Cancer is the most dreadful disease affecting mankind. The available treatments such as chemotherapy and radiotherapy have cytotoxic effects, which are hazardous to the normal cells of the patient, causing many unnecessary effects. This further leads to complications of the therapy, impaired health, and deterioration of quality of life, resulting in mandatory stoppage of the treatment. In the present study, the efficacy of an Ayurvedic formulation, Rasayana Avaleha, has been evaluated as an adjuvant medication to modern radiotherapy and chemotherapy. A total of 36 cancer patients were registered in this trial and were divided into two groups, group A and group B. In group A, the patients were treated with radiotherapy and chemotherapy along with adjuvant Rasayana Avaleha (RT + CT + RA), while in group B only radiotherapy and chemotherapy (RT + CT) were given, as the control group. After assessing the results, it was observed that Rasayana Avaleha gave better results in controlling the adverse effect of chemotherapy and radiotherapy in comparison with the control group. Therefore, Rasayana Avaleha has proved to be an effective adjuvant therapy in protecting patients from the adverse effects of chemotherapy and radiotherapy.

To evaluate the clinical benefit of adjuvant platinum-based chemotherapy after radical cystectomy for muscle-invasive bladder cancer in routine clinical practice. The present observational study was carried out to compare the effectiveness of adjuvant chemotherapy versus observation post-radical cystectomy in patients with clinically muscle-invasive bladder cancer. Cancer-specific survival and overall survival between the adjuvant chemotherapy group and radical cystectomy alone group were compared using Kaplan-Meier method and log-rank test. After adjusting for background factors using propensity score weighting, differences in cancer-specific survival and overall survival between these two groups were compared. Subgroup analyses by the pathological characteristics were carried out. In total, 322 patients were included in the present study. Of these, 23% received adjuvant chemotherapy post-radical cystectomy. Clinicopathological characteristics showed that patients in the adjuvant chemotherapy group were pathologically more advanced and were at higher risk than the radical cystectomy alone group. In the unadjusted population, although it is not significant, the adjuvant chemotherapy group had lower overall survival (3-year overall survival; 61.5% vs 73.6%, HR 1.33, P = 0.243, log-rank test, adjuvant chemotherapy vs radical cystectomy alone). In the weighted propensity score analysis, although it is not significant, the adjuvant chemotherapy group were superior to radical cystectomy alone groups (overall survival: HR 0.65, 95% CI 0.39-1.09, P = 0.099, log-rank test, adjuvant chemotherapy vs radical cystectomy alone). Subgroup analyses showed that adjuvant chemotherapy significantly reduced the hazard ratio of overall survival and cancer-specific survival in the ≥pT3, pN+, ly+ and v+ subgroups. Platinum-based adjuvant chemotherapy might be associated with increased cancer-specific survival and overall survival in patients with high-risk invasive bladder cancer. �

The objective of this cross-sectional study was to determine lumbar spine bone mineral density (BMD) in breast cancer patients previously treated with adjuvant chemotherapy. Sixteen of 27 patients who received adjuvant chemotherapy became permanently amenorrheic as a result of chemotherapy. BMD was measured at the lumbar spine using dual energy X-ray absorptiometry (DEXA). Chemotherapy drugs and dosages along with a history of risk factors for reduced bone density including activity level, tobacco and/or alcohol use, metabolic bone disease, family history, and hormone exposure were identified. Results showed that women who became permanently amenorrheic as a result of chemotherapy had BMD 14% lower than women who maintained menses after chemotherapy. Chemotherapy-treated women who maintained ovarian function had normal BMD. This study suggests that women who have premature menopause as a result of chemotherapy for breast cancer are at increased risk of bone loss and may be at risk for early development of osteoporosis. Women who maintain menses do not appear to be at risk for accelerated trabecular bone loss.

Two hundred and eleven patients with node-positive stage II and III breast cancer were treated with eight cycles of adjuvant chemotherapy comprising cyclophosphamide, doxorubicin and oral ftorafur (CAFt), with and without tamoxifen. All patients had undergone radical surgery, and 148 patients were treated with post-operative radiotherapy in two randomized studies. The impact of haematological toxicity of CAFt on distant disease-free (DDFS) and overall survival (OS) was recorded. Dose intensity of all given cycles (DI), dose intensity of the two initial cycles (DI2) and total dose (TD) were calculated separately for all chemotherapy drugs and were correlated with DDFS and OS. Patients with a lower leucocyte nadir during the chemotherapy had significantly better DDFS and OS (P = 0.01 and 0.04 respectively). Dose intensity of the two first cycles also correlated significantly with DDFS (P = 0.05) in univariate but not in multivariate analysis, while the leucocyte nadir retained its prognostic value. These results indicate that the leucocyte nadir during the adjuvant chemotherapy is a biological marker of chemotherapy efficacy; this presents the possibility of establishing an optimal dose intensity for each patient. The initial dose intensity of adjuvant chemotherapy also seems to be important in assuring the optimal effect of adjuvant chemotherapy. PMID:9010042

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

Adjuvant chemotherapy improves survival in patients with completely resected stage II and III NSCLC. However, its role in patients with stage IB NSCLC disease remains unclear. We evaluated the role of adjuvant chemotherapy in a large data set of patients with completely resected T2N0M0 NSCLC. Patients with pathologic stage T2N0M0 NSCLC who underwent complete (R0) resection between 2004 and 2011 were identified from the National Cancer Data Base and classified into four groups based on tumor size: 3.1 to 3.9 cm, 4 to 4.9 cm, 5 to 5.9 cm, and 6 to 7 cm. Patients who died within 1 month after their operation were excluded. Survival curves were estimated by the Kaplan-Meier product-limit method and compared by log-rank test. Among the 25,267 patients who met the inclusion criteria, there were 4996 (19.7%) who received adjuvant chemotherapy. Adjuvant chemotherapy was associated with improved median and 5-year overall survival compared with observation for all tumor size groups. In patients with T2 tumors smaller than 4 cm, adjuvant chemotherapy was associated with improved median and 5-year overall survival in univariate (101.6 versus 68.2 months [67% versus 55%], hazard ratio [HR] = 0.66, 95% confidence interval [CI]: 0.61-0.72, p < 0.0001) and multivariable analysis (HR = 0.77, 95% CI: 0.70-0.83, p < 0.001) as well as propensity-matched score (101.6 versus 78.9 months [68% versus 60%], HR = 0.75, 95% CI: 0.70-0.86; p < 0.0001). In patients with completely resected T2N0M0, adjuvant chemotherapy is associated with improved survival in all tumor size groups. The benefit in patients with tumors smaller than 4 cm strongly suggests a role for chemotherapy in this patient population and counters its current status as an exclusion criteria for adjuvant trials.

Background: Although there are controversies regarding the benefit of fluoropyrimidine-based adjuvant chemotherapy in patients with microsatellite instability–high (MSI-H) colorectal cancer (CRC), the pathologic features affecting postchemotherapeutic prognosis in these patients have not been fully identified yet. Methods: A total of 26 histopathologic and immunohistochemical factors were comprehensively evaluated in 125 stage II or III MSI-H CRC patients who underwent curative resection followed by fluoropyrimidine-based adjuvant chemotherapy. We statistically analyzed the associations of these factors with disease-free survival (DFS). Results: Using a Kaplan- Meier analysis with log-rank test, we determined that ulceroinfiltrative gross type (p=.003), pT4 (p<.001), pN2 (p=.002), perineural invasion (p=.001), absence of peritumoral lymphoid reaction (p=.041), signet ring cell component (p=.006), and cribriform comedo component (p=.004) were significantly associated with worse DFS in patients receiving oxaliplatin-based adjuvant chemotherapy (n=45). By contrast, pT4 (p<.001) and tumor budding-positivity (p=.032) were significant predictors of poor survival in patients receiving non-oxaliplatin–based adjuvant chemotherapy (n=80). In Cox proportional hazards regression model-based univariate and multivariate analyses, pT category (pT1-3 vs pT4) was the only significant prognostic factor in patients receiving non-oxaliplatin–based adjuvant chemotherapy, whereas pT category, signet ring cell histology and cribriform comedo histology remained independent prognostic factors in patients receiving oxaliplatin-based adjuvant chemotherapy. Conclusions: pT4 status is the most significant pathologic determinant of poor outcome after fluoropyrimidine-based adjuvant chemotherapy in patients with stage II/III MSI-H CRC. PMID:26148739

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

(Neo)adjuvant chemotherapy for early stage breast cancer is associated with side-effects, resulting in increased emergency department (ED) presentations. Treatment-related toxicity can affect quality of life, compromise chemotherapy delivery and treatment outcomes, and increase healthcare use. We performed a retrospective study of ED presentations in patients receiving curative chemotherapy for early breast cancer to identify factors contributing to ED presentations. Of 102 patients, 39 (38%) presented to ED within 30 days of chemotherapy, resulting in 63 ED presentations in total. Most common reasons were non-neutropenic fever (17 presentations/27%), neutropenic fever (15/24%), pain (9/14%), drug reaction (6/10%) and infection (4/6%). Factors significantly associated with ED presentation were adjuvant chemotherapy timing compared to neoadjuvant timing (P = 0.031), prophylactic antibiotics (P = 0.045) and docetaxel-containing regimen (P = 0.018). © 2018 Royal Australasian College of Physicians.

Purpose We evaluated the usefulness of the in vitro adenosine triphosphate-based chemotherapy response assay (ATP-CRA) for prediction of clinical response to fluorouracil-based adjuvant chemotherapy in stage II colorectal cancer. Materials and Methods Tumor specimens of 86 patients with pathologically confirmed stage II colorectal adenocarcinoma were tested for chemosensitivity to fluorouracil. Chemosensitivity was determined by cell death rate (CDR) of drug-exposed cells, calculated by comparing the intracellular ATP level with that of untreated controls. Results Among the 86 enrolled patients who underwent radical surgery followed by fluorouracil-based adjuvant chemotherapy, recurrence was found in 11 patients (12.7%). The CDR ≥ 20% group was associated with better disease-free survival than the CDR < 20% group (89.4% vs. 70.1%, p=0.027). Multivariate analysis showed that CDR < 20% and T4 stage were poor prognostic factors for disease-free survival after fluorouracil-based adjuvant chemotherapy. Conclusion In stage II colorectal cancer, the in vitro ATP-CRA may be useful in identifying patients likely to benefit from fluorouracil-based adjuvant chemotherapy. PMID:26511802

The aim of this multicenter trial was to evaluate the role of ovarian suppression in patients with early breast cancer previously treated with local surgery and adjuvant chemotherapy. Nine hundred and twenty-six premenopausal patients with completely resected breast cancer and either axillary node involvement or histological grade 2 or 3 tumors were randomized after surgery to adjuvant chemotherapy alone (control arm) or adjuvant chemotherapy plus ovarian suppression (ovarian suppression arm). Ovarian suppression was obtained by either radiation-induced ovarian ablation or triptorelin for 3 years. The analyses were performed with Cox models stratified by center. Median follow-up was 9.5 years. Mean age was 43 years. Ninety per cent of patients had histologically proven positive axillary nodes, 63% positive hormonal receptors and 77% had received an anthracycline-based chemotherapy regimen. Ovarian suppression was by radiation-induced ovarian ablation (45% of patients) or with triptorelin (48%). At the time of randomization, all patients had regular menses or their follicle-stimulating hormone and estradiol levels indicated a premenopausal status. The 10-year disease-free survival rates were 49% [95% confidence interval (CI) 44% to 54%] in both arms (P = 0.51). The 10-year overall survival rates were 66% (95% CI 61% to 70%) for the ovarian suppression arm and 68% (95% CI 63% to 73%) for the control arm (P = 0.19). There were no variations in the treatment effect according to age, hormonal receptor status or ovarian suppression modality. However, in patients <40 years of age and with estrogen receptor-positive tumors, ovarian suppression significantly decreased the risk of recurrence (P = 0.01). The results of this trial, after at least 10 years of follow-up, do not favor the use of ovarian suppression after adjuvant chemotherapy. The potential beneficial effect in younger women with hormono-dependent tumors should be further assessed.

A meta-analysis was performed to quantify the magnitude and nature of the association between adjuvant chemotherapy and performance on a range of cognitive domains among breast cancer patients. A total of 27 studies (14 cross-sectional, 8 both cross-sectional and prospective, and 5 prospective) were included in the analyses, involving 1562 breast cancer patients who had undergone adjuvant chemotherapy and 2799 controls that included breast cancer patients who did not receive adjuvant chemotherapy. A total of 737 effect sizes (Cohen’s d) were calculated for cross-sectional and prospective longitudinal studies separately and classified into eight cognitive domains. The mean effect sizes varied across cross-sectional and prospective longitudinal studies (ranging from −1.12 to 0.62 and −0.29 to 1.12, respectively). Each cognitive domain produced small effect sizes for cross-sectional and prospective longitudinal studies (ranging from −0.25 to 0.41). Results from cross-sectional studies indicated a significant association between adjuvant chemotherapy and cognitive impairment that held across studies with varied methodological approaches. For prospective studies, results generally indicated that cognitive functioning improved over time after receiving adjuvant chemotherapy. Greater cognitive impairment was reported in cross-sectional studies comparing chemotherapy groups with healthy control groups. Results suggested that cognitive impairment is present among breast cancer patients irrespective of a history of chemotherapy. Prospective longitudinal research is warranted to examine the degree and persisting nature of cognitive impairment present both before and after chemotherapy, with comparisons made to participants’ cognitive function prior to diagnosis. Accurate understanding of the effects of chemotherapy is essential to enable informed decisions regarding treatment and to improve quality of life among breast cancer patients. PMID:25806355

The benefit of adjuvant chemotherapy remains controversial for patients with stage IB non-small-cell lung cancer (NSCLC). This study investigated the effect of adjuvant chemotherapy and the predictors of benefit from adjuvant chemotherapy in patients with stage IB lung adenocarcinoma. A total of 243 patients with completely resected pathologic stage IB lung adenocarcinoma were included in the study. Predictors of the benefits of improved overall survival (OS) or probability of freedom from recurrence (FFR) from platinum-based adjuvant chemotherapy in patients with resected stage IB lung adenocarcinoma were investigated. Among the 243 patients, 70 (28.8%) had received platinum-based doublet adjuvant chemotherapy. A micropapillary/solid-predominant pattern (versus an acinar/papillary-predominant pattern) was a significantly worse prognostic factor for probability of FFR (p = 0.033). Although adjuvant chemotherapy (versus surgical intervention alone) was not a significant prognostic factor for OS (p = 0.303), it was a significant prognostic factor for a better probability of FFR (p = 0.029) on multivariate analysis. In propensity-score-matched pairs, there was no significant difference in OS between patients who received adjuvant chemotherapy and those who did not (p = 0.386). Patients who received adjuvant chemotherapy had a significantly better probability of FFR than those who did not (p = 0.043). For patients with a predominantly micropapillary/solid pattern, adjuvant chemotherapy (p = 0.033) was a significant prognostic factor for a better probability of FFR on multivariate analysis. Adjuvant chemotherapy is a favorable prognostic factor for the probability of FFR in patients with stage IB lung adenocarcinoma, particularly in those with a micropapillary/solid-predominant pattern.

Some patients develop recurrence after curative resection and adjuvant chemotherapy. S-1, an oral fluoropyrimidine, is one of the standard regimens in adjuvant chemotherapy, and is also used in first-line treatment for advanced/metastatic gastric cancer. It is controversial as to whether the same treatment strategy can be applied for patients who develop recurrence after adjuvant chemotherapy and those who did not receive adjuvant chemotherapy. To investigate this issue, we compared the outcomes of patients who developed recurrences after treatment with or without adjuvant chemotherapy using the results of the Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer (ACTS-GC). Patients who had confirmed recurrence in the ACTS-GC trial were analyzed. We defined 2 independent cohorts. Cohort 1 patients were divided by whether they received adjuvant chemotherapy (adjuvant S-1 group and surgery-only group). Cohort 2 patients were divided by whether they received a regimen including S-1 (IS) or not including S-1 (NIS) after recurrence. A total of 375 patients experienced recurrence (160 in the adjuvant S-1 group and 215 in the surgery-only group). In cohort 1, the median time from recurrence to death (TFRD) was 11.4 months (95% confidence interval [CI], 8.4-13.9) in the adjuvant S-1 group and 11.3 months (95% CI, 9.7-13.1) in the surgery-only group (hazard ratio [HR], 1.05; 95% CI, 0.84-1.31). In cohort 2, 292 patients received chemotherapy after recurrence and were divided into the IS (n = 189) or the NIS group (n = 103). The median TFRD was 13.9 months (95% CI, 12.7-15.6) in the IS group and 8.1 months (95% CI, 6.6-9.7) in the NIS group (HR, 0.59; 95% CI, 0.45-0.76), and there was no significant interaction between the adjuvant S-1 group and surgery-only group. Adjuvant chemotherapy with S-1 prolonged overall survival without influencing the TFRD. The same treatment strategy may be applied for patients who develop recurrence after adjuvant chemotherapy and

The aim of this study was to assess the efficacy of adjuvant TMZ chemotherapy for newly diagnosed GBM patients who were treated with surgery followed by radiotherapy alone. Between January 2003 and April 2005, 59 consecutive GBM patients underwent radiation therapy after surgical resection and subsequently received TMZ chemotherapy. For the comparative analysis, we selected 60 clinically matched GBM patients who underwent radiotherapy followed by nitrosourea-based chemotherapy (NUBC), at the same institution between June 1995 and April 2005. The study cohort was divided into two groups, those with adjuvant TMZ treatment and with NUBC. 59 patients with adjuvant TMZ treatment were assigned to the treatment group and 60 patients with NUBC to the control group. The median overall survival for the treatment group was 18.2 months (95% CI, 11.7-24.7 months), compared with the survival of 14.5 months (95% CI, 11.2-17.7 months) for the control group (p=0.019). The progression-free survival for the treatment group was 5.6 months (95% CI, 4.4-6.7 months), while the control group showed progression-free survival of 3.3 months (95% CT, 3.2-6.0 months) (p=0.030). Uni- and multivariate analysis revealed that extent of surgical resection, age > or =55 years and postoperative KPS were significantly associated with survival. Adjuvant TMZ chemotherapy provided a clinically relevant benefit of survival, as compared with NUBC. Thus, we suggest that adjuvant TMZ chemotherapy may be effective even for patients who did not receive concomitant chemoradiotherapy for GBM.

Purpose: To investigate the effects of adjuvant chemotherapy in nasopharyngeal carcinoma (NPC) patients with persistently detectable plasma Epstein-Barr virus DNA (pEBV DNA) after curative radiation therapy plus induction/concurrent chemotherapy. Methods and Materials: The study population consisted of 625 NPC patients with available pEBV DNA levels before and after treatment. Eighty-five patients with persistently detectable pEBV DNA after 1 week of completing radiation therapy were eligible for this retrospective study. Of the 85 patients, 33 were administered adjuvant chemotherapy consisting of oral tegafur-uracil (2 capsules twice daily) for 12 months with (n=4) or without (n=29) preceding intravenous chemotherapy of mitomycin-C, epirubicin, and cisplatin.more » The remaining 52 patients who did not receive adjuvant chemotherapy served as the control group. Results: Baseline patient characteristics at diagnosis (age, sex, pathologic type, performance status, T classification, N classification, and overall stage), as well as previous treatment modality, were comparable in both arms. After a median follow-up of 70 months for surviving patients, 45.5% (15 of 33 patients) with adjuvant chemotherapy and 71.2% (37 of 52 patients) without adjuvant chemotherapy experienced tumor relapses (P=.0323). There were a significant reduction in distant failure (P=.0034) but not in local or regional recurrence. The 5-year overall survival rate was 71.6% for patients with adjuvant chemotherapy and 28.7% for patients without adjuvant chemotherapy (hazard ratio 0.27; 95% confidence interval 0.17-0.55; P<.0001). Conclusions: Our retrospective data showed that adjuvant chemotherapy can reduce distant failure and improve overall survival in NPC patients with persistently detectable pEBV DNA after curative radiation therapy plus induction/concurrent chemotherapy.« less

To analyze the efficacy and toxicity of adjuvant chemotherapy followed by whole abdominal irradiation in the treatment of resectable gastric cancer with positive lymph nodes. Between 1996 and 1999, 10 patients with node-positive gastric cancer underwent complete gross resection and were treated by postoperative chemoradiotherapy. The chemotherapy regimen consisted of 5-fluorouracil, 1000 mg/m2/day as a 96-hr continuous infusion on day 1, and cisplatin, 100 mg/m2 on day 2, every 21 days. Six courses were planned. Radiotherapy was administered 3 weeks after completion of the chemotherapy protocol as a single-fraction dose of 600 cGy in a two-field (anterior and posterior) configuration. Treatment was generally well tolerated, with no treatment-related deaths. However, 9 of the 10 patients died of recurrent disease, with a median survival of 20 months (range, 7-84). Adjuvant chemotherapy with whole abdominal irradiation for gastric cancer is safe and tolerable but has no apparent effect on patient outcome. Studies in larger series are needed to evaluate the role of the approach in this disease.

Purpose Survival benefit from adjuvant chemotherapy is established for stage III colon cancer; however, uncertainty exists for stage II patients. Tumor heterogeneity, specifically microsatellite instability (MSI) which is more common in right-sided cancers, may be the reason for this observation. We examined the relationship between adjuvant chemotherapy and overall 5-year mortality for stage II colon cancer by location (right- versus left-side) as a surrogate for MSI. Methods Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified Medicare beneficiaries from 1992 to 2005 with AJCC stage II (n=23,578) and III (n=17,148) primary adenocarcinoma of the colon who underwent surgery for curative intent. Overall 5-year mortality was examined with Kaplan-Meier survival analysis and Cox proportional hazards regression with propensity score weighting. Results Eighteen percent (n=2,941) of stage II patients with right-sided cancer and 22% (n=1,693) with left-sided cancer received adjuvant chemotherapy. After adjustment, overall 5-year survival benefit from chemotherapy was observed only for stage III patients (right-sided: HR 0.64; 95% CI, 0.59–0.68, p<0.001 and left-sided: HR 0.61; 95% CI, 0.56–0.68, p<0.001). No survival benefit was observed for stage II patients with either right-sided (HR 0.97; 95% CI, 0.87–1.09, p=0.64) or left-sided cancer (HR 0.97; 95% CI, 0.84–1.12, p=0.68). Conclusions Among Medicare patients with stage II colon cancer, a substantial number receive adjuvant chemotherapy. Adjuvant chemotherapy did not improve overall 5-year survival for either right- or left-sided colon cancers. Our results reinforce existing guidelines and should be considered in treatment algorithms for older adults with stage II colon cancer. PMID:24643898

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

Despite a large number of clinical trials having been conducted to assess the efficacy of adjuvant chemotherapy after surgery for various cancers, whether it is best to use this treatment remains a generally contentious issue for many common cancers. The purpose of this study was to ascertain whether any general conclusions can be drawn about the efficacy or inefficacy of this treatment within different cancer classifications. Meta-analyses of randomized, controlled trials (RCTs) of adjuvant chemotherapy after surgery were synthesized over as many types of cancer as possible. Data sources were Medline, Embase, and the Cochrane library. Eligible meta-analyses were meta-analyses of RCTs for any type of cancer that compared surgery followed by adjuvant chemotherapy with surgery followed by no adjuvant chemotherapy. The literature search found 25 meta-analyses for 15 cancer types that satisfied the criteria necessary for detailed analysis within this study. The estimates of relative risk for all cause mortality were reported as being less than one (indicating adjuvant chemotherapy is beneficial) by all meta-analyses apart from a meta-analysis for colorectal cancer metastasized to the liver. Moreover, 15 of these meta-analyses also reported that the 95% confidence interval for this relative risk is less than one (indicating statistical significance at the 5% level). The results for all cancer types included in this study except for cancer metastasized to the liver can be thought of as supporting each other through the idea of there being a common treatment effect or at least a common range of effect across all (or most) of these cancer types. For example, with regard to cancer types where the evidence in favor of adjuvant chemotherapy after surgery is only moderately strong, the results of this study may encourage more clinicians to regard the use of this treatment as standard practice.

We report the recruitment rate, reasons for and factors influencing non-participation, and descriptive results of a randomized controlled trial of two different exercise programs for patients with colon cancer undergoing adjuvant chemotherapy. Participants were randomized to a low-intensity, home-based program (Onco-Move), a moderate- to high-intensity, combined supervised resistance and aerobic exercise program (OnTrack), or Usual Care. Non-participants provided reasons for non-participation and were asked to complete a questionnaire assessing behavioral and attitudinal variables. Trial participants completed performance-based and self-reported outcome measures prior to randomization, at the end of chemotherapy, and at the 6-month follow-up. Twenty-three of 63 referred patients agreed to participate in the trial. All 40 non-participants provided reasons for non-participation. Forty-five percent of the non-participants completed the questionnaire. Those who did not want to exercise had higher fatigue scores at baseline and a more negative attitude toward exercise. Compliance to both programs was high and no adverse events occurred. On average, the colon cancer participants were able to maintain or improve their physical fitness levels and maintain or decrease their fatigue levels during chemotherapy and follow-up. Recruitment of patients with colon cancer to a physical exercise trial during adjuvant chemotherapy proved to be difficult, underscoring the need to develop more effective strategies to increase participation rates. Both home-based and supervised programs are safe and feasible in patients with colon cancer undergoing chemotherapy. Effectiveness needs to be established in a larger trial.

Clinical guidelines recommend adjuvant chemotherapy for high-risk patients with Stage II-III colorectal cancer. However, chemotherapeutic administration rates differ significantly between hospitals. We assessed the prognostic benefit of adjuvant chemotherapy in patients with Stage IIb/c colorectal cancer, and the prognostic impact of interhospital variations in the administration of adjuvant chemotherapy for Stage II-III colorectal cancer. We conducted a multicentre, retrospective study of 17 757 patients with Stage II-III colorectal cancer treated between 1997 and 2008 in 23 hospitals in Japan. Hospitals were classified as high-rate (rate > 42.8%) or low-rate (rate ≤ 42.8%), chemotherapy prescribing clinics. The 5-year overall survival (OS) of patients with Stage II-III colorectal cancer receiving adjuvant chemotherapy was significantly higher than for those not receiving adjuvant chemotherapy (85.7% vs 79.2%, P < 0.01 and 79.9% vs 72.5%, P < 0.01, respectively). For patients with Stage II disease, adjuvant chemotherapy was an independent factor for longer OS (P < 0.01, hazard ratio = 0.71). Both adjuvant chemotherapy and high-rate hospital independently improved OS for patients with Stage III colorectal cancer (both P < 0.01; hazard ratio = 0.68 and 0.87, respectively). Significant prognostic benefit was found for patients with Stage IIb/c colorectal cancer who received adjuvant chemotherapy, with patients who were treated in hospitals with high adjuvant chemotherapy rates demonstrating better prognoses.

By and large, data about adjuvant chemotherapy for breast cancer in the Middle East are lacking. Retrospective analysis of prospectively captured data from a main referral center in the Kingdom of Saudi Arabia (KSA) may shed some light on the clinicopathological features and survival of patients offered adjuvant chemotherapy in a similar population in that part of the world. Data on patients with invasive breast cancer (Stages I to IIIA) seen between 1992 and the end of 2001 and who received adjuvant chemotherapy were analyzed. A total of 780 patients were considered eligible and constitute the basis of this report. The median age +/- SD of the 780 patients was 42 +/- 9.6 yr. The majority of patients were younger than 50 yr (78%) and premenopausal (83%). Ten percent, 69%, and 21% of patients had Stage I, II, and IIIA, respectively. Patients expressed relatively high prevalence of adverse clinicopathological characteristics. Most patients (523 patients, 67%) received anthracyclines-containing adjuvant chemotherapy, 610 patients (78%) received adjuvant radiotherapy, and 296 (38%) received adjuvant tamoxifen. At a median follow-up of 42 mo (95% CI, 38.1-62.8 mo), the median overall (OS) and disease-free survival (DFS) were not reached; however, the 5-yr actuarial survival was estimated as 74% and 59%, respectively. Cox proportional regression hazard model identified positive axillary nodal status, and positive vascular invasion are the only variables that influenced OS adversely. The model also distinguished the same variables plus negative estrogen receptor status as covariates with negative effect on DFS. In conclusion, this series of 780 predominantly young patients with breast cancer receiving adjuvant chemotherapy highlighted the disease patterns and survival outcome in the KSA. The current series is significant being one of the few reports about adjuvant chemotherapy experience in a developing country and certainly the first from that part of the world.

Although chemotherapy is used routinely in pediatric medulloblastoma (MB) patients, its benefit for adult MB is unclear. We evaluated the survival impact of adjuvant chemotherapy in adult MB. Using the National Cancer Data Base, we identified patients aged 18 years and older who were diagnosed with MB in 2004-2012 and underwent surgical resection and adjuvant craniospinal irradiation (CSI). Patients were divided into those who received adjuvant CSI and chemotherapy (CRT) or CSI alone (RT). Predictors of CRT compared with RT were evaluated with univariable and multivariable logistic regression. Survival analysis was limited to patients receiving CSI doses between 23 and 36 Gy. Overall survival (OS) was evaluated using the Kaplan-Meier estimator, log-rank test, multivariable Cox proportional hazards modeling, and propensity score matching. Of the 751 patients included, 520 (69.2%) received CRT, and 231 (30.8%) received RT. With median follow-up of 5.0 years, estimated 5-year OS was superior in patients receiving CRT versus RT (86.1% vs 71.6%, P < .0001). On multivariable analysis, after controlling for risk factors, CRT was associated with superior OS compared with RT (HR: 0.53; 95%CI: 0.32-0.88, P = .01). On planned subgroup analyses, the 5 year OS of patients receiving CRT versus RT was improved for M0 patients (P < .0001), for patients receiving 36 Gy CSI (P = .0007), and for M0 patients receiving 36 Gy CSI (P = .0008). This national database analysis demonstrates that combined postoperative chemotherapy and radiotherapy are associated with superior survival for adult MB compared with radiotherapy alone, even for M0 patients who receive high-dose CSI. © The Author(s) 2016.

Low rates of adjuvant chemotherapy use are frequently reported in older women with early breast cancer. One of the reasons for this may be the risk of febrile neutropaenia or the perception that older patients will probably not complete the chemotherapy course prescribed. There are no data regarding these adverse outcomes in routine clinical practice. We identified 128 patients aged 70 years or over who received neoadjuvant or adjuvant chemotherapy for early breast cancer in seven UK cancer centres between 2006 and 2012. Data were collected regarding standard clinical and pathological variables and treatment toxicity and outcomes. Twenty-four patients (19%) had an episode of febrile neutropaenia. Overall, 27 patients (21%) did not complete their planned therapy. Chemotherapy discontinuation was more common in those patients with an episode of febrile neutropaenia (46% versus 16%, P = 0.004). Thirty patients (23%) were admitted with chemotherapy-related complications. There were no treatment-related deaths. The rates of febrile neutropaenia and treatment discontinuation are high in women aged 70 years or over receiving adjuvant chemotherapy for breast cancer. Close attention should be paid to the choice or regimen and the use of supportive therapies in this patient population. Copyright © 2014 The Royal College of Radiologists. Published by Elsevier Ltd.

Patients with colorectal cancer with synchronous liver metastases may undergo a staged or a simultaneous resection. This study aimed to determine whether the time to adjuvant chemotherapy was delayed in patients undergoing a simultaneous resection. A retrospective cohort study was conducted between 2005 and 2016. The primary outcome was time to adjuvant chemotherapy. A multivariate linear regression was conducted to ascertain the adjusted effect of a simultaneous versus a staged approach on time to adjuvant chemotherapy. A total of 155 patients were included. A total of 127 patients underwent a staged resection, whereas 28 patients underwent a simultaneous resection. Age, sex, and American Society of Anesthesiologists class as well tumor, node, metastasis stage, tumor location, and number and size of metastases were not significantly different between the groups. The median time to adjuvant chemotherapy was 70 and 63 days for the staged and simultaneous groups, respectively (P = .27). Multivariate analysis did not demonstrate an increased propensity for prolonged time to chemotherapy after simultaneous resection (rate ratio: 0.97, 95% CI: 0.71-1.32, P = .84). There were no significant differences in the length of stay, complications, overall survival, and disease-free survival between the groups (P > .05). This study demonstrated that simultaneous resection does not result in significant delay of adjuvant chemotherapy compared with a staged approach. © 2018 Wiley Periodicals, Inc.

Background & Aims 5-FU-based adjuvant chemotherapy does not increase survival times of patients with colorectal tumors with microsatellite instability. We determined the response of patients with colorectal tumors with the CpG island methylator phenotype (CIMP) to 5-FU-based therapy. Methods We analyzed a population-based cohort of 302 patients with colorectal cancer (CRC) for a median follow-up time of 50.7 months. CIMP status was determined by analysis of the CACNAG1, SOCS1, RUNX3, NEUROG1, and MLH1 promoters; tumors were considered to be CIMP-positive (CIMP+) if at least 3 promoters were methylated. Results Tumors from 29.5% (89/302) of patients were CIMP+; this did not influence disease-free survival (log rank=.26). Of tumors of TNM stages II–III (n=196), 32.7% were CIMP+. Among patients with CRC stages II–III who did not receive adjuvant 5-FU chemotherapy, those with CIMP+ tumors had longest times of disease-free survival (log rank=.04); patients with CIMP+ tumors who received chemotherapy had shorter times of disease-free survival (log rank=0.02). In patients with CIMP-negative tumors, adjuvant 5-FU chemotherapy significantly increased time of disease-free survival (log-rank=.00001). However, in patients with CIMP+ tumors, adjuvant 5-FU chemotherapy did not affect time of disease-free survival (log rank=.7). Multivariate analysis showed a significant, independent interaction between 5-FU treatment and CIMP status (hazard ratio [HR]=0.6; 95% confidence interval [CI], .5–.8). Among patients with CIMP+ tumors, adjuvant chemotherapy was not an independent predictor of outcome (HR=0.8; 95% CI, 0.3–2.0). In patients who did not receive adjuvant 5-FU chemotherapy, CIMP status was the only independent predictor of survival (HR=2.0; 95% CI, 1.1–3.8) Conclusion Patients with CIMP+ colorectal tumors do not benefit from 5-FU–based adjuvant chemotherapy.

Adjuvant chemotherapy for soft tissue sarcoma.

PubMed

Casali, Paolo G

2015-01-01

Adjuvant chemotherapy is not standard treatment in soft tissue sarcoma (STS). However, when the risk of relapse is high, it is an option for shared decision making with the patient in conditions of uncertainty. This is because available evidence is conflicting, even if several randomized clinical trials have been performed for 4 decades and also have been pooled into meta-analyses. Indeed, available meta-analyses point to a benefit in the 5% to 10% range in terms of survival and distant relapse rate. Some local benefit also was suggested by some trials. Placing chemotherapy in the preoperative setting may help gain a local advantage in terms of the quality of surgical margins or decreased sequelae. This may be done within a personalized approach according to the clinical presentation. Attempts to personalize treatment on the basis of the variegated pathology and molecular biology of STS subgroups are ongoing as well, according to what is done in the medical treatment of advanced STS. Thus, decision making for adjuvant and neoadjuvant indications deserves personalization in clinical research and in clinical practice, taking profit from all multidisciplinary clinical skills available at a sarcoma reference center, though with a degree of subjectivity because of the limitations of available evidence.

With the increasing incidence of breast cancer worldwide, in particular in southeast Asia (including Korea), and the common use of anthracyclines in the adjuvant and metastatic settings, the occurrence of Hepatitis B virus (HBV) reactivation may develop in this patient population. The use of prophylactic antiviral agents in cancer patients may result in a reduced HBV exacerbation. The purpose of the current study was to assess the efficacy of prophylactic lamivudine in reducing the incidence and severity of HBV reactivation in post-operative breast cancer patients undergoing adjuvant doxorubicin-containing chemotherapy. The medical records of patients undergoing anthracycline-based adjuvant chemotherapy at Samsung Medical Center between January 2001 and September 2008 were reviewed. From the database, 1912 breast cancer patients who had received anthracycline-based adjuvant chemotherapy were identified. Of 131 patients who were HBV surface antigen positive, 55 and 76 did and did not receive prophylactic lamivudine, respectively. In all, 30 patients (23%) developed hepatitis during doxorubicin-containing adjuvant chemotherapy. Of the 30 patients, 5 (9%) were in the prophylactic lamivudine group and 25 (33%) in the control group (P=0.001). In the prophylactic lamivudine group, there was significantly less HBV reactivation (1 patient (2%) vs 20 patients (16%); P=0.002), less disruption of chemotherapy (7 vs 14%; P=0.04), and less severe hepatitis (0 vs 17%; P=0.002). Prophylactic lamivudine significantly reduced the incidence and severity of HBV reactivation in breast cancer patients undergoing anthracycline-based adjuvant chemotherapy.

The role of adjuvant chemotherapy for non-small-cell lung cancer (NSCLC) stage I patients with tumors size ≥4 cm is not well established in the elderly. We identified 3289 patients with stage I NSCLC (T2N0M0 and tumor size ≥4 cm) who underwent lobectomy from the Surveillance, Epidemiology and End Results (SEER)-Medicare linked database diagnosed from 1992 to 2009. Overall survival and rates of serious adverse events (defined as those requiring admission to hospital) were compared between patients treated with resection alone, platinum-based adjuvant chemotherapy, or postoperative radiation (PORT) with or without adjuvant chemotherapy. Propensity scores for receiving each treatment were calculated and survival analyses were conducted using inverse probability weights based on the propensity score. Overall, 84% patients were treated with resection alone, 9% received platinum-based adjuvant chemotherapy, and 7% underwent PORT with or without adjuvant chemotherapy. Adjusted analysis showed that adjuvant chemotherapy [hazard ratio (HR), 0.82; 95% confidence interval (CI) 0.68-0.98] was associated with improved survival compared with resection alone. Conversely, the use of PORT with or without adjuvant chemotherapy (HR 1.91; 95% CI 1.64-2.23) was associated with worse outcomes. Patients receiving adjuvant chemotherapy had more serious adverse events compared with those treated with resection alone, with neutropenia (odds ratio, 21.2; 95% CI 5.8-76.6) being most significant. No significant difference was observed in rates of fever, cytopenias, nausea, and renal dysfunction. Platinum-based adjuvant chemotherapy is associated with reduced mortality and increased serious adverse events in elderly patients with stage I NSCLC and tumor size ≥4 cm. © The Author 2015.

Adjuvant chemotherapy decisions in early breast cancer are complex. The 21-gene assay can potentially aid such decisions, but costs US $4175 per patient. Adjuvant! Online is a freely available decision aid. We evaluate the cost-effectiveness of using the 21-gene assay in conjunction with Adjuvant! Online, and of providing adjuvant chemotherapy conditional upon risk classification. A probabilistic Markov decision model simulated risk classification, treatment, and the natural history of breast cancer in a hypothetical cohort of 50-year-old women with lymph node-negative, estrogen receptor- and/or progesterone receptor-positive, human epidermal growth factor receptor 2/neu-negative early breast cancer. Cost-effectiveness was considered from an Ontario public-payer perspective by deriving the lifetime incremental cost (2012 Canadian dollars) per quality-adjusted life-year (QALY) for each strategy, and the probability each strategy is cost-effective, assuming a willingness-to-pay of $50,000 per QALY. The 21-gene assay has an incremental cost per QALY in patients at low, intermediate, or high Adjuvant Online! risk of $22,440 (probability cost-effective 78.46%), $2,526 (99.40%), or $1,111 (99.82%), respectively. In patients at low (high) 21-gene assay risk, adjuvant chemotherapy increases (reduces) costs and worsens (improves) health outcomes. For patients at intermediate 21-gene assay risk and low, intermediate, or high Adjuvant! Online risk, chemotherapy has an incremental cost per QALY of $44,088 (50.59%), $1,776 (77.65%), or $1,778 (82.31%), respectively. The 21-gene assay appears cost-effective, regardless of Adjuvant! Online risk. Adjuvant chemotherapy appears cost-effective for patients at intermediate or high 21-gene assay risk, although this finding is uncertain in patients at intermediate 21-gene assay and low Adjuvant! Online risk. Copyright © 2013 International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc. All rights

2004-01-01

Although hepatotoxicity has been rarely reported during adjuvant chemotherapy in breast cancer patients, we observed a high frequency in our patients who were also taking alternative agents. We therefore sought to determine the association between hepatotoxicity and alternative agents during adjuvant chemotherapy in breast cancer patients. All breast cancer patients were treated with the same chemotherapeutic regimen and had normal baseline liver function test (LFT). LFT was checked repeatedly during each cycle of chemotherapy. Patients showing LFT abnormalities were asked about use of alternative agents, and, after the end of chemotherapy, a questionnaire was administered to each patient on their use of alternative agents. Of 178 patients, 65 (36.5%) admitted using alternative therapy, and significantly more patients in this group developed LFT abnormalities (37/65, 56.9%) than those who denied taking alternative therapy (25/113, 22.1%, p=0.001). Although LFT abnormalities were mild to moderate and normalized in most patients after cessation of alternative agents, it remained a serious problem in one patient. In conclusion, alternative therapy may be one of the etiologies for abnormal LFT in breast cancer patients receiving adjuvant chemotherapy. PMID:15201506

Weight gain is a well-known and unwanted complication of adjuvant chemotherapy in breast cancer. We observed that the female Turkish cancer patients frequently gain weight with adjuvant treatment of breast cancer and planned to examine the magnitude of this problem in early breast cancer patients treated at our hospital. A total of 176 early breast cancer patients who received their adjuvant systemic therapy in Marmara University Hospital between 2003 and 2007 are included in the study. We recorded their weight before and after chemotherapy and also a year after chemotherapy to find out whether the change with weight is transitory. We have also recorded demographic information, including the educational level, menopausal status, the type of chemotherapy or hormonal treatment administered stage of disease, marital status, occupation and the underlying diseases to analyze the relationship between change in weight and these parameters. Median age of patients was 53 and 72% of patients were postmenopausal. Educational level was equally distributed for primary education (27%), high school (40%), and university (33%). The majority of the patients (76%) was married, had two children (69%) and was housewife (60%). Family history of any cancer was high (32%). Most of the patients had stage II cancer (56%), received anthracyclines+/- taxane based chemotherapy (98%) and had no underlying disease (68%). The majority also did not smoke (73%) or drink alcohol (93%). A total of 67% and 72% patients gained weight upon completion and one year after completion of chemotherapy. Mean weight before the chemotherapy, upon completion of chemotherapy and one year after completion of chemotherapy were 68.9 kg, 70.6 kg (P = 0.000) and 71.9 kg (P = 0.000) respectively. Mean body mass index was 27.1 at baseline, 27.8 upon completion of chemotherapy (P = 0.000) and 28.3 one year after completion of chemotherapy (P = 0.000).

