DFS after resection of colorectal cancer metastases were investigated in univariate and multivariate analyses. At the univariate analysis, the number of resected lesions, lesion volume, disease-free interval and adjuvant systemic chemotherapy were the only significant prognostic factors. At multivariate analysis, only adjuvant chemotherapy and disease-free interval were independent prognostic factors (hazard ratios 1.66 and 1.62, respectively). The median DFS of patients who underwent systemic adjuvant chemotherapy was 16 months compared with 9.7 months for patients with observation alone (hazard ratio 1.56). Estimated 5-year DFS was 17.4% and 10.5% for treated and untreated patients, respectively. Adjuvant chemotherapy after metastasectomy in patients with colorectal cancer showed a significant benefit for DFS. Copyright © 2013 Elsevier Inc. All rights reserved.

    Cholangiocarcinomas (CCA) are rare tumors of the liver with poor prognosis. The standard of care in patients with unresectable tumors or metastatic disease is combination chemotherapy (CT) with gemcitabine and cisplatin. Targeted therapies inhibiting EGFR, VEGF, MEK and others are broadly tested in CCA but to date, the existing data from randomized and nonrandomized trials do not justify the application of small molecules outside of clinical trials. In clinical practice, many patients receive second-line CT after failure of gemcitabine/cisplatin, although there is so far no evidence to support second-line CT. This review summarizes current chemotherapy protocols and ongoing studies, including conventional chemotherapy and targeted therapies. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Systemic chemotherapy has been relatively ineffective in the treatment of malignant brain tumors even though systemic chemotherapy drugs are small molecules that can readily extravasate across the porous blood-brain tumor barrier of malignant brain tumor microvasculature. Small molecule systemic chemotherapy drugs maintain peak blood concentrations for only minutes, and therefore, do not accumulate to therapeutic concentrations within individual brain tumor cells. The physiologic upper limit of pore size in the blood-brain tumor barrier of malignant brain tumor microvasculature is approximately 12 nanometers. Spherical nanoparticles ranging between 7 nm and 10 nm in diameter maintain peak blood concentrations for several hours and are sufficiently smaller than the 12 nm physiologic upper limit of pore size in the blood-brain tumor barrier to accumulate to therapeutic concentrations within individual brain tumor cells. Therefore, nanoparticles bearing chemotherapy that are within the 7 to 10 nm size range can be used to deliver therapeutic concentrations of small molecule chemotherapy drugs across the blood-brain tumor barrier into individual brain tumor cells. The initial therapeutic efficacy of the Gd-G5-doxorubicin dendrimer, an imageable nanoparticle bearing chemotherapy within the 7 to 10 nm size range, has been demonstrated in the orthotopic RG-2 rodent malignant glioma model. Herein I discuss this novel strategy to improve the effectiveness of systemic chemotherapy for the treatment of malignant brain tumors and the therapeutic implications thereof. PMID:19723323

    Substantial progress has been made in the multidisciplinary management of primary breast cancer during the last 30 years. Adjuvant chemotherapy has been shown to significantly reduce the annual risk of cancer recurrence and mortality, and these effects persist even 15 years after diagnosis. Combination chemotherapy is superior to single-agent therapy and anthracycline-containing regimens. Those that combine an anthracycline with 5-fluorouracil and cyclophosphamide are more effective than regimens without an anthracycline. Six cycles of a single regimen appear to provide optimal benefit. Dose reductions below the standard range are associated with inferior results. Dose increases that require growth factor or hematopoietic stem cell support are under investigation; at this time, the existing results provide no compelling reason to use this strategy outside a clinical trial. Regimens using fixed crossover designs with two non-cross-resistant regimens are being evaluated. The addition of a taxane to anthracycline-containing regimens is currently under intense scrutiny, and preliminary analysis of the first three clinical trials has shown encouraging, albeit not compelling, results. For patients with estrogen receptor-positive breast cancer, the sequential administration of chemotherapy and 5 years of tamoxifen therapy provides additive benefits. No compelling evidence exists to combine ovarian ablation with chemotherapy. Most side effects and toxic effects are self-limited, although premature menopause requires monitoring and preventive interventions to preserve bone mineral density. The small risk of acute leukemia is of concern, and additional research to develop safer regimens is clearly indicated. The overall effect of optimal local/regional treatment combined with an anthracycline-containing adjuvant chemotherapy and a taxane (and, for patients with estrogen receptor-positive tumors, 5 years of tamoxifen therapy) is a greater than 50% reduction in annual risks of

    Background Optimal treatment for recurrent primary central nervous system lymphomas (PCNSLs) has not been defined yet and there is no general consensus about the salvage chemotherapy after high-dose methotrexate (HD-MTX)-based chemotherapy. The purpose of the present study was to evaluate the efficacy and safety of procarbazine, lomustine, and vincristine (PCV) chemotherapy for recurrent PCNSLs. Methods We reviewed eight immunocompetent patients (five males/three females, mean age: 56 years) who received salvage PCV chemotherapy (procarbazine 60 mg/m2, days 8 through 21: CCNU 110 mg/m2, day 1: vincristine 2 mg, days 8 and 28) for recurrent PCNSL and two patients switched to PCV chemotherapy due to severe adverse effects of HD-MTX chemotherapy. Radiologic responses, survival, and adverse effects were analyzed. Results Of the eight recurrent PCNSLs, three patients (37.5%) showed radiologic complete response, one patient (12.5%) showed partial response, and four patients (50%) showed progressive disease after PCV chemotherapy. Median progression free survival (PFS) from the first administration of PCV to relapse or last follow-up was 7 months (range 5-32 months) and median overall survival was 8 months (range 2-41 months). The two patients who switched to PCV chemotherapy showed PFS of 9 and 5 months from the beginning of PCV to relapse. The common side effects were thrombocytopenia, neutropenia, and peripheral neuropathy. There were 4 grade III or IV myelo-suppression, but no fatal complications, including severe hemorrhage or infection, were observed. Conclusion Salvage PCV chemotherapy has a moderate anti-lymphoma activity for recurrent PCNSLs after the HD-MTX-based chemotherapy with tolerable toxicity. PMID:26605261

    A difficult balance exists in the use of cancer chemotherapy in which the cytotoxic medicine must act on the cancer without causing neutropenic fever, a condition that is caused by over-suppression of the immune system. An improved understanding of dosing strategies as well as the use of medications to support the immune system has helped to reduce the likelihood of an admission for neutropenic fever following cancer chemotherapy. Therefore, as with any drug therapy, chemotherapy administration that is temporally associated with an unexpected hospitalization for neutropenia is an adverse drug event (ADE). Analogous to other informatics research to monitor and address the occurrence of ADEs, this work develops and validates the information systems infrastructure necessary to detect the occurrence of and analyze the factors contributing to chemotherapy associated ADEs.

  15. Osteogenic Sarcoma: Systemic Chemotherapy Options for Localized Disease.

    Treatment for osteosarcoma, the most common malignant tumor of bone in children and adolescents, has not changed in decades. Treatment is multimodal, employing neoadjuvant chemotherapy followed by aggressive and complete surgical resection to achieve negative margins and a prolonged course of adjuvant chemotherapy. The primary tumor is usually successfully managed via surgery, but micrometastases are likely present in most patients at diagnosis. Death is the result of tumor recurrence in the lungs or more rarely in other bones despite aggressive treatment regimens and is likely attributable to innate resistance to chemotherapy. Better therapies are desperately needed. The three most active agents-high-dose methotrexate, doxorubicin, and cisplatin-commonly referred to as "MAP," form the backbone of therapy. After 2 cycles of MAP, surgical resection is performed of all sites of disease if possible. Histologic response following neoadjuvant chemotherapy is prognostic in non-metastatic osteosarcoma, but augmentation of adjuvant therapy for poor responders with additional agents (ifosfamide, etoposide) has not improved outcome. Inclusion of immunotherapy into treatment regimens is promising. Specifically, liposome-encapsulated muramyl tripeptide phosphatidylethanolamine (L-MTP-PE), a macrophage and monocyte activator, improved 10-year overall survival for patients with localized disease, with a similar pattern of response in patients with metastatic disease. L-MTP-PE (mifamurtide) is approved and in widespread use in Europe and elsewhere but has not been approved for use by the Federal Drug Administration in the USA. Identifying novel targeted therapies to improve outcomes for patients with osteosarcoma remains an area of active research.

    The real cost of medical consumption was compared with the proportion of medication consumption of (the) GHM n(o) 681 (homogeneous group of patients, chemotherapy for cancer in day care) in the French case mix system (PMSI). For those patients in our thoracic oncology unit (Sainte-Marguerite Hospital, Marseille, France), the real medication cost was calculated from prices paid by the hospital, then compared to the expected expenditures for the medication consumption of the GHM 681, i.e. 678 French francs (24.1% of the 225 ISA points (synthetic activity index)). Over a period of 2 months in 1998, 87 patients (mean age 63 +/- 11) had 194 chemotherapy sessions in day care, with multi-drug therapy in 38 cases. Vinorelbine or gemcitabine represented 81% of the single drug chemotherapy. In 84% of the single drug and 76% of the multi-drug chemotherapy, the real cost of medication consumption was above the allocated budget. The mean cost for single drug chemotherapy was 1722 FF and 2920 FF for multi-drug chemotherapy. The budget allocated by the PMSI shows a deficit in the most cases. To avoid a restriction in the use of some drugs, it appears that the French system of budget evaluation needs to be improved.

    Systemic chemotherapy for patients with metastatic gastric cancer (MGC) is generally palliative, although some patients experience long-term survival after treatment. Thus, we identified clinical characteristics that are associated with long-term survival of patients with MGC after palliative chemotherapy. We retrospectively reviewed 514 MGC patients who received systemic chemotherapy at our institution from 2001 to 2008. To identify clinical predictors of survival beyond 2 years, multivariate logistic regression analyses were performed, and 5-year survival rates were estimated among MGC patients following chemotherapy. Among 514 patients, 96 (19%) and 16 (3%) survived beyond 2 and 5 years, respectively, and performance status of 0 or 1 (odds ratio [OR]=3.39; p=0.01), previous gastrectomy (OR=1.86; p=0.01), single metastatic site (OR=1.80; p=0.03), and normal alkaline phosphatase levels (OR=2.81; p<0.01) were identified as independent predictors of long-term survival. Of the 16 5-year survivors, six were alive at the end of the study and showed no evidence of disease despite cessation of chemotherapy. The present data demonstrate distinct clinical characteristics that are associated with long-term survival of MGC patients, and indicated that palliative chemotherapy can be curative in highly selected patients.

  18. Oral manifestations of systemic chemotherapy and their management.

    Many antineoplastic drugs in use now have cytotoxic side effects that also manifest in the oral cavity or influence dental management. Chemotherapeutic agents that have a high potential for precipitating oral mucosal damage and bone marrow depression are methotrexate, cyclophosphamide, daunorubicin, doxorubicin hydrochloride, 5-fluorouracil, bleomycin, nitrogen mustard, cytosine-arabinoside, 6-mercaptopurine, busulfan, and L-phenylalanine mustard. Mucositis may lead to neglected oral hygiene, which in turn may cause a chain reaction of local infections, bleeding, and septicemia in myelosuppressed patients. Preventive oral care before chemotherapy and active oral care during therapy are necessary for compromised patients. A protocol for oral care is described.

    The goal of the study was to compare the efficacy and safety of sorafenib with those of systemic cytotoxic chemotherapy. Sorafenib treatment has shown to improve the survival in patients with advanced hepatocellular carcinoma (HCC) when compared with placebo. However, whether sorafenib controls advanced-stage HCC better than systemic cytotoxic chemotherapy has not been elucidated. We retrospectively reviewed the medical records of 220 patients with measurable advanced HCC who had not received systemic treatment previously between January 2007 and April 2012. Among these patients, 78 had been treated with sorafenib. Another 14 patients who were treated with a 4-weekly regimen of adriamycin, cisplatin, and capecitabine were included as the historical control group for comparison. The median overall survival, the progression-free survival, response rates, and safety profiles were evaluated. Baseline characteristics were similar between the treatment groups. The median overall survival was 7.2 months [95% confidence interval (CI), 5.6-8.8] in the sorafenib group and 11.2 months (95% CI, 8.1-14.2) in the cytotoxic chemotherapy group (P=0.10). The median progression-free survival was 3.2 months (95% CI, 2.2-4.3) in the sorafenib group and 5.9 months (95% CI, 3.6-8.2) in the cytotoxic chemotherapy group (P=0.07). The deterioration of liver function and neutropenia were the most frequent serious adverse events in the sorafenib and the systemic chemotherapy group. Although a direct head-to-head comparison could not be done, there were some patients who showed a good response to systemic cytotoxic chemotherapy. Further assessment is necessary to study the role of chemotherapy in patients who are intolerant or intractable to sorafenib.

    Endoscopic duodenal stenting has recently been proposed as a substitute for surgical gastrojejunostomy for the treatment of gastric outlet obstruction. We aimed to evaluate the efficacy and safety of duodenal stenting followed by systemic chemotherapy for patients with advanced pancreatic cancer with gastric outlet obstruction. This was a single-center, retrospective cohort study, conducted at an academic medical center, of 71 patients with advanced pancreatic cancer and gastric outlet obstruction (mean age: 67.6 years; range: 31-92 years) who underwent duodenal stenting with or without subsequent chemotherapy. Overall survival, duration of oral intake of foods, the rate of introduction of chemotherapy, progression-free survival, and adverse events were evaluated. Stent placement was technically successful in 69 (97%) patients. Thirty-six (51%) patients were treated with chemotherapy: 17 with gemcitabine alone, 15 with S-1 alone, 3 with FOLFIRINOX, and 1 with paclitaxel. Median progression-free survival and overall survival after chemotherapy were 2.6 months (95% confidence interval: 1.3-3.9 months) and 4.7 months (95% confidence interval: 2.6-6.8 months), respectively. Cases of grade 3 anemia were frequently observed during chemotherapies following duodenal stenting (32%). Tumor stage, performance status, neutrophil-to-lymphocyte ratio, and introduction of chemotherapy were independent prognostic factors for survival (hazard ratios of 3.73, 2.21, 2.69, and 1.85 with p-values of <0.001, 0.010, <0.001, and 0.045, respectively). The findings of this study suggest that endoscopic duodenal stenting is an advantageous treatment in advanced pancreatic cancer patients with gastric outlet obstruction regarding its safety and smooth conduction of subsequent chemotherapies.

    In this paper we study the global dynamics of a cancer chemotherapy system presented by de Pillis et al. (2007). This mathematical model describes the interaction between tumor cells, effector-immune cells, circulating lymphocytes and chemotherapy treatment. By applying the localization method of compact invariant sets, we find lower and upper bounds for these three cells populations. Further, we define a bounded domain in R+,04 where all compact invariant sets of the system are located and provide conditions under which this domain is positively invariant. We apply LaSalle's invariance principle and one result concerning two-dimensional competitive systems in order to derive sufficient conditions for tumor clearance and global asymptotic stability of the tumor-free equilibrium point. These conditions are computed by using bounds of the localization domain and they are given in terms of the chemotherapy treatment. Finally, we perform numerical simulations in order to illustrate our results.

    The use of systemic chemotherapy after resection remains controversial in patients with resectable metachronous pulmonary metastases from colorectal cancer (CRC). This retrospective study compared systemic chemotherapy with observation alone after resection of pulmonary metastases from CRC. Between 2001 and 2015, 91 patients with metachronous pulmonary metastases underwent curative surgical resection at five centers. Patients with stage IV at diagnosis were excluded. Overall survival (OS) was defined as the time from pulmonary resection until death. The disease-free interval (DFI) was defined as the time from pulmonary resection until recurrence or death. Among the 91 patients, 63 were in the chemotherapy group, while 28 were in the observation alone group. The characteristics were similar between the two groups, except for the carcinoembryonic antigen level after pulmonary metastases and the use of adjuvant treatment after resection of the primary tumor. With a median follow-up duration of 46 months (11-126), the estimated 5-year DFI and OS rates were 32.8 and 61.4%, respectively. The chemotherapy following pulmonary resection was not significantly associated with the DFI (p = 0.416) and OS (p = 0.119). Systemic chemotherapy after pulmonary resection was not found to have a significant effect on survival.

    Novel multidisciplinary treatment combined with neoadjuvant intraperitoneal-systemic chemotherapy protocol (NIPS) and peritonectomy was developed. Ninety-six patients were enrolled. Peritoneal wash cytology was performed before and after NIPS through a port system. Patients were treated with 60 mg/m2 of oral S-1 for 21 days, followed by a 1-week rest. On days 1, 8, and 15, 30 mg/m2 of Taxotere and 30 mg/m2 of cisplatin with 500 mL of saline were introduced through the port. NIPS is done 2 cycles before surgery. Three weeks after NIPS, 82 patients were eligible to intend cytoreductive surgery (CRS) by gastrectomy + D2 dissection + periotnectomy to achieve complete cytoreduction. Sixty-eight patients showed positice cytology before NIPS, and the positive cytology results became negative in 47 (69%) patients after NIPS. Complete pathologic response on PC after NIPS was experienced in 30 (36.8%) patients. Stage migration was experienced in 12 patients (14.6%). Complete cytoreduction was achieved in 58 patients (70.7%). By the multivariate analysis, complete cytoreduction and pathologic response became a significantly good survival. However the high morbidity and mortality, stringent patient selection is important. The best indications of the therapy are patients with good pathologic response and PCI ≤ 6, which are supposed to be removed completely by peritonectomy. PMID:22900159

    The aim was to evaluate the feasibility and the effectiveness of neoadjuvant systemic chemotherapy followed by cytoreductive surgery (CRS), hyperthermic intraperitoneal chemotherapy (HIPEC) and early postoperative intraperitoneal chemotherapy (EPIC) in patients with peritoneal carcinomatosis (PC) from gastric cancer. Eighteen patients (median age 57 years, range 38-74) were scheduled for three months' neoadjuvant systemic chemotherapy followed by CRS + HIPEC + EPIC. At the time of surgery, the peritoneal tumor burden was extensive with tumor growth on the entire peritoneal cavity. Only eight patients received the entire treatment and OS was 14.3 months (range 6.1-34.3, 95% CI 6.6-20.3). Six patients had macroscopically radical (CC0) surgery and for this subgroup OS was 19.1 months (range 6.1-34.3, 95% CI 6.9-27.1). Postoperative 90-day mortality was 10% (one patient) and the perioperative grades II-IV adverse events (AE) rate was 62.5%. Neoadjuvant chemotherapy followed by CRS + HIPEC + EPIC does not seem to be associated with prolonged OS in patients with extensive PC growth from gastric cancer unless macroscopically radical surgery is achieved. However, morbidity from this treatment is considerable and it cannot be recommended for routine care until a prospective randomized trial has been performed.

    Central nervous system (CNS)-directed chemotherapy is delivered for the treatment of childhood acute lymphoblastic leukaemia (ALL). Figurative language deficits have been described in children following CNS-directed chemotherapy; however, comprehensive analysis of figurative interpretation errors, potentially providing clinical utility to assist with intervention planning, has never been performed. The present study aimed to compare the figurative language skills of seven children treated with CNS-directed chemotherapy for ALL before the age of 6 years (mean age at diagnosis 3 years 10 months) and a matched control group of children, using the Test of Language Competence-Expanded Edition (TLC-E) Figurative Language sub-test. It was hypothesised that the children treated with CNS-directed chemotherapy would demonstrate a decreased performance in and an alternative method of interpreting figurative language. The results suggest no negative effects of CNS-directed chemotherapy on figurative language. There were no statistically significant differences between groups for TLC-E Figurative Language sub-test composite scores and picture component errors, nor were there clinically significant differences observed from descriptive comparisons of individual case data and error analysis. As these skills continue to emerge beyond childhood, the need to monitor skill development in ALL survivors beyond childhood is highlighted.

    This study analyzed outcomes of systemic chemotherapy for advanced neuroendocrine carcinoma (NEC) of the digestive system. Clinical data from 258 patients with unresectable or recurrent NEC of the gastrointestinal tract (GI) or hepato-biliary-pancreatic system (HBP), who received chemotherapy, were collected from 23 Japanese institutions and analyzed retrospectively. Patients had primary sites in the esophagus (n = 85), stomach (n = 70), small bowel (n = 6), colorectum (n = 31), hepato-biliary system (n = 31) and pancreas (n = 31). Median overall survival (OS) was 13.4 months the esophagus, 13.3 months for the stomach, 29.7 months for the small bowel, 7.6 months for the colorectum, 7.9 months for the hepato-biliary system and 8.5 months for the pancreas. Irinotecan plus cisplatin (IP) and etoposide plus cisplatin (EP) were most commonly selected for GI-NEC and HBP-NEC. For patients treated with IP/EP (n = 160/46), the response rate was 50/28% and median OS was 13.0/7.3 months. Multivariate analysis among patients treated with IP or EP showed that the primary site (GI vs HBP; hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.35-0.97) and baseline serum lactate dehydrogenase levels (not elevated vs elevated; HR 0.65, 95% CI 0.46-0.94) were independent prognostic factors for OS, while the efficacy of IP was slightly better than for EP (HR 0.80, 95% CI 0.48-1.33; P = 0.389). IP and EP are the most common treatment regimens for NEC of the digestive system. HBP primary sites and elevated lactate dehydrogenase levels are unfavorable prognostic factors for survival. A randomized controlled trial is required to establish the appropriate chemotherapy regimen for advanced NEC of the digestive system.

    The identification of responders is an important issue in chemotherapy for metastatic colorectal cancer (mCRC). 'Deepness of response' (DpR), defined as the maximum rate of reduction from the initial tumor burden, was recently proposed as a novel hypothetical parameter associated with overall survival (OS) in first-line chemotherapy plus cetuximab for mCRC. We determined whether this concept was universally applicable to diverse standard chemotherapeutic regimens for mCRC. We reviewed mCRC patients who received the first-line systemic chemotherapy regimens FOLFOX, CapeOX or FOLFIRI (with biologics) at our department between June 2005 and March 2015. Data such as clinicopathological parameters, metastasized organs, chemotherapeutic regimens, the best response by RECIST v1.1, progression-free survival (PFS) and OS were retrospectively retrieved for patients who exhibited tumor shrinkage. DpR was calculated as the uni-dimensional maximum reduction rate of measurable tumors. We addressed the association between DpR and survival. Of the 156 patients receiving first-line chemotherapy regimens, tumor shrinkage was observed in 63 (41 of whom were men; median age 62 years). Complete remission was achieved in 6 patients, partial remission in 42 and stable disease in 15. The median DpR was 44.2% and was employed as the cutoff, in line with previous reports. DpR ≥45% (31 patients) was correlated with longer PFS (median 16.4 vs. 8.1 months for DpR <45%, p = 0.006) and OS (median 58.6 vs. 30.9 months for DpR <45%, p = 0.041). There was basically no difference in the subsequent chemotherapy between the DpR ≥45% and DpR <45% groups. DpR correlated with OS in various first-line systemic upfront chemotherapy regimens for mCRC. © 2015 S. Karger AG, Basel.

    From the 1950s to the 1970s, a number of in vitro systems that measured inhibition of glucose metabolism were used to predict the responsiveness of patients' tumors to chemotherapy. In vitro-in vivo correlations were excellent, with true positive predictions ranging from 68% to 96% and true negative predictions of 95% to 100%. The radiometric system is a new in vitro technique that measures the conversion of 14C-glucose to 14CO2. The system already has been utilized to screen prospective new antineoplastic agents for cytotoxicity. The present study was undertaken to determine if the radiometric system might be used to predict correctly the responsiveness of an individual patient's tumor to single-agent or combination-agent chemotherapy. Fifty-six tumor specimens were divided and tested for drug sensitivity in the radiometric system and a conventional human tumor clonning system. Overall, there was a significant correlation between in vitro and in vivo results for the conventional cloning system (P = 0.03). However, there was no significant relationship between in vitro and in vivo results for the radiometric system. The radiometric system consistently failed to predict the tumor's clinical sensitivity to single agents. A radiometric system is not useful in predicting the responsiveness of a patient's tumor to single agent chemotherapy and is not a replacement for the more biologically attractive human tumor cloning system.

    We report here a case of partial response to hepatic arterial infusion chemotherapy in a patient who developed serious hepatic failure due to unresectable colorectal cancer and hepatic metastasis and showed resistance to systemic chemotherapy with molecular targeted drugs, mFOLFOX6, and FOLFIRI. The patient was a 60-year-old woman who underwent sigmoidectomy for sigmoid colon cancer, lateral posterior hepatic segmentectomy for metastatic liver cancer, and postoperative radiation therapy for metastatic lung cancer. As first-line systemic chemotherapy, mFOLFOX6 (oxaliplatin, 5-fluorouracil, and leucovorin), bevacizumab + FOLFIRI (irinotecan, 5-fluorouracil, leucovorin), and anti-epidermal growth factor receptor antibody  + irinotecan were administered, in that order. However, recurrent hepatic metastasis was exacerbated, which induced serious hepatic failure manifested by general malaise, jaundice, abnormal hepatic function, difficulty in walking due to bilateral lower extremity edema, and decreased appetite. The patient was admitted in a serious condition. After hospitalization, the patient received hepatic arterial infusion chemotherapy with 5-fluorouracil and l-leucovorin. After two complete courses, the symptoms improved. The patient's performance status also improved, and she was discharged from the hospital. Four months after discharge, the patient had continued outpatient chemotherapy and maintained excellent performance status. Although HAIC is not presently considered an alternative to systemic chemotherapy, it is sometimes effective in patients who show resistance to molecular targeted drug therapy, FOLFOX, and FOLFIRI, and in whom hepatic metastasis is a key factor in determining prognosis and serious hepatic failure. Further studies should be performed in the future to verify these findings.

    Liver metastasis is associated with poor prognosis in gastric cancer. Surgical resection and systemic chemotherapy have been reported to be effective in gastric cancer with liver metastasis (GCLM). However, the best strategy for GCLM has not been established. From May 2009 to July 2014, a consecutive series of GCLM patients in Zhongshan Hospital of Fudan University were studied. Treatment strategies were evaluated with regard to different extents of metastases. A total of 163 patients were included. The overall survival was 10.1 months. Active treatment significantly prolongs the survival of GCLM patients. The overall survival time for patients with liver-limited metastases and extra-hepatic liver metastases was 11.6 mo and 8.7 mo, respectively (P = 0.012). The median survival time for liver-limited disease of H1, H2 and H3 was 14.2, 15.8, and 8.5 months, respectively (H3 vs H2, P = 0.001; H3 vs H1, P = 0.000; H1 vs H2, P = 0.900). Systemic chemotherapy was chosen as the main strategy for the 'extensive' patients with extra-hepatic metastases and H3 type liver-limited metastases. Patients' survival was benefited by multi-line chemotherapy. No differences were shown between systemic chemotherapy and curative resection or palliative resection in H1 and H2 liver-limited metastases (16.0 mo vs 12.0 mo, P = 0.711; 16.0 vs 18.8 months, P = 0.654). Systemic chemotherapy was the main treatment for gastric cancer patients with liver metastases. Curative resection could be considered for highly selected patients.

    Systemic and intrapleural chemotherapy for metastatic tumor pleurisy was carried out in cats with breast carcinoma. The animals (n=18) were divided into 2 groups. Cats of the systemic chemotherapy group received 3-6 courses of taxotere (30 mg/m(2); n=7) or 3 courses of taxotere (20 mg/m(2)) in combination with doxorubicin (20 mg/m(2)at 21-day intervals (n=5) during the adjuvant period of therapy for metastatic tumor pleurisy. Objective effect was attained in 10 (84.6%) cats: partial remission in 3 (25%) and complete remission in 7 (58.3%, p>0.05) cats. Metastatic pleurisy progressed in 2 (16.7%) cats. The median time to progression reached 1.79 months, median lifespan 2.8 months. The animals of intrapleural chemotherapy group (n=6) received 1-4 courses of cyclophosphamide (250 mg/m(2)) at 1-week interval during the adjuvant period without therapy for malignant pleurisy. Malignant pleurisy progressed in all cats. The median time to progression was equal to median lifespan (0.6 months). The therapy for malignant pleurisy in cats with breast cancer is regarded as the second-line chemotherapy with taxotere preferable as a monotherapy or in combination with doxorubicin.

    To analyze the genetic alterations identified in the RB1 gene in retinoblastoma patients who do not respond to systemic chemotherapy. A genetic analysis was performed on 115 patients with retinoblastoma, 40 of whom had received systemic chemotherapy, and 29 of them had bilateral disease. Descriptive and retrospective study. Non-responders were considered as patients who are finally enucleated. Patients with deletion type mutations are those with less preservation of the eyeball (Pearson Chi-square, P=.055). Patients with an impaired nonsense-frameshift type are more likely to preserve the eyeball. Of the 3 patients who had undergone bilateral enucleation, 2 of them had deletions and one missense alteration. Survival analysis (Kaplan-Meier curve) shows that patients with deletion type mutations are more resistance to chemotherapy, are suffering higher rates of enucleation, and for a shorter period of time (log rank [Mantel-Cox] with a significance level of P=.053), which are also associated with increased rate of being bilateral. Patients with a genotype show increased resistance to chemotherapy should be evaluated more closely and treated with various therapeutic weapons early. Patients that have deletions in the RB1 gene are at increased risk of chemoresistance. It is likely that other genetic alterations other than RB1 gene may be related to tumor aggressiveness and treatment resistance. Copyright © 2013 Sociedad Española de Oftalmología.

    The recent trend of treatment for retinoblastoma is to salvage the eye globes as well as achieving patients' survival. Intra-arterial chemotherapy (IAC) is one of the current standard treatment; however, it cannot exclude the risk of occult micrometastases in the central nervous system in advanced-stage retinoblastoma. Alternate fashion of intravenous chemotherapy (IVC) and IAC strategy was developed to increase the eye salvage rate and to reduce the metastatic risk. Between January 2012 and December 2014, 13 eyes of 12 patients with newly diagnosed retinoblastoma received alternate chemotherapy using IVC and IAC in Yonsei Cancer Center. Eye salvage rate was assessed by the eye preservation time, which was defined as the duration from the diagnosis to the time of enucleation. Total 13 eyes were classified according to the International Classification of Retinoblastoma (ICRB) as group B (n = 1, 7.7%), group C (n = 2, 15.4%), group D (n = 5, 38.5%), or group E (n = 5, 38.5%). IAC was performed, 3 to 5 times (median: 4 times) for each eye, total 54 times. Five to 15 courses (median: 8 courses) of systemic chemotherapy were performed in the patients. During the median follow-up period of 30.4 months, overall eye salvage rate was 63.9 ± 14.7%. All patients survived. The treatment was tolerable without significant complications. These results showed that primary alternate IVC-IAC was tolerable and effective for retinoblastoma.

    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.

    In recent years, cancer chemotherapy has been switching from hospital treatment to ambulant treatment. In such a situation, pharmacists are required to carry out their work unfailingly and smoothly in checking chemotherapy regimens, admixtures of drugs and providing information, for example. At Tokai University Hachioji Hospital, we have been trying to computerize a regimen-check, quantitative calculations for admixtures of anticancer drugs and the comment-input function of the pharmaceutical department so that our work will be more efficient and precise. The regimen-check system receives automatically, the patients' own data and the information of injection prescriptions and of the clinical laboratory from the Hospital Information System. Then pharmacists put the information to the regimen master file for recording in order to manage dosages, the accumulated dose and dose schedule. Also by registering the amount of dissolution of each anticancer drug beforehand, the quantitative calculation system makes it possible to automatically convert dosages on electronic medical charts to a liquid measure needed for the admixtures of drugs and to print the information on the prescription of injections. Additionally, the comment-input function makes it possible to print information on injections such as chemical information needed for regimen-checks and doctors' answers to questions about prescriptions. The pharmaceutical department system enables pharmacists to check regimens accurately and quickly to calculate the precise quantity for admixtures of drugs and to share information among pharmacists. The system has also contributed to the efficiency and medical safety of the ambulant cancer chemotherapy.

    Pharmacokinetic modeling has suggested, and clinical investigations have confirmed, that intracavitary drug administration can result in a much greater drug exposure for the cavity into which the agent is instilled compared to the plasma. Both the safety and the efficacy of several agents administered individually or in combination have now been demonstrated. Several malignancies, in particular ovarian carcinoma and malignant mesothelioma, which remain confined to body cavities for much of their natural history, might be most rationally treated by the intracavitary treatment approach. Early clinical trials have demonstrated significant activity of intracavitary chemotherapy in both of these malignancies. Optimal drugs and dosages as well as appropriate scheduling for the various tumors involving body cavities remain to be defined. Whether or not combination intracavitary chemotherapy will significantly improve survival of patients with malignant disease confined to body cavities must await carefully controlled clinical trials comparing this treatment approach to standard systemically administered chemotherapy. 144 references.

    Colorectal cancer liver metastasis (CRLM) is a refractory disease after failure of first-line or second-line chemotherapy. Bevacizumab is recommended as first-line therapy for advanced colorectal cancer, but is unproven in CRLM through the hepatic artery. We report favorable outcomes with targeted vessel regional chemotherapy (TVRC) for liver metastatic gastric cancer. TVRC with FOLFOX and bevacizumab perfusion through the hepatic artery was attempted for CRLM for efficacy and safety evaluation. In a single-institution retrospective observational study, 246 patients with CRLM after at least first-line or second-line failure of systemic chemotherapy received TVRC with FOLFOX (i.e. oxaliplatin, leucovorin, and 5-fluorouracil). Of 246 patients, 63 were enrolled into two groups: group 1 (n=30) received bevacizumab and TVRC following tumor progression during previous TVRC treatments; group 2 (n=33) received TVRC plus bevacizumab for CRLM on initiating TVRC. There were no significant differences in the median survival time (14.7 vs. 13.2 months, P=0.367), although the median time to progression was significant (3.3 vs. 5.5 months, P=0.026) between groups. No severe adverse events related to TVRC plus bevacizumab perfusion occurred. Target vessel regional chemotherapy with FOLFOX plus bevacizumab perfusion through the hepatic artery was effective and safe in CRLM. The optimal combination of TVRC and bevacizumab needs further confirmation in future phase II-III clinical trials.

    Advanced breast cancer patients have a higher risk of postoperative recurrence than early-stage breast cancer patients. Recurrence is believed to be caused by the increase in micrometases, which were not eradicated by preoperative or postoperative chemotherapy. Therefore, a new therapeutic strategy that can improve treatment efficacy is mandatory for advanced breast cancer. S-1 was shown to be effective and safe in Japanese metastatic breast cancer patients treated with previous chemotherapy, including anthracyclines. Thus, in this study, we evaluated S-1 as adjuvant chemotherapy in breast cancer patients after standard primary systemic chemotherapy. The treatment consisted of 18 courses (a 2-week administration and a 1-week withdrawal; one year) administered at 80-120 mg/body/day. In cases judged to require postoperative radiotherapy, it was concurrently initiated on Day 1 of the study. If the estrogen receptor and/or human epidermal growth factor receptor 2 were positive, endocrine therapy and/or trastuzumab were permitted, concurrently. Of the 45 patients enrolled between September 2007 and September 2009 from 3 institutions, 43 patients were eligible. Thirty-two of the 43 (74.4%) patients received concurrent radiotherapy. Twenty-two of the 43 (51.2%) patients completed the scheduled courses of chemotherapy. The most common reasons for withdrawal of treatment were subjective symptoms, such as nausea, anorexia, or general fatigue during the first 9 courses of treatment in 9/43 (20.9%) patients, recurrence in 7/43 (16.3%) patients, and adverse events in 5/43 (11.6%) patients. The cumulative percentage of administration for 365 days was 66.4% (95% confidence interval: 50.8-79.1%). Although grade 3 neutropenia (9.3%), leukopenia (4.7%), and diarrhea (4.7%) were observed, they were manageable. No grade 4 adverse effects were observed.

    We have previously reported that a burst of vascular endothelial growth factor (VEGF) signaling to tumor-associated endothelium induces a proviral state, during which systemically delivered oncolytic reovirus can replicate in endothelium, thereby inducing immune-mediated vascular collapse and significant antitumor therapy. Using chimeric receptors, we show here that induction of the proviral state proceeds through VEGFR2, but not VEGFR1, signaling in endothelial cells. In contrast, innate immune activation by reovirus-exposed endothelial cells was predominantly through VEGFR1. By screening conventional chemotherapies for their ability to induce similar effects in combination with reovirus both in vitro and in vivo, we observed that the proviral state could also be induced in endothelial cells exposed to VEGF during rebound from paclitaxel-mediated inhibition of VEGF signaling. We translated these in vitro findings in vivo by careful scheduling of paclitaxel chemotherapy with systemic virotherapy, neither of which alone had therapeutic effects against B16 tumors. Systemic availability of reovirus during endothelial cell recovery from paclitaxel treatment allowed for endothelial replication of the virus, immune-mediated therapy, and tumor cures. Therefore, careful scheduling of combination viro- and chemotherapies, which preclinical testing suggests are individually ineffective against tumor cells, can lead to rational new clinical protocols for systemic treatments with oncolytic viruses.

Therefore, careful scheduling of combination viro- and chemotherapies, which preclinical testing suggests are individually ineffective against tumor cells, can lead to rational new clinical protocols for systemic treatments with oncolytic viruses.

    Alopecia is a distressing side-effect of cancer treatment. Taxanes (TX), anthracyclines (ANR) and etoposide (ET) have been consistently associated with significant alopecia. We studied an effective scalp cooling system, the Penguin Cold Cap system, for the prevention of chemotherapy-induced alopecia in 70 patients receiving chemotherapy, including one of the following major alopecia-causing agents: Group A, TX-based regimes (without ANR); Group B, TX+ANR; Group C, ANR-based regimes (without TX); Group D, ET-based regimes. Protection from hair loss was achieved by maintaining scalp temperatures below 15 degrees C before, during and after chemotherapy by frequent changing of the caps. Assessment was carried out using a grading system from 0 to 4. Grades 0-2 were considered as satisfactory hair protection, whilst Grades 3-4 were considered failures. 57 patients were evaluable for assessment. An overall 81% protection was achieved. In groups C and D 11 of 12 patients (92%) had no alopecia, whilst 30 of 34 patients (88%) treated with taxanes had adequate hair protection. In Group B, 4 of 11 patients (36%) had adequate hair protection. The system was well tolerated and is a very effective method for protection from hair loss caused by TX, ANR and ET. Our results are comparable with and, in most cases, better than those reported in other studies using various alopecia preventive methods.

    Gastrointestinal cancers are asymptomatic in early tumor development, leading to high mortality rates. Peri- or postoperative chemotherapy is a common strategy used to prolong the life expectancy of patients with these diseases. Understanding the molecular mechanisms by which anticancer drugs exert their effect is crucial to the development of anticancer therapies, especially when drug resistance occurs and an alternative drug is needed. By integrating high-throughput techniques and computational modeling to explore biological systems at different levels, from gene expressions to networks, systems biology approaches have been successfully applied in various fields of cancer research. In this review, we highlight chemotherapy studies that reveal potential signatures using microarray analysis, next-generation sequencing (NGS), proteomic and metabolomic approaches for the treatment of gastrointestinal cancers.

    Chemotherapy-induced alopecia is frequent with most chemotherapy regimens; mechanisms, evolution and small prevention tools are described. Scalp cooling (helmets or continuous cooling systems) can avoid or diminish hair loss in selected chemotherapy regimens but tolerance can be fair and long harmlessness needs to be confirmed by prospective studies. Drug prevention is only in the first steps of research.

    Estimation of cytostatics influence used in breast cancer treatment on lysozyme activity in human tears depend on time of treatment. 8 women were treated at the base of chemotherapy schema: docetaxel with doxorubicin and 4 women treated with schema CMF: cyclophosphamide, methotrexate, 5-fluorouracil. Lysozyme activity in tears was assessed by measurement of diameter zone of Micrococcus lysodeicticus growth inhibition. It was revealed that both chemotherapy schema caused statistically significant reduction of diameter zone of M. lysodeicticus growth inhibition, after first and second course of chemotherapy treatment. After second chemotherapy course CMF schema induced loss of lysozyme activity in patient's tears (zero mm of M. lysodeicticus diameter zone growth inhibition). Systemic chemotherapy administered in breast cancer induce reduction of lysozyme activity in tears, that may cause higher morbidity of ocular surface infections caused by Gram-positive bacteria.

    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.

    Using circulating granulocyte-monocyte precursor colony-forming units in culture (CFUc) numbers as a probe along with standard blood count (CBC), the authors have quantitatively examined the hematopoietic toxicity of conventionally fractionated radiation therapy (RT) when combined with concurrent systemic chemotherapy or when used alone. Among 20 patients with limited stage small cell lung cancer receiving systemic chemotherapy with cyclophosphamide, CCNU, and methotrexate, the addition of involved field chest RT resulted in increased hematopoietic toxicity as judged by increased need for platelet transfusion (P less than 0.05) and decreased frequency of measurable CFUc (P less than 0.04). Among 22 patients receiving regional radiotherapy alone consistent hematopoietic toxicity was also observed. This toxicity, although generally of only mild to moderate clinical significance, was detected earlier and to a greater degree in patients who required radiation to larger treatment volumes, who had significant amounts of bone marrow in the port, and who had a high percentage of cardiac output flowing through the port. These data suggest that the hematopoietic toxicity of regional radiotherapy may be additive to that of concurrent systemic chemotherapy and may occur more promptly and to a greater degree when treatment volumes are larger or incorporate increased amounts of marrow volume or cardiac output.

  8. Neurological complications of chemotherapy to the central nervous system.

    PubMed

    Newton, Herbert B

    2012-01-01

    One of the most common complications of chemotherapeutic drugs is toxicity to the central nervous system (CNS). This toxicity can manifest in many ways, including encephalopathy syndromes and confusional states, seizure activity, headache, cerebrovascular complications and stroke, visual loss, cerebellar dysfunction, and spinal cord damage with myelopathy. For many drugs, the toxicity is related to route of administration and cumulative dose, and can vary from brief, transient episodes to more severe, chronic sequelae. However, the neurotoxicity can be idiosyncratic and unpredictable in some cases. Among the antimetabolite drugs, methotrexate, 5-fluorouracil, and cytosine arabinoside are most likely to cause CNS toxicity. Of the alkylating agent chemotherapeutic drugs, the nitrosoureas (e.g., BCNU) and cisplatin most frequently cause toxicity to the CNS, especially when given via the intra-arterial route. Ifosfamide is also likely to cause neurotoxicity at high intravenous doses. Other alkylating agents, such as busulfan, cyclophosphamide, procarbazine, and temozolomide, are better tolerated by the CNS at moderate doses. The retinoid drugs are known to cause severe headaches at high doses. l-Asparaginase can induce an encephalopathy syndrome, as well as cerebrovascular complications such as stroke.

    Primary central nervous system lymphoma is a rare and distinct subtype of non-Hodgkin's lymphoma that is sensitive to radiation and chemotherapy. Decisions regarding the initial therapeutic approach are influenced by age and risk of therapy-related neurotoxicity. Despite several albeit small phase II studies, and the acknowledged need for larger prospective trials, there is supporting evidence to consider auto-SCT following induction chemotherapy in patients with good performance status. The international extranodal lymphoma study group is conducting a randomized phase II study comparing consolidative radiation therapy to high-dose therapy. Novel therapeutic options including early aggressive approach with upfront auto-SCT and strategies to prevent relapse following transplantation is an area of focus. PMID:22002486

    In patients with breast cancer (BC) undergoing systemic chemotherapy, cancer-related fatigue (CRF) is a common problem that can negatively impact quality of life. Guarana (Paullinia cupana) is a plant native to the Amazon basin that has been used as a stimulant since pre-Columbian times. The purpose of this study was to evaluate the effectiveness of guarana extract on fatigue, sleep quality, anxiety, depression symptoms, and menopause in a group of BC chemotherapy patients. Patients with progressive fatigue after their first cycle of chemotherapy were randomized to receive either guarana 50 mg by mouth twice daily (32 patients) or placebo (43 patients) for 21 days. After a 7-day washout period, patients were crossed over to the opposite experimental arm. All patients were evaluated on days 1, 21, and 49. The primary endpoint was the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire score, and secondary endpoints were the results of the Functional Assessment of Chronic Illness Therapy-Endocrine Symptoms (FACT-ES), Brief Fatigue Inventory (BFI), Pittsburg Sleep Quality Index, Chalder Fatigue Scale, and Hospital Anxiety and Depression Scale. Guarana significantly improved the FACIT-F, FACT-ES, and BFI global scores compared to placebo on days 21 and 49 (p < 0.01). The Chalder Scale improved significantly on day 21 (p < 0.01) but not on day 49 (p = 0.27). Guarana did not produce any Common Terminology Criteria for Adverse Events grades 2, 3, or 4 toxicities and did not worsen sleep quality or cause anxiety or depression. Guarana is an effective, inexpensive, and nontoxic alternative for the short-term treatment of fatigue in BC patients receiving systemic chemotherapy. Further studies are needed to confirm these results and to evaluate their generalizability to chronic CRF and to other types of cancer.

    ABSTRACT Introduction: Advanced non-small cell lung cancer (NSCLC) is traditionally treated with platinum-based chemotherapy and radiotherapy. Since immunotherapy holds promise for treating advanced NSCLC, we assessed the systemic effects of the traditional therapies for NSCLC on immune cell composition and function. Methods: 84 pulmonary adenocarcinoma patients, treated either with chemotherapy or radiotherapy, were studied. A prospective study of 23 patients was conducted in which the myeloid and lymphoid cell compartments of peripheral blood were analyzed. Changes in cell populations were validated in a retrospective cohort of 61 adenocarcinoma patients using automated differential counts collected throughout therapy. Furthermore, the functional capacity of circulating T cells and antigen-presenting cells (APC) was studied. Blood samples of healthy individuals were used as controls. Results: In comparison to healthy controls, untreated adenocarcinoma patients display an elevated frequency of myeloid cells coinciding with relative lower frequencies of lymphocytes and dendritic cells. Standard chemotherapy had no overt effects on myeloid and lymphoid cell composition nor on T-cell and APC-function. In contrast, patients treated with radiotherapy displayed a decrease in lymphoid cells and a relative increase in monocytes/macrophages. Importantly, these changes were associated with a reduced APC function and an impaired response of T cells to recall antigens. Conclusions: Platinum-based standard of care chemotherapy for NSCLC has no profound negative effect on the immune cell composition and function. The negative effect of prolonged low-dose radiotherapy on the immune system warrants future studies on the optimal dose and fraction of radiotherapy when combined with immunotherapy. PMID:28123900

    To report the efficacy of neoadjuvant systemic chemotherapy in the management of eyelid sebaceous gland carcinoma (SGC). Retrospective study of 10 patients that received neoadjuvant systemic chemotherapy (Cisplatin/Carboplatin and 5-Fluorouracil) for eyelid SGC. The mean age at presentation of eyelid SGC was 58 years (median, 55 years; range, 45 to 72 years). There were 6 females and 4 males. The mean tumor basal diameter was 36 mm (median, 31 mm, range, 20 to 65 mm), with orbital tumor extension in 9 cases. On the basis of TNM Classification, the tumors were classified as T3 (n = 10), N1 (n = 6), and M1 (n = 2). The mean number of cycles of neoadjuvant systemic chemotherapy per patient was 3 (median, 3; range, 3 to 4). The mean percentage reduction of tumor basal diameter after neoadjuvant chemotherapy was 74% (median, 80%; range, 30% to 100%). None of them had any major systemic side-effects of neoadjuvant chemotherapy. Postchemotherapy, surgical treatment for residual tumor was performed in 7 cases. Five cases underwent excision biopsy and 2 cases with residual orbital component underwent eyelid-sparing orbital exenteration. No tumor recurrence was noted in any of the 7 cases at a mean follow-up period of 18 months (median, 14 months; range, 3 to 63 months). One patient died due to systemic metastasis. Neoadjuvant systemic chemotherapy is effective and safe in the management of eyelid sebaceous gland carcinoma.

    Trastuzumab is an immunotargeting therapeutic against breast tumors with amplification of the human epithelial growth factor receptor 2 (HER2). HER2 patients naturally exhibit disruption in the pro-oxidant inflammatory profiling; however, the impact of trastuzumab-based chemotherapy in modulating this process is still unknown. Here we determined the systemic pro-inflammatory profile of women diagnosed with HER2-amplified tumors, undergoing trastuzumab-based chemotherapy (TZ), and compared the results with that of healthy controls (CTR) and untreated patients with HER2-amplified breast cancer (CA). The plasmatic inflammatory profile was assessed by evaluating pro-oxidant parameters such as lipid peroxidation, total antioxidant capacity (TRAP), levels of advanced oxidation protein products (AOPPs), nitric oxide (NO), C-reactive protein (CRP), and total thiol content. Markers of cardiac damage were also assessed. Our findings showed increased NO levels in TZ than that in either CA or CTR groups. Furthermore, TZ augmented TRAP and reduced total thiol than that of the CA group. Our data also revealed that AOPP levels were significantly higher in the TZ than the CA group. AOPP and the MB fraction of creatine-kinase (CKMB) levels were positively correlated in TZ patients. These findings suggest that trastuzumab-associated chemotherapy can modulate the pro-inflammatory markers of HER2-positive breast cancer patients to the levels found in healthy controls.

    Liver metastases from breast cancer are generally treated with systemic therapy such as chemotherapy or hormonotherapy. However, local treatment options such as resection, radiofrequency ablation (RFA), and radiotherapy can also be considered to treat oligometastases. We report the case of a 45-year-old female treated with stereotactic body radiotherapy (SBRT) after chemotherapy against a solitary liver metastasis from primary breast cancer. A liver metastasis with diameter of 35 mm developed 3.5 years after surgery for primary breast cancer in 2004. Fourteen courses of triweekly docetaxel treatments considerably decreased the metastatic lesion, but there still remained a tiny lesion radiographically. Chemotherapy was stopped because of the side-effects of docetaxel, and then SBRT was selected for additional treatment, aiming at complete cure of metastasis. X-ray irradiation (52.8 Gy/4 fractions) was applied to the remaining metastatic lesion, and magnetic resonance imaging (MRI) showed no evidence of residual tumor 4 months after irradiation. Neither regrowth nor recurrences have been found until now, 24 months after SBRT. SBRT for oligometastases of breast cancer may be one of the possible curative-intent options, being less invasive than surgical resection or RFA.

    To describe the efficacy of intravitreal chemotherapy (IViC) preceded by intra-arterial chemotherapy (IAC) for the treatment of advanced stage retinoblastoma. This non-comparative interventional case series retrospectively reviewed the medical records of six patients who presented within months of each other with unilateral retinoblastoma, Reese-Ellsworth stage Vb/D of ABC classification in the affected eye. After clinical and ophthalmoscopic evaluation, they underwent MRI to exclude local and CNS dissemination. The IAC was given to treat retinal masses and intravitreal injections to treat vitreous seeding. Patients had received two cycles (six infusions) of IAC, and from six up to ten melphalan injections into the vitreous, with an interval of 7-10 days between them. From one to four intravitreal injections were performed for partial remission or consolidation. No permanent complications of procedures have been reported. All patients underwent to bimonthly MRI examination, during treatment and every 3 months for 1 year after last injection, to exclude orbital dissemination. Successful control (100 %) of tumor masses and vitreous seeds was achieved in all cases at 12 months follow-up. Complications were posterior lens opacity, acute ischemic papillitis, partial CVR thrombosis, hypotonia (case 1), partial vitreous hemorrhage (case 4). No complications appeared in cases 2, 3, 5, and 6. No intraocular or orbital tumor recurrence or retinoblastoma metastases (follow-up range, 12-33 months) were observed. Sequential IAC and intravitreal melphalan for advanced retinoblastoma allowed to provide retinal and vitreous seed control.

    There are few reports investigating the potential benefits of preoperative systemic chemotherapy for patients with node-positive upper tract urothelial carcinoma. The purpose of this study was to examine the impact of preoperative systemic chemotherapy on the clinical outcomes of patients with node-positive upper tract urothelial carcinoma treated by radical nephroureterectomy. Data were collected on 195 consecutive patients with upper tract urothelial carcinoma treated by radical nephroureterectomy between 1995 and 2010 at a single institute. Of these, 29 patients with node-positive disease but no visceral metastasis were retrospectively evaluated. In patients who underwent preoperative systemic chemotherapy, tumor response, post-therapy pathological downstaging to either residual disease at radical nephroureterectomy or no residual lymph node metastasis (pN0) and toxicity were the endpoints of interest. Overall survival was compared between two groups: those with and without preoperative chemotherapy. All patients underwent regional lymphadenectomy. Overall, 15 patients (52%) underwent preoperative systemic chemotherapy. Pathological downstaging was achieved in 47%, including pN0, but there was no pathological complete response. Eighty-six percent of the patients with pathological downstaging had no evidence of recurrence. The median overall survivals were 38 and 9 months for patients with and without preoperative systemic chemotherapy, respectively (hazard ratio: 0.26, P = 0.015, log-rank test). There was no significant difference in operative morbidity between the two groups, and no operations were delayed because of preoperative chemotherapy. The survival of patients who undergo preoperative systemic chemotherapy following radical nephroureterectomy seems to be superior to that of those undergoing radical nephroureterectomy alone. However, to confirm this, prospective randomized studies are needed.