To estimate the modifying effect of age on the survival benefit associated with adjuvant chemotherapy receipt in elderly patients with a diagnosis of Stage III colon cancer. Observational, retrospective cohort study using two samples: an overall sample of 7,182 patients to provide externally valid analyses and a propensity score-matched sample of 3,016 patients to provide more internally valid analyses by reducing the presence of treatment endogeneity. An interval-censored survival model with a complementary log-log link was used. Hazard ratios and 95% confidence intervals were obtained for all regressions. Data from the National Cancer Institute's Surveillance, Epidemiology and End Results database and the linked Medicare enrollment and claims database were used. Selected patients were aged 66 and older and had a diagnosis of Stage III colon cancer. Patients were followed from surgery to time of death or censorship. The outcome was colon cancer-specific death during the follow-up period. Receipt of adjuvant chemotherapy was measured according to the presence of a claim for 5-fluorouracil or leucovorin within 6 months after surgery. All elderly patients had a significant survival benefit associated with adjuvant chemotherapy receipt, although the survival benefit of adjuvant chemotherapy was not uniform across all age groups. These findings have important clinical and policy implications for the risk-benefit calculation induced by treatment in older patients with Stage III colon cancer. The results suggest that there is a benefit from chemotherapy, but the benefit is lower with older age.

To investigate the effects of adjuvant chemotherapy in nasopharyngeal carcinoma (NPC) patients with persistently detectable plasma Epstein-Barr virus DNA (pEBV DNA) after curative radiation therapy plus induction/concurrent chemotherapy. The study population consisted of 625 NPC patients with available pEBV DNA levels before and after treatment. Eighty-five patients with persistently detectable pEBV DNA after 1 week of completing radiation therapy were eligible for this retrospective study. Of the 85 patients, 33 were administered adjuvant chemotherapy consisting of oral tegafur-uracil (2 capsules twice daily) for 12 months with (n=4) or without (n=29) preceding intravenous chemotherapy of mitomycin-C, epirubicin, and cisplatin. The remaining 52 patients who did not receive adjuvant chemotherapy served as the control group. Baseline patient characteristics at diagnosis (age, sex, pathologic type, performance status, T classification, N classification, and overall stage), as well as previous treatment modality, were comparable in both arms. After a median follow-up of 70 months for surviving patients, 45.5% (15 of 33 patients) with adjuvant chemotherapy and 71.2% (37 of 52 patients) without adjuvant chemotherapy experienced tumor relapses (P=.0323). There were a significant reduction in distant failure (P=.0034) but not in local or regional recurrence. The 5-year overall survival rate was 71.6% for patients with adjuvant chemotherapy and 28.7% for patients without adjuvant chemotherapy (hazard ratio 0.27; 95% confidence interval 0.17-0.55; P<.0001). Our retrospective data showed that adjuvant chemotherapy can reduce distant failure and improve overall survival in NPC patients with persistently detectable pEBV DNA after curative radiation therapy plus induction/concurrent chemotherapy.

Objective: To explore the role of adjuvant chemotherapy for patients with ypT0-2N0 rectal cancer treated by preoperative chemoradiation therapy (PCRT) and radical resection. Patients and Methods: A national consortium of 10 institutions was formed, and patients with ypT0-2N0 mid- and low-rectal cancer after PCRT and radical resection from 2004 to 2009 were included. Patients were categorized into 2 groups according to receipt of additional adjuvant chemotherapy: Adj CTx (+) versus Adj CTx (−). Propensity scores were calculated and used to perform matched and adjusted analyses comparing relapse-free survival (RFS) between treatment groups while controlling for potential confounding. Results: A totalmore » of 1016 patients, who met the selection criteria, were evaluated. Of these, 106 (10.4%) did not receive adjuvant chemotherapy. There was no overall improvement in 5-year RFS as a result of adjuvant chemotherapy [91.6% for Adj CTx (+) vs 87.5% for Adj CTx (−), P=.18]. There were no differences in 5-year local recurrence and distant metastasis rate between the 2 groups. In patients who show moderate, minimal, or no regression in tumor regression grade, however, possible association of adjuvant chemotherapy with RFS would be considered (hazard ratio 0.35; 95% confidence interval 0.14-0.88; P=.03). Cox regression analysis after propensity score matching failed to show that addition of adjuvant chemotherapy was associated with improved RFS (hazard ratio 0.81; 95% confidence interval 0.39-1.70; P=.58). Conclusions: Adjuvant chemotherapy seemed to not influence the RFS of patients with ypT0-2N0 rectal cancer after PCRT followed by radical resection. Thus, the addition of adjuvant chemotherapy needs to be weighed against its oncologic benefits.« less

We sought to review the current evidence in order to test the efficacy of adjuvant chemotherapy in improving disease-free survival in patients affected by early stage uterine leiomyosarcoma. On July 2016, literature was searched in order to identify trials comparing different postoperative adjuvant strategies for patients diagnosed with early stage uterine leiomyosarcoma. Our analysis included 360 patients: 145 (40%), 53 (15%), and 155 (43%) had chemotherapy (with or without radiotherapy), radiotherapy, and observation, respectively. Seven (2%) patients who had radiotherapy with or without chemotherapy were excluded from further analysis in order to reduce risk of biases. Administration of chemotherapy (with or without radiotherapy) did not improve outcomes in comparison to observation (OR: 0.79 (95%CI: 0.48, 1.29)), or radiotherapy (OR: 0.90 (95%CI: 0.42, 1.94)). Loco-regional recurrence rate was similar comparing patients undergoing chemotherapy (with or without radiotherapy) with having observation alone (OR: 0.84 (95%CI: 0.44, 1.60)). Similarly, pooled results suggested that chemotherapy administration did not affect distant recurrence rate in comparison to no chemotherapy (OR: 0.80 (95%CI: 0.50, 1.28)), and observation alone (OR: 0.99 (95%CI: 0.60, 1.64)). However, patients undergoing chemotherapy (with or without radiotherapy) experienced a trend towards lower risk of developing distant recurrences (OR: 0.49 (95%CI: 0.24, 1.03)) and a higher risk of developing loco-regional recurrences (OR: 3.45 (95%CI: 1.02, 11.73)) than patients undergoing radiotherapy. In early stage uterine leiomyosarcoma, the role of adjuvant chemotherapy remains unclear. Owing to the high recurrence rate, even in the early stage of disease, further innovative therapeutic strategies have to be tested. Copyright © 2016 Elsevier Inc. All rights reserved.

Severe neutropenia is a common dose-limiting side effect of adjuvant breast cancer chemotherapy. We aimed to test the hypothesis that weak circadian rhythm is associated with an increased risk of neutropenia using a cohort study. We consecutively recruited 193 breast cancer patients who received adjuvant chemotherapy (5-fluorouracil, epirubicin, and cyclophosphamide followed by docetaxel; doxorubicin and cyclophosphamide; docetaxel and cyclophosphamide). Participants wore a wrist actigraph continuously for 168 h at the beginning of chemotherapy. Values of percent rhythm and double amplitude below medians represented weak circadian rhythm. Mesor measured the mean activity level and acrophase symboled the peak time of the rhythm. We used Cox proportional hazard regression model to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) of grade 4 neutropenia and febrile neutropenia in relation to actigraphy-derived parameters. Low levels of percent rhythm (HR:2.59, 95% CI 1.50-4.72), double amplitude (HR:2.70, 95% CI 1.51-4.85), and mesor (HR: 2.48, 95% CI 1.44-4.29) were positively associated with the risk of grade 4 neutropenia during chemotherapy. Low levels of percent rhythm (HR: 2.41, 95% CI 1.02-5.69) and double amplitude (HR:2.49, 95% CI 1.05-5.90) were also associated with increased risks of febrile neutropenia. The HRs for acrophase were not statistically significant. This study provides the first epidemiological evidence that increased risks of grade 4 neutropenia and febrile neutropenia are associated with weak circadian rhythm among adjuvant breast cancer patients. The results suggest that circadian rhythm might be one potential target for the prevention of chemotherapy-induced neutropenia among cancer patients.

Aim The aim of our study was to evaluate stage III colon cancer patients discussed at a multidisciplinary team meeting to identify reasons for clinicians not recommending adjuvant chemotherapy and reasons for patients declining recommended chemotherapy. Methods A retrospective, single institution Australian study was conducted on all surgically managed stage III colon cancer patients diagnosed at the regional cancer centre at Toowoomba Hospital between July 2010 and December 2014. Reasons why adjuvant chemotherapy was not recommended by the multidisciplinary team or following referral to a medical oncologist and patients' reasons for refusing chemotherapy despite medical oncology recommendation were determined. Results One hundred and nine patients were suitable for evaluation. Overall, 72 (66.1%) received adjuvant chemotherapy. Chemotherapy was not recommended in 25 (23.4%) of patients, with the majority (68%) having more than one cited reason. Multiple comorbidities and advanced age were the most common reasons for non-recommendation ( p < 0.01). Age alone was not a reason for not recommending chemotherapy. Twelve (11%) patients declined offered chemotherapy. The reasons for refusal were not detailed in the majority of patient charts (63.6%). Travel distance was not a factor in accepting or refusing chemotherapy. Conclusion Discussion at a multidisciplinary team meeting facilitates the identification of patients unsuitable for adjuvant treatment. The reasons for declining offered chemotherapy need to be assessed fully to ensure that patients' treatment preferences are balanced against the proven benefits of chemotherapy. Attendance at a regional cancer centre provides the opportunity for high standard care in the management of stage III colon cancer.

Anthracycline-based chemotherapies for breast cancer are known to adversely affect patients' quality of life (QOL) and immune function. For that reason, adjuvants that improve those impairments are required. A randomized double-blind study was conducted to evaluate the effectiveness of Lentinula edodes mycelia extract (LEM), which is an oral biological response modifier (BRM) medicine for cancer patients as such an adjuvant. A total of 47 breast cancer patients who were scheduled to receive postoperative adjuvant anthracycline-based chemotherapy, i.e., 5-fluorouracil (5-FU) + cyclophosphamide + epirubicin (FEC regimen), 5-FU + cyclophosphamide + doxorubicin/pirarubicin (FAC regimen), cyclophosphamide + doxorubicin/pirarubicin (AC regimen) and cyclophosphamide + epirubicin (EC regimen), were entered in the study. The patients were randomly divided into either an LEM or a placebo tablet group; the tablets were orally ingested daily over 2 courses of each therapy. In the placebo group, the total scores for QOL were lower on day 8 of the second course of chemotherapy compared with the baseline scores, whereas in the LEM group the scores had not decreased. In the placebo group, the QOL functional well-being score was lower on day 8 after both the first and second courses of chemotherapy compared with the baseline score, but it had not decreased in the LEM group. Evaluation of immunological parameters indicated that an increase in the proportion of regulatory T cells to peripheral blood CD4 + cells tended to be inhibited in the LEM group compared with the placebo group. Oral LEM that was coadministered with anthracycline-based chemotherapies was useful for maintaining patients' QOL and immune function. Thus, LEM appears to be a useful oral adjuvant for patients receiving anthracycline-based chemotherapy.

We studied elderly Medicare enrollees newly diagnosed with early-stage breast cancer to examine the association between adjuvant chemotherapy and acute kidney injury (AKI). Using the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database, we conducted a retrospective cohort study including women diagnosed with stages I-III breast cancer at ages 66-89 years between 1992 and 2007. We performed one-to-one matching on time-dependent propensity score on the day of adjuvant chemotherapy initiation within 6 months after the first cancer-directed surgery based on the estimated probability of chemotherapy initiation at each day for each patient, using a Cox proportional hazards model. We estimated the cumulative incidence of AKI using Kaplan-Meier methods. We used Cox proportional hazards models to evaluate the association between chemotherapy and the risk of AKI, and compared the risk among major chemotherapy types. The study included 28,048 women. The 6-month cumulative incidence of AKI was 0.80% for chemotherapy-treated patients, compared with 0.30% for untreated patients (P < 0.001). Adjuvant chemotherapy was associated with a nearly threefold increased risk of AKI [hazard ratio (HR) 2.73; 95% CI 1.8-4.1]. Compared with anthracycline-based chemotherapy, the HRs (95% CIs) were 1.66 (0.94-2.91), 0.88 (0.53-1.47), and 1.15 (0.57-2.32) for taxane-based, CMF, and other chemotherapy, respectively. Our findings showed that adjuvant chemotherapy was associated with increased risk of AKI in elderly women diagnosed with early-stage breast cancer. The risk seemed to vary by regimen type, but the differences were not statistically significant.

Is febrile neutropenia prophylaxis with granulocyte-colony stimulating factors economically justified for adjuvant TC chemotherapy in breast cancer?

PubMed

Skedgel, Chris; Rayson, Daniel; Younis, Tallal

2016-01-01

Febrile neutropenia (FN) during adjuvant chemotherapy is associated with morbidity, mortality risk, and substantial cost, and subsequent chemotherapy dose reductions may result in poorer outcomes. Patients at high risk of, or who develop FN, often receive prophylaxis with granulocyte colony-stimulating factors (G-CSF). We investigated whether different prophylaxis strategies with G-CSF offered favorable value-for-money. We developed a decision model to estimate the short- and long-term costs and outcomes of a hypothetical cohort of women with breast cancer receiving adjuvant taxotere + cyclophosphamide (TC) chemotherapy. The short-term phase estimated upfront costs and FN risks with adjuvant TC chemotherapy without G-CSF prophylaxis (i.e., chemotherapy dose reductions) as well as with secondary and primary G-CSF prophylaxis strategies. The long-term phase estimated the expected costs and quality-adjusted life years (QALYs) for patients who completed adjuvant TC chemotherapy with or without one or more episodes of FN. Secondary G-CSF was associated with lower costs and greater QALY gains than a no G-CSF strategy. Primary G-CSF appears likely to be cost-effective relative to secondary G-CSF at FN rates greater than 28%, assuming some loss of chemotherapy efficacy at lower dose intensities. The cost-effectiveness of primary vs. secondary G-CSF was sensitive to FN risk and mortality, and loss of chemotherapy efficacy following FN. Secondary G-CSF is more effective and less costly than a no G-CSF strategy. Primary G-CSF may be justified at higher willingness-to-pay thresholds and/or higher FN risks, but this threshold FN risk appears to be higher than the 20% rate recommended by current clinical guidelines.

Background: We assessed the sensitivity to adjuvant chemotherapy in cell cycle checkpoint kinase 2 (CHEK2) vs non-CHEK2 breast cancer patients by comparing the contralateral breast cancer incidence and distant disease-free and breast cancer-specific survival between both groups, stratified for adjuvant chemotherapy. Methods: One Dutch hereditary non-BRCA1/2 breast cancer patient cohort (n=1220) and two Dutch cohorts unselected for family history (n=1014 and n=2488, respectively) were genotyped for CHEK2 1100delC. Hazard ratios for contralateral breast cancer, distant disease-free and breast cancer-specific death for mutation carriers vs noncarriers were calculated using the Cox proportional hazard method, stratified for adjuvant chemotherapy. Results: The CHEK2 mutation carriers (n=193) had an increased incidence of contralateral breast cancer (multivariate hazard ratio 3.97, 95% confidence interval 2.59–6.07). Distant disease-free and breast cancer-specific survival were similar in the first 6 years in mutation carriers compared with noncarriers, but diverted as of 6 years after breast cancer diagnosis (multivariate hazard ratios and 95% confidence intervals 2.65 (1.79–3.93) and 2.05 (1.41–2.99), respectively). No significant interaction between CHEK2 and adjuvant chemotherapy was observed. Conclusions: The CHEK2 1100delC-associated breast cancer is associated with a higher contralateral breast cancer rate as well as worse survival measures beyond 6 years after diagnosis. No differential sensitivity to adjuvant chemotherapy was observed in CHEK2 patients. PMID:24918820

A 74-year-old woman was diagnosed as having transverse colon cancer after diagnosis of nephrotic syndrome caused by membranous nephropathy. Although she had hypoproteinemia and hypoalbuminemia, we judged that she had no major nutritional problem. In previous, similar case reports, the use of human serum albumin and fresh-frozen plasma was suggested to be important to avoid complications in the perioperative period. Thus, we used the same in our patient in the perioperative period. In addition, we paid special attention to perioperative nutrition management and used total parenteral nutrition in perioperative period. We performed laparoscopic assisted right hemicolectomy. On the 15th day after the surgical resection, the patient was discharged without any problems. We considered that postoperative adjuvant chemotherapy with XELOX (CapeOX)should be performed because the TNM pathological stage was pStage III b. Regarding adjuvant chemotherapy for gastrointestinal cancer with nephrotic syndrome, no previous reports detailed the indications for postoperative adjuvant chemotherapy. Upon introduction of adjuvant chemotherapy, we determined adaptation in accordance with the general adaptation criteria. While observing the patient's progress with a nephrologist, we safely completed the scheduled 8 courses adjuvant chemotherapy.

Temozolomide (TMZ) is now standard adjuvant therapy in combination with radiotherapy for patients with newly diagnosed malignant glioma. Treatment-related myelodysplastic syndrome and acute treatment-related leukemia (t-AML) associated with TMZ chemotherapy for patients with glioma is quite a rare complication. A 43-year-old man with an anaplastic astrocytoma received radiation therapy synchronized with ranimustine and adjuvant TMZ chemotherapy for 15 cycles. Close follow-up magnetic resonance imaging of the head during TMZ chemotherapy showed no evidence of tumor progression. One year after the completion of TMZ chemotherapy, a bone-marrow aspiration was performed because the patient's white blood cell count decreased. He was diagnosed with t-AML based on the bone marrow examination, and then he was referred to the cancer center for the treatment of t-AML. In this case study, we continued adjuvant TMZ therapy beyond the recommended 6 cycles. Currently, there is no consensus as to how long the adjuvant TMZ therapy should be continued for the treatment of residual tumor showing no apparent interval change. A new decision-making tool to assess the clinical benefits against the side effects for long-term adjuvant TMZ therapy is needed. Copyright © 2017 Elsevier Inc. All rights reserved.

Breast cancer patients younger than 55 completed a questionnaire on psychosocial factors and physical side effects shortly after diagnosis and 9 to 15 months after diagnosis. Those who had used adjuvant chemotherapy were more likely than those who had not to report physical side effects; there was little difference in psychosocial factors. Recent users were more likely than ex-users to report physical side effects, difficulties with domestic chores, and improvement in psychosocial factors. PMID:21229020

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

To describe the tolerability of two chemotherapy regimens, gemcitabine and cisplatin (GC) and methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) for adjuvant treatment of patients with locally advanced urothelial cancer after radical cystectomy. The USC Department of Urology bladder cancer database was searched for subjects who received adjuvant chemotherapy following cystectomy for transitional cell carcinoma with extravesical and/or lymph node involvement, yielding 187 cases. Clinical details regarding toxicity, number of cycles administered, and cancer outcome were analyzed. The majority of subjects had lymph node involvement (70%). Sixty-eight percent of subjects received MVAC and 32% received GC, the latter regimen was predominant after 2000. Fifty-six percent of subjects received all four planned cycles (51% GC and 58% MVAC). With a median follow-up of 11.2 years (range 1.9-19.6), 96 patients (51%) have suffered a relapse, with no significant difference between chemotherapy regimens. Median time to recurrence for the population was 3.7 years and median overall survival is 4.6 years (3.0-9.3). The median time from recurrence to death was 6.7 months and was not significantly different between MVAC and GC. Both MVAC and GC are tolerated after cystectomy for advanced urothelial carcinoma. A significant proportion of high-risk patients survive, free of disease, beyond 10 years. At recurrence, patients previously treated with adjuvant chemotherapy have a survival that appears much shorter than patients who develop metastases in the absence of this exposure, suggesting resistance to salvage chemotherapy.

The purpose of this study was to evaluate the efficacy and toxicity of a third-generation chemotherapy regimen in the adjuvant setting to radically operated patients with gastric cancer. This proposed new adjuvant regimen was also compared with a consecutive retrospective cohort of patients treated with the classic McDonald regimen. Starting in 2006, a non-randomized prospective phase II study was conducted at the Institute of Oncology of Cluj-Napoca on 40 patients with stage IB-IV radically resected gastric adenocarcinoma. These patients were administered a chemotherapy regimen already considered to be standard treatment in the metastatic setting: ECX (epirubicin, cisplatin, xeloda) and were compared to a retrospective control group consisting of 54 patients, treated between 2001 and 2006 according to McDonald's trial. In a previous paper, we reported toxicities and the possible predictive factors for these toxicities; in the present article, we report on the results concerning predictive factors on overall survival (OS) and disease free survival (DFS). The proposed ECX treatment was not less effective than the standard suggested by McDonald's trial. Age was an independent prognostic factor in multivariate analysis. N3 stage was an independent prognostic factor for OS and DFS. N ratio >70% was an independent predictive factor for OS and locoregional disease control. The resection margins were independent prognostic factors for OS and DFS. The proposed treatment is not less effective compared with the McDonald's trial. Age was an independent prognostic factor in multivariate analysis. N3 stage represented an independent prognostic factor and N ratio >70% was a predictive factor for OS and DFS. The resection margins were proven to be independent prognostic factors for OS and DFS.

The National Institute for Health and Clinical Excellence (NICE) recommended the Oncotype DX ® Breast Recurrence Score ® (RS) assay as an option for informing adjuvant chemotherapy decisions in node-negative, oestrogen receptor (ER)+, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer assessed to be at intermediate risk of recurrence based on clinicopathological factors. We evaluated the impact of RS testing on adjuvant chemotherapy decision-making in routine clinical practice in a UK Cancer Network. RS testing was performed in 201 females with newly diagnosed, ER+, HER2-negative, invasive breast cancer who underwent breast surgery with curative intent, were calculated to have a >3% overall survival benefit at 10 years from adjuvant chemotherapy based on PREDICT, and were considered for adjuvant chemotherapy. The impact of RS testing on adjuvant treatment decisions/associated cost was assessed. In all patients, the multi-disciplinary team recommended chemotherapy but the RS result allowed 127/201 patients (63.2%) to avoid unnecessary adjuvant chemotherapy. Amongst ER+, HER2-negative, node-negative patients (eligible for Oncotype DX testing in UK guidelines), 60.3% were spared chemotherapy. In node-positive patients, the assay reduced the use of chemotherapy by 69.2%. The use of RS testing to guide treatment in these 201 patients was associated with significant cost saving (when considering the cost of RS testing for all patients plus chemotherapy and its associated cost for 74 patients). Incorporating RS testing into routine clinical practice for selected node-negative and node-positive breast cancer patients significantly reduces the use of chemotherapy (p < 0.001) with its associated morbidity and costs.

2016-03-01

There is no widely accepted standard of care for canine anal sac apocrine gland adenocarcinoma (ASAGAC). Surgery alone is inadequate in many cases, but the benefit of adjuvant chemotherapy is not well established. The primary objective of this retrospective study was to evaluate the role of carboplatin chemotherapy in the post-operative management of ASAGAC. Seventy-four dogs with naturally occurring ASAGAC underwent surgery. Forty-four dogs received adjuvant carboplatin and 30 did not. Median overall survival (OS) was 703 days. Median time to progression (TTP) was 384 days. Only primary tumour size and lymph node metastasis at diagnosis significantly impacted the outcome. Differences in OS and TTP, between the dogs that received adjuvant carboplatin and those that did not, failed to reach statistical significance. Treatment of progressive disease, whilst not limited to chemotherapy, significantly prolonged the survival. This study shows that adjuvant carboplatin chemotherapy is well tolerated and may have a role in the management of dogs with ASAGAC. © 2013 John Wiley & Sons Ltd.

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

The aim of the study was to determine the association between adjuvant chemotherapy for breast cancer and menopausal symptoms, sexual function, and quality of life. Participants attended a menopause clinic with a dedicated service for cancer survivors at a large tertiary women's hospital. Information about breast cancer treatments including adjuvant chemotherapy was collected from medical records. Menopausal symptoms were recorded with the Greene Climacteric Scale and Functional Assessment of Cancer Therapy, Breast Cancer, and Endocrine Symptom Subscales. Sexual symptoms were recorded using Fallowfield's Sexual Activity Questionnaire. Quality of life was measured with Functional Assessment of Cancer Therapy scales. The severity of vasomotor, psychological, or sexual symptoms (apart from pain) did not differ between those who had received adjuvant chemotherapy (n = 339) and other breast cancer survivors (n = 465). After adjustment for current age, time since menopause, and current use of antiestrogen endocrine therapy, the risk of "severe pain" with sexual intercourse was twice as common after chemotherapy (31.6% vs 20.0%, odds ratio [OR] 2.18, 95% CI 1.25-3.79). Those treated with chemotherapy were more likely to report "severe problems" with physical well-being (OR 1.92, 95% CI 1.12-3.28) and lower breast cancer-specific quality of life (OR 1.89 95% CI 1.13-3.18), but did not differ in other quality of life measures. In this large study of breast cancer patients presenting to a specialty menopause clinic, previous chemotherapy was not associated with current vasomotor or psychological symptoms. Severe pain with intercourse was significantly more common in those treated with adjuvant chemotherapy.

Adjuvant chemotherapy and anti-estrogenic therapy can result in decreased volume of the contralateral breast, following mastectomy for the treatment of breast cancer. However, no data on the effect of adjuvant therapy on contralateral breast volume have previously been reported. We aimed to evaluate the extent to which adjuvant therapy and differences in breast density contribute to decreased breast volume. We conducted a prospective cohort study, selecting 40 nonconsecutive patients who underwent immediate breast reconstruction with mastectomy and expander insertion followed by expander replacement. We measured the contralateral breast volume before each procedure. The extent of the change was analyzed with respect to adjuvant therapy and breast density measured by preoperative mammography. The greatest decrease in breast volume was 135.1 cm 3 . The decrease in breast volume was significantly larger in the adjuvant therapy (+) group, particularly in patients with high breast density, than in the adjuvant therapy (-) group. Significant differences between the chemotherapy (+), tamoxifen (+) group and the chemotherapy (-), tamoxifen (+) group were not found. Breast density scores had a range of 2.0-3.3 (mean: 2.8). In breast reconstruction, particularly when performed in one stage, preoperative mammography findings are valuable to plastic surgeons, and possible decreases in the contralateral breast volume due to adjuvant therapy, particularly in patients with high breast density, should be considered carefully.

The role of chemotherapy in high-risk soft tissue sarcoma is controversial. Though many patients undergo initial curative resection, distant metastasis is a frequent event, resulting in 5-year overall survival rates of only 50-60%. Neo-adjuvant and adjuvant chemotherapy (CTX) has been applied to achieve pre-operative cytoreduction, assess chemosensitivity, and to eliminate occult metastasis. Here we report on the results of our non-randomized phase II study on neo-adjuvant treatment for high-risk STS. Patients with potentially curative high-risk STS (size ≥ 5 cm, deep/extracompartimental localization, tumor grades II-III [FNCLCC]) were included. The protocol comprised 4 cycles of neo-adjuvant chemotherapy (EIA, etoposide 125 mg/m(2) iv days 1 and 4, ifosfamide 1500 mg/m2 iv days 1 - 4, doxorubicin 50 mg/m(2) day 1, pegfilgrastim 6 mg sc day 5), definitive surgery with intra-operative radiotherapy, adjuvant radiotherapy and 4 adjuvant cycles of EIA. Between 06/2005 and 03/2010 a total of 50 subjects (male = 33, female = 17, median age 50.1 years) were enrolled. Median follow-up was 30.5 months. The majority of primary tumors were located in the extremities or trunk (92%), 6% originated in the abdomen/retroperitoneum. Response by RECIST criteria to neo-adjuvant CTX was 6% CR (n = 3), 24% PR (n = 12), 62% SD (n = 31) and 8% PD (n = 4). Local recurrence occurred in 3 subjects (6%). Distant metastasis was observed in 12 patients (24%). Overall survival (OS) and disease-free survival (DFS) at 2 years was 83% and 68%, respectively. Multivariate analysis failed to prove influence of resection status or grade of histological necrosis on OS or DFS. Severe toxicities included neutropenic fever (4/50), cardiac toxicity (2/50), and CNS toxicity (4/50) leading to CTX dose reductions in 4 subjects. No cases of secondary leukemias were observed so far. The current protocol is feasible for achieving local control rates, as well as OS and DFS comparable to previously published

Adjuvant chemotherapy improves survival after curative intent resection for localized pancreatic adenocarcinoma (PDAC). Given the differences in perioperative morbidity, we hypothesized that patients undergoing distal partial pancreatectomy (DPP) would receive adjuvant therapy more often those undergoing pancreatoduodenectomy (PD). The National Cancer Data Base (2004-2012) identified patients with localized PDAC undergoing DPP and PD, excluding neoadjuvant cases, and factors associated with receipt of adjuvant therapy were identified. Overall survival (OS) was analyzed using multivariable Cox proportional hazards regression. Overall, 13,501 patients were included (DPP, n = 1933; PD, n = 11,568). Prognostic characteristics were similar, except DPP patients had fewer N1 lesions, less often positive margins, more minimally invasive resections, and shorter hospital stay. The proportion of patients not receiving adjuvant chemotherapy was equivalent (DPP 33.7%, PD 32.0%; p = 0.148). The type of procedure was not independently associated with adjuvant chemotherapy (hazard ratio 0.96, 95% confidence interval 0.90-1.02; p = 0.150), and patients receiving adjuvant chemotherapy had improved unadjusted and adjusted OS compared with surgery alone. The type of resection did not predict adjusted mortality (p = 0.870). Receipt of adjuvant chemotherapy did not vary by type of resection but improved survival independent of procedure performed. Factors other than type of resection appear to be driving the nationwide rates of post-resection adjuvant chemotherapy in localized PDAC.

What is the role of neoadjuvant chemotherapy, radiation, and adjuvant treatment in resectable esophageal cancer?

The majority of patients with operable esophageal cancers present with locally advanced disease, for which surgical resection as a sole treatment modality has been historically associated with poor survival. Even following radical resection, most of these patients will eventually succumb to their disease due to distant metastasis. For this reason, there has been intense interest in the role of neoadjuvant therapy. Neoadjuvant therapy primarily consists of either chemotherapy, radiation therapy, or a combination of the two. Multiple studies of variable scope, design, and patient characteristics have been conducted to determine whether neoadjuvant therapy is warranted, and-if so-what is the best modality of treatment. Despite nearly three decades of study, decisions regarding neoadjuvant therapy for esophageal cancer remain controversial. Regardless, the available evidence provided by large, prospective studies supports preoperative chemotherapy as opposed to surgery alone. Therefore, in our opinion, there is no longer any question as to whether induction therapy is appropriate for locally advanced esophageal cancer. Less clear, however, is the evidence that the addition of radiation to chemotherapy in the preoperative setting is superior to neoadjuvant chemotherapy alone. Our group generally advocates for neoadjuvant chemotherapy alone followed by radical esophageal resection. The data for adjuvant therapy are soft, and particularly troubling is the high rate of treatment drop out in trials studying adjuvant therapy. Therefore, we strongly prefer neoadjuvant chemotherapy and reserve adjuvant chemotherapy for those rare, highly selected patients-patients with T1 tumors, for example-who do not receive neoadjuvant treatment and are found to have occult nodal disease at the time of surgery.

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

We assessed the sensitivity to adjuvant chemotherapy in cell cycle checkpoint kinase 2 (CHEK2) vs non-CHEK2 breast cancer patients by comparing the contralateral breast cancer incidence and distant disease-free and breast cancer-specific survival between both groups, stratified for adjuvant chemotherapy. One Dutch hereditary non-BRCA1/2 breast cancer patient cohort (n=1220) and two Dutch cohorts unselected for family history (n=1014 and n=2488, respectively) were genotyped for CHEK2 1100delC. Hazard ratios for contralateral breast cancer, distant disease-free and breast cancer-specific death for mutation carriers vs noncarriers were calculated using the Cox proportional hazard method, stratified for adjuvant chemotherapy. The CHEK2 mutation carriers (n=193) had an increased incidence of contralateral breast cancer (multivariate hazard ratio 3.97, 95% confidence interval 2.59-6.07). Distant disease-free and breast cancer-specific survival were similar in the first 6 years in mutation carriers compared with noncarriers, but diverted as of 6 years after breast cancer diagnosis (multivariate hazard ratios and 95% confidence intervals 2.65 (1.79-3.93) and 2.05 (1.41-2.99), respectively). No significant interaction between CHEK2 and adjuvant chemotherapy was observed. The CHEK2 1100delC-associated breast cancer is associated with a higher contralateral breast cancer rate as well as worse survival measures beyond 6 years after diagnosis. No differential sensitivity to adjuvant chemotherapy was observed in CHEK2 patients.

Importance The current staging system of gastric cancer is not adequate for defining a prognosis and predicting the patients most likely to benefit from chemotherapy. Objective To construct a survival prediction model based on specific tumor and patient characteristics that enables individualized predictions of the net survival benefit of adjuvant chemotherapy for patients with stage II or stage III gastric cancer. Design, Setting, and Participants In this multicenter retrospective analysis, a survival prediction model was constructed using data from a training cohort of 746 patients with stage II or stage III gastric cancer who satisfied the study’s inclusion criteria and underwent surgery between January 1, 2004, and December 31, 2012, at Nanfang Hospital in Guangzhou, China. Patient and tumor characteristics were included as covariates, and their association with overall survival and disease-free survival with and without adjuvant chemotherapy was assessed. The model was internally validated for discrimination and calibration using bootstrap resampling. To externally validate the model, data were included from a validation cohort of 973 patients with stage II or stage III gastric cancer who met the inclusion criteria and underwent surgery at First Affiliated Hospital in Guangzhou, China, and at West China Hospital of Sichuan Hospital in Chendu, China, between January 1, 2000, and June 30, 2009. Data were analyzed from July 10, 2016, to September 1, 2016. Main Outcomes and Measures Concordance index and decision curve analysis for each measure associated with postoperative overall survival and disease-free survival. Results Of the 1719 patients analyzed, 1183 (68.8%) were men and 536 (31.2%) were women and the median (interquartile range) age was 57 (49-66) years. Age, location, differentiation, carcinoembryonic antigen, cancer antigen 19-9, depth of invasion, lymph node metastasis, and adjuvant chemotherapy were significantly associated with overall survival

How chemotherapy affects carcinoma genomes is largely unknown. Here we report whole-exome and deep sequencing of 30 paired oesophageal adenocarcinomas sampled before and after neo-adjuvant chemotherapy. Most, but not all, good responders pass through genetic bottlenecks, a feature associated with higher mutation burden pre-treatment. Some poor responders pass through bottlenecks, but re-grow by the time of surgical resection, suggesting a missed therapeutic opportunity. Cancers often show major changes in driver mutation presence or frequency after treatment, owing to outgrowth persistence or loss of sub-clones, copy number changes, polyclonality and/or spatial genetic heterogeneity. Post-therapy mutation spectrum shifts are also common, particularly C>A and TT>CT changes in good responders or bottleneckers. Post-treatment samples may also acquire mutations in known cancer driver genes (for example, SF3B1, TAF1 and CCND2) that are absent from the paired pre-treatment sample. Neo-adjuvant chemotherapy can rapidly and profoundly affect the oesophageal adenocarcinoma genome. Monitoring molecular changes during treatment may be clinically useful.

Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) have distinct clinical, pathologic, and genomic characteristics. The objective of the current study was to compare the relative impact of adjuvant chemotherapy on the survival of patients with ILC versus those with IDC. Women with estrogen receptor (ER)-positive, human epidermal growth factor receptor 1 (HER2) -negative, stage I/II IDC and ILC who received endocrine therapy were identified from the 2000 to 2014 California Cancer Registry. Patient, tumor, and treatment characteristics were collected. Ten-year overall survival (OS) was estimated using the Kaplan-Meier method and Cox proportional-hazards modeling. In total, 32,997 women with IDC and 4638 with ILC were identified. The receipt of chemotherapy significantly decreased during the study for both subtypes. For patients with IDC, the 10-year OS rate was 95% among those who received endocrine therapy alone versus 93% (P < .01) among those who received endocrine therapy plus chemotherapy. For patients with ILC, the 10-year OS rate was 94% among those who received endocrine therapy alone versus 92% (P < .01) among those who received endocrine therapy plus chemotherapy. After adjusting for patient and treatment factors, adjuvant chemotherapy was significantly associated with a decreased 10-year hazard of death for patients with IDC (hazard ratio, 0.83; 95% confidence interval, 0.74-0.92). In contrast, adjuvant chemotherapy was not independently associated with the adjusted 10-year hazard of death for patients with ILC (hazard ratio, 1.14; 95% confidence interval, 0.90-1.46). Adjuvant chemotherapy was not associated with improved OS for patients with ER-positive, HER2-negative, stage I/II ILC. Avoidance of ineffective chemotherapy will markedly reduce the adverse effects and economic burden of breast cancer treatment for a large proportion of patients with breast cancer.

In Japan, S-1 adjuvant chemotherapy for 1 year is the standard of care for the treatment of stage II and III patients under 80 years old with gastric cancer after curative operation. However, the feasibility of S-1 chemotherapy in patients over 80 years old has not yet been elucidated. To clarify the current treatment situation and feasibility of S-1 treatment in patients over 80 years old, a questionnaire survey of the patients treated from January 2011 to December 2012 was conducted at 58 member institutions of the Stomach Cancer Study Group of the JCOG (Japan Clinical Oncology Group). Gastrectomy was performed in 15,573 patients of all ages, and 1,660 (10.7%) patients were over 80 years of age. Of these elderly patients, 661 (4.2%) were diagnosed as stage II and III. While S-1 adjuvant chemotherapy was recommended to 248 (37.5%) of the stageII/III patients, only 99 (15.0%) of them actually received S-1. Interestingly, the creatinine clearance rate was between 30 and 80 mL/min in 87 (87.9%) of the patients suggesting that S-1 dose modification should be considered. Moreover, S-1 compliance was poor in patients with more than 15% body weight loss. In general practice, surgery alone can be regarded as the standard of care for stage II and III gastric cancer patients over 80 years old. The feasibility and efficacy of S-1 adjuvant chemotherapy should be elucidated in a randomized control trial considering the vulnerabilities of the elderly.

Chemotherapy-induced immune suppression has mainly been studied in patients with advanced cancer, but the influence of chemotherapy on the immune system in early stage cancer patients has so far not been studied systematically. The aim of the present study was to monitor the immune system during anthracycline- and taxane-based adjuvant chemotherapy in early stage breast cancer patients, to assess the impact of circulating tumor cells on selected immune parameters and to reveal putative angiogenic effects of circulating endothelial cells. Peripheral blood samples from 20 early stage breast cancer patients were analyzed using a flow cytometric multi-color of antibodies to enumerate lymphocyte and dendritic cell subsets, as well as endothelial and tumor cells. An enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of various serological factors. During chemotherapy, all immunological parameters and angiogenesis surrogate biomarkers showed significant decreases. The numbers of circulating tumor cells showed significant inverse correlations with the numbers of T helper cells, a lymphocyte subset directly related to effective anti-tumor responses. Reduced T helper cell numbers may contribute to systemic immunosuppression and, as such, the activation of dormant tumor cells. From our results we conclude that adjuvant chemotherapy suppresses immune function in early stage breast cancer patients. In addition, we conclude that the presence of circulating tumor cells, defined as pan-cytokeratin(+), CD326(+), CD45(-) cells, may serve as an important indicator of a patient's immune status. Further investigations are needed to firmly define circulating tumor cells as a predictor for the success of breast cancer adjuvant chemotherapy.

European guidelines recommend adjuvant chemotherapy for stage III colon cancer but not for stage II. To determine the extent to which adjuvant chemotherapy was used in Italy and France. A common retrospective database of 2186 colon cancers diagnosed between 2003 and 2005 was analysed according to age, stage and presenting features. 38.9% of patients with stage II and 64.6% with stage III received chemotherapy in Italy, 21.7% and 65.1% in France. For stage II, the association between country and chemotherapy was only significant in patients diagnosed out of emergency (ORItaly/France: 3.05 [2.12-4.37], p<0.001) whereas patients diagnosed in emergency were as likely to receive chemotherapy in both countries. For stage III, there was a trend to a higher administration of chemotherapy for elderly patients in France compared to Italy. French patients were more likely than Italian to receive chemotherapy (OR: 1.91[1.32-2.78], p=0.001). Chemotherapy for stage III colon cancer was as extensively used in Italy as in France for young patients. Its administration could be increased in patients over 75. Stage II patients with a lower risk of relapse received chemotherapy more often in Italy than in France. Copyright © 2013 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Background Uterine carcinosarcomas are uncommon with about 35% not confined to the uterus at diagnosis. The survival of patients with advanced uterine carcinosarcoma is poor with pattern of failure indicating greater likelihood of upper abdominal and distant metastatic recurrence. Objectives To evaluate the effectiveness and safety of radiotherapy and/or systemic chemotherapy in the management of stage III-IV persistent or recurrent uterine carcinosarcoma. Search methods We searched the Cochrane Gynaecological Cancer Group Trials Register, CENTRAL, The Cochrane Library 2010, Issue 2, MEDLINE and EMBASE to May 2010. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Selection criteria Randomised controlled trials comparing adjuvant radiotherapy and/or chemotherapy in women with uterine carcinosarcoma. Data collection and analysis We independently abstracted data and assessed risk of bias. We pooled hazard ratios (HRs) for overall and progression-free survival and risk ratios (RRs) comparing adverse events in women who received radiotherapy and/or chemotherapy in meta-analyses. Main results Three trials (579 women, of whom all were assessed at the end of the trials) met the inclusion criteria. Two trials (373 women with stage III-IV persistent or recurrent disease) found that women who received combination therapy had a significantly lower risk of death and disease progression than women who received single agent ifosfamide. There was no statistically significant difference in all reported adverse events, with the exception of nausea and vomiting, which affected significantly more women in the combination therapy group than in the ifosamide group. One trial found no statistically significant difference in the risk of death and disease progression in women who received whole abdominal irradiation and chemotherapy, after adjustment for age and FIGO stage (HR = 0.71, 95

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

It would also appear from several of these reports that not only is the adjuvant use of these chemotherapeutic agents indicated, but that the preoperative use of these agents has had significant advantages. The neoadjuvant chemotherapy begins the essential systemic chemotherapy at a very early stage, allows histologic assessment of treatment effect, permits altering drug regimens postoperative, and in many reported trials has allowed less than amputative surgery (limb salvage) to be performed. Finally, close follow-up of patients with osteosarcoma has therapeutic value.(ABSTRACT TRUNCATED AT 400 WORDS)

The 21-gene recurrence score (RS) predicts outcome and benefit from adjuvant chemotherapy benefit in breast cancer patients treated with adjuvant endocrine therapy. In the NSABP B-28 study, we evaluated the 21-gene RS for its prognostic impact and its ability to predict benefit from paclitaxel (P) in node-positive, estrogen receptor-positive (ER+) breast cancer patients treated with adjuvant chemotherapy plus tamoxifen. The B-28 trial compared doxorubicin/cyclophosphamide (AC) with AC followed by P in 3060 patients. Tamoxifen for 5 years was also given to patients > 50 years and those < 50 years with ER+ and/or progesterone receptor-positive (PR+) tumors. The present study includes 1065 ER-positive, tamoxifen-treated patients with RS assessment. Median follow-up time was 11.2 years. In univariate analyses, RS was a significant predictor of outcome. In multivariate analyses, RS remained a significant independent predictor of outcome beyond clinico-pathologic factors, age, and type of surgery (p < 0.001). In the study population (n = 1065), the disease-free survival (DFS) hazard ratio (HR) with adding P to AC was 0.87 (95% CI 0.72-1.05; p = 0.14). RS was not a significant predictor of P benefit: for DFS, HRs for adding P to AC in RS low, intermediate, and high subgroups were 1.01 (95% CI 0.69-1.47; p = 0.99), 0.84 (95% CI 0.62-1.14; p = 0.26), and 0.81 (95% CI 0.60-1.10; p = 0.21), respectively (interaction p = 0.64). Similar findings were observed for the other study endpoints. RS maintains significant prognostic impact in ER-positive, node-positive patients treated with adjuvant chemotherapy plus tamoxifen. However, RS did not significantly predict benefit from adding paclitaxel to AC chemotherapy. (Trial Registration: PDQ: NSABP-B-28).

　Adjuvant cisplatin-vinorelbine chemotherapy has been shown to be effective in patients with completely resected non-small cell lung cancer (NSCLC) in several Phase III trials, but not yet in the Japanese population. Pharmacists are expected to assist patients with completion of adjuvant chemotherapy. The aim of this retrospective study was to evaluate the compliance with and safety of adjuvant cisplatin-vinorelbine chemotherapy in Japanese patients and to evaluate the contribution of pharmacists to completion of treatment. Thirty-four patients with NSCLC who received adjuvant cisplatin-vinorelbine chemotherapy at Kyorin University Hospital between January 2006 and June 2015 were reviewed. The treatment schedule comprised cisplatin 80 mg/m 2 on day 1 and vinorelbine 25 mg/m 2 on days 1 and 8 every 3 weeks. Four 3-week cycles were planned. A pharmacist provided guidance to all patients and monitored them for adverse effects thereafter. The pharmacist intervened with advice to doctors as necessary. The 4 cycles were administered in 67.6% of cases. There were no treatment-related deaths. The main grade 3 or 4 toxicities were neutropenia (76.5%) and anorexia (38.2%). The most common reason for discontinuation and dose reduction was anorexia. There were 56 instances of pharmacist intervention. In total, 96.4% of the pharmacist interventions were implemented by doctors, which included administration of an antiemetic on 15 occasions and hot fomentation for prevention of vasculitis on 7 occasions. Adjuvant cisplatin-vinorelbine chemotherapy was tolerated by most patients but was discontinued because of adverse events in some. Pharmacist intervention aids completion of planned chemotherapy and management of treatment-related adverse events.

Due to high survival rates and the relatively small benefit of adjuvant therapy, the application of personalized medicine (PM) through risk stratification is particularly beneficial in early breast cancer (BC) to avoid unnecessary harms from treatment. The new 21-gene assay (OncotypeDX, ODX) is a promising prognostic score for risk stratification that can be applied in conjunction with Adjuvant!Online (AO) to guide personalized chemotherapy decisions for early BC patients. Our goal was to evaluate risk-group specific cost effectiveness of adjuvant chemotherapy for women with early stage BC in Austria based on AO and ODX risk stratification. A previously validated discrete event simulation model was applied to a hypothetical cohort of 50-year-old women over a lifetime horizon. We simulated twelve risk groups derived from the joint application of ODX and AO and included respective additional costs. The primary outcomes of interest were life-years gained, quality-adjusted life-years (QALYs), costs and incremental cost-effectiveness (ICER). The robustness of results and decisions derived were tested in sensitivity analyses. A cross-country comparison of results was performed. Chemotherapy is dominated (i.e., less effective and more costly) for patients with 1) low ODX risk independent of AO classification; and 2) low AO risk and intermediate ODX risk. For patients with an intermediate or high AO risk and an intermediate or high ODX risk, the ICER is below 15,000 EUR/QALY (potentially cost effective depending on the willingness-to-pay). Applying the AO risk classification alone would miss risk groups where chemotherapy is dominated and thus should not be considered. These results are sensitive to changes in the probabilities of distant recurrence but not to changes in the costs of chemotherapy or the ODX test. Based on our modeling study, chemotherapy is effective and cost effective for Austrian patients with an intermediate or high AO risk and an intermediate or high

Most stage II or III colorectal cancer patients are receiving nowadays a 4 to 6-month course of adjuvant chemotherapy. However, delays between cycles, reductions in the doses of chemotherapy drugs, or even permanent omissions of chemotherapy cycles might take place due to side effects or patient's preference. We examined the impact of these treatment modifications on recurrence-free survival (RFS) and overall survival (OS). We retrospectively collected data from colorectal cancer patients who had received adjuvant chemotherapy in our Department. Patients were categorized in five groups based on whether they had or not delays between chemotherapy cycles, dose reductions, and permanent omissions of chemotherapy cycles. Three-year RFS and OS of the five different groups were compared using the log-rank test and the Sidak approach. Five hundred and eight patients received treatment. Twenty seven percent of the patients had the full course of chemotherapy; the others had delays, dose reductions, or early termination of the treatment. No statistically significant differences were observed in 3-year RFS and OS between the five groups. A trend for worse RFS was noticed with early termination of treatment. A similar trend was also noticed for OS but only for stage II patients. In colorectal cancer patients, receiving adjuvant chemotherapy, delays between chemotherapy cycles, dose reductions of chemotherapy drugs, or even early termination of the treatment course do not seem to have a negative impact in 3-year RFS and OS; however, due to the trend of worse RFS in patients receiving shorter courses of chemotherapy, further studies are needed.

Decisions about adjuvant chemotherapy in older women with early stage breast cancer (EBC) are often challenging. Uncertainty about benefits due to limited data about treatment efficacy and outcomes complicates decision making. This qualitative study explored older patients' experiences and preferences towards information giving and ultimate decisions about adjuvant chemotherapy. Clinicians from 24 UK breast cancer teams reported on adjuvant chemotherapy decisions for women aged ≥70 years with EBC from April 2010 to December 2011. Women who were offered chemotherapy were invited to participate in structured interviews. Self-reported quality of life (QoL) and functional ability were assessed. Qualitative methods were used to identify themes associated with information giving and decision making. A total of 58/95 eligible women (61%) participated. Median age was 73 years (range 70-83). Mean total scores for QoL and functional ability were average. The majority of women preferred to make their treatment decisions collaboratively with a clinician (59%) or on their own (19%). The main reasons influencing decisions to accept chemotherapy were categorised as prevention of recurrence and clinician recommendation. Side effects, length of treatment, impact on QoL, low survival benefits and clinician recommendation influenced decisions to decline chemotherapy. The majority (80%) were satisfied with information provision, the communication with their clinician and explanation of treatment. Older women with EBC preferred to be involved in clinical decision making. Clinician recommendation plays a significant role in either accepting or declining chemotherapy. Well-informed decision making and effective communication between clinicians, older women and their family members are therefore important. Copyright © 2013 John Wiley & Sons, Ltd.

BACKGROUND We recently reported in a prospective randomized trial that ultra-staging of patients with colon cancer is associated with significantly improved disease-free survival (DFS) compared with conventional staging. That trial did not control for lymph node (LN) number or adjuvant chemotherapy use. STUDY DESIGN The current international prospective multi-center cooperative group trial (NCI Clinical Trial NCT00949312), “Ultra-staging in Early Colon Cancer” (UECC), evaluates whether the 12-LN quality measure and nodal ultra-staging impact DFS in patients not receiving adjuvant chemotherapy. Eligibility criteria include: a) biopsy-proven colon adenocarcinoma; b) absence of metastatic disease; c) > 12 LNs staged pathologically; d) pan-cytokeratin immunohistochemistry (IHC) of H&E-negative LNs; e) no adjuvant chemotherapy. RESULTS Of 442 patients screened, 203 patients were eligible. The majority of patients had intermediate grade (57.7%) and T3 tumors (64.9%). At a mean follow-up of 36.8±22.1 months (range 0–97 months), 94.3% remain disease-free. Recurrence was least likely in patients with ≥12, H&E negative, and IHC negative LNs (pN0i−): 2.6% vs.16.7% in the pN0i+ group (p<0.0001). CONCLUSIONS This is the first prospective report to demonstrate that patients with optimally staged node-negative colon cancer (≥12 LNs, pN0i−) are unlikely to benefit from adjuvant chemotherapy, as 97% remain disease free after primary tumor resection. Both surgical and pathological quality measures are imperative in the planning of clinical trials in non-metastatic colon cancer. PMID:26213360

Markers of preoperative tumor immunity, such as platelet-to-lymphocyte ratio (PLR), have been reported to be prognostic factors for patients with various cancers. However, the relationship between PLR and the prognosis of non-small cell lung cancer (NSCLC) patients treated with surgery and adjuvant chemotherapy as a multidisciplinary treatment is unknown. We enrolled 327 NSCLC patients treated surgically with or without adjuvant chemotherapy (78 and 249 patients, respectively) at our hospital from 2008 to 2012. Patients had no preoperative hematological disease or infection. Preoperative PLR and clinicopathologic characteristics were recorded and their potential associations and prognostic values were assessed by Kaplan-Meier and multivariate Cox regression. The optimal cut-off value for high and low PLR was calculated from receiver operating characteristic curves. The five-year overall survival rates for patients with low and high PLR were 78% and 57% (P < 0.01) for all patients, and 69% and 37% (P < 0.01) for patients who received adjuvant chemotherapy, respectively. Similarly, the five-year disease-free survival rates for patients with low and high PLR were 66% and 62% (P = 0.03) for all patients, and 47% and 14% (P < 0.01) for patients who received adjuvant chemotherapy, respectively. Cox proportional hazard regression indicated that high PLR was an independent prognostic factor for both overall and disease-free survival in the adjuvant chemotherapy group. Elevated PLR predicts poor prognosis in surgically treated NSCLC patients, especially those who receive adjuvant chemotherapy. © 2017 The Authors.

Breast cancer poses a huge medical burden to the U.S. health-care system, and chemotherapy is an important contributor to cancer costs. This article examines the differences between breast cancer patients who received chemotherapy and those who did not in costs and survival by age, treatment, and axillary node status. We studied a cohort of 23,110 node-positive and 31,572 node-negative women aged 65 years and older diagnosed with incident American Joint Committee on Cancer stage I, II, or IIIA breast cancer between January 1, 1991, and December 31, 2002, using Surveillance Epidemiology and End Results-Medicare data. Total treatment costs and costs associated with the use of chemotherapy were estimated by using the phase-of-care approach. The phase-specific costs were combined to estimate total Medicare payments for cancer care from diagnosis to death. Cox proportional hazard ratio of mortality was used to determine the effectiveness of adjuvant chemotherapy after adjusting for selected patient and tumor characteristics. We used propensity scores to minimize the bias associated with the receipt of adjuvant chemotherapy. Regression-adjusted difference in the average lifetime cost estimates for all node-positive patients receiving chemotherapy was approximately $2438 and was significantly higher (P < 0.05) than for patients not receiving chemotherapy. Mortality was significantly lower in node-positive and node-negative women aged 65 to 74 years receiving chemotherapy. Decision makers can use cost and effectiveness estimates from this study to assess the relative value of chemotherapy in different age groups.

Objective We hypothesized that metachronous colorectal liver metastases (CLM) have different biology after failure of oxaliplatin (FOLFOX) compared to 5-fluorouracil (5-FU) or no chemotherapy for adjuvant treatment of colorectal cancer (CRC). Background It is unclear whether patients treated with liver resection for metachronous CLM after adjuvant FOLFOX for CRC have worse outcomes than those who received 5-FU or no chemotherapy. Methods We identified 341 patients who underwent hepatectomy for metachronous CLM (disease-free interval ≥12 months, 1993–2010). Mass-spectroscopy genotyping for somatic gene mutations in CLM was performed in a subset of 129 patients. Results Adjuvant treatment for primary CRC was FOLFOX in 77 patients, 5-FU in 169 patients, and no chemotherapy in 95 patients. Node-positive primary was comparable between FOLFOX and 5-FU but lower in the no-chemotherapy group (P < 0.0001). Median metastasis size was smaller in the FOLFOX group (2.5 cm) than in the 5-FU (3.0 cm) or no-chemotherapy (3.5 cm) groups, (P = 0.008) although prehepatectomy chemotherapy utilization, metastases number, and carcinoembryonic antigen levels were similar. Disease-free survival (DFS) and overall survival (OS) rates after hepatectomy were worse in patients treated with adjuvant FOLFOX [DFS at 3 years: 14% vs 38% (5-FU) vs 45% (no-chemo), OS at 3 years: 58% vs 70% (5-FU) vs 84% (no-chemo)]. On multivariate analysis, adjuvant FOLFOX was associated with worse DFS (P < 0.0001) and OS (P < 0.0001). Mutation analysis revealed ≥1 mutations in 57% of patients (27/47) after FOLFOX, 29% (12/41) after 5-FU, and 32% (13/41) after no chemotherapy (P = 0.011). Conclusions Adjuvant FOLFOX for primary CRC is associated with a high rate of somatic mutations in liver metastases and inferior outcomes after hepatectomy for metachronous CLM. PMID:22968062

Glutathione S-transferase Pi expression predicts response to adjuvant chemotherapy for stage C colon cancer: a matched historical control study

PubMed Central

2012-01-01

Background This study examined the association between overall survival and Glutathione S-transferase Pi (GST Pi) expression and genetic polymorphism in stage C colon cancer patients after resection alone versus resection plus 5-fluourouracil-based adjuvant chemotherapy. Methods Patients were drawn from a hospital registry of colorectal cancer resections. Those receiving chemotherapy after it was introduced in 1992 were compared with an age and sex matched control group from the preceding period. GST Pi expression was assessed by immunohistochemistry. Overall survival was analysed by the Kaplan-Meier method and Cox regression. Results From an initial 104 patients treated with chemotherapy and 104 matched controls, 26 were excluded because of non-informative immunohistochemistry, leaving 95 in the treated group and 87 controls. Survival did not differ significantly among patients with low GST Pi who did or did not receive chemotherapy and those with high GST Pi who received chemotherapy (lowest pair-wise p = 0.11) whereas patients with high GST Pi who did not receive chemotherapy experienced markedly poorer survival than any of the other three groups (all pair-wise p <0.01). This result was unaffected by GST Pi genotype. Conclusion Stage C colon cancer patients with low GST Pi did not benefit from 5-fluourouracil-based adjuvant chemotherapy whereas those with high GST Pi did. PMID:22639861

This retrospective study attempts to establish if a correlation exists between osteoporosis and hematopoiesis before and after adjuvant chemotherapy in the context of non-metastatic breast cancer. Osteoporosis is interpreted both as a direct marker of osteoblastic decline and as an indirect marker of increased bone marrow adiposity within the hematopoietic microenvironment. Patients from the "Centre du Sein" at CHUV (Centre Hospitalier Universitaire Vaudois) undergoing adjuvant chemotherapy were included in this study. Evolution of blood counts was studied in correlation with the osteoporosis status. Toxicity of chemotherapy was coded according to published probability of febrile neutropenia. One hundred forty-three women were included: mean age 52.1 ± 12.5 years, mean BMI (body mass index) 24.4 ± 4.1. BMD (bone mineral density) scored osteoporotic in 32% and osteopenic in 45%. Prior to chemotherapy, BMD was positively correlated with neutrophil (p < 0.001) and thrombocyte (p = 0.01) count; TBS (trabecular bone score) was not correlated with blood count. After the first cycle of chemotherapy, an increase of one point in TBS correlated with a decrease of 57% on the time to reach leucocyte nadir (p = 0.004). There was a positive correlation between BMD and risk of infection (p < 0.001). Our data demonstrates an association between osteoporosis and lower blood counts in a younger cohort than previously published, extending it for the first time to neutrophil counts in females. Our results suggest that the healthier the bone, the earlier the lowest leucocyte count value, prompting further research on this area.

Background Decision-making for or against neoadjuvant or adjuvant chemotherapy in postmenopausal patients with hormone receptor-positive breast cancer does not follow any clear guidelines, and some patients may unnecessarily undergo chemotherapy and be exposed to the associated toxicity. The aim of this study was to identify the patient population for whom this issue may bear relevance. Methods Patients being treated with letrozole in the prospective multicenter noninterventional EvAluate-TM study were recruited. The percentage of patients receiving chemotherapy and factors associated with chemotherapy administration were identified. Results In all, 3,924 (37.4%) patients received chemotherapy before treatment with letrozole. Of these, 293 (20%) underwent neoadjuvant therapy. Younger age was predictive for both adjuvant and neoadjuvant therapy. Overall, decisions in favor of administering chemotherapy are more likely to be made in patients with a higher body mass index (BMI), and neoadjuvant chemotherapy is administered at a higher rate in women with a lower BMI. Concomitant medication influenced the overall decision-making regarding chemotherapy, irrespective of whether it was given on a neoadjuvant or adjuvant basis. Conclusion There is an ongoing debate as to whether all of the many patients who receive chemotherapy actually benefit from it. Neoadjuvant chemotherapy is frequently administered in this patient population, and this should encourage further research to resolve current clinical and research issues. PMID:27920623

Purpose: To compare concomitant and sequential adjuvant chemoradiotherapy regimens in node-positive, operable breast cancer patients. Methods and Materials: This was a randomized, French, multicenter, phase III trial enrolling 638 eligible women with prior breast surgery and positive axillary dissection. Patients in Arm A received 500 mg/m{sup 2} 5-fluorouracil, 12 mg/m{sup 2} mitoxantrone, and 500 mg/m{sup 2} cyclophosphamide, with concomitant radiotherapy (50 Gy {+-} 10-20-Gy boost). Patients in Arm B received 500 mg/m{sup 2} 5-fluorouracil, 60 mg/m{sup 2} epirubicin, and 500 mg/m{sup 2} cyclophosphamide, with subsequent radiotherapy. Chemotherapy was administered on Day 1 every 21 days for 4 cycles. Results: Medianmore » treatment durations were 64 and 126 days (Arms A and B, respectively), with no significant difference in overall or disease-free survival. Five-year locoregional relapse-free survival favored patients with conservative surgery (two thirds of the population), with less local and/or regional recurrence in Arm A than in Arm B (3% vs. 9%; p 0.01). Multivariate analysis in this subgroup showed a 2.8-fold increased risk of locoregional recurrence with sequential chemoradiotherapy, independent of other prognostic factors (p = 0.027). Febrile neutropenia and Grade 3-4 leukopenia were significantly more frequent in Arm A. Subclinical left ventricular ejection fraction events at 1 year were more frequent with concomitant radiotherapy (p = 0.02). Conclusions: Concomitant radiotherapy with adjuvant fluorouracil, mitoxantrone, and cyclophosphamide has significantly better locoregional control in node-positive breast cancer after conservative surgery and 50% shorter treatment, albeit with slightly more acute toxicity. With mitoxantrone no longer available for adjuvant breast cancer treatment, alternative concomitant chemoradiotherapy studies are needed.« less

Anagen effluvium with reversible scalp alopecia is a known side effect of chemotherapy. However, there are an increasing number of reports in the literature documenting permanent alopecia in patients treated with taxanes. We sought to describe the clinicopathologic features in breast cancer patients who underwent treatment with taxanes and adjuvant hormonal chemotherapy. We reviewed the clinical and histopathologic information of a cohort of 10 patients treated with taxanes and adjuvant hormonal chemotherapy. We have observed 3 types of clinical patterns of alopecia (types A, B, and C), and have validated the histopathologic features showing alopecia areata-like and female pattern hair loss. The study was based on a small sample size and retrospective retrieval of clinical information and histopathologic review of posttreatment slides. We hypothesize a clinicopathologic model of hair follicle cycle disruption in response to the chemoinflammatory and hormonal insults to the hair follicles resulting in permanent alopecia. Clinicopathologic correlation is paramount to the understanding of the morphobiologic pathways in chemotherapy-induced alopecia caused by taxanes and adjuvant hormonal treatment.

Aquaporin 1 (AQP1), which functions as a water transporter, is associated with cancer cell proliferation, invasion, metastasis and angiogenesis in numerous types of solid cancer, including colorectal cancer (CRC). The focus of the present study was to address the potential clinical use of AQP1 expression in CRC as a prognostic and predictive biomarker for disease recurrence and therapeutic outcomes. The current study investigated the expression of AQP1 in surgically resected specimens from 268 patients with stage 0-IV CRC. AQP1 expression was positive in 112 (41.8%) patients, and was significantly associated with left-sided tumors (P<0.01) and with aggressive tumor phenotypes, including depth of invasion (P=0.03), lymph node metastasis (P=0.03), lymphatic invasion (P<0.01) and venous invasion (P<0.01). However, AQP1 expression had no significant prognostic effect on disease-free survival (DFS) in patients with stage II and III CRC following curative surgery. In 84 stage II and III patients who were administered 5-fluorouracil-based adjuvant chemotherapy, positive AQP1 expression was associated with an increased DFS rate compared with that of AQP1-negative patients (P=0.05). Additionally, these results identified that receiving adjuvant chemotherapy was not beneficial to patients with AQP1-negative tumors. This suggests that the expression of AQP1 may be a candidate biomarker predictive of response to 5-fluorouracil-based adjuvant chemotherapy following surgery in patients with stage II and III CRC.

Purpose To investigate the impact of modern postoperative radiotherapy (PORT) on overall survival (OS) for patients with N2 non–small-cell lung cancer (NSCLC) treated nationally with surgery and adjuvant chemotherapy. Patients and Methods Patients with pathologic N2 NSCLC who underwent complete resection and adjuvant chemotherapy from 2006 to 2010 were identified from the National Cancer Data Base and stratified by use of PORT (≥ 45 Gy). A total of 4,483 patients were identified (PORT, n = 1,850; no PORT, n = 2,633). The impact of patient and treatment variables on OS was explored using Cox regression. Results Median follow-up time was 22 months. On univariable analysis, improved OS correlated with younger age, treatment at an academic facility, female sex, urban population, higher income, lower Charlson comorbidity score, smaller tumor size, multiagent chemotherapy, resection with at least a lobectomy, and PORT. On multivariable analysis, improved OS remained independently predicted by younger age, female sex, urban population, lower Charlson score, smaller tumor size, multiagent chemotherapy, resection with at least a lobectomy, and PORT (hazard ratio, 0.886; 95% CI, 0.798 to 0.988). Use of PORT was associated with an increase in median and 5-year OS compared with no PORT (median OS, 45.2 v 40.7 months, respectively; 5-year OS, 39.3% [95% CI, 35.4% to 43.5%] v 34.8% [95% CI, 31.6% to 38.3%], respectively; P = .014). Conclusion For patients with N2 NSCLC after complete resection and adjuvant chemotherapy, modern PORT seems to confer an additional OS advantage beyond that achieved with adjuvant chemotherapy alone.

Background There is currently no consensus regarding the optimal number of chemotherapy cycles to be administered before and after interval debulking surgery (IDS) in patients with advanced ovarian cancer. This study aimed to evaluate the impact of the number of neoadjuvant chemotherapy (NAC) and postoperative adjuvant chemotherapy (POAC) cycles on the survival of patients with advanced ovarian cancer undergoing NAC/IDS/POAC. Methods We retrospectively reviewed data from 203 patients who underwent NAC/IDS/POAC at Yonsei Cancer Hospital between 2006 and 2016. All patients underwent taxane plus carboplatin chemotherapy for NAC and POAC. The patient outcomes were analyzed according to the number of NAC, POAC, and total chemotherapy (NAC+POAC) cycles. Results Patients who received fewer than 6 cycles of total chemotherapy (n = 8) had poorer progression-free survival (PFS) and overall survival (OS) than those completing at least 6 cycles (p = 0.005 and p<0.001, respectively). Among patients who completed at least 6 cycles of total chemotherapy (n = 189), Kaplan-Meier analysis revealed no significant difference in either PFS or OS according to the number of NAC cycles (1–3 vs. ≥4; p = 0.136 and p = 0.267, respectively). Among patients who experienced complete remission after 3 cycles of POAC (n = 98), the addition of further POAC cycles did not improve the PFS or OS (3 vs. ≥4; p = 0.641 and p = 0.104, respectively). Conclusion IDS after 4 cycles of NAC may be a safe and effective option when completing 6 cycles of total chemotherapy. Furthermore, the addition of more than 3 cycles of POAC does not appear to influence the survival of patients achieving completion remission after 3 cycles of POAC. PMID:28873393

Colorectal cancer (CRC) diagnosis and treatment can have substantial detrimental impacts on health related quality of life (HRQOL) and physical function. This is especially true for older CRC patients and is of paramount concern in chemotherapy treatment decision making; yet, few studies to date have focused on understanding and managing fatigue in older CRC patients. We present the design of a study to evaluate the feasibility and impact of a home-based, self-directed physical activity intervention on fatigue in older CRC patients receiving adjuvant chemotherapy treatment. Secondary aims pertain to intervention impact on HRQOL, physical function, and self-efficacy for managing fatigue. Multi-site, randomized controlled trial of physical activity intervention compared to usual care in a sample of older adults undergoing adjuvant chemotherapy for CRC. Forty CRC patients will be recruited and study questionnaires/assessments will be performed at baseline, 3 months, and after completion of adjuvant chemotherapy. The primary outcome is a comparison of the change in fatigue from baseline to 3 months between Intervention and Control arms. We will also compare changes in engagement in physical activity, HRQOL, physical function, and self-efficacy. Exploratory analyses will compare Intervention and Control arms with regard to changes in muscle mass and a biomarker aging that is known to increase during chemotherapy (p16(INK4a)). If positive, findings from this pilot study would suggest the potential for improving the care of older persons with CRC undergoing adjuvant chemotherapy through a home-based physical activity intervention to manage fatigue, HRQOL, and physical function.

Purpose US veterans have been shown to be a vulnerable population with high cancer rates, and cancer care quality in Veterans Affairs (VA) hospitals is the focus of a congressionally mandated review. We examined rates of surgery and chemotherapy use among veterans with colon cancer at VA and non-VA facilities in California to gain insight into factors associated with quality of cancer care. Methods A retrospective cohort of incident colon cancer patients from the California Cancer Registry, who were ≥ 66 years old and eligible to use VA and Medicare between 1999 and 2001, were observed for 6 months after diagnosis. Results Among 601 veterans with colon cancer, 72% were initially diagnosed and treated in non-VA facilities. Among veterans with stage I to III cancer, those diagnosed and initially treated in VA facilities experienced similar colectomy rates as those at non-VA facilities. Stage III patients diagnosed and initially treated in VA versus non-VA facilities had similar odds of receiving adjuvant chemotherapy. In both settings, older patients had lower odds of receiving chemotherapy than their younger counterparts even when race and comorbidity were considered (age 76 to 85 years: odds ratio [OR] = 0.18; 95% CI, 0.07 to 0.46; age ≥ 86 years: OR = 0.17; 95% CI, 0.04 to 0.73). Conclusion In California, older veterans with colon cancer used both VA and non-VA facilities for cancer treatment, and odds of receiving cancer-directed surgery and chemotherapy were similar in both systems. Among stage III patients, older age lowered odds of receiving adjuvant chemotherapy in both systems. Further studies should continue to explore potential health system effects on quality of colon cancer care across the United States. PMID:20406940

Introduction. Preoperative chemotherapy (PC) for operable breast cancer has shown significant benefits in prospective trials. Many patients are treated in the community setting and some may question the applicability of PC outside the university setting. Methods. Retrospective review was performed of stage II and IIIA breast cancer patients treated from January 2002 to July 2009. Fifty-three of 57 patients who underwent PC were matched based on age, tumor size, and hormone receptor status with 53 patients who did not undergo PC. Differences in patient compliance with physician recommendations for all types of adjuvant therapy were evaluated. Crude odds ratios and adjusted odds ratios derived from conditional logistic regression models were calculated. Results. There were 106 patients included. Patient compliance with chemotherapy was better in the PC group than in the adjuvant chemotherapy (AC) group (100% versus 70%; p = .0001). Similarly, more patients in the PC group completed radiation therapy (96% versus 65%; p = .0003) and initiated hormonal therapy (100% versus 62%; p = .0001). Conditional logistic regression revealed that higher pathologic stage and current cigarette smoking were associated with poorer compliance with chemotherapy. For radiation therapy, the univariate model revealed that compliance with chemotherapy and being employed were associated with completion of radiation, whereas current cigarette smoking and larger pathologic size were associated with poorer compliance with radiation. For hormonal therapy, current cigarette smokers were more likely to be noncompliant with initiation of hormonal therapy. Conclusions. PC for operable breast cancer can improve patient compliance with chemotherapy. Current cigarette smokers were more likely to be noncompliant with all types of adjuvant therapy. PMID:21558134

Purpose Risk of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) post-breast cancer treatment with adjuvant chemotherapy and granulocyte colony-stimulating factors (G-CSF) is not fully characterized. Our objective was to estimate MDS/AML risk associated with specific breast cancer treatments. Methods We conducted a retrospective cohort study of women ages ≥66 years with stage I-III breast cancer between 2001 and 2009 using the Surveillance, Epidemiology and End Results-Medicare database. Women were classified as receiving treatment with radiation, chemotherapy and/or G-CSF. We used multivariable Cox proportional hazards models to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for MDS/AML risk. Results Among 56,251 breast cancer cases, 1.2% developed MDS/AML during median follow-up of 3.2 years. 47.1% of women received radiation and 14.3% received chemotherapy. Compared to breast cancer cases treated with surgery alone, those treated with chemotherapy (HR=1.38, 95%-CI: 0.98–1.93) and chemotherapy/radiation (HR=1.77, 95%-CI: 1.25–2.51) had increased risk of MDS/AML; but not radiation alone (HR=1.08, 95% CI: 0.86–1.36). Among chemotherapy regimens and G-CSF, MDS/AML risk was differentially associated with anthracycline/cyclophosphamide-containing regimens (HR=1.86, 95%-CI: 1.33–2.61) and filgrastim (HR=1.47, 95%-CI: 1.05–2.06), but not pegfilgrastim (HR=1.10, 95%-CI: 0.73–1.66). Conclusions We observed increased MDS/AML risk among older breast cancer survivors treated with anthracycline/cyclophosphamide chemotherapy that was enhanced by G-CSF. Although small, this risk warrants consideration when determining adjuvant chemotherapy and neutropenia prophylaxis for breast cancer patients. PMID:26450505

This study aimed to examine how biomarker information would impact patients' preferences and physicians' recommendations for adjuvant breast cancer therapy. At the 18-month follow-up, participants in a large, double-blind randomized controlled trial of adjuvant chemotherapy with bevacizumab or placebo (E5103) were surveyed about their preferred treatment (either chemotherapy A alone or chemotherapy A+B) in two hypothetical scenarios: (1) without biomarker information; and (2) after learning that they tested positive for a "B-receptor" which modestly increased both the benefit and toxicity expected with chemotherapy A+B. We performed a cross-sectional analysis of the prospectively collected survey data and used the McNemar's test to examine changes in treatment preferences. A one-time survey of clinical investigators who enrolled patients on the trial evaluated physician recommendations in response to the same biomarker information. 439 patients completed both scenarios on 18-month survey. Most participants preferred A+B in both scenario 1 and 2 (77 and 76% respectively). The increase in benefit and toxicity associated with the positive biomarker information in scenario 2 led 60/439 (14%) of patients to switch their treatment preference. The corresponding physician survey revealed that most physicians chose regimen A+B in scenario 1 (77%), and moreso after the biomarker information was available in scenario 2 (84%). Information about a positive biomarker indicating increased benefit and toxicity from additional chemotherapy did not change many participants' preferred treatment. The majority preferred the most effective course in both scenarios. Similarly, most investigators discounted increased toxicity and valued increased benefit. Parent Trial Registration: NCT00433511.

2013-01-01

Background High-quality care must be not only appropriate but also timely. We assessed time to initiation of adjuvant chemotherapy for breast cancer as well as factors associated with delay to help identify targets for future efforts to reduce unnecessary delays. Methods Using data from the National Comprehensive Cancer Network (NCCN) Outcomes Database, we assessed the time from pathological diagnosis to initiation of chemotherapy (TTC) among 6622 women with stage I to stage III breast cancer diagnosed from 2003 through 2009 and treated with adjuvant chemotherapy in nine NCCN centers. Multivariable models were constructed to examine factors associated with TTC. All statistical tests were two-sided. Results Mean TTC was 12.0 weeks overall and increased over the study period. A number of factors were associated with a longer TTC. The largest effects were associated with therapeutic factors, including immediate postmastectomy reconstruction (2.7 weeks; P < .001), re-excision (2.1 weeks; P < .001), and use of the 21-gene reverse-transcription polymerase chain reaction assay (2.2 weeks; P < .001). In comparison with white women, a longer TTC was observed among black (1.5 weeks; P < .001) and Hispanic (0.8 weeks; P < .001) women. For black women, the observed disparity was greater among women who transferred their care to the NCCN center after diagnosis (P interaction = .008) and among women with Medicare vs commercial insurance (P interaction < .001). Conclusions Most observed variation in TTC was related to use of appropriate therapeutic interventions. This suggests the importance of targeted efforts to minimize potentially preventable causes of delay, including inefficient transfers in care or prolonged appointment wait times. PMID:23264681

First-line postoperative adjuvant chemotherapies with S-1 and capecitabine and oxaliplatin (XELOX) were first recommended for resectable gastric cancer patients in the 2010 and 2011 Chinese NCCN Clinical Practice Guidelines in Oncology: Gastric Cancer; however, their economic impact in China is unknown. The aim of this study was to compare the cost-effectiveness of adjuvant chemotherapy with XELOX, with S-1 and no treatment after a gastrectomy with extended (D2) lymph-node dissection among patients with stage II-IIIB gastric cancer. A Markov model, based on data from two clinical phase III trials, was developed to analyse the cost-effectiveness of patients in the XELOX group, S-1 group and surgery only (SO) group. The costs were estimated from the perspective of Chinese healthcare system. The utilities were assumed on the basis of previously published reports. Costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICER) were calculated with a lifetime horizon. One-way and probabilistic sensitivity analyses were performed. For the base case, XELOX had the lowest total cost ($44,568) and cost-effectiveness ratio ($7,360/QALY). The relative scenario analyses showed that SO was dominated by XELOX and the ICERs of S-1 was $58,843/QALY compared with XELOX. The one-way sensitivity analysis showed that the most influential parameter was the utility of disease-free survival. The probabilistic sensitivity analysis predicted a 75.8% likelihood that the ICER for XELOX would be less than $13,527 compared with S-1. When ICER was more than $38,000, the likelihood of cost-effectiveness achieved by S-1 group was greater than 50%. Our results suggest that for patients in China with resectable disease, first-line adjuvant chemotherapy with XELOX after a D2 gastrectomy is a best option comparing with S-1 and SO in view of our current study. In addition, S-1 might be a better choice, especially with a higher value of willingness-to-pay threshold.