    To evaluate long-term progression-free survival and overall survival, quality of life, and cognitive function in primary central nervous system lymphoma after systemic and intraventricular chemotherapy without radiotherapy. A long-term follow-up was conducted on surviving primary central nervous system lymphoma patients having been enrolled in a pilot/phase II trial between September 1995 and December 2001. Initially, 65 patients (median age, 62 years) had been treated with systemic and intraventricular chemotherapy without radiotherapy. All living patients were contacted, and a neurological examination, comprehensive neuropsychological testing, quality-of-life assessment, and imaging were performed. Twenty-one of all 65 patients (32 %) and 17 of 30 patients 60 years or younger (57%), respectively, were still alive at median follow-up of 100 months (range, 77-149 months). Nineteen of 21 patients completed all investigations; 1 was lost to follow-up. In three patients, an exclusively extraneural relapse of a high-grade non-Hodgkin's lymphoma was diagnosed after 9, 31, and 40 months, respectively. All of them experienced complete remission to high dose. Neither late neurotoxicity nor compromise of quality of life was found in any of the patients examined. Primary polychemotherapy based on high-dose methotrexate (MTX) and cytarabine (Ara-C) is highly efficient in treatment of primary central nervous system lymphoma. About half of patients 60 years or younger can obviously be cured with this regimen without long-term neurotoxic sequelae or quality-of-life compromise.

    Plasma D-dimer levels have been known to be associated with tumor progression; we, therefore, investigated whether the D-dimer levels during preoperative systemic chemotherapy can be prognostic indicators in patients with high-grade musculoskeletal sarcoma. We investigated 28 cases of high-grade sarcomas, and evaluated the utility of D-dimer levels for preoperative evaluation of the effects of systemic chemotherapy. Among the candidate parameters determined based on D-dimer levels at several time-points of neoadjuvant chemotherapy and several oncological outcomes, the plasma D-dimer level completion of the second course of chemotherapy and the ratio of plasma D-dimer levels at completion of preoperative chemotherapy to the level of plasma D-dimer on referral, could significantly predict patient prognosis (p=0.049 and p=0.02, respectively). D-dimer level changes could be a helpful marker for preoperative evaluation of the effect of systemic chemotherapy in terms of prognosis prediction in high-grade musculoskeletal sarcoma patients.

    Radionuclide techniques have been used to estimate the systemic shunt and to quantitate blood flow to the tumor and a reference normal tissue in nine patients undergoing intraarterial chemotherapy for head and neck cancer. The systemic shunt was calculated as the percentage of pulmonary trapping of intraarterially injected /sup 99m/Tc-labeled macroaggregated albumin. The mean systemic shunt in the 12 separate arteries studied was 23 +/- 13% (SE) (range 8-43%). Quantitative blood flow was determined from the slope of the washout curve of intraarterially injected /sup 133/Xe. The mean tumor blood flow was 13.6 +/- 6.7 ml/100 g/min, while the mean blood flow to the scalp was 4.2 +/- 2.1 ml/100 g/min providing a mean tumor/normal tissue ratio of 3.9 +/- 2.7. An estimate of blood flow distribution was obtained by calculating the ratio of counts/pixel in the tumor mass versus the remainder of the head as determined by single photon emission computed tomography following an intraarterial injection of /sup 99m/Tc-labeled macroaggregated albumin. The mean ratio of tumor to normal tissue perfusion by this technique was 5.6 +/- 3.7. These techniques have allowed noninvasive determination of the blood flow parameters associated with intraarterial chemotherapy. At least part of the therapeutic advantage of regional chemotherapy in patients with head and neck cancer is due to a tumor/normal tissue blood flow ratio that favors drug delivery to the tumor contained within the infused volume.

    Targeted therapy for osteosarcoma includes organ, cell and molecular biological targeting; of these, organ targeting is the most mature. Bone-targeted drug delivery systems are used to concentrate chemotherapeutic drugs in bone tissues, thus potentially resolving the problem of reaching the desired foci and minimizing the toxicity and adverse effects of neoadjuvant chemotherapy. Some progress has been made in bone-targeted drug delivery systems for treatment of osteosarcoma; however, most are still at an experimental stage and there is a long transitional period to clinical application. Therefore, determining how to combine new, polymolecular and multi-pathway targets is an important research aspect of designing new bone-targeted drug delivery systems in future studies. The purpose of this article was to review the status of research on targeted therapy for osteosarcoma and to summarize the progress made thus far in developing bone-targeted drug delivery systems for neoadjuvant chemotherapy for osteosarcoma with the aim of providing new ideas for highly effective therapeutic protocols with low toxicity for patients with osteosarcoma. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

    A port catheter system for hepatic artery infusion chemotherapy was implanted percutaneously via the left subclavian artery in 41 patients for treatment of unresectable liver metastases. The catheter tip was inserted into the gastroduodenal artery (GDA), the end hole was occluded with a guidewire fragment, and a side-hole for infusion was positioned at the bifurcation of the proper hepatic artery and the GDA. The GDA was embolized with steel coils around the infusion catheter tip via a transfemoral catheter. This procedure is designed to reduce the incidence of hepatic artery occlusion and infusion catheter dislocation.

    Primary germ cell neoplasms of the central nervous system (CNS) are rare tumors which generally respond to radiotherapy. Experience is limited in managing the refractory patient. We report a patient whose suprasellar dysgerminoma responded completely to 5,000 rad. Seven years later, disease recurrence was refractory to an additional 4,000 rad. Theorizing that the ''blood-brain barrier'' was no longer intact after extensive radiotherapy and tumor involvement of the ventricular system, the patient was treated with systemic bleomycin, cisplatin, and vinblastine. Pharmacokinetic studies revealed that the bleomycin and cisplatin entered the cerebrospinal fluid. Serial CT scans and CSF levels of beta-HCG confirmed the clinical impression of a partial remission. Subsequent tumor progression was refractory to therapy with intraventricular bleomycin. It is concluded that systemic chemotherapy may be beneficial in certain cases of CNS germ cell neoplasms.

    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.

    Malignant small bowel obstruction (MSBO) that does not resolve with conservative measures frequently leaves few treatment options other than palliative care. This single-institution retrospective study assesses the outcomes of a more aggressive approach-concurrent systemic chemotherapy and total parenteral nutrition (TPN)-in the treatment of MSBO. The MD Anderson pharmacy database was queried to identify patients who received concurrent systemic chemotherapy and TPN between 2005 and 2013. Only patients with MSBO secondary to peritoneal carcinomatosis requiring TPN for ≥8 days were included. Survival and multivariate analyses were performed using the Kaplan-Meier method and Cox proportional hazard models. The study included 82 patients. MSBO resolution was observed in 10 patients. Radiographic assessments showed a response to chemotherapy in 19 patients; 6 of these patients experienced MSBO resolution. Patients spent an average of 38% of their remaining lives hospitalized, and 28% of patients required admission to the intensive care unit. In multivariate modeling, radiographic response to chemotherapy correlated with MSBO resolution (odds ratio [OR] 6.81; 95% confidence interval [CI], 1.68-27.85, P = 0.007). Median overall survival (OS) was 3.1 months, and the 1-year OS rate was 12.6%. Radiographic response to chemotherapy (HR 0.30; 95% CI, 0.16-0.56, P < 0.001), and initiation of new chemotherapy during TPN (HR 0.55; 95% CI, 0.33-0.94, P = 0.026) independently predicted for longer OS. Concurrent treatment with systemic chemotherapy and TPN for persistent MSBO results in low efficacy and a high morbidity and mortality, and thus should not represent a standard approach. © 2015 The Authors.

    The rational application of chemotherapy in tumors of the central nervous system is discussed in particular the use of the new derivatives of nitrosourea: BCNU (1-3 bis-(2-cloroetil) 1-nitrosourea) and CCNU (cloroetil-cicloesil-nitrosourea). The results of therapy with antimetabolites, alkylating agents, antibiotics, and plant alcaloids, are reported as well as those obtained with radio - sensitizing substances (containing B10 or BUdR, IUdR, FUdR). The results obtained in the United States and in Japan with BCNU and CCNU are considered as well as the personal data of 43 cases treated with BCNU and 10 cases treated with CCNU (including intracranial glial tumors, spinal glial tumors and metastatic tumors of the central nervous system).

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.

    Although small cell lung cancer (SCLC) is very chemosensitive, cerebral metastases are treated with radiotherapy in the belief that they are protected from chemotherapy by the blood-brain barrier (BBB). The validity of this assumption has not been tested in clinical practice. In a randomised trial of treatment in 610 patients with SCLC, 19 patients who had symptomatic cerebral metastases at presentation were treated initially with chemotherapy, and cranial irradiation withheld. Chemotherapy was cyclophosphamide 1 g m-2 i.v. day 1, vincristine 2 mg i.v. day 1 and etoposide 100 mg tds p.o. days 1-3, repeated every 21 days, with response assessed objectively by computerised tomography (CT) or radionuclide brain scan, and by clinical examination. A post-chemotherapy scan was obtained in 14 patients, eight of whom achieved a partial remission and one a complete remission of the cerebral metastases. The radiologically proven responses were sustained and accompanied by rapid neurological improvement. Of the remaining five patients who were assessed by clinical examination alone, one had improved neurological function after chemotherapy. The response rate for SCLC cerebral metastases treated with chemotherapy was therefore 10/19 (53%). Chemotherapy has the advantage over cranial irradiation of simultaneously treating both cerebral metastases and extracranial disease. The place of chemotherapy in the management of cerebral metastases in this and other chemosensitive tumours should be reconsidered since these findings indicate that the BBB does not prevent response to chemotherapy.

  10. Chemotherapy-induced mucositis: the role of mucin secretion and regulation, and the enteric nervous system.

    PubMed

    Thorpe, Daniel; Stringer, Andrea; Butler, Ross

    2013-09-01

    Alimentary mucositis is a severe, dose-limiting, toxic side effect of cytotoxic chemotherapy and radiotherapy. Patients with mucositis often have reductions or breaks imposed on cytotoxic therapy, which may lead to reduced survival. Furthermore, there is an increased risk of infection and hospitalization, compounding the cost of treatment. There are currently limited therapeutic options for mucositis, and no effective prevention available. Mucin expression and secretion have been shown to be associated with mucositis. Furthermore, mucins exhibit protective effects on the alimentary tract through reducing mechanical and chemical stress, preventing bacterial overgrowth and penetration, and digestion of the mucosa. Additionally, a number of studies have implicated some key neurotransmitters in both mucositis and mucin secretion, suggesting that the enteric nervous system may also play a key role in the development of mucositis.

  11. Chemotherapy-Related Neurotoxicity.

    Taillibert, Sophie; Le Rhun, Emilie; Chamberlain, Marc C

    2016-09-01

    Chemotherapy may have detrimental effects on either the central or peripheral nervous system. Central nervous system neurotoxicity resulting from chemotherapy manifests as a wide range of clinical syndromes including acute, subacute, and chronic encephalopathies, posterior reversible encephalopathy, acute cerebellar dysfunction, chronic cognitive impairment, myelopathy, meningitis, and neurovascular syndromes. These clinical entities vary by causative agent, degree of severity, evolution, and timing of occurrence. In the peripheral nervous system, chemotherapy-induced peripheral neuropathy (CIPN) and myopathy are the two main complications of chemotherapy. CIPN is the most common complication, and the majority manifest as a dose-dependent length-dependent sensory axonopathy. In severe cases of CIPN, the dose of chemotherapy is reduced, the administration delayed, or the treatment discontinued. Few treatments are available for CIPN and based on meta-analysis, duloxetine is the preferred symptomatic treatment. Myopathy due to corticosteroid use is the most frequent cause of muscle disorders in patients with cancer.

    The last 3 decades have witnessed limited therapeutic advances in small cell lung cancer (SCLC) management. This study evaluated real-world trends in the use of systemic therapies and the impact on patient outcomes in the United States. The Surveillance, Epidemiology, and End Results-Medicare database was used to find patients diagnosed with SCLC between 1985 and 2005. The 1985-1990 period served as the baseline for a temporal analysis conducted at 5-year intervals (1985-1990, 1991-1995, 1996-2000, and 2001-2005). Cox proportional models were used to estimate the effect of chemotherapy on survival. Results were validated with a propensity-matched analysis. There were 47,351 eligible patients: 52% were male; the median age was 71 years; and 87% were white, 7% were black, and 1.4% were Asian. The proportion of patients treated with chemotherapy was low but increased over time (38%, 55%, 50%, and 53%; P < .001). Race, diagnosis period, age, stage, and location of residence significantly predicted chemotherapy use. Females (51%), Asians (53%), and rural residents (60%) were more likely to receive chemotherapy. The median overall survival with and without chemotherapy was 9.6 and 3.6 months, respectively. Linear trend analyses showed a modest reduction in the impact of chemotherapy on survival for patients treated with chemotherapy versus untreated patients (hazard ratios [HRs], 0.59, 0.61, 0.64, and 0.62; P < .001) but an overall trend of improved survival for treated (HRs, 1.0, 1.03, 1.00, and 0.96; P = .005) and untreated patients (HRs, 1.0, 0.99, 0.94, and 0.92; P < .001). There was no survival difference between patients treated with carboplatin and patients treated with cisplatin (HR, 0.99; confidence interval [CI], 0.81-1.19; P = .875). Additional therapy beyond platinum-based chemotherapy was associated with a survival benefit (HR, 0.78; CI, 0.75-0.81; P < .001).

    Chemotherapy is the mainstay of treatment of advanced non-small cell lung cancer (NSCLC) without molecular drivers. Despite a low penetration of central nervous system (CNS), chemotherapy drugs demonstrated encouraging activity against CNS metastases from NSCLC. Based on the available data, chemotherapy should be considered as an important part of the multidisciplinary treatment of CNS metastases. Particularly, platinum-based regimens represent the most active combinations and pemetrexed is associated with a meaningful clinical benefit for patients with non-squamous histology. How to integrate chemotherapy and radiotherapy for newly diagnosed brain metastases (BMs) is still debated. Although flawed by some limitations, the available evidence suggests a role for upfront chemotherapy for the treatment of NSCLC patients with synchronous, asymptomatic BMs, thus allowing a delay of radiotherapy. Despite the introduction of modern and more effective chemotherapy, however, the prognosis of NSCLC patients with CNS metastases remains poor, especially for those with progressive BMs or leptomeningeal carcinomatosis (LC).

    Purpose. The efficacy of chemoembolization of primary and metastatic gestational trophoblastic neoplasms was studied. Methods. Six female patients, 19-33 years old, with high-risk trophoblastic disease were subjected to one to five chemoembolizations in 3-week intervals. Three of the patients had metastases to the liver, 2 had local tumor extension to the pelvic wall, and all 5 had failed initial systemic chemotherapy. The sixth patient was treated for a trophoblastic remnant following surgical expression of a tubal pregnancy. For follow-up, beta hCG levels in urine and serum and dynamic or angiocomputed tomograms were obtained in biweekly to 6-month intervals. Results. Two of 3 patients with liver metastases are alive and free of disease 6 and 7 years after initial chemoembolization. The third is alive at 3 years but with evidence of recurrent disease. Two patients treated for locally invasive trophoblastic disease died 3 months and 4 years, respectively, after initial chemoembolization. One had a 21/2-year remission. The patient treated for a trophoblastic remnant in the tube is alive and free of disease at 6-year follow-up. Hematologic toxicity occurred in only one. Conclusion. Selective chemoembolization in our small series of patients with high-risk trophoblastic disease was equally effective as results reported for multi-drug systemic chemotherapy but had markedly lower renal, liver, and hematologic toxicity.

    The development of tumor-targeting drug delivery systems, able to selectively transport cytotoxic agents into the tumor site by exploiting subtle morphological and physiological differences between healthy and malignant cells, currently stands as one of the most attractive anticancer strategies used to overcome the selectivity problems of conventional chemotherapy. Owing to frequent overexpression of folate receptors (FRs) on the surface of malignant cells, conjugation of cytotoxic agents to folic acid (FA) via suitable linkers have demonstrated to enhance selective drug delivery to the tumor site. Herein, the chemical synthesis and biological evaluation of two novel folate-conjugates bearing the anticancer agent chlorambucil (CLB) tethered to either an aminoether (4,7,10-trioxa-1,13-tridecanediamine) or a pseudo-β-dipeptide (β-Ala-ED-β-Ala) linker is reported. The two drug delivery systems have been prepared in high overall yields (54% and 34%) through straightforward and versatile synthetic routes. Evaluation of cell specificity was examined using three leukemic cell lines, undifferentiated U937 (not overexpressing FRs, FR(-)), TPA-differentiated U937 (overexpressing FRs, FR(+)), and TK6 (FR(+)) cells. Both conjugates exhibited high specificity only to FR(+) cells (particularly TK6), demonstrating comparable antitumor activity to CLB in its free form. These data confirm the reliability of folate-based drug delivery systems for targeted antitumor therapy; likewise, they lay the foundations for the development of other folate-conjugates with antitumor potential.

    This study was designed to determine response rate, survival and toxicity associated with combination chemotherapy delivered intra-arterially to liver in patients with hepatic metastases of colorectal origin refractory to standard systemic treatment. A total of 28 patients who failed prior systemic treatment with fluoropyrimidines received a median of 5 cycles of intra-arterial treatment consisting of 5-fluorouracil 700 mg/m2/d, leucovorin 120 mg/m2/d, and cisplatin 20 mg/m2/d for 5 consecutive days. Cycles were repeated at intervals of 5–6 weeks. A major response was achieved in 48% of patients: complete response in 8% and partial response in 40%. The median duration of response was 11.5 months. Median survival was 12 months at a median follow up of 12 months. On multivariate analysis, the only variables with a significant impact on survival were response to treatment and performance status. Toxicity was moderate: grades III–IV neutropenia occurred in 29% of patients. Most of the patients complained of fatigue lasting for a few days following each cycle. There were no cases of hepatobiliary toxicity. These findings indicate that regional intra-arterial treatment should be considered in selected patients with predominantly liver disease following failure of standard treatment. © 2001 Cancer Research Campaign http://www.bjcancer.com PMID:11506487

    Five hundred three patients with advanced malignant melanoma were exposed to a number of clinical investigative chemotherapeutic regimens between 1971 and 1984 in an effort to assess the clinical activity of these regimens in this disease. Of the 503 patients participating in the studies, ten patients experienced a complete response. However, only three of these patients survived more than 5 years. Of this group of 503 patients, seven additional patients who did not experience a complete response survived more than five years. Of the ten patients surviving more than 5 years, two had immediate progression after institution of investigative regimens, whereas five remained stable for brief periods of time before progressive metastatic disease. Three patients experienced a complete response. It appeared that systemic therapeutic interventions in these trials were conspicuously ineffective for this large group of patients. A few long-term survivors attest to the capricious nature of this neoplasm and its association with likely spontaneous regressions. Although these long-term survivors did survive after institution of systemic chemotherapy, it is likely that this survival was related temporally, but perhaps not causally, to the institution of treatment.

    Adverse drug-drug interactions (DDI) are a major cause of morbidity and mortality in susceptible populations. Cancer patients are a population at high risk for DDI especially because they commonly receive several drugs concomitantly. The knowledge about the most common interactions between drugs used in oncology inpatients is essential to reduce drug-related problems and increase the safety and efficacy of the therapy. To assess the frequency of potential DDI throughout the hospital stay of cancer patients undergoing systemic chemotherapy, describe their epidemiology, and identify risk factors for major DDI.

All patients had at least one potential DDI (median, 7.0/patient; 25th-75th percentile, 3.5-12.0), and 46 % of the patients had at least one DDI classified as major, i.e. that it may result in death, hospitalization, permanent injury, or therapeutic failure. Only 13.7 % of all interactions involved antineoplastic agents, identified in 62.8 % of patients. Most interactions were of moderate severity, 6.4 % were major, and 8.5 % had a recommendation for therapy modification. Multivariate analysis revealed mean number of drugs prescribed [relative risk (RR) for each additional drug: 1.12; 95 % confidence interval (CI) 1.07-1.17; P < 0.01] and age ≥60 years (RR 1.48; 95 % CI 1.03-2.14; P < 0.01) as independent risk factors for major DDI. Potential DDI were highly frequent in this cohort. Older age and number of drugs prescribed were more likely to lead to major interactions.

    Chemotherapy improves survival in patients with stage IV colorectal cancer (CRC). Although in a clinical trial setting, strict eligibility criteria are used for chemotherapy, little is known about the use of chemotherapy in the general population. The study aims to assess clinicopathological variables that correlate with the use of chemotherapy in patients with stage IV CRC. A retrospective cohort study involving patients with stage IV CRC, diagnosed between 1992 and 2005, in the province of Saskatchewan was carried out. A logistic regression analysis was performed to assess the correlation of various clinicopathological factors with the use of chemotherapy. A total of 1,237 eligible patients were identified. Their median age was 70 years (range: 22-98) and the male:female ratio was 1.3:1. 23.8% had an ECOG performance status (PS) of ≥2 and 61.8% of the patients had a comorbid illness. 46.8% of the patients received chemotherapy. The multivariate logistic regression analysis revealed that an age of <65 years [odds ratio (OR) 3.82, 95% CI: 2.59-5.63], metastasectomy (OR 3.60, 95% CI: 1.82-7.10), normal albumin (OR 3.26, 95% CI: 2.44-4.36), no comorbid illness (OR 2.87, 95% CI: 1.34-6.16), ECOG PS of <2 (OR 2.72, 95% CI: 1.94-3.82), normal blood urea nitrogen (OR 2.24, 95% CI: 1.40-3.59), palliative radiation (OR 2.03, 95% CI: 1.38-2.99), primary tumor resection (OR 2.00, 95% CI: 1.47-2.73), and the time period (OR 1.85, 95% CI: 1.41-2.42) were significantly correlated with the use of chemotherapy. The use of chemotherapy appears to be increasing in stage IV CRC. Patients treated with curative intention or who underwent primary tumor resection were more likely to receive chemotherapy. Despite a known benefit of chemotherapy in elderly patients, a differential use of chemotherapy was noted in this population. 2015 S. Karger AG, Basel

    Long-term local control in Glioblastoma is rarely achieved and nearly all patients relapse. In this study we evaluated the clinical effect of different treatment approaches in recurrent patients. Forty-three patients, with median age of 51 years were evaluated for salvage treatment: re-resection and/or re-irradiation plus chemotherapy or chemotherapy alone. Response was recorded using the Response Assessment in Neuro-Oncology criteria. Hematologic and non-hematologic toxicities were graded according to Common Terminology Criteria for Adverse Events 4.0. Twenty-one patients underwent chemotherapy combined with local treatment, surgery and/or radiation therapy, and 22 underwent chemotherapy only. The median follow up was 7 months (range 3-28 months). The 1 and 2-years Progression Free Survival was 65 and 10 % for combined treatment and 22 and 0 % for chemotherapy alone (p < 0.01). The 1 and 2-years overall survival was 69 and 29 % for combined and 26 and 0 % for chemotherapy alone (p < 0.01). No toxicity greater than grade 2 was recorded. These data showed that in glioblastoma recurrence the combination of several approaches in a limited group of patients is more effective than a single treatment alone. This stress the importance of multimodality treatment whenever clinically feasible.

    Despite recent progress in systemic chemotherapy, the prognosis of gastric cancer patients with peritoneal metastasis (P1) or positive peritoneal cytology findings (CY1) is still poor. We developed a regimen combining intraperitoneal (IP) paclitaxel (PTX) with S-1 and PTX, which can produce notable efficacy with regard to peritoneal lesions. Surgery after response to combination chemotherapy is a promising option for P1 or CY1 gastric cancer. A retrospective study was performed to evaluate the safety and efficacy. This study enrolled 100 primary P1 or CY1 gastric cancer patients treated with IP PTX plus S-1 and PTX at the University of Tokyo Hospital between 2005 and 2011. Radical gastrectomy was performed when peritoneal cytology findings became negative, and the disappearance or obvious shrinkage of peritoneal metastasis was confirmed by laparoscopy. The same chemotherapy regimen was restarted after surgery and repeated with appropriate dose reduction. Gastrectomy was performed in 64 (P1 56, P0CY1 8) of 100 (P1 90, P0CY1 10) patients. R0 resection was achieved in 44 patients (69%). The median survival time was 30.5 months [95% confidence interval (CI) 23.6-37.7 months] from the initiation of intraperitoneal chemotherapy and 34.6 months (95% CI 26.8-39.4 months) from the diagnosis of gastric cancer. Postoperative complications included anastomotic leakage and pancreatic fistula, each in two patients, which were cured conservatively. There were no treatment-related deaths. The median survival time of the 36 patients who did not undergo surgery was 14.3 months (95% CI 10.0-17.8 months). Surgery after response to intraperitoneal and systemic chemotherapy is safe and may prolong the survival of P1 and CY1 gastric cancer patients.

    Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare, clinically aggressive hematologic malignancy that most commonly manifests as cutaneous lesions with or without bone marrow involvement and leukemic dissemination. The demonstration of tumor cells with the characteristic immunophenotype with expression of CD56, generally CD4 and dendritic cell antigens (CD123, cyTCL-1, HLA-DR), in the absence of myeloid or lymphoid lineage markers is required for the diagnosis. Responses to chemotherapy are initially satisfactory, with frequent systemic and central nervous system relapses. We report a 24 year-old male with BPDCN, initially diagnosed and treated as non-Hodgkin CD4+ T-cell lymphoma, with initial complete remission who evolved with early central nervous system relapse. A second attempt of chemotherapy failed and the patient died two months later.

    Over the past several decades, outcomes for patients with rectal cancer have improved considerably. However, several questions have emerged as survival times have lengthened and quality of life has improved for these patients. Currently patients with locally advanced rectal cancer (LARC) are often recommended multimodality therapy with fluoropyrimidine-based chemotherapy (CT) and radiation followed by total mesorectal excision (TME), with consideration given to FOLFOX before chemoradiotherapy (CRT). Recently, Garcia-Aguilar and colleagues reported in Lancet Oncology that the addition of mFOLFOX6 administered between CRT and surgery affected the number of patients achieving pathologic complete response (pathCR), which is of great interest from the standpoint of pursuit of optimal timing of systemic CT delivery. This was a multicenter phase II study consisting of 4 sequential treatment groups of patients with LARC, and they reported that patients given higher number CT cycles between CRT and surgery achieved higher rates of pathCR than those given standard treatment. There was no association between response improvement and tumor progression, increased technical difficulty, or surgical complications. Ongoing phase III clinical trial further assessing this strategy might result in a paradigm shift. PMID:26889491

    Based on prior reports suggesting a positive correlation between fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET)/CT and total sperm count and concentration, we sought to identify changes in testicular FDG uptake over the course of chemotherapy in young men with Hodgkin's lymphoma. Fifty-two patients with a mean age of 24.2 years (range 15.5-44.4) at diagnosis monitored with FDG PET/CT to assess treatment response for Hodgkin's lymphoma were selected for this retrospective analysis under an Institutional Review Board waiver. Of the patients, 26 were treated with a chemotherapy regimen known to cause prolonged and sometimes permanent azoospermia (BEACOPP--bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone) and 26 with a regimen known to have a much milder effect on gonadal function (ABVD--doxorubicin, bleomycin, vincristine, and dacarbazine). Each patient underwent one FDG PET/CT before treatment and at least one FDG PET/CT after start of chemotherapy. In all examinations, FDG activity was measured in the testes with different quantification metrics: maximum standardized uptake value (SUVmax), SUVmean, functional volume (FV) and total testicular glycolysis (TTG), and blood pool activity determined (SUVmean). Testicular FDG uptake (SUVmax) was significantly associated with blood pool activity (p < 0.001). Furthermore, testicular FDG uptake metrics incorporating volume (e.g., FV and TTG) were associated with age. There was no significant change in SUVmax, SUVmean, FV, and TTG from the PET/CT at baseline to the PET/CTs over the course of chemotherapy either for patients treated with BEACOPP or for patients treated with ABVD. For patients undergoing chemotherapy for Hodgkin's lymphoma, there is a significant association between testicular FDG uptake and blood pool activity, but no significant changes in FDG uptake over the course of chemotherapy. Therefore, FDG uptake may not be a feasible surrogate

    Granulosa cell tumors (GCTs) are rare, and the role of chemotherapy in their management is not clearly defined. We performed a retrospective cohort study of GCT patients diagnosed from January 1996 through June 2013 at the Memorial Sloan Kettering Cancer Center, comparing those who received adjuvant chemotherapy to those who did not. Differences between groups were assessed using the log-rank test. Statistical significance was set at p<0.05. Of 118 patients, 10 (8%) received adjuvant chemotherapy (1 [1%] of 103 stage I and 9 [60%] of 15 stage II-IV patients). Thirty-two patients (27%) experienced disease recurrence. Four patients had residual disease after initial surgery, and all received adjuvant chemotherapy; each recurred within 24.3 months (median PFS, 8.2 months). The time to first recurrence was longer in patients who did not receive adjuvant chemotherapy. For patients with recurrent disease, receiving chemotherapy after surgery for first recurrence did not seem to improve time to second recurrence versus surgery alone (HR 0.98; p=0.965). Additionally, 12 patients (10%) had a previous diagnosis of breast cancer-an incidence rate 3.22 times higher than Surveillance, Epidemiology, and End Results (SEER) data predicts (p<0.001). Although the numbers were small, in this analysis chemotherapy was not found to improve the recurrence-free interval of patients with GCTs, a finding that requires prospective validation. Residual disease after surgery was associated with poor prognosis. Finally, there was a significantly higher than expected incidence of antecedent breast cancer in this population, an association that deserves further exploration. Copyright © 2015 Elsevier Inc.

    Intraperitoneal (IP) chemotherapy is a preferable treatment option for peritoneal carcinomatosis of malignancies by delivering chemotherapeutic drugs into the abdominal cavity. A persistent major challenge in IP chemotherapy is the need to provide effective drug concentration in the peritoneal cavity for an extended period of time. In the present work, the thermosensitive hydrogel system (PTX/PECT(gel)) assembled by PTX (paclitaxel)-loaded amphiphilic copolymer (PECT, poly (ε-caprolactone-co-1,4,8-trioxa [4.6]spiro-9-undecanone)-poly(ethylene glycol)-poly (ε-caprolactone-co-1,4,8-trioxa [4.6]spiro-9-undecanone)) nanoparticles was developed for sustained IP chemotherapy of peritoneal carcinomatosis model. Cytotoxicity assay indicated that PECT hydrogel was biocompatible with very low cytotoxicity and PTX/PECT(gel) had enhanced cytotoxicity than free PTX. In vivo toxicity study demonstrated the biocompatibility and biosafety of PECT hydrogel as an IP chemotherapy carrier. The fluorescence imaging method was employed to monitor the intraperitoneal degradation of PECT hydrogel by labeling PECT with rhodamine B. PECT hydrogel with the dose of 200μL showed about 8days' retention time and most of the injected hydrogel was located in the intestine. The anti-tumor efficacy study was carried out in mice bearing CT26 intraperitoneal ascites fluid as colorectal peritoneal carcinomatosis model. The result showed that intraperitoneal administration of PTX/PECT(gel) could effectively suppress growth and metastasis of CT26 peritoneal carcinomatosis in vivo, compared with Taxol® group. The pharmacokinetic studies demonstrated that PTX/PECT(gel) could improve the bioavailability of PTX by being formulated in PECT hydrogel. Overall, sustained drug concentration at peritoneal levels in combination with drug in the form of nanoparticle contributes to the enhanced anti-tumor efficacy. Thus, our results suggested that PTX/PECT(gel) may have great potential applications in IP

    Predicting survival is uniquely difficult in patients with pancreatic cancer who receive chemotherapy. The authors developed a systemic inflammation response index (SIRI) based on peripheral neutrophil, monocyte, and lymphocyte counts and evaluated the ability of the SIRI to predict the survival of patients with pancreatic cancer who received chemotherapy. The SIRI was developed in a training set of 177 patients who had advanced pancreatic cancer and received palliative chemotherapy. The ability of the SIRI to predict a patient's survival after chemotherapy was validated in 2 independent cohorts (n = 397). Compared with patients who had an SIRI <1.8, patients in the training cohort who had an SIRI ≥1.8 had a shorter time to progression (TTP) (hazard ratio [HR], 2.348; 95% confidence interval, 1.559-3.535; P = .003) and shorter overall survival (OS) (HR, 2.789; 95% confidence interval, 1.897-4.121; P < .001). Comparable TTP and OS findings were observed in 2 independent validation cohorts. Multivariate analysis confirmed that the SIRI was an independent prognostic factor for both TTP and OS. In addition, compared with no change, an increase in the SIRI at week 8 was associated with poor TTP and OS, whereas a decrease in the SIRI was associated with improved outcomes. In addition, high SIRI scores were correlated with higher serum levels of interleukin 10, C-C motif chemokine ligand 17 (CCL17), CCL18, and CCL22 and with a shortened TTP. The SIRI can be used to predict the survival of patients with pancreatic adenocarcinomas who receive chemotherapy, potentially allowing clinicians to improve treatment outcomes by identifying candidates for aggressive therapy.

    The importance of nursing theory and models for the development of the nursing profession is becoming increasingly evident in literature. This article demonstrates the use of the Betty Neuman Systems Model (NSM) to assess, as well as determine the predictors of chemotherapy-induced nausea and vomiting (CINV) in patients diagnosed with breast cancer receiving doxorubicin-based chemotherapy. The selection of the model for practice reflects the congruency between the level of severity of CINV and the patient-related risk factors. In addition, the NSM was used to determine the appropriate nursing interventions necessary to strengthen the flexible lines of defense and the lines of resistance in addition to maintaining system stability.

    To improve the treatment results for locally advanced head and neck cancer, chemoradiation therapy by radiotherapy, systemic chemotherapy with 5-fluorouracil (5FU) and nedaplatin (NDP), and intra-arterial therapy using carboplatin (CBDCA) was performed. Thirty-two patients were entered into the study between July 1997 and August 2002. According to the TNM staging (1997), 14 patients had stage III lesions, and 19 patients had stage IV (M0) lesions. Alternating chemoradiotherapy was performed by the following regimen. Initially, systemic chemotherapy was administered, followed by 4 weeks of radiotherapy (36Gy/20 fractions; wide field irradiation) starting 2 days after chemotherapy, a second course of systemic chemotherapy 2 days after radiotherapy, and a second course of a reduced field radiotherapy (30Gy/15 fractions) 2 days after chemotherapy. Arterial injection therapy was administered in the latter half of radiotherapy after the end of the second course of systemic chemotherapy. For systemic chemotherapy, 5FU at 3500mg/m(2)/120h was intravenously administered for 5 days (Days 1-5), and NDP at 120mg/m(2)/6h was administered on Day 6. An intra-arterial agent using CBDCA was continuously infused by a portable electrical pump for 4 (to 6) weeks. The total dose of CBDCA was AUC 6 as established by Calvert's formula. The 5-year local control rate was 59%. The 5-year overall survival rate was 51%. There were no clinically significant adverse effects. Chemoradiation therapy by radiotherapy, systemic chemotherapy, and intra-arterial chemotherapy for locally advanced head and neck cancer may be useful for improving treatment results.

  14. Anticancer chemotherapy

    Despite troubled beginnings, anticancer chemotherapy has made significant contribution to the control of cancer in man, particularly within the last two decades. Early conceptual observations awakened the scientific community to the potentials of cancer chemotherapy. There are now more than 50 agents that are active in causing regression of clinical cancer. Chemotherapy's major conceptual contributions are two-fold. First, there is now proof that patients with overt metastatic disease can be cured, and second, to provide a strategy for control of occult metastases. In man, chemotherapy has resulted in normal life expectancy for some patients who have several types of metastatic cancers, including choriocarcinoma, Burkitt's lymphomas, Wilm's tumor, acute lymphocytic leukemia, Hodgkins disease, diffuse histiocytic lymphoma and others. Anticancer chemotherapy in Veterinary medicine has evolved from the use of single agents, which produce only limited remissions, to the concept of combination chemotherapy. Three basic principles underline the design of combination chemotherapy protocols; the fraction of tumor cell killed by one drug is independent of the fraction killed by another drug; drugs with different mechanisms of action should be chosen so that the antitumor effects will be additive; and since different classes of drugs have different toxicities the toxic effects will not be additive.

    To determine whether necrosis induced by pre-operative chemotherapy correlates with the rate of systemic and local relapse, may change the pattern of relapse and/or may modify the chance of success of post-relapse treatments, we evaluated 881 patients with non-metastatic osteosarcoma of the extremities treated with five different protocols of neoadjuvant chemotherapy and surgery at the same institution between 1983 and 1999. The 5-year disease-free survival (DFS) and overall survival (OS) correlated significantly with the histological response to chemotherapy. Five-year DFS and OS in good and poor responders were 67.9% versus 51.3% (P < 0.0001) and 78.4% versus 63.7% (P < 0.0001), respectively. The prognostic value of the histological response was valid only for osteoblastic and telangiectatic osteosarcoma subtypes. Nonetheless, since they represent more than 70% of all osteosarcomas, we conclude that chemotherapy-induced necrosis has a significant prognostic value, regardless of the type of chemotherapy performed after surgery.

    Introduction: Patients with metastatic hormone sensitive prostate cancer (mHSPC) have traditionally been treated with androgen deprivation therapy (ADT). Recently, there has been a demonstration of a survival benefit with the addition of docetaxel to ADT from three large randomized controlled trials. This review summarizes these trials, draws comparisons between the trials, and attempts to provide critical evidence-based recommendation on the role of docetaxel in mHSPC. Methods: Of the two published (GETUG-AFU, Chemo-Hormonal therapy vs. Androgen Ablation Randomized Trial for Extensive Disease in prostate cancer [CHAARTED]) and one presented trial (STAMPEDE) an analysis of the study design, patient characteristics, outcomes, variables, and a critical comparison between the trials was performed for making practice recommendations. Results: All the three trials demonstrated statistically significant progression free survival with the addition of docetaxel to ADT in mHSPC. However, while CHAARTED trial demonstrated a significant survival benefit with addition of docetaxel to ADT in patients with high volume mHSPC, GETUG-AFU failed to demonstrate statistically significant survival benefit although there was an absolute difference in survival between the two arms, with lower sample size and statistical power compared to CHAARTED. The largest study, STAMPEDE, reported a 22 month survival benefit in patients with M1 disease with statistical significance; with subgroup analysis of high volume and low volume disease patients yet to be reported. Conclusion: After a careful comparison between the trials, we conclude that systemic docetaxel chemotherapy within 4 months of initiating ADT for metastatic, high-volume HSPC should be considered the standard of care for patients with good performance status.

    A portable hybrid frequency domain (FD)-continuous wave (CW) Near-Infrared spectroscopy NIRS system has been developed for quantifying changes in total hemoglobin, oxygen saturation and water content in the breast during neoadjuvant chemotherapy. Simultaneous acquisition of two sets of 3 FD channels and 3 CW channels could be completed within 1 min. System calibration and homogeneous phantom measurement show phase variation less than 3% when PMT gain from 0.7 to 1.1 was used. The study of integrating this system into the workflow of clinical oncology practice is ongoing.

    Introduction We investigated the impact of modern chemotherapy regimens and bevacizumab following pulmonary metastasectomy (PM) from metastatic colorectal cancer (CRC). Methods A total of 122 consecutive patients who were curatively resected for pulmonary metastases of CRC in twelve oncology centers were retrospectively analysed between January 2000 and April 2012. Results Of 122 patients, 14 did not receive any treatment following PM. The remaining 108 patients received fluoropyrimidine-based (n = 12), irinotecan-based (n = 56) and oxaliplatin-based (n = 40) chemotherapy combinations. Among these, 52 patients received bevacizumab (BEV) while 56 did not (NoBEV). Median recurrence-free survival (RFS) was 17 months and median overall survival (OS) has not been reached at a median follow-up of 25 months after PM. Three and five-year OS rates were 66% and 53%, respectively. RFS and OS were similar, irrespective of the chemotherapy regimen or BEV use. Positive pulmonary margin, KRAS mutation status, and previous liver metastasectomy were negative independent prognostic factors for RFS, while pathologically confirmed thoracic lymph node involvement was the only negative independent prognostic for OS in multivariate analysis. Conclusions No significant RFS or OS difference was observed in respect to chemotherapy regimens with or without BEV in patients with pulmonary metastases of CRC following curative resection.

    To prevent oral chemotherapy prescription errors, we enhanced a prescription-writing module in an ambulatory electronic medical record. We sought to describe the enhancement, examine its performance to date, and identify opportunities for improvement. Enhancements to the oral chemotherapy writing module included weight- and body surface area-based dosing, fields for cancer diagnosis and intent of therapy (curative v palliative), and dose-limit warnings. We studied all prescriptions for 18 oral chemotherapies generated by oncology clinicians during the first 17 months after the safe prescribing enhancements were introduced, from May 1, 2010, to October 1, 2011. We examined the frequency with which clinicians used the new features, the number and type of alerts generated, and clinician actions in response to alerts. Six hundred clinicians generated 6,673 prescriptions for 2,043 patients. Six drugs-temozolomide, capecitabine, lenalidomide, hydroxyurea, imatinib, and erlotinib-accounted for 5,512 of all oral chemotherapy prescriptions (83%). Prescribers indicated the intent of therapy 13% of the time and listed the patient's cancer diagnosis 46% of the time. Prescribers customized their instructions using a free-text field in 64% of prescriptions. Clinicians' 6,673 prescription attempts triggered 395 dose-limit warnings (5%), mostly for temozolomide. Clinicians ignored most (96%) warnings, because current dosing recommendations exceeded the dose-limit warnings for the alerted medications. Oncology clinicians readily accepted features designed to enhance oral chemotherapy safety. Additional enhancements are needed to facilitate prescriptions with complex dosing regimens and to provide dose-limit warnings that reflect current clinical practice.

    For patients with liver metastases from gastric cancer (LMGC), combination chemotherapy with fluoropyrimidines and platinum agents has been recognized as standard treatment. However, the prognosis of hepatic progression after first-line treatment failure remains poor. When hepatic progression occurs, hepatic arterial infusion (HAI) chemotherapy may be helpful for preventing disease progression. To retrospectively assess the feasibility and efficacy of HAI chemotherapy using 5-fluorouracil, epirubicin, and mitomycin C (FEM) for patients with LMGC after failure of systemic S-1 plus cisplatin. We reviewed the records of patients who received HAI chemotherapy using FEM for LMGC that progressed during systemic S-1 plus cisplatin treatment while extrahepatic disease was decreased or did not appear. HAI chemotherapy was given as second-line therapy using 5-fluorouracil (330 mg/m(2) weekly), epirubicin (30 or 40 mg/m(2) every 4 weeks), and mitomycin C (2.7 mg/m(2) biweekly). Fourteen patients were analyzed. Toxicity of HAI chemotherapy was generally mild. The objective response rate was 42.9%, including a complete response rate of 14.3%. Median times to hepatic and extrahepatic progression were 9.2 and 7.4 months, respectively. Of 12 patients with documented progression after HAI chemotherapy, 10 patients (83.3%) received additional treatment, including irinotecan or taxanes. Overall, median survival was 12.7 months. Our findings suggest that HAI chemotherapy using FEM is a feasible and effective treatment for patients with LMGC after failure of systemic S-1 plus cisplatin. HAI chemotherapy employed in the second-line setting is useful for achieving long-term disease control of LMGC. © The Foundation Acta Radiologica 2015.

    Intravenous and intraperitoneal paclitaxel with S-1 is showing promising results in gastric cancer with peritoneal metastases. We herein report a successful conversion of unresectable to resectable disease using combination chemotherapy with trastuzumab. The patient was a 39-year-old woman with human epidermal growth factor receptor 2-positive gastric cancer with peritoneal, pulmonary and bilateral ovarian metastases. After 6 cycles of S-1 plus cisplatin with trastuzumab, followed by 15 cycles of intravenous and intraperitoneal paclitaxel with S-1 and trastuzumab, the pulmonary and peritoneal metastases exhibited complete response and no evidence of malignancy was found on diagnostic laparoscopy. We performed metastasectomy of the bilateral sizeable ovaries, followed by total gastrectomy. The patient had no recurrence for 16 months after the gastrectomy. Therefore, satisfactory response to systemic and intraperitoneal chemotherapy may convert unresectable to resectable disease, and primary tumor resection with ovarian metastasectomy may prolong survival. This combination chemotherapy has the potential of becoming a conversion therapy for gastric cancer with peritoneal metastases, even if ascites and ovarian metastases are extensive. PMID:28105352

    The present study aimed to evaluate benefit of hepatic arterial infusion chemotherapy (HAI) combined with systemic chemotherapy (SCT) for patients with colorectal liver metastases (CLMs) in a palliative setting. This was a retrospective single-center study including 43 consecutive patients with CLM after failure of standard SCT. Among them, 20 (47 %) patients underwent HAI combined with SCT (Group A) and 23 historical control patients who had received SCT with or without targeted agent treatment (Group B). The two groups had similar characteristics. Compared with SCT alone, HAI combined with SCT prolonged survival (median 19.8 vs. 9.0 months; P = 0.045). Median hepatic progression-free survival was significantly longer for HAI combined with SCT vs. SCT alone (median 8.1 vs. 4.7 months; P = 0.027), as were response rates (25 and 0 %; P = 0.038) and progression-free survival (median 5.7 vs. 3.0 months; P = 0.02). Three patients (15 %) achieved conversion to potentially curative surgery. Grade 3/4 toxicities for Group A and Group B were neutropenia (5 and 8.7 %, respectively), anemia (5 and 0 %, respectively), and hyperbilirubinemia (0 and 4.3 %, respectively). Other complications were mostly grade 1 or 2. HAI combined with SCT treatment can improve overall survival compared with SCT alone in highly advanced CLM refractory to intravenous chemotherapy.

    A 12 yr old male neutered domestic shorthair cat presented with worsening tachypnea of 1 mo duration and open mouth breathing. Radiographs revealed tracheal narrowing at the thoracic inlet. Computed tomography (CT) revealed a contrast enhancing 8-cm long fusiform mass within the dorsal tracheal membrane. Tracheobronchoscopy confirmed the presence of the tracheal mass at the thoracic inlet, and lymphoma was diagnosed based on uniformly atypical lymphoid cells on aspirated bronchoalveolar lavage fluid. The cat was treated with combination chemotherapy consisting of cyclophosphamide, vincristine, doxorubicin, and prednisolone. Thoracic radiographs and CT performed 1 mo after completion of the 6 mo chemotherapy protocol revealed resolution of the tracheal mass. The cat remained clinically normal at 21 mo after treatment.

  4. Metronomic chemotherapy.

    Chemotherapy drugs are usually administered at doses that are high enough to result in an obligatory break period to allow for the observation of potential side effects and institution of supportive care, if required. In recent years, efforts to administer chemotherapy on a more continuous basis, with a much shorter break period, or none at all, have received increased interest, and the practice has come to be known as metronomic chemotherapy. The basis for success with this currently investigational approach may be rooted in continuous drug exposure to susceptible cancer cells, inhibition of tumor blood vessel growth-a process known as tumor angiogenesis, and/or alterations in tumor immunology. Increased benefit also appears to occur when metronomic chemotherapy is used in combination with newer, targeted antiangiogenic agents, and therefore represents a promising approach to combination therapy, particularly as targeted oncology drugs make their way into veterinary oncology applications. There is still much to be learned in this field, especially with regard to optimization of the proper drugs, dose, schedule, and tumor applications. However, the low cost, ease of administration, and acceptable toxicity profiles potentially associated with this therapeutic strategy make metronomic chemotherapy protocols attractive and suitable to veterinary applications.

    Previous reports have shown the effectiveness of adjuvant hepatic arterial infusion chemotherapy (HAIC) in pancreatic cancer. However, percutaneous catheter placement is technically difficult after pancreatic surgery. The purpose of this study was to evaluate the feasibility and outcome of HAIC using a coaxial technique compared with conventional technique for postoperative pancreatic cancer. 93 consecutive patients who received percutaneous catheter-port system placement after pancreatectomy were enrolled. In 58 patients from March 2006 to August 2010 (Group A), a conventional technique with a 5-Fr indwelling catheter was used and in 35 patients from September 2010 to September 2012 (Group B), a coaxial technique with a 2.7-Fr coaxial catheter was used. The overall technical success rates were 97.1 % in Group B and 86.2 % in Group A. In cases with arterial tortuousness and stenosis, the success rate was significantly higher in Group B (91.7 vs. 53.8 %; P = 0.046). Fluoroscopic and total procedure times were significantly shorter in Group B: 14.7 versus 26.7 min (P = 0.001) and 64.8 versus 80.7 min (P = 0.0051), respectively. No differences were seen in the complication rate. The 1 year liver metastasis rates were 9.9 % using the conventional system and 9.1 % using the coaxial system (P = 0.678). The overall median survival time was 44 months. There was no difference in the survival period between two systems (P = 0.312). The coaxial technique is useful for catheter placement after pancreatectomy, achieving a high success rate and reducing fluoroscopic and procedure times, while maintaining the safety and efficacy for adjuvant HAIC in pancreatic cancer.

    Conventional cancer treatments rely on radiotherapy and chemotherapy. Such treatments supposedly mediate their effects via the direct elimination of tumor cells. Here we show that the success of some protocols for anticancer therapy depends on innate and adaptive antitumor immune responses. We describe in both mice and humans a previously unrecognized pathway for the activation of tumor antigen-specific T-cell immunity that involves secretion of the high-mobility-group box 1 (HMGB1) alarmin protein by dying tumor cells and the action of HMGB1 on Toll-like receptor 4 (TLR4) expressed by dendritic cells (DCs). During chemotherapy or radiotherapy, DCs require signaling through TLR4 and its adaptor MyD88 for efficient processing and cross-presentation of antigen from dying tumor cells. Patients with breast cancer who carry a TLR4 loss-of-function allele relapse more quickly after radiotherapy and chemotherapy than those carrying the normal TLR4 allele. These results delineate a clinically relevant immunoadjuvant pathway triggered by tumor cell death.

    Toxic effects and chemoresistance are major hurdles in chemotherapy and to avoid these problems caused by traditional chemotherapeutic regimens, a new modality of drug administration called “metronomic chemotherapy” has emerged. Such regimen involves the frequent administration of conventional chemotherapeutic agents at very low doses to target activated endothelial cells in tumors, the advantages of which include minimal adverse effects and a rare chance of developing acquired drug resistance. Previously it was thought that they act by targeting angiogenesis, but recently additional mechanisms have been discovered which has established metronomic chemotherapy as a type of multi-targeted therapy. The knowledge gained from the preclinical studies of metronomic chemotherapy, along with clinical experience, will help to design better therapeutic protocols against cancer. Detailed pharmacogenomic and pharmacoproteomic studies on tumor endothelial cells and large multi-centered clinical trials, integrating bio-marker analyzes, are needed to investigate and validate the best treatment combinations for each tumor type and patient population.

    Neoadjuvant chemotherapy for invasive bladder cancer, involving a regimen of M-VAC, can manage micrometastasis and improve the prognosis. However, some patients suffer from severe adverse drug reactions without any effect, and no method yet exists for predicting the response of an individual patient to chemotherapy. Our purpose in this study is to establish a method for predicting the response to the M-VAC therapy. We analyzed gene-expression profiles of biopsy materials from 40 invasive bladder cancers using a cDNA microarray consisting of 27 648 genes, after populations of cancer cells had been purified by laser-microbeam microdissection. We identified 14 predictive genes that were expressed differently between nine responder and nine non-responder tumors and devised a prediction-scoring system that clearly separated the responder group from the non-responder group. This system accurately predicted the clinical response for 19 of the 22 additional test cases. The group of patients with positive predictive scores had significantly longer survival times than that with negative scores. As real-time RT-PCR data were highly concordant with the cDNA microarray data for those 14 genes, we developed a quantitative RT-PCR-based prediction system that could be feasible for routine clinical use. Taken together, our results suggest that the sensitivity of an invasive bladder cancer to the M-VAC neoadjuvant chemotherapy can be predicted by expression patterns in this set of genes, a step toward achievement of "personalized therapy" for treatment of this disease.

    Hepatic artery chemotherapy was given to 36 patients, using totally implantable devices consisting of a port and external pump. Twenty-seven patients had inoperable liver metastases of colorectal origin. The infusion system was inserted by laparotomy into the hepatic artery via the gastroduodenal artery. There was no operative mortality. Thirteen infusion systems could not be used for chemotherapy due to dislodgement, early death and lack of follow-up. FUdR was infused every two weeks. There were minor local complications like thrombosis of the system and dislodgement of the port. Toxic effects could be managed by reducing the dose. Response to chemotherapy was evaluated by survival, clinical condition, CEA, ultrasound and CT six months after onset of arterial chemotherapy. Ten/twenty-three patients (43%) responded to therapy, eight of them died on the average 19 months after initial chemotherapy. Six patients were non-responders, seven had stable disease. Five/ten patients developed extrahepatic metastases. Mean survival time was 13.1 months, mean interval until relapse 10.6 months. PMID:2149279

    To date, no reliable markers are available to predict response to or to assess prognosis after preoperative systemic chemotherapy (PST) in patients with locally advanced breast cancer. Previous studies demonstrated that elevated levels of soluble E-cadherin (sE-cadherin), a product of proteolytic cleavage of cell surface E-cadherin, are associated with higher risk for metastatic disease and poor prognosis in various tumor types. We, therefore, hypothesized that serum sE-cadherin levels measured before PST may correlate with pathological response. In a retrospective analysis, sE-cadherin levels were measured in sera of 108 female patients with histologically proven breast cancer before initiation of PST by using a commercially available quantitative sandwich enzyme immunoassay technique. Patients received a median number of 4 (range 3-6) cycles of anthracyline-based chemotherapy. The median patient age was 51.5 (range 21-71) years. Tumor size was measured clinically and translated into the tumor-node-metastasis (TNM)-system before the start of chemotherapy. Histopathological response in surgically removed specimens was evaluated using a modified Sinn regression score. In univariate analyses the correlations between levels of sE-cadherin and pathological response to PST were calculated. The histopathological regression scores correlated significantly with tumor grading (p=0.045), clinical lymph node status before PST (p=0.031) and sE-cadherin levels (p=0.039). No correlation was seen between histopathological regression scores and hormone receptor and menopausal status as well as Her2-neu status. sE-cadherin may be a marker predicting response to PST for patients with breast cancer. Our findings warrant further evaluation of sE-cadherin in a prospective trial. Copyright © 2013 The Canadian Society of Clinical Chemists. Published by Elsevier Inc. All rights reserved.

    Bladder cancer is the most frequent among the urothelial tumors, and it is responsible for about 2% of all cancer mortality worldwide. The mainstay of chemotherapy treatment, both for muscle-invasive and metastatic disease, is cisplatin-based regimens. In recent years, ground-breaking results have been achieved with immunotherapy, which have led to important breakthroughs in the bladder cancer treatment scenario, with the approval of several new agents. New insights derive from a greater characterization of the tumor genome, which could lead to developing new therapies, more personalized, in the near future.

    Because numerous barriers hinder the assessment and management of chemotherapy-induced peripheral neuropathy in clinical practice, the Carevive Care Planning System, a novel Web-based platform, was developed to address these barriers. It provides patients an opportunity to report their symptoms before their clinic visit and generates customizable care plans composed of evidence-based management strategies. The purpose of this study was to evaluate patient and provider perspectives of feasibility, usability, acceptability, and satisfaction with the Carevive platform. We used a single-arm, pretest/posttest, prospective design and recruited 25 women with breast cancer who were receiving neurotoxic chemotherapy and six advanced practice providers from an academic hospital. At three consecutive clinical visits, patients reported their neuropathy symptoms on a tablet via the Carevive system. The Diffusion of Innovations Theory served as an overarching evaluation framework. The Carevive platform was feasible to use. However, patients had higher ratings of usability, acceptability, and satisfaction with the platform than did the providers, who disliked the amount of time required to use the platform and had difficulty logging into Carevive. If issues regarding provider dissatisfaction can be addressed, the Carevive platform may aid in the screening of neuropathy symptoms and facilitate the use of evidence-based management strategies.

    Nanohybrid drug delivery systems have presented lots of characteristic advantages as an efficient strategy to facilitate oral drug delivery. Nonetheless, oral administration of chemotherapy agents by nanoparticulate delivery technology still faces great challenges owing to the multiple biobarriers ranging from poorly physicochemical properties of drugs, to complex gastrointestinal disposition and to presystemic metabolism. This review briefly analyzes a series of biobarriers hindering oral absorption and describes the multiple aspects for facilitating the intravenous-to-oral switch in cancer therapy. Moreover, the developed nanoparticulate drug delivery strategies to overcome the above obstacles are provided, including metabolic enzyme inhibition, enteric-coated nanocarriers, bioadhesive and mucus-penetrating strategies, P-gp inhibition and active targeting. On these foundations, the emerging trends of integrated hybrid nanosystems in response to the present low-efficiency drug delivery of any single approach are summarized, such as mixed polymeric micelles and nanocomposite particulate systems. Finally, the recent advances of high-efficiency hybrid nanoparticles in oral chemotherapy are highlighted, with special attention on integrated approach to design drug delivery nanosystems.

    The aim of this work was to develop a targeted drug delivery system with potentials for intravesical instilled chemotherapy of superficial bladder cancer. The amphiphilic diblock copolymer poly(ε-caprolactone)-b-poly(ethylene oxide) (PCL-b-PEO) was first conjugated with the cyclic (Arginine-Glycine-Aspartic acid-d-Phenylalanine-Lysine) (c(RGDfK)) and fluorescein isothiocyannate (FITC) via the functional terminal groups of hydrophilic block, and then assembled into micelles. The interaction between micelles and various model cells was well studied by means of confocal laser scanning microscopy and flow cytometry. The c(RGDfK) on the surface of the micelle was confirmed by (1)H NMR analysis and cell affinity with human glioblastoma-astrocytoma cells (U87MG). The cell viability of bladder cancer cells (T-24 cells) after incubation with doxorubicin (DOX) loaded polymeric micelles was evaluated by in vitro cytotoxicity assay. The results revealed that c(RGDfK) modified micelles showed strong affinity to T-24 cells and strong inhibitory effect on the proliferation of T-24 cells when doxorubicin drug was loaded, indicating the high affinity of c(RGDfK) to bladder cancer cells. The c(RGDfK) modified micelles assembled from PCL-b-PEO diblock copolymers developed in this study are of great potentials as nano-scaled drug delivery system for intravesical instilled chemotherapy of superficial bladder cancer.

    As is widely suspected, lysolipid dissociation from liposomes contributes to the intravenous instability of ThermoDox (lysolipid liposomes), thereby impeding its antitumor efficacy. This work evaluates the feasibility of a thermoresponsive bubble-generating liposomal system without lysolipids for tumor-specific chemotherapy. The key component in this liposomal formulation is its encapsulated ammonium bicarbonate (ABC), which is used to actively load doxorubicin (DOX) into liposomes and trigger a drug release when heated locally. Incubating ABC liposomes with whole blood results in a significantly smaller decrease in the retention of encapsulated DOX than that by lysolipid liposomes, indicating superior plasma stability. Biodistribution analysis results indicate that the ABC formulation circulates longer than its lysolipid counterpart. Following the injection of ABC liposome suspension into mice with tumors heated locally, decomposition of the ABC encapsulated in liposomes facilitates the immediate thermal activation of CO2 bubble generation, subsequently increasing the intratumoral DOX accumulation. Consequently, the antitumor efficacy of the ABC liposomes is superior to that of their lysolipid counterparts. Results of this study demonstrate that this thermoresponsive bubble-generating liposomal system is a highly promising carrier for tumor-specific chemotherapy, especially for local drug delivery mediated at hyperthermic temperatures.

    Invasive candidiasis has increased as nosocomial infection recently in cancer patients who receive systemic chemotherapy, and the timely risk assessment for developing such specific infection is crucial. Especially in those concomitantly with hypopituitarism, febrile neutropenia with candidiasis can cause severe stress and lead potentially to sudden fatal outcome when the temporal steroid coverage for the adrenal insufficiency is not fully administered. We report a 72-year-old male case diagnosed as non-small-cell lung cancer, Stage IIIA. He had received a steroid replacement therapy for the prior history of hypophysectomy due to pituitary adenoma with hydrocortisone of 3.3 mg/day, equivalent to prednisolone of 0.8 mg/day. This very small dosage of steroid was hardly supposed to weaken his immune system, but rather potentially led to an inappropriate supplementation of his adrenal function, assuming that the serum sodium and chlorine levels decreased. On Day 6 of second cycle of chemotherapy with carboplatin and paclitaxel, he developed sudden febrile neutropenia, septic shock and ileus, leading to death. After his death, the venous blood culture on Day 7 detected Candida albicans. Autopsy findings showed a massive necrotizing enterocolitis with extensive Candida invasion into submucous tissue. In conclusion, this case may suggest that (i) immediate initiation of antifungal therapy soon after the careful risk assessment of Candida infection and (ii) adequate administration of both basal steroid replacement therapy and temporal steroid coverage for febrile neutropenia might have improved his fatal outcome.

    The transplantable C1300 murine neuroblastoma has been characterized biochemically and an in vivo model for the screening of new therapeutic approaches to the treatment of neuroblastoma developed. Subcutaneous inoculation of A/J mice with 10)6) C1300 cells results in predictable tumor growth and animal death in 25 +/- 4 days. Tumor growth is Gompertzian, correlates with increases in tumor RNA and DNA content and with the rate of tumor DNA synthesis as measured by [3H] thymidine incorporation. The model proposed is based on the degree to which various therapeutic options are able to inhibit tumor DNA synthesis, and these observations have been confirmed autoradiographically. A single course of either cyclophosphamide (25, 50, 100 or 200 mg/kg), BCNU (2, 7.5, 15, or 30 mg/kg) or cytosine arabinoside (15, 30, 60, 90 mg/kg) resulted in dose-related inhibition of tumor DNA synthesis. The maximum decline in DNA synthesis that was produced by the highest dose of each agent was by 81%, 77% and 68% of untreated tumor values respectively. Adriamycin, however, even at lethal levels (10 mg/kg), did not elicit significant inhibition of tumor DNA synthesis. Radiotherapy (200 R, 500 R or 1000 R) also produced graded inhibition of tumor DNA synthesis. This model is potentially useful for the preclinical screening of therapuetic options in the treatment of neuroblastoma. Thus, single agent therapy, combination chemotherapy and combined radiotherapy and chemotherapy may be rapidly evaluated for possible clinical use.

    The aim of this study was to check the clinical predictive variables of the variance of the total cost by GHM for patients undergoing chemotherapy. 10 different hospitals registered 537 hospital stays and 1,535 day care sessions. The initial disease, metastases, other pathologies, participation to randomised trial were recorded. Each day health status, pain, stage of the protocol and the drugs, use of catheter, pump or chamber implant were noted. Work was measured separately for physicians and nurses per 24 hours using a visual analogy scale. Lab tests and drugs were recorded for each patient. The cost of the drugs explain 98% of the variance of the total cost for the day care and 50% for the hospitalisations. For the latter, beside the cost of drugs, the length of stay, labor, initial disease, age, pain and associated pathology are predictive variables. According to this results, we conclude that the drugs for chemotherapy should be paid separately. No other change should be made for day care. DRG for hospitalized patients should take into account initial disease, age and pain.

    Introduction The placement of intramammary marker clips has proven to be helpful for tumor localization in patients undergoing neoadjuvant chemotherapy and breast-conserving surgery. The purpose of our study was to investigate the feasibility of using a clip marker system for breast cancer localization and its influence on the imaging assessment of treatment responses after neoadjuvant chemotherapy. Patients and Methods Between March and June 2015, a total of 25 patients (n = 25), with a suspicion of invasive breast cancer with diameters of at least 2 cm (cT2), underwent preoperative sonographically guided core needle biopsy using a single-use breast biopsy system (HistoCore™) and intramammary clip marking using a directly adapted clip system based on the established O-Twist Marker™, before their scheduled preoperative neoadjuvant chemotherapy. Localization of the intramammary marker clip was controlled by sonography and digital breast tomosynthesis. Results Sonography detected no dislocation of intrammammary marker clips in 20 of 25 patients (80 %), while digital breast tomosynthesis showed accurate placement without dislocation in 24 patients (96 %) (p < 0.05). There was no evidence of significant clip migration during preoperative follow-up imaging after neoadjuvant chemotherapy. No complication related to the clip marking was noted and there was no difficulty in evaluating the treatment response to neoadjuvant chemotherapy. Among the breast-conserving surgeries performed, no cases were identified in which intraoperative loss of the marker clip had occurred. Conclusion Our study underscores the importance of intramammary marking clip systems before neoadjuvant chemotherapy. Placement of marker clips is advised to facilitate accurate tumor bed localization. With regard to digital breast tomosynthesis, its development continues to improve the quality of diagnostics and the therapy of breast cancer particularly for small breast cancer tumors or in

    Retinoblastoma (RB) is the most common childhood malignant intraocular tumor. Although enucleation and external beam radiotherapy have been historically used, today the most commonly used eye-sparing approach is chemotherapy. Chemotherapy can be used in both intraocular and extraocular RB cases. Chemotherapeutic agents may be applied in different ways, including systemic, subconjunctival, intra-arterial and intravitreal routes. The main purposes of application of systemic therapy are to reduce the tumor size for local treatment (chemoreduction), or to reduce the risk of metastasis after enucleation surgery (adjuvant therapy). Intra-arterial chemotherapy with the current name "super-selective intra-arterial infusion therapy" could be applied as primary therapy in tumors confined to the retina or as a secondary method in tumor recurrence. The most important advantage of intra-arterial therapy is the prevention of systemic chemotherapy complications. Intravitreal chemotherapy is administered in the presence of persistent or recurrent vitreous seeding. The term "extraocular RB" includes orbital invasion and metastatic disease. Current treatment for orbital invasion is neoadjuvant chemotherapy followed by surgical enucleation and adjuvant chemotherapy and radiotherapy after surgery. In metastatic disease, regional lymph node involvement, distant metastases, and/or central nervous system (CNS) involvement may occur. Among them, CNS involvement has the worst prognosis, remaining at almost 100% mortality. In metastatic disease, high-dose salvage chemotherapy and autologous hematopoietic stem cell rescue therapy are the possible treatment options; radiotherapy could also be added to the protocol according to the side of involvement.

    The purpose of this study was to assess retrospectively the sequential treatment of hepatic arterial infusion (HAI) chemotherapy followed by systemic therapy using oxaliplatin plus 5-flourouracil (5-FU) and leucovorin, namely, FOLFOX, for patients with liver metastases from colorectal cancer. We reviewed 20 patients with unresectable liver metastases from colorectal cancer. Patients were initially treated with HAI chemotherapy until disease progression (5-fluorouracil, 1000 mg/m{sup 2} intra-arterial infusion, weekly) and then with FOLFOX thereafter (FOLFOX4, n = 13; modified FOLFOX6, n = 7). Adverse events, tumor response, and time to progression for each therapy were evaluated retrospectively, and overall survival was estimated. Toxicity of HAI chemotherapy was generally mild. Of 20 patients, adverse events leading to treatment discontinuation occurred in only 1 patient (5%) during initial therapy using HAI chemotherapy, while 9 patients (45%) exhibited adverse events during subsequent FOLFOX therapy. For HAI chemotherapy and FOLFOX, objective response rates were 85.0% and 35.0%, respectively, and median time to progression was 11.6 and 5.1 months, respectively. Median overall survival was 30.1 months. In conclusion, the sequence of HAI chemotherapy followed by FOLFOX is a promising treatment strategy for the long-term use of active chemotherapeutic agents, leading to a superior tumor response and fewer toxic effects in patients with unresectable liver metastases from colorectal cancer.

    Self-expandable metallic stent (SEMS) placement is an accepted palliative therapy for management of acute malignant bowel obstruction in advanced colorectal cancer. Nevertheless, data are lacking on the effects of systemic chemotherapy combined with colorectal SEMS. The aim of this study was to investigate the safety and efficacy of palliative chemotherapy for advanced colorectal cancer combined with colorectal SEMS placement. This multicentre retrospective study included all consecutive advanced colorectal cancer patients who received first-line palliative chemotherapy combined with endoscopic stenting for colorectal cancer with obstruction. We analyzed the number of cycles and the type of combination used. The primary endpoint was overall survival. Secondary endpoints included progression-free survival, response rate, grade 3-4 toxicity and the outcomes of SEMS for malignant colorectal obstruction. A total of 38 patients were included. Among them, 25 patients received oxaliplatin and 5-fluorouracil combination chemotherapy. Objective response and stabilization occurred in 38 and 24% of patients, respectively. The median overall survival and progression-free survival from the start of chemotherapy were 18 and 5months, respectively. The objective response rate and overall disease control rate were 38 and 62%, respectively. Toxicity was generally acceptable. Major complications related to stenting included perforation (8%), stent migration (5%), and reobstruction secondary to tumor ingrowths (13%). Chemotherapy combined with colonic stenting as a first-line treatment seems to be a valid option in advanced colorectal cancer patients with malignant colorectal obstruction.

    In an evaluation of chemotherapy-induced peripheral neuropathy (CIPN), objectivity may be poor because the evaluation is determined by the patient's subjective assessment. In such cases, management of neuropathy may be delayed and CIPN symptoms may become severe. In this pilot study, we attempted an objective evaluation of CIPN using a quantitative pain measurement system (Pain Vision(®)). The subjects were patients with gynecologic cancer who underwent chemotherapy using taxane and platinum drugs. The grade of the peripheral sensory nerve disorder was based on the Common Terminology Criteria for Adverse Events (CTC-AE) ver. 4.0 and was evaluated before the initiation of therapy and up to six chemotherapy cycles. A symptom scale assessed by the patients using a peripheral neuropathy questionnaire (PNQ) was also evaluated. Simultaneously during these evaluations, graded electric current was applied from the probe to a fingertip and measured both the lowest perceptible current and lowest current perceived as pain by Pain Vision(®). From these values, the pain degree was calculated from the following formula: (pain perception current value - lowest perceptible current value) ÷ lowest perceptible current value × 100. We compared the pain degrees by Pain Vision(®) during CIPN development with the value obtained before chemotherapy initiation. Forty-one patients were enrolled. In the evaluation by a medical professional, 28 (64.3%) patients developed CIPN during 2.5 ± 1.1 chemotherapy cycles (mean ± standard deviation). The pain degree by Pain Vision(®) at grade 1 and 2 CIPN development according to the evaluation (CTC-AE) was significantly decreased compared to that before chemotherapy initiation (126.0 ± 114.5 vs. 69.8 ± 46.8, p = 0.001, and 126.0 ± 114.5 vs. 32.8 ± 32.6, p = 0.004). Changes in the pain degree by Pain Vision(®) were also found during scale B and C, D CIPN development in the patient evaluation (PNQ) (115.9 ± 112.4 vs. 70

    Our aim is to optically monitor the delivery of the chemotherapy drugs for brain tumours, particularly used in the central nervous system (CNS) lymphoma therapy. In vivo monitoring would help to optimize the treatment and avoiding unnecessary medications. Moreover, it would be beneficial to be able to measure which of the multi-regimen drugs actually do penetrate and how well into the brain tissue. There exist several potential optical measurement techniques to be utilised for the purpose. The most desired method would allow the detection of the drugs without using optical biomarkers as a contrast agent. In this case, for non-invasive sensing of the drug in the brain cortex, the drug should have a reasonably strong optical absorption band somewhere in the range between 600 nm and 1700 nm, and not directly coincident with the strong bands of haemoglobin or water. Alternatively, mid-infrared (MIR) range has the potential for invasive drug monitoring techniques. In this paper, we report the optical properties of several chemotherapy drugs used in CNS lymphoma therapy, such as rituximabi, cyclophosphamide and etoposide. We measured their transmittance and reflectance spectra in near-infrared (NIR) range, particularly 900 nm - 2500 nm, to be considered when choosing the in vivo monitoring method to be developed. The absorption and scattering coefficients were retrieved from the measurements and applying Beer's law. For the measurement of the sum of total transmission and reflection in NIR range we used integrating sphere with spektralo to enable calculation of the scattering coefficient.

    The purpose of this study is to evaluate the safety and efficacy of percutaneous CT-guided radiofrequency ablation (RFA) as a supplemental therapy after systemic chemotherapy for selected patients with advanced non-small cell lung cancer (NSCLC). We retrospectively reviewed the medical records of 220 patients with advanced NSCLC who were treated with platinum-doublet chemotherapy between January 2000 and January 2012. Among them, 49 patients underwent RFA as a supplemental therapy for tumors in partial response or stable diseases after first-line chemotherapy. The progression-free survival (PFS) was evaluated by Kaplan-Meier method. There were nine women and 40 men (median age, 60 years; range, 24-82 years), including 28 patients with stage IIIb cancer and 21 with stage IV cancer. All 49 patients (partial response, 23 patients; stable disease, 26 patients) underwent 67 RFA sessions for 61 targeted tumors after systemic chemotherapy. There were no procedure-related deaths. Pneumothorax requiring chest tubes developed in eight sessions (11.9%). Thirty-one patients (63.3%) had complete response, 12 patients (24.5%) had partial response, six patients (12.2%) had stable disease, and no patients had progressive disease. The median follow-up period was 19 months (range, 6-34), and the median PFS was 16 weeks (95% CI, 14.5-17.5). Percutaneous CT-guided RFA can be performed as a feasible minimally invasive supplemental therapy with satisfactory PFS after systemic chemotherapy for patients with advanced NSCLC.

    To evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM). We retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed. There was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable. Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.

  10. Targeted cancer therapy--are the days of systemic chemotherapy numbered?

    Targeted therapy or molecular targeted therapy has been defined as a type of treatment that blocks the growth of cancer cells by interfering with specific cell molecules required for carcinogenesis and tumor growth, rather than by simply interfering with all rapidly dividing cells as with traditional chemotherapy. There is a growing number of FDA approved monoclonal antibodies and small molecules targeting specific types of cancer suggestive of the growing relevance of this therapeutic approach. Targeted cancer therapies, also referred to as "Personalized Medicine", are being studied for use alone, in combination with other targeted therapies, and in combination with chemotherapy. The objective of personalized medicine is the identification of patients that would benefit from a specific treatment based on the expression of molecular markers. Examples of this approach include bevacizumab and olaparib, which have been designated as promising targeted therapies for ovarian cancer. Combinations of trastuzumab with pertuzumab, or T-DM1 and mTOR inhibitors added to an aromatase inhibitor are new therapeutic strategies for breast cancer. Although this approach has been seen as a major step in the expansion of personalized medicine, it has substantial limitations including its high cost and the presence of serious adverse effects. The Cancer Genome Atlas is a useful resource to identify novel and more effective targets, which may help to overcome the present limitations. In this review we will discuss the clinical outcome of some of these new therapies with a focus on ovarian and breast cancer. We will also discuss novel concepts in targeted therapy, the target of cancer stem cells. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Primary central nervous system non-Hodgkin’s lymphoma is a rare presentation, almost always of diffuse large B-cell type. Although there is no consensus regarding therapy for this condition, induction regimens are based on high-dose methotrexate and consolidation whole-brain radiotherapy, or, more preferred recently, blood–brain barrier penetrating drugs such as etoposide, cytarabine, and alkylating agents like temozolomide, ifosfamide, and lomustine. We present here four cases of relapsed/refractory primary central nervous system lymphoma treated with ESHAP (etoposide, solumedrol, high-dose cytarabine, and platinum) chemotherapy to complete remission, with the eligible patients proceeding to autologous transplantation. We want to draw attention to this interesting, relatively well tolerated, underused therapeutic option, in a setting where treatment options are scarce and evidence-based recommendations are lacking.

    Malignant Brenner tumors (MBTs) of the ovary are very rare, and their definition, biology, and treatment modality have not been established. This study investigated the clinical characteristics of MBTs and the importance of chemotherapy for recurrent disease. We conducted a retrospective analysis of 10 patients with MBT of the ovary treated at a single tertiary center from 1991 to 2013. The median age was 55.5 years (range, 37-68 years). Nine of the 10 patients were symptomatic. The median size of the ovarian tumors was 10.5 cm (range, 2.5-25.0 cm). The cancer antigen-125 level was elevated in three patients. Six patients had a stage I tumor, one had a stage II tumor, two had a stage III tumor, and one had a stage IV tumor. Six patients received systemic adjuvant chemotherapy after surgery. The mean follow-up duration was 54.5 months (range, 8-173 months). Disease recurrence occurred in four of the 10 patients. The median time to recurrence was 11 months (range, 9-18 months). Two patients with locoregional recurrence showed favorable results after chemotherapy, regardless of the initial stage of the tumor. The patient with the stage IIIC tumor is alive at 13 months after recurrence on current chemotherapy. The patient with the stage IV tumor showed no evidence of the disease > 12 years after the last chemotherapy. Lastly, two patients with distant recurrence died after showing a long-term survival of 49 months and 88 months, respectively, after recurrence and intensive chemotherapy. Our results showed that systemic chemotherapy is beneficial in patients with recurrence of a primary MBT of the ovary, especially in the locoregional recurrence. Copyright © 2015.

    Background Breast cancer is treated with many different modalities, including chemotherapy that can be given as a single agent or in combination. Patients often experience adverse events from chemotherapy during the cycles of treatment which can lead to economic burden. Objective The objective of this study was to evaluate costs related to chemotherapy-related adverse events in patients with metastatic breast cancer (mBC) in an integrated health care delivery system. Methods Patients with mBC newly initiated on chemotherapy were identified and the first infusion was defined as the index date. Patients were ≥18 years old at time of index date, had at least 6 months of health plan membership and drug eligibility prior to their index date. The chemotherapy adverse events were identified after the index date and during first line of chemotherapy. Episodes of care (EOC) were created using healthcare visits. Chart review was conducted to establish whether the adverse events were related to chemotherapy. Costs were calculated for each visit, including medications related to the adverse events, and aggregated to calculate the total EOC cost. Results A total of 1,682 patients with mBC were identified after applying study criteria; 54% of these patients had one or more adverse events related to chemotherapy. After applying the EOC method, there were a total of 5,475 episodes (4,185 single episodes [76.4%] and 1,290 multiple episodes [23.6%]) related to chemotherapy-related adverse events. Within single episodes, hematological (1,387 EOC, 33.1%), musculoskeletal/pain related (1,070 EOC, 25.6%), and gastrointestinal (775 EOC, 18.5%) were the most frequent adverse events. Patients with adverse events related to single EOC with anemia and neutropenia had the highest total outpatient costs with 901 EOC ($81,991) and 187 EOC ($17,017); these patients also had highest total inpatient costs with 46 EOC ($542,798) and 16 EOC ($136,768).

    To evaluate the efficacy, survival and toxicity in patients with brain metastases from non-small cell lung cancer (NSCLC), treated with concurrent systemic chemotherapy and whole brain radiation therapy (WBRT) or sequential systemic chemotherapy/WBRT. A total of 60 NSCLC patients with brain metastases were divided into two groups in this prospective clinical study: concurrent systemic chemotherapy and WBRT group (concurrent group) and sequential systemic chemotherapy/WBRT group (sequential group). Of 59 assessable patients, the overall response rate was 22.0%, and the brain response rate was 35.6%; the median progression-free survival time was 3.0 months, and the overall 1- and 2-year survival rates were 55% and 24.4%, respectively, with a median survival time of 16.0 months. The overall response rate was 20.0% in the concurrent group and 24.1% in sequential group (P > 0.05). The brain response rates of 43.3% in concurrent group and 27.6% in sequential group were also not significantly different (P > 0.05). The median progression-free survival time for the patients in the concurrent group was 3.0 months versus 4.0 months in the sequential group, and the median survival time was 16.0 months versus 13.0 months (all P > 0.05). The 1- and 2-year survival rates were 58.5% and 37.2% versus 52.9% and 18.9%, respectively, with a significant difference in the 2-year survival rate between the two groups (P = 0.011). In the sequential group, leukopenia was more frequent during chemotherapy than that in the concurrent group (P = 0.029). Concurrent systemic chemotherapy and WBRT is effective with tolerable adverse events in treating brain metastasis from NSCLC with an encouraging survival, and deserves further large sample and randomized multicenter clinical trials.

    Peritoneal metastasis is common in gastric cancer. It is difficult to treat and carries a poor prognosis. Intraperitoneal (IP) delivery of chemotherapy can attain a higher drug exposure in the peritoneal cavity but with reduced systemic toxicity. Therefore, we hypothesized that IP paclitaxel with systemic chemotherapy would be clinically beneficial for gastric cancer with peritoneal metastases. Patients with unresectable and/or recurrent gastric adenocarcinoma with peritoneal dissemination and/or positive peritoneal washing cytology were recruited. They underwent eight cycles of IP paclitaxel and systemic XELOX. The primary endpoint was 1-year overall survival rate and secondary endpoints were safety, response rate, and peritoneal cytological response. Patients who subsequently had no distant metastases and two consecutive negative peritoneal cytologies underwent conversion gastrectomy if there was no macroscopic evidence of peritoneal disease at diagnostic laparoscopy. Twenty-two patients were enrolled, receiving at least one cycle of IP paclitaxel at the time of reporting (data cutoff-March 11, 2016). The median number of cycles was 7.5. The median overall survival was 18.8 months, and the 1-year survival rate was 72.2%. One patient died of neutropenic sepsis. Of 19 evaluable patients with measurable disease, 7 (36.8%) achieved PR, 8 (42.1%) achieved SD, and 4 (21.1%) experienced PD. Peritoneal cytology turned negative in 11 of 17 (64.7%) patients. Six patients underwent conversion gastrectomy (4 R0, 2 R1) with a median survival of 21.6 months (range = 8.7-29.9 months). XELOX and IP paclitaxel appears to be an effective regimen in gastric cancer with peritoneal metastases. Conversion gastrectomy may be considered in patients with a favorable response.

    Purpose. To evaluate the effects of combined continuous transcatheter arterial infusion (CTAI) and systemic chemotherapy in patients with advanced pancreatic carcinoma. Methods. CTAI was performed in 17 patients with stage IV pancreatic cancer with (n = 11) or without (n = 6) liver metastasis. The reservoir was transcutaneously implanted with the help of angiography. The inferior pancreatic artery (IPA) was embolized to achieve delivery of the pancreatic blood supply through only the celiac artery. The systemic administration of gemcitabine was combined with the infusion of 5-fluorouracil via the reservoir. Treatment effects were evaluated based on the primary tumor size, liver metastasis, and survival time and factors such as tumor size, tumor location, and stage of pancreatic carcinoma; the embolized arteries were analyzed with respect to treatment effects and prognosis. Results. A catheter was fixed in the gastroduodenal artery and splenic artery in 10 and 7 patients, respectively. Complete peripancreatic arterial occlusion was successful in 10 patients. CT showed a decrease in tumor size in 6 of 17 (35%) patients and a decrease in liver metastases in 6 of 11 (55%) patients. The survival time ranged from 4 to 18 months (mean {+-} SD, 8.8 {+-} 1.5 months). Complete embolization of arteries surrounding the pancreas was achieved in 10 patients; they manifested superior treatment effects and prognoses (p < 0.05). Conclusion. In patients with advanced pancreatic cancer, long-term CTAI with systemic chemotherapy appeared to be effective not only against the primary tumor but also against liver metastases. Patients with successfully occluded peripancreatic arteries tended to survive longer.

    Response rates and overall outcome for patients who have failed first-line and in some cases second-line chemotherapy are as low as 12% and 7 months, respectively. The aim of this study is to evaluate the efficacy of hepatic arterial sulfonate hydrogel microsphere (drug-eluting beads), irinotecan preloaded therapy (DEBIRI) in metastatic colorectal cancer refractory to systemic chemotherapy. This was a multicenter multinational single-arm study of metastatic colorectal cancer patients who received DEBIRI after failing systemic chemotherapy from 10/2006 to 8/2008. Primary endpoints were safety, tolerance, tumor response rates, and overall survival. Fifty-five patients who had received prior systemic chemotherapy and who underwent a total of 99 DEBIRI treatments were reviewed. The median number of DEBIRI treatments was 2 (range 1-5), median treatment dose was 100 mg (range 100-200 mg), with total hepatic treatment of 200 mg (range 200-650 mg), with 86% of treatments performed as lobar infusion and 30% of patients treated with concurrent simultaneous chemotherapy. Adverse events occurred in 28% of patients with median grade of 2 (range 1-3) with no deaths at 30 days post procedure. Response rates were 66% at 6 months and 75% at 12 months. Overall survival in these patients was 19 months, with progression-free survival of 11 months. Hepatic arterial drug-eluting bead, irinotecan (DEBIRI) was safe and effective in treatment of metastatic colorectal cancer (MCC) refractory to multiple lines of systemic chemotherapy. DEBIRI is an acceptable therapy for treatment of metastatic colorectal cancer to the liver.

    The applicability and efficacy of a scalp cooling system were studied in 105 breast cancer patients receiving four cycles of adjuvant chemotherapy with mitoxantrone + cyclophosphamide (NC chemotherapy). Women accepting the scalp-cooling system were compared for alopecia both against those who refused and against a "reference" group of 109 patients similarly treated but without being offered a scalp-cooling system. Hair loss in the 105 study patients was evaluated by nurses using World Health Organization (WHO) criteria at each cycle of chemotherapy. Concomitantly, tolerance and side-effects of the helmet were also recorded in 48 accepting patients. Similarly to reference group patients, a subsample of 27 accepting patients self-assessed hair loss using a specific questionnaire measuring its frequency and severity and the distress associated with this symptom. Nurses' ratings ( n = 105) indicated that hair loss frequency was constantly lower, at each cycle of chemotherapy, in study patients with scalp-cooling system ( n = 77) than in those without ( n = 28). Differences between the two groups were statistically significant at cycles 1 and 3 ( P < 0.05). When compared with those reported by reference group patients ( n = 109), study patients' self-measures of alopecia frequency ( n = 27) provided even more marked results than those achieved by nurses (cycles 1-3: P < 0.01; cycle 4: P < 0.05). Tolerance was generally good and no scalp metastasis was observed among the 77 accepting patients followed up. This study demonstrates that scalp cooling was an effective method of protection against hair loss caused by NC chemotherapy. Its routine use as part of adjuvant chemotherapy, especially in cancers with low prevalences of scalp metastasis, should be seriously considered.

    Second-line therapy has consistently demonstrated survival benefit if compared with best supportive care; however, there is limited evidence whether further lines of treatment may improve the prognosis of advanced gastric cancer (AGC) patients. Starting from a real-world cohort of 868 AGC patients, we retrospectively analyzed baseline parameters, tumor characteristics, and treatment data of those treated with at least three lines. Categorical features were described through cross-tables and chi-square test. We explored the impact of treatment intensity and progression-free survival (PFS) experienced in previous lines on PFS and overall survival in third-line by uni- and multivariate Cox regression models and described by Kaplan-Meier estimator plot with log-rank test. Overall, 300 patients were included in the analysis. The most common site of primary tumor was gastric body; 45.3% of cancers had an intestinal histotype, 14% were human epidermal growth receptor 2 positive. In third-line, 45.7% of patients received a single-agent chemotherapy, 49.7% a combination regimen. Patients who had experienced a first-line PFS ≥6.9 months had a better prognosis compared with those who had achieved a shorter one. Consistently, a second-line PFS ≥3.5 months positively influenced the prognosis. Patients receiving a third-line combination regimen had better outcomes compared with those treated with a single-agent chemotherapy. Our real-world study confirms that selected AGC patients may receive third-line treatment. Longer PFS in previous lines or a more intense third-line treatment positively influenced prognosis. Further efforts are warranted to define the best therapeutic sequences, and to identify the optimal candidate for treatment beyond second-line. The benefit of third-line treatment to advanced gastric cancer patients is controversial. Our study depicts a real scenario of the clinical practice in Italy, confirming that a non-negligible proportion of patients receive a

    Conventional chemotherapy is the main treatment for cancer and benefits patients in the form of decreased relapse and metastasis and longer overall survival. However, as the target therapy drugs and delivery systems are not wholly precise, it also results in quite a few side effects, and is less efficient in many cancers due to the spared cancer stem cells, which are considered the reason for chemotherapy resistance, relapse, and metastasis. Conventional chemotherapy limitations and the cancer stem cell hypothesis inspired our search for a novel chemotherapy targeting cancer stem cells. In this review, we summarize cancer stem cell enrichment methods, the search for new efficient drugs, and the delivery of drugs targeting cancer stem cells. We also discuss cancer stem cell hierarchy complexity and the corresponding combination therapy for both cancer stem and non-stem cells. Learning from cancer stem cells may reveal novel strategies for chemotherapy in the future. PMID:26045975

    Primary cutaneous apocrine carcinoma (PCAC) is a rare and highly aggressive cutaneous adnexal type of tumor that has a high metastasis rate and a poor prognosis. Although there are several case reports describing the successful treatment of PCAC with chemoradiotherapy or molecular targeting therapy, no standard therapy for the treatment of advanced PCAC has been established yet. Since receptor activator of nuclear factor kappa-B ligand (RANKL) is expressed in cancers of apocrine origin, leading to immunosuppression at the tumor site, we hypothesized that targeting RANKL with denosumab might be useful for the treatment of PCAC. In this report, we describe a case with advanced PCAC on the scrotum successfully treated with systemic chemotherapy using carboplatin and paclitaxel, and radiotherapy followed by denosumab.

    A 73-year-old man underwent abdominoperineal resection for a rectal cancer. He developed a hip pain 3 years and 6 months after the surgery. A CT scan revealed a local recurrence in the perineum and multiple lung metastases in the bilateral lung. He received systemic chemotherapy consisting of XELOX with bevacizumab. Thereafter, the hip pain was slightly relieved. The hip pain worsened 1 year and 6 months after the recurrence. The border between the perineal tumor and skin was very narrow, and conventional radiation therapy could cause a perineal skin necrosis and subsequent poor wound healing. Therefore, we selected a Cyberknife treatment. The hip pain was relieved and a CT scan showed a reduction of the perineal tumor's size after the Cyberknife treatment. A Cyberknife treatment may be effective and promising as palliation for patients with local recurrence of rectal cancer.

    The use of chemotherapy to suppress replication of the human immunodeficiency virus (HIV) has transformed the face of AIDS in the developed world. Pronounced reductions in illness and death have been achieved and healthcare utilization has diminished. HIV therapy has also provided many new insights into the pathogenesis and the viral and cellular dynamics of HIV infection. But challenges remain. Treatment does not suppress HIV replication in all patients, and the emergence of drug-resistant virus hinders subsequent treatment. Chronic therapy can also result in toxicity. These challenges prompt the search for new drugs and new therapeutic strategies to control chronic viral replication.

    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.

    Children with neurofibromatosis type 1 (NF1) are predisposed to both brain tumors and cognitive deficits. While changes in white matter integrity after multimodal therapy are associated with cognitive dysfunction, the effect of isolated chemotherapy in NF1 is unknown. To determine whether chemotherapy is associated with white matter microstructural changes, we examined diffusion tensor imaging (DTI) in NF1 subjects. We reviewed DTI measures in tracts associated with cognition but free from tumor in 24 children with NF1-associated optic pathway gliomas unexposed to surgery or radiation. Twelve age-matched pairs were identified based on exposure to chemotherapy. A paired t-test was used to compare fractional anisotropy (FA) in tracts of interest between subjects with and without chemotherapy exposure. On paired t-test, FA was significantly lower in the corpus callosum (P = 0.015) and cerebellothalamic (P = 0.038) tracts of subjects exposed to chemotherapy. There was no effect of age or time from chemotherapy on the difference between groups. In multivariable analysis, FA of these tracts was associated with chemotherapy exposure after adjusting for age, tumor location, and DTI acquisition. In longitudinal measures, FA decreased after chemotherapy exposure while FA increased with age in unexposed subjects. Exposure to low-intensity chemotherapy in NF1 is associated with changes in white matter microstructure in tracts associated with cognition. Future studies should determine whether these changes are associated with cognitive decline. While chemotherapy may spare cognition relative to radiation and surgery, children with NF1 exposed to chemotherapy may benefit from early cognitive testing to allow for earlier intervention. © 2016 Wiley Periodicals, Inc.

    This prospective, open-label phase II study assessed the impact of liver-directed therapy with selective internal radiation therapy (SIRT) and systemic chemotherapy on progression-free survival (PFS) in liver-dominant metastatic pancreatic adenocarcinoma. Patients received yttrium-90-labelled ((90)Y) resin microspheres (SIR-Spheres; Sirtex Medical Limited, Sydney, Australia) as a single procedure on day 2 of the first weekly cycle of 5-fluorouracil (5FU; 600 mg/m(2)) with the option to switch to gemcitabine (1000 mg/m(2)) after 8 weeks of 5FU. Statistical analysis was conducted using Microsoft Excel (Microsoft Corporation, Redmond, Washington, USA). The primary endpoint of the study was PFS in the liver, with a median of ≥ 16 weeks defined as the threshold for clinical significance. PFS and overall survival (OS) were summarised by the Kaplan-Meier method using non-parametric estimates of the survivor function. Fourteen eligible patients were enrolled; ten had primary tumour in situ and eight had liver-only metastases. Patients received a median (90)Y activity of 1.1 GBq and 8 weekly doses of 5FU; seven patients received a median of two doses of gemcitabine. Disease control in the liver was 93% (two confirmed partial responses [PR], one unconfirmed PR, ten stable disease). Median reduction in cancer antigen 19-9 was 72%. Median PFS was 5.2 months in the liver, which met the primary endpoint of the study, and 4.4 months at any site. PFS was prolonged in those with a resected primary compared with patients with primary in situ (median 7.8 vs. 3.4 months; p = 0.017). Median OS was 5.5 months overall and 13.6 months in patients with a resected primary. Grade 3/4 adverse events occurred in eight (57%) patients during days 0-60. There was one sudden death and another patient who died from possible treatment-related liver failure 7.0 months after SIRT. SIRT and chemotherapy appears to be an effective treatment for liver metastases from pancreatic cancer, likely to be of

    Adenocarcinomas of the appendix represent a heterogeneous disease depending on the presence of mucinous histology, histologic grade, and stage. In the current study, the authors sought to explore the interplay of these factors with systemic chemotherapy in a large population data set. Patients in the National Cancer Data Base (NCDB) who were diagnosed with mucinous, nonmucinous, and signet ring cell-type appendiceal neoplasms from 1985 through 2006 were selected. Multivariable Cox proportional hazards regression models were developed. A total of 11,871 patients met the inclusion criteria for the current study: 50.3% had mucinous neoplasms, 40.5% had nonmucinous neoplasms, and 9.2% had signet ring cell-type neoplasms. The 5-year overall survival (OS) stratified by grade was similar among patients with American Joint Committee on Cancer stage I to stage III disease but not for those with stage IV disease. The median OS for patients with stage IV mucinous and nonmucinous tumors was 6.4 years and 2.3 years, respectively, for those with well differentiated histology (P<.0001) and was 1.5 years and 0.8 years, respectively, for those with poorly differentiated histology (P<.0001). In multivariable modeling for stage I to III disease, adjuvant chemotherapy improved OS for both mucinous and nonmucinous histologies, with hazard ratios (HRs) of 0.78 (95% confidence interval [95% CI], 0.68-0.89 [P = .0002]) and 0.83 (95% CI, 0.74-0.94 [P = .002]), respectively. For patients with stage IV disease, systemic chemotherapy significantly improved OS for those with nonmucinous (HR, 0.72; 95% CI, 0.64-0.82 [P<.0001]) but not mucinous (HR, 0.95; 95% CI, 0.86-1.04 [P = .2) histologies, although this was grade-dependent. The median OS for chemotherapy versus no chemotherapy was 6.4 years versus 6.5 years (P value not significant) for patients with mucinous, well-differentiated tumors and 1.6 years versus 1.0 years (P = .0007) for patients with mucinous, poorly

    This retrospective case series evaluates the outcome of 21 dogs with grade II stage 2 mast cell tumour (MCT) treated with adequate local therapy and adjuvant systemic chemotherapy (prednisone, vinblastine and CCNU). The median survival for all dogs was 1359 days (range, 188-2340). Median disease-free interval was 2120 days (149-2325 days). Dogs treated with surgery and chemotherapy had shorter survival (median, 1103 days; 188-2010 days) than those that underwent surgery, radiation therapy and chemotherapy as part of their treatment (median, 2056 days; 300-2340 days). Two patients had local recurrence in the radiation field and four patients had de novo MCT. Distant metastasis was not observed in any dogs. The results of this study suggest that, in the presence of loco-regional lymph node metastasis in grade II MCT, the use of prednisone, vinblastine and CCNU after adequate local-regional therapy can provide a median survival in excess of 40 months.

    Continuous therapy with cytotoxic drugs suppresses humoral immune function and may result in local infection. We present a case of orbital apex syndrome caused by Aspergillus infection during chemotherapy for metastatic colorectal cancer. A 74-year-old man with colorectal liver metastases under long-term continuous systemic chemotherapy presented with painful, progressive orbital apex syndrome. Magnetic resonance imaging disclosed a small enhancing lesion around the right ethmoid sinus. We initially diagnosed colorectal cancer metastasis and he underwent biopsy via the endoscopic endonasal transethmoid approach. However, pathological examination of the cultured specimen revealed Aspergillus fumigatus. The patient was treated with voriconazole and the orbital apex syndrome resolved after 1 month. Orbital aspergillosis is a life-threatening disease and should be listed as a differential diagnosis of uncommon local infections during continuous chemotherapy.

    The primary challenge of cancer therapy was the failure of most chemotherapeutics to accumulate in the tumors, additionally causing serious systemic side effects. We designed a tumor-targeting accumulated and locally triggered-release nanocarrier system to increase the intratumoral drug concentration and thus the efficacy of chemotherapy, based on gold nanorods (GNRs) and thermosensitive liposomes (TSLs). PEGylated GNRs could not only make nanocarriers to co-accumulate in tumors depending on enhanced permeability and retention (EPR) effect, but also generated heat locally under near-infrared (NIR) stimulation. CO2 bubbles were generated by the encapsulated ammonium bicarbonate (ABC) under hyperthermia, thus the co-encapsulated drug was released and local drug concentration was increased along with the disintegration of liposomal membrane. On the other hand, this dual-targeting system prevented the drug leakage in blood circulation or other organs while facilitated most of the active agents delivered to tumors. In vitro and in vivo experiments revealed high cytotoxicity and good affinity of HTSL to MDA-MB-435 cells when used synergistically with GNRs, but low toxicity to normal cells at the same condition. When combined with thermotherapy, the smart nanocarrier system held significant promise for future cancer treatment for their markedly improved therapeutic efficacy and decreased systemic toxicity.

    Neuroendocrine tumors (NETs) comprise a heterogeneous group of malignancies with various clinical presentations and evolution. NETs are often diagnosed at a late stage, when they are already metastatic. Treatment is currently based on traditional chemotherapies, such as streptozocin, with serious side effects. The favorable toxicity profile of the combination of 5-fluorouracil with oxaliplatin, together with its significant antitumor activity in several gastrointestinal malignancies, led to the evaluation of its efficacy and tolerability in patients with advanced grade 1/2 (G1/G2) NETs. The endpoints of the study were tumor response (according to the Response Evaluation Criteria in Solid Tumors 1.1), overall survival (OS), progression-free survival (PFS) and symptom improvement. From January, 2013 to January, 2015, during our Regional Multidisciplinary Tumor Board dedicated to NETs (RENATEN network), FOLFOX was recommended for the treatment of metastatic NETs as first-line therapy or after failure of other therapies. The inclusion criteria were metastatic, well-differentiated G1/G2 NETs, progressing within the last 3 months. Cases with previous antitumor therapy were allowed. The patients received modified FOLFOX-6 and were assessed every 3 months by computed tomography or magnetic resonance imaging examinations. A total of 31 patients were included. The median follow-up was 20 months [95% confidence interval (CI): 15–27]. Nine patients (29%) exhibited a partial response, and 13 (41%) achieved stable disease; the disease control rate was 70%. A total of 9 patients exhibited disease progression. The control rate was 78% for pancreatic and 65% for extrapancreatic NETs. The median OS was not reached; the 1- and 2-year OS rates were 89 and 70%, respectively (Fig. 1). No significant difference in OS was observed between the <5 and 5–20% Ki-67 subgroups (P=0.41) (Fig. 2A) or according to primary tumor location (P=0.71) (Fig. 2B). The median PFS was 14.1 months (95

    The objective of this study was to evaluate retrospectively one institution's experience treating pediatric central nervous system (CNS) pure germinomas with platinum-based chemotherapy followed by focal, reduced-dose irradiation. Eight patients were identified with localized, pure CNS germinomas from 1993 to 2004 at the authors' institution. The median age at diagnosis was 13 years (range 7-19). The median follow-up was 40 months (range 8-141). The tumor location was suprasellar in four, the pineal region in three, and the third ventricle in one. Irradiation was started a median of 20 weeks (range 17-22) from diagnosis and consisted of conformal fields to the primary site as determined by the initial diagnostic MR plus a 1.5- to 2-cm margin. Six of the eight patients received a dose of 3,060 cGy; two patients received 3,600 cGy. The 5-year actuarial event free survival was 71% (56-86%, 95% CI). Two patients suffered marginal (at field edge) failures and both were salvaged using reinduction platinum-based chemotherapy followed by cranial spinal irradiation and a boost to the primary tumor. The 5-year actuarial overall survival was 100%. There were no spinal failures. These data suggest that a reduction in both volume and dose (30.6-36 Gy) retains the excellent survival rates for patients with localized, pure germinomas of the CNS. A higher rate of ventricular relapse rate is observed, although salvage of those patients is feasible.

    Significant uncertainty exists regarding the efficacy of high-dose chemotherapy and autologous hematopoietic cell transplantation (AHCT) for the treatment of patients with primary systemic (AL) amyloidosis. We performed a systematic review and meta-analysis to evaluate the efficacy of AHCT versus conventional chemotherapy (CC) in patients with AL amyloidosis using methodology recommended by the Cochrane Collaboration. A comprehensive literature search yielded 820 studies. Twelve studies met the inclusion criteria: 1 randomized controlled trial (RCT), 2 other controlled studies, and 9 single-arm trials. The 1 RCT and 2 controlled studies compared AHCT and CC, and 9 single-arm studies assessed the efficacy of AHCT without a control. The pooled hazard ratio for overall survival (OS) in the 3 controlled studies was 1.79 (95% confidence interval [CI] = 1.11 to 2.91) favoring CC. The pooled proportion for mortality in the single-arm studies (n = 7) was 0.35 (95% CI = 0.25 to 0.46). The pooled odds ratio for complete hematologic response (CHR) from 2 controlled studies was 0.64 (95% CI = 0.25 to 1.64), indicating no difference between AHCT and CC. In the single-arm studies, the pooled proportion for CHR was 0.35 (95% CI = 0.26 to 0.44), and the pooled proportion for treatment-related mortality (TRM) was 0.12 (95% CI = 0.09 to 0.14). In the controlled studies, there was no heterogeneity for any outcome; however, in the single-arm studies, there was a significant heterogeneity for the outcomes of OS, CHR, renal response, and partial hematologic response. Our findings indicate that AHCT does not appear to be superior to CC in improving OS in patients with AL amyloidosis. But the quality of our evidence is low, indicating a need for well-designed and adequately powered RCTs to better address the role of AHCT in AL amyloidosis.

The objective was to assess the connection of fatigue perception and depression of caregivers, oncological team and oncological patients in oral chemotherapy to intravenous The study recruited 60 patients and 60 caregivers. The study was carried out on patients with lung, breast and colon cancer requiring chemotherapy, and family members were chosen as caregivers. Patients, caregivers and doctors filled in FACT-F and Zung questionnaires at the opening day of the medical record, after three and six cycles of chemotherapy, and three months after the end of the treatment. The Zung depression and Functional Assessment of Cancer therapy-Fatigue (FACT-F) showed: (a) on patients treated with intravenous therapy showed significantly higher levels of fatigue and depression than those of patients treated with oral therapy, even when the latter were treated for advanced disease; (b) on caregivers of patients treated with systemically administered therapies showed elevated levels of Fatigue and depression which proved to be significantly higher than those of caregivers of patients treated with oral therapies, even when treated for advanced disease; (c) on three oncologist has highlighted low levels of Fatigue and depression, for both types of patients, higher for patients with systemic therapy related to the management of side effects. The results showed that cancer patients and caregivers have high levels of fatigue and depression both related to the disease stage and to the mode of drug administration. It is necessary to provide cancer patients and caregivers with appropriate psychological support and preventive programs for secondary and relapse prevention.

    The purpose of this study was to evaluate CT arteriography (CTA) using an implantable port system in the detection of perfusion abnormalities occurring during hepatic arterial infusion chemotherapy (HAIC). In 51 patients with unresectable primary and metastatic liver tumors, who had implanted port systems for HAIC, CTA examinations through the infusion pump were performed. When perfusion abnormalities were found, selective angiography and/or digital subtraction angiography using the implantable port system were performed to determine the etiology. Forty-nine perfusion abnormalities were detected in 32 patients. Intrahepatic hypoperfusion was found in 24 cases. Of 11 patients in whom correction of the hypoperfusion was attempted, it was successful in 10. Of 13 patients in whom correction was not attempted, 6 patients showed progressive disease in nonperfused areas. Intrahepatic hyperperfusion was found in 14 cases, which showed no subsequent complication. Extrahepatic perfusion was found in 11 cases. We consider CTA to be useful in detecting perfusion abnormalities that may compromise HAIC. 22 refs., 3 figs., 3 tabs.

    To evaluate the efficacy and safety of a coaxial reservoir system with a non-braided spiral tip microcatheter and exclusive port for hepatic arterial infusion chemotherapy. In vitro evaluation included evaluation of pressure tolerance/flow rate of the coaxial reservoir system, and the strength of connection between the 2.7-F catheter and port. Due to the difficulty of implanting conventional reservoirs, coaxial reservoirs were implanted via the femoral artery of 80 patients. We implanted a non-braided 2.7-F microcatheter with a spiral shaped tip, 5-F catheter, and a port. Clinical assessment included evaluation of technical success and complications. In vitro evaluation of the coaxial reservoir at its maximum pressure load showed that flow rates for 300 mg I/mL iopamidol contrast medium were 0.25 ± 0.04 mL/s (undiluted), 1.03 ± 0.01 mL/s (50% dilution), and 2.91 ± 0.01 mL/s (30% dilution). Connection strength between the 2.7-F catheter and port was 13.4 ± 0.57 N. Percutaneous port catheter placement was successful in all patients (100%, n = 80). Complications included hepatic arterial occlusion (10%, n = 8), catheter tip dislocation (1.3%, n = 1), and catheter occlusion (1.3%, n = 1). A coaxial reservoir system with a non-braided microcatheter and exclusive port is safe and effective for difficulty of implanting conventional reservoir.

    Infectious complications are a major cause of morbidity and mortality from dose-intensive cancer chemotherapy. In spite of the importance of intestinal bacteria translocation in these infections, information about the effect of high-dose chemotherapy on gut mucosal immunity is minimal. We studied prophylactic ciprofloxacin (Cipro) treatment on irinotecan (CPT-11) toxicity and host immunity in rats bearing Ward colon tumour. Cipro abolished chemotherapy-related mortality, which was 45% in animals that were not treated with Cipro. Although Cipro reduced body weight loss and muscle wasting, it was unable to prevent severe late-onset diarrhoea. Seven days after CPT-11, splenocytes were unable to proliferate (stimulation index=0.10+/-0.02) and produce proliferative and inflammatory cytokines (i.e., Interleukin (IL)-2, interferon-gamma (IFN-gamma), tumour necrosis factor-alpha (TNF-alpha) IL-1beta, IL-6) on mitogen stimulation in vitro (P<0.05 vs controls), whereas mesenteric lymph node (MLN) cells showed a hyper-proliferative response and a hyper-production of pro-inflammatory cytokines on mitogen stimulation. This suggests compartmentalised effects by CPT-11 chemotherapy on systemic and intestinal immunity. Cipro normalised the hyper-responsiveness of MLN cells, and in the spleen, it partially restored the proliferative response and normalised depressed production of IL-1beta and IL-6. Taken together, Cipro prevented infectious challenges associated with immune hypo-responsiveness in systemic immune compartments, and it may also alleviate excessive pro-inflammatory responses mediating local gut injury.