The CpG island methylator phenotype may confer a survival benefit in patients with stage II or III colorectal carcinomas receiving fluoropyrimidine-based adjuvant chemotherapy

PubMed Central

2011-01-01

Background Colorectal carcinoma (CRC) with CpG island methylator phenotype (CIMP) is recognized as a distinct subgroup of CRC, and CIMP status affects prognosis and response to chemotherapy. Identification of CIMP status in CRC is important for proper patient management. In Eastern countries, however, the clinicopathologic and molecular characteristics and prognosis of CRCs with CIMP are still unclear. Methods A total of 245 patients who underwent their first surgical resection for sporadic CRC were enrolled and CIMP status of the CRCs was determined using the quantitative MethyLight assay. The clinicopathologic and molecular characteristics were reviewed and compared according to CIMP status. In addition, the three-year recurrence-free survival (RFS) of 124 patients with stage II or stage III CRC was analyzed in order to assess the effectiveness of fluoropyrimidine-based adjuvant chemotherapy with respect to CIMP status. Results CIMP-high CRCs were identified in 34 cases (13.9%), and were significantly associated with proximal tumor location, poorly differentiated carcinoma, mucinous histology, and high frequencies of BRAF mutation, MGMT methylation, and MSI-high compared to CIMP-low/negative carcinomas. For patients with stage II or III CIMP-low/negative CRCs, no significant difference was found in RFS between those undergoing surgery alone and those receiving surgery with fluoropyrimidine-based adjuvant chemotherapy. However, for patients with CIMP-high CRCs, patients undergoing surgery with fluoropyrimidine-based adjuvant chemotherapy (n = 17; three-year RFS: 100%) showed significantly better RFS than patients treated with surgery alone (n = 7; three-year RFS: 71.4%) (P = 0.022). Conclusions Our results suggest that selected patients with CIMP-high CRC may benefit from fluoropyrimidine-based adjuvant chemotherapy with longer RFS. Further large scale-studies are required to confirm our results. PMID:21827707

As a new subtype of breast cancer, molecular apocrine breast cancer (MABC) is estrogen receptor (ER) and progesterone receptor (PR) negative expression, but androgen receptor (AR) positive expression. The prognostic significance and clinical biological behavior of MABC have remained unclear up to now. This study aimed to analysis the distant metastasis behavior and response to adjuvant radiotherapy and chemotherapy of MABC subgroup. The report showed that there were significant differences between early and late distant metastasizing tumors with respect to Ki67, epidermal growth factor receptor 2 (HER2) and vascular endothelial growth factor (VEGF) expressions by a retrospective analysis consisting of 410 invasive breast cancer patients, which included 205 MABC and 205 nonMABC cases. MABC subgroup metastasized earlier than nonMABC subgroup, and MABC showed a tendency for a higher metastasis rate in lung, liver and brain, but lower in bone. HER2-positive or VEGF-positive tumors were more inclined to develop bone metastasis within MABC subgroup. The survival rate was superior for patients undergone both adjuvant radiotherapy and chemotherapy than those undergone chemotherapy alone in nonMABC subgroup, but there was no significant difference in MABC subgroup. Our data suggested that MABC subgroup seemed to develop distant metastasis earlier than nonMABC subgroup, and patients with MABC indicated poor prognosis. This study might also provide a foundation for helping patients receive reasonable treatments according to molecular subtype. PMID:27340922

Background The addition of oxaliplatin to adjuvant 5-fluorouracil (5-FU) improves survival of patients with stage III colon cancer in randomized clinical trials (RCTs). However, RCT participants are younger, healthier, and less racially diverse than the general cancer population. Thus, the benefit of oxaliplatin outside RCTs is uncertain. Subjects and Methods Patients younger than 75 years with stage III colon cancer who received chemotherapy within 120 days of surgical resection were identified from five observational data sources—the Surveillance, Epidemiology, and End Results registry linked to Medicare claims (SEER–Medicare), the New York State Cancer Registry (NYSCR) linked to Medicaid and Medicare claims, the National Comprehensive Cancer Network (NCCN) Outcomes Database, and the Cancer Care Outcomes Research & Surveillance Consortium (CanCORS). Overall survival (OS) was compared among patients treated with oxaliplatin vs non–oxaliplatin-containing adjuvant chemotherapy. Overall survival for 4060 patients diagnosed during 2004–2009 was compared with pooled data from five RCTs (the Adjuvant Colon Cancer ENdpoinTs [ACCENT] group, n = 8292). Datasets were juxtaposed but not combined using Kaplan–Meier curves. Covariate and propensity score adjusted proportional hazards models were used to calculate adjusted survival hazard ratios (HR). Stratified analyses examined effect modifiers. All statistical tests were two-sided. Results The survival advantage associated with the addition of oxaliplatin to adjuvant 5-FU was evident across diverse practice settings (3-year OS: RCTs, 86% [n = 1273]; SEER–Medicare, 80% [n = 1152]; CanCORS, 88% [n = 129]; NYSCR–Medicaid, 82% [n = 54]; NYSCR–Medicare, 79% [n = 180]; and NCCN, 86% [n = 438]). A statistically significant improvement in 3-year overall survival was seen in the largest cohort, SEER–Medicare, and in the NYSCR–Medicare cohort (non–oxaliplatin-containing vs oxaliplatin-containing adjuvant therapy

We conducted a prospective clinical study to individualize adjuvant chemotherapy after complete resection of non-small-cell lung cancer (NSCLC), based on the drug sensitivity test. Patients with resectable c-stage IB-IIIA NSCLC were registered between 2005 and 2010. We performed the collagen gel droplet-embedded culture drug sensitivity test (CD-DST) on a fresh surgical specimen to assess in vitro chemosensitivity and evaluated the prognostic outcome after adjuvant chemotherapy with carboplatin/paclitaxel based on the CD-DST. Among 92 registered patients, 87 were eligible for inclusion in the analysis. The success rate of CD-DST was 86% and chemosensitivity to carboplatin and/or paclitaxel was evident in 57 (76%) of the 75 patients. Adjuvant chemotherapy was completed in 22 (73%) of 30 patients. The 5-year overall survival rates were 71, 73, and 75% for all, CD-DST success, and chemosensitive patients, respectively. The 5-year disease-free survival and overall survival rates of the chemosensitive patients who completed adjuvant chemotherapy using carboplatin/paclitaxel were 68 and 82%, respectively. The 5-year disease-free survival and overall survival rates of the patients with stage II-IIIA chemosensitive NSCLC were 58 and 75%, respectively. Comparative analyses of the chemosensitive and non-chemosensitive/CD-DST failure groups showed no significant survival difference. CD-DST can be used to evaluate chemosensitivity after lung cancer surgery; however, its clinical efficacy for assessing individualized treatment remains uncertain.

To establish whether women over 65 years of age with newly diagnosed with breast cancer (BC) receive adjuvant chemotherapy less frequently than younger postmenopausal women and whether comorbidity influences this potential undertreatment. In a single-site, retrospective, comparative study, postmenopausal early stage BC patients treated between 01/2001 and 12/2005 at a major German university hospital were analyzed in two age Groups A and B (≥65 vs. <65 years) for initiation and completion of guideline-recommended adjuvant chemotherapy. Risk stratification was based on the 2005 St. Gallen Consensus Conference criteria. Comorbidity was parametrized using the Charlson Comorbidity Index (CCI). Analysis included 634 patients, 380 in Group A and 254 in Group B. Mean age (range) was 73 (65-94) and 61 (55-64) years, respectively. The proportion of patients from Group A given ≥3 cycles of chemotherapy was significantly decreased as compared to Group B. 52 % of patients with CCI <3 but only 20 % with CCI ≥3 were recommended to undergo chemotherapy (p < 0.001). Median follow-up [95 % confidence interval (CI)] was 85 (82-88) months. DFS was significantly shorter in patients aged ≥65 years as compared to younger postmenopausal patients (HR, 0.598; 95 % CI, 0.358-0.963; p = 0.048). Despite being high-risk patients, older women with early stage BC were often not given guideline-recommended chemotherapy. Higher recurrence rates compared with younger postmenopausal women suggest that older patients are undertreated. Treatment needs to be adapted to general health and tumor biology rather than age. More trials in elderly BC patients are needed.

Uncertainty exists regarding appropriate and affordable use of adjuvant chemotherapy in stage II colon cancer (T3, proficient DNA mismatch repair). This study aimed to estimate the effectiveness and costs from a US societal perspective of a multigene recurrence score (RS) assay for patients recently diagnosed with stage II colon cancer (T3, proficient DNA mismatch repair) eligible for adjuvant chemotherapy. RS was compared with guideline-recommended clinicopathological factors (tumor stage, lymph nodes examined, tumor grade, and lymphovascular invasion) by using a state-transition (Markov) lifetime model. Data were obtained from published literature, a randomized controlled trial (QUick And Simple And Reliable) of adjuvant chemotherapy, and rates of chemotherapy use from the National Cooperative Cancer Network Colon/Rectum Cancer Outcomes study. Life-years, quality-adjusted life expectancy, and lifetime costs were examined. The RS is projected to reduce adjuvant chemotherapy use by 17% compared with current treatment patterns and to increase quality-adjusted life expectancy by an average of 0.035 years. Direct medical costs are expected to decrease by an average of $2971 per patient. The assay was cost saving for all subgroups of patients stratified by clinicopathologic factors. The most influential variables affecting treatment decisions were projected years of life remaining, recurrence score, and patients' disutilities associated with adjuvant chemotherapy. Use of the multigene RS to assess recurrence risk after surgery in stage II colon cancer (T3, proficient DNA mismatch repair) may reduce the use of adjuvant chemotherapy without decreasing quality-adjusted life expectancy and be cost saving from a societal perspective. These findings need to be validated in additional cohorts, including studies of clinical practice as assay use diffuses into nonacademic settings.

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

Case 1 : A 48-year-old man presenting with gross hematuria was suspected to have a tumor located in the bladder dome. He was referred to our department for further examination and treatment. Cystoscopy showed a dome-shaped mass in the supravesical region. Computed tomography and magnetic resonance imaging indicated the possibility of urachal carcinoma and peritoneal dissemination. Therefore, partial cystectomy with urachal resection was performed. The intraoperative findings were disseminated peritoneal nodules and mucus entering the peritoneal cavity from the tumor. On pathological examination, the tumor was classified as a mucinous-type adenocarcinoma, and 6 courses of TS-1/cisplatin (CDDP) therapy were administered to the patient as adjuvant chemotherapy. To date (10 months since the surgery), there has been no disease progression. Case 2 : A 76-year-old woman was referred to our department with a finding of a tumor in the bladder dome during her detailed examination for lung tumors. Cystoscopy showed nodular tumors, indicating lung metastases of the urachal carcinoma. Therefore, partial cystectomy with urachal resection was performed. On pathological examination, the tumor was classified as an enteric-type adenocarcinoma, and 2 courses of TS-1/CDDP therapy were administered to the patient as adjuvant chemotherapy. However, due to the development of marked bone marrow depression, the drugs had to be discontinued. Nonetheless, the lung metastases markedly diminished in size. To date (9 months since the discontinuation of chemotherapy), there has been no disease progression.

The Oncotype DX® Recurrence Score® (RS) is a validated genomic predictor of outcome and response to adjuvant chemotherapy in ER-positive breast cancer. Adjuvant! was developed using SEER registry data and results from the Early Breast Cancer Clinical Trialists’ overview analyses to estimate outcome and benefit from adjuvant hormonal therapy and chemotherapy. In this report we compare the prognostic and predictive utility of these two tools in node-negative, ER-positive breast cancer. RS and Adjuvant! results were available from 668 tamoxifen-treated NSABP B-14 patients: 227 tamoxifen-treated NSABP B-20 patients, and 424 chemotherapy-plus-tamoxifen-treated B-20 patients. Adjuvant! results were also available from 1952 B-20 patients. The primary endpoint was distant recurrence-free interval (DRFI). Cox proportional hazards models were used to compare the prognostic and predictive utility of RS and Adjuvant!. Both RS (p<0.001) and Adjuvant! (p=0.002) provided strong independent prognostic information in tamoxifen-treated patients. Combining RS and individual clinicopathologic characteristics provided greater prognostic discrimination than combining RS and the composite Adjuvant!. In the B-20 cohort with RS results (n=651), RS was significantly predictive of chemotherapy benefit (interaction p=0.031 for DRFI, p=0.011 for overall survival [OS], p=0.082 for disease-free survival [DFS]), but Adjuvant! was not (interaction p=0.99, p=0.311 and p=0.357, respectively). However, in the larger B-20 sub-cohort (n=1952), Adjuvant! was significantly predictive of chemotherapy benefit for OS (interaction p=0.009) but not for DRFI (p=0.219) or DFS (p=0.099). Prognostic estimates can be optimized by combining RS and clinicopathologic information instead of simply combining RS and Adjuvant!. RS should be used for estimating relative chemotherapy benefit.

Decision-making for or against neoadjuvant or adjuvant chemotherapy in postmenopausal patients with hormone receptor-positive breast cancer does not follow any clear guidelines, and some patients may unnecessarily undergo chemotherapy and be exposed to the associated toxicity. The aim of this study was to identify the patient population for whom this issue may bear relevance. Patients being treated with letrozole in the prospective multicenter noninterventional EvAluate-TM study were recruited. The percentage of patients receiving chemotherapy and factors associated with chemotherapy administration were identified. In all, 3,924 (37.4%) patients received chemotherapy before treatment with letrozole. Of these, 293 (20%) underwent neoadjuvant therapy. Younger age was predictive for both adjuvant and neoadjuvant therapy. Overall, decisions in favor of administering chemotherapy are more likely to be made in patients with a higher body mass index (BMI), and neoadjuvant chemotherapy is administered at a higher rate in women with a lower BMI. Concomitant medication influenced the overall decision-making regarding chemotherapy, irrespective of whether it was given on a neoadjuvant or adjuvant basis. There is an ongoing debate as to whether all of the many patients who receive chemotherapy actually benefit from it. Neoadjuvant chemotherapy is frequently administered in this patient population, and this should encourage further research to resolve current clinical and research issues.

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

PubMed

Serke, Monika

2010-01-01

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

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

Proteomics allows for better understanding of the function and regulation of cancer cells mediated by intra- and extracellular signaling networks. Integrating such information with clinicopathological characteristics of the tumor may lead to either detection of disease biomarkers useful to differentiate high-from low-risk patients, or to identification of new drug targets. Adjuvant chemotherapy is currently a personalized treatment strategy, especially for breast cancer (BC) patients, and the risk assessment of each patient influences its use because the benefit strictly correlates with the level of risk. Luminal A BCs are endocrine therapy (ET)-sensitive but exhibit low sensitivity to chemotherapy, while luminal B cancers, according to the Ki-67 proliferation rate may require for chemotherapy in addition to ET, and HER2-positive tumors derive benefit from adjuvant chemotherapy containing an anthracycline, a taxane and trastuzumab for one year. Triple-negative BCs have a high degree of genomic instability exhibiting a more aggressive clinical course with respect to other types of BC, and the anthracycline-taxane regimen constitutes the standard approach. Studies considering the use of targeted approaches (drugs), including poly (ADP-ribose) polymerase (PARP-1), vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR) inhibitors, or EFGR and HER2 blockers, are still under evaluation. In the genomic era, promising new targeted-therapies are worthy of further investigation, and mTOR inhibitors have been used for patients with high-risk ER-positive and HER2-negative tumors. In the near future, genetic and molecular profiling of BC will help to better-categorize patients, determine the choice of chemotherapy in low-risk, or intensify the treatment in high-risk cancer patients, eventually revealing new targeted agents.

The discussion on the role of adjuvant chemotherapy for rectal cancer patients treated according to current guidelines is still ongoing. A multicentre, randomized phase III trial, PROCTOR-SCRIPT, was conducted to compare adjuvant chemotherapy with observation for rectal cancer patients treated with preoperative (chemo)radiotherapy and total mesorectal excision (TME). The PROCTOR-SCRIPT trial recruited patients from 52 hospitals. Patients with histologically proven stage II or III rectal adenocarcinoma were randomly assigned (1:1) to observation or adjuvant chemotherapy after preoperative (chemo)radiotherapy and TME. Radiotherapy consisted of 5 × 5 Gy. Chemoradiotherapy consisted of 25 × 1.8-2 Gy combined with 5-FU-based chemotherapy. Adjuvant chemotherapy consisted of 5-FU/LV (PROCTOR) or eight courses capecitabine (SCRIPT). Randomization was based on permuted blocks of six, stratified according to centre, residual tumour, time between last irradiation and surgery, and preoperative treatment. The primary end point was overall survival. Of 470 enrolled patients, 437 were eligible. The trial closed prematurely because of slow patient accrual. Patients were randomly assigned to observation (n = 221) or adjuvant chemotherapy (n = 216). After a median follow-up of 5.0 years, 5-year overall survival was 79.2% in the observation group and 80.4% in the chemotherapy group [hazard ratio (HR) 0.93, 95% confidence interval (CI) 0.62-1.39; P = 0.73]. The HR for disease-free survival was 0.80 (95% CI 0.60-1.07; P = 0.13). Five-year cumulative incidence for locoregional recurrences was 7.8% in both groups. Five-year cumulative incidence for distant recurrences was 38.5% and 34.7%, respectively (P = 0.39). The PROCTOR-SCRIPT trial could not demonstrate a significant benefit of adjuvant chemotherapy with fluoropyrimidine monotherapy after preoperative (chemo)radiotherapy and TME on overall survival, disease-free survival, and recurrence rate. However, this trial did not complete

There is currently no consensus regarding the optimal number of chemotherapy cycles to be administered before and after interval debulking surgery (IDS) in patients with advanced ovarian cancer. This study aimed to evaluate the impact of the number of neoadjuvant chemotherapy (NAC) and postoperative adjuvant chemotherapy (POAC) cycles on the survival of patients with advanced ovarian cancer undergoing NAC/IDS/POAC. We retrospectively reviewed data from 203 patients who underwent NAC/IDS/POAC at Yonsei Cancer Hospital between 2006 and 2016. All patients underwent taxane plus carboplatin chemotherapy for NAC and POAC. The patient outcomes were analyzed according to the number of NAC, POAC, and total chemotherapy (NAC+POAC) cycles. Patients who received fewer than 6 cycles of total chemotherapy (n = 8) had poorer progression-free survival (PFS) and overall survival (OS) than those completing at least 6 cycles (p = 0.005 and p<0.001, respectively). Among patients who completed at least 6 cycles of total chemotherapy (n = 189), Kaplan-Meier analysis revealed no significant difference in either PFS or OS according to the number of NAC cycles (1-3 vs. ≥4; p = 0.136 and p = 0.267, respectively). Among patients who experienced complete remission after 3 cycles of POAC (n = 98), the addition of further POAC cycles did not improve the PFS or OS (3 vs. ≥4; p = 0.641 and p = 0.104, respectively). IDS after 4 cycles of NAC may be a safe and effective option when completing 6 cycles of total chemotherapy. Furthermore, the addition of more than 3 cycles of POAC does not appear to influence the survival of patients achieving completion remission after 3 cycles of POAC.

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

The extent to which medical oncologists consider non-clinical patient factors when deciding to recommend adjuvant chemotherapy is unknown. Medical oncologists who treated a population-based sample of early stage breast cancer patients reported to the Los Angeles and Detroit Surveillance, Epidemiology, and End Results registries 2005-2007 were asked how strongly they consider a patient's ability to follow instructions, level of social support, and level of work support/flexibility in decisions to recommend adjuvant chemotherapy. Responses of 4 (Quite strongly) or 5 (Very strongly) on a five-point Likert scale defined strong consideration. Associations between oncologist/practice characteristics and strong consideration of each non-clinical factor were examined. 134 oncologists (66 %) reported strong consideration of one or more factor. Ability to follow instructions was strongly considered by 120 oncologists (59 %), social support by 78 (38 %), and work support/flexibility by 73 (36 %). Larger percent of practice devoted to breast cancer was associated with lower likelihood of strongly considering ability to follow instructions [odds ratio (OR) 0.98, 95 % confidence interval (CI) 0.97-0.99; P = 0.04]. Increased years in practice was associated with lower likelihood of strongly considering social support (OR 0.96, CI 0.93-0.99; P = 0.011), while non-white race (OR 2.1, CI 1.03-4.26; P = 0.041) and tumor board access (OR 2.04, CI 1.01-4.12; P = 0.048) were associated with higher likelihood. Non-white race was associated with strongly considering work support/flexibility (OR 2.44, CI 1.21-4.92; P = 0.013). Tumor board access (OR 2, CI 1.00-4.02; P = 0.051) was borderline significant. Non-clinical patient factors play a role in medical oncologist decision-making for breast cancer adjuvant chemotherapy recommendations.

Weight gain is observed in breast cancer patients receiving chemotherapy and is a well-known complication. Several factors that contributing to weight gain have been identified. However, there is a lack of information about factors associated with weight changes following adjuvant chemotherapy. A retrospective cohort of 200 pre- and post-menopausal Mexican patients treated for breast cancer was made. Anthropometric variables were measured before/after treatment. Biomarkers, cellular differentiation and chemotherapy were similar between groups. Weight gain occurred in 85.6% of pre-menopausal and 72.6% of post-menopausal women (p = .03). At the end of chemotherapy, weight and body mass index (BMI) did not differ significantly between pre-menopausal (69.3 ± 12.6 kg; 26.6 ± 4.8 kg/m 2 ) and post-menopausal women (69.5 ± 10.9 kg; 27.3 ± 4.4 kg/m 2 ) (p = .91 and 0.34). Dexamethasone doses were higher in pre-menopausal (85.7 ± 39.1 g) than post-menopausal patients (79.2 ± 22.5 g; p = .13). Weight loss was observed in 9.2% of pre-menopausal and 20.2% of post-menopausal patients (p = .04). A multivariate analysis revealed that age (OR = 2.7; 95% CI = 1.26-5.79; p = .01), menopausal status (OR = 2.29; 95% CI = 1.09-4.80; p = .03), dexamethasone dosage (OR = 2.1; 95% CI = 1.04-4.23; p = .03) and daily caloric intake (OR = 2.3; 95% CI = 1.12-5.10; p = .02) were independent variables that inducted weight gain. Pre- and post-menopausal women gained weight, but more pre-menopausal patients showed gain. An effort should be made to administer lower steroid doses to reduce weight gain. © 2016 John Wiley & Sons Ltd.

Preoperative chemotherapy (PC) for operable breast cancer has shown significant benefits in prospective trials. Many patients are treated in the community setting and some may question the applicability of PC outside the university setting. Retrospective review was performed of stage II and IIIA breast cancer patients treated from January 2002 to July 2009. Fifty-three of 57 patients who underwent PC were matched based on age, tumor size, and hormone receptor status with 53 patients who did not undergo PC. Differences in patient compliance with physician recommendations for all types of adjuvant therapy were evaluated. Crude odds ratios and adjusted odds ratios derived from conditional logistic regression models were calculated. There were 106 patients included. Patient compliance with chemotherapy was better in the PC group than in the adjuvant chemotherapy (AC) group (100% versus 70%; p = .0001). Similarly, more patients in the PC group completed radiation therapy (96% versus 65%; p = .0003) and initiated hormonal therapy (100% versus 62%; p = .0001). Conditional logistic regression revealed that higher pathologic stage and current cigarette smoking were associated with poorer compliance with chemotherapy. For radiation therapy, the univariate model revealed that compliance with chemotherapy and being employed were associated with completion of radiation, whereas current cigarette smoking and larger pathologic size were associated with poorer compliance with radiation. For hormonal therapy, current cigarette smokers were more likely to be noncompliant with initiation of hormonal therapy. PC for operable breast cancer can improve patient compliance with chemotherapy. Current cigarette smokers were more likely to be noncompliant with all types of adjuvant therapy.

BACKGROUND We sought to determine the effect of chemotherapy on the development of metabolic syndrome (MetS) in premenopausal and postmenopausal women undergoing (neo) adjuvant therapy for early stage breast cancer. METHODS Eighty-six women with early stage (I-III) breast cancer who were free from clinically diagnosed MetS (defined as three out of five components of MetS) were prospectively tested for presence of the five components of MetS within one week before initiating and after completing (neo) adjuvant chemotherapy. The five components of MetS measured were waist circumference, blood pressure, and fasting levels of blood glucose, triglycerides, and high-density lipoprotein cholesterol. Anthropometrics (body weight, percent body fat, fat mass), lipid profile (total cholesterol, low-density lipoprotein cholesterol), glucose metabolism (insulin, homeostatic model assessment-insulin resistance, glycated hemoglobin), and inflammation (C-reactive protein) were also examined before initiating and after completing treatment. RESULTS The study included 46 premenopausal and 40 postmenopausal women. All individual MetS components and overall MetS score were statistically significantly increased (p<0.01) after chemotherapy. Body weight, percent body fat, fat mass, lipids, glucose metabolism, and inflammation were also statistically significantly increased (p<0.01). CONCLUSION A 12–18 week course of chemotherapy statistically significantly increases MetS and related anthropometrics, biomarkers of glucose metabolism, and inflammation in early stage breast cancer patients with no pre-existing MetS. Lifestyle interventions such as diet and exercise may be preventive approaches to employ during chemotherapy to reduce the onset of MetS in breast cancer patients. PMID:27219902

Nutritional therapy is used to reduce the adverse events (AEs) of anticancer drugs. Here, we determined whether the amino acids cystine and theanine, which provide substrates for glutathione, attenuated the AEs of S-1 adjuvant chemotherapy. Patients scheduled to receive S-1 adjuvant chemotherapy were randomized to the C/T or the control groups. The C/T group received 700 mg cystine and 280 mg theanine orally 1 week before the administration of S-1, which then continued for 5 weeks. Each group received S-1 for 4 weeks. Blood sampling was performed and AEs were evaluated (CTCAE ver. 4.0) before and after the administration of S-1. S-1 was discontinued when AEs ≥ grade 2 occurred. The incidences of AEs of any grade and those over grade 2 were lower in the C/T group than in the controls. The incidence of diarrhea (G ≥ 2) was significantly less (p < 0.05) in the C/T group (3.1 %) than in the controls (25.8 %). The duration and completion rate of the S-1 adjuvant chemotherapy were significantly longer (p < 0.01) and higher (p < 0.01), respectively, in the C/T group (complete ratio: 75.0 %, duration: 24.8 ± 5.8 days) than in the controls (complete ratio: 35.5 %, duration: 20.0 ± 7.7 days). The oral administration of cystine and theanine attenuated the AEs of S-1 adjuvant chemotherapy and increased the S-1 completion rate, suggesting that cystine and theanine is a useful supportive care for chemotherapy.

The effectiveness of 5-fluorouracil (5-FU)-based adjuvant chemotherapy is reported in patients with colorectal cancer (CRC), but the usefulness of 5-FU metabolic enzymes as predictive biomarkers of the efficacy of this chemotherapy remains unclear. This study aims to verify whether 5-FU metabolic enzymes are predictive biomarkers in the clinical setting of adjuvant chemotherapy for stage II/III CRC. In total, 179 patients with stage II/III CRC who were treated at our institute between 2000 and 2010 were enrolled. Messenger RNA (mRNA) expression of major 5-FU metabolic enzymes, namely thymidylate synthase, dihydropyrimidine dehydrogenase, thymidine phosphorylase (TP), orotate phosphoribosyl transferase, and β-actin (control) was evaluated using the Danenberg Tumor Profile method. mRNA expression and other clinicopathological data were investigated with regard to CRC relapse. A total of 78 patients underwent surgery alone, while 101 underwent adjuvant chemotherapy (5-FU plus leucovorin [LV] or tegafur plus uracil /LV) following surgery. Relapse-free survival was longer and risk of recurrence was lower in association with high TP mRNA expression than in association with low TP mRNA expression in the adjuvant chemotherapy group (hazard ratio 0.66; 95 % confidence interval 0.47-0.92; p = 0.016), but not in the surgery alone group. mRNA expression of no other enzymes was associated with relapse in both groups. In decision-curve analyses, the predictive efficiency of TP mRNA expression plus clinicopathological factors was slightly better than that of clinicopathological factors only. TP mRNA expression in tumors predicted the effects of adjuvant chemotherapy for stage II/III CRC, although the beneficial effects were marginal.

'Taste' changes are commonly reported during chemotherapy. It is unclear to what extent this relates to actual changes in taste function or to changes in appetite and food liking and how these changes affect dietary intake and nutritional status. This prospective, repeated measures cohort study recruited participants from three oncology clinics. Women (n = 52) prescribed adjuvant chemotherapy underwent standardised testing of taste perception, appetite and food liking at six time points to measure change from baseline. Associations between taste and hedonic changes and nutritional outcomes were examined. Taste function was significantly reduced early in chemotherapy cycles (p<0.05) but showed recovery by late in the cycle. Ability to correctly identify salty, sour and umami tastants was reduced. Liking of sweet food decreased early and mid-cycle (p<0.01) but not late cycle. Liking of savory food was not significantly affected. Appetite decreased early in the cycle (p<0.001). Reduced taste function was associated with lowest kilojoule intake (r = 0.31; p = 0.008) as was appetite loss with reduced kilojoule (r = 0.34; p = 0.002) and protein intake (r = 0.36; p = 0.001) early in the third chemotherapy cycle. Decreased appetite early in the third and final chemotherapy cycles was associated with a decline in BMI (p = <0.0005) over the study period. Resolution of taste function, food liking and appetite was observed 8 weeks after chemotherapy completion. There was no association between taste change and dry mouth, oral mucositis or nausea. The results reveal, for the first time, the cyclical yet transient effects of adjuvant chemotherapy on taste function and the link between taste and hedonic changes, dietary intake and nutritional outcomes. The results should be used to inform reliable pre-chemotherapy education.

The risk of treatment-related death (TRD) and febrile neutropaenia (FN) with adjuvant taxane- based chemotherapy for early breast cancer is unknown in Malaysia despite its widespread usage in recent years. This study aims to determine these rates in patients treated in University Malaya Medical Centre (UMMC). Patients who were treated with adjuvant taxane-based chemotherapy for early breast cancer stages I, II or III from 2007-2011 in UMMC were identified from our UMMC Breast Cancer Registry. The TRD and FN rates were then determined retrospectively from medical records. TRD was defined as death occurring during or within 30 days of completing chemotherapy as a consequence of the chemotherapy treatment. FN was defined as an oral temperature >38.5°C or two consecutive readings of >38.0°C for 2 hours and an absolute neutrophil count <0.5x109/L, or expected to fall below 0.5x109/L. A total of 622 patients received adjuvant chemotherapy during this period. Of these patients 209 (33.6%) received taxane-based chemotherapy. 4 taxane-based regimens were used namely the FEC-D, TC, TAC and AC-PCX regimens. The commonest regimen employed was the FEC-D regimen accounting for 79.9% of the patients. The FN rate was 10% and there was no TRD. Adjuvant taxane-based chemotherapy in UMMC for early breast cancer has a FN rate of 10%. Primary prophylactic G-CSF should be considered for patients with any additional risk factor for FN.

The 21-gene assay (Oncotype DX Breast Cancer Test (Genomic Health Inc., Redwood City, CA)) is a well validated test that predicts the likelihood of adjuvant chemotherapy benefit and the 10-year risk of distant recurrence in patients with ER+, HER2- early-stage breast cancer. The aim of this analysis was to evaluate the cost-effectiveness of using the assay to inform adjuvant chemotherapy decisions in Germany. A Markov model was developed to make long-term projections of distant recurrence, survival, quality-adjusted life expectancy, and direct costs for patients with ER+, HER2-, node-negative, or up to 3 node-positive early-stage breast cancer. Scenarios using conventional diagnostic procedures or the 21-gene assay to inform treatment recommendations for adjuvant chemotherapy were modeled based on a prospective, multi-center trial in 366 patients. Transition probabilities and risk adjustment were based on published landmark trials. Costs (2011 Euros (€)) were estimated from a sick fund perspective based on resource use in patients receiving chemotherapy. Future costs and clinical benefits were discounted at 3% annually. The 21-gene assay was projected to increase mean life expectancy by 0.06 years and quality-adjusted life expectancy by 0.06 quality-adjusted life years (QALYs) compared with current clinical practice over a 30-year time horizon. Clinical benefits were driven by optimized allocation of adjuvant chemotherapy. Costs from a healthcare payer perspective were lower with the 21-gene assay by ∼€561 vs standard of care. Probabilistic sensitivity analysis indicated that there was an 87% probability that the 21-gene assay would be dominant (cost and life saving) to standard of care. Country-specific data on the risk of distant recurrence and quality-of-life were not available. Guiding decision-making on adjuvant chemotherapy using the 21-gene assay was projected to improve survival, quality-adjusted life expectancy, and be cost saving vs the current

Adjuvant chemotherapy for resected rectal cancer is widely used. However, studies on adjuvant treatment following neoadjuvant chemoradiotherapy (CRT) and total mesorectal excision (TME) have yielded conflicting results. Recent studies have focused on adding oxaliplatin to both preoperative and postoperative therapy, making it difficult to assess the impact of adjuvant oxaliplatin alone. This study was aimed at determining the impact of (i) any adjuvant treatment and (ii) oxaliplatin-containing adjuvant treatment on disease-free survival in CRT-pretreated, R0-resected rectal cancer patients. Patients undergoing R0 TME following 5-fluorouracil (5FU)-only-based CRT between January 1, 2008, and December 31, 2010, were selected from a nationwide registry. After propensity score matching (PSM), comparison of disease-free survival (DFS) using Kaplan-Meier analysis and log-rank test was performed in (i) patients receiving no vs. any adjuvant treatment and (ii) patients treated with adjuvant 5FU/capecitabine without vs. with oxaliplatin. Out of 1497 patients, 520 matched pairs were generated for analysis of no vs. any adjuvant treatment. Mean DFS was significantly prolonged with adjuvant treatment (81.8 ± 2.06 vs. 70.1 ± 3.02 months, p < 0.001). One hundred forty-eight matched pairs were available for analysis of adjuvant therapy with or without oxaliplatin, showing no improvement in DFS in patients receiving oxaliplatin (76.9 ± 4.12 vs. 79.3 ± 4.44 months, p = 0.254). Local recurrence rate was not significantly different between groups in either analysis. In this cohort of rectal cancer patients treated with neoadjuvant CRT and TME surgery under routine conditions, adjuvant chemotherapy significantly improved DFS. No benefit was observed for the addition of oxaliplatin to adjuvant chemotherapy in this setting.

For non-small cell lung cancer (NSCLC) patients at stage IB, adjuvant chemotherapy does not improve survival. Evidence suggests that dendritic cell (DC)-activated cytokine-induced killer (DC-CIK) cell therapy in addition to chemotherapy improves survival for stage I-IIIA NSCLC patients after surgery, but there are not enough data to confirm this benefit specifically for those at stage IB. Herein, we retrospectively evaluated the efficacy and safety of this therapy administered to stage IB NSCLC patients. Sixty-six patients were treated with four-cycle adjuvant chemotherapy initiated 3 weeks after surgical resection. In addition, 28 of these patients underwent DC-CIK therapy on a trimonthly basis (average 3.1 times, range 1-6) beginning 1 month after chemotherapy. The disease-free survival (DFS) rates of the two groups were statistically similar, although patients who received DC-CIK therapy showed slightly higher 1- and 2-year DFS rates (100.0% and 96.4%, respectively, compared with 81.6% and 76.3%). More importantly, patients in the DC-CIK therapy group had significantly longer overall survival (p=0.018). For patients who received treatment after recurrence, the DC-CIK therapy group had longer progression-free survival compared with the chemotherapy-only group. In addition, patients given DC-CIK therapy experienced less fatigue and appetite loss. The rate of adverse side effects was similar between the two groups. In conclusion, for these stage IB NSCLC patients, DC-CIK therapy significantly improved 2-year DFS rates compared with those who received chemotherapy only. DC-CIK therapy also benefited patients' quality of life, and adverse events were acceptable.

It has not been elucidated whether the clinical efficacy of oral fluoropyrimidines for adjuvant chemotherapy of colorectal cancer varies with tumor biological characteristics. A multicenter randomized trial was performed comparing oral tegafur/gimeracil/oteracil (S-1) and uracil-tegafur/ leucovorin (UFT/LV) as adjuvant therapy for stage III colorectal cancer. Postoperative survival was compared based on the 5-FU-related mRNA levels in cancer tissues. Among patients with tumor expressing dihydropyrimidine dehydrogenase (DPD) mRNA within the 66.7th percentile (lower 2/3) of all cases, overall survival (OS) was significantly better in the S-1 than in the UFT/LV group. In the S-1 group, patients with low DPD-expressing tumors had significantly better OS than those with highly expressing tumors. Patients with low thymidine synthase (TS)-expressing tumors had significantly better OS than those with highly expressing tumors. The efficacy of oral fluoropyrimidines as adjuvant chemotherapy for colorectal cancer may be influenced by the level of 5-FU-related mRNA in cancer tissues.

Purpose NCCTG (North Central Cancer Treatment Group) N9831 is the only randomized phase III trial evaluating trastuzumab added sequentially or used concurrently with chemotherapy in resected stages I to III invasive human epidermal growth factor receptor 2–positive breast cancer. Patients and Methods Patients received doxorubicin and cyclophosphamide every 3 weeks for four cycles, followed by paclitaxel weekly for 12 weeks (arm A), paclitaxel plus sequential trastuzumab weekly for 52 weeks (arm B), or paclitaxel plus concurrent trastuzumab for 12 weeks followed by trastuzumab for 40 weeks (arm C). The primary end point was disease-free survival (DFS). Results Comparison of arm A (n = 1,087) and arm B (n = 1,097), with 6-year median follow-up and 390 events, revealed 5-year DFS rates of 71.8% and 80.1%, respectively. DFS was significantly increased with trastuzumab added sequentially to paclitaxel (log-rank P < .001; arm B/arm A hazard ratio [HR], 0.69; 95% CI, 0.57 to 0.85). Comparison of arm B (n = 954) and arm C (n = 949), with 6-year median follow-up and 313 events, revealed 5-year DFS rates of 80.1% and 84.4%, respectively. There was an increase in DFS with concurrent trastuzumab and paclitaxel relative to sequential administration (arm C/arm B HR, 0.77; 99.9% CI, 0.53 to 1.11), but the P value (.02) did not cross the prespecified O'Brien-Fleming boundary (.00116) for the interim analysis. Conclusion DFS was significantly improved with 52 weeks of trastuzumab added to adjuvant chemotherapy. On the basis of a positive risk-benefit ratio, we recommend that trastuzumab be incorporated into a concurrent regimen with taxane chemotherapy as an important standard-of-care treatment alternative to a sequential regimen.

Background Many women with early-stage breast cancer are working at the time of diagnosis and survive without recurrence. The short-term impact of chemotherapy receipt on employment has been demonstrated, but the long-term impact merits further research. Methods We conducted a longitudinal multicenter cohort study of women diagnosed with non-metastatic breast cancer in 2005–2007, as reported to the population-based Los Angeles and Detroit SEER registries. Of 3133 individuals sent surveys, 2290 (73%) completed a baseline survey soon after diagnosis and 1536 (68%) completed a four-year follow-up questionnaire. Results Of the 1026 patients aged <65 at diagnosis whose breast cancer did not recur and who responded to both surveys, 746 (76%) worked for pay before diagnosis. Of these, 236 (30%) were no longer working at follow-up. Women who received chemotherapy as part of initial treatment were less likely to work at follow-up (38% vs. 27%, p=0.003). Chemotherapy receipt at the time of diagnosis (OR 1.4, p=0.04) was independently associated with unemployment during survivorship in a multivariable model. Many women who were not employed in the survivorship period wanted to work: 50% reported that it was important for them to work and 31% were actively seeking work. Conclusions Unemployment among breast cancer survivors four years after diagnosis is often undesired and appears related to the receipt of chemotherapy during initial treatment. These findings should be considered when patients decide whether to receive adjuvant chemotherapy, particularly when expected benefit is low. PMID:24777606

Purpose: To determine the effects of adjuvant radiotherapy and chemotherapy for carcinoma of the ampulla of Vater. Methods and Materials: We retrospectively reviewed the records of 125 patients who underwent definitive surgery for carcinomas involving the ampulla of Vater between April 1977 and February 2005 and who survived more than 50 days after surgery. Twenty-nine of the patients also received adjuvant radiotherapy (median dose, 50.4 Gy in 28 fractions) with concurrent 5-fluorouracil chemotherapy. Adverse prognostic factors were investigated, and overall survival (OS) and local and distant failure were estimated. Results: Adverse prognostic factors for decreased OS by univariate analysis includedmore » lymph node (LN) involvement, locally advanced tumors (T3/T4), and poor histologic grade. By multivariate analysis, positive LN status (p = 0.02) alone was associated with decreased OS. The addition of adjuvant radiotherapy and chemotherapy improved OS for patients with positive LN (p = 0.01). Median survival for positive LN patients receiving adjuvant therapy was 3.4 years, vs. 1.6 years for those with surgery alone. Conclusions: The addition of adjuvant radiotherapy and 5-fluorouracil chemotherapy may improve OS in patients with LN involvement. The effect of adjuvant therapy on outcomes for patients with poor histologic grade or T3/T4 tumors without LN involvement could not be assessed.« less

The aim of this multicenter study was to determine the appropriate administration schedule for S-1, an oral fluoropyrimidine, for adjuvant chemotherapy in patients with completely resected pathological-Stage IA (tumor diameter, 2-3 cm) non-small-cell lung cancer. Patients were randomly assigned to receive adjuvant chemotherapy consisting of either the 4-week oral administration of S-1 (80-120 mg/body/day) followed by a 2-week rest (Group A), or the 2-week oral administration of S-1 (80-120 mg/body/day) followed by a 1-week rest (Group B). The duration of adjuvant chemotherapy was 1 year in both arms. The primary endpoint was compliance, namely drug discontinuation-free survival, which was calculated using the Kaplan-Meier method with log-rank test. Eighty patients were enrolled in this study, and 76 patients actually received S-1 treatment. The drug discontinuation-free survival rates at 1 year were 49.1% in Group A and 52.7% in Group B (P = 0.373). The means of the relative dose intensities were 55.3% in Group A and 64.6% in Group B (P = 0.237). There were no treatment-related deaths. Patients with grade 3/4 toxicities were significantly more frequent in Group A (40.5%) than in Group B (15.4%, P = 0.021). The 2-year relapse-free survival rates were 97.5% in Group A and 92.5% in Group B, and the 2-year overall survival rates were 100% in both groups. The feasibility showed no significant difference between the two groups among patients with completely resected Stage IA (tumor diameter, 2-3 cm) non-small-cell lung cancer. © The Author 2016.