    Many people diagnosed with cancer will receive chemotherapy as a core component of their care. Recent changes in the delivery of cancer services mean that patients frequently receive care on an out-patient basis and are therefore often required to manage related side effects at home without direct support from oncology health professionals. The use of information and communications technology may be seen as a means of supporting patients receiving chemotherapy in the home care setting. This mixed methods study, reports on the perceptions of nurses (n=35) who participated in a randomised controlled trial of a mobile phone based, Advanced Symptom Management System (ASyMS), in the management of chemotherapy-related toxicity in patients with breast, lung and colorectal cancer. Nurses' perceptions of ASyMS were evaluated at the start and the end of the study. Overall, they could see the benefits of ASyMS in the remote monitoring of chemotherapy toxicity and its role in facilitating early intervention and subsequent management, demonstrating the potential utility of the system within clinical practice.

    Chemotherapy is the current mainstay of treatment for patients with newly diagnosed metastatic nasopharyngeal carcinoma (NPC), whereas the role of locoregional radiotherapy remains to be defined. In this study, we retrospectively evaluated the outcome of systemic chemotherapy followed by locoregional definitive intensity-modulated radiation therapy (IMRT) as first-line treatment for these patients. Forty-one patients with pathologically confirmed NPC with distant metastasis at initial diagnosis seen between March 2005 and February 2014 were included. All the patients were treated with platinum-based systemic chemotherapy followed by definitive IMRT to the primary head and neck region with or without concurrent chemotherapy. In addition, local treatment to metastatic lesions was given in 19 patients. With a median follow-up time of 25 months, 24 patients had died, and the estimated median overall survival time was 31.2 months. The 1-, 2-, 3- and 5-year estimated OS rates were 89.9, 67.4, 41.1 and 22.5%, respectively. Prognostic analyses showed that serum lactate dehydrogenase level (P = 0.021) and number of metastatic sites (single vs. multiple; P = 0.016) were significant prognostic factors. Five patients are still alive without evidence of disease after 52 to >101 months. All of them had a single metastatic lesion and received local treatment to metastatic sites. These results suggest that the use of definitive IMRT to treat the locoregional tumor in combination with systemic chemotherapy may prolong survival in patients with newly diagnosed metastatic NPC, making curability a possible consideration in selected patients with single metastasis. Further prospective clinical trials are warranted.

    Glioblastoma is a malignant brain tumor originating in the central nervous system. Successfully therapy of this disease required the efficient delivery of therapeutic agents to the tumor cells and tissues. Delivery of anticancer drugs using novel nanocarriers is promising in glioma treatment. Polymeric nanoparticles (PNPs), solid lipid nanoparticles (SLNs), and nanostructured lipid carriers (NLCs) were constructed for the delivery of temozolomide (TMZ). The anti-tumor effects of the three kinds of nanocarriers were compared to provide the optimum choice for gliomatosis cerebri treatment. TMZ-loaded PNPs (T-PNPs), SLNs (T-SLNs), and NLCs (T-NLCs) were formulated. Their particle size, zeta potential, drug encapsulation efficiency (EE), and drug loading (DL) capacity were evaluated. Anti-tumor efficacies of the three kinds of nanocarriers were evaluated on U87 malignant glioma cells (U87 MG cells) and mice-bearing malignant glioma model. T-NLCs displayed the best anti-tumor activity than other formulations in vivo and in vitro. The most significantly glioma inhibition was observed on NLCs formulations than PNPs and SLNs. This work demonstrates that NLCs can deliver TMZ into U87MG cells more efficiently, with higher inhibition efficacy than PNPs and SLNs. T-NLCs could be an excellent drug delivery system for glioblastoma chemotherapy.

    The standard regimen of systemic chemotherapy for patients with advanced urothelial cancer (UC) changed from methotrexate, vinblastine, adriamycin, and cisplatin (MVAC) to gemcitabine and cisplatin (GC) in 2008 when the use of gemcitabine for UC began to be reimbursed by public health insurance in Japan. We examined its influence on the chemotherapy trend in elderly patients aged ≥80 years. Among 345 patients included in our previous multicenter retrospective cohort study (chemotherapy for urothelial carcinoma: renal function and efficacy study; CURE study), the outcome of 30 patients aged ≥80 years was reviewed before and after 2008 and compared with 315 young patients. There were only 7 (4.6 %) elderly individuals among all registered patients before 2008, whereas the number increased to 23 (12 %) after 2008. Before 2008, only one elderly patient received MVAC, while GC (whose rate was similar to the rate in young patients) was administered to 13 patients (56.5 %) after 2008. The chemotherapeutic effect and overall survival (OS) rate was not significantly different between young and elderly patients. In the elderly treated with the GC regimen, the renal impairment rate after the first cycle was significantly higher, and the presence of distant metastases and renal impairment were independent prognostic factors in a multivariate analysis. Since GC was approved as the standard regimen for first-line chemotherapy in UC, selected elderly patients have been able to safely receive systemic chemotherapy like young patients. The clinical response rate and OS rate were similar to the young, but we need to monitor changes in renal function more closely in the elderly treated with GC.

    Children and adolescents with Burkitt Lymphoma (BL) and combined central nervous system (CNS) and bone marrow involvement still have a poor prognosis with chemotherapy alone. We therefore investigated in children and adolescents with bone marrow (≥25% blasts) and/or CNS-positive Burkitt lymphoma the chemoimmunotherapy combination of rituximab (375 mg/m(2) ) and the standard chemotherapy arm of our previously reported French-American-British (FAB) Lymphome Malins de Burkitt (LMB) 96 trial. Central pathological and cytogenetic characterization was also performed. There were 40 evaluable patients with Burkitt histology (25 with leukaemia and 15 with CNS disease ± leukaemia). The chemoimmunotherapy regimen was well tolerated. The incidence of grade III/IV mucositis during induction cycles with combined chemotherapy and rituximab was 31% and 26%, respectively. The 3-year event-free survival (EFS)/overall survival (OS) was 90% (95% confidence interval [CI], 76-96%) in the entire cohort and 93% (95% CI, 61-99%) in patients with CNS disease. Based on the results of this trial, an international randomized study of FAB/LMB 96 chemotherapy ± rituximab for high-risk patients is currently under investigation.

    Chemotherapy forms a core component of treatment for the majority patients with cancer. Recent changes in cancer services mean patients frequently receive such treatment as outpatients and are often required to manage side effects at home without direct support from oncology health professionals. Information technology continues to develop to support patients in the community; this study evaluated the impact of a mobile phone-based advanced symptom management system (ASyMS) on chemotherapy related toxicity in patients with lung, breast or colorectal cancer. One hundred and twelve patients were randomized from seven clinical sites across the UK; 56 patients used the mobile phone to record their symptoms, sending their reports directly to the nurses at their clinical site; 56 control group patients received standard care. Health professionals were alerted about any severe or life-threatening symptoms through the development of a chemotherapy symptom risk model. Patients' perceptions of ASyMS were evaluated pre and post participation. Patients reported many benefits of using ASyMS including improved communication with health professionals, improvements in the management of their symptoms, and feeling reassured their symptoms were being monitored while at home. ASyMS has the potential to positively impact on the management of symptoms in patients receiving chemotherapy treatment.

    Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side effect of many antineoplastic agents, but the mechanisms underlying the toxicities of certain drugs are unclear. At their maximal tolerated doses (MTD), the microtubule-binding drugs paclitaxel and ixabepilone induce more severe neuropathy in mice relative to eribulin mesylate, paralleling their toxicity profiles in clinic. We hypothesized that the severity of their neurotoxic effects might be explained by the levels at which they accumulate in the peripheral nervous system. To test this hypothesis, we compared their pharmacokinetics and distribution in peripheral nerve tissue. After administration of a single intravenous dose, each drug was rapidly cleared from plasma but all persisted in the dorsal root ganglia (DRG) and sciatic nerve (SN) for up to 72 hours. Focusing on paclitaxel and eribulin, we performed a two week MTD-dosing regimen followed by a determination of drug pharmacokinetics, tissue distribution and multiple functional measures of peripheral nerve toxicity for four weeks. Consistent with the acute dosing study, both drugs persisted in peripheral nervous tissues for weeks, in contrast to their rapid clearance from plasma. Notably, although eribulin exhibited greater DRG and SN penetration than paclitaxel, the neurotoxicity produced biologically was consistently more severe with paclitaxel. Overall, our results argued that sustained exposure of microtubule-binding chemotherapeutic agents in peripheral nerve tissues cannot by itself account for their associated neurotoxicity.

    Central nervous system (CNS) events are frequently reported among patients with advanced prostate cancer as a consequence of the treatments used in this patient population. To assess the incidence of CNS events in patients with advanced prostate cancer who initiated treatment with abiraterone acetate, bicalutamide, enzalutamide, or chemotherapy. The Truven Health MarketScan Research databases were used to retrospectively identify patients with prostate cancer who initiated treatment with abiraterone acetate, enzalutamide, bicalutamide, or chemotherapy after September 1, 2012 (ie, the index date). The chemotherapy agents included cabazitaxel, docetaxel, mitoxantrone hydrochloride, and estramustine, and were used as monotherapy or as combination therapy. Patients were followed until December 31, 2014, the end of exposure to treatment, or until loss to follow-up. Kaplan-Meier rates and adjusted Cox proportional hazard models were used to compare the incidence of CNS events between the abiraterone acetate cohort and the other cohorts. A sensitivity analysis of patients with a diagnosis of metastasis was also conducted. A total of 1067 patients receiving abiraterone acetate, 5524 receiving bicalutamide, 592 receiving enzalutamide, and 256 receiving chemotherapy were identified. After 12 months, patients who received abiraterone acetate were less likely to have a CNS event than patients who received enzalutamide (39.5% vs 46.0%, respectively; P = .0036) or chemotherapy (39.5% vs 51.1%, respectively; P = .0277), and were more likely to have a CNS event than patients who received bicalutamide (39.5% vs 34.2%, respectively; P = .0397). After multivariate adjustment, at 12 months, patients who initiated abiraterone acetate treatment had 20% (P = .0388) reduction in the risk for a CNS event compared with patients who initiated enzalutamide; 8% (P = .3622) versus bicalutamide; and 27% (P = .0456) versus chemotherapy. The sensitivity analysis yielded similar results. The

    To determine the optimal use of chemotherapy in the neoadjuvant, adjuvant, and metastatic setting in patients with advanced urothelial cell carcinoma, a consensus conference was convened by the World Health Organization (WHO) and the Société Internationale d'Urologie (SIU) to critically review the published literature on chemotherapy for patients with locally advanced bladder cancer. This article reports the development of international guidelines for the treatment of patients with locally advanced bladder cancer with neoadjuvant and adjuvant chemotherapy. Bladder preservation is also discussed, as is chemotherapy for patients with metastatic urothelial cancer. The conference panel consisted of 10 medical oncologists and urologists from 3 continents who are experts in this field and who reviewed the English-language literature through October 2004. Relevant English-language literature was identified with the use of Medline; additional cited works not detected on the initial search regarding neoadjuvant chemotherapy, bladder preservation, adjuvant chemotherapy, and chemotherapy for patients with metastatic urothelial cancer were reviewed. Evidence-based recommendations for diagnosis and management of the disease were made with reference to a 4-point scale. Results of the authors' deliberations are presented as a consensus document. Meta-analysis of randomized trials on cisplatin-containing combination neoadjuvant chemotherapy revealed a 5% difference in favor of neoadjuvant chemotherapy. No randomized trials have yet compared survival with transurethral resection of bladder tumor alone versus cystectomy for the management of patients with muscle-invasive disease. Collaborative international adjuvant chemotherapy trials are needed to assist researchers in assessing the true value of adjuvant chemotherapy. Systemic cisplatin-based combination chemotherapy is the only current modality that has been shown in phase 3 trials to improve survival in responsive patients

    The efficacy of chemotherapeutic treatment of colorectal cancer is challenged by severe gastrointestinal side effects, which include nausea, vomiting, constipation, and diarrhea. These symptoms can persist long after the treatment has been ceased. An emerging concept is the ability of platinum-based drugs to stimulate immunity, which is in contrast to conventional chemotherapeutic agents that are immunosuppressive. Here, we review the immunomodulatory aspects of platinum-based anticancer chemotherapeutics and their impact on gastrointestinal innervation. Given the bidirectional communication between the enteric nervous system and gastrointestinal immune system; exploring the consequences of platinum-induced immunogenicity will facilitate better understanding of gut dysfunction caused by chemotherapeutic agents. We propose that the development of future successful chemotherapeutics should rely on targeting the mechanisms underlying long-term gastrointestinal side effects.

    Quercetin belongs to the chemical class of flavonoids and can be found in many common foods, such as apples, nuts, berries, etc. It has been demonstrated that quercetin has a wide array of biological effects that are considered beneficial to health treatment, mainly as anticancer. However, therapeutic applications of quercetin have been restricted to oral administration due to its sparing solubility in water and instability in physiological medium. A drug delivery methodology was proposed in this work to study a new quercetin release system in the form of magnetite-quercetin-copolymer (MQC). These materials were characterized through XRD, TEM, IR, and Thermal analysis. In addition, the magnetization curves and quercetin releasing experiments were performed. It was observed a nanoparticle average diameter of 11.5 and 32.5 nm at Fe3O4 and MQC, respectively. The presence of magnetic nanoparticles in this system offers the promise of targeting specific organs within the body. These results indicate the great potential for future applications of the MQC to be used as a new quercetin release system.

    A 67-year-old man visited an urological clinic with a chief complaint of urination pain. Cystourethroscopy and magnetic resonance imaging (MRI) examination revealed a bladder tumor (cT3bN0M0). Marked leukocytosis and respiratory distress with pleural effusion appeared. Pulse steroid therapy improved the general condition partially. The patient was sent to our hospital for further examination. Serum granulocyte colony-stimulating factor (G-CSF) and interleukin-6 (IL-6) were high and the pathological findings of bladder tumor obtained by transurethral resection (TUR) revealed an urothelial carcinoma that produced G-CSF and IL-6. Neoadjuvant systemic chemotherapy was performed along with use of steroid and sivelestat, which ameliorated the respiratory distress. After three courses of systemic chemotherapy, serum G-CSF and IL-6 normalized and cystoprostatectomy was performed. The patient has been in good health at 20 months after the surgery with no evidence of recurrence.

    Aquaculture activities are increasing worldwide, stimulated by the progressive reduction of natural fish stocks in the oceans. However, these activities also suffer heavy production and financial losses resulting from fish infections caused by microbial pathogens, including multidrug resistant bacteria. Therefore, strategies to control fish infections are urgently needed, in order to make aquaculture industry more sustainable. Antimicrobial photodynamic therapy (aPDT) has emerged as an alternative to treat diseases and prevent the development of antibiotic resistance by pathogenic bacteria. The aim of this work was to evaluate the applicability of aPDT to inactivate pathogenic fish bacteria. To reach this objective a cationic porphyrin Tri-Py(+)-Me-PF was tested against nine pathogenic bacteria isolated from a semi-intensive aquaculture system and against the cultivable bacteria of the aquaculture system. The ecological impact of aPDT in the aquatic environment was also tested on the natural bacterial community, using the overall bacterial community structure and the cultivable bacteria as indicators. Photodynamic inactivation of bacterial isolates and of cultivable bacteria was assessed counting the number of colonies. The impact of aPDT in the overall bacterial community structure of the aquaculture water was evaluated by denaturing gel gradient electrophoresis (DGGE). The results showed that, in the presence of Tri-Py(+)-Me-PF, the growth of bacterial isolates was inhibited, resulting in a decrease of ≈7-8 log after 60-270 min of irradiation. Cultivable bacteria were also considerably affected, showing decreases up to the detection limit (≈2 log decrease on cell survival), but the inactivation rate varied significantly with the sampling period. The DGGE fingerprint analyses revealed changes in the bacterial community structure caused by the combination of aPDT and light. The results indicate that aPDT can be regarded as a new approach to control fish

    The aim of our meta-analysis is to assess the efficacy and safety of the target combined chemotherapy for the patients with unresectable advanced or recurrent gastric cancer. In accordance with the standard meta-analysis procedures, the patients included in our study were with unresectable advanced or recurrent gastric cancer and allocated randomly to receive target combined chemotherapy or the traditional chemotherapy. The search was applied to PubMed, EMBASE, Science Citation Index Expanded, Cocran's library (from inception to February 2016). All analyses were performed by STATA 12.0, with the odds ratio, hazard ratio, and 95 % confidence interval as the effect measures. Fourteen studies were included in this meta-analysis. A total of 5067 patients with advanced gastric cancer were divided into two arms: traditional chemotherapy arm and target combined chemotherapy arm. A significant improvement for overall survival (hazard ratio was 0.89, 95 % confidence interval: 0.83-0.95) and overall response rate (odds ratio was 1.44, 95 % confidence interval: 1.15-1.81) was observed, but no significant difference was found for progression-free survival (hazard ratio was 0.89, 95 % confidence interval: 0.77-1.00) in the target combined chemotherapy arm. In subgroup analysis, increasing benefits regarding overall survival and progression-free survival were found in anti epidermal growth factor receptor target drugs for selected patients subgroup and anti vascular endothelial growth factor receptor target drugs for unselected patients subgroup, but not in anti epidermal growth factor receptor target drugs for unselected patients subgroup. Besides, some adverse events were increased in the target combined chemotherapy arm. The target combined chemotherapy represented a better overall survival benefit and treatment efficiency and higher incidence of some grade 3-4 adverse events than the traditional chemotherapy for patients with unresectable advanced or recurrence gastric

    Because of the aggressive and recurrent nature of cancers, repeated and multimodal treatments are often necessary. Traditional cancer therapies have a risk of serious toxicity and side effects. Hence, it is crucial to develop an alternative treatment modality that is minimally invasive, effectively treats cancers with low toxicity, and can be repeated as required. We developed a light-activatable microneedle (MN) system that can repeatedly and simultaneously provide photothermal therapy and chemotherapy to superficial tumors and exert synergistic anticancer effects. This system consists of embeddable polycaprolactone MNs containing a photosensitive nanomaterial (lanthanum hexaboride) and an anticancer drug (doxorubicin; DOX), and a dissolvable poly(vinyl alcohol)/polyvinylpyrrolidone supporting array patch. Because of this supporting array, the MNs can be completely inserted into the skin and embedded within the target tissue for locoregional cancer treatment. When exposed to near-infrared light, the embedded MN array uniformly heats the target tissue to induce a large thermal ablation area and then melts at 50 °C to release DOX in a broad area, thus destroying tumors. This light-activated heating and releasing behavior can be precisely controlled and switched on and off on demand for several cycles. We demonstrated that the MN-mediated synergistic therapy completely eradicated 4T1 tumors within 1 week after a single application of the MN and three cycles of laser treatment. No tumor recurrence and no significant body weight loss of mice were observed. Thus, the developed light-activatable MN with a unique embeddable feature offers an effective, user-friendly, and low-toxicity option for patients requiring long-term and multiple cancer treatments.

    Clinical schedules drive resource utilization, cost, and patient wait time. Accurate appointment duration allocation ensures appropriate staffing ratios to daily caseloads and maximizes scarce resources. Dana-Farber Cancer Institute (DFCI) infusion appointment duration is adjusted by regimen using a consensus method of experts including pharmacists, nurses, and administrators. Using real-time location system (RTLS), we examined the accuracy of observed appointment duration compared with the scheduled duration. Appointment duration was calculated using RTLS at DFCI between August 1, 2013, and September 30, 2013. Duration was defined as the total time a patient occupied an infusion chair. The top 10 administered infusion regimens were investigated (n = 805). Median observed appointment durations were statistically different than the scheduled durations. Appointment durations were shorter than scheduled 98% (C), 95% (I), and 75% (F) of the time and longer than scheduled 77% (A) and 76% (G) of the time. Fifty-six percent of the longer than scheduled (A) appointments were at least 30 minute longer. RTLS provides reliable and unbiased data to improve schedule accuracy. Replacing consensus with system-based data may improve clinic flow, relieve staff stress, and increase patient satisfaction. Further investigation is warranted to elucidate factors that impact variation in appointment duration.

    The research conducted by Fister & Panetta shown an optimal control model of bone marrow cells against Cell Cycle Specific chemotherapy drugs. The model used was a bilinear system model. Fister & Panetta research has proved existence, uniqueness, and characteristics of optimal control (the chemotherapy effect). However, by using this model, the amount of bone marrow at the final time could achieve less than 50 percent from the amount of bone marrow before given treatment. This could harm patients because the lack of bone marrow cells made the number of leukocytes declining and patients will experience leukemia. This research would examine the optimal control of a bilinear system that applied to fixed final state. It will be used to determine the length of optimal time in administering chemotherapy and kept bone marrow cells on the allowed level at the same time. Before simulation conducted, this paper shows that the system could be controlled by using a theory of Lie Algebra. Afterward, it shows the characteristics of optimal control. Based on the simulation, it indicates that strong chemotherapy drug given in a short time frame is the most optimal condition to keep bone marrow cells spine on the allowed level but still could put playing an effective treatment. It gives preference of the weight of treatment for keeping bone marrow cells. The result of chemotherapy’s effect (u) is not able to reach the maximum value. On the other words, it needs to make adjustments of medicine’s dosage to satisfy the final treatment condition e.g. the number of bone marrow cells should be at the allowed level.

    Prolongation of survival of patients with small cell carcinoma of the lung with current effective systemic therapy has been accompanied by a marked increase in the frequency of relapse in the central nervous system (CNS). Prophylactic cranial irradiation (PCI) was shown to reduce the frequency of brain metastasis, but there was no increased short-term survival. Therefore, the necessity for PCI early in the course of treatment has been questioned, especially for patients with extensive disease. From January 1974 through March 1982, 205 patients with small cell carcinoma of the lung were treated at the Medical College of Wisconsin Affiliated Hospitals. None had clinical, radioisotopic, or computed tomographic evidence of brain metastasis. Eighty-two patients received radiotherapy and chemotherapy, but no PCI; 123 patients received combination chemotherapy and radiation therapy with PCI. The cumulative probability of brain metastasis without PCI was 36% at 12 months and 47% at 24 months; the probabilities were 6 and 10%, respectively with PCI. The 24-month probability of brain metastasis in patients with limited disease and no PCI was 45%; for those with extensive disease, it was 47%. No patient presented with extracranial central nervous system (ECNS) metastasis and no one without PCI developed it. Twelve patients who received PCI developed ECNS metastasis; the cumulative probabilities rose to 14% at 12 months and 22% at 24 months. The increased frequency of ECNS involvement has led to a phase I trial of PCI followed by six cycles of combination chemotherapy, without maintenance chemotherapy, followed by irradiation of the chest and spinal cord for patients with complete response.

    Inhaled therapy for lung cancer is a local form of treatment. Currently inhaled non-specific cytotoxic agents have been evaluated as a future treatment for local disease control and distant metastasis control. There are few information regarding the influence of local transporters and gene expression of the respiratory epithelium to the absorption of administered drugs. In the current work we used adenoviral-type 5(dE1/E3) (Cytomegalovirus promoter) with human ABCA10 transgene (Ad-h-ABCA10) purchased from Vector Labs® in order to investigate whether gene therapy can be used as a pre-treatment to enhance the efficiency of inhaled cisplatin. We included the following groups to our work: a) control, b) aerosol vector, c) aerosol vector plus cisplatin, d) aerosol cisplatin, e) intratumoral cisplatin administration, f) intratumoral vector plus cisplatin administration. The results indicate that the aerosol cisplatin group had a long term survival with the intratumoral cisplatin group following. The enhancement of the ABCA family locally to the respiratory system prior to the aerosol cisplatin administration can be used safely and efficiently. Future treatment design of local therapies should include the investigation of local transporters and genes. PMID:24723977

    Aim. The aim of this comprehensive literature review was to address the question: Does photodynamic therapy (PDT) improve root canal disinfection through significant bacterial reduction in the root canal system? Methodology. A comprehensive narrative literature review was performed to compare PDT effect with sodium hypochlorite as the comparative classical irrigant. Two reviewers independently conducted literature searches using a combination of medical subject heading terms and key words to identify relevant studies comparing information found in 7 electronic databases from January 2000 to May 2015. A manual search was performed on bibliography of articles collected on electronic databases. Authors were contacted to ask for references of more research not detected on the prior electronic and manual searches. Results. The literature search provided 62 titles and abstracts, from which 29 studies were related directly to the search theme. Considering all publications, 14 (48%) showed PDT to be more efficient in antimicrobial outcome than NaOCl (0.5–6% concentration) used alone and 2 (7%) revealed similar effects between them. Toluidine blue and methylene blue are the most used photosensitizers and most commonly laser has 660 nm of wavelength with a 400 nm diameter of intracanal fiber. Conclusions. PDT has been used without a well-defined protocol and still remains at an experimental stage waiting for further optimization. The level of evidence available in clinical studies to answer this question is low and at high risk of bias. PMID:26783392

    Surgery for colorectal liver metastases results in an overall survival of about 40% at 5 years. Progression-free survival is increased with the addition of oxaliplatin and fluorouracil chemotherapy. The addition of cetuximab to these chemotherapy regimens results in an overall survival advantage in patients with advanced disease who have the KRAS exon 2 wild-type tumour genotype. We aimed to assess the benefit of addition of cetuximab to standard chemotherapy in patients with resectable colorectal liver metastasis. Patients with KRAS exon 2 wild-type resectable or suboptimally resectable colorectal liver metastases were randomised in a 1:1 ratio to receive chemotherapy with or without cetuximab before and after liver resection. Randomisation was done using minimisation with factors of surgical centre, poor prognostic tumour (one or more of: ≥ 4 metastases, N2 disease, or poor differentiation of primary tumour), and previous adjuvant treatment with oxaliplatin. Chemotherapy consisted of oxaliplatin 85 mg/m(2) intravenously over 2 h and fluorouracil bolus 400 mg/m(2) intravenously over 5 min, followed by a 46 h infusion of fluorouracil 2400 mg/m(2) repeated every 2 weeks (regimen one) or oxaliplatin 130 mg/m(2) intravenously over 2 h and oral capecitabine 1000 mg/m(2) twice daily on days 1-14 repeated every 3 weeks (regimen two). Patients who had received adjuvant oxaliplatin could receive irinotecan 180 mg/m(2) intravenously over 30 min with fluorouracil instead of oxaliplatin (regimen three). Cetuximab was given as an intravenous dose of 500 mg/m(2) every 2 weeks with regimen one and three or a loading dose of 400 mg/m(2) followed by a weekly infusion of 250 mg/m(2) with regimen two. The primary endpoint was progression-free survival. This is an interim analysis, up to Nov 1, 2012, when the trial was closed, having met protocol-defined futility criteria. This trial is registered, ISRCTN22944367. 128 KRAS exon 2 wild-type patients were randomised to chemotherapy

    Purpose: To assess the efficacy and toxicity of chemotherapy consisting of cyclophosphamide, doxorubicin (Adriamycin), vincristine, and dexamethasone (CHOD) plus bis-chloronitrosourea (BCNU), cytosine arabinoside, and methotrexate (BVAM) followed by whole-brain irradiation (WBRT) for patients with primary central nervous system lymphoma (PCNSL). Methods and Materials: Patients 70 years old and younger with newly diagnosed, biopsy-proven PCNSL received one cycle of CHOD followed by two cycles of BVAM. Patients then received WBRT, 30.6 Gy, if a complete response was evoked, or 50.4 Gy if the response was less than complete; both doses were given in 1.8-Gy daily fractions. The primary efficacy endpoint was 1-year survival. Results: Thirty-six patients (19 men, 17 women) enrolled between 1995 and 2000. Median age was 60.5 years (range, 34 to 69 years). Thirty (83%) patients had baseline Eastern Cooperative Oncology Group performance scores of 0 to 1. All 36 patients were eligible for survival and response evaluations. Median time to progression was 12.3 months, and median survival was 18.5 months. The percentages of patients alive at 1, 2, and 3 years were 64%, 36%, and 33%, respectively. The best response was complete response in 10 patients and immediate progression in 7 patients. Ten (28%) patients had at least one grade 3 or higher neurologic toxicity. Conclusions: This regimen did improve the survival of PCNSL patients but also caused substantial toxicity. The improvement in survival is less than that reported with high-dose methotrexate-based therapies.

    Our understanding of the mitochondrial or intrinsic apoptosis pathway and its role in chemotherapy resistance has increased significantly in recent years by a combination of experimental studies and mathematical modelling. This combined approach enhanced the quantitative and kinetic understanding of apoptosis signal transduction, but also provided new insights that systems-emanating functions (i.e., functions that cannot be attributed to individual network components but that are instead established by multi-component interplay) are crucial determinants of cell fate decisions. Among these features are molecular thresholds, cooperative protein functions, feedback loops and functional redundancies that provide systems robustness, and signalling topologies that allow ultrasensitivity or switch-like responses. The successful development of kinetic systems models that recapitulate biological signal transduction observed in living cells have now led to the first translational studies, which have exploited and validated such models in a clinical context. Bottom-up strategies that use pathway models in combination with higher-level modelling at the tissue, organ and whole body-level therefore carry great potential to eventually deliver a new generation of systems-based diagnostic tools that may contribute to the development of personalised and predictive medicine approaches. Here we review major achievements in the systems biology of intrinsic apoptosis signalling, discuss challenges for further model development, perspectives for higher-level integration of apoptosis models and finally discuss requirements for the development of systems medical solutions in the coming years.

    Purpose: To evaluate the utility of an interventional CT system for intraarterial chemotherapy or chemoembolization for locally advanced and/or recurrent hepatic tumors.Methods: Thirty-eight patients with locally advanced or recurrent hepatic tumors underwent 73 intraarterial contrast-enhanced CT (IA-CECT) examinations immediately before chemotherapy or chemoembolization. The degree of tumor vascularity on angiography and enhancement on IA-CECT was classified into three grades: no, mild, or marked vascularity. The IA-CECT grades were compared with the angiographic grades.Results: Twenty-nine (69%) of 42 examinations that were interpreted as having no or mild vascularity on angiography were classified as marked enhancement on IA-CECT. Based on IA-CECT findings, the position of the catheter was changed in 14 (19%) of 73 CT examinations. The reasons for the reposition were as follows: weak or no enhancement of the tumor (n = 11) or strong enhancement of the gallbladder wall (n = 3). The treatment strategy was changed in three patients (8%). No major complications relating to the interventional procedures were observed.Conclusions: IA-CECT is a reliable method when evaluating the perfusion of the tumor and adjacent normal tissues. The interventional CT system is useful for performing safe and effective intraarterial chemotherapy or chemoembolization in patients with locally advanced and/or recurrent hepatic tumors.

    Numerous systemic treatment options exist for patients with mycosis fungoides (MF) and Sézary syndrome (SS), but no large comparative studies are published. To study the efficacy of treatments, a retrospective analysis of our cutaneous lymphoma database was undertaken, with 198 MF/SS patients undergoing systemic therapies. The primary end point was time to next treatment (TTNT). Patients with advanced-stage disease made up 53%. The median follow-up time from diagnosis for all alive patients was 4.9 years (range 0.3-39.6), with a median survival of 11.4 years. Patients received a median of 3 lines of therapy (range 1-13), resulting in 709 treatment episodes. Twenty-eight treatment modalities were analyzed. The median TTNT for single- or multiagent chemotherapy was only 3.9 months (95% confidence interval [CI] 3.2-5.1), with few durable remissions. α-interferon gave a median TTNT of 8.7 months (95% CI 6.0-18.0), and histone deacetylase inhibitors (HDACi) gave a median TTNT of 4.5 months (95% CI 4.0-6.1). When compared directly with chemotherapy, interferon and HDACi both had greater TTNT (P < .00001 and P = .01, respectively). This study confirms that all chemotherapy regimens assessed have very modest efficacy; we recommend their use be restricted until other options are exhausted. © 2015 by The American Society of Hematology.

    The Program in Evidence-Based Care (pebc) of Cancer Care Ontario recently created an evidence-based consensus guideline on the systemic treatment of early breast cancer. The evidence for the guideline was compiled using a systematic review to answer the question "What is the optimal systemic therapy for patients with early-stage, operable breast cancer, when patient and disease factors are considered?" The question was addressed in three parts: cytotoxic chemotherapy, endocrine treatment, and human epidermal growth factor receptor 2 (her2)-directed therapy. For the systematic review, the medline and embase databases were searched for the period January 2008 to May 2014. The Standards and Guidelines Evidence directory of cancer guidelines and the Web sites of major oncology guideline organizations were also searched. The basic search terms were "breast cancer" and "systemic therapy" (chemotherapy, endocrine therapy, targeted agents, ovarian suppression), and results were limited to randomized controlled trials (rcts), guidelines, systematic reviews, and meta-analyses. Several hundred documents that met the inclusion criteria were retrieved. The Early Breast Cancer Trialists' Collaborative Group meta-analyses encompassed many of the rcts found. Several additional studies that met the inclusion criteria were retained, as were other guidelines and systematic reviews. Chemotherapy was reviewed mainly in three classes: anti-metabolite-based regimens (for example, cyclophosphamide-methotrexate-5-fluorouracil), anthracyclines, and taxane-based regimens. In general, single-agent chemotherapy is not recommended for the adjuvant treatment of breast cancer in any patient population. Anthracycline-taxane-based polychemotherapy regimens are, overall, considered superior to earlier-generation regimens and have the most significant impact on patient survival outcomes. Regimens with varying anthracycline and taxane doses and schedules are options; in general, paclitaxel given every

    A monoclonal antibody targeted nanoscale drug delivery system (NDDS) for chemotherapy was evaluated in CD20-positive Raji cells in vitro. Nanoparticles were formed by the assembly of an amphiphilic polymer consisting of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-methoxypolyethyleneglycol-2000 (DSPE-PEG2000). Active carbon nanoparticles (ACNP) were conjugated to the chemotherapeutic agent, doxorubicin (DOX), and the nanoliposome carrier, DSPE-PEG2000 and DSPE-PEG2000-NH2 conjugated to the human anti-CD20 monoclonal antibody that targets B-lymphocytes. This monoclonal antibody targeted nanoparticle delivery system for chemotherapy formed the active NDDS complex, ACNP-DOX-DSPE-PEG2000-anti-CD20. This active NDDS was spherical in morphology and had good dispersion in the culture medium. When compared with the effects on CD20-negative YTS cells derived from natural killer/T-cell lymphoma, the active NDDS, ACNP-DOX-DSPE-PEG2000-anti-CD20, demonstrated DOX delivery to CD20-positive Raji cells derived from Burkitt's lymphoma (B cell lymphoma), resulting in increased cell killing in vitro. The intracellular targeting efficiency of the ACNP-DOX-DSPE-PEG2000-anti-CD20 complex was assessed by confocal laser microscopy and flow cytometry. The findings of this in vitro study have shown that the DSPE-PEG2000 polymeric liposome is an effective nanocarrier of both a monoclonal antibody and a chemotherapy agent and can be used to target chemotherapy to specific cells, in this case to CD20-positive B-cells. Future developments in this form of targeted therapy will depend on the development of monoclonal antibodies that are specific for malignant cells, including antibodies that can distinguish between lymphoma cells and normal lymphocyte subsets.

    Purpose: To update our institutional experience with neoadjuvant chemotherapy and minimized radiotherapy vs. radiation monotherapy for intracranial germinoma. Methods and Materials: We retrospectively reviewed records of 59 patients with diagnosis of primary intracranial germinoma between 1977 and 2007. Treatment was irradiation alone or neoadjuvant platinum-based chemotherapy and local irradiation (initial tumor plus margin) for patients with localized complete response and reduced-dose craniospinal irradiation for others. Results: For the chemoradiotherapy group (n = 28), median follow-up was 7 years. No patient died. The freedom from progression (FFP) rate was 88% at 5 years and 80% at 10 years. In 4 patients, disease recurred 1.1 to 6.8 years after diagnosis. All were young male patients who received 30.6 Gy to local fields after complete response to chemotherapy. The FFP rate was 88% for local irradiation vs. 100% for more extensive fields (p = .06). For the radiotherapy-alone group (n = 31), median follow-up was 15 years. Overall and disease-free survival rates were 93% and 93% at 5 years and 90% and 87% at 15 years. In 5 patients, disease recurred 1.1 to 4.9 years after diagnosis. Most patients in this group were young men 18 to 23 years of age with suprasellar primary disease treated with about 50 Gy to local fields. The FFP rate was 44% for local irradiation vs. 100% for more extensive fields (p < .01). Conclusions: The addition of neoadjuvant chemotherapy to local-field radiotherapy reduced central nervous system cancer recurrence when high-risk patients were excluded by thorough pretreatment staging. There was trend toward improved central nervous system tumor control when larger fields (whole brain, whole ventricle, or craniospinal axis) were used.

    Wisteria floribunda agglutinin-positive human Mac-2-binding protein (WFA(+)-M2BP) was developed recently as a predictive marker of progression to liver fibrosis and hepatocellular carcinoma (HCC) in patients seropositive for hepatitis C virus (HCV). We retrospectively analyzed 16 HCV-seropositive patients who received systemic chemotherapy for hematologic malignancies to evaluate the usefulness of WFA(+)-M2BP for predicting HCV-related complications. These were defined as the onset of significant liver damage (LD) with increased HCV RNA levels, leading to interrupted or discontinued chemotherapy or the occurrence of HCC after chemotherapy. Baseline WFA(+)-M2BP levels were determined using preserved serum samples. The median level of WFA(+)-M2BP was 1.59 [cutoff index (C.O.I.) value range 0.38-6.66]. With a median follow-up of 623 days (range 120-2404), LD and HCC were observed in three and two patients, respectively. Detectable HCV RNA and WFA(+)-M2BP ≥2.0 C.O.I. at baseline were identified as risk factors for these HCV-related complications (P = 0.034 and P = 0.005, respectively). The sensitivity, specificity, and positive and negative predictive values of the WFA(+)-M2BP level (cutoff point: 2.0 C.O.I.) for the occurrence of HCV-related complications were 100.0, 81.8, 71.4, and 100.0 %, respectively. WFA(+)-M2BP may be a useful marker for the prediction of HCV-related complications in HCV-seropositive patients following systemic chemotherapy.

    The whole brain radiotherapy (WBRT) dose for primary central nervous system lymphoma (PCNSL) patients who achieved complete response after induction chemotherapy was recently reduced to 23.4 Gy, but the optimal radiation dose for patients who achieved partial response (PR) is controversial. The aim of this study was to investigate the feasibility of reduced-dose WBRT for patients who achieved PR. We retrospectively reviewed the medical records of PCNSL patients who were treated with high-dose methotrexate based chemotherapy. We compared treatment outcomes between the patients who received WBRT at either 36 Gy or 45 Gy. The overall survival (OS) and intracranial progression-free survival (IC-PFS) was 66.3% and 42.6% at 5 years, respectively. There was no significant difference in treatment outcomes between the patients who received 36 Gy and 45 Gy, especially among patients who achieved PR. Three-year OS was 100% and 83.3% for 36 Gy and 45 Gy group, respectively (P = 0.313). Three-year IC-PFS was 60.0% and 66.7% for 36 Gy and 45 Gy group, respectively (P = 0.916). Findings of our study might provide a possibility for dose-reduction in patients achieving PR to induction chemotherapy, which may in turn reduce delayed neurologic sequelae. However, the number of patients included in this study was too small to lead to a concrete conclusion, thus further study is needed.

    This study was aimed to assess the feasibility and short-term outcomes of adjuvant systemic chemotherapy with either S-1/oxaliplatin (SOX) or mFOLFOX6 (FOLFOX)after curative resection of distant metastases from colorectal cancer. We retrospectively examined 16 patients who underwent R0 resection of colorectal metastases, including the liver (n=6), lung (n=5), lymph node (n=3), and peritoneum (n=2), followed by chemotherapy with SOX (n=7) or FOLFOX (n=9) until disease progression. The mean recurrence-free survival was 13.2 months in the SOX group and 16.9 months in the FOLFOX group. The mean overall survival was 17.9 and 22.9 months, respectively. The number of given courses were 6.5 and 11.0, respectively. Although sensory neuropathy was observed in 38% of the patients, relative dose intensity was higher than 80%. Adjuvant chemotherapy with SOX or FOLFOX was feasible and effective. Further randomized prospective trials are warranted to confirm these results.

    Invasive fungal infections (IFIs) is an important complication for acute myeloid leukemia (AML) patients receiving induction chemotherapy. However, the epidemiological information is not clear in Southeastern Asia, an area of potential high incidences of IFIs. To clarify it, we enrolled 298 non-M3 adult AML patients receiving induction chemotherapy without systemic anti-fungal prophylaxis from Jan 2004 to Dec 2009, when we applied a prospective diagnostic and treatment algorithm for IFIs. Their demographic parameters, IFI characters, and treatment outcome were collected for analysis. The median age of these patients was 51 years. Standard induction chemotherapy was used for 246 (82.6%) patients, and 66.8% of patients achieved complete remission (CR) or partial remission. The incidence of all-category IFIs was 34.6% (5.7% proven IFIs, 5.0% probable IFIs and 23.8% possible IFIs). Candida tropicalis was the leading pathogen among yeast, and lower respiratory tract was the most common site for IFIs (75.4%, 80/106). Standard induction chemotherapy and failure to CR were identified as risk factors for IFIs. The presence of IFI in induction independently predicted worse survival (hazard ratio 1.536 (1.100–2.141), p value = 0.012). Even in those who survived from the initial IFI insults after 3 months, the presence of IFIs in induction still predicted a poor long-term survival. This study confirms high incidences of IFIs in Southeastern Asia, and illustrates potential risk factors; poor short-term and long-term outcomes are also demonstrated. This epidemiological information will provide useful perspectives for anti-fungal prophylaxis and treatment for AML patients during induction, so that best chances of cure and survival can be provided.

    We report a case of advanced pancreatic cancer with liver and lung metastases that was well controlled over one year by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion in an outpatient setting. The patient was a 74-year-old woman. Chief complaints were back pain and anorexia. She was diagnosed with pancreas cancer with liver and lung metastases at the time of first visit. We started systemic chemotherapy with gemcitabine 1 g/body and 5-FU 1 g/body alternately every other week on an outpatient basis. At 1.5 months (M) after initiation of chemotherapy, we started radiation therapy to the main tumor at a total dose of 40 Gy. After radiation, chemotherapy was resumed. As a result, the size of the main tumor decreased but metastatic liver tumors got larger. Then we changed to combination therapy with systemic chemotherapy (gemcitabine and 5-FU) and hepatic arterial infusion (5-FU weekly). Liver metastases almost disappeared after 7.5 M. Despite all these treatments, however, the number of metastatic lung tumors increased. The patient was hospitalized for 15 M and died after 17 M. We focused on and succeeded in the prolongation of lifetime and maintenance of QOL by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion therapy.

    Chemotherapy stands today for cancer. In 1909, Paul Ehrlich (1854-1915) advocates the use of arsphenamine by infusion. So, he is considered as the father of chemotherapy. In fact, the first to have thought through chemotherapy was Sir Christopher Wren (1632-1723). In 1676, ideas and experiments on animals had sufficiently progressed to allow Michel Ettmuller (1644-1683) to publish the first edition of his book and several others were printed until 1753. In this book, he describes the first intravenous treatment, it sets the first indications, dosages and different products which can be used. However this method has been forgotten until the late 19th century.

    Background Updated practice guidelines on adjuvant chemotherapy for completely resected colon cancer are lacking. In 2008, Cancer Care Ontario’s Program in Evidence-Based Care developed a guideline on adjuvant therapy for stages ii and iii colon cancer. With newer regimens being assessed in this patient population and older agents being either abandoned because of non-effectiveness or replaced by agents that are more efficacious, a full update of the original guideline was undertaken. Methods Literature searches (January 1987 to August 2015) of medline, embase, and the Cochrane Library were conducted; in addition, abstracts from the American Society of Clinical Oncology, the European Society for Medical Oncology, and the European Cancer Congress were reviewed (the latter for January 2007 to August 2015). A practice guideline was drafted that was then scrutinized by internal and external reviewers whose comments were incorporated into the final guideline. Results Twenty-six unique reports of eighteen randomized controlled trials and thirteen unique reports of twelve meta-analyses or pooled analyses were included in the evidence base. The 5 recommendations developed included 3 for stage ii colon cancer and 2 for stage iii colon cancer. Conclusions Patients with completely resected stage iii colon cancer should be offered adjuvant 5-fluorouracil (5fu)–based chemotherapy with or without oxaliplatin (based on definitive data for improvements in survival and disease-free survival). Patients with resected stage ii colon cancer without “high-risk” features should not receive adjuvant chemotherapy. For patients with “high-risk” features, 5fu-based chemotherapy with or without oxaliplatin should be offered, although no clinical trials have been conducted to conclusively demonstrate the same benefits seen in stage iii colon cancer.

    Breast cancer is a heterogenous disease, comprised of at least 3 major subtypes: hormone receptor-positive/HER2-(HR+), HER2+, and HR-/HER2-(triple negative) breast cancers. The medical management of each subype is distinct. In this article, we review contemporary data supporting the use of chemotherapy, endocrine therapy and biologic therapies, especially HER2-directed agents, in the adjuvant and neoadjuvant setting in patients with newly diagnosed nonmetastatic (stage I-III) breast cancer.

    The purpose of this study is to evaluate the role of C-reactive protein (CRP) and ferritin blood levels in predicting the incidence of systemic infection among adult patients with acute myeloid leukemia (AML) treated with induction chemotherapy. Adult patients with newly diagnosed AML who were initially treated with conventional 3 + 7 induction chemotherapy within 5 days of their diagnosis were included. Patients with previous cytotoxic chemotherapy <3 years, acute promyelocytic leukemia diagnosis, human immunodeficiency virus infection, or significant systemic infection at the time of diagnosis were excluded. Patients were treated with an institutional policy of substantial identity with negligible differences regarding supportive care. Among 110 patients (median age 54.5 years), 39 infectious events in 38 patients were reported, along with 21 episodes of infectious treatment-related mortality (TRM; 19.1%). Elevated pre-treatment CRP (p = 0.032) and ferritin (p = 0.002) were related to the incidence of systemic infection. The degree of increase of blood CRP and ferritin level was correlated with the extent of leukocytosis. However, patients with elevated inflammatory markers above normal range had increased risk of infection irrespective of whether they had leukocytosis or not, suggesting that expansion of leukemic blast is another factor affecting the elevation of the markers independent to infection propensity and therefore the magnitude of the elevation does not quantitatively predict the risk of infection. Modest elevation of baseline blood inflammatory markers above the normal range could be an indicator for predicting the incidence of systemic infection in patients with AML.

    Background Gastrectomy with D2 lymphadenectomy is a standard procedure of curative resection for gastric cancer (GC). The aim of this study was to develop a simple and reliable prognostic scoring system for GC treated with D2 gastrectomy combined with adjuvant chemotherapy. Methods A prognostic scoring system was established based on clinical and laboratory data from 579 patients with localized GC without distant metastasis treated with D2 gastrectomy and adjuvant chemotherapy. Results From the multivariate model for overall survival (OS), five factors were selected for the scoring system: ≥50% metastatic lymph node rate, positive lymphovascular invasion, pathologic TNM Stage II or III, ≥5 ng/mL preoperative carcinoembryonic antigen level, and <110 g/L preoperative hemoglobin. Two models were derived using different methods. Model A identified low- and high-risk patients for OS (P<0.001), while Model B differentiated low-, intermediate-, and high-risk patients for OS (P<0.001). Stage III patients in the low-risk group had higher survival probabilities than Stage II patients. Both Model A (area under the curve [AUC]: 0.74, 95% confidence interval [CI]: 0.69–0.78) and Model B (AUC: 0.79, 95% CI: 0.72–0.83) were better predictors compared with the pathologic TNM classification (AUC: 0.62, 95% CI: 0.59–0.71, P<0.001). Adjuvant paclitaxel- or oxaliplatin-based or triple chemotherapy showed significantly better outcomes in patients classified as high risk, but not in those with low and intermediate risk. Conclusion A clinical three-tier prognostic risk scoring system was established to predict OS of GC treated with D2 gastrectomy and adjuvant chemotherapy. The potential advantage of this scoring system is that it can identify high-risk patients in Stage II or III who may benefit from paclitaxel- or oxaliplatin-based regimens. Prospective studies are needed to confirm these results before they are applied clinically. PMID:26966350

    Hepatic arterial infusion (HAI) chemotherapy is effective for treating primary and metastatic carcinoma of the liver. We compared the perfusion patterns of HAI chemotherapy on intra-arterial port-catheter computed tomography (iapc-CT) and fused images obtained with a combined single-photon emission computed tomography/computed tomography (SPECT/CT) system. We studied 28 patients with primary or metastatic carcinoma of the liver who bore an implantable HAI port system. All underwent abdominal SPECT using Tc-99m-MAA (185 Mbq); the injection rate was 1 mL/min, identical to the chemotherapy infusion rate, and 0.5 mL/sec for iapc-CT. Delivery was through an implantable port. We compared the intrahepatic perfusion (IHP) and extrahepatic perfusion (EHP) patterns of HAI chemotherapy on iapc-CT images and fused images obtained with a combined SPECT/CT system. In 23 of 28 patients (82%), IHP patterns on iapc-CT images and fused images were identical. In 5 of the 28 patients (18%), IHP on fusion images was different from IHP on iapc-CT images. EHP was seen on fused images in 12 of the 28 patients (43%) and on iapc-CT images in 8 patients (29%). In 17 patients (61%), upper gastrointestinal endoscopy revealed gastroduodenal mucosal lesions. EHP was revealed on fused images in 10 of these patients; 9 of them manifested gastroduodenal toxicity at the time of subsequent HAI chemotherapy. Fusion imaging using the combined SPECT/CT system reflects the actual distribution of the infused anticancer agent. This information is valuable not only for monitoring adequate drug distribution but also for avoiding potential extrahepatic complications.

  6. Chemotherapy for intraperitoneal use: a review of hyperthermic intraperitoneal chemotherapy and early post-operative intraperitoneal chemotherapy

    Peritoneal spread of tumors is a major problem in cancer management. Patients develop a marked deterioration in quality of life and shortened survival. This is in part due to bowel obstructions, marked ascites, and overall increase debilitation. Standard medical management has shown to be inadequate for the treatment of these problems. Surgery can palliate symptoms, however, it is unable to be complete at the microscopic level by a significant spillage of tumor cells throughout the abdomen. Chemotherapy can have some improvement in symptoms however it is short lived due to poor penetration into the peritoneal cavity. The role of intraperitoneal chemotherapy is to maximize tumor penetration and optimize cell death while minimizing systemic toxicity. Hyperthermic intraperitoneal chemotherapy (HIPEC) and early post-operative intraperitoneal chemotherapy (EPIC) are two treatment methods that serve this role and have been shown to improve survival. This review will discuss different chemotherapies used for both of these treatment options. PMID:26941983

    Background and Purpose Paclitaxel (PAC) is associated with chemotherapy-induced neuropathic pain (CIPN) that can lead to the cessation of treatment in cancer patients even in the absence of alternate therapies. We previously reported that chronic administration of the non-psychoactive cannabinoid cannabidiol (CBD) prevents PAC-induced mechanical and thermal sensitivity in mice. Hence, we sought to determine receptor mechanisms by which CBD inhibits CIPN and whether CBD negatively effects nervous system function or chemotherapy efficacy. Experimental Approach The ability of acute CBD pretreatment to prevent PAC-induced mechanical sensitivity was assessed, as was the effect of CBD on place conditioning and on an operant-conditioned learning and memory task. The potential interaction of CBD and PAC on breast cancer cell viability was determined using the MTT assay. Key Results PAC-induced mechanical sensitivity was prevented by administration of CBD (2.5 – 10 mg·kg−1) in female C57Bl/6 mice. This effect was reversed by co-administration of the 5-HT1A antagonist WAY 100635, but not the CB1 antagonist SR141716 or the CB2 antagonist SR144528. CBD produced no conditioned rewarding effects and did not affect conditioned learning and memory. Also, CBD + PAC combinations produce additive to synergistic inhibition of breast cancer cell viability. Conclusions and Implications Our data suggest that CBD is protective against PAC-induced neurotoxicity mediated in part by the 5-HT1A receptor system. Furthermore, CBD treatment was devoid of conditioned rewarding effects or cognitive impairment and did not attenuate PAC-induced inhibition of breast cancer cell viability. Hence, adjunct treatment with CBD during PAC chemotherapy may be safe and effective in the prevention or attenuation of CIPN. PMID:24117398

    S-1 has systemic activity for locally advanced pancreatic cancer (LAPC). Here, the efficacy and safety of induction gemcitabine (GEM) and S-1 (GS) followed by chemoradiotherapy (CRT) and systemic chemotherapy using S-1 for LAPC were assessed. The treatment consisted of four cycles of induction GS (S-1 60, 80, or 100 mg/day based on body surface area for 14 days every 3 weeks plus GEM 1000 mg/m(2) on days 8 and 15), followed by S-1 (80, 100, or 120 mg/day based on body surface area on days 1-14 and 22-35) and concurrent radiotherapy (50.4 Gy in 28 fractions). Maintenance chemotherapy with S-1 was started 1-4 weeks after CRT until disease progression or unacceptable toxicity was observed. The primary endpoint was 1-year survival. A total of 30 patients with LAPC were enrolled. The median survival and progression-free survival were 21.3 and 12.7 months, respectively. Overall survival rates at 1, 2, 3, and 4 years were 73.3, 36.7, 23.3, and 16.7%, respectively. The median survival of 23 patients who received CRT was 22.9 months, with a 3-year survival rate of 30.4%. The two most common grade 3 or 4 adverse events during induction GS were neutropenia (63.3%) and biliary tract infection (20%). Toxicities during CRT or maintenance chemotherapy were generally mild. This regimen was feasible and highly active resulting in encouraging survival in patients with LAPC. Further investigations are warranted to elucidate the effectiveness of this treatment strategy in future studies. Clinical trials information: UMIN000006332.

    CNS germinomas have an excellent prognosis with radiation therapy alone. However, in children, volume and dose of CNS radiation are associated with neurocognitive and neuroendocrine sequelae. Our objective was to determine long-term outcomes of our cohort who received chemotherapy and reduced radiation. This retrospective cohort study analyzed treatment and outcome of intracranial germinoma patients consecutively treated at Sick Kids, Toronto, Canada, from January 2000 to December 2013. 24 children (13 male, 11 female; median age 13.36 years) were identified. Median follow up was 61 months (range 1-144 months). Tumor location was suprasellar (n = 9), bifocal (8), pineal (6), and basal ganglia (1). Three children showed dissemination on imaging. 2/24 had only elevated serum human chorionic gonadotropin, 3/24 only elevated lumbar cerebrospinal fluid (CSF) hCG, and 2/24 had both elevated serum and lumbar CSF hCG. 23/24 children completed treatment and received multi-agent chemotherapy followed by either ventricular radiation (2340-2400 cGy) (n = 9), ventricular radiation + boost (1600 cGy) (n = 8), whole brain (2340 cGy) (n = 3), focal (4000 cGy) (n = 2) or craniospinal radiation (2340 cGy) (n = 1). Five-year progression free and overall survival was 96 and 100 % respectively. 8/24 patients with ventricular radiation ± boost (2340/4000 cGy) displayed stable full scale intelligence quotient over a mean interval of 3 years following radiation, but showed declined processing speed. In this limited experience, excellent 5-year overall survival rates were achieved with chemotherapy followed by reduced whole ventricular radiation even if ventricular radiation was delivered without boost.

    After taxane and anthracycline failure, no standard chemotherapy regimen is established in metastatic breast cancer (MBC). Capecitabine and cisplatin (XP) combination shows promising results in gastrointestinal cancer, but there are relatively scarce data in MBC. We reviewed the clinical outcome of XP regimen in anthracycline and taxane resistant, heavily pretreated MBC patients. Between Jan. 2010 to Feb. 2016, 48 HER2 negative MBC patients who failed anthracycline and taxane based chemotherapy were enrolled. In 43.8% of patients, more than 4 regimens were administrated before XP. Thirty-four patients (70.8%) were hormone receptor (HR) positive MBC. Patients were treated with XP (capecitabine [2000mg/m2 per oral; day 1-14] plus cisplatin [60mg/m2 IV; day 1], every 3 weeks) regimen. Median progression-free survival (PFS) in total population was 4.33 months (range 1.1~33.57 months). HR positive patients showed trends for superior PFS compared to triple negative breast cancer (TNBC), without statistical significance (6.53 vs. 3.83 months, P = 0.168). In HR positive group, patients receiving 3 or less lines of chemotherapy showed superior PFS compared to others (10.1 vs. 3.0 months, P = 0.039). In multivariate analysis, HR positive patients receiving 3 or less lines of regimens still showed superior PFS (HR = 2.624, 95% CI; 1.071~6.43, P = 0.032). Most common toxicity was grade 3-4 neutropenia, without treatment-related deaths. XP combination regimen showed clinical benefit with tolerable toxicity in heavily pretreated patients, including HR positive patients. After anthracycline and taxane failure, early administration of XP regimen in selected patients may have improve clinical outcome in breast cancer.

    Primary central nervous system lymphoma (PCNSL) is an aggressive variant of diffuse large B-cell lymphoma (DLBCL) confined to the CNS. TP53 mutations (MUT-TP53) were investigated in the context of MIR34A/B/C- and DAPK promoter methylation status, and associated with clinical outcomes in PCNSL patients. In a total of 107 PCNSL patients clinical data were recorded, histopathology reassessed, and genetic and epigenetic aberrations of the p53-miR34-DAPK network studied. TP53 mutational status (exon 5-8), with structural classification of single nucleotide variations according to the IARC-TP53-Database, methylation status of MIR34A/B/C and DAPK, and p53-protein expression were assessed. The 57/107 (53.2 %) patients that were treated with combination chemotherapy +/- rituximab (CCT-treated) had a significantly better median overall survival (OS) (31.3 months) than patients treated with other regimens (high-dose methotrexate/whole brain radiation therapy, 6.0 months, or no therapy, 0.83 months), P < 0.0001. TP53 mutations were identified in 32/86 (37.2 %), among which 12 patients had hotspot/direct DNA contact mutations. CCT-treated patients with PCNSL harboring a hotspot/direct DNA contact MUT-TP53 (n = 9) had a significantly worse OS and progression free survival (PFS) compared to patients with non-hotspot/non-direct DNA contact MUT-TP53 or wild-type TP53 (median PFS 4.6 versus 18.2 or 45.7 months), P = 0.041 and P = 0.00076, respectively. Multivariate Cox regression analysis confirmed that hotspot/direct DNA contact MUT-TP53 was predictive of poor outcome in CCT-treated PCNSL patients, P = 0.012 and P = 0.008; HR: 1.86 and 1.95, for OS and PFS, respectively. MIR34A, MIR34B/C, and DAPK promoter methylation were detected in 53/93 (57.0 %), 80/84 (95.2 %), and 70/75 (93.3 %) of the PCNSL patients with no influence on survival. Combined MUT-TP53 and MIR34A methylation was associated with poor PFS (median 6.4 versus 38.0 months), P = 0

    Successful therapeutic interventions to prevent disease progression in patients with nonmetastatic osteosarcoma have included surgery with adjuvant chemotherapy. Presurgical chemotherapy has been advocated for these patients because of putative improvement in event-free survival (EFS). The advantages of presurgical chemotherapy include early administration of systemic chemotherapy, shrinkage of primary tumor, and pathologic identification of risk groups. The theoretic disadvantage is that it exposes a large tumor burden to marginally effective chemotherapy. The contribution of chemotherapy and surgery timing has not been tested rigorously. Between 1986 and 1993, we conducted a prospective trial in patients with nonmetastatic osteosarcoma who were assigned randomly to immediate surgery or presurgical chemotherapy. Except for the timing of surgery (week 0 or 10), patients received 44 weeks of identical combination chemotherapy that included high-dose methotrexate with leucovorin rescue, doxorubicin, cisplatin, bleomycin, cyclophosphamide, and dactinomycin. One hundred six patients were enrolled onto this study. Six were excluded from analysis. Of the remaining 100 patients, 45 were randomly assigned to immediate chemotherapy, and 55 were randomly assigned to immediate surgery. Sixty-seven patients remain disease-free. At 5 years, the projected EFS +/- SE is 65% +/- 6% (69% +/- 8% for immediate surgery and 61% +/- 8% for presurgical chemotherapy; P =.8). The treatment arms had similar incidence of limb salvage (55% for immediate surgery and 50% for presurgical chemotherapy). Chemotherapy was effective in both treatment groups. There was no advantage in EFS for patients given presurgical chemotherapy.

    Purpose: Avoidance radiotherapy or reduction of irradiation doses in patients with primary central nervous system lymphoma (PCNSL) in complete remission (CR) after high-dose methotrexate (HD-MTX)-based chemotherapy has been proposed to minimize the neurotoxicity risk. Nevertheless, no study has focused on the survival impact of radiation parameters, as far as we know, and the optimal radiation schedule remains to be defined. Methods and Materials: The impact on outcome and neurologic performance of different radiation fields and doses was assessed in 33 patients with PCNSL who achieved CR after MTX-containing chemotherapy and were referred to consolidation whole-brain irradiation (WBRT). Patterns of relapse were analyzed on computed tomography-guided treatment planning, and neurologic impairment was assessed by the Mini Mental Status Examination. Results: At a median follow-up of 50 months, 21 patients are relapse-free (5-year failure-free survival [FFS], 51%). WBRT doses {>=}40 Gy were not associated with improved disease control in comparison with a WBRT dose of 30 to 36 Gy (relapse rate, 46% vs. 30%; 5-year FFS, 51% vs. 50%; p = 0.26). Disease control was not significantly different between patients irradiated to the tumor bed with 45 to 54 Gy or with 36 to 44 Gy, with a 5-year FFS of 35% and 44% (p = 0.43), respectively. Twenty patients are alive (5-year overall survival, 54%); WB and tumor bed doses did not have an impact on survival. Impairment as assessed by the Mini Mental Status Examination was significantly more common in patients treated with a WBRT dose {>=}40 Gy. Conclusion: Consolidation with WBRT 36 Gy is advisable in patients with PCNSL in CR after HD-MTX-based chemotherapy. Higher doses do not change the outcome and could increase the risk of neurotoxicity.

    Background The aim of this study was to investigate the effects of surgical castration, particularly delaying the time to entrance of systemic chemotherapy, in castration-resistant prostate cancer (CRPC) patients who were refractory to initial combination androgen deprivation therapy. Materials and methods We analyzed the clinical data of 14 CRPC patients diagnosed at Seoul National University Bundang Hospital (SNUBH) from November 2008 through May 2015. After exclusion of three patients, we finally analyzed the baseline characteristics of 11 CRPC patients. We also assessed the delaying time of docetaxel administration, which was defined as response duration, after surgical castration. Results After bilateral orchiectomy, the treatment response rate was 45.4% and the median duration of response was 9 months (range 4–48 mo). Responders had less aggressive biopsy Gleason scores compared to nonresponders. Notably, responders showed the reducing pattern of serum prostate specific antigen levels, while nonresponders demonstrated increasing tendency after surgical castration. Moreover, responders also presented with a reduction pattern of serum testosterone levels, whereas nonresponders showed an increasing pattern of testosterone levels after bilateral orchiectomy. Conclusions In summary, despite the limited number of cases for convincing evidence, our results shed light again on the clinical benefits of surgical castration prior to the systemic chemotherapy in some CRPC patients after initial hormone therapy.

    Goblet cell carcinoid of the appendix is a rare neoplasm and clinically tends to take a malignant course. Most cases are young and early stage, and the surgical strategy is available. But appropriate chemotherapy for inoperable cases with peritoneal dissemination is not established. A 77-year-old woman with a past history of appendectomy was admitted to our hospital complaining of abdominal fullness. Abdominal computed tomography showed massive ascites and slight contrast enhancement of appendix. A tumor was found by colonoscopic examination at the orifice of vermiform and was diagnosed pathologically as goblet cell carcinoid of the appendix. Laparoscopy showed multiple peritoneal dissemination. We performed intraperitoneal paclitaxel(PTX)administration at 70 mg/m(2) week without any resection of the tumor. Ascites were reduced immediately, but drug-induced interstitial pneumonia occurred due to PTX. After steroid therapy, we switched to systemic S-1 therapy. For about one year, her tumor was controlled but became worse thirteen months after diagnosis and died. It is thought that intraabdominal paclitaxel administration and systemic S-1 therapy can be one of appropriate forms of chemotherapy for inoperable peritoneal carcinomatosis from goblet cell carcinoid of appendix.

    Serum lactate dehydrogenase (LDH) concentrations correlate with tumor progression and poor outcome. We evaluated the predictive value of serum LDH level for overall survival (OS) of patients with advanced pancreatic cancer after gemcitabine-based chemotherapy. We retrospectively enrolled 364 patients with locally advanced or metastatic pancreatic adenocarcinoma who were then allocated to training (n = 139) and validation cohorts (n = 225). We evaluated the association between serum LDH levels and OS as well as with markers of systemic inflammation, including neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and lymphocyte/monocyte ratio (LMR). Kaplan–Meier analyses revealed that low serum LDH levels in the training cohort significantly correlated with longer OS. Multivariate analysis identified the serum LDH levels as an independent prognostic predictor of OS (p = 0.005). Serum LDH levels correlated positively with NLR and PLR and correlated negatively with LMR. Similar results were obtained for the validation cohort, except that multivariate analysis identified the serum LDH level as a significant prognostic predictor and only a statistical trend for OS (p = 0.059). We conclude that serum LDH levels were associated with the systemic inflammatory response and served as a significant prognostic predictor of OS. Serum LDH levels predicted OS in patients with advanced pancreatic cancer after gemcitabine-based palliative chemotherapy. PMID:28345594

    AIM: In nonresectable cholangiocellular carcinoma (CCC) therapeutic options are limited. Recently, systemic chemotherapy has shown response rates of up to 30%. Additional regional therapy of the arterially hyper vascularized hepatic tumors might represent a rational approach in an attempt to further improve response and palliation. Hence, a protocol combining transarterial chemoembolization and systemic chemotherapy was applied in patients with CCC limited to the liver. METHODS: Eight patients (6 women, 2 men, mean age 62 years) with nonresectable CCC received systemic chemotherapy (gemcitabine 1000 mg/m2) and additional transarterial chemoembolization procedures (50 mg/m2 cisplatin, 50 mg/m2 doxorubicin, up to 600 mg degradable starch microspheres). Clinical follow-up of patients, tumor markers, CT and ultrasound were performed to evaluate maximum response and toxicity. RESULTS: Both systemic and regional therapies were tolerated well; no severe toxicity (WHO III/IV) was encountered. Nausea and fever were the most commonly observed side effects. A progressive rarefication of the intrahepatic arteries limited the maximum number of chemoembolization procedures in 4 patients. A median of 2 chemoembolization cycles (range, 1-3) and a median of 6.5 gemcitabine cycles (range, 4-11) were administered. Complete responses were not achieved. As maximum response, partial responses were achieved in 3 cases, stable diseases in 5 cases. Two patients died from progressive disease after 9 and 10 mo. Six patients are still alive. The current median survival is 12 mo (range, 9-18); the median time to tumor progression is 7 mo (range, 3-18). Seven patients suffered from tumor-related symptoms prior to therapy, 3 of these experienced a treatment-related clinical relief. In one patient the tumor became resectable under therapy and was successfully removed after 10 mo. CONCLUSION: The present results indicate that a combination of systemic gemcitabine therapy and repeated regional

    The authors investigated objective response rate to high dose methotrexate (HDMTX)-based combination chemotherapy in primary central nervous system lymphoma (PCNSL), and sought to identify factors that influence response to HDMTX-based combination therapy. Prospective observational analysis was performed on 52 PCNSL patients. All patients received HDMTX (3.5 g/m(2)) and vincristine (1.4 mg/m(2)/day) for one day during weeks 1, 3, 5, 7, and 9, and procarbazine (100 mg/m(2)/day) for one week during weeks 1, 5, and 9. Forty-one patients (78.8%) achieved complete or partial remission. Higher objective response rates were observed for patients with: 1) age < 60 yr; 2) Eastern Cooperative Oncology Group (ECOG) performance score of < 2; 3) low risk status as defined by the International Extranodal Lymphoma Study Group; 4) p53 positivity; 5) XBP-1 negativity; 6) MUM-1 negativity; and 7) homogenous gadolinium enhancement in MR images. Multivariate analysis showed that ECOG performance score of < 2, low risk, negativity for XBP-1, homogenous gadolinium enhancement by MRI, and response to chemotherapy were associated with longer overall survival. In particular, it is interesting to note that patients with a PCNSL that is homogeneously enhanced by gadolinium have a higher objective response rate, and a longer progression-free survival and overall survival.

    The purpose of this review is to familiarise radiologists with the spectrum of hepatic toxicity seen in the oncology setting, in view of the different systemic therapies used in cancer patients. Drug-induced liver injury can manifest in various forms, and anti-neoplastic agents are associated with different types of hepatotoxicity. Although chemotherapy-induced liver injury can present as hepatitis, steatosis, sinusoidal obstruction syndrome, and chronic parenchymal damages, molecular targeted therapy-associated liver toxicity ranges from mild liver function test elevation to fulminant life-threatening acute liver failure. The recent arrival of immune checkpoint inhibitors in oncology has introduced a new range of immune-related adverse events, with differing mechanisms of liver toxicity and varied imaging presentation of liver injury. High-dose chemotherapy regimens for haematopoietic stem cell transplantation are associated with sinusoidal obstruction syndrome. Management of hepatic toxicity depends on the clinical scenario, the drug in use, and the severity of the findings. In this article, we will (1) present the most common types of oncological drugs associated with hepatic toxicity and associated liver injuries; (2) illustrate imaging findings of hepatic toxicities and the possible differential diagnosis; and (3) provide a guide for management of these conditions.

    The prognosis for hepatocellular carcinoma with extrahepatic metastasis or vascular invasion is very poor. We treated a case successfully by combining chemotherapy and liver resection for hepatocellular carcinoma with multiple pulmonary metastases and vascular invasion. A 56-year-old man who complained of abdominal pain in his right side was transported to the hospital by ambulance. Because CT scan revealed the rupture of hepatocellular carcinoma, he underwent emergency transcatheter arterial embolization (TAE). A close examination revealed tumor thrombus in the inferior vena cava and posterior segment of the portal vein branch, with multiple pulmonary metastases. We conducted right hepatic lobectomy and removal of the inferior vena cava tumor thrombus. After the operation, pulmonary metastatic lesions gradually grew larger, so the oral administration of S-1 at 120 mg per day was started. At the end of the first course, the CT scan revealed that multiple pulmonary metastases were significantly reduced, and treatment was maintained until the end of 4 courses. A prolongation of survival could be expected by combining systemic chemotherapy and liver resection for advanced hepatocellular carcinoma such as the present case.

    Systemic chemotherapy given at maximum tolerated doses (MTD) has been the mainstay of cancer treatment for more than half a century. In some chemosensitive diseases such as hematologic malignancies and solid tumors, MTD has led to complete remission and even cure. The combination of maintenance therapy and standard MTD also can generate good disease control; however, resistance to chemotherapy and disease metastasis still remain major obstacles to successful cancer treatment in the majority of advanced tumors. Metronomic chemotherapy, defined as frequent administration of chemotherapeutic agents at a non-toxic dose without extended rest periods, was originally designed to overcome drug resistance by shifting the therapeutic target from tumor cells to tumor endothelial cells. Metronomic chemotherapy also exerts anti-tumor effects on the immune system (immunomodulation) and tumor cells. The goal of immunotherapy is to enhance host anti-tumor immunities. Adding immunomodulators such as metronomic chemotherapy to immunotherapy can improve the clinical outcomes in a synergistic manner. Here, we review the anti-tumor mechanisms of metronomic chemotherapy and the preliminary research addressing the combination of immunotherapy and metronomic chemotherapy for cancer treatment in animal models and in clinical setting.

    To investigate the value of the HCT-CI score in chemotherapy risk assessment and prognosis of elderly patients with acute myeloid leukemia (AML). The clinical data of 116 AML patients older than 60 years in the department of Hematology, Henan Provincial People's Hospital from January 2000 to December 2010 were analyzed retrospectively. All patients received cytarabine-based regimens, including protocol DA, MA, IA, AA or CAG, followed by cytarabine-based postremission treatment. (1) Comorbidities were evaluated by using HCT-CI score, the early death rates and median survival time were compared among these different groups. (2) These prognostic factors were analyzed by univariate and multivariate analyses. (1) All 116 cases were followed-up. The patient cohort was divided into those with HCT-CI scores of 0, 1 or 2, or ≥ 3. Early death rates were 3.7%, 12.1% and 23.21% in above three groups, respectively (P < 0.01). Overall survival were 345, 225 and 113 days, respectively (P < 0.01). (2) HCT-CI score ≥ 3 (P < 0.01), antecedent MDS history (P = 0.035), high-risk karyotype (P = 0.018), white blood cells at diagnosis ≥ 100×10(9)/L (P = 0.041) were independent adverse prognostic factors with multivariate analysis. (1) The HCT-CI score can objectively assess elderly AML patients with comorbidities and predict chemotherapy risk in older patients receiving AML induction therapy. (2) Antecedent MDS history, high-risk karyotype, high white blood cell, and HCT-CI score ≥ 3 are independent adverse prognostic factors of elderly AML patients.

    Few dermatologic conditions carry as much emotional distress as chemotherapy-induced hair loss. Forty-seven percent of female patients consider hair loss the most traumatic aspect of chemotherapy, and 8% would decline chemotherapy because of fear of hair loss. A number of agents have been evaluated on the basis of the current understanding of the underlying pathobiology. Among the agents that have been evaluated, topical minoxidil was able to reduce the severity or shorten the duration but could not prevent hair loss. The major approach to minimize chemotherapy-induced hair loss is by scalp cooling, although most published data on scalp cooling are of poor quality. Because chemotherapy-induced toxicity has been associated with nutritional status, nutritional assessment and support might confer beneficial effects. Several experimental approaches to the development of pharmacological agents are under evaluation including: anti-oxidants, cytokines and growth factors, cell cycle and proliferation modifiers, and inhibitors of apoptosis. At present, no approved pharmacologic treatment of chemotherapy-induced hair loss exists. The incidence and severity of the condition are variable and related to the particular chemotherapeutic protocol. Fortunately, chemotherapy-induced hair loss is mostly reversible, and appropriate hair and scalp care and temporarily wearing a wig may be the most effective coping strategy.

    Co-delivery of chemotherapy drugs and siRNA for cancer therapy has achieved remarkable results according to synergistic/combined antitumor effects, and is recognized as a promising therapeutic modality. However, little attention has been paid to the extremely complex mechanisms of chemotherapy drug-siRNA pairs during co-delivery process. Proper selection of chemotherapy drug-siRNA pairs is beneficial for achieving desirable cancer therapeutic effects. Exploring the inherent principles during chemotherapy drug-siRNA pair selection for co-delivery would greatly enhanced therapeutic efficiency. To achieve ideal results, this article will systematically review current different mechanism-based chemotherapy drug-siRNA pairs for co-delivery in cancer treatment. Large-scale library screening of recent different chemotherapy drug-siRNA pairs for co-delivery would help to establish the chemotherapy drug-siRNA pair selection principle, which could pave the way for co-delivery of chemotherapy drugs and siRNA for cancer treatment in clinic. Following the inherent principle of chemotherapy drug-siRNA pair, more effective co-delivery vectors can be designed in the future. Copyright © 2017 Elsevier B.V. All rights reserved.

  10. Chemotherapy in metastatic retinoblastoma.

    Eleven children with metastatic retinoblastoma diagnosed during the period 1970-1984 were treated with chemotherapy. Short-term complete responses were observed in three children treated with a four-drug combination which included cisplatinum, and in one child treated with vincristine and cyclophosphamide. The median duration of survival of the 11 children receiving chemotherapy was nine months, whilst the median survival of 13 children with metastatic retinoblastoma who were not given chemotherapy was only 2.3 months (p = 0.06). This suggests that retinoblastoma is a chemosensitive tumour and therefore adjuvant chemotherapy may have a role in children with retinoblastoma who at diagnosis are thought to be at high risk of developing metastatic disease.

    Treatment strategies for colorectal cancer (CRC) are highly variable. The aim of this study is to examine the patterns of chemotherapy and biologic therapy use for CRC patients in a national medical claims database. A retrospective and observational analysis was performed using the i3 Innovus claims database to identify healthcare services consumed by patients aged 18 years and older, diagnosed with CRC between 1 January 2005 and 30 June 2009 in commercial health plans. Of 9,876 subjects diagnosed with CRC, fluorouracil (23.5 %) and capecitabine (10.0 %) were the dominant first-line monotherapies, followed by bevacizumab (3.2 %) and oxaliplatin (2.9 %). The most common combination regimen at first line and first and second line was FOLFOX (fluorouracil, leucovorin, and oxaliplatin; more than 25 %). The combinations FOLFIRI (fluorouracil, leucovorin, and irinotecan) plus bevacizumab (14.2 %) and FOLFOX plus bevacizumab (13.9 %) were significantly more frequent in third and successive lines of CRC therapy than other regimens (χ(2) = 191.2; P < 0.01). Additionally, the average annualized cost of CRC treatment for all patients was $US66,452, and the adjusted analysis demonstrated that patients receiving FOLFOX-A (FOLFOX + avastin) or FOLFIRI-A (FOLFIRI + avastin) had higher costs for CRC treatment. With the exception of a sizeable portion of patients on monotherapy, the treatment patterns for CRC were largely consistent with National Comprehensive Cancer Network (NCCN) guidelines.

    The aims of this study were to investigate the outcomes of second salvage auto-SCT and to identify the impacts of a second auto-SCT compared with systemic chemotherapy alone on disease outcome. Data from 48 patients who underwent second auto-SCT were matched to 144 patients (1:3) who received systemic chemotherapy alone from the Korean Myeloma Registry. Groups were matched for nine potential prognostic factors and compared for treatment outcomes. The median age of matching-pairs at relapse was 55.5 years. A total of 156 patients (81%) received vincristine, doxorubicin and dexamethasone induction therapy before the first auto-SCT. Thirty-five patients (73%) in the second auto-SCT group received novel agent-based therapies before the second auto-SCT, and similar proportion in both groups received novel therapies after relapse of front-line auto-SCT. With a median follow-up of 55.3 months, patients who underwent a second auto-SCT had significantly better median OS (55.5 vs 25.4 months, P=0.035). In multivariate analysis for OS, <18 months time to progression after first auto-SCT, International Staging System III and salvage chemotherapy alone were independent predictors for worse OS. The outcomes of second auto-SCT appear to be superior to those of systemic chemotherapy alone. A randomized trial comparing both treatment strategies is required.

    In recent years, chemotherapy with caffeine has manifested potently high efficacy against osteosarcoma, although adverse effects have been observed. Recently, we developed a novel drug delivery system (DDS) with nonionic vesicles prepared from Span 80 which have promising physicochemical properties as an attractive possible alternative to commonly used liposomes. Herein, we demonstrated that tumor-specific caffeine-potentiated chemotherapy for murine osteosarcoma administered by a novel DDS with Span 80 nano-vesicles showed significant antitumor effects as well as limited adverse effects. The osteosarcoma cell line, LM8, was transplanted into C3H/HeJ mice which then were administered therapeutic agents. Ifosfamide (IFO) was employed as well as caffeine as an enhancer. Span 80 vesicles containing IFO and/or caffeine were freshly prepared. On days 0, 2 and 4, different combinations of the agents were administered to mice: IFO alone (direct i.v.), IFO vesicles (IV), IV+caffeine, IV+caffeine vesicles (CV), PBS alone vesicles (PV), and PBS alone as negative control (PBS i.v.). Then, the mice were sacrificed on day 7. Antitumor effects of the reagents were also analyzed in vitro. Moreover, fertility examination was performed. In vitro, a combination of IV+CV showed significant induction of apoptosis in the early phase. Tumor volumes in the IV+CV group were significantly reduced compared with the other groups. Histological analyses showed that the IV and IV+CV groups had significantly lower viable tumor areas. The IFO direct i.v. group showed a certain grade of renal injury as well as marked suppression of spermatogenesis, while the IV or IV+CV group showed no marked changes. The fertility test revealed that the male mice with IV+CV administration had normal fertility, and no malformations were detected in their progeny. This DDS model is of potential importance for clinical application in the therapy of metastatic osteosarcoma.

    In this study, we developed functionalized superparamagnetic iron oxide (SPIO) nanoparticles consisting of a magnetic Fe3O4 core and a shell of aqueous stable polyethylene glycol (PEG) conjugated with doxorubicin (Dox) (SPIO-PEG-D) for tumor magnetic resonance imaging (MRI) enhancement and chemotherapy. The size of SPIO nanoparticles was ~10 nm, which was visualized by transmission electron microscope. The hysteresis curve, generated with vibrating-sample magnetometer, showed that SPIO-PEG-D was superparamagnetic with an insignificant hysteresis. The transverse relaxivity (r 2) for SPIO-PEG-D was significantly higher than the longitudinal relaxivity (r 1) (r 2/r 1 >10). The half-life of Dox in blood circulation was prolonged by conjugating Dox on the surface of SPIO with PEG to reduce its degradation. The in vitro experiment showed that SPIO-PEG-D could cause DNA crosslink more serious, resulting in a lower DNA expression and a higher cell apoptosis for HT-29 cancer cells. The Prussian blue staining study showed that the tumors treated with SPIO-PEG-D under a magnetic field had a much higher intratumoral iron density than the tumors treated with SPIO-PEG-D alone. The in vivo MRI study showed that the T2-weighted signal enhancement was stronger for the group under a magnetic field, indicating that it had a better accumulation of SPIO-PEG-D in tumor tissues. In the anticancer efficiency study for SPIO-PEG-D, the results showed that there was a significantly smaller tumor size for the group with a magnetic field than the group without. The in vivo experiments also showed that this drug delivery system combined with a local magnetic field could reduce the side effects of cardiotoxicity and hepatotoxicity. The results showed that the developed SPIO-PEG-D nanoparticles own a great potential for MRI-monitoring magnet-enhancing tumor chemotherapy.

    Intravesical bacillus Calmette-Guerin (BCG) treatment is the most common therapy to prevent progression and recurrence of non-muscle invasive bladder cancer (NMIBC). Although the immunoreaction elicited by BCG treatment is well documented, those induced by intravesical treatment with chemotherapeutic agents are much less known. We investigated the immunological profiles caused by mitomycin C, gemcitabine, adriamycin and docetaxel in the N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN)-induced orthotopic bladder cancer mouse model. Ninety mice bearing orthotopic bladder cancer induced by BBN were randomly divided into six groups and treated with chemotherapeutic agents once a week for four weeks. After last treatment, bladder and serum samples were analyzed for cell surface and immunological markers (CD4, CD8, CD56, CD204, Foxp3, and PD-L1) using immunohistochemistry staining. Serum and urine cytokine levels were evaluated by ELISA. All chemotherapeutic agents presented anti-tumor properties similar to those of BCG. These included changes in immune cells that resulted in fewer M2 macrophages and regulatory T cells around tumors. This result was compatible with those in human samples. Intravesical chemotherapy also induced systemic changes in cytokines, especially urinary interleukin (IL)-17A and granulocyte colony stimulating factor (G-CSF), as well as in the distribution of blood neutrophils, lymphocytes, and monocytes. Our findings suggest that intravesical treatment with mitomycin C and adriamycin suppresses protumoral immunity while enhancing anti-tumor immunity, possibly through the action of specific cytokines. A better understanding of the immunoreaction induced by chemotherapeutic agents can lead to improved outcomes and fewer side effects in intravesical chemotherapy against NMIBC.

The IFO direct i.v. group showed a certain grade of renal injury as well as marked suppression of spermatogenesis, while the IV or IV+CV group showed no marked changes. The fertility test revealed that the male mice with IV+CV administration had normal fertility, and no malformations were detected in their progeny. This DDS model is of potential importance for clinical application in the therapy of metastatic osteosarcoma. PMID:25633802

    In this study, we developed functionalized superparamagnetic iron oxide (SPIO) nanoparticles consisting of a magnetic Fe3O4 core and a shell of aqueous stable polyethylene glycol (PEG) conjugated with doxorubicin (Dox) (SPIO-PEG-D) for tumor magnetic resonance imaging (MRI) enhancement and chemotherapy. The size of SPIO nanoparticles was ~10 nm, which was visualized by transmission electron microscope. The hysteresis curve, generated with vibrating-sample magnetometer, showed that SPIO-PEG-D was superparamagnetic with an insignificant hysteresis. The transverse relaxivity (r2) for SPIO-PEG-D was significantly higher than the longitudinal relaxivity (r1) (r2/r1 >10). The half-life of Dox in blood circulation was prolonged by conjugating Dox on the surface of SPIO with PEG to reduce its degradation. The in vitro experiment showed that SPIO-PEG-D could cause DNA crosslink more serious, resulting in a lower DNA expression and a higher cell apoptosis for HT-29 cancer cells. The Prussian blue staining study showed that the tumors treated with SPIO-PEG-D under a magnetic field had a much higher intratumoral iron density than the tumors treated with SPIO-PEG-D alone. The in vivo MRI study showed that the T2-weighted signal enhancement was stronger for the group under a magnetic field, indicating that it had a better accumulation of SPIO-PEG-D in tumor tissues. In the anticancer efficiency study for SPIO-PEG-D, the results showed that there was a significantly smaller tumor size for the group with a magnetic field than the group without. The in vivo experiments also showed that this drug delivery system combined with a local magnetic field could reduce the side effects of cardiotoxicity and hepatotoxicity. The results showed that the developed SPIO-PEG-D nanoparticles own a great potential for MRI-monitoring magnet-enhancing tumor chemotherapy. PMID:27274233

    Purpose/Objective(s) Optimal treatment for locally advanced rectal cancer (LARC) with distant metastasis remains elusive. We aimed to evaluate upfront systemic chemotherapy and short-course radiotherapy (RT) followed by delayed surgery for such patients, and to identify favorable prognostic factors. Materials/Methods We retrospectively reviewed 50 LARC patients (cT4 or cT3, <2 mm from the mesorectal fascia) with synchronous metastatic disease. The primary endpoint was progression-free survival (PFS). The secondary endpoints were overall survival, treatment-related toxicity, and compliance. We considered P values <0.05 significant. Results At 22 months median follow-up, the median PFS time was 16 months and the 2-year PFS rate was 34.8%. Thirty-five patients who received radical surgery for primary and metastatic tumors were designated the curable group. Six patients with clinical complete response (ypCR) of metastases who underwent radical surgery for only the primary tumor were classified as potentially curable. Nine patients who received no radical surgery (3 received palliative surgery) were deemed the palliative group. The ypCR rate among surgery patients was 13.6%. PFS rates for the curable or potentially curable groups were significantly longer than that of the palliative group (P<0.001). On multivariate analysis, solitary organ metastasis and R0 status were independent prognostic factors for PFS. Conclusions These findings demonstrated that a strong possibility that upfront chemotherapy and short-course RT with delayed surgery are an effective alternative treatment for LARC with potentially resectable distant metastasis, owing to achievement of pathologic down-staging, R0 resection, and favorable compliance and toxicity, despite the long treatment duration.

    The prognosis of patients with systemic lymphoma with central nervous system (CNS) involvement is very poor and there is no established standard therapy. We retrospectively analyzed 18 patients (4 untreated and 14 relapsed) with systemic lymphoma with CNS involvement who received methotrexate and cytarabine-based multiagent chemotherapy (modified Bonn protocol). Complete and partial responses were achieved in 56 and 22% of the patients, respectively. The 1-year overall survival (OS) and progression-free survival (PFS) was 81.0 and 39.2%, respectively. Patients with parenchymal involvement showed a better 1-year PFS than those with either leptomeningeal involvement or both. In a multivariate analysis, poor performance status (PS) was the only independent prognostic factor for the 1-year OS and PFS (HR 10.8, 95% CI 1.09-108, p = 0.042; HR 20.8, 95% CI 2.39-181, p = 0.006, respectively). Grade 4 neutropenia and thrombocytopenia occurred in 17 patients each (94%), but there were no grade 4 nonhematopoietic adverse events. The modified Bonn protocol resulted in relatively favorable response and survival, and provided clinical benefits to patients with good PS, in particular. This study demonstrated that the modified Bonn protocol could be a feasible and encouraging treatment approach for lymphoma with CNS and systemic involvement.

An extensive review of drug delivery systems, pharmaceuticals, patient monitoring, methods of enhancing inhaled drug deposition, safety and efficacy, and also additional applications of inhaled chemotherapy and its advantages and disadvantages are presented. Regional chemotherapy to the lung parenchyma for lung cancer is feasible and efficient. Safety depends on the chemotherapy agent delivered to the lungs and is dose-dependent and time-dependent. Further evaluation is needed to provide data regarding early lung cancer stages, and whether regional chemotherapy can be used as neoadjuvant or adjuvant treatment. Finally, inhaled chemotherapy could one day be administered at home with fewer systemic adverse effects.

    S-1 is an oral antitumor agent that contains tegafur, which is converted to fluorouracil (5-FU) in the human body. Cytochrome P450 2A6 (CYP2A6) is the principal enzyme responsible for bioconversion of tegafur to 5-FU. A number of CYP2A6 polymorphisms have been associated with variations in enzyme activity in several ethnic populations. The CYP2A6*4C allele leads to deletion of the entire CYP2A6 gene, and is the main finding in patients with reduced CYP2A6 enzymatic activity. Thus, the aim of our study was to evaluate the allele frequencies of CYP2A6 polymorphisms in a population with cancer of the digestive system. We developed a simple screening method, which combined TA cloning and direct-sequencing, to detect CYP2A6 genetic polymorphisms in Chinese patients with cancers of the digestive system. A total of 77 patients with various types of digestive system cancers were screened for CYP2A6 genetic polymorphisms. The allele frequencies of CYP2A6*1A, CYP2A6*1B and CYP2A6*4C in the 77 patients screened were 62, 42 and 13%, respectively. Frequencies of the homozygous genotypes for CYP2A6*1A and CYP2A6*4C were 27 and 12%, respectively. As expected, patients that were determined to be homozygous for CYP2A6*4C exhibited the characteristic chemotherapy efficacy and toxicity profiles. The TA cloning-based direct sequencing method facilitated allele frequency and genotyping determination for CYP2A6*1A, 1B and 4C of cancer patients. The findings indicated that the population carries a high frequency of the CYP2A6*4C homozygous genotype. Thus, the reduced efficacy of standard chemotherapy dosage in Chinese cancer patients may be explained by the lack of CYP2A6-mediated S-1 bioconversion to 5-FU.

    Gastric cancer is the fifth most common cancer worldwide. In "Western" countries, most people are either diagnosed at an advanced stage, or develop a relapse after surgery with curative intent. In people with advanced disease, significant benefits from targeted therapies are currently limited to HER-2 positive disease treated with trastuzumab, in combination with chemotherapy, in first-line. In second-line, ramucirumab, alone or in combination with paclitaxel, demonstrated significant survival benefits. Thus, systemic chemotherapy remains the mainstay of treatment for advanced gastric cancer. Uncertainty remains regarding the choice of the regimen. To assess the efficacy of chemotherapy versus best supportive care (BSC), combination versus single-agent chemotherapy and different chemotherapy combinations in advanced gastric cancer. We searched the Cochrane Central Register of Controlled Trials, MEDLINE and Embase up to June 2016, reference lists of studies, and contacted pharmaceutical companies and experts to identify randomised controlled trials (RCTs). We considered only RCTs on systemic, intravenous or oral chemotherapy versus BSC, combination versus single-agent chemotherapy and different chemotherapy regimens in advanced gastric cancer. Two review authors independently identified studies and extracted data. A third investigator was consulted in case of disagreements. We contacted study authors to obtain missing information. We included 64 RCTs, of which 60 RCTs (11,698 participants) provided data for the meta-analysis of overall survival. We found chemotherapy extends overall survival (OS) by approximately 6.7 months more than BSC (hazard ratio (HR) 0.3, 95% confidence intervals (CI) 0.24 to 0.55, 184 participants, three studies, moderate-quality evidence). Combination chemotherapy extends OS slightly (by an additional month) versus single-agent chemotherapy (HR 0.84, 95% CI 0.79 to 0.89, 4447 participants, 23 studies, moderate-quality evidence), which is

    Locally or recurrent advanced breast cancers can receive arterial blood supply from various arteries, such as the internal thoracic artery (ITA), the lateral thoracic artery, and the other small arterial branches originating from the subclavian artery. Failure to catheterize and subsequent formation of collateral arterial blood supply from various arteries are some of the reasons why the response to conventional selective transarterial infusion chemotherapy is limited and variable. To overcome this problem, we developed a new subclavian arterial infusion chemotherapy method using an implanted catheter-port system after redistribution of arterial tumor blood supply by embolizing the ITA. We named this technique ('redistributed subclavian arterial infusion chemotherapy' (RESAIC)). Using RESAIC, patients can be treated on an outpatient basis for extended periods of time. Eleven patients underwent RESAIC, and the complete remission and partial response rate in 10 evaluable patients was 90%: complete remission [CR] n = 4, partial remission n = 4, stable disease n = 1, and not evaluable n = 1. Three of four patients with CR had no distant metastasis, and modified radical mastectomy was performed 1 month after conclusion of RESAIC. The resected specimens showed no residual cancer cells, and pathologically confirmed complete remission was diagnosed in each of these cases. Although temporary grade-3 myelosuppression was seen in three patients who were previously treated by systemic chemotherapy, there was no other drug-induced toxicity or procedure-related complications. RESAIC produced a better response and showed no major complications compared with other studies despite the advanced stage of the cancers.

    In recent years, oncologists have begun to conclude that chemotherapy has reached a plateau of efficacy as a primary treatment modality, even if toxicity can be effectively controlled. Emerging specific inhibitors of signaling and metabolic pathways (i.e., targeted agents) contrast with traditional chemotherapy drugs in that the latter primarily interfere with the DNA biosynthesis and the cell replication machinery. In an attempt to improve on the efficacy, combination of targeted drugs with conventional chemotherapeutics has become a routine way of testing multiple new agents in early phase clinical trials. This review discusses the recent advances including integrative systematic biology and RNAi approaches to counteract the chemotherapy resistance and to buttress the selectivity, efficacy and personalization of anticancer drug therapy.

    The presence of malignant tumors during pregnancy complicates the management of both tumor and pregnancy, since any diagnostic or therapeutic intervention could imply risks that may bring on detrimental effects to fetus or mother. The risks involved in exposing a fetus to cytotoxic therapy are associated to gestational age and the time of in utero exposure to that therapy. Cancer treatment has two different objectives: local control by surgery and radiotherapy, and one that seeks to eradicate systemic disease through chemotherapy, immunotherapy, hormone therapy, or targeted therapies.

    Accumulating evidence indicates that the innate and adaptive immune systems make a crucial contribution to the antitumour effects of conventional chemotherapy-based and radiotherapy-based cancer treatments. Moreover, the molecular and cellular bases of the immunogenicity of cell death that is induced by cytotoxic agents are being progressively unravelled, challenging the guidelines that currently govern the development of anticancer drugs. Here, we review the immunological aspects of conventional cancer treatments and propose that future successes in the fight against cancer will rely on the development and clinical application of combined chemo- and immunotherapies.

    The sequential use of chemotherapy and surgery in the treatment of osteosarcoma developed in an empirical fashion without the benefit of investigations in animal models. The MGH-OGS murine osteosarcoma is a transplantable tumor that resembles the human disease with respect to histology, local invasiveness, metastatic characteristics, tumor ploidy, and its response to chemotherapy. We have used this tumor model to investigate the efficacy of preoperative, perioperative, and postoperative chemotherapy on the development of pulmonary metastases in three different experimental protocols. In each experimental design, perioperative chemotherapy demonstrated a significant advantage in preventing systemic relapse.

    Purpose: The prognosis for children with central nervous system primitive neuroectodermal tumor (CNS-PNET) or pinealoblastoma is still unsatisfactory. Here we report the results of patients between 4 and 21 years of age with nonmetastatic CNS-PNET or pinealoblastoma diagnosed from January 2001 to December 2005 and treated in the prospective GPOH-trial P-HIT 2000-AB4. Methods and Materials: After surgery, children received hyperfractionated radiation therapy (36 Gy to the craniospinal axis, 68 Gy to the tumor region, and 72 Gy to any residual tumor, fractionated at 2 × 1 Gy per day 5 days per week) accompanied by weekly intravenous administration of vincristine and followed by 8 cycles of maintenance chemotherapy (lomustine, cisplatin, and vincristine). Results: Twenty-six patients (15 with CNS-PNET; 11 with pinealoblastoma) were included. Median age at diagnosis was 11.5 years old (range, 4.0-20.7 years). Gross total tumor resection was achieved in 6 and partial resection in 16 patients (indistinct, 4 patients). Median follow-up of the 15 surviving patients was 7.0 years (range, 5.2-10.0 years). The combined response rate to postoperative therapy was 17 of 20 (85%). Eleven of 26 patients (42%; 7 of 15 with CNS-PNET; 4 of 11 with pinealoblastoma) showed tumor progression or relapse at a median time of 1.3 years (range, 0.5-1.9 years). Five-year progression-free and overall survival rates (±standard error [SE]) were each 58% (±10%) for the entire cohort: CNS-PNET was 53% (±13); pinealoblastoma was 64% (±15%; P=.524 and P=.627, respectively). Conclusions: Postoperative hyperfractionated radiation therapy with local dose escalation followed by maintenance chemotherapy was feasible without major acute toxicity. Survival rates are comparable to those of a few other recent studies but superior to those of most other series, including the previous trial, HIT 1991.

    Systemic administration of chemotherapy for cancer often has toxic side effects, limiting the doses that can be used in its treatment. In this study, we developed methoxy poly(ethylene glycol)-poly(caprolactone) (MPEG-PCL) micelles loaded with curcumin and doxorubicin (Cur-Dox/MPEG-PCL) that were tolerated by recipient mice and had enhanced antitumor effects and fewer side effects. It was shown that these Cur-Dox/MPEG-PCL micelles could release curcumin and doxorubicin slowly in vitro. The long circulation time of MPEG-PCL micelles and the slow rate of release of curcumin and doxorubicin in vivo may help to maintain plasma concentrations of active drug. We also demonstrated that Cur-Dox/MPEG-PCL had improved antitumor effects both in vivo and in vitro. The mechanism by which Cur-Dox/MPEG-PCL micelles inhibit lung cancer might involve increased apoptosis of tumor cells and inhibition of tumor angiogenesis. We found advantages using Cur-Dox/MPEG-PCL micelles in the treatment of cancer, with Cur-Dox/MPEG-PCL achieving better inhibition of LL/2 lung cancer growth in vivo and in vitro. Our study indicates that Cur-Dox/MPEG-PCL micelles may be an effective treatment strategy for cancer in the future.

    Recent research in chemotherapy has prioritized overcoming the multidrug resistance (MDR) of cancer cells. In this work, liposomes that contain doxorubicin (DOX) and ammonium bicarbonate (ABC, a bubble-generating agent) are prepared and functionalized with an antinucleolin aptamer (AS1411 liposomes) to target DOX-resistant breast cancer cells (MCF-7/ADR), which overexpress nucleolin receptors. Free DOX and liposomes without functionalization with AS1411 (plain liposomes) were used as controls. The results of molecular dynamic simulations suggest that AS1411 functionalization may promote the affinity and specific binding of liposomes to the nucleolin receptors, enhancing their subsequent uptake by tumor cells, whereas plain liposomes enter cells with difficulty. Upon mild heating, the decomposition of ABC that is encapsulated in the liposomes enables the immediate activation of generation of CO2 bubbles, creating permeable defects in their lipid bilayers, and ultimately facilitating the swift intracellular release of DOX. In vivo studies in nude mice that bear tumors demonstrate that the active targeting of AS1411 liposomes can substantially increase the accumulation of DOX in the tumor tissues relative to free DOX or passively targeted plain liposomes, inhibiting tumor growth and reducing systemic side effects, including cardiotoxicity. The above findings indicate that liposomes that are functionalized with AS1411 represent an attractive therapeutic alternative for overcoming the MDR effect, and support a potentially effective strategy for cancer therapy.

    The prognosis of patients with primary central nervous system lymphoma (PCNSL) has improved in recent years. This has partly been achieved by remission induction protocols incorporating high-dose methotrexate (HD-MTX) and rituximab. Given the high rates of relapse, consolidation therapy is usually considered in first response. Whole brain radiotherapy may prolong PFS but appears to confer no long-term survival advantage and is associated with significant neurocognitive dysfunction. Attempts to improve efficacy and reduce neurotoxicity of consolidation therapy have included thiotepa-based high-dose chemotherapy and autologous stem cell transplant (HDC-ASCT). This multi-centre, retrospective study reports the outcome of 70 patients undergoing HDC-ASCT for PCNSL in the United Kingdom. The median age at diagnosis was 56 years and all patients received HD-MTX-containing induction regimens. All patients underwent HDC-ASCT in first response. The rate of complete response increased from 50% before HDC-ASCT to 77% following HDC-ASCT. Treatment-related mortality was 6%. At a median follow-up of 12 months from HDC-ASCT, the estimated 1- and 2-year PFS rates were 71.5% and overall survival 86.4% and 83.3%, respectively. These data are comparable to published studies of HDC-ASCT for PCNSL, supporting its feasibility and efficacy.

    Corticosteroid and central nervous system (CNS) irradiation can induce cataract in childhood lymphoblastic leukaemia survivors. Few prospective studies with systematic ophthalmological evaluation have been published. Cataract was prospectively assessed by serial slip lamp tests in 517 patients. All had acute lymphoblastic leukaemia, all had been treated by chemotherapy with or without CNS irradiation, and none had received haematopoietic stem cell transplantation. Median ages at last evaluation and follow-up duration from leukaemia diagnosis were 16·8 and 10·9 years, respectively. Cataract was observed in 21/517 patients (4·1%). Cumulative incidence was 4·5 ± 1·2% at 15 years and reached 26 ± 8·1% at 25 years. CNS irradiation was the only risk factor: prevalence was 11·1% in patients who had received irradiation and 2·8% in those who did not. We did not detect any steroid dose effect: cumulative dose was 5133 and 5190 mg/m(2) in patients with and without cataract, respectively. Cataract occurrence did not significantly impact quality of life. We conclude that, in the range of steroid dose reported here, the cataract risk proves very low 15 years after treatment without CNS irradiation but an even more prolonged follow-up is required because of potential very late occurrence.

  20. Curative cancer chemotherapy.

    Cancer chemotherapy provides variably effective treatment for the majority of forms of human cancer and curative treatment for some 12 categories of cancer. Curative treatment is defined as the proportion of patients who survive beyond the time after which the risk of treatment failure approaches zero, i.e., the disease-free survival plateau. This progress has resulted from a closely integrated scientific effort, including drug development, pharmacology, preclinical modeling, experimental design with respect to clinical trials, quantitative criteria for response, and a series of clinical trials (initially in children with acute lymphocytic leukemia) in which the importance of complete remission, of dose and schedule, of sequencing chemotherapeutic agents, of pharmacological sanctuaries, and particularly of combination chemotherapy was studied. The principles derived from these studies, particularly those relating to combination chemotherapy, resulted in curative treatment for disseminated Hodgkin's disease, non-Hodgkin's lymphoma, pediatric solid tumors, testicular cancer, and limited small cell lung cancer. Many patients with certain stages of solid tumors, such as breast cancer and osteogenic sarcoma, are at high risk of having disseminated microscopic disease. Experimental studies indicate that treatment which is only partially effective against macroscopic disease is much more effective against microscopic tumors. Therefore chemotherapy is administered immediately following control of the primary tumor in patients at high risk of having disseminated microscopic disease, a treatment known as adjuvant chemotherapy. This program has been highly successful in increasing the cure rate in patients with pediatric solid tumors and in prolonging disease-free survival in patients with premenopausal breast cancer. Given dissemination of the technology, it is estimated that 15,000-30,000 patients per year are potentially curable in the United States. Curability of cancer

    Purpose Several established optical imaging approaches have been applied, usually in isolation, to preclinical studies; however, truly useful in vivo imaging may require a simultaneous combination of imaging modalities to examine dynamic characteristics of cells and tissues. We developed a new multimode optical imaging system designed to be application-versatile, yielding high sensitivity, and specificity molecular imaging. Procedures We integrated several optical imaging technologies, including fluorescence intensity, spectral, lifetime, intravital confocal, two-photon excitation, and bioluminescence, into a single system that enables functional multiscale imaging in animal models. Results The approach offers a comprehensive imaging platform for kinetic, quantitative, and environmental analysis of highly relevant information, with micro-to-macroscopic resolution. Applied to small animals in vivo, this provides superior monitoring of processes of interest, represented here by chemo-/nanoconstruct therapy assessment. Conclusions This new system is versatile and can be optimized for various applications, of which cancer detection and targeted treatment are emphasized here. PMID:21874388

    Chemotherapy has been the first-choice treatment for small-cell esophageal cancer (SCEC), etoposide plus cisplatin or carboplatin (EP/CP) is the most commonly recommended chemotherapeutical strategy. However, the choice of chemotherapy in treating SCEC has not been validated by studies of large cohorts of cases because of the rarity of the malignancy, and the efficacy superiority of EP/CP over other chemotherapy combinations has not been confirmed. The present case series analysis was conducted to address the above issues. Reported studies of SCEC patients were retrieved. Case series with more than five patients were enrolled. Eight patients treated in our institute were also included as another case series. Data pertaining to clinical stages, treatment regimens, and survival time were collected and analyzed. Altogether, 19 SCEC case series were enrolled, including 164 male and 61 female patients with a median age of 63.5 years. The follow-up time ranged from 0.1 to 221 months (median 12.3 months). The median survival time (MST) was 19 months for limited disease (LD) patients (124 cases) and 9 months for extensive disease (ED) patients (88 cases) (P<0.001). For LD patients, MST was obviously prolonged by chemotherapeutical regimens (20 vs. 10 months, P<0.01), whereas this superiority was not proved in ED patients (10 vs. 10 months, P>0.05). EP/CP did not result in significantly longer MST, compared with that of the cases treated by other chemotherapy combinations (P>0.05, for either LD or ED cases). Chemotherapy prolongs the survival time of the LD SCEC patients, which indicates that chemotherapeutical treatment is effective for SCEC. EP/CP, as commonly recommended multidrug chemotherapy regimen, is not superior to other chemotherapy combinations. © 2013 Wiley Periodicals, Inc. and the International Society for Diseases of the Esophagus.