Background Epidermal growth factor receptor (EGFR) mutations occur in up to 50% of Asian patients with non-small cell lung cancer (NSCLC). Treatment of advanced NSCLC patients with EGFR-tyrosine kinase inhibitor (EGFR-TKI) confers a significant survival benefit. This study assessed the efficacy and safety of chemotherapy with or without icotinib in patients undergoing resection of stage IB to ⅢA EGFR-mutated NSCLC. Methods Patients with surgically resected stage IB (with high risk factors) to ⅢA EGFR-mutated NSCLC were randomly assigned (1:1) to one of two treatment plans. One group received four cycles of platinum-based doublet chemotherapy every three weeks, and the other group received platinum-based chemotherapy supplemented with consolidation therapy of orally administered icotinib (125 mg thrice daily) two weeks after chemotherapy. The icotinib treatment continued for four to eight months, or until the occurrence of disease relapse, metastasis or unacceptable icotinib or chemotherapy toxicity. The primary endpoint was disease-free survival (DFS). Results 41 patients were enrolled between Feb 9, 2011 and Dec 17, 2012. 21 patients were assigned to the combined chemotherapy plus icotinib treatment group, while 20 patients received chemotherapy only. DFS at 12 months was 100% for icotinib-treated patients and 88.9% for chemotherapy-only patients (p = 0. 122). At 18 months DFS for icotinib-treated vs. chemotherapy-only patients was 95.2% vs. 83.3% (p = 0. 225), respectively, and at 24 months DFS was 90.5% vs. 66.7% (p = 0. 066). The adverse chemotherapy effects predominantly presented as gastrointestinal reactions and marrow suppression, and there was no significant difference between the two treatment groups. Patients in the chemotherapy plus icotinib treatment group showed favorable tolerance to oral icotinib. Conclusions The results suggest that chemotherapy plus orally icotinib displayed better DFS compared with chemotherapy only, yet the difference in DFS

The aim was to evaluate the physical activity intensity (PAI) of patients receiving adjuvant chemotherapy and investigate the relationship between health status perception and PAI in Japan. Consenting participants of this prospective, descriptive, repeated measures design were 28 women aged 20-64 with stage I-IIIA initial breast cancer whose regimen included anthracycline. Participants wore a triaxial accelerometer and their PAI was measured for a 14-day period at the beginning of chemotherapy. The SF-36 Survey and Cancer Fatigue Scale were administered. The accelerometer was used to calculate the number of steps, physical activity level (PAL) and total minutes of PAI levels of under 1.5 Mets, 1.5-2.9 Mets, and more than 3.0 Mets during the first half (FH; days 2-7) and second half (SH; days 8-14) of the study. Data were analyzed using Pearson's correlation coefficient and multiple regression analysis. During FH, the mean number of steps was 3841.1 steps/day and mean PAL was 1.43; during SH, the mean number of steps was 4058.4 steps/day, mean PAL was 1.43; participants spent over 70% of the day working quietly in a sitting position. PAL during SH was significantly associated with mean time spent during activities of 1.5-2.9 Mets (β = 0.880, p < 0.0001) and 3.0 Mets (β = 0.268, p < 0.0001). Patients receiving adjuvant chemotherapy had extremely low physical activity. They should be provided useful information of appropriate physical movement and be supported in resolving physical and psychological distress. Copyright © 2013 Elsevier Ltd. All rights reserved.

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

Background 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. Methods 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. Results 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

Several large, randomized trials established the benefits of adjuvant trastuzumab with chemotherapy. However, the benefit for women with small, node-negative HER2-positive (HER2+) disease is unknown, as these patients were largely excluded from these trials. Therefore, a retrospective, single-institution, sequential cohort study of women with small, node-negative, HER2+ breast cancer who did or did not receive adjuvant trastuzumab was conducted. Women with ≤ 2 cm, node-negative, HER2+ (immunohistochemistry 3+ or fluorescence in situ hybridization ≥ 2) breast cancer were identified through an institutional database. A "no-trastuzumab" cohort of 106 trastuzumab-untreated women diagnosed between January 1, 2002 and May 14, 2004 and a "trastuzumab" cohort of 155 trastuzumab-treated women diagnosed between May 16, 2005 and December 31, 2008 were described. Survival and recurrence outcomes were estimated by Kaplan-Meier methods. The cohorts were similar in age, median tumor size, histology, hormone receptor status, hormone therapy, and locoregional therapy. Chemotherapy was administered in 66% and 100% of the "no trastuzumab" and "trastuzumab" cohorts, respectively. The median recurrence-free and survival follow-up was: 6.5 years (0.7-8.5) and 6.8 years (0.7-8.5), respectively, for the "no trastuzumab" cohort and 3.0 years (0.5-5.2) and 3.0 years (0.6-5.2), respectively, for the "trastuzumab" cohort. The 3-year locoregional invasive recurrence-free, distant recurrence-free, invasive disease-free, and overall survival were 92% versus 98% (P = .0137), 95% versus 100% (P = .0072), 82% versus 97% (P < .0001), and 97% versus 99% (P = .18) for the "no trastuzumab" and "trastuzumab" cohorts, respectively. Women with small, node-negative, HER2+ primary breast cancers likely derive significant benefit from adjuvant trastuzumab with chemotherapy. Copyright © 2011 American Cancer Society.

With the increasing use of adjuvant chemotherapy for treating early breast cancer, febrile neutropenia management has become crucial. Guidelines for febrile neutropenia management are mostly based on a Caucasian population survey although ethnic differences are reported in terms of adverse events. We survey the current status of febrile neutropenia and risk factors in Japanese female breast cancer patients receiving neoadjuvant and adjuvant chemotherapy regimens potential for febrile neutropenia. Subsequently, we plan to conduct a multicenter prospective cohort study involving 1000 patients with operable breast cancer. With the current state of oral antibiotics being routinely prescribed without hematology tests, we survey febrile neutropenia based on two different definitions, namely, true febrile neutropenia: ≥37.5°C and Grade 4 neutropenia, and surrogate febrile neutropenia: ≥37.5°C and oral antibiotic and antipyretic intake. The comparison of true febrile neutropenia and surrogate febrile neutropenia incidences is anticipated to provide information on the safety and feasibility of chemotherapy management without performing blood tests. © The Author 2016.

The Effect of Mindfulness-Based Music Therapy on Attention and Mood in Women Receiving Adjuvant Chemotherapy for Breast Cancer: A Pilot Study.

PubMed

Lesiuk, Teresa

2015-05-01

To explore the efficacy of mindfulness-
based music therapy (MBMT) to improve attention and decrease mood distress experienced by women with breast cancer receiving adjuvant chemotherapy. Quantitative, descriptive, longitudinal approach. A comprehensive cancer hospital and a university in southern Florida. 15 women with a diagnosis of breast cancer, stages I-III, receiving adjuvant chemotherapy. Participants individually received MBMT for one hour per week for four weeks. The sessions consisted of varied music activities accompanied by mindfulness attitudes, or mental strategies that enhance moment-to-moment awareness, and weekly homework. Demographic information was collected at baseline. Attention was measured using Conners' Continuous Performance Test II. Mood was measured using the Profile of Mood States-Brief Form. Narrative comments collected from the homework assignments served to reinforce quantitative data. Repeated measures analysis of variance showed that attention improved significantly over time. Although all mood states significantly improved from the beginning to the end of each MBMT session, the mood state of fatigue decreased significantly more than the other mood states. MBMT enhances attention and mood, particularly the mood state of fatigue, in women with breast cancer receiving adjuvant chemotherapy. 
. A preferred music listening and mindfulness exercise may be offered to women with breast cancer who experience attention problems and mood distress.

Epidermal growth factor receptor (EGFR) mutations occur in up to 50% of Asian patients with non-small cell lung cancer (NSCLC). Treatment of advanced NSCLC patients with EGFR-tyrosine kinase inhibitor (EGFR-TKI) confers a significant survival benefit. This study assessed the efficacy and safety of chemotherapy with or without icotinib in patients undergoing resection of stage IB to ⅢA EGFR-mutated NSCLC. Patients with surgically resected stage IB (with high risk factors) to ⅢA EGFR-mutated NSCLC were randomly assigned (1:1) to one of two treatment plans. One group received four cycles of platinum-based doublet chemotherapy every three weeks, and the other group received platinum-based chemotherapy supplemented with consolidation therapy of orally administered icotinib (125 mg thrice daily) two weeks after chemotherapy. The icotinib treatment continued for four to eight months, or until the occurrence of disease relapse, metastasis or unacceptable icotinib or chemotherapy toxicity. The primary endpoint was disease-free survival (DFS). 41 patients were enrolled between Feb 9, 2011 and Dec 17, 2012. 21 patients were assigned to the combined chemotherapy plus icotinib treatment group, while 20 patients received chemotherapy only. DFS at 12 months was 100% for icotinib-treated patients and 88.9% for chemotherapy-only patients (p = 0. 122). At 18 months DFS for icotinib-treated vs. chemotherapy-only patients was 95.2% vs. 83.3% (p = 0. 225), respectively, and at 24 months DFS was 90.5% vs. 66.7% (p = 0. 066). The adverse chemotherapy effects predominantly presented as gastrointestinal reactions and marrow suppression, and there was no significant difference between the two treatment groups. Patients in the chemotherapy plus icotinib treatment group showed favorable tolerance to oral icotinib. The results suggest that chemotherapy plus orally icotinib displayed better DFS compared with chemotherapy only, yet the difference in DFS was not significant. We would think

Review of Adjuvant Radiochemotherapy for Resected Pancreatic Cancer and Results From Mayo Clinic for the 5th JUCTS Symposium

2009-10-01

Purpose: To present an overview of Phase III trials in adjuvant therapy for pancreatic cancer and review outcomes at the Mayo Clinic after adjuvant radiochemotherapy (RT/CT) for resected pancreatic cancer. Methods and Materials: A literature review and a retrospective review of 472 patients who underwent an R0 resection for T1-3N0-1M0 invasive carcinoma of the pancreas from 1975 to 2005 at the Mayo Clinic, Rochester, MN. Patients with metastatic or unresectable disease at the time of surgery, positive surgical margins, or indolent tumors and those treated with intraoperative radiotherapy were excluded from the analysis. Median radiotherapy dose was 50.4Gy in 28more » fractions, with 98% of patients receiving concurrent 5-fluorouracil- based chemotherapy. Results: Median follow-up was 2.7 years. Median overall survival (OS) was 1.8 years. Median OS after adjuvant RT/CT was 2.1 vs. 1.6 years for surgery alone (p = 0.001). The 2-y OS was 50% vs. 39%, and 5-y was 28% vs. 17% for patients receiving RT/CT vs. surgery alone. Univariate and multivariate analysis revealed that adverse prognostic factors were positive lymph nodes (risk ratio [RR] 1.3, p < 0.001) and high histologic grade (RR 1.2, p < 0.001). T3 tumor status was found significant on univariate analysis only (RR 1.1, p = 0.07). Conclusions: Results from recent clinical trials support the use of adjuvant chemotherapy in resected pancreatic cancer. The role of radiochemotherapy in adjuvant treatment of pancreatic cancer remains a topic of debate. Results from the Mayo Clinic suggest improved outcomes after the administration of adjuvant radiochemotherapy after a complete resection of invasive pancreatic malignancies.« less

Breast cancer is a disease of ageing. Functional independence in elderly patients, measured with the Katz activities of daily living (ADL) scale, predicts overall survival and the need for welfare support. Few prospective studies have examined the feasibility of adjuvant chemotherapy and its impact on autonomy in women over 70 years of age with high-risk breast cancer. This multicentre phase II trial was designed to assess the impact of adjuvant anthracycline-based chemotherapy on these patients' autonomy. In a two-stage Fleming design, women aged ≥70 years with histologically proven hormone-receptor-negative early breast cancer and a significant risk of recurrence (pN+ or "high risk" pN0) received 4 cycles of nonpegylated liposomal doxorubicin 60 mg/m(2) and cyclophosphamide 600 mg/m(2) every 3 weeks postoperatively, on an outpatient basis. The primary endpoint was the change in the ADL score during chemotherapy. Secondary endpoints include comprehensive geriatric, quality-of-life and acceptability assessments, tolerability, and long-term outcome. The results for the primary endpoint and other scales at completion of adjuvant chemotherapy are reported here, while long-term follow-up is not yet complete. Forty patients (median age 75 [70-82]) were enrolled between February 2006 and November 2007. Chemotherapy had no deleterious impact on ADL, cognition, mental status, or the frequency of comorbidities. In contrast, the number of patients at risk of malnutrition, based on the Mini Nutritional Assessment, more than doubled between baseline and the end of chemotherapy, rising from 15% to 38%. Quality-of-life deteriorated in terms of social and role functioning, likely owing to fatigue, loss of appetite, nausea and vomiting. Treatment acceptability was good. The main adverse effect was neutropenia, 15% of the patients experiencing febrile neutropenia. No cardiac toxicity or toxic deaths occurred. This study demonstrates the feasibility of an adjuvant chemotherapy

Purpose To perform an exploratory analysis of the relationship between gene expression and recurrence in patients with operable triple negative breast cancer (TNBC) treated with adjuvant doxorubicin-containing chemotherapy. Experimental design RNA was extracted from archived tumor samples derived from 246 patients with stage I-III TNBC treated with adjuvant doxorubicin-containing chemotherapy, and was analyzed by quantitative RT-PCR for a panel of 374 genes. The relationship between gene expression and recurrence was evaluated using weighted Cox proportional hazards model score tests. Results GRB7 was the only gene for which higher expression was significantly associated with increased recurrence in TNBC (Korn’s adjusted p value=0.04). In a Cox proportional hazards model adjusted for clinicopathologic features, higher GRB7 expression was associated with an increased recurrence risk (HR 2.31, p=0.04 using the median as the split). The 5-year recurrence rates were 10.5% (95% confidence intervals [CI] 7.8%, 14.1%) in the low and 20.4% (95% CI 16.5%, 25.0%) in the high GRB7 groups. External validation in other datasets indicated that GRB7 expression was not prognostic in two adjuvant trials including variable systemic therapy, but in two other trials showed that high GBR7 expression was associated with resistance to neoadjuvant doxorubicin and taxane therapy. Conclusions GRB7 was associated with an increased risk of recurrence in TNBC, suggesting that GRB7 or GRB7-dependent pathways may serve as potential biomarkers for therapeutic targets. Therapeutic targeting of one or more factors identified which function as interaction nodes or effectors should also be considered. PMID:21933890

Resected non-small cell lung cancer (NSCLC) has 5-years survival rates of 30-70%. The role of adjuvant chemotherapy remains unclear with poor compliance reported in most trials. The compliance with adjuvant chemotherapy (ACT) for stage IB and II NSCLC was analyzed using data from a North American multi-centre phase III study (accrual 1994-2001) that compared adjuvant chemotherapy to observation. Planned chemotherapy consisted of cisplatin (CIS) 50 mg/m2 days 1, 8 and vinorelbine (VIN) 25 mg/m2 days 1, 8, 15, 22 for four cycles; the VIN dose had been reduced from 30 mg/m2 after an initial cohort of patients experienced unacceptable toxicity. Four hundred and twenty-four patients were randomized after the amendment, 215 to the chemotherapy arm. Median age was 60 years, 64% were male and 84% had stage II disease. Thirty-seven patients completed one cycle, 14 completed two, 20 completed three and 108 patients completed all four cycles. Ten patients received no therapy. Multivariate analysis demonstrated statistically significant differences in compliance with extent of surgery, gender and age. Patients randomized in Canada were more likely to fail to complete chemotherapy due to refusal of therapy than their American counterparts. Patients who had pneumonectomies were more likely to discontinue therapy due to toxicity than those who had lesser resections. Extent of surgery may play a role in both the compliance and toxicity of ACT. Differences between nations in the perception of the risks and benefits of adjuvant chemotherapy regimens, both between physicians and patients, should be investigated further.

To develop a computerised decision aid (DA) to inform the decision process on adjuvant chemotherapy in patients with stage II colorectal cancer, and examine perceived usefulness, acceptability and areas for improvement of the DA. Mixed methods. Single outpatient oncology department in central London. Consecutive recruitment of 13 patients with stage II colorectal cancer, 12 of whom completed the study. Inclusion criteria were: age >18 years; complete resection for stage II adenocarcinoma of the colon or rectum; patients within 14-56 days after surgery; no contraindication to adjuvant chemotherapy; able to give written informed consent. Exclusion criterion: previous chemotherapy. Patient perceived usefulness (assessed by the PrepDM questionnaire) and acceptability of the DA. PrepDM scores, measuring the perceived usefulness of the DA in preparing the patient to communicate with their doctor and make a health decision, were above those reported in other patient groups. Patient acceptability scores were also high; however, interviews showed that there was evidence of a lack of understanding of key information among some patients, in particular their baseline risk of recurrence, the net benefit of combination chemotherapy and the rationale for having chemotherapy when cancer had apparently gone. Patients found the DA acceptable and useful in supporting their decision about whether or not to have adjuvant chemotherapy. Suggested improvements for the DA include: sequential presentation of treatment options (eg, no treatment vs 1 drug, 1 drug vs 2 drugs) to enhance patient understanding of the difference between combination and single therapy, diagrams to help patients understand the rationale for chemotherapy to prevent a recurrence and inbuilt checks on patient understanding of baseline risk of recurrence and net benefit of chemotherapy.

The present study investigated the effect of adjuvant chemotherapy and radiation on survival among patients undergoing chest wall resection for T3N0 non-small cell lung cancer (NSCLC). Patients with T3N0 NSCLC who underwent chest wall resection were identified in the National Cancer Data Base in 2004 to 2012. The cohort was divided into patients who had received adjuvant chemotherapy, radiation therapy, chemoradiation therapy, or no adjuvant treatment. Kaplan-Meier and log-rank tests were used to compare overall survival, and a bootstrapped Cox proportional hazards model was used to determine the significant contributors to survival. A subset analysis was performed with stratification by margin status and tumor size. Of 759 patients identified, 42.0% underwent surgery alone, 23.3% underwent surgery followed by chemotherapy, 22.3% underwent surgery followed by chemoradiation therapy, and 12.3% underwent surgery followed by radiotherapy alone. Tumors > 4 cm benefited from adjuvant chemotherapy and radiation therapy in the multivariable analysis, and those ≤ 4 cm benefited only from adjuvant chemotherapy. The subgroup analysis by margin status identified that margin-positive patients with tumors > 4 cm benefited significantly from either adjuvant chemoradiation therapy or radiation therapy alone. T3N0 NSCLC with chest wall invasion requires unique management compared with other stage IIB tumors. An important determinant of management is tumor size, with tumors ≤ 4 cm benefiting from adjuvant chemotherapy and tumors > 4 cm benefiting from adjuvant chemotherapy if margin negative and adjuvant chemoradiation therapy or radiotherapy if margin positive.

It has been proved that trastuzumab has clinical activity in early and advanced breast cancer with Her2-overexpression. This study was to analyze the safety of trastuzumab after adjuvant chemotherapy in 30 Chinese Her2-positive early breast cancer patients. Trastuzumab was administrated after adjuvant chemotherapy every 21 days. The initial dose was 8 mg/kg, and the subsequent dose was 6 mg/kg, for four to 35 cycles (medium 18 cycles). The side effects of these patients, especially cardiotoxicity, were analyzed. Thirty patients with Her2-positive early breast cancer were entered into the study. The average treatment period was one year (range nine weeks to two years). Two patients had shivering and fever during the first infusion with trastuzumab. Left ventricular ejection fraction (LVEF) level dropped in 18 cases after treatment with trastuzumab, half of which decreased more then 10%û however, no cardiac failure was observed. The post-surgical treatment of trastuzumab in Chinese patients with Her2-positive early breast cancer shows a satisfactory safety profile. However, the potential cardiotoxicity of trastuzumab should be carefully monitored during therapy.

Singapore Cancer Network (SCAN) Guidelines for Adjuvant Chemotherapy in Resected Non-Small Cell Lung Cancer.

2015-10-01

The SCAN lung cancer workgroup aimed to develop Singapore Cancer Network (SCAN) clinical practice guidelines for the use of adjuvant systemic therapy for non-small cell lung cancer in Singapore. The workgroup utilised a modified ADAPTE process to calibrate high quality international evidence-based clinical practice guidelines to our local setting. Five international guidelines were evaluated- those developed by the National Comprehensive Cancer Network (2014), European Society of Medical Oncology (2014), National Institute of Clinical Excellence (2012), Scottish Intercollegiate Guidelines Network (2014), and the Cancer Care Council Australia (2012). Recommendations on the selection of patients, chemotherapy regimen, treatment for stage I disease, treatment for positive margins and treatment options for pN2 disease with negative margins were produced. These adapted guidelines form the SCAN Guidelines 2015 for adjuvant systemic therapy of non-small cell lung cancer.

Cognitive decline is among the most feared treatment-related outcomes of older adults with cancer. The majority of older patients with breast cancer self-report cognitive problems during and after chemotherapy. Prior neuroimaging research has been performed mostly in younger patients with cancer. The purpose of this study was to evaluate longitudinal changes in brain volumes and cognition in older women with breast cancer receiving adjuvant chemotherapy. Women aged ≥ 60 years with stage I-III breast cancer receiving adjuvant chemotherapy and age-matched and sex-matched healthy controls were enrolled. All participants underwent neuropsychological testing with the US National Institutes of Health (NIH) Toolbox for Cognition and brain magnetic resonance imaging (MRI) prior to chemotherapy, and again around one month after the last infusion of chemotherapy. Brain volumes were measured using Neuroreader™ software. Longitudinal changes in brain volumes and neuropsychological scores were analyzed utilizing linear mixed models. A total of 16 patients with breast cancer (mean age 67.0, SD 5.39 years) and 14 age-matched and sex-matched healthy controls (mean age 67.8, SD 5.24 years) were included: 7 patients received docetaxel and cyclophosphamide (TC) and 9 received chemotherapy regimens other than TC (non-TC). There were no significant differences in segmented brain volumes between the healthy control group and the chemotherapy group pre-chemotherapy (p > 0.05). Exploratory hypothesis generating analyses focusing on the effect of the chemotherapy regimen demonstrated that the TC group had greater volume reduction in the temporal lobe (change = - 0.26) compared to the non-TC group (change = 0.04, p for interaction = 0.02) and healthy controls (change = 0.08, p for interaction = 0.004). Similarly, the TC group had a decrease in oral reading recognition scores (change = - 6.94) compared to the non-TC group (change = - 1.21, p for

The purpose of this study was to conduct an exploratory analysis of the START examining the effects of resistance exercise training (RET) and aerobic exercise training (AET) on sarcopenia, dynapenia, and associated quality of life (QoL) changes in breast cancer (BC) patients receiving adjuvant chemotherapy. Participants were randomized to usual care (UC) (n = 70), AET (n = 64), or RET (n = 66) for the duration of chemotherapy. Measures of sarcopenia [skeletal muscle index (SMI)] and dynapenia [upper extremity (UE) and lower extremity (LE) muscle dysfunction (MD)] were normalized relative to age-/sex-based clinical cut-points. QoL was assessed by the Functional Assessment of Cancer Therapy-Anemia (FACT-An) scales. At baseline, 25.5 % of BC patients were sarcopenic and 54.5 % were dynapenic with both conditions associated with poorer QoL. ANCOVAs showed significant differences favoring RET over UC for SMI (0.32 kg/m(2); p = 0.017), UE-MD (0.12 kg/kg; p < 0.001), and LE-MD (0.27 kg/kg; p < 0.001). Chi-square analyses revealed significant effects of RET, compared to UC/AET combined, on reversing sarcopenia (p = 0.039) and dynapenia (p = 0.019). The reversal of sarcopenia was associated with clinically relevant improvements in the FACT-An (11.7 points [95 % confidence interval (CI) -4.2 to 27.6]), the Trial Outcome Index-Anemia (10.0 points [95 % CI -4.0 to 24.1]), and fatigue (5.3 points [95 % CI -1.5 to 12.1]). Early-stage BC patients initiating adjuvant chemotherapy have higher than expected rates of sarcopenia and dynapenia which are associated with poorer QoL. RET during adjuvant chemotherapy resulted in the reversal of both sarcopenia and dynapenia; however, only the reversal of sarcopenia was associated with clinically meaningful improvements in QoL.

The goal of this study was to characterize changes in daily fatigue in women undergoing chemotherapy for breast cancer. We examined whether there are subgroups of patients with distinct fatigue trajectories and explored potential psychosocial and biomedical predictors of these subgroups. Participants were 77 women with breast cancer receiving adjuvant chemotherapy with AC-T (2-week cycle) and TC or TCH (3-week cycle) regimens. They completed 28 daily ratings online using an adapted version of the Patient-Reported Outcomes Measurement Information System (PROMIS®) fatigue instrument. Both regimens followed an "inverted-U-shaped" fatigue pattern over approximately 2 weeks. Growth mixture modeling identified three patient subgroups with distinct trajectories. Fatigue scores in the "low fatigue" group (23 %) increased following the infusion and quickly abated. The "transient fatigue" (27 %) group had a very pronounced increase. Patients in the "high fatigue" (50 %) group reported consistently elevated fatigue with a relatively small increase. Demographic and medical variables were not associated with fatigue trajectory. Patients in the "high fatigue" group reported significantly poorer physical, emotional, and social functioning, poorer general health, and more depressed mood than patients in the "low fatigue" group. The "transient fatigue" group reported significantly better physical and social functioning than the "high fatigue" group, but emotional distress and depression similar to the "high fatigue" group. The identification of patient subgroups with distinct fatigue trajectories during chemotherapy is an essential step for developing preventative strategies and tailored interventions. Our results suggest that different trajectories are associated with patients' psychosocial and general health.

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

Due to its frequency and persistently high mortality, colorectal cancer represents a major public health problem. The use of adjuvant chemotherapy has improved prognosis in stage III disease, but much work remains to be done in optimizing adjuvant treatment, including refinement of ability to predict disease course and response to chemotherapy. The FOLFOX4 regimen is now considered standard treatment for stage III disease. Combinations of irinotecan and 5-fluorouracil (5-FU) have not proven to be more effective than 5-FU/folinic acid (FA). Oral fluoropyrimidines (eg, capecitabine, UFT + FA) now offer an alternative to intravenous 5-FU. Adjuvant chemotherapy for stage II colorectal cancer is more controversial. Use of adjuvant chemotherapy does not appear to be justified in patients with no particular risk factors (T3N0 with no poor prognosis factor). In contrast, the risk:benefit ratio in patients with one or more poor prognostic factors (T4 tumor, occlusion or perforation, poorly differentiated tumor, vascular invasion, or < 10 lymph nodes examined) appears to favor adjuvant treatment with FOLFOX4. Ongoing adjuvant trials are evaluating bevacizumab and cetuximab combined with 5-FU and oxaliplatin, and are examining the utility of such potential predictive markers as tumor microsatellite instability and loss of heterozygosity. Duration of therapy and prevention of oxaliplatin neurotoxicity are other critical areas for future research. PMID:19262714

Perioperative chemotherapy more of a benefit for overall survival than adjuvant chemotherapy for operable gastric cancer: an updated Meta-analysis

To clarify the effect of neoadjuvant chemotherapy (NAC) on the survival outcomes of operable gastric cancers, we searched PubMed, Embase, and Cochrane Library for randomized clinical trials published until June 2014 that compared NAC-containing strategies with NAC-free strategies in patients with adenocarcinoma of the stomach or the esophagogastric junction, who had undergone potentially curative resection. The adjusted pooled hazard ratio (HR) for overall survival (OS) was insignificant when comparing the NAC-containing arm with the NAC-free arm. Subgroup analysis showed that the OS of the treatment arm that involved both adjuvant chemotherapy (AC) and NAC was significantly improved over the control arm (AC only) (HR = 0.48, 95% CI: 0.35–0.67; P < 0.001). While NAC alone plus surgery did not show any survival benefit over surgery alone. Perioperative chemotherapy (PC) also showed a significant increase in PFS and a significant reduction in distant metastasis compared to surgery alone. Therefore, in patients with resectable gastric cancer, NAC alone is not enough and AC alone is not good enough to definitely improve their OS. Collectively, PC combined with surgery could maximize the survival benefit for patients with resectable gastric cancer. PMID:26242393

In high-grade musculoskeletal sarcomas, adjuvant chemotherapy is often performed to prevent distant metastases. As the efficacy of chemotherapy varies according to the histological type of sarcoma, its indication is determined according to the histological type and the stage. Prognoses are poor in patients with osteosarcoma, Ewing's sarcoma, or rhabdomyosarcoma, when surgery alone is performed. However, because these sarcomas are chemosensitive, their prognoses are improved with adjuvant chemotherapy, so it is absolutely necessary. Drugs commonly used for osteosarcoma include adriamycin, cisplatin, methotrexate, vincristine, and ifosfamide. For Ewing's sarcoma and rhabdomyosarcoma, vincristine, actinomycin-D, cyclophosphamide, etoposide, and ifosfamide are commonly used. On the other hand, the efficacy of chemotherapy is unclear in most of the non-round cell sarcomas, e. g., malignant fibrous histiocytoma, pleomorphic liposarcoma, and leiomyosarcoma, so adjuvant chemotherapy is relatively indicated and often performed preoperatively. The efficacy is evaluated by reduction of the tumor volume as a surrogate marker. Postoperative chemotherapy is performed when the preoperative chemotherapy is effective. Nowadays, several kinds of antitumor agents are usually used for non-round cell sarcomas, and many authors have reported various kinds of regimens and their clinical results. Among them, the key drugs are adriamycin and ifosfamide. Recently, taxanes and gemcitabine are sometimes used. For chemoresistant sarcomas, e. g., chondrosarcoma, chordoma, alveolar soft part sarcoma, chemotherapy is rarely indicated, even if the tumor is histologically high grade and large. Low-grade musculoskeletal sarcomas, e. g., low-grade chondrosarcoma, central low-grade osteosarcoma, parosteal osteosarcoma, well-differentiated liposarcoma, and dermatofibrosarcoma protuberans, are well cured only by surgical excision, and adjuvant chemotherapy is therefore not indicated.

Adjuvant Therapy for Stage II Colorectal Cancer: Who and with What?

PubMed

Chung, Ki-Young Y; Kelsen, David

2006-06-01

The role of adjuvant chemotherapy for patients with stage II colon adenocarcinoma remains controversial. The high surgical cure rate for patients with "low-risk" stage II colon cancer, ranging from 75% to 80%, and the available clinical trials and meta-analyses provide conflicting recommendations for or against adjuvant chemotherapy for this group of patients. For fit "high-risk" stage II patients with clinical obstruction or perforation at presentation, in which the 5-year survival rate is 60% to 70%, there is little controversy, as these patients are routinely treated with adjuvant chemotherapy. Other potential high-risk factors, including high histologic grade, microsatellite instability, and loss of 18q, have yet to be validated in prospective trials. Patients with fewer than 12 regional lymph nodes identified in the surgical specimen have a statistically unclear risk of lymph node involvement. These patients may have stage III disease and should receive adjuvant therapy. The decision to use adjuvant chemotherapy to treat low-risk stage II colon cancer patients (no obstruction or perforation) should be an informed decision weighing the magnitude of a net 2% to 5% survival benefit, a 0.5% to 1.0% risk of mortality with chemotherapy in addition to 6 months of chemotherapy-related toxicities, other coexisting patient morbidities, and the anticipated life expectancy of each patient. As adjuvant chemotherapy is therapy addressing local or metastatic microscopic disease, and the effectiveness of systemic and biologically targeted therapy for advanced macroscopic colon cancer continues to improve rapidly, it remains to be determined by clinical trials whether therapies including newer agents such as cetuximab and bevacizumab administered in the adjuvant setting may affect survival for stage II cancer patients.

Patients with periampullary adenocarcinomas undergo the same resectional surgery as that of patients with pancreatic ductal adenocarcinoma. Although adjuvant chemotherapy has been shown to have a survival benefit for pancreatic cancer, there have been no randomized trials for periampullary adenocarcinomas. To determine whether adjuvant chemotherapy (fluorouracil or gemcitabine) provides improved overall survival following resection. The European Study Group for Pancreatic Cancer (ESPAC)-3 periampullary trial, an open-label, phase 3, randomized controlled trial (July 2000-May 2008) in 100 centers in Europe, Australia, Japan, and Canada. Of the 428 patients included in the primary analysis, 297 had ampullary, 96 had bile duct, and 35 had other cancers. One hundred forty-four patients were assigned to the observation group, 143 patients to receive 20 mg/m2 of folinic acid via intravenous bolus injection followed by 425 mg/m2 of fluorouracil via intravenous bolus injection administered 1 to 5 days every 28 days, and 141 patients to receive 1000 mg/m2 of intravenous infusion of gemcitabine once a week for 3 of every 4 weeks for 6 months. The primary outcome measure was overall survival with chemotherapy vs no chemotherapy; secondary measures were chemotherapy type, toxic effects, progression-free survival, and quality of life. Eighty-eight patients (61%) in the observation group, 83 (58%) in the fluorouracil plus folinic acid group, and 73 (52%) in the gemcitabine group died. In the observation group, the median survival was 35.2 months (95%% CI, 27.2-43.0 months) and was 43.1 (95%, CI, 34.0-56.0) in the 2 chemotherapy groups (hazard ratio, 0.86; (95% CI, 0.66-1.11; χ2 = 1.33; P = .25). After adjusting for independent prognostic variables of age, bile duct cancer, poor tumor differentiation, and positive lymph nodes and after conducting multiple regression analysis, the hazard ratio for chemotherapy compared with observation was 0.75 (95% CI, 0.57-0.98; Wald χ2 = 4

To investigate chemokine receptor CXCR1 expression characteristic in different breast tissues and analyze the relationship between CXCR1 expression changes in breast cancer tissue and efficacy of neo-adjuvant chemotherapy. Chemokine receptor CXCR1 was lowly expressed in normal breast tissues and breast fibroadenoma, but highly expressed in breast cancer. It was significantly correlated with pathological stage, tumor cell differentiation, and lymph node metastasis (P < 0.05). After neo-adjuvant chemotherapy, CXCR1 expression in breast cancer tissues decreased. Among these 104 breast cancer patients with different molecular subtypes, the survival rate with Luminal A was the highest, followed by the Luminal B breast cancer, TNBC was the worst. 104 cases with breast carcinoma, 20 cases with normal breast and 20 cases with breast fibroadenoma were included and followed up. Immunohistochemistry was used to detect the expression of CXCR1 in the various tissues. The relationship between the CXCR1 expression changes in breast cancer biopsies and surgical specimens, as well as the efficacy of neo-adjuvant chemotherapy, was analyzed. Chemokine receptor CXCR1 could be used as an indicator to predict benign or malignant breast disease, and it can even predict the malignancy degree of breast cancer, as well as its invasive ability and prognosis.

To evaluate the feasibility of an intervention designed to promote sleep and modify fatigue during four cycles of adjuvant breast cancer chemotherapy. Prospective, repeated measures, quasi-experimental feasibility study. Midwestern urban oncology clinics. 25 women between the ages of 40-65 (mean = 54.3) with stage I-II breast cancer receiving doxorubicin-based chemotherapy. Each woman developed, reinforced, and revised an individualized sleep promotion plan (ISPP) with four components: sleep hygiene, relaxation therapy, stimulus control, and sleep restriction techniques. A daily diary, the Pittsburgh Sleep Quality Index, a wrist actigraph, and the Piper Fatigue Scale were used to collect data two days before and seven days after each treatment. Adherence, sleep and wake outcomes, and fatigue. Adherence rates with the components of the ISPP varied during treatments one through four: sleep hygiene (68%-78%), relaxation therapy (57%-67%), stimulus control (46%-67%), and sleep restriction (76%-80%). Mean sleep and wake outcomes at baseline, peak, and rebound times were that (a) sleep latency remained brief (less than 30 minutes per night), (b) time awake after sleep onset exceeded the desired less than 30 minutes per night, (c) sleep efficiency scores remained stable at 85%-90%, (d) total rest time remained stable at 8-10 hours per night, (e) subjective ratings of feelings on arising were stable, and (f) nighttime awakenings were 8-10 per night. Fatigue outcomes were that fatigue was stable two days after each treatment and mean daily fatigue intensity was lower at treatment three than at treatment one but rebounded at treatment four. The intervention was feasible, adherence rates improved over time, and most sleep and wake patterns were consistent with normal values. Revisions will focus on decreasing nighttime awakenings. Adopting behaviors to promote sleep may assist in maintaining sleep and managing fatigue during chemotherapy.

Ethnic and socioeconomic inequities in use of breast cancer adjuvant therapy are well documented in many countries including the USA, and are known to contribute to lower breast cancer survival among minority ethnic and socioeconomically deprived women. We investigated ethnic and socioeconomic inequities in use of adjuvant radiotherapy and chemotherapy in a cohort of women with invasive breast cancer in New Zealand. All women with newly diagnosed invasive breast cancer during 1999-2012 were identified from the Waikato Breast Cancer Register. Rates of chemotherapy use and radiotherapy use were assessed in women who were deemed to be eligible for chemotherapy (n = 1212) and radiotherapy (n = 1708) based on guidelines. Factors associated with use of chemotherapy and radiation therapy were analysed in univariate and multivariate regression models, adjusting for covariates. Overall, rates of chemotherapy and radiotherapy use were 69% (n = 836) and 87.3% (n = 1491), respectively. In the multivariate model, significantly lower rates of radiotherapy use were associated with Māori compared with NZ European (Odds Ratio [OR] = 0.63, 0.40-0.98), presence of comorbidity (OR = 0.49, 0.34-0.72), distance from hospital of over 100km (OR = 0.47, 0.23-0.96), mastectomy compared with breast conserving surgery (OR = 0.32, 0.17-0.56) and non-screen compared with screen detection (OR = 0.53, 0.35-0.79). No significant associations were observed between chemotherapy use and ethnic or socio-demographic factors. Improving access for radiotherapy, especially for women who are at a higher risk of not receiving optimum cancer therapy due to ethnicity, geography or socioeconomic status need to be recognized as a priority to reduce inequities in breast cancer care in New Zealand.

Magnetic nanoparticle hyperthermia as an adjuvant cancer therapy with chemotherapy

NASA Astrophysics Data System (ADS)

Petryk, Alicia Ailie

Magnetic nanoparticle hyperthermia (mNPH) is an emerging cancer therapy which has shown to be most effective when applied in the adjuvant setting with chemotherapy, radiation or surgery. Although mNPH employs heat as a primary therapeutic modality, conventional heat may not be the only cytotoxic effect. As such, my studies have focused on the mechanism and use of mNPH alone and in conjunction with cisplatinum chemotherapy in murine breast cancer cells and a related in vivo model. MNPH was compared to conventional microwave tumor heating, with results suggesting that mNPH (mNP directly injected into the tumor and immediately activated) and 915 MHz microwave hyperthermia, at the same thermal dose, result in similar tumor regrowth delay kinetics. However, mNPH shows significantly less peri-tumor normal tissue damage. MNPH combined with cisplatinum also demonstrated significant improvements in regrowth delay over either modality applied as a monotherapy. Additional studies demonstrated that a relatively short tumor incubation time prior to AMF exposure (less than 10 minutes) as compared to a 4-hour incubation time, resulted in faster heating rates, but similar regrowth delays when treated to the same thermal dose. The reduction of heating rate correlated well with the observed reduction in mNP concentration in the tumor observed with 4 hour incubation. The ability to effectively deliver cytotoxic mNPs to metastatic tumors is the hope and goal of systemic mNP therapy. However, delivering relevant levels of mNP is proving to be a formidable challenge. To address this issue, I assessed the ability of cisplatinum to simultaneously treat a tumor and improve the uptake of systemically delivered mNPs. Following a cisplatinum pretreatment, systemic mNPs uptake was increased by 3.1 X, in implanted murine breast tumors. Additional in vitro studies showed the necessity of a specific mNP/ Fe architecture and spatial relation for heat-based cytotoxicity in cultured cells.