    Adrenal lymphoma is extremely rare. The prognostic depends on involvement of other organs (such as the central nervous system) responsible for lower median survival. We report the case of a 51-year-old man with non Hodgkin's Diffuse Large B Cell Lymphoma (DLBCL) involving the central nervous system (CNS) and the adrenal glands simultaneously. The endocrine exploration revealed a partial adrenal insufficiency and ruled out a pheochromocytoma. Computerized tomographic (CT) scan directed needle biopsy of the adrenal gland allowed the diagnostic of non-Hodgkin lymphoma (NHL). CNS biopsies showed similar histopathologic lesions. After aggressive polychemotherapy and methotrexate intrathecal injection, a dissociated therapeutic response was observed with a decrease of the cerebral lesion and an increase of the adrenal mass. This result may be explained by the efficacy of corticosteroid therapy on cerebral edema. The prognosis was poor with tumor infiltration of the leptomeninges and death 16 months after diagnosis.

    Efficacy of cancer chemotherapy is generally believed to be the result of direct drug killing of tumor cells. However, increased tumor cell killing does not always lead to improved efficacy. Herein, we demonstrate that the status of antitumor immunity at the time of chemotherapy treatment is a critical factor affecting the therapeutic outcome in that tumor-bearing mice that possess preexisting antitumor immunity respond to chemotherapy much better than those that do not. Enhancing antitumor immunity before or at the time of chemotherapy-induced antigen release increases subsequent response to chemotherapy significantly. By in vitro and in vivo measurements of antitumor immunity, we found a close correlation between the intensity of antitumor immunity activated by chemotherapy and the efficacy of treatment. Immune intervention with interleukin-12 during the early phase of chemotherapy-induced immune activation greatly amplifies the antitumor response, often resulting in complete tumor eradication not only at the chemo-treated local site, but also systemically. These findings provide additional evidence for an immune-mediated antitumor response to chemotherapy. Further, our results show that timely immune modification of chemotherapy-activated antitumor immunity can result in enhanced antitumor-immune response and complete tumor eradication.

    Herein a novel multi-controlled drug release system for doxorubicin (DOX) was developed, in which monodisperse mesoporous Fe3O4 nanoparticles were combined with a phase change material (PCM) and polyethylene glycol 2000 (PEG2000). It is found that the PCM/PEG/DOX mixture containing 20% PEG could be dissolved into water at 42 °C. The mesoporous Fe3O4 nanoparticles prepared by the solvothermal method had sizes of around 25 nm and exhibited a mesoporous microstructure. A simple solvent evaporation process was employed to load the PCM/PEG/DOX mixture on the mesoporous Fe3O4 nanoparticles completely. In the Fe3O4@PCM/PEG/DOX system, the pores of the Fe3O4 nanoparticles were observed to be filled with the mixture of PCM/PEG/DOX. The Fe3O4@PCM/PEG/DOX system showed a saturation magnetization value of 50.0 emu g(-1), lower than 71.1 emu g(-1) of the mesoporous Fe3O4 nanoparticles, but it was still high enough for magnetic targeting and hyperthermia application. The evaluation on drug release performance indicated that the Fe3O4@PCM/PEG/DOX system achieved nearly zero release of DOX in vitro in body temperature, while around 80% of DOX could be released within 1.5 h at the therapeutic threshold of 42 °C or under the NIR laser irradiation for about 4 h. And a very rapid release of DOX was achieved by this system when applying an alternating magnetic field. By comparing the systems with and without PEG2000, it is revealed that the presence of PEG2000 makes DOX easy to be released from 1-tetradecanol to water, owing to its functions of increasing the solubility of DOX in 1-tetradecanol as well as decreasing the surface tension between water and 1-tetradecanol. The novel drug release system shows great potential for the development of thermo-chemotherapy of cancer treatment.

    Patients with cholangiocarcinoma usually present at an advanced stage, and more than 50% of cases are not resectable at the time of diagnosis. Recently, photodynamic therapy (PDT) has been proposed as a palliative and neoadjuvant modality. We evaluated whether combination of PDT and chemotherapy is more effective than PDT alone. In total, 161 patients with cholangiocarcinoma diagnosed between February 1999 and September 2009 were evaluated. Sixteen patients were treated with PDT and chemotherapy (group A), and 58 were treated with PDT (group B). The median survival was 538 days (95% confidence interval [CI], 475.3 to 600.7) in group A and 334 days (95% CI, 252.5 to 415.5) in group B (p=0.05). Lymph node metastasis status, serum bilirubin of pretreatment, tumor node metastasis stage, treatment method (PDT with chemotherapy vs PDT alone), time to PDT and the number of PDT sessions were prognostic factors with statistical significance in the univariate analysis. A multivariate analysis showed that PDT with chemotherapy and more than two sessions of PDT were significant independent predictors of longer survival in advanced cholangiocarcinoma (hazard ratio [HR], 2.23; 95% CI, 1.18 to 4.20; p=0.013 vs HR, 1.79; 95% CI, 1.044 to 3.083; p=0.034). PDT with chemotherapy results in longer survival than PDT alone.

    The purpose of this study was to prospectively compare the efficacy and controllability of pushable coil and detachable coil during embolization of gastroduodenal artery (GDA) while performing percutaneous implantation of port-catheter system for hepatic artery infusion chemotherapy. Fifty patients (M:F = 42:8, age: 31-81 years) with advanced hepatocellular carcinoma undergoing port-catheter system implantation were randomized into pushable coil group and detachable coil group. During catheter fixation, GDA was embolized as close to the origin as possible. Success rate, number of coils used, number of coils removed due to malposition after deployment, time to occlusion, uncoiled GDA length, pushability, and complications were compared. Pushability was graded as no tension, slight tension, and difficult to advance. Embolization was successful in 49 patients. One failure resulted from repeated regurgitation of pushable coil into hepatic artery. Number of coils used and removed coils, time to occlusion, and uncoiled GDA length were 1-3 (mean 2.32), 5 coils in 3 patients, 4-20 min (mean 8.00), and 0-15.0 mm (mean 3.36) in pushable coil group, and 1-5 (mean 2.12), 2 coils in 2 patients, 2-15 min (mean 7.40), and 0-10.2 mm (mean 2.92) in detachable coil group, respectively, without significant difference. Pushability was no tension (n = 24) and slight tension (n = 1) in pushable coil group and no tension (n = 16), slight tension (n = 7), and difficult to advance (n = 2) in detachable coil group. One hepatic artery dissection occurred in the failed case during coil removal. Pushable coils and detachable coils had similar efficacy and controllability during GDA embolization, although there was a trend favoring detachable coil.

    Exposure to the EGFR (epidermal growth factor receptor) inhibitor erlotinib promotes the dynamic rewiring of apoptotic pathways, which sensitizes cells within a specific period to subsequent exposure to the DNA-damaging agent doxorubicin. A critical challenge for translating this therapeutic network rewiring into clinical practice is the design of optimal drug delivery systems. We report the generation of a nanoparticle delivery vehicle that contained more than one therapeutic agent and produced a controlled sequence of drug release. Liposomes, representing the first clinically approved nanomedicine systems, are well-characterized, simple, and versatile platforms for the manufacture of functional and tunable drug carriers. Using the hydrophobic and hydrophilic compartments of liposomes, we effectively incorporated both hydrophobic (erlotinib) and hydrophilic (doxorubicin) small molecules, through which we achieved the desired time sequence of drug release. We also coated the liposomes with folate to facilitate targeting to cancer cells. When compared to the time-staggered application of individual drugs, staggered release from tumor-targeted single liposomal particles enhanced dynamic rewiring of apoptotic signaling pathways, resulting in improved tumor cell killing in culture and tumor shrinkage in animal models.

    This prospective experimental simulation study evaluated the efficiency, ease of use (EOU) and cost of administering chemotherapy with two closed system transfer devices (CSTD, Equashield™ and PhaSeal(®) ) and no CSTD. Forty-six veterinary technicians (VT) working in oncology specialty practices were timed during chemotherapy administration simulated with water and a model canine limb 10 times with each system and with no CSTD. EOU and likelihood of recommending each system were rated by VT using visual analog scales. Costs were obtained from veterinary distributors. Administration was fastest with Equashield™ (P = 0.0003), but the difference was not enough to affect case flow. Equashield™ was easier to use than PhaSeal(®) or no CSTD (P = 0.002), however VT recommended both CSTD more strongly than no CSTD (P < 0.0001). Equashield™ cost less than PhaSeal(®) but was sold only in bulk quantities. CSTD did not decrease efficiency in administering chemotherapy and were readily accepted by VT. © 2015 John Wiley & Sons Ltd.

    The treatment of patients with brain tumors has long been the domain of neurosurgery and radiotherapy but chemotherapy is now well established as an additional treatment option for many tumor entities in neuro-oncology. This is particularly true for patients with newly diagnosed and relapsing glioblastoma and anaplastic glioma as well as the treatment of medulloblastoma and primary lymphoma of the central nervous system (CNS). In addition to purely histopathological features, treatment decisions including those for chemotherapy are now based increasingly more on molecular tumor profiling. Within the group of gliomas these markers include the methylation status of the O-6-methylguanine-DNA methyltransferase (MGMT) promoter and the 1p/19q status, which reflects the loss of genetic material on chromosome arms 1p and 19q. The presence of a 1p/19q codeletion is associated with a better prognosis and increased sensitivity to alkylating chemotherapy in patients with anaplastic gliomas.

    Cancer diagnosed during pregnancy is uncommon, complicating between 0.02% and 0.1% of all pregnancies. Nonetheless, due to increasing age of childbearing, the incidence of cancer during pregnancy is likely to increase due to higher incidence of several age-dependent malignancies. The most common malignancies include breast cancer, cervical cancer, malignant melanoma and lymphoma. One of the key challenges in the management of cancer in pregnancy is treating the women with standard chemotherapy regimen, without compromising the safety of the developing foetus. Exposure of chemotherapy in the first trimester is associated with an increased risk of major birth defects, whereas use in the second and third trimesters is associated with intrauterine growth restriction, low birthweight and stillbirth. In this article, we review available data regarding the use of chemotherapeutic agents in pregnancy, and we summarise the neonatal outcomes, including malformations, perinatal complications and long-term follow-up. In addition, the management plan during pregnancy is also discussed.

    In colorectal cancer (CRC), unresectable liver metastases are linked to poor prognosis. Systemic chemotherapy with regimens such as FOLFOX (combination of infusional 5-fluorouracil, leucovorin and oxaliplatin) is the standard first-line treatment. The SIRFLOX trial was designed to assess the efficacy and safety of combining FOLFOX-based chemotherapy with Selective Internal Radiation Therapy (SIRT or radioembolisation) using yttrium-90 resin microspheres (SIR-SpheresR; Sirtex Medical Limited, North Sydney, Australia). SIRFLOX is a randomised, multicentre trial of mFOLFOX6 chemotherapy+/-SIRT as first-line treatment of patients with liver-only or liver-predominant metastatic CRC (mCRC). The trial aims to recruit adult chemotherapy-naive patients with proven liver metastases with or without limited extra-hepatic disease, a life expectancy of >=3 months and a WHO performance status of 0-1. Patients will be randomised to receive either mFOLFOX6 or SIRT+mFOLFOX6 (with a reduced dose of oxaliplatin in cycles 1-3 following SIRT). Patients in both arms can receive bevacizumab at investigator discretion. Protocol chemotherapy will continue until there is unacceptable toxicity, evidence of tumour progression, complete surgical resection or ablation of cancerous lesions, or the patient requests an end to treatment. The primary endpoint of the SIRFLOX trial is progression-free survival (PFS). Secondary endpoints include: PFS in the liver; tumour response rate (liver and any site); site of tumour progression; health-related quality of life; toxicity and safety; liver resection rate; and overall survival. Assuming an increase in the median PFS from 9.4 months to 12.5 months with the addition of SIRT to mFOLFOX6, recruiting >=450 patients will be sufficient for 80% power and 95% confidence. The SIRFLOX trial will establish the potential role of SIRT+standard systemic chemotherapy in the first-line management of mCRC with non-resectable liver metastases. SIRFLOX Clinical

    Background. In some patients with hepatic tumors, anatomic variations in the hepatic arteries may require hemodynamic modification to render effective hepatic arterial infusion chemotherapy delivered via implantable port systems. We used a combined CT/SPECT system to obtain fused images of the intrahepatic perfusion patterns in patients with such anatomic variations and assessed their effects on the treatment response of hepatic tumors. Methods. Using a combined SPECT/CT system, we obtained fused images in 110 patients with malignant liver tumors (n = 75) or liver metastasis from unresectable pancreatic cancer (n = 35). Patients with anatomic hepatic arteries variations underwent hemodynamic modification before the placement of implantable port systems for hepatic arterial infusion chemotherapy. We evaluated their intrahepatic perfusion patterns and the initial treatment response of their liver tumors. The perfusion patterns on the fused images were classified as homogeneous, local hypoperfusion, and/or perfusion defect. Using the WHO criteria of complete response (CR), partial response (PR), no change (NC), and progressive disease (PD), we evaluated the patients' tumor responses after 3 months on multislice helical CT scans. The treatment was regarded as effective in patients who achieved a complete response or partial response. Results. Anatomic hepatic artery variations were present in 15 of the 110 patients (13.6%); 5 manifested replacement of the left hepatic artery (LHA), 8 of the right hepatic artery (RHA), and 1 each had replacement of the RHA and LHA, and replacement of the LHA plus an accessory RHA. In 13 of these 15 patients (87%), occlusion with metallic coils was successful. On fusion imaging, the perfusion patterns were recorded as homogeneous in 6 patients (43%), as hypoperfusion in 7 (50%), and 1 patient had a perfusion defect (7.1%) in the embolized arterial region. Of the 8 patients with RHA replacement, 4 manifested a homogeneous distribution and

    Injectable polymers that are biocompatible and biodegradable are important biomaterials for drug delivery system (DDS) and tissue engineering. We have already developed novel tissue adhesives consisting of biomacromolecules and organic acid derivatives with active ester groups. The resulting tissue adhesive forms in situ as a gel and has high bonding strength for living tissue as well as it has good biocompatibility and biodegradability. Here, we report on the physicochemical properties and in vitro evaluation of this novel tissue adhesive consisting of human serum albumin (HSA) and tartaric acid derivative (TAD) containing doxorubicin hydrochloride (DOX). The results of the measurement of physicochemical characteristics indicate that the gelation time and gel strength of HSA-TAD gels can be controlled according to the material composition. The bonding strength of HSA-TAD adhesives was found to be sufficient to adhere at focus and to correspond with the cross-linking density of HSA-TAD gels. Furthermore, the release of DOX from HSA-TAD gels was sustained for approximately 100 h in an in vitro evaluation. The novel tissue adhesive, therefore, is expected to be applicable for use as an injectable in situ forming DDS.

    In this research, a thermoresponsive drug release system was synthesized, which encapsulated the magnetic nanoparticles Fe3O4 and the drug model 5-fluorouracil with thermosensitive polymer poly(N-isopropylacrylamide) (PNIPAM). Mesoporous SiO2 was used as the channel of drug release, which could enhance the rate of drug loading and reduce drug loss. Chitosan (CHI) is a natural cationic linear polymer. The results showed successful coating of chitosan and rhodamine 6G (R6G) on the surface of the SiO2 sphere. The intermolecular interactions of the nanocomposites were confirmed by Fourier transform infrared spectroscopy. R6G is a typical fluorochrome which could be applied for cell imaging. Fluorescent imaging studies by confocal laser scanning microscopy indicated that the prepared nanocomposites Fe3O4/PNIPAM/5-Fu@mSiO2-CHI/R6G could specifically target tumor cells. Therefore, our work shows great potential in drug delivery and cancer therapy.

    We hypothesized that methotrexate (MTX) normalizes the increased permeability of the blood-tumor barrier and thus reduces the accessibility of rituximab (RTX) to central nervous system (CNS) lymphoma. Here, we evaluated the combinational treatment capability of RTX and MTX using an alternative treatment schedule against CNS lymphoma. We developed a CNS lymphoma animal model that closely mimics the morphological and molecular characteristics of human CNS lymphoma by injecting Raji human Burkitt lymphoma cells into the brains of immune-compromised mice and tested a novel combinational treatment schedule by which penetration of RTX was not influenced by MTX administration. RTX was conjugated with Alexa Fluor 680, and its distribution in the brain was analyzed by in vivo imaging. When MTX treatment was followed by a 3-day post RTX administration, RTX was scarcely distributed in the brain, and there were only modest statistically insignificant therapeutic effects compared with the control mice which received sham injections. In contrast, RTX administration followed by a 3-day post MTX treatment showed significantly increased distribution of RTX and significantly reduced tumor volume in the brain. Collectively, our data demonstrate that RTX can be successfully combined with MTX using an alternative treatment schedule that allows increased distribution of RTX in CNS lymphoma. PMID:22993623

    Sixty-four patients were entered into a randomized trial that evaluated intra-arterial (I.A.) versus intravenous (I.V.) 5-fluorodeoxyuridine (FUDR) for colorectal liver metastases. There was a significant improved response rate for I.A. (62%) compared with I.V. (17%) treatment (p less than 0.003). However, the improved response rate for patients in whom I.A. therapy was used did not translate to a significantly improved survival rate. The 2-year actuarial survival rates for the groups for which I.A. and I.V. therapy was used were 22% and 15% respectively, with the survival curves not differing significantly (p = 0.27). These results may have been due to the inclusion of patients with tumor in draining hepatic lymph nodes. The presence of tumor in hepatic lymph nodes was associated with a poorer prognosis. Analysis of a subgroup of patients with negative hepatic lymph nodes suggested an improved actuarial survival rate in patients for whom I.A. versus I.V. therapy was used (p less than 0.03). The toxicity of I.A. FUDR was considerable, and side effects included chemical hepatitis (79%), biliary sclerosis (21%), peptic ulcers (17%), and gastritis/duodenitis (21%). The only major effect of toxicity of I.V. FUDR was severe diarrhea (59%). Regional I.A. FUDR allowed more drug delivery to liver tumors, which resulted in increased tumor responses when compared with use of systemic therapy. However, the small gain in survival seen in a select subgroup of patients with negative hepatic nodes appeared to be offset by the toxicity of I.A. FUDR. Images Figs. 1A-D. PMID:2961314

    Low-dose, Visudyne®-mediated photodynamic therapy (photo-induction) was shown to selectively enhance tumor vessel transport causing increased uptake of systemically administered chemotherapy in various tumor types grown on rodent lungs. The present experiments explore the efficacy of photo-induced vessel modulation combined to intravenous (IV) liposomal cisplatin (Lipoplatin®) on rodent lung tumors and the feasibility/toxicity of this approach in porcine chest cavities. Three groups of Fischer rats underwent orthotopic sarcoma (n = 14), mesothelioma (n = 14), or adenocarcinoma (n = 12) implantation on the left lung. Half of the animals of each group had photo-induction (0.0625 mg/kg Visudyne®, 10 J/cm(2) ) followed by IV administration of Lipoplatin® (5 mg/kg) and the other half received Lipoplatin® without photo-induction. Then, two groups of minipigs underwent intrapleural thoracoscopic (VATS) photo-induction (0.0625 mg/kg Visudyne®; 30 J/cm(2) hilum; 10 J/cm(2) apex/diaphragm) with in situ light dosimetry in combination with IV Lipoplatin® administration (5 mg/kg). Protocol I (n = 6) received Lipoplatin® immediately after light delivery and Protocol II (n = 9) 90 minutes before light delivery. Three additional animals received Lipoplatin® and VATS pleural biopsies but no photo-induction (controls). Lipoplatin® concentrations were analyzed in blood and tissues before and at regular intervals after photo-induction using inductively coupled plasma mass spectrometry. Photo-induction selectively increased Lipoplatin® uptake in all orthotopic tumors. It significantly increased the ratio of tumor to lung Lipoplatin® concentration in sarcoma (P = 0.0008) and adenocarcinoma (P = 0.01) but not in mesothelioma, compared to IV drug application alone. In minipigs, intrapleural photo-induction combined to systemic Lipoplatin® was well tolerated with no toxicity at 7 days for both treatment protocols. The pleural

    Objective To explore genes of the killer-cell immunoglobulin-like receptor (KIR) and of the HLA ligand and their relationship with the outcome of metastatic colorectal cancer (mCRC) patients treated with first-line 5-fluorouracil, leucovorin, and irinotecan (FOLFIRI). Methods A total of 224 mCRC patients were screened for KIR/HLA typing. The determination of the KIR/HLA combinations was based upon the gene content and variants. Genetic associations with complete response (CR), time to progression (TTP) and overall survival (OS) were evaluated by calculating odds and hazard ratios. Multivariate modeling with prognostic covariates was also performed. Results For CR, the presence of KIR2DL5A, 2DS5, 2DS1, 3DS1, and KIR3DS1/HLA-Bw4-I80 was associated with increased CR rates, with median ORs ranging from 2.1 to 4.3, while the absence of KIR2DS4 and 3DL1 was associated with increased CR rates (OR 3.1). After univariate analysis, patients that underwent resective surgery of tumor, absence of KIR2DS5, and presence of KIR3DL1/HLA-Bw4-I80 showed a significant better OS (HR 1.5 to 2.8). Multivariate analysis identified as parameters independently related to OS the type of treatment (surgery; HR 2.0) and KIR3DL1/HLA-Bw4-I80 genotype (HR for T-I80 2.7 and for no functional KIR/HLA interaction 1.8). For TTP, no association with KIR/HLA genes was observed. Conclusion This study, for the first time, evidences that the genotyping for KIR-HLA pairs are found predictive markers associated with complete response and improves overall survival prediction of FOLFIRI treatment response in metastatic colorectal cancer. These results suggest a role of the KIR/HLA system in patient outcome, and guide new research on the immunogenetics of mCRC through mechanistic studies and clinical validation. PMID:24497922

    This aim of this study was to develop peptide-conjugated nanoparticles (NPs) for systemic co-delivery of siRNA and doxorubicin to enhance chemotherapy in epidermal growth factor receptor (EGFR) high-expressed ovarian tumor bearing mice. The active targeting NPs were prepared using heptapeptide-conjugated poly( d, l-lactic-co-glycolic acid)-poly(ethylene glycol). The particle sizes of peptide-free and peptide-conjugated NPs were 159.3 ± 32.5 and 184.0 ± 52.9 nm, respectively, with zeta potential -21.3 ± 3.8 and -15.3 ± 2.8 mV. The peptide-conjugated NPs uptake were more efficient in EGFR high-expressed SKOV3 cells than in EGFR low-expressed HepG2 cells due to heptapeptide specificity. The NPs were used to deliver small molecule anticancer drug (e.g., doxorubicin) and large molecule genetic agent (e.g., siRNA). The IC50 of doxorubicin-loaded peptide-conjugated NPs (0.09 ± 0.06 μM) was significantly lower than peptide-free NPs (5.72 ± 2.64 μM). The similar result was observed in siRNA-loaded NPs. The peptide-conjugated NPs not only served as a nanocarrier to efficiently deliver doxorubicin and siRNA to EGFR high-expressed ovarian cancer cells but also increased the intracellular accumulation of the therapeutic agents to induce assured anti-tumor growth effect in vivo.

To ensure that women of child-bearing age receiving chemotherapy can be appropriately counselled on the risks of becoming pregnant during treatment, and to provide guidance for health care practitioners treating pregnant women with antineoplastic agents. Published literature was retrieved through searches of PubMed or Medline, CINAHL, and The Cochrane Library in 2011, using appropriate controlled vocabulary (e.g., antineoplastic agents, neoplasms, pregnancy) and key words (e.g., cancer, neoplasms, pregnancy, chemotherapy, antineoplastic agents). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Studies were restricted to those with available English abstracts or text. Searches were updated on a regular basis and incorporated in the guideline to October 2011. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and from national and international medical specialty societies. The quality of evidence is rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). This guideline highlights the need to prevent pregnancy in women who are being treated for cancer and informs health care professionals treating pregnant women with chemotherapy of the potential risks of the therapy or ameliorated treatment protocols.

    Doxorubicin is a widely used and effective chemotherapy drug. However, cardiac and skeletal muscle toxicity of doxorubicin limits its use. Inhibiting myostatin/activin signalling can prevent muscle atrophy, but its effects in chemotherapy-induced muscle wasting are unknown. In the present study we investigated the effects of doxorubicin administration alone or combined with activin receptor ligand pathway blockade by soluble activin receptor IIB (sACVR2B-Fc). Doxorubicin administration decreased body mass, muscle size and bone mineral density/content in mice. However, these effects were prevented by sACVR2B-Fc administration. Unlike in many other wasting situations, doxorubicin induced muscle atrophy without markedly increasing typical atrogenes or protein degradation pathways. Instead, doxorubicin decreased muscle protein synthesis which was completely restored by sACVR2B-Fc. Doxorubicin administration also resulted in impaired running performance without effects on skeletal muscle mitochondrial capacity/function or capillary density. Running performance and mitochondrial function were unaltered by sACVR2B-Fc administration. Tumour experiment using Lewis lung carcinoma cells demonstrated that sACVR2B-Fc decreased the cachectic effects of chemotherapy without affecting tumour growth. These results demonstrate that blocking ACVR2B signalling may be a promising strategy to counteract chemotherapy-induced muscle wasting without damage to skeletal muscle oxidative capacity or cancer treatment.

    Purpose: To evaluate cosmetic outcome and radiation recall in the American Society of Breast Surgeons registry trial, as a function of the interval between accelerated partial breast irradiation (APBI) and initiation of chemotherapy (CTX). Methods and Materials: A total of 1440 patients at 97 institutions participated in this trial. After lumpectomy for early-stage breast cancer, patients received APBI (34 Gy in 10 fractions) with MammoSite RTS brachytherapy. A total of 148 patients received CTX within 90 days of APBI. Cosmetic outcome was evaluated at each follow-up visit and dichotomized as excellent/good or fair/poor. Results: Chemotherapy was initiated at a mean of 3.9 weeks after the final MammoSite procedure and was administered {<=}3 weeks after APBI in 54 patients (36%) and >3 weeks after APBI in 94 patients (64%). The early and delayed groups were well balanced with respect to multiple factors that may impact on cosmetic outcome. There was a superior cosmetic outcome in those receiving chemotherapy >3 weeks after APBI (excellent/good in 72.2% at {<=}3 weeks vs. excellent/good in 93.8% at >3 weeks; p = 0.01). Radiation recall in those receiving CTX at {<=}3 weeks was 9 of 50 (18%), compared with 6 of 81(7.4%) in those receiving chemotherapy at >3 weeks (p = 0.09). Conclusion: The majority of patients receiving CTX after APBI have excellent/good cosmetic outcomes, with a low rate of radiation recall. Chemotherapy initiated >3 weeks after the final MammoSite procedure seems to be associated with a better cosmetic outcome and lower rate of radiation recall. An excellent/good cosmetic outcome in patients receiving CTX after 3 weeks was similar to the cosmetic outcome of the overall patient population who did not receive CTX.

  7. Relationships between hypoxia markers and the leptin system, estrogen receptors in human primary and metastatic breast cancer: effects of preoperative chemotherapy

    PubMed Central

    2010-01-01

    Background Tumor hypoxia is marked by enhanced expression of hypoxia-inducible factor-α (HIF-1α) and glucose transporter-1 (Glut-1). Hypoxic conditions have also been associated with overexpression of angiogenic factors, such as leptin. The aim of our study was to analyze the relationships between hypoxia markers HIF-1α, Glut-1, leptin, leptin receptor (ObR) and other breast cancer biomarkers in primary and metastatic breast cancer in patients treated or untreated with preoperative chemotherapy. Methods The expression of different biomarkers was examined by immunohistochemistry in 116 primary breast cancers and 65 lymph node metastases. Forty five of these samples were obtained form patients who received preoperative chemotherapy and 71 from untreated patients. Results In primary tumors without preoperative chemotherapy, HIF-1α and Glut-1 were positively correlated (p = 0.02, r = 0.437). HIF-1α in primary and metastatic tumors without preoperative therapy positively correlated with leptin (p < 0.0001, r = 0.532; p = 0.013, r = 0.533, respectively) and ObR (p = 0.002, r = 0.319; p = 0.083, r = 0.387, respectively). Hypoxia markers HIF-1α and Glut-1 were negatively associated with estrogen receptor alpha (ERα) and positively correlated with estrogen receptor beta (ERβ). In this group of tumors, a positive correlation between Glut-1 and proliferation marker Ki-67 (p = 0.017, r = 0.433) was noted. The associations between HIF-1α and Glut-1, HIF-1α and leptin, HIF-1α and ERα as well as Glut-1 and ERβ were lost following preoperative chemotherapy. Conclusions Intratumoral hypoxia in breast cancer is marked by coordinated expression of such markers as HIF-1α, Glut-1, leptin and ObR. The relationships among these proteins can be altered by preoperative chemotherapy. PMID:20569445

  8. Secondary malignancies following cancer chemotherapy.

    Many agents used in cancer chemotherapy are known carcinogens. However, few secondary malignancies have been definitely linked to chemotherapy, since studies on this problem are complicated by methodological problems. A causal relationship has been established between alkylating agents and leukaemia and between cyclophosphamide and bladder cancer. The risk of leukaemia peaks at 5-10 years after beginning of chemotherapy and declines steadily after its end. The interaction between chemotherapy and radiotherapy has not been fully clarified, nor has the leukaemogenic potency of individual drugs, although combinations without nitrogen mustard seem to entail a lower risk. Other tumours reported at increased incidence, in particular among Hodgkin's disease patients, for whom a carcinogenic effect of chemotherapy seems plausible, are non-Hodgkin's lymphoma and lung cancer. Other secondary solid tumors have also been reported, but for none of them an independent effect of chemotherapy has been demonstrated.

    In order to get mature dendritic cells (DC) that is a crucial prerequisite for success in tumor immunotherapy protocols. Herein, we assumed that administration of murine bone marrow (BM)-derived DC (BM-DC), loaded ex vivo with whole Ehrlich ascites carcinoma (EAC) lysate, in the context of systemic chemotherapy cyclophosphamide (CTX) to induce antitumor immune responses, may be a good strategy to improve the presentation of tumor-specific antigens to the immune system. In the first series of experiments, BM cells generated either from BM of naïve mice or from BM of EAC-bearing mice were cultured in the presence of GM-CSF and IL-4 for 6days. At day 7, cells were loaded for 48h with one of the following maturation agents: EAC lysate (1mg/ml), poly-inosinic: polycytidylic acid [poly(I:C)] (25μg/ml) or mRNA encoding human telomerase reverse transcriptase (hTERT-mRNA) (2μg/ml). In the second series of experiments, EAC-bearing mice were intraperitoneally (i.p.) injected with CTX followed by i.p. vaccination with DC, loaded ex vivo with EAC lysate. DC yield and the phenotypic expression of maturity-related surface markers of DC (i.e. CD11b and CD11c) in both series of experiments were investigated. As a result, a significant decrease in the number of DC generated from poly(I:C)-supplemented BM culture from EAC-bearing mice has been detected. Loading of BM cells with poly(I:C), EAC lysate or hTERT-mRNA could induce the expression of CD11b and CD11c. Additionally, vaccination of EAC-bearing mice with DC loaded ex vivo with EAC lysate following CTX treatment, resulted in increases in the percentage of multiple populations of CD11b(+)CD11c(+) in BM, spleen and peripheral blood (PB). To conclude, further researches to clarify the mechanism involved in DC maturation are crucial not only to comprehend DC biology but also to optimize DC immunotherapy protocols.

    BACKGROUND Patients with multiple liver metastases from colorectal cancer are at high risk of recurrence after resection. Hepatic artery infusion (HAI) alternating with systemic therapy after surgical resection may improve survival following surgery. METHODS Patients with liver-only metastases from colorectal cancer amenable to resection/cryoablation were eligible. Prior adjuvant chemotherapy for a completely resected primary was allowed. Alternating courses of HAI and systemic therapy included floxuridine (FUDR) via HAI. Systemic chemotherapy consisted of bolus leucovorin plus 5-fluorouracil (5-FU). RESULTS 49 patients were able to undergo complete resection of their liver metastases with 44% having more than 4 hepatic metastases and 78% having bilobar disease. 36 patients were able to initiate HAI FUDR alternating with systemic therapy. Patients received a median of 3.5 cycles (range 1–4) and 3 cycles (range 0–6) of therapy with HAI FUDR and systemic therapy, respectively. At the time of the final analysis the estimated median disease-free survival and hepatic disease-free survival are 1.2 years (95% CI: 0.9–2.1) and 1.8 years (95% CI: 1.8-NA), respectively. Eleven patients (31%) are alive. All surviving patients have a minimum of 5.5 years of follow-up CONCLUSIONS This trial of adjuvant chemotherapy in completely resected patients with unfavorable characteristics demonstrates apparent improvement in outcome compared to historical series treated with surgery alone. However, the results of this trial and other randomized trials of HAI do not appear to support its use at this time due to the development of more effective systemic options. PMID:21729678

    HIV-associated Kaposi sarcoma (HIV-KS) is the most common cancer in Malawi. In 2008, the non-governmental organization, Partners In Health, and the Ministry of Health established the Neno Kaposi Sarcoma Clinic (NKSC) to treat HIV-KS in rural Neno district. We aimed to evaluate 12-month clinical outcomes and retention in care for HIV-KS patients in the NKSC, and to describe our implementation model, which featured protocol-guided chemotherapy, integrated antiretroviral therapy (ART) and psychosocial support delivered by community health workers. We conducted a retrospective cohort study using routine clinical data from 114 adult HIV-KS patients who received ART and ≥1 chemotherapy cycle in the NKSC between March 2008 and February 2012. At enrolment 97% of patients (n/N=103/106) had advanced HIV-KS (stage T1). Most patients were male (n/N=85/114, 75%) with median age 36 years (interquartile range, IQR: 29-42). Patients started ART a median of 77 days prior to chemotherapy (IQR: 36-252), with 97% (n/N=105/108) receiving nevirapine/lamivudine/stavudine. Following standardized protocols, we treated 20 patients (18%) with first-line paclitaxel and 94 patients (82%) with bleomycin plus vincristine (BV). Of the 94 BV patients, 24 (26%) failed to respond to BV requiring change to second-line paclitaxel. A Division of AIDS grade 3/4 adverse event occurred in 29% of patients (n/N=30/102). Neutropenia was the most common grade 3/4 event (n/N=17/102, 17%). Twelve months after chemotherapy initiation, 83% of patients (95% CI: 74-89%) were alive, including 88 (77%) retained in care. Overall survival (OS) at 12 months did not differ by initial chemotherapy regimen (p=0.6). Among patients with T1 disease, low body mass index (BMI) (adjusted hazard ratio, aHR=4.10, 95% CI: 1.06-15.89) and 1 g/dL decrease in baseline haemoglobin (aHR=1.52, 95% CI: 1.03-2.25) were associated with increased death or loss to follow-up at 12 months.

    Indwelling pleural catheters (IPC) are increasingly becoming a first-line treatment in the management of malignant pleural effusions. Ambulatory management using IPC are increasingly used in this patient group whilst they are receiving concurrent chemotherapy. There are currently no prospective trials examining IPC safety in chemotherapy. This study's objective is to determine if IPC insertion is safe in patients undergoing chemotherapy. We conducted a retrospective analysis of all patients who underwent IPC insertion for malignant pleural effusion at our trust from September 2010 to December 2014. Data was collected on IPC insertion and removal, tumour type, systemic chemotherapy, pleural infection and other complications. One hundred four patients were identified, 43 in chemotherapy group and 61 in non-chemotherapy group. The incidence of pleural infection in chemotherapy group vs non-chemotherapy group, 4 (9.3%) vs 3 (4.9%) respectively, was not statistically different (Fisher's exact p = 0.311). There was no significant difference in six-month infection-free duration from the date of IPC insertion (log rank p = 0.394). Overall six-month mortality in chemotherapy group was significantly lower than in non-chemotherapy group (log rank p = 0.007). This is the second largest retrospective case-control series that concludes systemic chemotherapy is safe in patients with IPC undergoing chemotherapy.

    Few dermatologic conditions carry as much emotional distress as chemotherapy-induced alopecia (CIA). The prerequisite for successful development of strategies for CIA prevention is the understanding of the pathobiology of CIA. The incidence and severity of CIA are variable and related to the particular chemotherapeutic protocol. CIA is traditionally categorized as acute diffuse hair loss caused by dystrophic anagen effluvium; however, CIA presents with different clinical patterns of hair loss. When an arrest of mitotic activity occurs, obviously numerous and interacting factors influence the shedding pattern. The major approach to minimize CIA is by scalp cooling. Unfortunately, most published data on scalp cooling are of poor quality. Several experimental approaches to the development of pharmacologic agents are under evaluation and include drug-specific antibodies, hair growth cycle modifiers, cytokines and growth factors, antioxidants, inhibitors of apoptosis, and cell-cycle and proliferation modifiers. Ultimately, the protection should be selective to the hair follicle; for example, topical application, such that the anticancer efficacy of chemotherapy is not hampered. Among the few agents that have been evaluated so far in humans, AS101 and minoxidil were able to reduce the severity or shorten the duration of CIA, but could not prevent CIA.

    There are many reasons that lead to failure of cancer chemotherapy. Cancer has the ability to become resistant to many different types of drugs. Increased efflux of drug, enhanced repair/increased tolerance to DNA damage, high antiapoptotic potential, decreased permeability and enzymatic deactivation allow cancer cell survive the chemotherapy. Treatment can lead to the death of most tumor cells (drug-sensitive), but some of them (drug-resistant) survive and grow again. These tumor cells may arise from stem cells. There are many studies describing human experiments with multidrug resistance, especially in breast cancer. Unfortunately, studies of canine or feline ABC super family members are not as extensive as in human or mice and they are limited to several papers describing PGP in mammary cancer, cutaneous mast cell tumors and lymphoma. Multidrug resistance is one of the most significant problems in oncology today. The involvement of many different, not fully recognized, mechanisms in multidrug resistance of cancer cells makes the development of effective methods of therapy very difficult. Understanding the mechanisms of drug resistance in cancer cells may improve the results of treatment. This review article provides a synopsis of all aspects that refer to cancer cell resistance to antitumor drugs.

    To assess the feasibility and the activity, as well as the efficacy to treat meninges, of chemotherapy (CHT) containing high-dose methotrexate (HD-MTX) followed by radiation therapy (RT), without intrathecal CHT, in patients with primary central nervous system lymphoma. Eligibility criteria were histologically proven diagnosis, disease limited to the CNS, age < or = 70, ECOG performance status < or = 3, HIV-negative and no prior treatment. Thirteen patients (1996-1999; median age 54 years) received two courses of vincristine 1.4 mg/m2 day 1, MTX 3 g/m2 days 3 and 10 and procarbazine 100 mg/m2 days 1-14 every 4 weeks. Patients who achieved a complete remission were referred to RT, those with progressive disease were excluded from further study; all the remaining patients received a third course of CHT followed by RT. Twelve patients responded to CHT (overall response rate = 92%, complete response rate = 77%): 9 underwent consolidation RT, 3 did not. Two patients experienced severe acute toxicity; lethal pulmonary thromboembolism and transient renal failure. Five patients relapsed: 2 after CHT and 3 after RT. Relapse was local in all cases, with a case of concomitant hepatic involvement. No cases of ocular or meningeal relapse were observed. In contrast to high-dose cytarabine-containing CHT, salvage therapy with temozolomide produced good results. Two patients died of treatment-related neurotoxicity. Six patients are alive with a median follow-up of 17 months, and a 2-year overall survival (OS) of 61%. The median survival of the 9 patients who completed the planned treatment is 25+ months with a 2-year OS of 80%. HD-MTX, procarbazine and vincristine followed by RT, without intrathecal therapy, produce similar results with respect to other HD-MTX-containing regimens. These results seem to suggest that adequate meningeal treatment is possible without intrathecal drug delivery, even in CSF-positive patients. Corroborating data from a larger series are, however

    Purpose. The purpose of this study was to compare intrahepatic and pancreatic perfusion on fusion images using a combined single-photon emission computed tomography (SPECT)/CT system and to evaluate the efficacy of combined continuous transcatheter arterial infusion (CTAI) and systemic chemotherapy in the treatment of advanced pancreatic carcinoma. Materials and Methods. CTAI was performed in 33 patients (22 men, 11 women; age range, 35-77 years; mean age, 60 years) with stage IV pancreatic cancer with liver metastasis. The reservoir was transcutaneously implanted with the help of angiography. The systemic administration of gemcitabine was combined with the infusion of 5-fluorouracil via the reservoir. In all patients we obtained fusion images using a combined SPECT/CT system. Pancreatic perfusion on fusion images was classified as perfusion presence or as perfusion absent in the pancreatic cancer. Using WHO criteria we recorded the tumor response after 3 months on multislice helical CT scans. Treatment effects were evaluated based on the pancreatic cancer, liver metastasis, and factors such as intrahepatic and pancreatic perfusion on fusion images. For statistical analysis we used the chi-square test; survival was evaluated by the Kaplan Meier method (log-rank test). Results. On fusion images, pancreatic and intrahepatic perfusion was recorded as hot spot and as homogeneous distribution, respectively, in 18 patients (55%) and as cold spot and heterogeneous distribution, respectively, in 15 (45%). Patients with hot spot in the pancreatic tumor and homogeneous distribution in the liver manifested better treatment results (p < 0.05 and p < 0.01, respectively). Patients with hot spot both in the pancreatic cancer and in the liver survived longer than those with cold spot in the pancreatic cancer and heterogeneous distribution in the liver (median {+-} SD, 16.0 {+-} 3.7 vs. 8.0 {+-} 1.4 months; p < 0.05). Conclusions. We conclude that in patients with advanced

    A 53-year-old male presented with a chief complaint of dyschezia.Lower gastrointestinal endoscopy confirmed the presence of a type II tumor in the lower part of the rectum, and a biopsy detected a well-differentiated adenocarcinoma.As invasion of the prostate and levator muscle of the anus was suspected on diagnostic imaging, surgery was performed after preoperative chemotherapy.With no clear postoperative complications, the patient was discharged 26 days after surgery. After 24 months, the number of urination ranged from 1 to 6, with a Wexner score of 6 and a mild desire to urinate in the absence of incontinence.At present, the patient is alive without recurrence.When combined with chemotherapy, robotassisted surgery allows the curative resection of extensive rectal cancer involving the suspected invasion of other organs.In this respect, it is likely to be a useful method to conserve anal and bladder function.

    Ovarian cancer leads to abdominal carcinomatosis and late stage (III/IV) diagnosis in 75% of patients. Three randomized phase III trials have demonstrated that intraperitoneal (IP) chemotherapy improves outcomes in epithelial ovarian cancer. While IP treatment is validated by clinical trials, there is a poor understanding of the mechanism(s) leading to the survival advantage other than the increased concentration of cytotoxic drugs within the tumor microenvironment. A better understanding of this process through analysis of dynamic biomarkers should promote novel approaches that may enhance tumor clearance. We propose this pilot study to confirm the feasibility of collecting serial peritoneal samples from implanted catheters in women receiving IP chemotherapy. We believe these specimens may be used for multiplex analysis to reveal unique biomarker fluctuations when compared to peripheral blood. From 13 women participating on GOG 252, 30 whole blood, 12 peritoneal fluid (PF), and 20 peritoneal wash (PW) with 30mL saline were obtained. Samples were requested prior to the first three chemotherapy cycles. Samples were assessed for volume, cell populations, protein, RNA, and miRNA content changes. Median volume for PF was 1.6mL and 3.1mL for PW. PW is a dilution of PF capable of capturing measurable biomarkers. Peritoneal aspirates contain a unique profile of biomarkers distinct from blood. miRNA undergo earlier alteration with chemotherapy than genes. Flow cytometry does not adequately capture biomarker fluctuations. As a proof of principle study, this trial provides evidence that sampling the peritoneal cavity can be adapted for biomarker analysis. Copyright © 2017 Elsevier Inc. All rights reserved.

    The calpains are a family of intracellular cysteine proteases that function in a variety of important cellular functions, including cell signalling, motility, apoptosis and survival. In early invasive breast cancer expression of calpain-1, calpain-2 and their inhibitor, calpastatin, have been associated with clinical outcome and clinicopathological factors.The expression of calpain-1, calpain-2 and calpastatin was determined using immunohistochemistry on core biopsy samples, in a cohort of large but operable inflammatory and non-inflammatory primary breast cancer patients treated with neoadjuvant chemotherapy. Information on treatment and prognostic variables together with long-term clinical follow-up was available for these patients. Diagnostic pre-chemotherapy core biopsy samples and surgically excised specimens were available for analysis.Expression of calpastatin, calpain-1 or calpain-2 in the core biopsies was not associated with breast cancer specific survival in the total patient cohort; however, in patients with non-inflammatory breast cancer, high calpastatin expression was significantly associated with adverse breast cancer-specific survival (P=0.035), as was low calpain-2 expression (P=0.031). Low calpastatin expression was significantly associated with adverse breast cancer-specific survival of the inflammatory breast cancer patients (P=0.020), as was low calpain-1 expression (P=0.003).In conclusion, high calpain-2 and low calpastatin expression is associated with improved breast cancer-specific survival in non-inflammatory large but operable primary breast cancer treated with neoadjuvant chemotherapy. In inflammatory cases, high calpain-1 and high calpastatin expression is associated with improved breast cancer-specific survival. Determining the expression of these proteins may be of clinical relevance. Further validation, in multi-centre cohorts of breast cancer patients treated with neoadjuvant chemotherapy, is warranted.

  2. Palliative chemotherapy: oxymoron or misunderstanding?

    Oncologists routinely prescribe chemotherapy for patients with advanced cancer. This practice is sometimes misunderstood by palliative care clinicians, yet data clearly show that chemotherapy can be a powerful palliative intervention when applied appropriately. Clarity regarding the term "palliative chemotherapy" is needed: it is chemotherapy given in the non-curative setting to optimize symptom control, improve quality of life, and sometimes to improve survival. Unfortunately, oncologists lack adequate tools to predict which patients will benefit. In a study recently published in BMC Palliative Care, Creutzfeldt et al. presented an innovative approach to advancing the science in this area: using patient reported outcomes to predict responses to palliative chemotherapy. With further research, investigators may be able to develop predictive models for use at the bedside to inform clinical decision-making about the risks and benefits of treatment. In the meantime, oncologists and palliative care clinicians must work together to reduce the use of "end-of-life chemotherapy"-chemotherapy given close to death, which does not improve longevity or symptom control-while optimizing the use of chemotherapy that has true palliative benefits for patients.

    The use of chemotherapy to treat cancer began at the start of the 20th century with attempts to narrow the universe of chemicals that might affect the disease by developing methods to screen chemicals using transplantable tumors in rodents. It was, however, four World War II-related programs, and the effects of drugs that evolved from them, that provided the impetus to establish in 1955 the national drug development effort known as the Cancer Chemotherapy National Service Center. The ability of combination chemotherapy to cure acute childhood leukemia and advanced Hodgkin's disease in the 1960s and early 1970s overcame the prevailing pessimism about the ability of drugs to cure advanced cancers, facilitated the study of adjuvant chemotherapy, and helped foster the national cancer program. Today, chemotherapy has changed as important molecular abnormalities are being used to screen for potential new drugs as well as for targeted treatments.

    The delivery route of chemotherapy for intraocular retinoblastoma has become controversial. One objection to systemic delivery is the need for central venous access. We cross-referenced a hospital vascular access database with our tumor registry to determine the incidence of chemotherapy infiltrates. Sixty-five patients received 270 cycles of chemotherapy via peripheral intravenous access. Vincristine infiltration was 0% (95% confidence interval [CI] 0-0.16%) while that of non-vesicant chemotherapy was 0.7% (95%CI 0.1-2.6%). Giving chemotherapy via peripheral access to patients with retinoblastoma is safe. It can decrease therapy costs and prevent central line associated blood stream infections.

    Nurses are now primarily responsible for the provision of patient information, and the administration of an escalating number of cytotoxic agents. This paper aims to provide nurses with key information concerning the adverse effects of cytotoxic chemotherapy on the reproductive system of women of childbearing age. The provision of information on gonadal function and fertility is vital, particularly with the increase in the survival of women treated for cancer, and the trend towards women starting a family later in life. Gonadal toxicity of the various cytotoxic agents, disruption of the menstrual cycle, premature menopause, avoidance of pregnancy, chemotherapy in pregnancy, and fertility prospects post-chemotherapy are addressed in this paper.

    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

    2013-01-01

    The recent studies have evaluated the relationship between BRCA1 expression and clinical outcome of chemotherapy (mainly focused on platinum-based and toxal-based treatment) in NSCLC patients, but the results were inconclusive and controversial. Our aim of this study was to evaluate this association by literature based system review and meta-analysis. PubMed, EMBASE and the China National Knowledge Infrastructure (CNKI) databases were used to retrieve the relevant articles. The interested outcome included objective response rate (ORR), overall survival (OS) and event-free survival (EFS). The pooled odds ratio (OR) or hazard ratio (HR) with 95% confidence interval (CI) ware estimated. After specific inclusion and exclusion criteria, 23 studies fulfilled the criteria and were included in our analysis. In 17 platinum-based studies, low/negative BRCA1 was in favor of better ORR (OR = 1.70, 95%CI = 1.32-2.18), longer OS and EFS (HR = 1.58, 95%CI = 1.27-1.97, and HR = 1.60, 95%CI = 1.07-2.39 for OS and EFS, respectively). In 4 toxal-based chemotherapy studies, the patients with high/positive BRCA1 had better ORR (OR = 0.41, 95%CI = 0.26-0.64), OS and EFS were not evaluated as the insufficient data available. Overall, BRCA1 might be a useful biomarker to predict clinical outcome for personal chemotherapy in NSCLC patients in the future. PMID:23497550

    Neoadjuvant cisplatin-based combination chemotherapy is an established standard for resectable muscle-invasive bladder cancer, a disease with a pattern of predominantly distant and early recurrences. Pathologic complete remission appears to be an intermediate surrogate for survival when employing combination chemotherapy. Moreover, baseline host and tumor tissue studies may enable the discovery of biomarkers predictive of activity. The neoadjuvant setting also provides a window of opportunity to evaluate novel biologic agents or rational combinations of biologic agents to obtain a signal of biologic activity. The residual tumor after neoadjuvant therapy may be exploited to study the mechanism of action and resistance. Cisplatin-ineligible patients warrant the evaluation of tolerable neoadjuvant regimens. Given that bladder cancer is characterized by initial localized presentation in the vast majority of cases, the paradigm of neoadjuvant therapy may expedite the development of novel systemic agents.

    To combat the dismal mortality rates from metastatic gastric adenocarcinoma (GAC), new drugs and treatment strategies are needed. Today, metastatic GAC is predominantly treated by empiric chemotherapy. Combination of two cytotoxic agents has become commonplace in North America, Europe, and Asia. Human epidermal growth factor 2 (HER2) overexpression (protein or gene copy numbers) has resulted in the addition of trastuzumab in the first-line chemotherapy combination in patients whose tumor is HER2 positive. The addition of trastuzumab in this select population has provided a modest survival advantage. In this review we trace the global development of systemic therapy in patients with metastatic GAC and ponder what lies in the future.

    2016-12-01

    For women with oestrogen receptor+ metastatic breast cancer (MBC), the options for systemic treatment include endocrine therapy (ET) and chemotherapy. For women whose disease is also HER2+, anti-HER2 therapies are also routinely used either with chemotherapy or less commonly with ET. Where chemotherapy is used as initial therapy, treatment is often discontinued due to cumulative toxicity in the absence of disease progression. In this setting, there is the option of introducing ET with the aim of prolonging response and delaying relapse. Literature review revealed four trials addressing the question of whether there is a benefit from introducing ET following chemotherapy for MBC. We also sought evidence for alternative approaches, including concurrent chemotherapy and ET and continuing chemotherapy until disease progression. The evidence for the use of ET after chemotherapy in MBC is limited, and the trials done were small. Furthermore, they were performed at a time when both the chemotherapy regimens and ET were different from those used currently. Despite these limitations, there is probably a modest improvement in time to progression for the sequential use of ET after chemotherapy but with no overall survival benefit. An alternative approach, particularly considering agents with relatively low toxicity, such as orally bioavailable fluoropyrimidines, is to continue chemotherapy until disease progression. Where chemotherapy for MBC is discontinued due to toxicity, in the absence of progression, the use of ET, with its relatively low toxicity, is a reasonable approach with the aim of delaying relapse.

    2017-04-01

    The management of tuberculosis (TB) can be a challenging process that has implications both for the affected patient and public health. Effective anti-TB chemotherapy both cures and renders the patient noncontagious. Biological factors specific to M. tuberculosis necessitate the use of multiple drugs for prolonged durations to adequately eradicate infection. Recommended regimens address the complexities of eliminating organisms from diverse reservoirs while preventing the emergence of drug resistance. First-line anti-TB therapy for drug susceptible disease effectively cures almost all patients within 6-9 months. The loss of first-line agents, due to resistance or intolerance, necessitates lengthy treatment courses, frequently 12-18 months or longer. Due to the long treatment times and the implications of missed doses, directly-observed therapy (DOT) is considered the standard of care. Drugs used for the treatment of TB have serious potential toxicities that require close monitoring and prompt response. A strong public health infrastructure and robust social supports are important elements to assure successful treatment. These numerous factors compel public health entities to take a lead role in the management of TB, either through the direct management of TB treatment or by assuring the activities of partner organizations.

    Melanoma is a most dangerous and deadly type of skin cancer, and considered intrinsically resistant to both radiotherapy and chemotherapy. It has become a major public health concern as the incidence of melanoma has been rising steadily over recent decades with a 5-year survival remaining less than 5%. Detection of the disease in early stage may be curable, but late stage metastatic disease that has spread to other organs has an extremely poor prognosis with a median survival of less than 10 months. Since metastatic melanoma is unresponsive to therapy that is currently available, research is now focused on different treatment strategies such as combinations of surgery, chemotherapy and radiotherapy. The molecular basis of resistance to chemotherapy seen in melanoma is multifactorial; defective drug transport system, altered apoptotic pathway, deregulation of apoptosis and/or changes in enzymatic systems that mediate cellular metabolic machinery. Understanding of alterations in molecular processes involved in drug resistance may help in developing new therapeutic approaches to treatment of malignant melanoma. PMID:28382191

    The 30-45% failure rate after radical cystoprostatectomy mandates that we explore and optimize multimodal therapy to achieve better disease control in these patients. Cisplatin-based multi-agent combination chemotherapy has been used with success in metastatic disease and has therefore also been introduced in patients with high-risk but non-metastatic bladder cancer. There is now convincing evidence that chemotherapy given pre-operatively can improve survival in these patients. In this review we establish the need for peri-operative chemotherapy in bladder cancer patients and summarize the evidence for the efficacy of neoadjuvant chemotherapy. The advantages and disadvantages of neoadjuvant versus adjuvant chemotherapy are discussed, and the main shortcomings of both--treatment-related toxicity and the inability to prospectively identify likely responders--are presented. Finally, a risk-adapted approach to neoadjuvant chemotherapy is presented, whereby the highest risk patients are offered treatment while those unlikely to benefit are spared the treatment-related toxicity.

    It is well known that tumor formation arises from the imbalance between cell death and proliferation. For many years, cancer research has engaged an important part of its efforts to find new therapeutic strategies based on cell death induction. One of the predominant ways to kill tumor cells is to trigger apoptosis by chemotherapy. However tumor responsiveness to chemotherapy is dependent on different biological factors including cancer types, genetics and pharmacogenetics. Although molecular mechanisms involved in chemotherapy-induced apoptosis are diverse and depend on cell-type and drugs used, a common pathway leading to tumor cell death has been shown to implicate the generation of a simple cellular sphingolipid, ceramide. Ceramide is released by the activity of neutral or acidic sphingomyelinases or de novo synthesis during treatment with chemotherapy. This review in particular focuses on enzymes involved in chemotherapy-induced cell death such as neutral or acidic sphingomyelinases and ceramide synthases, the role of ceramide in cellular effects of chemotherapy at the plasma membrane or the mitochondria and the induction of cell death by ceramide. It also includes recent advances on novel patented sphingolipid compounds and cancer therapeutic strategies based on ceramide release.

There are promising results and randomized trials are needed in patients with a metastatic cholangiocarcinoma. In systemic therapy, no single drug or combination has consistently increased median survival beyond the expected 8-12 mo. It is always recommended that patients enrol in clinical trials. Clinical trials have shown that the more standard chemotherapy for a first line regimen of gemcitabine plus cisplatin (or oxaliplatin as a potentially better tolerated agent) is superior to gemcitabine alone. Leucovorin-modulated 5-fluorouracil, capecitabine monotherapy or single agent gemcitabine are reasonable options for patients with a borderline performance status. After progression in patients with an adequate performance status, active regimens that could be considered include gemcitabine plus capecitabine, or erlotinib plus bevacizumab, for second line treatment.

    Patients with advanced non-small cell lung cancer (NSCLC) generally require second-line treatment although their prognosis is poor. In this multicenter study, we aimed to detect the characteristics related to patients and disease that can predict the response to second-line treatments in advanced NSCLC. Data of 904 patients who have progressed after receiving first-line platinum-based chemotherapy in 11 centers with the diagnosis of stage IIIB and IV NSCLC and who were evaluated for second-line treatment were retrospectively analyzed. The role of different factors in determining the benefit of second-line treatment was analyzed. Median age of patients was 57 years (range 19-86). Docetaxel was the most commonly used (20.9 %, n = 189) single agent, while gemcitabine-platinum was the most commonly used (6.7 %, n = 61) combination chemotherapy regimen in second-line setting. According to survival analysis, median progression-free survival after first-line treatment (PFS2) was 3.5 months (standard error (SE) 0.2; 95 % confidence interval (CI), 3.2-3.9), median overall survival (OS) was 6.7 months (SE 0.3; 95 % CI, 6.0-7.3). In multivariate analysis, independent factors affecting PFS2 were found to be hemoglobin (Hb) level over 12 g/dl and treatment-free interval (TFI) longer than 3 months (p = 0.006 and 0.003, respectively). Similarly, in OS analysis, Hb level over 12 g/dl and time elapsed after the first-line treatment that is longer than 3 months were found to be independent prognostic factors (p = 0.0001 and 0.045, respectively). In light of these findings, determining and using the parameters for which the treatment will be beneficial prior to second-line treatment can increase success rate.

    From the therapuetic point of view, non-Hodgkin's lymphomas can be classified into two groups: favourable prognosis histology (DWDL, NWDL, NPDL, and NM) and unfavourable prognosis histology (DPDL, DM, DH, NH, DU). The latter group also includes lymphoblastic lymphoma (T cell) and Burkitt's lymphoma (B cell). Further classification by immunological markers (T, B, monocyte, null cell) and functional categories (T-cell subsets) may reveal prognostic groups which require separate consideration. Intensive chemotherapy of unfavourable histoligies can result in long-term disease-free survival as reported in several series. It would appear that the 10 year survival rates will not differ greatly between several multi-drug regimens. At the present time, the histopathological subtype permits selection of patients for a trial of intensive chemotherapy. The progress in the future will be made with improved techniques for the management of bulky abdominal disease and central nervous system invasion. Although the above may result in some statistical improvement in survival of the unfavourable group, the vast majority of patients with favourable histology lymphoma require new approaches. These may take the form of treatment with immunological manoeuvres such as idiotypic-specific antibodies and/or the use of intensive chemotherapy, especially when there is convincing evidence of a change in the biology of the disease.

    Several changes in the oral cavity due to chemotherapy can be observed and can lead to important systemic complications, increasing the time of the patient in hospital and the costs of the treatment as well as affect the quality of life of the patients. The aim of this study was to assess the oral manifestation in patients treated with chemotherapy according to sex, age and tumor type. Data was collected in an oncology hospital in Juiz de Fora, Minas Gerais State, from patients' records that were submitted to oncologic treatment. It was possible to verify that mucositis, associated or not to other type of lesions, was the most common lesion in both sex of all ages (15.5%). Xerostomia and other lesions, such as Candida infection and aphthous lesions, were also present. It is possible to improve the quality of life of the patient during and after anti-neoplastic therapies through a protocol of odontological assistance that includes changes of the oral environment previous to chemotherapy such as profilaxis, caries removal, treatment of periodontal and periapical lesions, oral hygiene instructions, diet orientation and laser therapy. It is very important the insertion of the dentist in the oncologic medical team for the early diagnosis of the oral manifestation and follow-up during treatment time.

    Cancer is one of the most prevalent disease processes affecting people of all ages. Cancer is the second most common cause of death in the United States, exceeded only by heart disease. Cancer survival is dependent on treatment options that may include surgery, radiation, and chemotherapy. Chemotherapy, or systemic cancer therapy, is designed to promote cell death during different phases of cell growth and division. Unfortunately, chemotherapeutic agents cannot differentiate between malignant and normal cells. Therefore, the toxic effects of chemotherapy are also seen in healthy organs and tissues. In addition, chemotherapeutic agents can interact with other medications. The effects of chemotherapy may be acute and self-limiting or chronic and present long after treatment has been completed. Patients who have had chemotherapy often undergo surgery that may or may not be related to their cancer. Chemotherapy administration can have a profound influence on anesthetic management. Safe administration of anesthesia includes knowledge of chemotherapeutic agents and their toxic effects. This course discusses the anatomic and physiologic effects of cancer chemotherapeutic agents and how they specifically affect patients receiving anesthesia.

    Although side effects of cancer chemotherapy are well known, "opposite effects" of chemotherapy which enhance the malignancy of the treated cancer are not well understood. We have observed a number of steps of malignancy that are enhanced by chemotherapy pre-treatment of mice before transplantation of human tumor cells. The induction of intravascular proliferation, extravasation, and colony formation by cancer cells, critical steps of metastasis was enhanced by pretreatment of host mice with the commonly-used chemotherapy drug cyclophosphamide. Cyclophosphamide appears to interfere with a host process that inhibits intravascular proliferation, extravasation, and extravascular colony formation by at least some tumor cells. Cyclophosphamide does not directly affect the cancer cells since cyclophosphamide has been cleared by the time the cancer cells were injected. Without cyclophosphamide pretreatment, human colon cancer cells died quickly after injection in the portal vein of nude mice. Extensive clasmocytosis (destruction of the cytoplasm) of the cancer cells occurred within 6 hours. The number of apoptotic cells rapidly increased within the portal vein within 12 hours of injection. However, when the host mice were pretreated with cyclophosphamide, the cancer cells survived and formed colonies in the liver after portal vein injection. These results suggest that a cyclophosphamide-sensitive host cellular system attacked the cancer cells. This review describes an important unexpected "opposite effects" of chemotherapy that enhances critical steps in malignancy rather than inhibiting them, suggesting that certain current approaches to cancer chemotherapy should be modified.

  3. Oral toxicity produced by chemotherapy: A systematic review

    2014-01-01

    Introduction: Antineoplastic chemotherapy remains one of the most widely used management strategies in cancer, either alone or in combination with other types of treatment. The main inconvenience of chemotherapy is its lack of selectivity, since it acts upon both tumor cells and rapidly multiplying normal cells such as bone marrow cells, hair follicle cells and oral and gastrointestinal mucosal cells. Material and method: An exhaustive search was made of the main oral toxic effects of chemotherapy in the PubMed-Medline, Cochrane Library and Scopus databases. A total of 1293 articles were identified, of which 333 met the study inclusion criteria. Results: The toxic effects of chemotherapy at oral mucosal level comprise mucositis, osteonecrosis of the jaws secondary to bisphosphonate use, susceptibility to infections, dental alterations, salivary and neurological disorders, dysgeusia and bleeding tendency. These complications have a negative impact upon patient quality of life, and in some cases can prove life-threatening. Conclusions: Evaluation of patient oral and dental health is essential before administering chemotherapy, in order to minimize the risk of oral and systemic complications of such treatment. Key words:Chemotherapy, oral complications, dental, saliva and osteonecrosis jaw. PMID:24596641

    GATA-3 and estrogen receptor (ER) are involved in a positive cross-regulatory loop and are frequently coexpressed in breast cancers. GATA-3 expression was shown to be an independent predictor of overall and disease-free survival in some studies, whereas others showed no difference. However, the studies used different cutoff values for determining GATA-3 positivity and analyzed outcomes in patients who received systemic therapy together with those who did not. We investigated GATA-3 expression and correlated clinicopathologic findings and outcomes in 516 women who received systemic chemotherapy and/or hormonal therapy. Nuclear staining of 1% or greater was considered positive for GATA-3, ER and progesterone receptor (PR). Of 516 cases, 436 (84.5%) were GATA-3+. GATA-3+ tumors were more likely to be grade 1 or 2, ER+, PR+, non-triple-negative phenotypes (all P < .0001), and higher stage (P = .01). ER-/GATA-3+ tumors, compared with ER-/GATA-3- tumors, had worse breast cancer survival (BCS) (P = .02) and a trend for worse overall survival (OS) (P = .05) in univariate analysis. However, there was no difference in OS and BCS between patients who received chemotherapy and/or hormonal therapy among GATA-3-positive and GATA-3-negative groups. GATA-3+ tumors are correlated with lower grade, ER+, PR+, and non-triple-negative phenotypes. Although there was no difference in OS and BCS between GATA-3-positive and GATA-3-negative groups, there was an adverse effect of GATA-3 expression in the ER-negative subgroup of patients who received systemic therapy.

    Two trends in breast cancer management - less radical local treatment and more radical systemic treatment - are conjoined when one considers the use of adjuvant chemotherapy in patients treated by primary radiation therapy. This editorial discusses a number of important issues regarding this combination of treatments. The most important issue is whether the survival results of combined radiation and chemotherapy are equivalent to those obtained with mastectomy and chemotherapy.

    Epithelial ovarian cancer remains the most lethal gynecologic malignancy despite advances in treatment. The standard management generally involves a combination of surgical tumor debulking and chemotherapy. Over the decades, chemotherapy for ovarian cancer has evolved and currently involves a combination of intravenous platinum and taxane chemotherapy. Over the past decade, three randomized phase III trials have been reported, and all have demonstrated a significant survival advantage for intraperitoneal compared with intravenous chemotherapy. However, there are potential barriers and controversies related to the administration of intraperitoneal chemotherapy in ovarian cancer patients. In this review, we discuss the evolution and current management considerations of chemotherapy for the treatment of epithelial ovarian cancer. PMID:21789133

  7. Sphingolipids and response to chemotherapy.

    2013-01-01

    Chemotherapy is frequently used to treat primary or metastatic cancers, but intrinsic or acquired drug resistance limits its efficiency. Sphingolipids are important regulators of various cellular processes including proliferation, apoptosis, differentiation, angiogenesis, stress, and inflammatory responses which are linked to various aspects of cancer, like tumor growth, neoangiogenesis, and response to chemotherapy. Ceramide, the central molecule of sphingolipid metabolism, generally mediates antiproliferative and proapoptotic functions, whereas sphingosine-1-phosphate and other derivatives have opposing effects. Among the variety of enzymes that control ceramide generation, acid or neutral sphingomyelinases and ceramide synthases are important targets to allow killing of cancer cells by chemotherapeutic drugs. On the contrary, glucosylceramide synthase, ceramidase, and sphingosine kinase are other targets driving cancer cell resistance to chemotherapy. This chapter focuses on ceramide-based mechanisms leading to cancer therapy sensitization or resistance which could have some impacts on the development of novel cancer therapeutic strategies.

    Carcinoma of the esophagus is classified according to the Union for International Cancer Control (UICC) TNM staging system. The 7th edition of the UICC TNM staging system was published in 2009. This is the first study to compare the prognostic value of the TNM 6th and 7th editions in patients with esophageal carcinoma treated with chemotherapy followed by surgery. Two hundred forty-three patients with esophageal carcinoma were retrospectively selected from two referral centers. All patients received chemotherapy before surgery. Histopathologic data from the resection specimens were retrieved and restaged according to the TNM 7th edition. Disease-specific survival curves were plotted for depth of tumor invasion (ypT), lymph node status (ypN), and ypTNM stage and then compared. Median follow-up after surgery was 2.5 years (range 0.2-9 years). Survival analysis using the log-rank method revealed that there was a significant difference in survival between ypT4 disease and ypT3 disease (P= 0.003), but no difference between ypT0, ypT1, ypT2, and ypT3 categories irrespective of TNM edition used. Survival probability was significantly different between ypN0 and ypN1 (P= 0.001 for TNM 6th and 7th edition), as well as ypN2 and ypN3 (TNM 7th edition, P= 0.004), but not between ypN1 and ypN2 (TNM 7th edition, P= 0.89). Neither the TNM 6th nor 7th edition T staging provides accurate survival probability stratification. However, the advantage of the 7th edition is the introduction of a third tier in survival stratification for patients with nodal involvement. © 2012 Copyright the Authors.

  9. Understanding resistance to combination chemotherapy.

    The current clinical application of combination chemotherapy is guided by a historically successful set of practices that were developed by basic and clinical researchers 50-60 years ago. Thus, in order to understand how emerging approaches to drug development might aid the creation of new therapeutic combinations, it is critical to understand the defining principles underlying classic combination therapy and the original experimental rationales behind them. One such principle is that the use of combination therapies with independent mechanisms of action can minimize the evolution of drug resistance. Another is that in order to kill sufficient cancer cells to cure a patient, multiple drugs must be delivered at their maximum tolerated dose - a condition that allows for enhanced cancer cell killing with manageable toxicity. In light of these models, we aim to explore recent genomic evidence underlying the mechanisms of resistance to the combination regimens constructed on these principles. Interestingly, we find that emerging genomic evidence contradicts some of the rationales of early practitioners in developing commonly used drug regimens. However, we also find that the addition of recent targeted therapies has yet to change the current principles underlying the construction of anti-cancer combinatorial regimens, nor have they made substantial inroads into the treatment of most cancers. We suggest that emerging systems/network biology approaches have an immense opportunity to impact the rational development of successful drug regimens. Specifically, by examining drug combinations in multivariate ways, next generation combination therapies can be constructed with a clear understanding of how mechanisms of resistance to multi-drug regimens differ from single agent resistance.

    The aim of this study was to investigate the correlation between the expression of S100A4 and the efficacy of neoadjuvant chemotherapy in breast cancer. A total of 65 patients with invasive breast cancer were treated with neoadjuvant chemotherapy using the TAC regimen. The expression of S100A4 was detected by an immunohistochemical two-step method prior to treatment, after 2 cycles of chemotherapy and after 4 cycles of chemotherapy. Pathological evaluations of the chemotherapy were performed using the Miller and Payne (MP) grading system and their correlation with the changes of S100A4 expression during and after the treatment were explored. Between pre-neoadjuvant chemotherapy and 4 cycles post-chemotherapy, there was a significant difference in the expression of S100A4 (P<0.05); S100A4 expression was associated with neoadjuvant chemotherapy. However, between pre-neoadjuvant chemotherapy and 2 cycles post-chemotherapy, there was no significant difference in the expression of S100A4 (P>0.05). The intensity and changes of S100A4 expression were positively correlated with the efficacy of neoadjuvant chemotherapy (r=0.259, P<0.05). When patients with an MP grade of I or II following the second cycle of neoadjuvant chemotherapy were continually treated with the original chemotherapy for another 2 cycles, the desired effect was generally not achieved. S100A4 may be used as a predictor of the efficacy of neoadjuvant chemotherapy in breast cancer, guiding the formulation of individualized programs to improve the effectiveness of the treatment. For patients with an MP grade level of I or II after 2 cycles of neoadjuvant chemotherapy, the use of alternative chemotherapy regimens should be considered.

    Most patients with non-small cell lung cancer (NSCLC) present with advanced disease requiring systemic chemotherapy. Treatment with the antiangiogenic agent bevacizumab in combination with standard platinum-based doublet chemotherapy has been shown to improve outcomes in patients with advanced NSCLC. Several multitargeted antiangiogenic tyrosine kinase inhibitors (e.g., sorafenib, sunitinib, cediranib, vandetanib, BIBF 1120, pazopanib, and axitinib) are also being evaluated in combination with standard chemotherapy. Here we review current clinical data with combination therapy involving antiangiogenic agents and cytotoxic chemotherapy in patients with advanced NSCLC. PMID:21469981

    Identifying sources of variability in the response to cancer chemotherapy requires knowledge of all variables including concomitant medications, which can alter metabolism and pharmacokinetics of chemotherapy. This study investigated the accuracy of concomitant medication lists in the charts of cancer patients. Collated information from a questionnaire, patient interview and patient’s medical chart were used to obtain validated medication lists. Patients took an average of 4.8 prescription drugs, 1.6 non-prescription drugs and 1.6 other remedies within three days prior to chemotherapy. Medical records did not report 24% of prescription drugs, 84% of non-prescription drugs and 83% of other remedies. Electronic medical records were more complete than paper charts, but failed to report more than 75% of non-prescription drugs and other remedies. Potential drug interactions were noted. This study documents the extent and complexity of concomitant drugs taken by patients undergoing chemotherapy and the deficiencies in recording this information in medical charts. PMID:21124312

  15. Chemotherapy-induced hair loss.

    2010-01-01

    Chemotherapy-induced hair loss occurs with an estimated incidence of 65%. Forty-seven percent of female patients consider hair loss to be the most traumatic aspect of chemotherapy and 8% would decline chemotherapy due to fears of hair loss. At present, no approved pharmacologic intervention exists to circumvent this side-effect of anticancer treatment, though a number of agents have been investigated on the basis of the current understanding of the underlying pathobiology. Among the agents that have been evaluated, topical minoxidil was able to reduce the severity or shorten the duration, but it did not prevent hair loss. The major approach to minimize chemotherapy-induced hair loss is by scalp cooling, though most published data on this technique are of poor quality. Fortunately, the condition is usually reversible, and appropriate hair and scalp care along with temporarily wearing a wig may represent the most effective coping strategy. However, some patients may show changes in color and/or texture of regrown hair, and in limited cases the reduction in density may persist.

    The aim of this study is to examine treatment patterns for chemotherapy-induced anemia (CIA) between calendar periods when the changes in the US prescribing information, for erythropoiesis-stimulating agents (ESAs) took place. Patients diagnosed with breast, lung, colorectal, ovarian, or gastric cancer (2000-2012) who developed grade 2+ CIA (hemoglobin (Hb) <10 g/dl) were identified from Kaiser Permanente Southern California Health Plan. We estimated the proportions of CIA episodes with ESA use, red blood cell (RBC) transfusion, or prescription nutritional supplements in three calendar periods: January 1, 2000-December 31, 2006 (P1), January 1, 2007-March 24, 2010 (P2), and March 25, 2010-June 30, 2013 (P3). Multivariable regressions were used to test the differences of CIA treatment approaches and Hb concentration prior to CIA treatment across these calendar periods. The proportions of CIA episodes with ESA use were 28 % in P1, 21 % in P2, and 3 % in P3. For RBC transfusion, they were 8 % in P1, 14 % in P2 and 16 % in P3. The trend of decreasing ESA use and increasing transfusion use were statistically significant. Relative to P1, the odds ratio (OR) was 0.69 (95% CI: 0.55, 0.86) for P2 and 0.08 (0.30, 0.88) for P3 for ESA use. For RBC transfusion, OR was 2.00 (1.56, 2.56) for P2 and 2.37 (1.88, 3.00) for P3. Use of prescription nutritional supplement was rare across calendar periods. There was a decreasing trend of Hb concentration prior to ESA use (p value <0.01), but no difference in Hb concentrations prior to transfusion. In the management of CIA, use of ESA has decreased over time, while use of RBC transfusion has increased.

    Purpose: The aim of this Phase II study was to examine whether concurrent continuous infusion 5-fluorouracil (CI 5FU) plus three-dimensional conformal planning radiotherapy sandwiched between gemcitabine chemotherapy is effective, tolerable, and safe in the management of pancreatic cancer. Methods and Materials: Patients were enrolled in two strata: (1) resected pancreatic cancer at high risk of local relapse (postsurgery arm, n = 22) or (2) inoperable pancreatic cancer in head or body without metastases (locally advanced arm, n = 41). Gemcitabine was given at 1,000 mg/m{sup 2} weekly for 3 weeks followed by 1 week rest then 5-6 weeks of radiotherapy and concurrent CI 5FU (200 mg/m{sup 2}/day). After 4 weeks' rest, gemcitabine treatment was reinitiated for 12 weeks. Results: For the two arms combined, treatment-related Grade 3 and 4 toxicities were reported by 25 (39.7%) and 7 (11.1%) patients, respectively. No significant late renal or hepatic toxicity was observed. In the postsurgery arm (R1 54.5%), median time to progressive disease from surgery was 11.0 months, median time to failure of local control was 32.9 months, and median survival time was 15.6 months. The 1- and 2-year survival rates were 63.6% and 31.8%. No significant associations between outcome and mutations in K-ras or TP53 or microsatellite instability were identified. Post hoc investigation of cancer antigen 19-9 levels found baseline levels and increases postbaseline were associated with shorter survival (p = 0.0061 and p < 0.0001, respectively). Conclusions: This three-dimensional chemoradiotherapy regimen is safe and promising, with encouraging local control for a substantial proportion of patients, and merits testing in a randomized trial.

    Deeply invasive bladder cancer, representing approximately 20% of incident cases, is cured by radical cystectomy or radiotherapy in less than 50% of cases. In an effort to improve cure rates, based on objective response rates in metastatic disease of 40%-70% from combination chemotherapy regimens, systemic chemotherapy has been incorporated into programs of definitive treatment for this disease. Several randomized trials and a meta-analysis have confirmed a survival benefit from neoadjuvant chemotherapy followed by definitive local treatment, reflecting both median survival figures and cure rates. Despite several promising phase II trials, no randomized trial of classical adjuvant chemotherapy for bladder cancer has demonstrated an overall survival benefit, despite increments in disease-free survival. Molecular prognostication has been studied in an effort to improve the utility of systemic therapy for invasive non-metastatic bladder cancer, but randomized trials have not shown associated survival benefit. Despite level 1 evidence of a survival benefit from neoadjuvant MVAC (methotrexate, vinblastine, doxorubicin [Adriamycin], cisplatin) or cisplatin, methotrexate, and vinblastine (CMV) chemotherapy, more than 50% of incident cases do not receive such treatment.

    The present study evaluated the feasibility and effectiveness of myeloablative high-dose chemotherapy and autologous stem cell transplantation in patients with relapsed or progressed central nervous system germ cell tumors (CNS-GCTs). Eleven patients with non-germinomatous germ cell tumors and nine patients with germinomas were enrolled. Patients received between two and eight cycles of conventional chemotherapy prior to HDCT/autoSCT with or without radiotherapy. Overall, 16 patients proceeded to the first HDCT/autoSCT, and nine proceeded to the second HDCT/autoSCT. CTE (carboplatin-thiotepa-etoposide) and cyclophosphamide-melphalan (CM) regimens were used for the first and second HDCT, respectively. Toxicities during HDCT/autoSCT were acceptable, and there were no treatment-related deaths. Twelve patients experienced relapse or progression; however, four patients with germinomas remain alive after subsequent RT. Therefore, a total of 12 patients (four NGGCTs and eight germinomas) remain alive with a median follow-up of 47 months (range 22-90) after relapse or progression. The probability of 3-year overall survival was 59.1 ± 11.2 % (36.4 ± 14.5 % for NGGCTs vs. 88.9 ± 10.5 % for germinomas, P = 0.028). RT, particularly craniospinal RT, was associated with a better tumor response prior to HDCT/autoSCT and a better final outcome. In conclusion, HDCT/autoSCT was feasible, and survival rates were encouraging. Further study with a larger cohort of patients is needed to elucidate the role of HDCT/autoSCT in the treatment of relapsed or progressed CNS-GCTs.

    2015-01-01

    Targeted therapy in retinoblastoma (RB) is widely accepted as the current management tool with an aim of increasing drug availability at the tumor location. Inevitably the effect is several times higher compared to systemic delivery of chemotherapeutic drugs and carries less systemic toxicity. Despite tremendous advancement in saving life, eye salvage in advanced RB especially with active vitreous seeds remains a challenge. The hypoxic environment of the vitreous and reduced vitreous concentration of the drugs delivered makes these tumor seeds resistant to chemotherapy. Direct delivery of chemotherapeutic drugs into the vitreous cavity aids to overcome these challenges and is progressively being accepted worldwide. However, intraocular procedure in RB was abandoned due to high risk of extraocular tumor dissemination. Recently, the forbidden therapeutic technique was re-explored and modified for safe use. Although eye salvage rate has tremendously improved after intravitreal chemotherapy (IVitC), retinal toxicity, and vision salvage are yet to be validated. In our preliminary report of intravitreal melphalan in 11 eyes, we reported 100% eye salvage and 0% recurrence with an extended 15 months mean follow-up. In this review, we analyzed published reports on IVitC in RB via PubMed, Medline, and conference proceedings citation index, electronic database search, without language restriction that included case series and reports of humans and experimental animal eyes with RB receiving IVitC.

    Nausea and vomiting are two of the most troubling side effects patients experience during chemotherapy. While newly available treatments have improved our ability to manage nausea and vomiting, anticipatory and delayed nausea and vomiting are still a major problem for patients receiving chemotherapy. Many cancer patients will delay or refuse future chemotherapy treatments and contemplate stopping chemotherapy altogether because of their fear of experiencing further nausea and vomiting. The purpose of this article is to provide an overview of the patho-psychophysiology of chemotherapy-induced nausea and vomiting and the recommended guidelines for treatment. PMID:24466408

    2015-01-01

    Despite advances in chemotherapy, radiotherapy and targeted drug development, cancer remains a disease of high morbidity and mortality. The treatment of human cancer patients with chemotherapy has become commonplace and accepted over the past 100 years. In recent years, and with a similar incidence of cancer to people, the use of cancer chemotherapy drugs in veterinary patients such as the dog has also become accepted clinical practice. The poor predictability of tumour responses to cancer chemotherapy drugs in rodent models means that the standard drug development pathway is costly, both in terms of money and time, leading to many drugs failing in Phase I and II clinical trials. This has led to the suggestion that naturally occurring cancers in pet dogs may offer an alternative model system to inform rational drug development in human oncology. In this review, we will explore the species variation in tumour responses to conventional chemotherapy and highlight our understanding of the differences in pharmacodynamics, pharmacokinetics and pharmacogenomics between humans and dogs. Finally, we explore the potential hurdles that need to be overcome to gain the greatest value from comparative oncology studies. PMID:26056373

    Patients treated with oral chemotherapy appear to have less contact with the treating providers. As a result, safety, adherence, medication therapy monitoring, and timely follow-up may be compromised. The trend of treating cancer with oral chemotherapy agents is on the rise. However, standard clinical guidance is still lacking for prescribing, monitoring, patient education, and follow-up of patients on oral chemotherapy across the healthcare settings. The purpose of this project is to establish an oral chemotherapy monitoring clinic, to create drug and lab specific provider order sets for prescribing and lab monitoring, and ultimately to ensure safe and effective treatment of the veterans we serve. A collaborative agreement was reached among oncology pharmacists, a pharmacy resident, two oncologists, and a physician assistant to establish a pharmacist-managed oral chemotherapy monitoring clinic at the VA Sierra Nevada Healthcare System. Drug-specific electronic order sets for prescribing and lab monitoring were created for initiating new drug therapy and prescription renewal. The order sets were created to be provider-centric, minimizing clicks needed to order necessary medications and lab monitoring. A standard progress note template was developed for documenting interventions made by the clinic. Patients new to an oral chemotherapy regimen were first counseled by an oncology pharmacist. The patients were then enrolled into the oral chemotherapy monitoring clinic for subsequent follow up and pharmacist interventions. Further, patients lacking monitoring or missing provider appointments were captured through a Clinical Dashboard developed by the US Department of Veterans Affairs (VA) Regional Office (VISN21) using SQL Server Reporting Services. Between September 2014 and April 2015, a total of 68 patients on different oral chemotherapy agents were enrolled into the clinic. Out of the 68 patients enrolled into the oral chemotherapy monitoring clinic, 31 patients (45

    Medical institutions are increasingly concerned about ensuring the safety of patients under their care. Failure mode and effect analysis (FMEA) is a qualitative approach based on a proactive process. Strongly promoted by the Joint Commission Accredited of Health Organization (JCAHO) since 2002, FMEA has since been adopted and widely practiced in healthcare organizations to assess and analyze clinical error events. FMEA has proven to be an effective method of minimizing errors in both manufacturing and healthcare industries. It predicts failure points in systems and allows an organization to address proactively the causes of problems and prioritize improvement strategies. The application of FMEA in chemotherapy at our department identified three main failure points: (1) inappropriate chemotherapy standard operating procedures (SOPs), (2) communication barriers, and (3) insufficient training of nurses. The application of FMEA in chemotherapy is expected to enhance the sensitivity and proactive abilities of healthcare practitioners during potentially risky situations as well as to improve levels of patient care safety.

    Introduction Metronomic chemotherapy is an emerging method of chemotherapy. Metronomic ‘lowdose’ chemotherapy regimen induces tumour dormancy and reduces cancer resistance against anticancer drugs. It tends to improve overall success rate of cancer chemotherapy than conventional cyclical regimen. Aim The aim of this systemic review was to provide comprehensive data of metronomic chemotherapy trials, regimens used and it’s outcome in cancer therapeutics. Materials and Methods Fifty chemotherapy trial data were searched sequentially from web. The main sources were official website of Clinical trial forum, USA and Clinical Trial Registry India (CTRI). Evidence on efficacy and safety of such metronomic chemotherapy trials was gathered from various data published in Medline, New England Journal of Medicine (NEJM), Lancet Oncology and other journals with high credentials. As a result of our search, out of 50 trials including breast -15(30%), colon-, 5(10%) ovarian -5(10%), prostate-5(10%) and others including haematologic, soft tissue and nervous system malignancies -20 (50%). Twenty seven trials showed favourable, 20 trials showed equivocal outcome and 3 trials reported unfavourable outcome. Overall comparison showed definitive statistical significance for using metronomic regimen (p-0.05). Conclusion It can be concluded that metronomic chemotherapy regimen seems convincing beneficial to induce tumour remission and survival at a higher than conventional regimen. More metanalyses are needed to frame common metronomic chemotherapeutic regimen. PMID:28050393

    Chemotherapy-associated liver injury (CALI) increases the risk of liver resection and may prejudice further surgery and chemotherapy. The reversibility of CALI is therefore important; however, no data concerning this are available. This study aimed to retrospectively analyze the reversibility of CALI in patients undergoing liver resection for colorectal metastases. All resections of colorectal liver metastases after oxaliplatin and/or irinotecan-based chemotherapy were included. First, liver resections were stratified by time between end of chemotherapy and hepatectomy and several possible cut-off values tested. CALI prevalence in various groups was compared. Second, CALI in the two specimens from each patient who had undergone repeat liver resections without interval chemotherapy were compared. Overall, 524 liver resections in 429 patients were analyzed. The median interval chemotherapy-surgery was 56days (15-1264). CALI prevalence did not differ significantly between groups with a chemotherapy-surgery interval <270days. Grade 2-3 sinusoidal dilatation (SOS, 19.4% vs. 40.0%, p=0.022) and nodular regenerative hyperplasia (NRH, 6.5% vs. 20.1%, p=0.063) occurred less frequently in patients with an interval >270days (n=31); prevalence of steatosis and steatohepatitis was similar in all groups. A chemotherapy-surgery interval >270days was an independent protector against Grade 2-3 SOS (p=0.009). Forty-seven patients had repeat liver resection without interval chemotherapy. CALI differed between surgeries only for a chemotherapy-surgery interval >270days (n=15), Grade 2-3 SOS having regressed in 4/5 patients and NRH in 7/8; whereas steatosis and steatohepatitis had persisted. CALI persists for a long time after chemotherapy. SOS and NRH regress only after nine months without chemotherapy, whereas steatosis and steatohepatitis persist. The patients affected by colorectal liver metastases often receive chemotherapy before liver resection, but chemotherapy causes liver

    There is a constant need for new antibacterial agents because of the unavoidable development of bacterial resistance that follows the introduction of antibiotics in clinical practice. As observed in many fields, innovation generally comes by series. For instance, a wide variety of broad-spectrum antibacterial agents became available between the 1970s and the 1990s, such as cephalosporins, penicillin/beta-lactamase inhibitor combinations, carbapenems, and fluoroquinolones. Over the last 2 decades, the arrival of new antibacterial drugs on the market has dramatically slowed, leaving a frequent gap between isolation of resistant pathogens and effective treatment options. In fact, many pharmaceutical companies focused on the development of narrow-spectrum antibiotics targeted at multidrug-resistant Gram-positive bacteria (e.g. methicillin-resistant Staphylococcus aureus, penicillin resistant Streptococcus pneumoniae, and vancomycin-resistant Enterococcus faecium). Therefore, multidrug-resistant Gram-negative bacteria (e.g. extended-spectrum beta-lactamase-producing Enterobacteriaceae, carbapenem-resistant Pseudomonas aeruginosa and Acinetobacter baumannii) recently emerged and rapidly spread worldwide. Even if some molecules were developed, new molecules for infections caused by these multidrug-resistant Gram-negative bacteria remain remarkably scarce compared to those for Gram-positive infections. This review summarises the major microbiological, pharmacological, and clinical properties of systemic antibiotics recently marketed in France (i.e. linezolid, daptomycin, tigecycline, ertapenem, and doripenem) as well as those of antibacterial drugs currently in development (i.e. ceftobiprole, ceftaroline, dalbavancin, telavancin, oritavancin, iclaprim, and ramoplanin) or available in other countries (i.e. garenoxacin, sitafloxacin, and temocillin).

    To describe the management of kissing macula retinoblastoma tumors treated with intraarterial chemotherapy. Superselective infusion of chemotherapy (combinations of melphalan, topotecan, and carboplatin) into the ophthalmic artery of children with retinoblastoma who had kissing macula tumors was administered on an outpatient basis. Results were assessed with indirect ophthalmoscopy, RetCam digital photography, B-scan ultrasonography, and electroretinograms. Three children with bilateral retinoblastoma (aged 6.1, 7, and 16 months) and kissing macula tumors in an eye were treated. All children are alive without the need for removal of the eye, systemic chemotherapy, or external beam irradiation. In each case, the kissing tumors retracted, leaving an anatomically normal fovea. Final 30-Hz flicker electroretinograms were 93.9, 65, and 63.9 μV (under anesthesia). There were no significant systemic toxicities. Superselective infusion of chemotherapy by means of the ophthalmic artery of young children with kissing macula tumors resulted in prompt shrinkage of tumors away from the fovea. There were no systemic side effects.

    Pre-operative chemotherapy with S-1 plus cisplatin is considered to be acceptable as one of the standard treatment options for gastric cancer patients with extensive lymph node metastases in Japan. Addition of trastuzumab to chemotherapy is shown to be effective for HER2-positive advanced gastric cancer patients, and we have commenced a randomized Phase II trial in March 2015 to evaluate S-1 plus cisplatin plus trastuzumab compared with S-1 plus cisplatin alone in the neoadjuvant setting for HER2-positive gastric cancer patients with ELM, which are followed by adjuvant chemotherapy with S-1 for 1 year. A total of 130 patients will be accrued from 41 Japanese institutions over 3 years. The primary endpoint is overall survival. The secondary endpoints are progression-free survival, response rate of pre-operative chemotherapy, proportion of patients with R0 resection, proportion of patients who complete the pre-operative chemotherapy and surgery, proportion of patients who complete the protocol treatment including post-operative chemotherapy, pathological response rate and adverse events.

    Background Suitable chemotherapy is needed to prolong the survival of patients with unresectable advanced or recurrent colorectal cancer. We scored the periodical changes of several prognostic markers during chemotherapy in patients with this type of cancer to discern the effectiveness of chemotherapy. Methods Twenty consecutive patients with unresectable advanced or recurrent colorectal cancer were enrolled. All patients underwent combination chemotherapy with oxaliplatin or irinotecan plus 5-fluorouracil/leucovorin. Neutrophil/lymphocyte ratio (NLR), serum C-reactive protein (CRP), serum carcinoembryonic antigen (CEA) and serum albumin (ALB) were compared between the two periods (before chemotherapy and 3 months after it was started) in each patient. The scoring system was as follows: points are added when a patient shows a decrease of NLR, CRP and CEA and an increase of ALB at 3 months after the start of chemotherapy with a possible final score of +4. On the other hand, points are reduced if a patient shows an elevation of NLR, CRP and CEA and a decrease of ALB at 3 months after the start of chemotherapy with a possible final score of −4. Results At 3 months after the start of first line chemotherapy, 13 patients showed positive scores but 7 patients showed zero or minus scores. According to our scoring system, we found the mean survival time (MST) of the 13 patients with plus scores was 34 months and this was significantly better than that of the 7 patients who showed zero or minus scores (P = 0.0008). Conclusion Our new scoring system is useful but when we find that first line chemotherapy is ineffective, we need to change it to second line chemotherapy as soon as possible. That may be the best treatment for patients with unresectable advanced or recurrent colorectal cancer. PMID:24179314

    Purpose. We retrospectively evaluated the safety and efficacy of preoperative initial hepatic arterial infusion chemotherapy (HAIC) through a port-catheter system in patients with liver dysfunction due to synchronous and unresectable liver metastases. The aim of HAIC was to improve patients' clinical condition for later surgical removal of primary colorectal cancer. Methods. Port-catheter systems were placed radiologically in 21 patients (mean age 58.6 {+-} 8.1 years) with liver dysfunction due to synchronous liver metastases from colorectal cancer. Initial HAIC of 1,000 mg/m{sup 2} 5-fluorouracil was administered weekly as a 5 hr continuous infusion through this system. Surgical removal of the primary lesion was planned after HAIC improved the liver function. Results. Port-catheter system placement was successful in all patients without severe complications. Patients were followed up for a median of 309 days (range 51-998 days). After starting HAIC, no severe adverse events that caused drug loss and treatment postponement or suspension were observed in any of the patients. HAIC was performed a mean of 4.5 {+-} 3.0 times and the liver function improved in all patients. Curative (n = 18) or palliative (n = 1) surgical removal of the primary lesion was performed. The remaining 2 patients died because extrahepatic metastases developed and their performance status worsened; thus, surgery could not be performed. The median survival times of all patients and the operated patients were 309 and 386 days, respectively. Conclusion. Initial HAIC administration is a safe and efficacious method for improving liver function prior to operative resection of primary colorectal cancer in patients with liver dysfunction due to synchronous and unresectable liver metastases.

    Nipple-sparing mastectomy is the latest advancement in the treatment of breast cancer. The authors aimed to investigate the effects of neoadjuvant and adjuvant chemotherapy in nipple-sparing mastectomy. Patients undergoing nipple-sparing mastectomy from 2006 to June of 2015 were identified. Results were stratified by presence of neoadjuvant or adjuvant chemotherapy. A total of 840 nipple-sparing mastectomies were performed. Twenty-eight were in those who received neoadjuvant chemotherapy and 93 were in patients receiving adjuvant chemotherapy. Patients receiving both neoadjuvant and adjuvant chemotherapy were included in the neoadjuvant group. Nipple-sparing mastectomies that received neoadjuvant (with or without adjuvant) chemotherapy were compared to those in patients who received adjuvant chemotherapy. Those with neoadjuvant (with or without adjuvant) chemotherapy were more likely to have explantation (p = 0.0239) and complete nipple-areola complex necrosis (p = 0.0021). Those with neoadjuvant (with or without adjuvant) chemotherapy were more likely to have implant explantation (p = 0.0015) and complete nipple-areola complex necrosis (p = 0.0004) compared to those with no chemotherapy. Compared to nipple-sparing mastectomies in patients with no chemotherapy, those with adjuvant chemotherapy were more likely to have a hematoma (p = 0.0021). Those that received both neoadjuvant and adjuvant chemotherapy were more likely to have complete nipple-areola complex necrosis compared with both the neoadjuvant chemotherapy-only and adjuvant chemotherapy-only groups (p < 0.0001). Nipple-sparing mastectomy is safe to perform in the setting of neoadjuvant and adjuvant chemotherapy. As a whole, neoadjuvant (with or without adjuvant) chemotherapy increases risk of complications.

    Interstitial pneumonia has high risk for chemotherapy-related exacerbation. Chemotherapy-related exacerbation is often fatal with respiratory failure. When we treat the cancer patient with interstitial pneumonia, it is necessary for us to regard of the efficacy of chemotherapy, and the frequency and mortality of chemotherapy-related exacerbation. All anti-cancer drugs has the possibilities of chemotherapy-related exacerbation. The incidence of chemotherapy-related exacerbation was higher in patients with target therapy agent or immune-checkpoint therapy agent, though there is not an interstitial pneumonia patient. In patients complicated with interstitial pneumonia, you should not use of these drugs, such as target therapy agent or immune-checkpoint therapy agent.

    Arteriobiliary fistula is a rare complication of hepatic intra-arterial chemotherapy. We report successful coil embolization of an arteriobiliary fistula. An 80-year-old woman underwent percutaneous placement of an indwelling catheter into the replaced right hepatic artery for intra-arterial chemotherapy of liver metastases. Coil embolization of the left hepatic artery was not performed. The patient complained of abdominal pain during intra-arterial chemotherapy. Angiography revealed a fistula between the replaced right hepatic artery and the common bile duct. The fistula was successfully treated by coil embolization via the indwelling catheter, and the indwelling catheter was removed. Although such complications usually herald the termination of intra-arterial chemotherapy, the patient underwent percutaneous implantation of a new catheter-port system, and intra-arterial chemotherapy was restarted.

  2. Neurokinin-1 receptor antagonists for chemotherapy-induced nausea and vomiting.

    2012-07-01

    Chemotherapy can be a life-prolonging treatment for many cancer patients, but it is often associated with profound nausea and vomiting that is so distressing that patients may delay or decline treatment to avoid these side effects. The discovery of several NK1 receptor antagonists is a big revolution to dealt this problem. NK1 receptor antagonists prevent both acute and delayed chemotherapy-induced nausea and vomiting (CINV). These agents act centrally at NK-1 receptors in vomiting centers within the central nervous system to block their activation by substance P released as an unwanted consequence of chemotherapy. By controlling nausea and vomiting, these agents help improve patients' daily living and their ability to complete multiple cycles of chemotherapy. They are effective for both moderately and highly emetogenic chemotherapy regimens. Their use might be associated with increased infection rates; however, additional appraisal of specific data from RCTs is needed.

    Background Nail changes associated with chemotherapy in general, and particularly with taxane and epidermal growth factor receptor inhibitor-based regimens, are common presentations in our clinical population. Currently, there are no consensuses about therapies supported by clinical trials nor are there any US Food and Drug Administration-approved treatments for this indication. Findings A 42-year-old woman with stage 2A breast cancer presented to our clinic with chemotherapy-induced paronychia. Symptoms were severe enough that cessation of chemotherapy was being considered. The patient’s chemotherapy regimen included doxorubicin, cyclophosphamide, and docetaxel. Conclusion The topical povidone-iodine/dimethylsulfoxide system is very effective in alleviating the signs and symptoms of severe paronychia associated with chemotherapy. This novel combination warrants further investigation in randomized, controlled trials to further elucidate its clinical utility. PMID:26445556

    Function and integrity disorders of the oral cavity fall into the most frequent complication of the chemotherapy of leucemias, malignant lymphomas and solid tumors. Complications associated with cancer chemotherapy can be direct ones, resulting from the toxic action of antineoplastic agents on the proliferative lining of the mouth, or indirect, as a result of myelosuppression and immunosuppression. The most frequent oral complications associated with cancer chemotherapy are mucositis, infection and bleeding. The principles of prevention and management of oral complications during cancer chemotherapy are considered in this paper.

    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.

    Purpose “In situ vaccination” using immuno-gene therapy has the ability to induce polyclonal anti-tumor responses directed by the patient’s immune system. Experimental Design Patients with unresectable MPM received two intrapleural doses of a replication-defective adenoviral vector containing the human interferon-alpha2b gene (Ad.IFN) concomitant with a 14-day course of celecoxib followed by chemotherapy. Primary outcomes were safety, toxicity, and objective response rate; secondary outcomes included progression-free and overall survival. Bio-correlates on blood and tumor were measured. Results Forty subjects were treated: 18 received first-line pemetrexed-based chemotherapy, 22 received second-line chemotherapy with pemetrexed (n=7) or gemcitabine (n=15). Treatment was generally well tolerated. The overall response rate was 25% and the disease control rate was 88%. Median overall survival (MOS) for all patients with epithelial histology was 21 months versus 7 months for patients with non-epithelial histology. MOS in the first-line cohort was 12.5 months, while MOS for the second-line cohort was 21.5 months, with 32% of patients alive at 2 years. No biologic parameters were found to correlate with response, including numbers of activated blood T cells or NK cells, regulatory T cells in blood, peak levels of interferon-α in blood or pleural fluid, induction of anti-tumor antibodies, nor an immune-gene signature in pretreatment biopsies. Conclusions The combination of intrapleural Ad.IFN, celecoxib, and chemotherapy proved safe in patients with MPM. Overall survival rate was significantly higher than historical controls in the second-line group. Results of this study support proceeding with a multi-center randomized clinical trial of chemo-immunogene therapy versus standard chemotherapy alone. PMID:26968202

    Pancreatic neuroendocrine tumors (pNETs) are rare well-differentiated neoplasms which can be functional or non-functional. They tend to have a worse prognosis than their counterpart carcinoid tumors. Current systemic treatment options for advanced, unresectable disease include somatostatin analogs, everolimus and sunitinib. Low response rates and toxicity profiles have, thus far, limited the widespread use of cytotoxic chemotherapy in this setting. In this update, we review three abstracts from the 2014 ASCO Gastrointestinal Cancers Symposium that present outcomes of the use of combination capecitabine and temozolomide in patients with advanced pNET. We summarize their results and discuss the role of this regimen in treatment algorithms for metastatic pNET.

  14. Chemotherapy-induced peripheral neuropathy.

    Chemotherapy-induced peripheral neuropathy (CIPN) is common in patients receiving anticancer treatment and can affect survivability and long-term quality of life of the patient following treatment. The symptoms of CIPN primarily include abnormal sensory discrimination of touch, vibration, thermal information, and pain. There is currently a paucity of pharmacological agents to prevent or treat CIPN. The lack of efficacious therapeutics is due, at least in part, to an incomplete understanding of the mechanisms by which chemotherapies alter the sensitivity of sensory neurons. Although the clinical presentation of CIPN can be similar with the various classes of chemotherapeutic agents, there are subtle differences, suggesting that each class of drugs might induce neuropathy via different mechanisms. Multiple mechanisms have been proposed to underlie the development and maintenance of neuropathy; however, most pharmacological agents generated from preclinical experiments have failed to alleviate the symptoms of CIPN in the clinic. Further research is necessary to identify the specific mechanisms by which each class of chemotherapeutics induces neuropathy.

    Colon cancer is one of the leading causes of cancer death worldwide. Adjuvant chemotherapy following primary surgical treatment is suggested to be beneficial in eradicating invisible disseminated small tumors in colon cancer; however, an effective drug remains to be developed. Recently, we reported a novel drug screening system using a nanoimprinting 3-dimensional (3D) culture that creates multicellular spheroids, which simulate in vivo conditions and, thereby, predict effective drugs in vivo. This study aimed to perform drug selection using our recently developed 3D culture system in a human colon cancer HCT116 cell line stably expressing red fluorescent protein (HCT116-RFP), to determine the most effective agent in a selection of clinically used antitumor agents for colon cancer. In addition, we confirmed the efficacy of the selected drug regorafenib, in vivo using a mouse model of disseminated small tumors. HCT116-RFP cells were cultured using a nanoimprinting 3D culture and in vitro drug selection was performed with 8 clinically used drugs [bevacizumab, capecitabine, cetuximab, 5-fluorouracil (5-FU), irinotecan, oxaliplatin, panitumumab and regorafenib]. An in vivo study was performed in mice bearing HCT116-RFP intraperitoneally disseminated small tumors using 3'-[18F]-fluoro-3'-deoxythymidine-positron emission tomography and fluorescence microscopy imaging to evaluate the therapeutic effects. Regorafenib was determined to be the most effective drug in the 3D culture, and significantly inhibited tumor growth in vivo, compared to the untreated control and 5-FU-treated group. The drug 5-FU is commonly used in colon cancer treatment and was used as a reference. Our results demonstrate that regorafenib is a potentially efficacious adjuvant chemotherapeutic agent for the treatment of disseminated small colon cancer and, therefore, warrants further preclinical and clinical studies.

    Preclinical data have shown the potential of the intraductal administration of chemotherapy for breast cancer prevention. Direct translation of this work has been stymied by the anatomical differences between rodents (one duct per teat) and women (5-9 ductal systems per breast). The objective of this phase I study was to show the safety and feasibility of intraductal administration of chemotherapy drugs into multiple ducts within one breast in women awaiting mastectomy for treatment of invasive cancer. Thirty subjects were enrolled in this dose escalation study conducted at a single center in Beijing, China. Under local anesthetic, one of two chemotherapy drugs, carboplatin or pegylated liposomal doxorubicin (PLD), was administered into five to eight ducts at three dose levels. Pharmacokinetic analysis has shown that carboplatin was rapidly absorbed into the bloodstream, whereas PLD, though more erratic, was absorbed after a delay. Pathologic analysis showed marked effects on breast duct epithelium in ducts treated with either drug compared with untreated ducts. The study investigators had no difficulty in identifying or cannulating ducts except in one case with a central cancer with subareolar involvement. This study shows the safety and feasibility of intraductal administration of chemotherapy into multiple ducts for the purpose of breast cancer prevention. This is an important step toward implementation of this strategy as a "chemical mastectomy", where the potential for carcinogenesis in the ductal epithelium is eliminated pharmacologically, locally, and without the need for surgery. ©2012 AACR.

    Chemotherapy-induced enteropathy (CIE) is one of the most serious complications of anticancer therapy, and tools for its early detection and monitoring are highly needed. We report on a novel fluorescence method for detection of CIE, based on molecular imaging of the related apoptotic process. The method comprises systemic intravenous administration of the ApoSense fluorescent biomarker (N,N'-didansyl-L-cystine DDC) in vivo and subsequent fluorescence imaging of the intestinal mucosa. In the reported proof-of-concept studies, mice were treated with either taxol+cyclophosphamide or doxil. DDC was administered in vivo at various time points after drug administration, and tracer uptake by ileum tissue was subsequently evaluated by ex vivo fluorescent microscopy. Chemotherapy caused marked and selective uptake of DDC in ileal epithelial cells, in correlation with other hallmarks of apoptosis (i.e., DNA fragmentation and Annexin-V binding). Induction of DDC uptake occurred early after chemotherapy, and its temporal profile was parallel to that of the apoptotic process, as assessed histologically. DDC may therefore serve as a useful tool for detection of CIE. Future potential integration of this method with fluorescent endoscopic techniques, or development of radio-labeled derivatives of DDC for emission tomography, may advance early diagnosis and monitoring of this severe adverse effect of chemotherapy.