Background The aim of the present study was to investigate the efficacy of adjuvant dose-dense sequential chemotherapy with epirubicin, paclitaxel, and CMF in subgroups of patients with high-risk operable breast cancer, according to tumor subtypes defined by immunohistochemistry (IHC). Materials and Methods Formalin-fixed paraffin-embedded (FFPE) tumor tissue samples from 1,039 patients participating in two adjuvant dose-dense sequential chemotherapy phase III trials were centrally assessed in tissue micro-arrays by IHC for 6 biological markers, that is, estrogen receptor (ER), progesterone receptor (PgR), HER2, Ki67, cytokeratin 5 (CK5), and EGFR. The majority of the cases were further evaluated for HER2 amplification by FISH. Patients were classified as: luminal A (ER/PgR-positive, HER2-negative, Ki67low); luminal B (ER/PgR-positive, HER2-negative, Ki67high); luminal-HER2 (ER/PgR-positive, HER2-positive); HER2-enriched (ER-negative, PgR-negative, HER2-positive); triple-negative (TNBC) (ER-negative, PgR-negative, HER2-negative); and basal core phenotype (BCP) (TNBC, CK5-positive and/or EGFR-positive). Results After a median follow-up time of 105.4 months the 5-year disease-free survival (DFS) and overall survival (OS) rates were 73.1% and 86.1%, respectively. Among patients with HER2-enriched tumors there was a significant benefit in both DFS and OS (log-rank test; p = 0.021 and p = 0.006, respectively) for those treated with paclitaxel. The subtype classification was found to be of both predictive and prognostic value. Setting luminal A as the referent category, the adjusted for prognostic factors HR for relapse for patients with TNBC was 1.91 (95% CI: 1.31–2.80, Wald's p = 0.001) and for death 2.53 (95% CI: 1.62–3.60, p<0.001). Site of and time to first relapse differed according to subtype. Locoregional relapses and brain metastases were more frequent in patients with TNBC, while liver metastases were more often seen in patients with HER2

Characteristics that predispose patients to financial hardship during cancer treatment are poorly understood. We therefore conducted a population-based exploratory analysis of potential factors associated with financial hardship and treatment nonadherence during and following adjuvant chemotherapy for colon cancer. Patients diagnosed with stage III colon cancer between 2008 and 2010 were identified from a population-based cancer registry representing 13 counties in Washington state. Patients were asked to complete a comprehensive survey on treatment-related costs. Patients were considered to have experienced financial hardship if they accrued debt, sold or refinanced their home, borrowed money from friends or family, or experienced a 20% or greater decline in their annual income as a result of treatment-related expenses. Logistic regression analysis was used to investigate factors associated with financial hardship and treatment nonadherence. A total of 284 responses were obtained from 555 eligible patients (response rate, 51.2%). Nearly all patients in the final sample were insured during treatment. In this sample, 38% of patients reported one or more financial hardships as a result of treatment. The factors most closely associated with treatment-related financial hardship were younger age and lower annual household income. Younger age, lower income, and unemployment or disability (which occurred in most instances following diagnosis) were most closely associated with treatment nonadherence. A significant proportion of patients undergoing adjuvant chemotherapy for stage III colon cancer may experience financial hardship, despite having health insurance coverage. Interventions to help at-risk patients early on during therapy may prevent long-term financial adverse effects.

The management of stage I seminoma has evolved over the past 20 years. Contemporary management options after orchiectomy include adjuvant radiation, adjuvant chemotherapy, and observation. This analysis defines the experience at Kaiser Permanente Southern California from 1990 to 2010. We examined outcomes for stage I seminoma patients and reviewed prognostic factors for recurrence in those managed with observation. This is a retrospective study of 502 stage I seminoma patients who underwent orchiectomy from 1990 to 2010. Outcomes examined were relapse-free survival (RFS), overall survival (OS), and cause-specific survival (CSS). Risk factors for recurrence evaluated were age, preoperative hCG elevation, preoperative LDH elevation, tumor size, lymphovascular invasion, rete testis invasion, epididymis invasion, and invasion through the tunica albuginea. Among radiation patients, 5-year RFS was 97.2%, OS was 98.0%, and CSS was 99.3%. Among chemotherapy patients, 2-year RFS was 98.3% and OS and CSS were 100%. Among observation patients, 5-year RFS was 89.2%, OS was 98.8%, and CSS was 100%. There was no difference in OS or CSS among the groups. RFS was significantly lower for observation patients. Among observation patients, univariate analysis identified tumor size, lymphovascular invasion, and rete testis invasion as risk factors for relapse. No factors were significant on multivariate analysis. Our data show that adjuvant radiation and chemotherapy yield similar outcomes in the management of stage I seminoma. Observation results in a lower RFS, but patients who relapse can be salvaged; OS and CSS are not affected.

Current standard treatment for patients with cervical cancer who have locally advanced stage disease (International Federation of Gynecology and Obstetrics (FIGO) stage IIB to IVA) is concurrent chemoradiation therapy (CCRT). However, less than two-thirds of patients in this group survive for longer than five years post treatment. Adjuvant chemotherapy (ACT) can be given in an attempt to improve survival by eradicating residual disease in the pelvis and treating occult disease outside the pelvic radiation field. However, inconsistency in trial design, inclusion criteria for participants, interventions and survival benefit has been noted among trials of ACT after CCRT for locally advanced cervical cancer (LACC). To evaluate the effect of adjuvant chemotherapy (ACT) after concurrent chemoradiation (CCRT) on survival of women with locally advanced cervical cancer compared with CCRT alone. We searched the Cochrane Gynaecological Review Group Trial Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and conference proceedings to March 2014. We handsearched citation lists of relevant studies. Randomised controlled trials (RCTs) comparing CCRT alone versus CCRT plus ACT were included. Patients were diagnosed with cervical cancer FIGO stage IIB to IVA with a histopathology of squamous cell carcinoma, adenosquamous cell carcinoma, adenocarcinoma or undifferentiated carcinoma. Two review authors (ST, KK) selected relevant trials, extracted data, assessed risk of bias independently, compared results and resolved disagreements by discussion. We identified two RCTs involving 978 women with cervical cancer stage IIB to IVA. As the trials were significantly different clinically, we did not perform meta-analyses. One industry-funded trial involving 515 women compared CCRT (cisplatin) versus CCRT (cisplatin and gemcitabine) plus ACT (two additional cycles). This trial reported significant improvement in progression-free survival (PFS) and overall

Current guidelines recommend adjuvant chemotherapy for resected pancreatic adenocarcinoma (PDAC). However, no studies have addressed its survival benefit for stage I patients as they comprise <10% of PDAC. Using the NCDB 2006-2012, resected PDAC patients with stage I disease who received adjuvant therapy (chemotherapy or chemoradiation) were analyzed. Factors associated with overall survival (OS) were identified. 3909 patients with resected stage IA or IB PDAC were identified. Median OS was 60.3 months (mo) for stage IA and 36.9 mo for IB. 45.5% received adjuvant chemotherapy; 19.9% received adjuvant chemoradiation. There was OS benefit for both stage IA/IB patients with adjuvant chemotherapy (HR = 0.73 and 0.76 for IA and IB, respectively, p = 0.002 and <0.001). For patients with Stage IA disease (n = 1,477, 37.8%), age ≥70 (p < 0.001), higher grade (p < 0.001), ≤10 lymph nodes examined (p = 0.008), positive margins (p < 0.001), and receipt of adjuvant chemoradiation (p = 0.002) were associated with worse OS. For stage IB patients (n = 2,432, 62.2%), similar associations were observed with the exception of adjuvant chemoradiation whereby there was no significant association (p = 0.35). Adjuvant chemotherapy was associated with an OS benefit for patients with stage I PDAC; adjuvant chemoradiation was either of no benefit or associated with worse OS.

To explore the relationship of regional cerebral blood flow and metabolism with cognitive function and past exposure to chemotherapy for breast cancer. Subjects treated for breast cancer with adjuvant chemotherapy remotely (5-10 years previously) were studied with neuropsychologic testing and positron emission tomography (PET), and were compared with control subjects who had never received chemotherapy. [O-15] water PET scans was acquired during performance of control and memory-related tasks to evaluate cognition-related cerebral blood flow, and [F-18] fluorodeoxyglucose (FDG) PET scans were acquired to evaluate resting cerebral metabolism. PET scans were analyzed by statistical parametric mapping and region of interest methods of analysis. During performance of a short-term recall task, modulation of cerebral blood flow in specific regions of frontal cortex and cerebellum was significantly altered in chemotherapy-treated subjects. Cerebral activation in chemotherapy-treated subjects differed most significantly from untreated subjects in inferior frontal gyrus, and resting metabolism in this area correlated with performance on a short-term memory task previously found to be particularly impaired in chemotherapy-treated subjects. In examining drug-class specific effects, metabolism of the basal ganglia was significantly decreased in tamoxifen + chemotherapy-treated patients compared with chemotherapy-only breast cancer subjects or with subjects who had not received chemotherapy, while chemotherapy alone was not associated with decreased basal ganglia activity relative to untreated subjects. Specific alterations in activity of frontal cortex, cerebellum, and basal ganglia in breast cancer survivors were documented by functional neuroimaging 5-10 years after completion of chemotherapy.

Purpose: To analyze the recent single-institution experience of patients with salivary gland tumors who had undergone adjuvant intensity-modulated radiotherapy (IMRT), with or without concurrent chemotherapy. Patients and Methods: We performed a retrospective analysis of 35 salivary gland carcinoma patients treated primarily at the Dana-Farber Cancer Institute between 2005 and 2010 with surgery and adjuvant IMRT. The primary endpoints were local control, progression-free survival, and overall survival. The secondary endpoints were acute and chronic toxicity. The median follow-up was 2.3 years (interquartile range, 1.2-2.8) among the surviving patients. Results: The histologic types included adenoid cystic carcinoma in 15 (43%), mucoepidermoid carcinomamore » in 6 (17%), adenocarcinoma in 3 (9%), acinic cell carcinoma in 3 (9%), and other in 8 (23%). The primary sites were the parotid gland in 17 (49%), submandibular glands in 6 (17%), tongue in 4 (11%), palate in 4 (11%), and other in 4 (11%). The median radiation dose was 66 Gy, and 22 patients (63%) received CRT. The most common chemotherapy regimen was carboplatin and paclitaxel (n = 14, 64%). A trend was seen for patients undergoing CRT to have more adverse prognostic factors, including Stage T3-T4 disease (CRT, n = 12, 55% vs. n = 4, 31%, p = .29), nodal positivity (CRT, n = 8, 36% vs. n = 1, 8%, p = .10), and positive margins (n = 13, 59% vs. n = 5, 38%, p = .30). One patient who had undergone CRT developed an in-field recurrence, resulting in an overall actuarial 3-year local control rate of 92%. Five patients (14%) developed distant metastases (1 who had undergone IMRT only and 4 who had undergone CRT). Acute Grade 3 mucositis, esophagitis, and dermatitis occurred in 8%, 8%, and 8% (1 each) of IMRT patients and in 18%, 5%, and 14% (4, 1, and 3 patients) of the CRT group, respectively. No acute Grade 4 toxicity occurred. The most common late toxicity was Grade 1 xerostomia (n = 8, 23%). Conclusions

Oxaliplatin-based adjuvant chemotherapy has been the standard of care for resected early colon cancer for over a decade. Recent results from the IDEA meta-analysis attempt to address the question of whether 3 or 6 months of adjuvant chemotherapy is preferable in Stage III colon cancer. Areas covered: A review of the literature and recent conference presentations was undertaken on the topic of adjuvant therapy for resected early colon cancers. This article reviews the current evidence for adjuvant treatment of Stage II and III colon cancer, as well as up-to-date data regarding optimal duration of therapy. This article reviews the evidence for lifestyle modifications in the management of early colorectal cancer and other future directions for research in early colon cancer. Expert commentary: In recent years, there have been no advances in the development of novel agents for adjuvant therapy in colorectal cancer. Although the IDEA meta-analysis was negative for its primary non-inferiority endpoint, the detailed results provide valuable information that allows personalisation of treatment regimen and duration.

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

PubMed

Gadgeel, Shirish M

2017-01-01

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

While 5-year survival rates in patients with stage IB non-small-cell lung cancer (NSCLC) are historically modest (40% to 67%), adjuvant chemotherapy trials including this subgroup have shown little evidence of chemotherapeutic benefit. This article reviews the available data regarding adjuvant chemotherapy following surgically resected stage IB NSCLC, framed within the context of present and future proposed definitions of this diagnosis. The discussion addresses limitations of the current staging system and how this contributes to the mixed results seen with adjuvant treatment. In addition, the authors consider current treatment options for stage IB NSCLC and review planned clinical trials for stage I disease designed to exploit new pharmacogenomic findings.

The optimal postoperative treatment strategy for small cell lung cancer (SCLC) remains unclear, especially in patients with lymph node metastasis. We aimed to compare the outcomes of patients with SCLC and lymph node metastasis treated with postoperative adjuvant chemotherapy or chemoradiotherapy. We retrospectively collected data on patients with postoperative SCLC diagnosed with N1 and N2 lymph node metastasis from the Diagnosis Procedure Combination database in Japan, between July 2010 and March 2015. We extracted data on patient age, sex, comorbidities, and TNM classification at lung surgery; operative procedures, chemotherapy drugs, and radiotherapy during hospitalization; and discharge status. Recurrence-free survival was compared between the chemotherapy and chemoradiotherapy groups using multivariable Cox regression analysis. Median recurrence-free survival was 1146 days (95% confidence interval [CI], 885-1407) in the chemotherapy group (n = 489) and 873 days (95% CI, 464-1282) in the chemoradiotherapy group (n = 75). There was no significant difference between these after adjusting for patient backgrounds (hazard ratio, 1.29; 95% CI, 0.91-1.84). There was no significant difference in recurrence-free survival between patients with SCLC and N1-2 lymph node metastasis treated with postoperative adjuvant chemotherapy and chemoradiotherapy. Further randomized clinical trials are needed to address this issue.

A prognostic test was developed to guide adjuvant chemotherapy (ACT) decisions in early-stage non-small cell lung cancer (NSCLC) adenocarcinomas. The objective of this study was to compare the cost-utility of the prognostic test to the current standard of care (SoC) in patients with early-stage NSCLC. Lifetime costs (2014 U.S. dollars) and effectiveness (quality-adjusted life-years [QALYs]) of ACT treatment decisions were examined using a Markov microsimulation model from a U.S. third-party payer perspective. Cancer stage distribution and probability of receiving ACT with the SoC were based on data from an academic cancer center. The probability of receiving ACT with the prognostic test was estimated from a physician survey. Risk classification was based on the 5-year predicted NSCLC-related mortality. Treatment benefit with ACT was based on the prognostic score. Discounting at a 3% annual rate was applied to costs and QALYs. Deterministic one-way and probabilistic sensitivity analyses examined parameter uncertainty. Lifetime costs and effectiveness were $137,403 and 5.45 QALYs with the prognostic test and $127,359 and 5.17 QALYs with the SoC. The resulting incremental cost-effectiveness ratio for the prognostic test versus the SoC was $35,867/QALY gained. One-way sensitivity analyses indicated the model was most sensitive to the utility of patients without recurrence after ACT and the ACT treatment benefit. Probabilistic sensitivity analysis indicated the prognostic test was cost-effective in 65.5% of simulations at a willingness to pay of $50,000/QALY. The study suggests using a prognostic test to guide ACT decisions in early-stage NSCLC is potentially cost-effective compared with using the SoC based on globally accepted willingness-to-pay thresholds. Providing prognostic information to decision makers may help some patients with high-risk early stage non-small cell lung cancer receive appropriate adjuvant chemotherapy while avoiding the associated toxicities and

Preventing distant recurrence and achieving local control are important challenges in rectal cancer treatment, and use of adjuvant chemotherapy has been studied. However, no phase III study comparing adjuvant chemotherapy regimens for rectal cancer has demonstrated superiority of a specific regimen. We therefore conducted a phase III study to evaluate the superiority of S-1 to tegafur-uracil (UFT), a standard adjuvant chemotherapy regimen for curatively resected stage II/III rectal cancer in Japan, in the adjuvant setting for rectal cancer. The ACTS-RC trial was an open-label, randomized, phase III superiority trial conducted at 222 sites in Japan. Patients aged 20-80 with stage II/III rectal cancer undergoing curative surgery without preoperative therapy were randomly assigned to receive UFT (500-600 mg/day on days 1-5, followed by 2 days rest) or S-1 (80-120 mg/day on days 1-28, followed by 14 days rest) for 1 year. The primary end point was relapse-free survival (RFS), and the secondary end points were overall survival and adverse events. In total, 961 patients were enrolled from April 2006 to March 2009. The primary analysis was conducted in 480 assigned to receive UFT and 479 assigned to receive S-1. Five-year RFS was 61.7% [95% confidence interval (CI) 57.1% to 65.9%] for UFT and 66.4% (95% CI 61.9% to 70.5%) for S-1 [P = 0.0165, hazard ratio (HR): 0.77, 95% CI 0.63-0.96]. Five-year survival was 80.2% (95% CI 76.3% to 83.5%) for UFT and 82.0% (95% CI 78.3% to 85.2%) for S-1. The main grade 3 or higher adverse events were increased alanine aminotransferase and diarrhea (each 2.3%) in the UFT arm and anorexia, diarrhea (each 2.6%), and fatigue (2.1%) in the S-1 arm. One-year S-1 treatment is superior to UFT with respect to RFS and has therefore become a standard adjuvant chemotherapy regimen for stage II/III rectal cancer following curative resection. © The Author 2016.

Growing evidence shows tumor-infiltrating neutrophils (TINs) involvement in tumorigenesis. The objective of this study is to assess the prognostic effect of TINs and its impact on adjuvant chemotherapy benefits in muscle invasive bladder cancer (MIBC). A total of 142 MIBC patients from Zhongshan Hospital, 119 MIBC patients from FUSCC, and 405 MIBC patients from TCGA cohort were enrolled in the study. TINs were evaluated by immunohistochemical staining of CD66b or the CIBERSORT method. Patients with high TINs had a significantly poorer overall survival ( p = 0.001, p < 0.001, and p = 0.002, respectively) in the three sets. In the multivariate analysis, the presence of high TINs (HR = 2.122, p = 0.007; HR = 3.807, p < 0.001; HR = 2.104, p = 0.001; respectively) was identified as an independent prognostic factor for overall survival in the three sets. More importantly, Low TINs patients had significantly longer overall survival in patients without ACT in the three sets. Gene set enrichment analysis showed that lymphocyte activation ( p < 0.001) and T cell activation ( p = 0.008) were significantly enriched in the low TINs group. In addition, TINs were negatively correlated with CD8 + T cells, suggesting that the status of high-TINs was linked to the status of immunosuppression in MIBC. TINs could be used as independent prognostic factor. Low TINs identified a subgroup of MIBC patients who appeared to benefit from adjuvant chemotherapy. Incorporation of TINs into TNM system could further stratify patients with different prognosis.

To conduct an exploratory analysis of the relationship between gene expression and recurrence in patients with operable triple-negative breast cancer (TNBC) treated with adjuvant doxorubicin-containing chemotherapy. RNA was extracted from archived tumor samples derived from 246 patients with stage I-III TNBC treated with adjuvant doxorubicin-containing chemotherapy, and was analyzed by quantitative reverse transcriptase PCR for a panel of 374 genes. The relationship between gene expression and recurrence was evaluated using weighted Cox proportional hazards model score tests. Growth factor receptor bound protein 7 (GRB7) was the only gene for which higher expression was significantly associated with increased recurrence in TNBC (Korn's adjusted P value = 0.04). In a Cox proportional hazards model adjusted for clinicopathologic features, higher GRB7 expression was associated with an increased recurrence risk (HR = 2.31; P = 0.04 using the median as the split). The 5-year recurrence rates were 10.5% [95% confidence intervals (CI), 7.8-14.1] in the low and 20.4% (95% CI, 16.5-25.0) in the high GRB7 groups. External validation in other datasets indicated that GRB7 expression was not prognostic in two adjuvant trials including variable systemic therapy, but in two other trials showed that high GBR7 expression was associated with resistance to neoadjuvant doxorubicin and taxane therapy. GRB7 was associated with an increased risk of recurrence in TNBC, suggesting that GRB7 or GRB7-dependent pathways may serve as potential biomarkers for therapeutic targets. Therapeutic targeting of one or more factors identified which function as interaction nodes or effectors should also be considered.

Based on estrogen receptor (ER) status and menopausal status, operable breast cancer (International Union Against Cancer [UICC] Stage I, II, and III) patients were randomized for adjuvant endocrine therapy, chemotherapy, and chemoendocrine therapy, and the effects on the disease-free survival (DFS) and overall survival (OS) were compared. Adjuvant endocrine therapy was composed of tamoxifen (TAM) 20 mg/day orally for 2 years in postmenopausal patients. In premenopausal patients, oophorectomy (OVEX) was done before TAM administration. In the chemotherapy arm, the patients were given 0.06 mg/kg of body weight of mitomycin C (MMC) intravenously (IV) and then an oral administration of cyclophosphamide (CPA) 100 mg/body orally in an administration of a 3-month period and a 3-month intermission. This 6-month schedule was repeated four times in 2 years. As the chemoendocrine therapy arm, TAM with MMC + CPA chemotherapy was added. The patients were randomized according to ER and menopausal status. Estrogen receptor-positive (ER+) cancer patients were randomized to three arms: TAM +/- OVEX, MMC + CPA, or MMC + CPA + TAM. For estrogen receptor-negative (ER-) patients, there were two arms: MMC + CPA, or MMC + TAM. The study started in September 1978, and 692 patients entered until the end of 1984 were evaluated. The median follow-up was about 46 months. Totally, a 9.8% rate (68/692) of recurrence was noted, a 7.5% rate (52/692) of mortality. There were no significant differences in DFS or OS among the treatment arms in ER+ or ER- patients. There was significant differences in adverse effects such as bone marrow suppression, gastrointestinal disturbances, cystitis, hair loss between endocrine therapy and chemotherapy or chemoendocrine therapy groups. In this preliminary study, it was concluded that because of less adverse effects of endocrine therapy, it seems rational to select the operable breast cancer patients by the presence or absence of ER, namely, endocrine therapy for

Recent studies demonstrated the efficacy of S-1-based adjuvant chemotherapy administered for six months after curative surgery for stage III gastric cancer; however, it is unproven whether this type of combination chemotherapy is more effective than the standard adjuvant chemotherapy of S-1 for one year. This multicenter phase II study evaluate the efficacy and safety of adjuvant chemotherapy using S-1 plus oxaliplatin followed by S-1 for up to one year for curatively resected stage III gastric cancer in patients aged over 20 years. Treatment initially comprises oral fluoropyrimidine S-1 (80 mg/m 2 ) administered twice daily for the first 2 weeks of a 3-week cycle. On day 1 of a second 3-week cycle, patients will receive 100 mg/m 2 of intravenous oxaliplatin followed by 80 mg/m 2 of S-1 (maximum 8 cycles). Then, the patients will receive 80 mg/m 2 of S-1 daily for 4 weeks, followed by 2 weeks of no chemotherapy. This 6-week cycle will be repeated during the first year after surgery. The primary endpoint is relapse-free survival for 3 years and secondary endpoints are safety, including the incidence of adverse events, and grading of neuropathy with each treatment cycle. The planned sample size of 75 patients is appropriate for this trial. The data will be analyzed on an intention-to-treat basis, assuming a two-sided test with a 5% level of significance. In contrast to previous trials, the current study involves administration of S-1 until one year after surgery in addition to prior S-1 plus oxaliplatin, and is the first study to evaluate the safety and efficacy of S-1 plus oxaliplatin followed by S-1 for up to one year in patients with curatively resected stage III gastric cancer. This trial is registered in the University Hospital Medical Information Network's Clinical Trials Registry (UMIN-CTR) registration number, R000029656  ( https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000029656 ).

quality of life and cognitive function are experienced by women with breast cancer who are receiving adjuvant chemotherapy. These decrements can be identified in some women even several years following treatment. The majority of relevant research has been based on retrospective data in women with breast cancer. Current estimates suggest that 25% of breast cancers will be diagnosed in women under age 50, yet very little data are available regarding younger women’s cognitive function and quality of life during chemotherapy.

Despite advances in adjuvant chemotherapy, 20-30% of patients in stages II-III colorectal cancer will eventually relapse. Observational studies showed a reduction in relapse rate, colon cancer-specific mortality, and overall mortality by physical activity. Results from prospective randomized interventional studies to confirm these observational data are lacking. The aims of this prospective single-arm multicenter pilot study are to evaluate feasibility and safety of exercise training after adjuvant chemotherapy in colorectal cancer patients. The training was performed three times per week for 1 year and was increased gradually in three phases until reaching 18 metabolic equivalent task hours per week. Overall, 30 patients were included. The planned training intensity could be achieved in all three phases. Patients experienced a performance increase of median 35.5 watt, a weight-loss of a median of 3.0 kg, and a reduction in body fat content of median 1.0% during this exercise training. The analysis showed early study termination due to non-compliance in 10/30 patients (33.3%), disease progression in 4 patients (13.3%), and serious adverse events in 2 patients (6.7%). About half of patients (46.7%) completed the pilot study as planned. Biomarker analysis from 20 patients showed a non-significant reduction in insulin-like growth factor 1 (IGF-1), insulin-like growth factor 2 (IGF-2) and insulin-like growth factor binding protein 3 (IGF-BP3) levels, significant increases in adiponectin and leptin levels, and a non-significant increase in C-peptide levels. Exercise training is feasible in patients with colorectal cancer after completion of adjuvant chemotherapy. The main problem encountered during the study was compliance. To improve compliance of exercise training, several measures were adapted for the upcoming prospective randomized ABCSG C08 Exercise II study.

This multicenter study evaluated the feasibility of novel adjuvant chemotherapy with S-1 plus carboplatin followed by single-agent, long-term maintenance with S-1 in patients with completely resected stage II-IIIA non-small-cell lung cancer (NSCLC). Patients received four cycles of S-1 (80 mg/m 2 /day for 2 weeks, followed by 2 weeks rest) plus carboplatin (area under the curve 5, day 1) followed by S-1 (80 mg/m 2 /day for 2 weeks, followed by a 1-week rest). Patients unable to continue S-1 plus carboplatin because of severe toxicity converted to single-agent S-1 maintenance. The duration of adjuvant chemotherapy was 10 months in both situations. The primary endpoint was feasibility, defined as the proportion of patients who completed four cycles of S-1 plus carboplatin and single-agent S-1 maintenance for 10 months. The treatment completion rate was determined; treatment was considered feasible if the lower 90% confidence interval (CI) was ≥50%. Eighty-nine patients were enrolled, of whom 87 were eligible and assessable. Seventy-eight patients (89.7%) completed four cycles of S-1 plus carboplatin and 55 (63.2%) completed the following S-1 maintenance therapy for a total of 10 months. The treatment completion rate was 63.2% (90% CI, 54.4-71.2%), indicating feasibility. There were no treatment-related deaths. Grade 3/4 toxicities included neutropenia (13.8%), thrombocytopenia (11.5%), and anorexia (4.6%). The 2-year relapse-free survival rate was 59.8%. We concluded that adjuvant chemotherapy with S-1 plus carboplatin followed by single-agent maintenance therapy with S-1 is feasible and tolerable in patients with completely resected NSCLC.

BACKGROUND With advances in oncologic treatment, cosmesis after mastectomy has assumed a pivotal role in patient and provider decision making. Multiple studies have confirmed the safety of both chemotherapy before breast surgery and immediate reconstruction. Little has been written about the effect of neoadjuvant chemotherapy on decisions about reconstruction. METHODS The authors identified 665 patients with stage I through III breast cancer who received chemotherapy and underwent mastectomy at Dana-Farber/Brigham & Women’s Cancer Center from 1997 to 2007. By using multivariate logistic regression, reconstruction rates were compared between patients who received neoadjuvant chemotherapy (n = 180) and patients who underwent mastectomy before chemotherapy (n = 485). The rate of postoperative complications after mastectomy was determined for patients who received neoadjuvant chemotherapy compared with those who did not. RESULTS Reconstruction was performed immediately in 44% of patients who did not receive neoadjuvant chemotherapy but in only 23% of those who did. Twenty-one percent of neoadjuvant chemotherapy recipients and 14% of adjuvant-only chemotherapy recipients underwent delayed reconstruction. After controlling for age, receipt of radiotherapy, and disease stage, neoadjuvant recipients were less likely to undergo immediate reconstruction (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.37, 0.87) but were no more likely to undergo delayed reconstruction (OR, 1.29; 95% CI, 0.75, 2.20). Surgical complications occurred in 30% of neoadjuvant chemotherapy recipients and in 31% of adjuvant chemotherapy recipients. CONCLUSIONS The current results suggest that patients who receive neoadjuvant chemotherapy are less likely to undergo immediate reconstruction and are no more likely to undergo delayed reconstruction than patients who undergo surgery before they receive chemotherapy.

PURPOSE: To perform an exploratory analysis of the relationship between gene expression and recurrence in operable hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-normal breast cancer patients treated with adjuvant doxorubicin-containing chemotherapy. EXPERIMENTAL DESIGN: RNA was extracted from archived tumor samples derived from 378 patients with stage I to III HR-positive, HER2-normal breast cancer and analyzed by reverse transcription-PCR for a panel of 374 genes, including the 21-gene recurrence score (RS). Patients were randomized to receive adjuvant doxorubicin plus cyclophosphamide or docetaxel in trial E2197, with no difference in recurrence seen in the treatment arms. All available recurrent cases were selected plus a nonrecurrent cohort. Cox proportional hazard models were used to identify relationships between gene expression and recurrence. RESULTS: TOP2A expression exhibited the strongest association with increased recurrence risk (P = 0.01), and was significantly associated with recurrence (P = 0.008) in a multivariate analysis adjusted for clinicopathologic features. Elevated TOP2A expression above the median was associated with a 2.6-fold increase (95% confidence interval, 1.3-5.2; P = 0.008) in risk of recurrence if the RS was <18, and a 2.0-fold increase (95% confidence interval, 1.2-3.2, P = 0.003) if there was an intermediate RS of 18 to 30. CONCLUSIONS: In patients with HR-positive, HER2-normal breast cancer, a population known to have a low incidence of TOP2A gene alterations thought to be predictive of anthracycline benefit, there is a range of TOP2A RNA expression that is strongly associated with recurrence after adjuvant anthracyclines, which provides information complementary to RS, indicating that it merits further evaluation as a prognostic and predictive marker.

Triple negative breast cancer (TNBC) is immunohistochemically characterised by the lack of expression of the estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor type 2 (HER2). TNBC is known for its poor prognosis and high recurrence probability. There is no effective targeted treatment for TNBC, but only adjuvant chemotherapies. There are two TNBC subtypes, basal-like and non-basal-like, which are defined based on positive cytokeratin (CK) 5/6 and/or epidermal growth factor receptor (EGFR) expression. In particular, CK5/6 expression is reported to correlate with TNBC recurrence. TNBC lacks ER-α expression, but some TNBCs are known to express the androgen receptor (AR). Moreover, although p53 accumulation is detected in various malignant tumors, its influence on adjuvant chemotherapy for patients with TNBC remains unclear. The aim of this study was to assess the combined immunohistochemical expression of CK 5/6, AR, and p53 as a potential prognostic marker of adjuvant chemotherapy for patients with TNBC. The expression of CK5/6, AR, and p53 in formalin-fixed and paraffin-embedded (FFPE) surgical sections from 52 patients with TNBC was analysed by immunohistochemistry (IHC) and the co-expression patterns in individual cells were investigated by immunofluorescent (IF) staining. Low AR expression was correlated with high clinical stage (P < 0.05) and low nuclear grade (P < 0.05). The expression of CK5/6 and p53 did not correlate with clinicopathological features. Patients who needed adjuvant chemotherapy presented the worst prognosis. In particular, when the IHC expression pattern was CK5/6 (-), AR (-), and p53 (+), the disease free survival (DFS) and overall survival (OS) were the worst. On the other hand, patients with AR (+) and p53 (-) TNBC presented a good prognosis. The analysis of the co-expression status of these three markers showed that no cells presented both AR and CK5/6 expression. Furthermore, TP53 m

The objective of this study was to demonstrate the feasibility and efficacy of induction chemotherapy, surgery, and pathology-guided adjuvant therapy to treat transorally resectable squamous head and neck cancer. Patients had squamous head and neck cancer that was resectable by the transoral route and advanced-stage disease (American Joint Committee on Cancer stage III-IV, T3-T4 tumors, and/or positive lymph nodes). They received treatment with weekly carboplatin at an area under the curve of 2, plus paclitaxel 135 mg/m 2 , and daily lapatinib 1000mg for 6 weeks followed by surgical resection. Pathology that revealed margins <5 mm, extracapsular extension, N2a of N2b lymph node status, perineural invasion, or lymphovascular space invasion resulted in adjuvant radiotherapy concurrent with weekly cisplatin. Pathology with N2c/N3 lymph node status or positive margins resulted in radiation with bolus cisplatin. The primary endpoint was the clinical response rate to induction chemotherapy, and a key secondary endpoint was feasibility. Toxicity was modest, and 37 of 40 patients completed study procedures as planned. The clinical response rate was 93%, the pathologic complete response rate was 36%, and the clinical response did not predict for a pathologic complete response. No patient on study follow-up has recurred or died. Twenty-nine of 39 patients who underwent surgery avoided radiation. Speech and swallowing function were well preserved. The study met both its primary efficacy endpoint and the secondary feasibility endpoint. Neoadjuvant, systemic therapy and surgical resection followed by risk-adapted adjuvant therapy resulted in high response rates and excellent long-term outcomes and should be further studied.

Patients were divided into 2 groups according to regimen; the groups were XELOX (n = 114) and S-1 monotherapy (n = 92). 3-year disease-free survival (DFS) was higher in the S-1 group than in the XELOX group (66.6% vs 59.1%; p = 0.636). 3-year overall survival (OS) was 75.6% in the S-1 group and 69.6% in the XELOX group (p = 0.495). But, the difference was not statistically significant. Especially, for patients with stage IIIC disease, 3-year overall survival was 55.2% in the XELOX group and 39.0% in the S-1 group (hazard ratio, HR 0.50, 95% confidence interval, CI 0.23-1.10; p = 0.075). In multivariate analysis, N stage (HR, 5.639; 95% CI, 1.297-24.522; p = 0.021) and cycle completion as planned (HR, 5.734; 95% CI, 3.007-10.936; p<0.001) were independent predictors of overall survival. Adjuvant XELOX and S-1 regimen did not prove anything superior for stage III gastric cancer in this study. But, XELOX had a tendency to be superior to S-1 in stage IIIC gastric cancer after D2 gastrectomy although the difference was not statistically significant. N stage and cycle completion as planned were prognostic factors.

Adjuvant chemotherapy with S-1 for resected pancreatic cancer demonstrated survival benefits compared with gemcitabine in the JASPAC 01 trial. We investigated the effect of these agents on health-related quality of life (HRQOL) of patients in the JASPAC 01 trial. Patients with resected pancreatic cancer were randomly assigned to receive gemcitabine (1000 mg/m 2 weekly for three of four weeks for up to six cycles) or S-1 (40, 50, or 60 mg twice daily for four of six weeks for up to four cycles). HRQOL was assessed using the EuroQol-5D-3L (EQ-5D) questionnaire at baseline, months three and six, and every 6 months thereafter. HRQOL end-points included change in EQ-5D index from baseline, responses to five items in the EQ-5D, and quality-adjusted life months up to 24 months. Of randomised 385 patients, 354 patients were included in HRQOL analysis. Mean change in the EQ-5D index was similar in the S-1 and gemcitabine groups within 6 months from treatment initiation (difference, 0.024; P = 0.112), whereas corresponding mean from 12 to 24 months was better in the S-1 group than in the gemcitabine group (difference, 0.071; P < 0.001). Problems in mobility and pain/discomfort were also less frequent in the S-1 group than in the gemcitabine group in that period. Quality-adjusted life months were longer in the S-1 group than in the gemcitabine group (P < 0.001). Adjuvant chemotherapy with S-1 does not improve HRQOL within 6 months from treatment initiation but does improve HRQOL thereafter and quality-adjusted life months. UMIN000000655 at UMIN CTR.

In 2006, the Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer (ACTS-GC) demonstrated that S-1 is an effective adjuvant therapy for gastric cancer. Following that study, S-1 has been used as the standard adjuvant therapy for gastric cancer in Japan. However, the 1-year completion rate was only 65.8% in the ACTS-GC study and feasibility remains a critical issue. We conducted a study to evaluate the feasibility of 2 weekly administration regimens of S-1 as adjuvant chemotherapy in gastric cancer. The criteria for eligibility included histologically proven stage II (excluding T1), IIIA or IIIB gastric cancer with D2 lymph-node dissection. The patients were randomly assigned to either arm A (S-1 administration for 4 weeks followed by 2 weeks of rest) or arm B (S-1 administration for 2 weeks followed by 1 week of rest). In each arm, treatment was continued for 12 months unless recurrence or severe adverse events were observed. The primary endpoint was feasibility (protocol treatment completion rate). The secondary endpoints were safety, relapse-free survival and overall survival. A total of 47 patients were assigned to arms A or B between May, 2008 and February, 2010. During the first interim analysis, the protocol treatment completion rates in arms A and B were 83 and 100%, respectively at 6 months and 49 and 89%, respectively, at 12 months (P=0.0046). Therefore, S-1 administration for 2 weeks followed by 1 week rest was more feasible as adjuvant chemotherapy in gastric cancer. Grade 3 adverse events in arm A included fatigue (8.0%), anorexia (8.0%), nausea (4.0%), vomiting (4.0%) and hand-foot syndrome (4.0%), whereas none were observed in arm B. There were no reported grade 4 adverse events in either arm. In conclusion, the 2-week S-1 administration followed by 1-week rest regimen appears to be a more feasible oral administration regimen for S-1 as adjuvant chemotherapy in gastric cancer.

2018-01-01

Adjuvant platinum based chemotherapy is accepted as standard of care in stage II and III non-small cell lung cancer (NSCLC) patients and is often considered in patients with stage IB disease who have tumors ≥ 4 cm. The survival advantage is modest with approximately 5% at 5 years. Areas covered: This review article presents relevant data regarding chemotherapy use in the perioperative setting for early stage NSCLC. A literature search was performed utilizing PubMed as well as clinical trial.gov. Randomized phase III studies in this setting including adjuvant and neoadjuvant use of chemotherapy as well as ongoing trials on targeted therapy and immunotherapy are also discussed. Expert commentary: With increasing utilization of screening computed tomography scans, it is possible that the percentage of early stage NSCLC patients will increase in the coming years. Benefits of adjuvant chemotherapy in early stage NSCLC patients remain modest. There is a need to better define patients most likely to derive survival benefit from adjuvant therapy and spare patients who do not need adjuvant chemotherapy due to the toxicity of such therapy. Trials for adjuvant targeted therapy, including adjuvant EGFR-TKI trials and trials of immunotherapy drugs are ongoing and will define the role of these agents as adjuvant therapy.

Purpose: Large randomized trials have demonstrated significant survival benefits with the use of adjuvant chemotherapy or chemoradiation therapy for gastric cancer. The importance of adjuvant radiation therapy (RT) remains unclear. We performed an up-to-date meta-analysis of randomized trials testing the use of RT for resectable gastric cancer. Methods and Materials: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for randomized trials testing adjuvant (including neoadjuvant) RT for resectable gastric cancer. Hazard ratios describing the impact of adjuvant RT on overall survival (OS) and disease-free survival (DFS) were extracted directly from the original studies or calculated frommore » survival curves. Pooled estimates were obtained using the inverse variance method. Subgroup analyses were performed to determine whether the efficacy of RT varies with chemotherapy use, RT timing, geographic region, type of nodal dissection performed, or lymph node status. Results: Thirteen studies met all inclusion criteria and were used for this analysis. Adjuvant RT was associated with a significant improvement in both OS (HR = 0.78, 95% CI: 0.70-0.86, P<.001) and DFS (HR = 0.71, 95% CI: 0.63-0.80, P<.001). In the 5 studies that tested adjuvant chemoradiation therapy against adjuvant chemotherapy, similar effects were seen for OS (HR = 0.83, 95% CI: 0.67-1.03, P=.087) and DFS (HR = 0.77, 95% CI: 0.91-0.65, P=.002). Available data did not reveal any subgroup of patients that does not benefit from adjuvant RT. Conclusion: In randomized trials for resectable gastric cancer, adjuvant RT provides an approximately 20% improvement in both DFS and OS. Available data do not reveal a subgroup of patients that does not benefit from adjuvant RT. Further study is required to optimize the implementation of adjuvant RT for gastric cancer with regard to patient selection and integration with systemic therapy.« less

Purpose Geographic access to care may be associated with receipt of chemotherapy but has not been fully examined. This study sought to evaluate the association between density of oncologists and travel distance and receipt of adjuvant chemotherapy for colon cancer within 90 days of colectomy. Patients and Methods Patients in the National Cancer Data Base with stage III colon cancer, diagnosed between 2007 and 2010, and age 18 to 80 years were selected. Generalized estimating equation clustering by hospital service area was conducted to examine the association between geographic access and receipt of oncology services, controlling for patient sociodemographic and clinical characteristics. Results Of 34,694 patients in the study cohort, 75.7% received adjuvant chemotherapy within 90 days of colectomy. Compared with travel distance less than 12.5 miles, patients who traveled 50 to 249 miles (odds ratio [OR], 0.87; P = .009) or ≥ 250 miles (OR, 0.36; P < .001) had decreased likelihood of receiving adjuvant chemotherapy. Density level of oncologists was not statistically associated with receipt of adjuvant chemotherapy (low v high density: OR, 0.98; P = .77). When stratifying analyses by insurance status, non–privately insured patients who resided in areas with low density of oncologists were less likely to receive adjuvant chemotherapy (OR, 0.85; P = .03). Conclusion Increased travel burden was associated with a decreased likelihood of receiving adjuvant chemotherapy, regardless of insurance status. Patients with nonprivate insurance who resided in low-density oncologist areas were less likely to receive adjuvant chemotherapy. If these findings are validated prospectively, interventions to decrease geographic barriers may improve the timeliness and quality of colon cancer treatment. PMID:26304878

Purpose The Medical Research Council Adjuvant Gastric Infusional Chemotherapy (MAGIC) trial established perioperative epirubicin, cisplatin, and fluorouracil chemotherapy as a standard of care for patients with resectable esophagogastric cancer. However, identification of patients at risk for relapse remains challenging. We evaluated whether pathologic response and lymph node status after neoadjuvant chemotherapy are prognostic in patients treated in the MAGIC trial. Materials and Methods Pathologic regression was assessed in resection specimens by two independent pathologists using the Mandard tumor regression grading system (TRG). Differences in overall survival (OS) according to TRG were assessed using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate analyses using the Cox proportional hazards method established the relationships among TRG, clinical-pathologic variables, and OS. Results Three hundred thirty resection specimens were analyzed. In chemotherapy-treated patients with a TRG of 1 or 2, median OS was not reached, whereas for patients with a TRG of 3, 4, or 5, median OS was 20.47 months. On univariate analysis, high TRG and lymph node metastases were negatively related to survival (Mandard TRG 3, 4, or 5: hazard ratio [HR], 1.94; 95% CI, 1.11 to 3.39; P = .0209; lymph node metastases: HR, 3.63; 95% CI, 1.88 to 7.0; P < .001). On multivariate analysis, only lymph node status was independently predictive of OS (HR, 3.36; 95% CI, 1.70 to 6.63; P < .001). Conclusion Lymph node metastases and not pathologic response to chemotherapy was the only independent predictor of survival after chemotherapy plus resection in the MAGIC trial. Prospective evaluation of whether omitting postoperative chemotherapy and/or switching to a noncross-resistant regimen in patients with lymph node-positive disease whose tumor did not respond to preoperative epirubicin, cisplatin, and fluorouracil may be appropriate.

Evidence on adjuvant chemotherapy in older women with breast cancer is poor. We tested whether weekly docetaxel is more effective than standard chemotherapy. We carried out a multicenter, randomized phase III study. Women aged 65-79, operated for breast cancer, with average to high risk of recurrence, were allocated 1 : 1 to CMF (cyclophosphamide 600 mg/m², methotrexate 40 mg/m², fluorouracil 600 mg/m², days 1, 8) or docetaxel (35 mg/m(2) days 1, 8, 15) every 4 weeks, for four or six cycles according to hormone receptor status. Primary end point was disease-free survival (DFS). A geriatric assessment was carried out. Quality of life (QoL) was assessed with EORTC C-30 and BR-23 questionnaires. From July 2003 to April 2011, 302 patients were randomized and 299 (152 allocated CMF and 147 docetaxel) were eligible. After 70-month median follow-up, 109 DFS events were observed. Unadjusted hazard ratio (HR) of DFS for docetaxel versus CMF was 1.21 [95% confidence interval (CI) 0.83-1.76, P = 0.32]; DFS estimate at 5 years was 0.69 with CMF and 0.65 with docetaxel. HR of death was 1.34 (95% CI 0.80-2.22, P = 0.26). There was no interaction between treatment arms and geriatric scales measuring patients' ability or comorbidities. Hematological toxicity, mucositis and nausea were worse with CMF; allergy, fatigue, hair loss, onychopathy, dysgeusia, diarrhea, abdominal pain, neuropathy, cardiac and skin toxicity were worse with docetaxel. One death was attributed to CMF and two to docetaxel. Increasing age, impairment in instrumental daily living activities, number of comorbidities and docetaxel treatment were independently associated with severe nonhematological toxicity. QoL was worse with docetaxel for nausea-vomiting, appetite loss, diarrhea, body image, future perspective, treatment side-effects and hair loss items. Weekly docetaxel is not more effective than standard CMF as adjuvant treatment of older women with breast cancer and worsens QoL and toxicity. NCT00331097

Although irinotecan and oxaliplatin are both standard treatments for advanced colon cancer, it remains unknown whether either is effective for patients with resectable synchronous colon cancer and liver-confined metastasis (SCCLM) after curative surgery. A population-based cohort of patients diagnosed with de novo SCCLM between 2004 and 2009 was established by searching the database of the Taiwan Cancer Registry and the National Health Insurance Research Database of Taiwan. Patients who underwent curative surgery as their first therapy followed by chemotherapy doublets were classified into the irinotecan group or oxaliplatin group accordingly. Patients who received radiotherapy or did not receive chemotherapy doublets were excluded. We included 6,533 patients with de novo stage IV colon cancer. Three hundred and nine of them received chemotherapy doublets after surgery; 77 patients received irinotecan and 232 patients received oxaliplatin as adjuvant chemotherapy. The patients in both groups exhibited similar overall survival (median: not reached vs. 40.8 months, p=0.151) and time to the next line of treatment (median: 16.5 vs. 14.3 months, p=0.349) in both univariate and multivariate analyses. Additionally, patients with resectable SCCLM had significantly shorter median overall survival than patients with stage III colon cancer who underwent curative surgery and subsequent adjuvant chemotherapy, but longer median overall survival than patients with de novo stage IV colon cancer who underwent surgery only at the primary site followed by standard systemic chemotherapy (p<0.001). Irinotecan and oxaliplatin exhibited similar efficacy in patients who underwent curative surgery for resectable SCCLM. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

for the CSG would be less than US$13,527/QALY (three times the per capita gross domestic product of China). For patients in China with resectable disease, our results suggest that adjuvant chemotherapy with capecitabine plus oxaliplatin after a D2 gastrectomy is cost-saving and dominant in the long run on the basis of a current clinical trial, compared with treatment with a D2 gastrectomy alone.

Hu-antigen R (HuR) is an RNA-binding protein that regulates the stability, translation, and nucleus-to-cytoplasm translocation of messenger RNAs (mRNAs). The aim of this study was to investigate the prognostic significance of HuR in cholangiocarcinoma patients who received adjuvant gemcitabine-based chemotherapy (AGC) after surgical resection. Nuclear and cytoplasmic HuR expression was investigated immunohistochemically in 131 patients with resected cholangiocarcinoma, including 91 patients administered AGC and 40 patients who did not receive adjuvant chemotherapy. The correlation between HuR expression and survival was evaluated by statistical analysis. High nuclear and cytoplasmic HuR expression was observed in 67 (51%) and 45 (34%) patients, respectively. Cytoplasmic HuR expression was significantly associated with lymph node metastasis (p < 0.01), while high cytoplasmic HuR expression was significantly associated with poor disease-free survival [DFS] (p = 0.03) and overall survival [OS] (p = 0.001) in the 91 patients who received AGC, but not in the 40 patients who did not receive AGC (DFS p = 0.17; OS p = 0.07). In the multivariate analysis of patients who received AGC, high cytoplasmic HuR expression was an independent predictor of poor DFS (hazard ratio [HR] 1.77; p = 0.04) and OS (HR 2.09; p = 0.02). Nuclear HuR expression did not affect the survival of enrolled patients. High cytoplasmic HuR expression was closely associated with the efficacy of AGC in patients with cholangiocarcinoma. The current findings warrant further investigations to optimize adjuvant chemotherapy regimens for resectable cholangiocarcinoma.

This study investigated the cost effectiveness of guideline-recommended (American Society of Clinical Oncology, European Society of Medical Oncology) urokinase plasminogen activator (uPA)/plasminogen activator inhibitor-1 (PAI-1) biomarkers to guide adjuvant chemotherapy decisions for hormone receptor-positive, node-negative early breast cancer patients at intermediate risk of relapse, in France, Germany, and The Netherlands. uPA/PAI-1 testing was compared to chemotherapy for all patients and to no chemotherapy in two age-related subgroups (35-49 and 50-75 years). A partitioned survival analysis was performed using patient-level data for survival outcomes and secondary sources. Mean quality-adjusted life years (QALYs) and costs were estimated over a lifetime horizon to calculate the incremental net monetary benefit (INMB) at a willingness-to-pay of €50,000/QALY. Uncertainty was explored through bootstrap and probabilistic sensitivity analysis using 5000 replicates. In the 35-49 year age group, INMBs were negative when uPA/PAI-1 testing was compared to chemotherapy for all patients but positive when it was compared to no chemotherapy for the three countries. In the 50-75 year age group, INMBs of uPA/PAI-1 testing compared to both reference strategies were positive in the three countries, with cost-effectiveness probabilities for the uPA/PAI-1 strategy of 65%, 70%, and 59% for France, Germany, and the Netherlands, respectively, compared with chemotherapy for all patients, and 64%, 58%, and 65%, respectively, compared with no chemotherapy. uPA/PAI-1 testing could allow the selection of patients older than 50 years requiring chemotherapy in this population, but the cost effectiveness of this strategy is uncertain. Chemotherapy for all patients is the most cost-effective strategy for patients younger than 50 years. Copyright © 2016 Elsevier Ltd. All rights reserved.

Adjuvant therapy for gastric cancer: what have we learned since INT0116?

PubMed

Jácome, Alexandre A; Sankarankutty, Ajith K; dos Santos, José Sebastião

2015-04-07

Gastric cancer is one of the main cancer-related causes of death worldwide. The curative treatment of gastric cancer consists of tumor resection and lymphadenectomy. However, surgical treatment alone is associated with high recurrence rates. Adjuvant treatment strategies have been studied over the last decades, but there have been controversial results from the initial studies. The pivotal INT0116 study demonstrated that the use of adjuvant chemoradiotherapy with 5-fluorouracil increases relapse-free and overall survival, and it has been adopted across the Western world. The high toxicity of radiochemotherapy and suboptimal surgical treatment employed, with fewer than 10% of the patients submitted to D2 lymphadenectomy, were the main study limitations. Since its publication, other adjuvant treatment modalities have been studied, and radiochemotherapy is being refined to improve its efficacy and safety. A multimodal approach has been demonstrated to significantly increase relapse-free and overall survival, and it can be offered in the form of perioperative chemotherapy, adjuvant chemoradiotherapy or adjuvant chemotherapy, regardless of the extent of lymphadenectomy. The objective of the present review is to report the major advances obtained in the last decades in the adjuvant treatment of gastric cancer as well as the perspectives of treatment based on recent knowledge of the molecular biology of the disease.

Whether Neo-adjuvant chemotherapy can affect patients' postoperative brain function is not clear. In this study, we investigated the effect of preoperative cisplatin treatment on postoperative cognitive function and its possible mechanism in rats. Moreover, we also tested whether the NMDAR inhibitor memantine could attenuate cisplatin-induced alterations. 12-month-oldSprague-Dawley rats randomly received an intraperitoneal injection of either cisplatin once a week at a dose of 3mg/kg for three consecutive weeks or an equivalent volume of normal saline. After the injections, the normal saline injection group was divided into 3 groups (n=5 each): a normal saline group (group S), normal saline+pentobarbital group (group SP), and normal saline+pentobarbital+operation group (group SPO).The cisplatin injection group was divided into 3 groups: a cisplatin group (group C), cisplatin+pentobarbital group (group CP), and cisplatin+pentobarbital+operation group (group CPO).Rats in the group SP, SPO,CP and CPO were anaesthetized with sodium pentobarbital and then the SPO and CPO groups underwent a simple laparotomy operation. The effects of memantine were tested through two additional groups of rats (cisplatin+memantine group (group CM) and cisplatin+pentobarbital+operation+memantine group (group CPOM)). A Morris water maze test was performed to evaluate the spatial learning and memory ability five days after anesthesia or operation. After the test, the hippocampi were removed for detection of the expression of NMDAR by western bloting. The relevant protein expression levels of PSD95 and ERK1/2 were detected by western blot analysis. Rats treated with cisplatin had a longer mean escape latency and spent a shorter amount of time in the target quadrant than did the normal saline injection rats. Furthermore, the protein expression levels of NMDA receptors, PSD95 and ERK1/2 were decreased in cisplatin group and memantine could up-regulate their expression. These results suggest

Cancer chemotherapy is frequently associated with a decline in general physical condition, exercise tolerance, and muscle strength and with an increase in fatigue. While accumulating evidence suggests that physical activity and exercise interventions during chemotherapy treatment may contribute to maintaining cardiorespiratory fitness and strength, the results of studies conducted to date have not been consistent. Additional research is needed to determine the optimal intensity of exercise training programs in general and in particular the relative effectiveness of supervised, outpatient (hospital- or physical therapy practice-based) versus home-based programs. This multicenter, prospective, randomized trial will evaluate the effectiveness of a low to moderate intensity, home-based, self-management physical activity program, and a high intensity, structured, supervised exercise program, in maintaining or enhancing physical fitness (cardiorespiratory fitness and muscle strength), in minimizing fatigue and in enhancing the health-related quality of life (HRQoL). Patients receiving adjuvant chemotherapy for breast or colon cancer (n = 360) are being recruited from twelve hospitals in the Netherlands, and randomly allocated to one of the two treatment groups or to a 'usual care' control group. Performance-based and self-reported outcomes are assessed at baseline, at the end of chemotherapy and at six month follow-up. This large, multicenter, randomized clinical trial will provide additional empirical evidence regarding the effectiveness of physical exercise during adjuvant chemotherapy in enhancing physical fitness, minimizing fatigue, and maintaining or enhancing patients' quality of life. If demonstrated to be effective, exercise intervention programs will be a welcome addition to the standard program of care offered to patients with cancer receiving chemotherapy. This study is registered at the Netherlands Trial Register (NTR 2159).

Abstract Background There is an ongoing debate about the value of (neo‐)adjuvant chemotherapy in high‐ and intermediate‐grade osteosarcoma of the head and neck. Methods All records of patients older than 16 years diagnosed with osteosarcoma of the head and neck in the Netherlands between 1993 and 2013 were reviewed. Results We identified a total of 77 patients with an osteosarcoma of the head and neck; the 5‐year overall survival (OS) was 55%. In 50 patients with surgically resected high‐ or intermediate‐grade osteosarcoma of the head and neck younger than 75 years, univariate and multivariable analysis, adjusting for age and resection margins, showed that patients who had not received chemotherapy had a significantly higher risk of local recurrence (hazard ratio [HR] = 3.78 and 3.66, respectively). Conclusion In patients younger than 75 years of age with surgically resected high‐ and intermediate‐grade osteosarcoma of the head and neck, treatment with (neo‐)adjuvant chemotherapy resulted in a significantly smaller risk of local recurrence. Therefore, we suggest (neo‐)adjuvant chemotherapy in patients amenable to chemotherapy. © 2016 The Authors Head & Neck Published by Wiley Periodicals, Inc. Head Neck 39: 140–146, 2017 PMID:27507299

Adjuvant chemotherapy after surgery improves survival of patients with stage II-III, resectable gastric cancer. However, the overall survival benefit observed after adjuvant chemotherapy is moderate, suggesting that not all patients with resectable gastric cancer treated with adjuvant chemotherapy benefit from it. We aimed to develop and validate a predictive test for adjuvant chemotherapy response in patients with resectable, stage II-III gastric cancer. In this multi-cohort, retrospective study, we developed through a multi-step strategy a predictive test consisting of two rule-based classifier algorithms with predictive value for adjuvant chemotherapy response and prognosis. Exploratory bioinformatics analyses identified biologically relevant candidate genes in gastric cancer transcriptome datasets. In the discovery analysis, a four-gene, real-time RT-PCR assay was developed and analytically validated in formalin-fixed, paraffin-embedded (FFPE) tumour tissues from an internal cohort of 307 patients with stage II-III gastric cancer treated at the Yonsei Cancer Center with D2 gastrectomy plus adjuvant fluorouracil-based chemotherapy (n=193) or surgery alone (n=114). The same internal cohort was used to evaluate the prognostic and chemotherapy response predictive value of the single patient classifier genes using associations with 5-year overall survival. The results were validated with a subset (n=625) of FFPE tumour samples from an independent cohort of patients treated in the CLASSIC trial (NCT00411229), who received D2 gastrectomy plus capecitabine and oxaliplatin chemotherapy (n=323) or surgery alone (n=302). The primary endpoint was 5-year overall survival. We identified four classifier genes related to relevant gastric cancer features (GZMB, WARS, SFRP4, and CDX1) that formed the single patient classifier assay. In the validation cohort, the prognostic single patient classifier (based on the expression of GZMB, WARS, and SFRP4) identified 79 (13%) of 625

This study investigated the prognostic value of tumor-infiltrating lymphocyte (TIL) density as determined by molecular subtype and receipt of adjuvant chemotherapy in invasive breast cancer (IBC). Stromal TIL densities were evaluated in 1489 IBC samples using recommendations proposed by the International TILs Working Group. Cases were allocated to high- and low-TIL density groups using a cutoff of 10%. Of the 1489 IBC patients, 427 (28.7%) were assigned to the high-TIL group and 1062 (71.3%) to the low-TIL group. High TIL density was found to be significantly associated with large tumor size (p = 0.001), high histologic grade (p < 0.001), and high Ki-67 labeling index (p < 0.001). Triple-negative and human epidermal growth factor receptor 2 (HER2)-positive subtypes had significantly higher TIL densities than luminal A or B (HER2-negative) subtypes (p < 0.001). High TIL density was significantly associated with prolonged disease-free survival (DFS) by univariate (p < 0.001) and multivariate (p < 0.001) analyses. In the low-TIL-density group, the patients who did not receive adjuvant chemotherapy showed better DFS (p < 0.001), but no such survival difference was observed in the high-TIL group (p = 0.222). For the patients who received adjuvant anthracycline, high-TIL density was found to be an independent prognostic factor of favorable DFS in the luminal B (HER2-negative; p = 0.003), HER2-positive (p = 0.019), and triple-negative (p = 0.017) subtypes. Measurements of TIL density in routine clinical practice could give useful prognostic information for the triple-negative, HER2-positive, and luminal B (HER2-negative) IBC subtypes, especially for patients administered adjuvant anthracycline.

Background The International Duration Evaluation of Adjuvant chemotherapy project investigated whether a shorter duration of oxaliplatin-based adjuvant chemotherapy was as effective as 6 months of identical chemotherapy for resected stage III colon cancer. As part of this project, we report safety data from the Japanese ACHIEVE study (JFMC47-1202-C3). Patients and methods ACHIEVE was an open-label, multicentre trial randomising patients with stage III colon cancer to receive 3 m or 6 m of mFOLFOX6/CAPOX after surgery. Choice of regimen was declared before randomisation by a site investigator. Results Between August 2012 and June 2014, 1313 patients were enrolled and, of those, 1277 were analysed for the safety analysis, with 635 in arm 6 (mFOLFOX6, n=158; CAPOX, n=477) and 642 in arm 3 (mFOLFOX6, n=161; CAPOX, n=481). Grade 3 or worse peripheral sensory neuropathy (PSN) developed in 5%/0.6% of patients receiving mFOLFOX6 in arm 6/3 (p=0.019) and 6%/1% of those receiving CAPOX in arm 6/3 (p<0.001). Similarly, grade 2 or worse PSN developed in 36%/11% of patients receiving mFOLFOX6 in arm 6/3 (p<0.001) and 37%/14% of those receiving CAPOX in arm 6/3 (p<0.001). An association between baseline creatinine clearance (CCr) and adverse events (AEs) was found that patients with CAPOX were significantly more likely to develop AEs ≥grade 3 when they had a CCr ≤50 (OR 1.67; p=0.048). Conclusions We confirmed in the Japanese population that the shorter duration of adjuvant chemotherapy resulted in a significant reduction of PSN. In patients with CAPOX, renal function was significantly related to severe AEs. Trial registration number UMIN000008543, Results. PMID:29713499

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

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

Findings show that there is a certain degree of refusal on the part of breast cancer patients to undergo adjuvant therapy. Accordingly, the major goals of the study were, first, to learn more about the beliefs of breast cancer patients in regard to adjuvant therapy; second, to find out about the sources of the patients' beliefs; and third, to learn about the attitudes of oncologists concerning the same aspects of adjuvant therapy to which the patients' beliefs referred. The participants were 92 breast cancer patients (mean age 61.2) and 57 doctors of both genders specialized in oncology or affiliated domains. Both groups were administered questionnaires referring to goals of adjuvant treatment, the chances of attaining these goals, side effects, and difficulty of the treatment. Doctors were specifically asked about the views they thought proper to communicate to patients in regard to the mentioned issues. Patients were also asked about whether they had doubts about the treatment and sources of information. The findings showed disparities between the views of patients and doctors in regard to goals, chances of attainment, side effects, and difficulty of treatment. Patients endorsed more goals than doctors and tended to assign to them lower chances of attainment. Doctors were divided in their views about whether to communicate the side effects and difficulties. The results reveal the importance of outlining goals for patients undergoing adjuvant treatment and the disagreements between doctors about what should be communicated to patients, and highlight the complexity of providing to patients information that is both scientifically correct and emotionally helpful.

Background: Peritumoral vascular invasion (PVI) may assist in assigning optimal adjuvant systemic therapy for women with early breast cancer. Patients and methods: Patients participated in two International Breast Cancer Study Group randomized trials testing chemoendocrine adjuvant therapies in premenopausal (trial VIII) or postmenopausal (trial IX) node-negative breast cancer. PVI was assessed by institutional pathologists and/or central review on hematoxylin–eosin-stained slides in 99% of patients (analysis cohort 2754 patients, median follow-up >9 years). Results: PVI, present in 23% of the tumors, was associated with higher grade tumors and larger tumor size (trial IX only). Presence of PVI increased locoregional and distant recurrence and was significantly associated with poorer disease-free survival. The adverse prognostic impact of PVI in trial VIII was limited to premenopausal patients with endocrine-responsive tumors randomized to therapies not containing goserelin, and conversely the beneficial effect of goserelin was limited to patients whose tumors showed PVI. In trial IX, all patients received tamoxifen: the adverse prognostic impact of PVI was limited to patients with receptor-negative tumors regardless of chemotherapy. Conclusion: Adequate endocrine adjuvant therapy appears to abrogate the adverse impact of PVI in node-negative disease, while PVI may identify patients who will benefit particularly from adjuvant therapy.

The optimal delay in the start of chemotherapy following rectal cancer surgery has not yet been identified. However, postponed adjuvant therapy has been proven to be connected with a significant survival detriment. We aimed to investigate whether the time to initiation of adjuvant treatment can be influenced by the application of minimally invasive surgery rather than traditional open surgery. By comprehensively evaluating the available inherent literature, several factors appear to be associated with delayed postoperative chemotherapy. Some of them are strictly related to surgical short-term outcomes. Laparoscopy results in shortened length of hospital stay, reduced surgical morbidity and lower rate of wound infection compared to conventional surgery. Probably due to such advantages, the application of minimally-invasive surgery to treat rectal malignancies seems to impact favorably the possibility to start adjuvant chemotherapy within an adequate timeframe following surgical resection, with potential improvement in patient survival.

Clinical trials have shown that trastuzumab, a recombinant monoclonal antibody against HER2 receptor, significantly improves overall survival and disease-free survival in women with HER2-positive early breast cancer, but long-term follow-up data are needed. We report the results of comparing observation with two durations of trastuzumab treatment at a median follow-up of 11 years, for patients enrolled in the HERA (HERceptin Adjuvant) trial. HERA (BIG 1-01) is an international, multicentre, open-label, phase 3 randomised trial of 5102 women with HER2-positive early breast cancer, who were enrolled from hospitals in 39 countries between Dec 7, 2001, and June 20, 2005. After completion of all primary therapy (including, surgery, chemotherapy, and radiotherapy as indicated), patients were randomly assigned (1:1:1) to receive trastuzumab for 1 year (once at 8 mg/kg of bodyweight intravenously, then 6 mg/kg once every 3 weeks) or for 2 years (with the same dose schedule), or to the observation group. Primary endpoint is disease-free survival, and analyses are in the intention-to-treat population. Hazard ratios (HRs) were estimated from Cox models, and survival curves were estimated by the Kaplan-Meier method. Comparison of 2 years versus 1 year of trastuzumab is based on 366-day landmark analyses. This study is registered with ClinicalTrials.gov (NCT00045032). Of the 5102 women randomly assigned in the HERA trial, three patients had no evidence of having provided written informed consent to participate. We followed up the intention-to-treat population of 5099 patients (1697 in observation, 1702 in 1-year trastuzumab, and 1700 in 2-years trastuzumab groups). After a median follow-up of 11 years (IQR 10·09-11·53), random assignment to 1 year of trastuzumab significantly reduced the risk of a disease-free survival event (HR 0·76, 95% CI 0·68-0·86) and death (0·74, 0·64-0·86) compared with observation. 2 years of adjuvant trastuzumab did not improve disease free

The purpose of this study was to evaluate the efficacy and toxicity of radiotherapy concurrently with weekly cisplatin, followed by adjuvant chemotherapy, for the treatment of N2–3 nasopharyngeal cancer (NPC) in Asian countries, especially regions of South and Southeast Asian countries where NPC is endemic. Between 2005 and 2009, 121 patients with NPC (T1–4 N2–3 M0) were registered from Vietnam, Malaysia, Indonesia, Thailand, The Philippines, China and Bangladesh. Patients were treated with 2D radiotherapy concurrently with weekly cisplatin (30 mg/m 2), followed by adjuvant chemotherapy, consisting of cisplatin (80 mg/m2 on Day 1) and fluorouracil (800 mg/m2 on Days 1–5) for 3 cycles. Of the 121 patients, 56 patients (46%) required interruption of RT. The reasons for interruption of RT were acute non-hematological toxicities such as mucositis, pain and dermatitis in 35 patients, hematological toxicities in 11 patients, machine break-down in 3 patients, poor general condition in 2 patients, and others in 8 patients. Of the patients, 93% completed at least 4 cycles of weekly cisplatin during radiotherapy, and 82% completed at least 2 cycles of adjuvant chemotherapy. With a median follow-up time of 46 months for the surviving 77 patients, the 3-year locoregional control, distant metastasis-free survival and overall survival rates were 89%, 74% and 66%, respectively. No treatment-related deaths occurred. Grade 3–4 toxicities of mucositis, nausea/vomiting and leukopenia were observed in 34%, 4% and 4% of the patients, respectively. In conclusion, further improvement in survival and locoregional control is necessary, although our regimen showed acceptable toxicities. PMID:23192700

Purpose: To evaluate the tolerability and toxicity of administering vaginal brachytherapy (VB) concurrently during chemotherapy compared with the sequential approach for patients with endometrial cancer. Methods and Materials: A retrospective analysis of 372 surgically staged patients with endometrial cancer American Joint Committee on Cancer 2009 stages I to IV treated with adjuvant postoperative radiation therapy (RT) at our institution from 2001 to 2012 was conducted. All patients received VB + external beam RT (EBRT) + 6 cycles of adjuvant carboplatin- and paclitaxel-based chemotherapy. The VB mean dose was 15.08 Gy (range, 15-20 Gy), with 3 to 4 weekly applications, andmore » the EBRT mean dose was 45 Gy delivered with 3-dimensional or intensity modulated RT techniques. Hematologic, gastrointestinal (GI), and genitourinary (GU) toxicities were assessed by Common Toxicity Criteria (CTC) and compared between sequential and concurrent chemotherapy and VB schedules. Results: Among patients who received RT and adjuvant chemotherapy, 180 of 372 patients (48%) received RT sandwiched between cycles 3 and 4 of chemotherapy. A separate group of 192 patients (52%) were treated with VB during the first 3 cycles of chemotherapy, with a weekly application on nonchemotherapy days, and received the EBRT portion in a sandwiched fashion. Patients treated with VB during chemotherapy had a decreased overall treatment time by 4 weeks (P<.001; 95% confidence interval: 3.99-4.02) and sustained no difference in CTC-graded acute hematologic, GI, or GU toxicities in comparison with the patients treated with VB and chemotherapy in a sequential manner (P>.05). CTC grade 3 or 4 hematologic, GI, and GU toxicities were zero. Conclusions: VB during chemotherapy is well tolerated, decreases overall treatment time, and does not render more toxicity than the sequential regimen.« less

Purpose Chemotherapy-induced amenorrhea is a serious concern for women undergoing cancer therapy. This prospective randomized trial evaluated the use of gonadotropin-releasing hormone (GnRH) analog triptorelin to preserve ovarian function in women treated with chemotherapy for early-stage breast cancer. Patients and Methods Premenopausal women age 44 years or younger were randomly assigned to receive either triptorelin or no triptorelin during (neo)adjuvant chemotherapy and were further stratified by age (< 35, 35 to 39, > 39 years), estrogen receptor status, and chemotherapy regimen. Objectives included the resumption of menses and serial monitoring of follicle-stimulating hormone (FSH) and inhibin A and B levels. Results Targeted for 124 patients with a planned 5-year follow-up, the trial was stopped for futility after 49 patients were enrolled (median age, 39 years; range, 21 to 43 years); 47 patients were treated according to assigned groups with four cycles of adriamycin plus cyclophosphamide alone or followed by four cycles of paclitaxel or six cycles of fluorouracil, epirubicin, and cyclophosphamide. Menstruation resumed in 19 (90%) of 21 patients in the control group and in 23 (88%) of 26 in the triptorelin group (P= .36). Menses returned after a median of 5.8 months (range, 1 to 19 months) after completion of chemotherapy in the triptorelin versus 5.0 months (range, 0 to 28 months) in the control arm (P= .58). Two patients (age 26 and 35 years at random assignment) in the control group had spontaneous pregnancies with term deliveries. FSH and inhibin B levels correlated with menstrual status. Conclusion When stratified for age, estrogen receptor status, and treatment regimen, amenorrhea rates on triptorelin were comparable to those seen in the control group. PMID:22231041

Geographic access to care may be associated with receipt of chemotherapy but has not been fully examined. This study sought to evaluate the association between density of oncologists and travel distance and receipt of adjuvant chemotherapy for colon cancer within 90 days of colectomy. Patients in the National Cancer Data Base with stage III colon cancer, diagnosed between 2007 and 2010, and age 18 to 80 years were selected. Generalized estimating equation clustering by hospital service area was conducted to examine the association between geographic access and receipt of oncology services, controlling for patient sociodemographic and clinical characteristics. Of 34,694 patients in the study cohort, 75.7% received adjuvant chemotherapy within 90 days of colectomy. Compared with travel distance less than 12.5 miles, patients who traveled 50 to 249 miles (odds ratio [OR], 0.87; P=.009) or ≥250 miles (OR, 0.36; P<.001) had decreased likelihood of receiving adjuvant chemotherapy. Density level of oncologists was not statistically associated with receipt of adjuvant chemotherapy (low v high density: OR, 0.98; P=.77). When stratifying analyses by insurance status, non-privately insured patients who resided in areas with low density of oncologists were less likely to receive adjuvant chemotherapy (OR, 0.85; P=.03). Increased travel burden was associated with a decreased likelihood of receiving adjuvant chemotherapy, regardless of insurance status. Patients with nonprivate insurance who resided in low-density oncologist areas were less likely to receive adjuvant chemotherapy. If these findings are validated prospectively, interventions to decrease geographic barriers may improve the timeliness and quality of colon cancer treatment. © 2015 by American Society of Clinical Oncology.

Music has been used as adjuvant therapy for anxiety and it is based on scientific principles. Tone, rhythm, harmony and time are crucial for its efficacy. Chemotherapy treatment frequently produces important stress in pediatric patients. This may delay treatment occasionally. Our objective was to determine if adjuvant therapy with music reduces anxiety in pediatric oncologic patients under ambulatory chemotherapy. Time series design. We included patients from 8 to 16 years of age who received ambulatory intravenous chemotherapy at the Hospital de Pediatría, Centro Médico Nacional Siglo XXI. They received treatment as usual on the first day, and music therapy during the second day of chemotherapy. A visual scale was used to categorize the level of anxiety prior and after treatment on both days. We included 22 patients. All patients experienced both moderate and high levels of anxiety prior to chemotherapy treatment on both days. There was a statistically significant reduction of anxiety on both groups after chemotherapy, but with lower levels of anxiety in the intervention group. There is an additional benefit with the use of music therapy in the reduction of anxiety in pediatric patients who receive ambulatory chemotherapy.

The aim of this study was to determine the treatment preferences (adjuvant goserelin or cyclophosphamide, methotrexate and fluorouracil (CMF) chemotherapy) of healthy premenopausal women should they hypothetically develop oestrogen-receptor (ER) positive early breast cancer. Two hundred pre or peri-menopausal women read two scenarios describing goserelin or chemotherapy. Information included: How and where treatments were administered, side-effects, their likely persistence and impact on fertility. Women stated their unprompted initial and final preferences with reasons for the choices made. Respondents showed an overwhelming preference for goserelin. 156 (78%) women favoured goserelin, 22 (11%) chemotherapy and 22 (11%) remained undecided (P<0.0001). Primary reasons for preferring goserelin for were 105 (71%) avoidance of chemotherapy side-effects, especially hair loss, perceived convenience and less disruption to normal life 54 (36%). The minority who preferred chemotherapy, valued the treatment finishing more quickly. These results together with clinical trial data showing equivalence of goserelin with CMF regimens suggest that premenopausal women with ER-positive tumours should at least be offered the choice of either adjuvant hormone therapy or chemotherapy.

Purpose: To evaluate the cosmetic results of sequential vs. concurrent adjuvant chemotherapy with radiotherapy after breast-conserving surgery for breast cancer, and to compare ratings by patients and physicians. Methods and Materials: From 1996 to 2000, 716 patients with Stage I-II breast cancers were included in a multicenter, Phase III trial (the ARCOSEIN study) comparing, after breast-conserving surgery with axillary dissection, sequential treatment with chemotherapy first followed by radiotherapy vs. chemotherapy administered concurrently with radiotherapy. Cosmetic results with regard to both the overall aspect of the breast and specific changes (color, scar) were evaluated in a total of 214 patients (107more » in each arm) by means of questionnaires to both the patient and a physician whose rating was blinded to treatment allocation. Results: Patients' overall satisfaction with cosmesis was not statistically different between the two arms, with approximately 92% with at least satisfactory results (p = 0.72), although differences between the treated and untreated breasts were greater after the concurrent regimen (29% vs. 14% with more than moderate differences; p 0.0015). Physician assessment of overall cosmesis was less favorable, with lower rates of at least satisfactory results in the concurrent arm (60% vs. 85%; p = 0.001). Consequently, the concordance for overall satisfaction with cosmesis between patients and doctors was only fair ({kappa} = 0.62). Conclusion: After breast-conserving surgery, the concurrent use of chemotherapy with radiotherapy is significantly associated with greater differences between the breasts. These differences do not translate into patients' lessened satisfaction with cosmesis.« less

Purpose Although adjuvant chemoradiotherapy for resected gallbladder cancer may improve survival for some patients, identifying which patients will benefit remains challenging because of the rarity of this disease. The specific aim of this study was to create a decision aid to help make individualized estimates of the potential survival benefit of adjuvant chemoradiotherapy for patients with resected gallbladder cancer. Methods Patients with resected gallbladder cancer were selected from the Surveillance, Epidemiology, and End Results (SEER) –Medicare database who were diagnosed between 1995 and 2005. Covariates included age, race, sex, stage, and receipt of adjuvant chemotherapy or chemoradiotherapy (CRT). Propensity score weighting was used to balance covariates between treated and untreated groups. Several types of multivariate survival regression models were constructed and compared, including Cox proportional hazards, Weibull, exponential, log-logistic, and lognormal models. Model performance was compared using the Akaike information criterion. The primary end point was overall survival with or without adjuvant chemotherapy or CRT. Results A total of 1,137 patients met the inclusion criteria for the study. The lognormal survival model showed the best performance. A Web browser–based nomogram was built from this model to make individualized estimates of survival. The model predicts that certain subsets of patients with at least T2 or N1 disease will gain a survival benefit from adjuvant CRT, and the magnitude of benefit for an individual patient can vary. Conclusion A nomogram built from a parametric survival model from the SEER-Medicare database can be used as a decision aid to predict which gallbladder patients may benefit from adjuvant CRT.

Chemotherapy-induced nausea and vomiting (CINV) remain among the most frequently reported distressing side effects associated with anthracycline-based chemotherapy despite significant advances in antiemetic management. The main risk factor for severity of CINV is the emetogenic potential of the chemotherapeutic agents. However, patient-related risk factors have been identified, including genetic makeup. Although studies have noted that ethnicity influences nausea and vomiting in other contexts, there is a paucity of research regarding the impact of ethnicity on CINV. This study was undertaken to evaluate whether Asian women receiving anthracycline-based chemotherapy experience more CINV than non-Asians. A retrospective, comparative, correlational chart review was performed to abstract the relevant variables. Data from a convenience sample of 358 women with breast cancer who received chemotherapy with doxorubicin between 2004 and 2008 at City of Hope in Duarte, California, were evaluated. The sample consisted of Caucasians (45%), Hispanics (27.7%), Asians (19.8%), and African Americans (7.5%). The results indicate that Asian women with breast cancer undergoing anthracycline-based chemotherapy experienced statistically significantly more clinically important CINV than their non-Asian counterparts. The data were collected retrospectively, with a certain population distribution at a specific time. This study provides interesting preliminary evidence that Asian ethnicity plays a role in the development of severe CINV. When managing chemotherapy toxicities in women with breast cancer, health-care providers should tailor therapy to individual risk profiles. Specifically, consideration of antiemetic therapy should accommodate patient characteristics, such as Asian descent. Copyright © 2012 Elsevier Inc. All rights reserved.

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. Preliminary clinical trial results have now been reported in both human and veterinary medicine, including adjuvant treatment of canine splenic hemangiosarcoma and incompletely resected soft tissue sarcoma, and, further, more powerful studies are currently ongoing.

Background Methylation levels of long interspersed nucleotide elements (LINE-1) are representative of genome-wide methylation status and crucial in maintaining genomic stability and expression. Their prognostic impact on colon cancer patients receiving adjuvant chemotherapy has not been well established. We evaluated the association between LINE-1 methylation status and clinicopathologic features and postoperative oncological outcomes in stage III colon cancer patients. Materials and Methods 129 UICC stage III colon cancer patients who had received radical resection and FOLFOX adjuvant chemotherapy were enrolled. Global methylation was estimated by analyzing tumor LINE-1 methylation status using bisulfite-polymerase chain reaction (PCR) and pyrosequencing assay. Demographics, clinicopathological data, and postoperative outcomes were recorded by trained abstractors. Outcome measurements included postoperative recurrence and disease-free survival. Univariate, multivariate, and survival analyses were conducted to identify prognostic factors of oncological outcomes. Results The LINE-1 methylation of all 129 patients was measured on a 0–100 scale (mean 63.3; median 63.7, standard deviation 7.1), LINE-1 hypomethylation was more common in patients aged 65 years and above (61.7%±7.6% vs. 64.6±6.4, p=0.019) and those with post-therapeutic recurrence (61.7±7.4 vs 64.3±6.7, p=0.041). Considering risk adjustment, LINE-1 hypomethylation was found to be an independent risk factor of post-therapeutic recurrence (Adjusted OR=14.1, p=0.012). Kaplan-Meier analysis indicated that patients in the low methylation group had shorter period of disease free survival (p=0.01). In a stratified analysis that included 48 patients with post-therapeutic recurrence, it was found that those who experienced shorter period of disease free survival (≦6 months) appeared to have lower LINE-1 methylation levels than patients who reported of recurrence after 6 months (56.68±15.75 vs. 63.55±7

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.

This study retrospectively describes the outcome of a series of 38 patients (pts) with T4 anal carcinoma exclusively treated by radio and chemotherapy. From 1992 to 2007, 38 pts with UST4-N0-2-M0 anal carcinoma were treated with exclusive radiotherapy and chemotherapy. All patients received external beam radiotherapy (EBRT) (median dose 45 Gy) with a concomitant chemotherapy (5-fluorouracil-cisplatin). Eleven patients received neo-adjuvant chemotherapy (5-fluorouracil-cisplatin). After 2-8 weeks, a 15-20 Gy boost was delivered either with EBRT (20 pts) or interstitial (192)Ir brachytherapy (18 pts). Mean follow-up was 66 months. After chemoradiation therapy (CRT), 13 pts (34%) had a complete response, 23 pts (60%) a response >50% (2 pts were not evaluated). The 5-year-disease-free survival was 79.2 ± 6.5%, and the 5-year overall survival was 83.9 ± 6%. Eight patients developed tumor progression (mean delay 8.8 months), six of them requiring a salvage surgery with definitive colostomy for local relapse. Late severe complication requiring colostomy was observed in 2 pts. The 5-year-colostomy-free survival was 78 ± 6.9%. Patients who received primary chemotherapy had a statistically significant better 5-year colostomy-free survival (100% vs. 38 ± 16.4%, P = 0.0006). T4 anal carcinoma can be treated with a curative intent using a sphincter-sparing approach of CRT, and neo-adjuvant chemotherapy should be considered prior to radiotherapy.