    Over the past decade, progress in genomics and proteomics has paved the way for identifying promising macromolecular therapeutics including small RNAs, peptides and proteins. Still, the vast majority of leading drugs candidates for the treatment of CNS diseases is ineffective, mainly due to restricted passages across the BBB. Nanoparticles packaging of therapy is of particular interest for its potential to treat brain tumors, due to their ability to transport drugs through the BBB, while improving the performance of drugs by decreasing systemic and local toxicity. We chose GBM known for its poor prognosis, as a model for brain tumors. In our model we used a novel cluster-based nanoparticles termed Gagomers (GAGs) as our delivery system. GAGs are coated with the glycosamine glycan hyaluronan and can therefore bind to a specific CD44 variants expressed on tumor cells. We found that GAGs can successfully bind to both cultured cells and neurosphers (stem cells) of GBM patients and to GBM cell lines. In vitro, GAGs loaded with Kif-11 siRNA, dramatically reduced the expression of Kif11 mRNA in GBM cell lines, suggesting it can efficiently target GBM and reduce the expression of specific genes. Additionally, GAGs loaded with Doxorubicin (DXR) induced higher rates of GBM elimination than free DXR. As a next step, we examined GAGs' ability to bind specifically and efficiently to GBM cell lines in-vivo. U87 cell lines were stereotactically injected into the brains of SCID-NOD mice. Following tumor inoculation and growth mice underwent convection with GAGs loaded with Cy5 siRNA. only U87 cells were labeled with Cy5 suggesting that local treatment with GAGs can efficiently target GBM cells in-vivo. Our future plans are to examine the activity of GAGs co-entrapping siRNA and DXR on human GBM cell lines in-vitro and in-vivo. This strategy may ultimately become a novel therapeutic modality to treat GBM.

    Purpose Disparities in receipt of adjuvant chemotherapy may contribute to higher breast cancer fatality rates among black and Hispanic women compared with non-Hispanic whites. We investigated factors associated with receipt of chemotherapy in a diverse population-based sample. Patients and Methods Women diagnosed with breast cancer between August 2005 and May 2007 (N = 3,252) and reported to the Detroit, Michigan, or Los Angeles County Surveillance, Epidemiology, and End Results (SEER) registry were recruited to complete a survey. Multivariable analyses examined factors associated with chemotherapy receipt. Results The survey was sent to 3,133 patients; 2,290 completed a survey (73.1%), and 1,403 of these patients were included in the analytic sample. In multivariable models, disease characteristics were significantly associated with the likelihood of receiving chemotherapy. Low-acculturated Hispanics were more likely to receive chemotherapy than non-Hispanic whites (odds ratio [OR], 2.00; 95% CI, 1.31 to 3.04), as were high-acculturated Hispanics (OR, 1.43; 95% CI, 1.03 to 1.98). Black women were less likely to receive chemotherapy than non-Hispanic whites, but the difference was not significant (OR, 0.83; 95% CI, 0.64 to 1.08). Increasing age (even in women age < 50 years) and Medicaid insurance were associated with lower rates of chemotherapy receipt. Conclusion In this population-based sample, disease characteristics were strongly associated with receipt of chemotherapy, indicating that clinical benefit guides most treatment decisions. We found no compelling evidence that black women and Hispanics receive chemotherapy at lower rates. Interventions that address chemotherapy use rates according to age and insurance status may improve quality of systemic treatment. PMID:22869890

    With long-term follow-up, the DBCG 77B trial demonstrates that oral single-agent cyclophosphamide significantly reduces the risk of recurrence and mortality as compared with no systemic therapy in pre-menopausal patients with high-risk early breast cancer. DBCG 77B is the only randomised trial assessing single-agent cyclophosphamide; and a second comparison suggests that its benefits are comparable to what may be achieved by classic CMF. The lack of benefits from adding methotrexate and fluorouracil to cyclophosphamide paved the way for combining cyclophosphamide with anthracyclines and later taxanes. DBCG 89D showed an incremental benefit in DFS and OS from substituting methotrexate with epirubicin. The advantage of anthracycline-containing three-drug combinations over CMF was confirmed by others and in the individual-patient EBCTCG meta-analysis, while standard AC or EC for four cycles not was superior to classic CMF. A further reduction in breast cancer mortality appeared in the EBCTCG meta-analysis from the addition of a taxane to a standard AC, while the substitution of cycles or drugs with a taxane was not associated with a reduction in mortality. No apparent benefit was observed in an early analysis of the DBCG 82C evaluating the addition of CMF to tamoxifen in post-menopausal high-risk breast cancer patients. Apart from menopausal status, the two trials had identical selection criteria, and the differences in outcome warranted a long-term follow-up of the 82C trial. After ten years of follow-up, CMF in the DBCG 82C was associated with a significant improvement in DFS; but even with 24 years of follow-up, mortality was not significantly improved. The diversity in outcome from the 77C and the 82B trials triggered further studies. The 77B trial used classic CMF with oral cyclophospamide, while a four-weekly intravenous CMF regimen was used in the 82B and C trials, and a three-weekly CMF regimen was used in the succeeding 89B and D trials. The outcome following

    First- and second-line chemotherapies have been demonstrated to be effective in treatment of patients with inoperable, advanced non-small cell lung cancer (NSCLC), although the role of third-line chemotherapy remains unclear. The present investigation assessed treatment outcomes in patients with advanced NSCLC who received third-line and higher chemotherapy. This retrospective study included consecutive patients with advanced NSCLC who received at least three lines of systemic chemotherapy. A total of 72 patients who had received third-line or higher chemotherapy were included in the analysis. The median age of patients was 49 years (range 41-76), and there were 13 (18.1%) women and 59 (81.9%) men. Estimated median survival was 26 months. Moreover, overall survival was significantly longer in patients for whom disease control was achieved after second-line chemotherapy compared to those with disease progression (34 vs. 17 months, respectively). Survival after third-line treatment was significantly longer in the group with Eastern Cooperative Oncology Group (ECOG) performance status 0-1 at the beginning of third-line therapy compared to patients with a status of 2-3. In patients with advanced stage NSCLC, administration of third-line and higher systemic chemotherapy may be associated with increase in overall survival. Furthermore, greater increases in overall survival were also observed in patients for whom disease control was achieved after second-line therapy and in those with ECOG performance status of 0-1 before third-line treatment.

    Treating patients with cancer with infused or injected oncolytics is a core component of outpatient oncology practice. Currently, practices purchase drugs and then bill insurers, colloquially called "buy and bill." Reimbursement for these drugs is the largest source of gross revenue for oncology practices, and as the prices of cancer drugs have grown over time, these purchases have had significant impact on the financial health of practices and pose a risk that jeopardizes the ability of many practices to operate and provide patient care. Medicare Part B spending on drugs is under political scrutiny because of federal spending pressures, and the margin between buy and bill, lowered to 6% by the Medicare Modernization Act and further decreased to 4.3% by sequestration, is a convenient and popular target of budgetary discussions and proposals, scored to save billions of dollars over 10-year budget windows for each percentage-point reduction. Alternatives to the buy-and-bill system have been proposed to include invoice pricing, least costly alternative reimbursement, bundling of drugs into episode-of-care payments, shifting Part B drugs to the Medicare Part D benefit, and revision of the failed Competitive Acquisition Program. This article brings the perspectives of policy makers, health care economists, and providers together to discuss this major challenge in oncology payment reform.

    In spite of the early speculation by Loewenstein that one of the critical distinguishing phenotypes of cancers from normal cells was the dysfunction of gap junctional intercellular communication (GJIC), this hypothesis has not captured the attention of most birth defects and cancer researchers. Moreover, even with later demonstrations that factors that influence normal development and carcinogenesis by modulating GJIC, such as chemical teratogens and tumor-promoting chemicals, inflammatory factors, hormones and growth factors, antisense connexin genes, knockout mouse models, human inherited mutated connexin genes, si-connexin RNA, chemopreventive and chemotherapeutic chemicals, it is rare that one sees any reference to these studies by the mainstream investigators in these fields. Based on the assumption that the evolutionarily conserved connexin genes found in metazoans are needed for normal development and the maintenance of health and T. Dobzhansky's statement "Nothing in biology makes sense except in the light of evolution," a short review of the roles of endogenous and exogenous modulators of GJIC will be made in the context of the multistage, multimechanism process of carcinogenesis, the stem cell theory of carcinogenesis, the discovery and characterization of normal adult stem "cancer stem" cells and the observation that two distinct classes of GJIC-deficient cancer cells are known. The implications of these observations to a "systems biological" view of the role of gap junctions and the nutritional prevention and treatment of several chronic diseases and cancer will be discussed.

    Chemotherapy-induced mucositis is a clinically important and sometimes dose-limiting toxicity of cancer treatment, including standard-dose chemotherapy, high-dose chemotherapy and chemoradiotherapy. Consequently, dose reductions or treatment delays resulting from mucositis may impair treatment effectiveness. Symptoms are oral mucositis, dysphagia, abdominal pain and diarrhea, depending on the affected site. Although the underlying pathobiology of oral mucositis has been considerably elucidated over the past decade, there are few interventions for the prevention or treatment validated by randomized trials. The most commonly accepted intervention is basic oral care. Diarrhea is most common in patients treated with irinotecan and in some cases, life-threatening. No definitive interventions for the prevention of diarrhea exist, but there is evidence that loperamide and octreotide are effective for chemotherapy-induced diarrhea. In future, there is a need for well designed trials, preferably including a placebo or no treatment control, validating more effective interventions for managing chemotherapy- induced mucositis.

    Delayed gastric emptying symptoms are often reported after chemotherapy. This study aims to characterise the effects of chemotherapy on gastric neuro-muscular function. Patients undergoing elective surgery for oesophago-gastric cancer were recruited. Acetylcholinesterase, nNOS, ghrelin receptor and motilin expressions were studied in gastric sections from patients receiving no chemotherapy (n = 3) or oesophageal (n = 2) or gastric (n = 2) chemotherapy. A scoring system quantified staining intensity (0-3; no staining to strong). Stomach sections were separately suspended in tissue baths for electrical field stimulation (EFS) and exposure to erythromycin or carbachol; three patients had no chemotherapy; four completed cisplatin-based chemotherapy within 6 weeks prior to surgery. AChE expression was markedly decreased after chemotherapy (scores 2.3 ± 0.7, 0.5 ± 0.2 and 0 ± 0 in non-chemotherapy, oesophageal- and gastric-chemotherapy groups (p < 0.03 each) respectively. Ghrelin receptor and motilin expression tended to increase (ghrelin: 0.7 ± 0.4 vs 2.0 ± 0.4 and 1.2 ± 0.2 respectively; p = 0.04 and p = 0.2; motilin: 0.7 ± 0.5 vs 2.2 ± 0.5 and 2.0 ± 0.7; p = 0.06 and p = 0.16). Maximal contraction to carbachol was 3.7 ± 0.7 g and 1.9 ± 0.8 g (longitudinal muscle) and 3.4 ± 0.4 g and 1.6 ± 0.6 (circular) in non-chemotherapy and chemotherapy tissues respectively (p < 0.05 each). There were loss of AChE and reduction in contractility to carbachol. The tendency for ghrelin receptors to increase suggests an attempt to upregulate compensating systems. Our study offers a mechanism by which chemotherapy markedly alters neuro-muscular gastric function.

    Continuation maintenance treatment with pemetrexed is approved by current clinical guidelines as a category 2A recommendation after induction therapy with cisplatin and pemetrexed chemotherapy (CP strategy) for patients with advanced nonsquamous non-small-cell lung cancer (NSCLC). However, the cost-effectiveness of the treatment remains unclear. We completed a trial-based assessment, from the perspective of the Chinese health care system, of the cost-effectiveness of maintenance pemetrexed treatment after a CP strategy for patients with advanced nonsquamous NSCLC. A Markov model was developed to estimate costs and benefits. It was based on a clinical trial that compared continuation maintenance pemetrexed therapy plus best supportive care (BSC) versus placebo plus BSC after a CP strategy for advanced nonsquamous NSCLC. Sensitivity analyses were conducted to assess the stability of the model. The model base case analysis suggested that continuation maintenance pemetrexed therapy after a CP strategy would increase benefits in a 1-, 2-, 5-, or 10-year time horizon, with incremental costs of $183,589.06, $126,353.16, $124,766.68, and $124,793.12 per quality-adjusted life-year gained, respectively. The most sensitive influential variable in the cost-effectiveness analysis was the utility of the progression-free survival state, followed by proportion of patients with postdiscontinuation therapy in both arms, proportion of BSC costs for PFS versus progressed survival state, and cost of pemetrexed. Probabilistic sensitivity analysis indicated that the cost-effective probability of adding continuation maintenance pemetrexed therapy to BSC was zero. One-way and probabilistic sensitivity analyses revealed that the Markov model was robust. Continuation maintenance of pemetrexed after a CP strategy for patients with advanced nonsquamous NSCLC is not cost-effective based on a recent clinical trial. Decreasing the price or adjusting the dosage of pemetrexed may be a better option

    The time-limited efficacy of reversible EGFR-TKIs in patients with advanced non-small cell lung cancer (NSCLC) with EGFR gene activating mutations is associated with development of treatment resistance after some period of therapy. This resistance predominantly results from secondary mutations located in EGFR gene, especially T790M substitution. There is limited information available concerning the prevalence of primary T790M mutations in patients with metastatic NSCLC tumors before treatment with EGFR-TKIs. The aim of work was to assess the prevalence of de novo T790M mutations in EGFR gene in tissue samples from NSCLC metastatases in central nervous system (CNS) in both chemotherapy and EGFR-TKI naive NSCLC patients. We analyzed DNA samples isolated from paraffin-embedded tissue from CNS metastases for T790M mutations using real-time PCR and TaqMan probe against the T790M mutant sequence. The tissue samples were taken during palliative neurosurgery in 143 NSCLC patients. Amplification of the T790M-specific sequence was detected in 25 patients (17.5 %). The quantity of mutated DNA was less than 1 % in all samples with amplification, and in vast majority (20 patients, 14 % of all samples) it was even less that 0.1 %. In 5 patients (3.5 %) quantity of mutated DNA ranged from 0.1 to 1 % and true positive results of T790M mutation presence in these patients were most possible. Amplification of this sequence was not concurrent with common EGFR mutations and was not associated with sex, smoking status and pathological type of cancer. There is a possibility to detect the primary T790M mutation in brain metastases of NSCLC in EGFR-TKIs naïve patients.

    Advances in supportive care have increased the likelihood that previously less common adverse effects of chemotherapy will be more evident. The incidence of chemotherapy-induced peripheral neuropathy (CIPN) is increasing because more neurotoxic drugs have been developed and because patients are living longer and receiving multiple chemotherapy regimens. This article reviews the anatomy of the peripheral nervous system, the proposed mechanisms of CIPN, and manifestations of CIPN from vinca alkaloids, taxanes, and platinum analogs. Major topics of this article are evidence-based data regarding symptom management, a review of medical management, and a synthesis of nursing care for patients at risk for or experiencing CIPN.

    The potentiation of chemotherapeutic agents by radiation sensitizers has been extensively studied for several years. There is little doubt that the effectiveness of certain anti-cancer drugs, primarily alkylating agents, can readily be enhanced both in vitro and in vivo through the addition of a sensitizer. While enhanced effects have been observed in certain critical normal tissues, in general most animal model studies have demonstrated a therapeutic gain at large sensitizer doses. This approach to combination therapies therefore appears promising. Yet many questions concerning the interaction between chemotherapeutic agents and radiosensitizers, particularly in the aspects of modification of chemotherapy by nitroimidazoles are reviewed and discussed. These address the importance in chemopotentiation of (i) hypoxia, (ii) alterations in DNA damage and/or repair, (iii) depletion of intracellular sulfhydryls and (iv) modification of drug pharmacokinetics.

    The combination of hormonal treatment based on a long-acting delivery system for the agonist [6-D-tryptophan]luteinizing hormone-releasing hormone ([D-Trp6]-LH-RH) with the chemotherapeutic agent Novantrone (mitoxantrone dihydrochloride) was studied in the Dunning R3327H rat prostate cancer model. Microcapsules of [D-Trp6]-LH-RH formulated from poly(DL-lactide-co-glycolide) and calculated to release a controlled dose of 25 micrograms/day were injected intramuscularly once a month. Novantrone (0.25 mg/kg) was injected intravenously once every 3 weeks. Three separate experiments were carried out. When the therapy was started 45 days after transplantation and continued for 70 days, tumor volume in the presence of the microcapsules (966 +/- 219 mm3) or Novantrone (3606 +/- 785 mm3) given alone was significantly decreased compared to controls (14,476 +/- 3045 mm3). However, the combination of microcapsules and Novantrone caused a greater inhibition of tumor growth (189 +/- 31 mm3) than the single agents. Similar effects were seen when the percent increase in tumor volume was examined. Tumor volume increased 10,527 +/- 1803% for the control group. The inhibition of growth caused by the [D-Trp6]LH-RH microcapsules alone (672 +/- 153% increase in volume) was again greater than that caused by Novantrone alone (2722 +/- 421% increase). The combination of the two agents was again the most effective, resulting in an increase in tumor volume of only 105 +/- 29%. Control tumors weighed 30.0 +/- 6.5 g. Tumor weights were much less in the groups treated with either microcapsules (3.28 +/- 0.69 g) or Novantrone (19.53 +/- 3.3 g) alone. The lowest tumor weights after 70 days of treatment were obtained in the group that received the combination of [D-Trp6]LH-RH microcapsules and Novantrone (1.02 +/- 0.2 g). Testes and ventral prostate weights were significantly diminished by the administration of microcapsules of [D-Trp6]LH-RH alone or in combination with Novantrone. In both of these

    Worldwide research on the human genome exerts a major impact on medical science. The growing evidence that genetic polymorphisms in the metabolism, the disposition, and the targets of drugs can have an even greater influence on the efficacy and the toxicity led to the creation of a novel chemotherapeutic strategy, personalized medicine. Much effort has been directed toward identifying the indicators of individual response to drugs, and these studies have provided a variety of potent predictive markers of individual drug response, which include some significant markers in clinical practice with sufficient evidence. Personalized medicine based on the response prediction using genomic marker is increasingly being recognized as a practical treatment approach in cancer chemotherapy, and to be indispensable when molecular targeted drugs are involved in the therapy. Even so, the ingenious and intricate mechanism of individual drug response creates obstacles in predicting chemotherapeutic response: Multiple factors are involved in the mechanisms, and key factors for drug response vary significantly among individuals. DNA chip technology enables us to overview a huge number of gene expressions simultaneously, but gene expression profiles of drug sensitivity vary considerably even for the same drug, which shows the limited value of a static microarray-expression profile as a marker aimed at individualizing patient therapy. Selection of a set of truly significant genomic markers and understanding of their interplay are of key importance in prediction of individual response to drug therapies. Challenges to such biological complexity are now started to identify a better genomic marker. The contribution of genomic marker research to anticancer chemotherapy and problems of the day were reviewed.

    Trace elements might be associated with the development of hepatocellular carcinoma (HCC) and the efficacy of chemotherapy against HCC. Therefore, this study aimed to explore the association between trace elements and efficacy of chemotherapy in patients with HCC. Cancer, cancer-adjacent, and cancer-free tissues were collected intraoperatively from 55 patients with HCC between January 2001 and April 2004 at the Affiliated Tumor Hospital of Guangxi Medical University in Guangxi (China), a high HCC incidence area in the world. Trace element levels were analyzed by atomic absorption spectrophotometry. In vitro sensitivity of cancer cells to five chemotherapeutic drugs (5-fluorouracil, doxorubicin, cisplatin, carboplatin, and mitomycin) was tested using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay in cancer cells from 32 patients. Zinc, copper, manganese, and selenium levels had the same gradient distribution in different liver tissues: cancer < cancer-adjacent < cancer-free tissues. Copper levels of cancer tissues were negatively correlated with body weight (r = -0.278, P = 0.027), while manganese and selenium levels were negatively correlated with age (r = -0.297, P = 0.015; r = -0.285, P = 0.018, respectively). Simple correlation analyses revealed that the carboplatin sensitivity was negatively correlated with selenium levels of cancer tissues, while doxorubicin sensitivity was negatively correlated with manganese levels (r = -0.497, P = 0.004). Partial correlation analyses showed that doxorubicin sensitivity only was negatively correlated with manganese levels (r = -0.450, P = 0.014). These results suggest that the selenium and manganese content in primary HCC tissues could influence the response of the HCC cells to carboplatin and doxorubicin. These preliminary results provide a basis for future studies.

    It is assumed that the spread of breast cancer cells via the lymphatic system might be influenced by inflammatory reactions and/or the application of chemotherapy or molecularly targeted therapy. Therefore, we analysed survival according to lymphatic vessel density (LVD), lymphovascular invasion (LVI) (both assessed using podoplanin as immunohistochemical marker of lymphatic endothelium) and well-established clinico-pathological features in a group of 358 patients with invasive ductal breast cancer: 139 chemotherapy-naïve (pT1-2/pN0/M0) and 219 treated with chemotherapy (pT1-4/pN1-3/M0). Univariate analysis revealed that high LVD was related to unfavourable disease-free survival (DFS) in pN0/chemotherapy/trastuzumab-naïve patients (P = 0.028). Conversely, in pN+/chemotherapy-treated individuals high LVD was related to favourable DFS (P = 0.019). LVI was a significant indicator of survival (P = 0.005) only in pN0/chemotherapy/trastuzumab-naïve patients. The following parameters were significant independent adverse prognostic factors for DFS: (i) in pN0/chemotherapy/trastuzumab-naïve patients: high LVD (LVD > 7 vessels/mm2; RR = 2.7, P = 0.039), LVI (RR = 3.3, P = 0.046) and high tumor grade (G3 vs. G1 + G2; RR = 2.6, P = 0.030); (ii) in pN+/chemotherapy/trastuzumab-treated patients: low LVD (RR = 1.8, P = 0.042), the number of involved lymph nodes (pN3 vs. pN1-2; RR = 2.3, P = 0.012) and the breast cancer subtype (expression of steroid receptors together with HER2 immunonegativity and high proliferation index vs. other breast cancer immunophenotypes; RR = 3.0, P < 0.001). High LVD may identify high progression risk in pN0/chemotherapy/trastuzumab-naïve patients, and low progression risk in pN+/chemotherapy-treated patients. This phenomenon might be explained by potential involvement of lymphangiogenesis in two processes related to cancer eradication: a chemotherapy-stimulated activity of the immune system against cancer cells, or increased tumour drainage

    This study was performed to evaluate the outcomes of patients with locally advanced breast cancer (LABC) who were treated with a multidisciplinary approach including primary systemic chemotherapy and noncross-resistant adjuvant chemotherapy. Patients with LABC received 4 or 6 cycles of doxorubicin and docetaxel (DT) as primary systemic chemotherapy (PST) every 21 days. Patients with adequate response underwent surgery followed by adjuvant chemotherapy according to pathologic response: complete (pCR), 2 more cycles of DT; partial (pPR), 2 more cycles of DT followed by 6 cycles of cyclophosphamide, methotrexate, and 5-fluorouracil (5-FU) (CMF); and minor (pMR), 6 cycles of CMF. Patients then received radiation and tamoxifen (hormone receptor-positive patients only). Eighty-eight patients were evaluable. Seventy-four patients had an adequate response to DT and were considered operable, and 72 underwent surgery. Ten patients (13.9%) achieved a pCR, 22 (30.5%) achieved a pPR, and 40 achieved a pMR (55.5%). Fourteen patients were considered nonoperable after DT and underwent salvage CMF therapy. Five of these patients underwent surgery and 1 had achieved a pCR. The estimated 5-year recurrence-free survival (RFS) rates for patients with pCR, pPR, and pMR were 80%, 77%, and 59%, respectively, and the estimated 5-year overall survival (OS) rates were 90%, 91%, and 74%, respectively. The 5-year OS rates were 82% for initially operable and 21% for initially inoperable patients (P < or = .001) Multidisciplinary therapy that includes PST with DT and adjuvant therapy with CMF administered according to the clinical and pathologic response is associated with high long-term RFS and OS rates in patients with LABC. Clinical or pathologic PR or CR to DT predicts improved RFS and OS.

    Outpatient chemotherapy is a core treatment for haematological malignancies; however, its toxicities frequently lead to distressing/potentially life-threatening side-effects (neutropenia/infection, nausea/vomiting, mucositis, constipation/diarrhoea, fatigue). Early detection/management of side-effects is vital to improve patient outcomes, decrease morbidity and limit lengthy/costly hospital admissions. The ability to capture patient-reported health data in real-time, is regarded as the 'gold-standard' to allow rapid clinical decision-making/intervention. This paper presents the protocol for a Phase 3 multi-site randomised controlled trial evaluating a novel nurse-led Telehealth intervention for remote monitoring/management of chemotherapy side-effects in Australian haematological cancer patients. Two hundred and twenty-two patients will be recruited from two hospitals. Eligibility criteria include: diagnosis of chronic lymphocytic leukaemia/Hodgkin's/non-Hodgkin's lymphoma; aged ≥ 18 years; receiving ≥ 2 cycles chemotherapy. Patients will be randomised 1:1 to either the control or intervention arm with stratification by diagnosis, chemotherapy toxicity (high versus low), receipt of previous chemotherapy and hospital. Patients allocated to the control arm will receive 'Usual Care' whilst those allocated to the intervention will receive the intervention in addition to 'Usual Care'. Intervention patients will be provided with a computer tablet and software prompting twice-daily completion of physical/emotional scales for up to four chemotherapy cycles. Should patient data exceed pre-determined limits an Email alert is delivered to the treatment team, prompting nurses to view patient data, and contact the patient to provide clinical intervention. In addition, six scheduled nursing interventions will be completed to educate/support patients in use of the software. Patient outcomes will be measured cyclically (midpoint and end of cycles) via pen

    Purpose With the use of case presentations, we present a review of the role of systemic chemotherapy in oligometastatic colorectal cancer and suggest ways to integrate clinical research findings into the interdisciplinary management of this potentially curable subset of patients. Methods This educational review discusses the role of chemotherapy in the management of oligometastatic metastatic colorectal cancer. Results In initially resectable oligometastatic colorectal cancer, the goal of chemotherapy is to eradicate micrometastatic disease. Perioperative 5-fluorouracil and oxaliplatin along with surgical resection can result in 5-year survival rates as high as 57%. With the development of increasingly successful chemotherapy regimens, attention is being paid to the use of chemotherapy to convert patients with initially unresectable metastasis into patients with a chance of surgical cure. The choice of chemotherapy regimen requires consideration of the goals of therapy and assessment of both tumor and patient-specific factors. Discussion Herein we discuss the choice and timing of chemotherapy in patients with initially resectable and borderline resectable metastatic colorectal cancer. Coordinated multidisciplinary care of such patients can optimize survival outcomes and result in the cure of patients with this otherwise lethal disease. PMID:26100816

    The prevalence of patients on dialysis has increased and these patients present a challenge for chemotherapy administration when diagnosed with cancer. A consensus on the dosage and timing of different chemotherapeutic agents in relation to dialysis has not been established. We describe the pattern of care and treatment outcome for cancer patients on dialysis in our institution. The dataset from the Australia and New Zealand Dialysis and Transplant Registry of patients on dialysis who had a diagnosis of cancer was obtained and matched to the pharmacy records in our institution to identify patients who had received chemotherapy while on dialysis. Relevant clinical information including details of the dialysis regimen, chemotherapy administration and adverse events was extracted for analysis. Between July 1999 and July 2014, 21 patients on dialysis were included for analysis. Five (23.8%) received chemotherapy, most of which was administered before dialysis sessions. As a result of adverse events, one patient discontinued treatment; two other patients required dose reduction or treatment delay. Chemotherapy administration was feasible in cancer patients on dialysis, but chemotherapy usage was low. Better understanding of the altered pharmacokinetics in patients on dialysis may improve chemotherapy access and practice.

    The use of selective internal radiation therapy with yttrium 90 resin microspheres (SIR-Spheres(®)) in chemotherapy-resistant colorectal cancer liver metastases has been associated with favorable progression-free survival (PFS) and overall survival when given alone or concurrently with chemotherapy. We conducted a single institute retrospective trial to explore the potential impact of SIR-Spheres(®) with concurrent chemotherapy vs. SIR-Spheres(®) alone on liver PFS in patients with colorectal liver metastases (CRLM). Patients with 5-fluorouracil-refractory CRLM treated with SIR-Spheres(®) between 2009 and 2014 were identified. Patients were excluded if they received any chemotherapy/targeted regimen following radioembolization on which they did not previously progress. This strategy was adopted to minimize the impact of post-SIR-Spheres(®) systemic therapy bias on PFS. Twenty-seven patients satisfied inclusion criteria and were included in this analysis. Patients' demographics were similar between the two treatment arms, except for the median number of prior therapies. No associated ≥ grade 3 toxicities were noted. Liver disease control rates were 84% and 14% on the SIR-Spheres(®) plus chemotherapy arms and SIR-Spheres(®) alone arms, respectively (P=0.001). Median PFS in the liver was 176 days in the SIR-Spheres(®) plus chemotherapy group vs. 91 days in the SIR-Sphere(®) alone group (P=0.0009). Median overall survival was 212 days in the SIR-Spheres(®) plus chemotherapy group vs. 154 days in the SIR-Spheres(®) alone group (P=0.1023). In patients with 5-fluorouracil-refractory disease, SIR-Spheres(®) plus chemotherapy is associated with an increased liver disease control rate and a prolonged liver PFS in comparison with SIR-Spheres(®) alone.

    Purpose/Objectives To explore virtual reality (VR) as a distraction intervention to relieve symptom distress in adults receiving chemotherapy treatments for breast, colon, and lung cancer. Design Crossover design in which participants served as their own control. Setting Outpatient clinic at a comprehensive cancer center in the southeastern United States. Sample 123 adults receiving initial chemotherapy treatments. Methods Participants were randomly assigned to receive the VR distraction intervention during one chemotherapy treatment and then received no intervention (control) during an alternate matched chemotherapy treatment. The Adapted Symptom Distress Scale–2, Revised Piper Fatigue Scale, and State Anxiety Inventory were used to measure symptom distress. The Presence Questionnaire and an open-ended questionnaire were used to evaluate the subjects’ VR experience. The influence of type of cancer, age, and gender on symptom outcomes was explored. Mixed models were used to test for differences in levels of symptom distress. Main Research Variables Virtual reality and symptom distress. Findings Patients had an altered perception of time (p < 0.001) when using VR, which validates the distracting capacity of the intervention. Evaluation of the intervention indicated that patients believed the head-mounted device was easy to use, they experienced no cybersickness, and 82% would use VR again. However, analysis demonstrated no significant differences in symptom distress immediately or two days following chemotherapy treatments. Conclusions Patients stated that using VR made the treatment seem shorter and that chemotherapy treatments with VR were better than treatments without the distraction intervention. However, positive experiences did not result in a decrease in symptom distress. The findings support the idea that using VR can help to make chemotherapy treatments more tolerable, but clinicians should not assume that use of VR will improve chemotherapy

    Knowledge-based decision support systems traditionally rely on condition-action rule structures, an adequate representation for simple decisions. In complex domains an important part of decision-making includes analysis of the consequences of a decision. Consequential reasoning is particularly important in medicine as potential risk and/or benefit can be included. In this paper, a knowledge structure and inference engine is described that permits the representation and analysis of consequential reasoning in a computer-assisted decision support system. The use of consequential reasoning is then illustrated in an application designed to assist in cancer chemotherapy decisions. The result is a method that is sensitive to individual patient reactions to chemotherapy agents, permitting an individualized approach to therapy. Individualized drug therapy is becoming increasingly feasible due to advances made in the field of genomics. The system is structured so that new information can be incorporated easily. Although the application shown here is to chemotherapy, the general methodology can be used in any area in which the consequences should significantly influence the decision.

    In the ambulatory care setting, chemotherapy regimens have become increasingly complex with the combination of induction treatments and oral medications. Nurses at one cancer center implemented an oral adherence tracking documentation system in the electronic health record (EHR). Oncology nurses assessed and monitored adherence to oral chemotherapy at each clinical encounter and during telephone calls and then documented findings in the EHR. After implementing this new standardized approach, adherence rates were captured as a metric for the organization.

    Thyroid hormones (TH) are regulated by the hypothalamic-pituitary axis, which plays an important role in cell growth, differentiation, development and other aspects of metabolism. It is believed that an active hypothalamic-pituitary axis increases the susceptibility of thyroid dysfunction during systemic chemotherapy. In order to investigate the relation between thyroid function and chemotherapy the present study was designed to investigate TH in breast cancer patients receiving at least three cycles of chemotherapy. The levels of TH were measured at the baseline and before each cycle of chemotherapy. Blood samples for estimation of TH levels were collected from 80 (pre-menopausal-40; post-menopausal-40) breast cancer patients just before they were undergoing--1st, 2nd, 3rd and 4th cycle of chemotherapy. The serum was separated and T3, T4 and TSH levels were determined by chemiluminescence method. T3 and T4 were found significantly decreased and TSH was found significantly increased after 1st (p<0.001), 2nd (p<0.0001) and 3rd cycle of chemotherapy (p<0.0001). The variation of T3 levels (decreased) and TSH levels (increased) was found more in post-menopausal (p<0.0001) women then in pre-menopausal women after 3rd cycle of chemotherapy as compared to baseline (p<0.001). TH were remarkably altered after each cycle of chemotherapy leading to decline in thyroid function of breast cancer patients. Further, the results also indicated that post- menopausal women were more prone towards decline in thyroid function then pre-menopausal women. The present study proposes the monitoring of TH after each cycle of chemotherapy in breast cancer patients.

    Chemotherapy-induced neuropathy is a painful and debilitating adverse effect of certain chemotherapy drugs. There have not been any patient-centered, easily accessible Web-based interventions to assist with self-management of chemotherapy-induced neuropathy. The aims of this study were to evaluate usability and acceptability and to estimate an effect size of a Web-based intervention for assessing and managing chemotherapy-induced neuropathy. Participants (N = 14) were instructed to complete the Creativity, Optimism, Planning, and Expert Information for Chemotherapy-Induced Peripheral Neuropathy program and provide verbal responses to the program. Participants completed the Chemotherapy Induced Peripheral Neuropathy Assessment Tool and Post-Study System Usability Questionnaire. Iterative changes were made to the COPE-CIPN. Participants were asked to provide feedback on the revised COPE-CIPN, repeat the Chemotherapy Induced Peripheral Neuropathy Assessment Tool, and evaluate acceptability using the Acceptability e-Scale. The COPE-CIPN demonstrated high usability (mean, 1.98 [SD, 1.12]) and acceptability (mean, 4.40 [SD, 0.52]). Comments indicated that the interface was easy to use, and the information was helpful. While neuropathy symptoms continued to increase in this group of patients receiving neurotoxic chemotherapy, there was a decrease in mean level of interference with activities from 53.71 to 39.29 over 3 to 4 months, which indicated a moderate effect (d = 0.39) size. The COPE-CIPN may be a useful intervention to support self-management of chemotherapy-induced neuropathy.

    To investigate the longitudinal relationship between chemotherapy-induced peripheral neuropathy (CIPN) symptoms (sx) and brain perfusion changes in patients with breast cancer. Interaction of CIPN-sx perfusion effects with known chemotherapy-associated gray matter density decrease was also assessed to elucidate the relationship between CIPN and previously reported cancer treatment-related brain structural changes. Patients with breast cancer treated with (n = 24) or without (n = 23) chemotherapy underwent clinical examination and brain magnetic resonance imaging at the following three time points: before treatment (baseline), 1 month after treatment completion, and 1 year after the 1-month assessment. CIPN-sx were evaluated with the self-reported Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity four-item sensory-specific scale. Perfusion and gray matter density were assessed using voxel-based pulsed arterial spin labeling and morphometric analyses and tested for association with CIPN-sx in the patients who received chemotherapy. Patients who received chemotherapy reported significantly increased CIPN-sx from baseline to 1 month, with partial recovery by 1 year (P < .001). CIPN-sx increase from baseline to 1 month was significantly greater for patients who received chemotherapy compared with those who did not (P = .001). At 1 month, neuroimaging showed that for the group that received chemotherapy, CIPN-sx were positively associated with cerebral perfusion in the right superior frontal gyrus and cingulate gyrus, regions associated with pain processing (P < .001). Longitudinal magnetic resonance imaging analysis in the group receiving chemotherapy indicated that CIPN-sx and associated perfusion changes from baseline to 1 month were also positively correlated with gray matter density change (P < .005). Peripheral neuropathy symptoms after systemic chemotherapy for breast cancer are associated with changes in cerebral perfusion and gray

    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/m2; IP PTX [without intravenous (IV) PTX], 80 mg/m2; and IP PTX (with IV PTX), 20 mg/m2. 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.

    Great advances have been made in chemotherapy in advanced and metastatic non-small-cell lung cancer (NSCLC), and a major milestone was reached with the administration of neoadjuvant chemotherapy in stage IIIA N2 disease. The systemic nature of lung cancer has been confirmed by many genetic analyses documenting micrometastases in negative lymph nodes and bone marrow, and mRNA gene overexpression as a surrogate of cancer cells has been identified in peripheral blood. Furthermore, serum or plasma cell-free tumor DNA has been observed even in tumors with a diameter of less than 2 cm. Pharmacogenetic screening can lead to tailored chemotherapy even in patients with early disease through the use of a genetic tool kit that will allow us to optimize the use of chemotherapy by using serial measurements of serum DNA that can help to detect residual disease and re-assess the chemosensitivity of sub-clinical micrometastatic disease. The ongoing (neo)adjuvant taxol/carboplatin hope (NATCH) trial is testing the value of three cycles of chemotherapy given pre- or post-operatively compared with surgery alone and will analyze genetic abnormalities in serum DNA at three different points during patient follow-up. Our major concern in this review is to analyze the pros and cons of chemotherapy in NSCLC. Although this review is not a formal meta-analysis, we have discussed the most relevant published studies in this field. We conclude that not only is there no evidence of detrimental effects of chemotherapy, in fact, there are many indications that chemotherapy induces response in up to 80% of patients and downgrades N2 disease in up to 50% of patients. This translates into significantly better survival when accompanied by complete resection. Since at least 50% of patients with stage IB disease develop distant metastases, it seems logical to explore the role of chemotherapy in early disease.

At 1 month, neuroimaging showed that for the group that received chemotherapy, CIPN-sx were positively associated with cerebral perfusion in the right superior frontal gyrus and cingulate gyrus, regions associated with pain processing (P < .001). Longitudinal magnetic resonance imaging analysis in the group receiving chemotherapy indicated that CIPN-sx and associated perfusion changes from baseline to 1 month were also positively correlated with gray matter density change (P < .005). Conclusion Peripheral neuropathy symptoms after systemic chemotherapy for breast cancer are associated with

    Tuberculosis is a leading killer of young adults worldwide and the global scourge of multi-drug resistant tuberculosis is reaching epidemic proportions. It is endemic in most developing countries and resurgent in developed and developing countries with high rates of human immunodeficiency virus infection. This article reviews the current situation in terms of drug delivery approaches for tuberculosis chemotherapy. A number of novel implant-, microparticulate-, and various other carrier-based drug delivery systems incorporating the principal anti-tuberculosis agents have been fabricated that either target the site of tuberculosis infection or reduce the dosing frequency with the aim of improving patient outcomes. These developments in drug delivery represent attractive options with significant merit, however, there is a requisite to manufacture an oral system, which directly addresses issues of unacceptable rifampicin bioavailability in fixed-dose combinations. This is fostered by the need to deliver medications to patients more efficiently and with fewer side effects, especially in developing countries. The fabrication of a polymeric once-daily oral multiparticulate fixed-dose combination of the principal anti-tuberculosis drugs, which attains segregated delivery of rifampicin and isoniazid for improved rifampicin bioavailability, could be a step in the right direction in addressing issues of treatment failure due to patient non-compliance.

    Capillary zone electrophoresis (CZE) was investigated for its suitability to monitor proteinuria occurring during nephrotoxic drug therapy. Urine samples of tumor patients receiving chemotherapy consisting of carboplatin, etoposide, and ifosfamide were concentrated and desalted in microconcentrators and analyzed in two different alkaline CZE buffer systems. Reduction of electroosmotic flow (EOF) by the addition of putrescine increased the number of resolved protein peaks. Both CZE methods were linear between 2.5 and 50 microg/ml, exhibited satisfactory precision (relative standard deviation <10%) and were suitable for monitor the time course of proteinuria after chemotherapy administration. In contrast to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), CZE detected interindividual differences in protein patterns. Whereas these differences hampered a direct quantification of proteins in urine, they may contain information on the type or extent of kidney damage.

  13. The double-edged sword: Neurotoxicity of chemotherapy.

    The number of available therapies for hematologic malignancies continues to grow at a rapid pace. Unfortunately, many of these treatments carry both central and peripheral nervous system toxicities, potentially limiting a patient's ability to tolerate a full course of treatment. Neurotoxicity with chemotherapy is common and second only to myelosuppression as a reason to limit dosing. This review addresses the neurotoxicity of newly available therapeutic agents including brentuximab vedotin and blinatumomab as well as classic ones such as methotrexate, vinca alkaloids and platinums. Although peripheral neuropathy is common with many drugs, other complications such as seizures and encephalopathy may require more immediate attention. Rapid recognition of adverse neurologic effects may lead to earlier treatment and appropriate adjustment of dosing regimens. In addition, knowledge of common toxicities may help differentiate chemotherapy-related symptoms from actual progression of cancer into the CNS.

  14. Chemotherapy, immunity and microbiota—a new triumvirate?

    The growing relevance of the gut microbiota to various human diseases may also directly impinge on the efficacy of chemotherapeutics. A recent study shows that subcutaneous tumors fail to respond to immunotherapy and platinum chemotherapy after antibiotic treatment1, whereas another study reports that the effect of cyclophosphamide on the antitumor immune response relies on the presence of a ‘healthy’ gut microbiota2. The mechanisms mediating the role of the microbiota in the immune system during chemotherapy seem to involve the innate and adaptive immune arms. The unexpected influence of commensal intestinal bacteria in the outcome of cancer treatment and the function of anticancer immunity poses new questions from a preclinical and clinical standpoint in the cancer field.

    FOLFOX 4 chemotherapy (5-fluorouracil, leucovorin and oxaliplatin) is the standard adjuvant treatment for stage III colon cancer. The principal secondary effects described are haematological, gastro-intestinal or neurological. A single case of obliterative bronchiolitis with organising pneumonia has been described recently. We report the case of a female patient aged 74 years who, after 12 courses of FOLFOX 4 chemotherapy, developed acute onset of severe shortness of breath and a dry cough but remained afebrile. A thoracic CT-scan showed symmetrical bilateral interstitial infiltration that was reticular in appearance, and predominantly basal and peripheral in distribution. Broncho-alveolar lavage revealed an alveolitis with 9% eosinophils and 4% neutrophils. Transbronchial biopsies showed the appearances of obliterative bronchiolitis with organising pneumonia. Systemic corticosteroid treatment led to a remarkable clinical and functional improvement. To our knowledge, this is the second case of obliterative bronchiolitis with organising pneumonia that has been described following adjuvant treatment based on FOLFOX 4.

    Recently investigators have used analysis of administrative/billing datasets to answer clinical and pharmacoepidemiology questions in pediatric oncology. However, the accuracy of pharmacy data from administrative/billing datasets have not yet been evaluated. The primary objective of this study was to determine the concordance of Pediatric Health Information System (PHIS) administrative/billing chemotherapy data with Children's Oncology Group (COG) protocol-mandated chemotherapy and to assess the implications of this level of concordance for further PHIS research. Data from 384 pediatric patients (1,060 courses of chemotherapy) with acute myeloid leukemia treated on COG clinical trial AAML0531 were previously merged with PHIS data. PHIS chemotherapy administrative/billing data were reviewed for the first three courses of chemotherapy. Accuracy was assessed using three metrics: recognizability of chemotherapy pattern by course, chemotherapy administration pattern by individual medication, and concordance with the number of days of protocol-defined chemotherapy. The chemotherapy pattern was recognizable in 87.3% of courses when course-wide accuracy was assessed. Chemotherapy administration pattern varied by medication. Cytarabine had perfect concordance 70.9% of the time, daunorubicin had perfect concordance 77.4% of the time, and etoposide had perfect concordance 67.8% of the time. The accuracy of chemotherapy administrative/billing data supports the continued use of PHIS data for epidemiology studies as long as investigators perform data quality control checks and evaluate each specific medication prior to undertaking definitive analyses. © 2015 Wiley Periodicals, Inc.

  17. Natural products for cancer chemotherapy

    2011-01-01

    Summary For over 40 years, natural products have served us well in combating cancer. The main sources of these successful compounds are microbes and plants from the terrestrial and marine environments. The microbes serve as a major source of natural products with anti‐tumour activity. A number of these products were first discovered as antibiotics. Another major contribution comes from plant alkaloids, taxoids and podophyllotoxins. A vast array of biological metabolites can be obtained from the marine world, which can be used for effective cancer treatment. The search for novel drugs is still a priority goal for cancer therapy, due to the rapid development of resistance to chemotherapeutic drugs. In addition, the high toxicity usually associated with some cancer chemotherapy drugs and their undesirable side‐effects increase the demand for novel anti‐tumour drugs active against untreatable tumours, with fewer side‐effects and/or with greater therapeutic efficiency. This review points out those technologies needed to produce the anti‐tumour compounds of the future. PMID:21375717

    New formulations, therapeutic switching of the established drugs amphotericin B and paromomycin, and the serendipitous discovery of miltefosine have markedly improved leishmaniasis chemotherapy in the past 21 years. The situation for the two trypanosomiases has been less encouraging. Apart from the introduction of eflornithine for the treatment of late-stage human African trypanosomiasis, with its serious limitations in terms of cost and difficulty of administration, no new drugs have been incorporated into the chemotherapeutic arsenal in the past 25 years, despite important advances in knowledge of the biology of the etiological agents and the pathophysiology of these diseases. In the case of Chagas disease, several classes of compound that target the validated biochemical pathways of the parasite (e.g. inhibitors of sterol biosynthesis and cysteine proteases) are in the pipeline. With the availability of complete genome sequences for all three pathogens, and methods for rapid validation of targets, it is hoped that much-needed amelioration will occur soon. Financial constraints continue to represent a major hurdle to drug development. However, the appearance of not-for-profit product-development partnerships offers a new paradigm for bringing new drugs to patients.

    Treating patients undergoing chemotherapy who display findings of liver toxicity, requires a solid understanding of these medications. It is important for any clinician to have an index of suspicion for liver toxicity and be able to recognize it, even on imaging. Cancer chemotherapy has evolved, and newer medications that target cell biology have a different pattern of liver toxicity and may differ from the more traditional cytotoxic agents. There are several hepatic conditions that can result and keen clinical as well as radiographic recognition are paramount. Conditions such as sinusoidal obstructive syndrome, steatosis, and pseudocirrhosis are more commonly associated with chemotherapy. These conditions can display clinical signs of acute hepatitis, liver cirrhosis, and even liver failure. It is important to anticipate and recognize these adverse reactions and thus appropriate clinical action can be taken. Often times, patients with these liver manifestations can be managed with supportive therapies, and liver toxicity may resolve after discontinuation of chemotherapy. PMID:25320738

    Neuroblastoma is the most common extracranial childhood solid tumor. Treatment of high risk tumors require intense multicycle chemotherapies, resulting in short- and long-term toxicities. Here, we present treatment of an orthotopic neuroblastoma mouse model, with silk fibroin materials loaded with vincristine, doxorubicin or the combination as a intratumoral, sustained release system. The materials, loaded with vincristine with or without doxorubicin, significantly decreased neuroblastoma tumor growth compared to materials loaded without drug or doxorubicin only as well as intravenous (IV) drug treatment. The intratumoral drug concentration was significantly higher with intratumoral delivery versus IV. Furthermore, intratumor delivery decreased the maximum plasma concentration compared to IV delivery, reducing systemic exposure and possibly reduing long-term side effects of chemotherapy exposure. Histopathologically, tumors with remission periods >25 days before recurrence transformed from a "small-round-blue cell" (SBRC) to predominantly "large cell" neuroblastoma (LCN) histopathology, a more aggressive tumor subtype with unfavorable clinical outcomes. These results show that intratumoral chemotherapy delivery may be a treatment strategy for pediatric neuroblastoma, potentially translatable to other focal tumors types. Furthermore, this treatment modality allows for a clinically relevant mouse model of tumor transformation that may be used for studying the phenotypical tumor recurrence and developing more effective treatment strategies for recurrent tumors.

  3. Management of Chemotherapy Induced Nausea and Vomiting in Patients on Multiday Cisplatin Based Combination Chemotherapy

    2015-01-01

    Introduction of cisplatin based chemotherapy has revolutionized the treatment of germ cell tumors. A common side effect of multiday cisplatin chemotherapy is severe nausea and vomiting. Considerable progress has been made in the control of these side effects since the introduction of cisplatin based chemotherapy in the 1970s. Germ cell tumor which is a model for a curable neoplasm has also turned into an excellent testing ground to develop effective strategies to prevent chemotherapy induced nausea and vomiting (CINV) in multiday cisplatin based regimens. The use of combination of a 5-hydroxytryptamine (HT)3 receptor antagonist, a neurokinin-1 (NK1) antagonist, and dexamethasone has greatly improved our ability to prevent and control acute and delayed CINV. Mechanism and pattern of CINV with multiday chemotherapy may differ from those in single day chemotherapy and therefore efficacy of antiemetic drugs as observed in single day chemotherapy may not be applicable. There are only few randomized clinical trials with special emphasis on multiday chemotherapy. Further studies are essential to determine the efficacy, optimal dose, and duration of the newer agents and combinations in multiday cisplatin based chemotherapy. PMID:26425563

    While chemotherapeutic agents have yielded relative success in the treatment of cancer, patients are often plagued with unwanted and even debilitating side-effects from the treatment which can lead to dose reduction or even cessation of treatment. Common side effects (symptoms) of chemotherapy include (i) cognitive deficiencies such as problems with attention, memory and executive functioning; (ii) fatigue and motivational deficit; and (iii) neuropathy. These symptoms often develop during treatment but can remain even after cessation of chemotherapy, severely impacting long-term quality of life. Little is known about the underlying mechanisms responsible for the development of these behavioral toxicities, however, neuroinflammation is widely considered to be one of the major mechanisms responsible for chemotherapy-induced symptoms. Here, we critically assess what is known in regards to the role of neuroinflammation in chemotherapy-induced symptoms. We also argue that, based on the available evidence, neuroinflammation is unlikely the only mechanism involved in the pathogenesis of chemotherapy-induced behavioral toxicities. We evaluate two other putative candidate mechanisms. To this end we discuss the mediating role of damage-associated molecular patterns (DAMPs) activated in response to chemotherapy-induced cellular damage. We also review the literature with respect to possible alternative mechanisms such as a chemotherapy-induced change in the bioenergetic status of the tissue involving changes in mitochondrial function in relation to chemotherapy-induced behavioral toxicities. Understanding the mechanisms that underlie the emergence of fatigue, neuropathy, and cognitive difficulties is vital to better treatment and long-term survival of cancer patients.

      We investigated the efficacy of hepatic arterial infusion chemotherapy (HAIC) using 5-fluorouracil (5-FU) and systemic interferon (IFN)-α (HAIC-5-FU/IFN) for advanced hepatocellular carcinoma (HCC) with venous tumor thrombosis (VTT) in the hepatic vein trunk (Vv2) or inferior vena cava (Vv3).   Thirty-three patients with HCC/Vv2/3 underwent HAIC with 5-FU (500 mg/body weight/day, into hepatic artery on days 1-5 on the first and second weeks) and IFN-α (recombinant IFN-α-2b 3 000 000 U or natural IFN-α 5 000 000 U, intramuscularly on days 1, 3 and 5 of each week). Three-dimensional conformal radiotherapy (3D-CRT) was used in combination with HAIC-5-FU/IFN in 14 of 33 patients to reduce VTT.   The median survival time (MST) was 7.9 months, and 1- and 2-year survival rates were 30% and 20%, respectively. Evaluation of intrahepatic response after two cycles of HAIC-5-FU/IFN showed complete response (CR) in three (9%) and partial response (PR) in seven (21%), with an objective response rate of 30%. Multivariate analysis identified reduction of VTT (P = 0.0006), size of largest tumor (P = 0.013) and intrahepatic response CR/PR (P = 0.030) as determinants of survival. CR/PR correlated significantly with tumor liver occupying rate (P = 0.016) and hepatitis C virus Ab (P = 0.010). Reduction of VTT correlated significantly with radiotherapy (P = 0.021) and platelet count (P = 0.015). Radiotherapy-related reduction in VTT significantly improved survival of 16 patients with Vv3 and non-CR/PR response of HAIC-5-FU/IFN (P = 0.028).   As for advanced HCC with VTT of Vv2/3, HAIC-5-FU/IFN responsive patients could obtain favorable survival. Despite ineffective HAIC-5-FU/IFN, the combination with effective radiotherapy to VTT might improve patients' prognosis. © 2011 The Japan Society of Hepatology.

    Perioperative chemotherapy is a standard treatment for patients with muscle-invasive bladder carcinoma undergoing radical cystectomy; however, direct comparisons of neoadjuvant and adjuvant chemotherapy are lacking. Evidence-based data and implementation into daily clinical practice favor neoadjuvant chemotherapy; nevertheless, neoadjuvant chemotherapy is still underused in daily practice compared to adjuvant chemotherapy. If neoadjuvant chemotherapy has not been used and patients are fit enough to receive cisplatin, adjuvant chemotherapy should be considered in patients with pT3-pT4 and/or lymph node metastases.

    2016-01-01

    Chemotherapy-induced peripheral neuropathy is a common side effect of selected chemotherapeutic agents. Previous work has suggested that patients often under report the symptoms of chemotherapy-induced peripheral neuropathy and physicians fail to recognize the presence of such symptoms in a timely fashion. The precise pathophysiology that underlies chemotherapy-induced peripheral neuropathy, in both the acute and the chronic phase, remains complex and appears to be medication specific. Recent work has begun to demonstrate and further clarify potential pathophysiological processes that predispose and, ultimately, lead to the development of chemotherapy-induced peripheral neuropathy. There is increasing evidence that the pathway to neuropathy varies with each agent. With a clearer understanding of how these agents affect the peripheral nervous system, more targeted treatments can be developed in order to optimize treatment and prevent long-term side effects.