The 21-gene Recurrence Score (RS) result predicts outcome and chemotherapy benefit in node-negative and node-positive (N+), estrogen receptor-positive (ER+) patients treated with endocrine therapy. The purpose of this study was to evaluate the prognostic impact of RS results in N+, hormone receptor-positive (HR+) patients treated with adjuvant chemotherapy (6 cycles of FEC100 vs. 3 cycles of FEC100 followed by 3 cycles of docetaxel 100 mg/m 2 ) plus endocrine therapy (ET) in the PACS-01 trial (J Clin Oncol 2006;24:5664-5671). The current study included 530 HR+/N+ patients from the PACS-01 parent trial for whom specimens were available. The primary objective was to evaluate the relationship between the RS result and distant recurrence (DR). There were 209 (39.4%) patients with low RS (< 18), 159 (30%) with intermediate RS (18-30) and 162 (30.6%) with high RS (≥ 31). The continuous RS result was associated with DR (hazard ratio = 4.14; 95% confidence interval: 2.67-6.43; p <  0.001), adjusting for treatment. In multivariable analysis, the RS result remained a significant predictor of DR (p <  0.001) after adjustment for number of positive nodes, tumor size, tumor grade, Ki-67 (immunohistochemical status), and chemotherapy regimen. There was no statistically significant interaction between RS result and treatment in predicting DR (p = 0.79). After adjustment for clinical covariates, the 21-gene RS result is a significant prognostic factor in N+/HR+ patients receiving adjuvant chemoendocrine therapy. Not applicable.

We report a retrospective study of 47 consecutive patients with uterine sarcoma treated at the Churchill Hospital in Oxford between 1990-1998. The mainstay of treatment was surgery with adjuvant chemotherapy and radiotherapy reserved for selected patients with early stage disease. Overall 1 and 2 year survival was 49% and 30% respectively compared with 73% and 55% in the group who received adjuvant chemotherapy/radiotherapy. Median survival was 11 months for the group as a whole compared to 32.9 months in the adjuvant therapy group. This is a retrospective review with small numbers and considerable selection bias, however, given the poor survival of patients with this disease, adjuvant treatment should be considered in future trials of patients with uterine sarcoma.

The purpose of this study is to assess temporal trends in the use of granulocyte colony-stimulating factor (G-CSF) prophylaxis and risk of febrile neutropenia (FN) among older women receiving adjuvant chemotherapy for early-stage breast cancer. Women aged ≥ 66 years with diagnosis of early-stage breast cancer who initiated selected adjuvant chemotherapy regimens were identified using the SEER-Medicare data from 2002 to 2012. Adjusted, calendar-year-specific proportions were estimated for use of G-CSF primary prophylaxis (PP) and secondary prophylaxis and FN risk in the first and the second/subsequent cycles during the first course of chemotherapy, using logistic regression models. calendar-year-specific mean probabilities were estimated with covariates set to modal values. Among 11,107 eligible patients (mean age 71.7 years), 74% received G-CSF in the first course of chemotherapy. Of all patients, 5819 (52%) received G-CSF PP, and among those not receiving G-CSF PP, only 5% received G-CSF secondary prophylaxis. The adjusted proportion using G-CSF PP increased from 6% in 2002 to 71% in 2012. During the same period, the adjusted risk of FN in the first cycle increased from 2% to 3%; the adjusted risk increased from 1.5% to 2.9% among those receiving G-CSF PP and from 2.3% to 3.5% among those not receiving G-CSF PP. The use of G-CSF PP increased substantially during the study period. Although channeling of higher-risk patients to treatment with G-CSF PP is expected, the adjusted risk of FN among patients treated with G-CSF PP tended to be lower than among those not receiving G-CSF PP.

A randomized trial demonstrated that capecitabine is at least as effective as fluorouracil in the adjuvant treatment of patients with locally advanced rectal cancer. However, not all patients receive all planned cycles of chemotherapy. Therefore it is of interest how complete or partial administration of chemotherapy influences oncological outcome. A post hoc analysis of a trial with 401 randomized patients, nine being excluded because of missing data, was performed. 392 patients (197 - capecitabine, 195 - fluorouracil) could be analyzed regarding the number of administered adjuvant chemotherapy cycles. In the subgroup of 361 patients with an overall survival of at least six months, five-year overall and disease-free survival were analyzed in respect to completion (complete vs. incomplete) of chemotherapy cycles. Survival rates and curves were calculated and compared using the log-rank test. The effect of completion of chemotherapy was adjusted for relevant confounding factors. Two hundred fifty-one (64.0%) of analyzed patients received all postoperative scheduled cycles. Five-year overall survival was significantly better in these patients compared to the incomplete group (76.0 vs. 60.6%, p < 0.0001). Of 361 patients with an overall survival of at least six months, 251(69.5%) patients received all cycles. Five-year overall survival was also significantly better than in the incomplete group (76.0 vs. 66.4%, p = 0.0073). Five-year disease free survival was numerically better (64.9 vs. 58.7%, p = 0.0646; HR [not all cycles vs. all cycles] = 1.42 95% CI: [0.98, 2.07]). Cox regression models show a non-significant better OS (p = 0.061) and DFS (p = 0.083), if chemotherapy cycles were administered completely. Complete administration of chemotherapy cycles was associated with improved five-year overall and disease-free survival in patients with locally advanced rectal cancer.

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

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

This refined population represents an estimated incident population of 3,315 new breast cancers in Ontario (according to 2007 data). Currently it is estimated that only 15% of these women will develop a distant metastasis at 10 years; however, a far great proportion currently receive adjuvant chemotherapy, suggesting that more women are being treated with chemotherapy than can benefit. There is therefore a need to develop better prognostic and predictive tools to improve the selection of women that may benefit from adjuvant chemotherapy.

Cognitive Deficits in Breast Cancer Survivors After Chemotherapy and Hormonal Therapy.

2015-12-01

Adjuvant treatments, specifically chemotherapy and hormonal therapy, have dramatically increased breast cancer survival, resulting in increased attention to the residual effects of treatment. Breast cancer survivors (BCS) frequently report that cognitive deficits are a particular source of distress, interfering with many aspects of quality of life. The literature on neuropsychological performance measures in BCS supports the reality of subtle cognitive deficits after both chemotherapy and hormonal therapy. This premise is supported by recent imaging studies, which reveal anatomical changes after chemotherapy as well as changes in patterns of neural activation while performing cognitive tasks. This review suggests that, even when performance on neuropsychological performance measures is within normal limits, BCS may be using increased cognitive resources in the face of reduced cognitive reserve. Potential interventions for cognitive deficits after adjuvant therapy include prescriptions for healthy living, pharmacotherapy, complementary therapy, and cognitive remediation therapy directed toward specific cognitive deficits or a combination of several strategies.

Treatment of localized gastric cancer (LGC) consists of surgical resection followed by adjuvant treatment. Both chemoradiation (CRT) and chemotherapy (CT) regimens have shown benefit in survival outcomes versus observation. However, there are few data comparing these approaches. This study included consecutive patients with LGC treated at Instituto do Cancer do Estado de Sao Paulo (ICESP) from 2012 to 2015. CRT was based on the INT-0116 regimen and CT consisted of a platinum and fluoropyrimidine doublet. Treatment choice was based on physician preference. Toxicity was evaluated for every cycle. Overall survival (OS) analysis was performed by Kaplan-Meier. A propensity score-matched analysis was performed to minimize selection bias. A total of 309 patients were evaluated, 227 in CRT group and 82 in CT group. The most prevalent grade 3/4 toxicities in CRT and CT groups were: nausea/vomiting (9.25 vs 4.9%), fatigue (9.3% vs 2.4%), mucositis (4.4% vs 1.2%), neutropenia (37.8% vs 20.9%), febrile neutropenia (3.9% vs 0%), anemia (4.3% vs 6.1%), thrombocytopenia (2.6% vs 4.9%), neuropathy (0 vs 2.4%) and hand-foot syndrome (0.4% vs 2.4%). Two grade 5 toxicities (febrile neutropenia and anemia) occurred in CRT group. There was no difference in the pattern of recurrence. After a median follow-up of 23.5 months (CRT) and 20.6 months (CT), there was no difference in OS between groups. CT and CRT present similar efficacy and tolerability as adjuvant treatment for LGC.

Medulloblastoma (MB) is one of the most common primary central nervous system tumors in children. Data is lacking of a large cohort of medulloblastoma patients in China. Also, our knowledge on the sensitivity of different molecular subgroups of MB to adjuvant radiation therapy (RT) or chemotherapy (CHT) is still limited. The authors performed a retrospective study of 173 medulloblastoma patients treated at two institutions from 2002 to 2011. Formalin-fixed paraffin embedded (FFPE) tissues were available in all the cases and sections were stained to classify histological and molecular subgroups. Univariate and multivariate analyses were used to investigate prognostic factors. Of 173 patients, there were 118 children and 55 adults, 112 males and 61 females. Estimated 5-year overall survival (OS) rates for all patients, children and adults were 52%, 48% and 63%, respectively. After multivariate analysis, postoperative primary radiation therapy (RT) and chemotherapy (CHT) were revealed as favorable prognostic factors influencing OS and EFS. Postoperative primary chemotherapy (CHT) was found significantly improving the survival of children (p<0.001) while it was not a significant prognostic factor for adult patients. Moreover, patients in WNT subtype had better OS (p = 0.028) than others (SHH and Non-SHH/WNT subtypes) given postoperative adjuvant therapies. Postoperative primary RT was found to be a strong prognostic factor influencing the survival in all histological and molecular subgroups (p<0.001). Postoperative primary CHT was found significantly to influence the survival of classic medulloblastoma (CMB) (OS p<0.001, EFS p<0.001), SHH subgroup (OS p = 0.020, EFS p = 0.049) and WNT subgroup (OS p = 0.003, EFS p = 0.016) but not in desmoplastic/nodular medulloblastoma (DMB) (OS p = 0.361, EFS p = 0.834) and Non-SHH/WNT subgroup (OS p = 0.127, EFS p = 0.055). Our study showed postoperative primary CHT significantly influence the

Purpose Anthracycline- and taxane-based three-drug chemotherapy regimens have proven benefit as adjuvant therapy for early-stage breast cancer. This trial (NSABP B-38; Combination Chemotherapy in Treating Women Who Have Undergone Surgery for Node-Positive Breast Cancer) asked whether the incorporation of a fourth drug could improve outcomes relative to two standard regimens and provided a direct comparison of those two regimens. Patients and Methods We randomly assigned 4,894 women with node-positive early-stage breast cancer to six cycles of docetaxel, doxorubicin, and cyclophosphamide (TAC), four cycles of dose-dense (DD) doxorubicin and cyclophosphamide followed by four cycles of DD paclitaxel (P; DD AC→P), or DD AC→P with four cycles of gemcitabine (G) added to the DD paclitaxel (DD AC→PG). Primary granulocyte colony-stimulating factor support was required; erythropoiesis-stimulating agents (ESAs) were used at the investigator's discretion. Results There were no significant differences in 5-year disease-free survival (DFS) between DD AC→PG and DD AC→P (80.6% v 82.2%; HR, 1.07; P = .41), between DD AC→PG and TAC (80.6% v 80.1%; HR, 0.93; P = .39), in 5-year overall survival (OS) between DD AC→PG and DD AC→P (90.8% v 89.1%; HR, 0.85; P = .13), between DD AC→PG and TAC (90.8% v 89.6%; HR, 0.86; P = .17), or between DD AC→P versus TAC for DFS (HR, 0.87; P = .07) and OS (HR, 1.01; P = .96). Grade 3 to 4 toxicities for TAC, DD AC→P, and DD AC→PG, respectively, were febrile neutropenia (9%, 3%, 3%; P < .001), sensory neuropathy (< 1%, 7%, 6%; P < .001), and diarrhea (7%, 2%, 2%; P < .001). Exploratory analyses for ESAs showed no association with DFS events (HR, 1.02; P = .95). Conclusion Adding G to DD AC→P did not improve outcomes. No significant differences in efficacy were identified between DD AC→P and TAC, although toxicity profiles differed. PMID:23940225

Necrotizing fasciitis (NF) is a rare entity with its subacute form being even rarer. The condition has also been described to occur in the peristomal area in relation to different clinical scenarios. However, it has not been described in the setting of adjuvant chemotherapy where these medications have already been given. While the diagnosis may be delayed or missed due to the subtle symptomatology of the indolent subacute form of NF, another reason for a delayed or missed diagnosis may be the excessive use of tape and the stoma belt around the stomal appliance to prolong the life of the appliance beyond its recommended days of usage due to economic constraints. This, in turn, covers a larger area around the peristomal skin and developing skin changes associated with necrotizing fasciitis. Despite the less aggressive presentation of the subacute form, it may still represent a unique surgical challenge in this setting, as the chemotherapy-induced neutropenia bound to occur a few days after the chemotherapy may expose the patient to serious complications at that time. As such, the surgical plan at the time of presentation may become the determinant of morbidity and mortality. Here, a case is presented of a young patient who underwent abdominoperineal resection for stage III adenocarcinoma of the rectum. He was referred to us on the day of the fourth cycle of adjuvant chemotherapy by the oncology service where he had received part of his chemotherapy regimen. On presentation, he was found to be having significant skin changes in the peristomal area consistent with necrotizing fasciitis despite being clinically stable. The authors present this unique case as a study from which many lessons can be learned. They also explain the thought process behind a well-planned but simple surgical strategy that was implemented with a successful patient outcome. In addition to describing this surgical strategy, the case report is concluded by highlighting some factors that

Problems with attention and symptom distress are common clinical features reported by women who receive adjuvant chemotherapy for breast cancer. Mindfulness practice significantly improves attention and mindfulness programs significantly reduce symptom distress in patients with cancer, and, more specifically, in women with breast cancer. Recently, a pilot investigation of a music therapy program, built on core attitudes of mindfulness practice, reported significant benefits of enhanced attention and decreased negative mood and fatigue in women with breast cancer. This paper delineates the design and development of the mindfulness-based music therapy (MBMT) program implemented in that pilot study and includes clients’ narrative journal responses. Conclusions and recommendations, including recommendation for further exploration of the function of music in mindfulness practice are provided. PMID:27517966

Outcomes for early-stage breast cancer have improved. First-generation adjuvant chemotherapy trials reported a 0.27% 8-year cumulative incidence of myelodysplastic syndrome/acute myelogenous leukemia. Incomplete ascertainment and follow-up may have underestimated subsequent risk of treatment-associated marrow neoplasm (MN). We examined the MN frequency in 20,063 patients with stage I to III breast cancer treated at US academic centers between 1998 and 2007. Time-to-event analyses were censored at first date of new cancer event, last contact date, or death and considered competing risks. Cumulative incidence, hazard ratios (HRs), and comparisons with Surveillance, Epidemiology, and End Results estimates were obtained. Marrow cytogenetics data were reviewed. Fifty patients developed MN (myeloid, n = 42; lymphoid, n = 8) after breast cancer (median follow-up, 5.1 years). Patients who developed MN had similar breast cancer stage distribution, race, and chemotherapy exposure but were older compared with patients who did not develop MN (median age, 59.1 v 53.9 years, respectively; P = .03). Two thirds of patients had complex MN cytogenetics. Risk of MN was significantly increased after surgery plus chemotherapy (HR, 6.8; 95% CI, 1.3 to 36.1) or after all modalities (surgery, chemotherapy, and radiation; HR, 7.6; 95% CI, 1.6 to 35.8), compared with no treatment with chemotherapy. MN rates per 1,000 person-years were 0.16 (surgery), 0.43 (plus radiation), 0.46 (plus chemotherapy), and 0.54 (all three modalities). Cumulative incidence of MN doubled between years 5 and 10 (0.24% to 0.48%); 9% of patients were alive at 10 years. In this large early-stage breast cancer cohort, MN risk after radiation and/or adjuvant chemotherapy was low but higher than previously described. Risk continued to increase beyond 5 years. Individual risk of MN must be balanced against the absolute survival benefit of adjuvant chemotherapy. © 2014 by American Society of Clinical Oncology.

Adjuvant radiation therapy for pancreatic cancer: a review of the old and the new.

Surgery represents the only potential curative treatment option for patients diagnosed with pancreatic adenocarcinoma. Despite aggressive surgical management for patients deemed to be resectable, rates of local recurrence and/or distant metastases remain high, resulting in poor long-term outcomes. In an effort to reduce recurrence rates and improve survival for patients having undergone resection, adjuvant therapies (ATs) including chemotherapy and chemoradiation therapy (CRT) have been explored. While adjuvant chemotherapy has been shown to consistently improve outcomes, the data regarding adjuvant radiation therapy (RT) is mixed. Although the ability of radiation to improve local control has been demonstrated, it has not always led to improved survival outcomes for patients. Early trials are flawed in their utilization of sub-optimal radiation techniques, limiting their generalizability. Recent and ongoing trials incorporate more optimized RT approaches and seek to clarify its role in treatment strategies. At the same time novel radiation techniques such as intensity modulated RT (IMRT) and stereotactic body RT (SBRT) are under active investigation. It is hoped that these efforts will lead to improved disease-related outcomes while reducing toxicity rates.

Systemic and Adjuvant Therapies for Intrahepatic Cholangiocarcinoma.

PubMed

Chun, Yun Shin; Javle, Milind

2017-01-01

Intrahepatic cholangiocarcinoma represents the second most common primary liver cancer and is increasing in incidence. Most patients are diagnosed at an advanced, nonsurgical stage and only about 1 in 5 cases are surgically resectable. Despite surgery, the 5-year survival is low at only 30%. Multifocal, node- or margin-positive disease is at a higher risk of recurrence after resection. There is no level 1 evidence in support of postoperative adjuvant therapy. A recent adjuvant therapy phase III trial from the Partenariat de Recherche en Oncologie Digestive-Actions Concertées dans les Cancers Colo-Rectaux et Digestifs (PRODIGE) group reported no survival advantage with adjuvant gemcitabine and oxaliplatin therapy. Locally advanced or metastatic cholangiocarcinoma is treated with gemcitabine-based systemic chemotherapy with suboptimal response and survival. Integration of local therapy such as focal radiation along with induction chemotherapy is now being investigated in multicenter clinical trials. Recent molecular profiling studies have indicated that about 30% to 40% of intrahepatic cholangiocarcinoma cases have actionable mutations. These include fibroblast growth factor receptor (FGFR), isocitrate dehyrogenase 1 (IDH1), epidermal growth factor receptor (EGFR), and BRAF genetic aberrations. Clinical trials targeting these mutations as well as immune therapy using programmed cell death 1 (PD1) inhibitors indicated a promising early signal showing clinical efficacy.

Chemotherapy-induced amenorrhea is a serious concern for women undergoing cancer therapy. This prospective randomized trial evaluated the use of gonadotropin-releasing hormone (GnRH) analog triptorelin to preserve ovarian function in women treated with chemotherapy for early-stage breast cancer. Premenopausal women age 44 years or younger were randomly assigned to receive either triptorelin or no triptorelin during (neo)adjuvant chemotherapy and were further stratified by age (< 35, 35 to 39, > 39 years), estrogen receptor status, and chemotherapy regimen. Objectives included the resumption of menses and serial monitoring of follicle-stimulating hormone (FSH) and inhibin A and B levels. Targeted for 124 patients with a planned 5-year follow-up, the trial was stopped for futility after 49 patients were enrolled (median age, 39 years; range, 21 to 43 years); 47 patients were treated according to assigned groups with four cycles of adriamycin plus cyclophosphamide alone or followed by four cycles of paclitaxel or six cycles of fluorouracil, epirubicin, and cyclophosphamide. Menstruation resumed in 19 (90%) of 21 patients in the control group and in 23 (88%) of 26 in the triptorelin group (P= .36). Menses returned after a median of 5.8 months (range, 1 to 19 months) after completion of chemotherapy in the triptorelin versus 5.0 months (range, 0 to 28 months) in the control arm (P= .58). Two patients (age 26 and 35 years at random assignment) in the control group had spontaneous pregnancies with term deliveries. FSH and inhibin B levels correlated with menstrual status. When stratified for age, estrogen receptor status, and treatment regimen, amenorrhea rates on triptorelin were comparable to those seen in the control group.

Aim was to explore the association of ERCC1 and TS mRNA levels with the disease free survival (DFS) in Chinese colorectal cancer (CRC) patients receiving oxaliplatin and 5-FU based adjuvant chemotherapy. Total 112 Chinese stage II-III CRC patients were respectively treated by four different chemotherapy regimens after curative operation. The TS and ERCC1 mRNA levels in primary tumor were measured by real-time RT-PCR. Kaplan-Meier curves and log-rank tests were used for DFS analysis. The Cox proportional hazards model was used for prognostic analysis. In univariate analysis, the hazard ratio (HR) for the mRNA expression levels of TS and ERCC1 (logTS: HR = 0.820, 95% CI = 0.600 - 1.117, P = 0.210; logERCC1: HR = 1.054, 95% CI = 0.852 - 1.304, P = 0.638) indicated no significant association of DFS with the TS and ERCC1 mRNA levels. In multivariate analyses, tumor stage (IIIc: reference, P = 0.083; IIb: HR = 0.240, 95% CI = 0.080 - 0.724, P = 0.011; IIc: HR < 0.0001, P = 0.977; IIIa: HR = 0.179, 95% CI = 0.012 - 2.593, P = 0.207) was confirmed to be the independent prognostic factor for DFS. Moreover, the Kaplan-Meier DFS curves showed that TS and ERCC1 mRNA levels were not significantly associated with the DFS (TS: P = 0.264; ERCC1: P = 0.484). The mRNA expression of ERCC1 and TS were not applicable to predict the DFS of Chinese stage II-III CRC patients receiving 5-FU and oxaliplatin based adjuvant chemotherapy.

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

To determine the cost-effectiveness of dose-dense versus standard intravenous adjuvant chemotherapy for ovarian cancer using results from the no-bevacizumab cohort of the Gynecologic Oncology Group protocol 262 (GOG-262) randomized controlled trial, which reported a smaller absolute progression-free survival (PFS) benefit than the prior Japanese trial. A three-state Markov decision model from a healthcare system perspective with a 21day cycle length and 28month time-horizon was used to calculate incremental cost-effectiveness ratio (ICER) values per progression-free life-year saved (PFLYS) using results from GOG-262. Costs of chemotherapy, complications, and surveillance were from Medicare or institutional data. PFS, discontinuation, and complication rates were from GOG-262. Time-dependent transition probabilities and within-cycle corrections were used. One-way and probabilistic sensitivity analyses were performed. The model produces standard and dose-dense cohorts with 84.3% and 68.3% progression event proportions at 28months, matching GOG-262 rates at the trial's median follow-up. With a median PFS of 10.3months after standard chemotherapy and a hazard ratio for progression of 0.62 after dose-dense therapy, the ICER for dose-dense chemotherapy is $8074.25 (95% confidence interval: $7615.97-$10,207.16) per PFLYS. ICER estimates are sensitive only to the hazard ratio estimate but do not exceed $100,000 per PFLYS. 99.8% of ICER estimates met a more stringent willingness-to-pay of $50,000 per PFLYS. The willingness-to-pay value at which there is a 90% probability of dose-dense treatment being cost-effective is $12,000 per PFLYS. Dose-dense adjuvant chemotherapy is robustly cost-effective for advanced ovarian cancer from a healthcare system perspective based on results from GOG-262. Copyright © 2017 Elsevier Inc.

In this systematic review, we evaluated studies involving adjuvant and primary topical treatment for ocular surface squamous neoplasia (OSSN). The findings were: (i) adjuvant 5-fluorouracil (5-FU) reduces the risk of relapse after surgical excision with mild side effects [level Ib, grade of recommendation (GR) A]. (ii) Primary topical mitomycin (MMC) produces a high rate of complete response, low recurrence rate, and mild side effects (level Ib, GR A). (iii) Primary chemotherapy versus adjuvant chemotherapy produce similar rates of recurrence, with no significant difference (level IIb, GR B). (iv) Adjuvant 5-FU versus MMC showed no significant differences, with mild side effects in both groups and a better toxicity profile for MMC (level III, GR C). (v) Primary topical 5-FU versus MMC versus interferon (IFN) showed similar rates of tumor recurrence, mild side effects for all drugs, and more severe side effects in the 5-FU arm, followed successively by MMC and IFN (level III, GR C).

The 21-gene Oncotype DX Recurrence Score assay is a validated assay to help decide the appropriate treatment for estrogen receptor-positive (ER+), early-stage breast cancer (EBC) in the adjuvant setting. The choice of adjuvant treatments might vary considerably in different countries according to various treatment guidelines. This prospective multicenter study is the first to assess the impact of the Oncotype DX assay in the French clinical setting. A total of 100 patients with ER+, human epidermal growth factor receptor 2-negative EBC, and node-negative (pN0) disease or micrometastases in up to 3 lymph nodes (pN1mi) were enrolled. Treatment recommendations, physicians' confidence before and after knowing the Recurrence Score value, and physicians' perception of the assay were recorded. Of the 100 patients, 95 were evaluable (83 pN0, 12 pN1mi). Treatment recommendations changed in 37% of patients, predominantly from chemoendocrine to endocrine treatment alone. The proportion of patients recommended chemotherapy decreased from 52% pretest to 25% post-test. Of patients originally recommended chemotherapy, 61% were recommended endocrine treatment alone after receiving the Recurrence Score result. For both pN0 and pN1mi patients, post-test recommendations appeared to follow the Recurrence Score result for low and high values. Physicians' confidence improved significantly. These are the first prospective data on the impact of the Oncotype DX assay on adjuvant treatment decisions in France. Using the assay was associated with a significant change in treatment decisions and an overall reduction in chemotherapy use. These data are consistent with those presented from European and non-European studies. ©AlphaMed Press.

This study sought to evaluate whether myeloid-derived suppressor cells (MDSC) could be affected by chemotherapy and correlate with pathologic complete response (pCR) in breast cancer patients receiving neo-adjuvant chemotherapy. Peripheral blood levels of granulocytic (G-MDSC) and monocytic (M-MDSC) MDSC were measured by flow cytometry prior to cycle 1 and 2 of doxorubicin and cyclophosphamide and 1st and last administration of paclitaxel or paclitaxel/anti-HER2 therapy. Of 24 patients, 11, 6 and 7 patients were triple negative, HER2+ and hormone receptor+, respectively. 45.8% had pCR. Mean M-MDSC% were <1. Mean G-MDSC% and 95% confidence intervals were 0.88 (0.23-1.54), 5.07 (2.45-7.69), 9.32 (4.02-14.61) and 1.97 (0.53-3.41) at draws 1-4. The increase in G-MDSC by draw 3 was significant (p < 0.0001) in all breast cancer types. G-MDSC levels at the last draw were numerically lower in patients with pCR (1.15; 95% CI 0.14-2.16) versus patients with no pCR (2.71; 95% CI 0-5.47). There was no significant rise in G-MDSC from draw 1 to 3 in African American patients, and at draw 3 G-MDSC levels were significantly lower in African Americans versus Caucasians (p < 0.05). It was concluded that G-MDSC% increased during doxorubicin and cyclophosphamide therapy, but did not significantly differ between patients based on pathologic complete response.

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

The benefit of adjuvant trastuzumab with chemotherapy is well established for women with higher risk human epidermal growth factor receptor 2-positive (HER2 + ) breast cancer. However, its role in older patients with smaller, node-negative tumors is less clear. We conducted a retrospective, sequential cohort study of this population to describe the impact of trastuzumab on breast cancer outcomes and cardiac safety. Women ≥ 55 years with ≤ 2 cm, node-negative, HER2 + breast cancer were identified and electronic medical records reviewed. A no-trastuzumab cohort of 116 women diagnosed between January 1, 1999 and May 14, 2004 and a trastuzumab cohort of 128 women diagnosed between May 16, 2006 and December 31, 2010 were identified. Overall survival and distant relapse-free survival were estimated by Kaplan-Meier methods. The median ages of the trastuzumab and no-trastuzumab cohorts were 62 and 64 years, respectively. More patients in the trastuzumab cohort had grade III (P = .001), lymphovascular invasion (P = .001), or estrogen receptor-negative (P < .001) cancers. The majority of the trastuzumab cohort received chemotherapy versus one-half of the no-trastuzumab cohort (98% vs. 53%; P < .0001). The median follow-up was 4 versus 9 years in the trastuzumab versus no-trastuzumab cohorts; therefore, outcomes at 4 years are reported. Despite the higher-risk tumor features in the trastuzumab group, the 4-year overall survival was 99% in both cohorts; the distant relapse-free survival was 99% versus 97% in the trastuzumab versus no-trastuzumab cohorts. Four (3.1%; 95% confidence interval, 1.0%-7.8%) women in the trastuzumab cohort and 1 in the no-trastuzumab cohort developed symptomatic heart failure. There were no cardiac-related deaths in either arm. Following adjuvant trastuzumab with chemotherapy, selected older women with small, node-negative, HER2 + breast cancers have excellent disease control. The rate of cardiac events is low.

We report a novel system of organically modified silica nanoparticles (Ormosil) capable of near infrared fluorescence and chemotherapy with adjuvant hyperthermia for image guided cancer therapy. Ormosil nanoparticles were loaded with a chemotherapeutic, Doxorubicin (DOX) and cyanine dye, IR820. Ormosil particles had a mean diameter of 51.2±2.4 nanometers and surface charge of -40.5±0.8mV. DOX was loaded onto Ormosil particles via physical adsorption (FDSIR820) or covalent linkage (CDSIR820) to the silanol groups on the Ormosil surface. Both formulations retained DOX and IR820 over a period of 2 days in aqueous buffer, though CDSIR820 retained more DOX (93.2%) compared to FDSIR820 (77.0%) nanoparticles. Exposure to near infrared laser triggered DOX release from CDSIR820. Uptake of nanoparticles was determined by deconvolution microscopy in ovarian carcinoma cells (Skov-3). CDSIR820 localized in the cell lysosomes whereas cells incubated with FDSIR820 showed DOX fluorescence from the nucleus indicating leakage of DOX from the nanoparticle matrix. FDSIR820 nanoparticles showed severe toxicity in Skov-3 cells whereas CDSIR820 particles had the same cytotoxicity profile as bare (No DOX and IR820) Ormosil particles. Furthermore, exposure of CDSIR820 nanoparticles to Near Infrared laser at 808 nanometers resulted in generation of heat (to 43°C from 37°C) and resulted in enhanced cell killing compared to Free DOX treatment. Bio-distribution studies showed that CDSIR820 nanoparticles were primarily present in the organs of Reticuloendothelial (RES) system. Copyright © 2016 Elsevier B.V. All rights reserved.

The present study analyzed the expression of phosphorylated AMP-activated protein kinase (pAMPK), Fyn kinase, and pyruvate dehydrogenase kinase-1 (PDK-1) and their impact on the survival of patients with resected gastric cancer who received cisplatin-based adjuvant chemotherapy. Korean patients with stage II-IV (M0) gastric adenocarcinoma who underwent a gastrectomy with D2 lymph node resection and received a combination regimen of cisplatin and S-1 were enrolled. Immunohistochemistry was carried out to determine the expression of pAMPK, Fyn kinase, and PDK-1 in operative specimens of gastric cancer. The expression was divided into two groups according to the intensity score (negative: 0 or 1+ and positive: 2+ or 3+). From January 2006 to July 2010, 73 tumor samples obtained from 74 patients were analyzed. Forty patients were included in the pAMPK-positive group, while 33 patients were included in the pAMPK-negative group. Meanwhile, positive Fyn kinase expression was observed in only 10 patients (13.7 %), and there was no or very weak PDK-1 staining. The clinicopathologic characteristics were similar between the two groups according to the expression of pAMPK. With a median follow-up duration of 26.5 months (2.6-73.2), the estimated 3-year relapse-free survival (RFS) and overall survival rates were 55.0 and 78.4 %, respectively. In a multivariate analysis adjusted for age, sex, Lauren classification, and stage, the pAMPK-negative group was significantly associated with improved RFS (Hazard ratio = 0.459, 95 % CI 0.109-0.711, P = 0.043). A low expression of pAMPK was found to be correlated with better RFS in patients with resected gastric cancer treated with adjuvant cisplatin-based chemotherapy.

Summary Background Elderly breast cancer patients are underrepresented in clinical trials and this leads to a lack of knowledge regarding the tolerance and side effects of modern chemotherapy regimens, especially in dose-dense (dd) or dose-intensified combination. Patients and Methods In this analysis, data from 4 German, randomized (neo-)adjuvant trials, including anthracycline-based chemotherapy, were evaluated for toxicity, compliance and feasibility. Patients were grouped according to age. Results Of the 4,775 patients, 73.6% were < 60 years, 15.8% were 60–64 years and 10.6% were > 64 years. The patients’ compliance decreased with increasing age, the rate of therapy discontinuations was 10.3%; 16.0% were > 64 years old (p < 0.001). The rate of dose reductions also increased with increasing age in the docetaxel/doxorubicin/cyclophosphamide (TAC) (p overall = 0.02) and 5-fluorouracil/epirubicin-cyclophosphamide (FE120C) (p overall < 0.001) treatment groups. Neutropenia grade 3 + 4 in patients of > 64 years was 77% in FE120C- compared to 55% in TAC-treated patients (with primary granulocyte colony-stimulating factors (G-CSFs)). The incidence of febrile neutropenia (FN) was lowest in the regimens without additional taxanes. FN in patients aged > 64 years was lower in the FE120C- than in TAC-and dd-doxorubicin/docetaxel-treated groups. Conclusion The range and intensity of toxicity increased with age. Neutropenia did not increase significantly in the dd groups; the highest rate was seen in FE120C-treated patients. FE120C without G-CSFs is not an option in patients older than 64 years.

This study was aimed to investigate the prognostic value of tumor-infiltrating neutrophils (TINs) and to generate a predictive model to refine postoperative risk stratification system for patients with gastric cancer. TIN presents in various malignant tumors, but its clinical significance in gastric cancer remains obscure. The study enrolled 3 independent sets of patients with gastric cancer from 2 institutional medical centers of China. TIN was estimated by immunohistochemical staining of CD66b, and its relationship with clinicopathological features and clinical outcomes were evaluated. Prognostic accuracies were evaluated by C-index and Akaike information criterion. TINs in gastric cancer tissues ranged from 0 to 192 cells/high magnification filed (HPF), 0 to 117 cells/HPF, and 0 to 142 cells/HPF in the training, testing, and validation sets, respectively. TINs were negatively correlated with lymph node classification (P = 0.007, P = 0.041, and P = 0.032, respectively) and tumor stage (P = 0.019, P = 0.013, and P = 0.025, respectively) in the 3 sets. Moreover, multivariate analysis identified TINs and tumor node metastasis (TNM) stage as 2 independent prognostic factors for overall survival. Incorporation of TINs into well-established TNM system generated a predictive model that shows better predictive accuracy for overall survival. More importantly, patients with higher TINs were prone to overall survival benefit from postoperative adjuvant chemotherapy. These results were validated in the independent testing and validation sets. TIN in gastric cancer was identified as an independent prognostic factor, which could be incorporated into standard TNM staging system to refine risk stratification and predict for overall survival benefit from postoperative chemotherapy in patients with gastric cancer.

Use of anthracycline-based chemotherapy in patients with early breast cancer (EBC) has been well-established but is often associated with cardiotoxicity. Based on data suggesting a limited benefit of anthracyclines in human epidermal growth factor receptor 2 (HER2)-negative patients, the Simultaneous Study of Docetaxel Based Anthracycline Free Adjuvant Treatment Evaluation, as well as Life Style Intervention Strategies (SUCCESS) C study randomized patients to either anthracycline-containing or anthracycline-free chemotherapy. Given the proven prognostic value of circulating tumor cells (CTCs) in EBC, we compared the prevalence of CTCs after chemotherapy between both treatment arms for a preliminary efficacy assessment. The SUCCESS C trial (NCT00847444) is an open-label, phase III study randomizing 3547 patients with HER2-negative EBC to either 3 cycles of epirubicin, 5-fluorouracil, and cyclophosphamide followed by 3 cycles of docetaxel (FEC-DOC) or 6 cycles of docetaxel and cyclophosphamide (DOC-C). CTC status was prospectively evaluated in hormone receptor-positive patients at the time of last chemotherapy cycle using the US Food and Drug Administration-approved CellSearch System (Janssen Diagnostics). Data on CTC status were available for 1766 patients. Overall, CTCs were found in 221 (12.5%) patients. Univariate analyses revealed that presence of CTCs at time of last chemotherapy cycle was not significantly associated with tumor or patient characteristics (all P > .1). There was no significant difference with respect to presence of CTCs between patients randomized to FEC-DOC or DOC-C (11.5% vs. 13.6%; P = .18). The comparable prevalence of CTCs at the time of last chemotherapy cycle may indicate that anthracycline-free chemotherapy is equally effective to anthracycline-containing chemotherapy in HER2-negative, hormone receptor-positive EBC. However, efficacy data from the final survival analysis of SUCCESS C have to be awaited to confirm these preliminary

Uterine carcinosarcoma is a rare, aggressive subtype of endometrial cancer. Treatment consists of hysterectomy, bilateral salpingo-oophorectomy, and lymphadenectomy (LND). The survival benefit of LND in relation to adjuvant radio- and/or chemotherapy is unclear. We evaluated the impact of LND on survival in relation to adjuvant therapy in uterine carcinosarcoma. Retrospective data on 1,140 cases were combined from the Netherlands Cancer Registry (NCR) and the nationwide network and registry of histo- and cytopathology in the Netherlands (PALGA). LND was defined as the removal of any nodes. Additionally, cases where 10 nodes or less (LND ≤10) or more than 10 nodes (LND > 10) were removed were analyzed separately. Adjuvant therapy was evaluated as radiotherapy, chemotherapy, or radiochemotherapy. Associations were analyzed by χ2 test, log-rank test, and Cox regression analysis. Overall survival (OS) had improved after total abdominal hysterectomy with bilateral salpingo-oophorectomy with LND > 10 (HR 0.62, 95% CI 0.47-0.83). Adjuvant therapy was related to OS with an HR of 0.64 (95% CI 0.54-0.75) for radiotherapy, an HR of 0.65 (95% CI 0.48-0.88) for chemotherapy, and an HR of 0.25 (95% CI 0.13-0.46) for radiochemotherapy. Additionally, adjuvant treatment was related to OS when lymph nodes were positive (HR 0.22, 95% CI 0.11-0.42), but not when they were negative. LND is related to improved survival when more than 10 nodes are removed. Adjuvant therapy improves survival when LND is omitted, or when nodes are positive. © 2018 S. Karger AG, Basel.

The role of adjuvant chemotherapy (AC) within urothelial carcinoma of the urinary bladder (UCUB) patients after radical cystectomy (RC) is under debate. We assessed contemporary AC utilization rates. We also examined the rates of AC according to patient disease and sociodemographic characteristics. We relied on the SEER-Medicare database for non-organ-confined, muscle-invasive T2 N+ -T4a UCUB patients who underwent RC between 1991 and 2009 without neoadjuvant chemotherapy delivery. Multivariable logistic regression analyses tested predictors of AC use; T-stage, N-stage, year of diagnosis, age, gender, race, radiotherapy (RT) administration, marital urban and socioeconomic status, tumor grade and Charlson Comorbidity Index (CCI). Overall, 2681 patients were identified. Of those, 667 (24.9%) received AC. The rate of AC were 21.4%, 23.5%, 24.6% and 29.9% over time (1991-1999 vs. 2000-2002 vs. 2003-2005 vs. 2006-2009) (P=0.002). In multivariable analyses stages pT2N+ (odds ratio (OR): 4.7; P<0.001) and pT3/4aN+ (OR: 4.0; P<0.001), year of diagnosis (OR: 1.9; P<0.001), RT (OR: 1.7; P<0.001), married status (OR: 1.4; P=0.001) and advanced age (OR: 0.3; P<0.001) were independent predictors of AC. Neither race nor CCI demonstrated significance. In conclusion, we report lower than anticipated overall (24.9%) use of AC. Nonetheless, the rate increased from 13.6% (1991) to 24.1% (2009). Presence of lymph node invasion at RC regardless of T2 or T3/4a stage was the most important variable that increased AC use. Older and unmarried individuals were less likely to receive AC. AC rates were higher in T2N+ UCUB patients than in T3-T4a individuals.

Malignant pleural mesothelioma (MPM) is an aggressive neoplasia. Multidisciplinary treatments, including the association of induction and/or adjuvant therapeutic regimens with surgery, have been reported to give encouraging results. Current therapeutic options are not well standardized yet, especially regarding the best association between surgery and medical treatments. The present review aims to assess safety, efficacy and outcomes of different therapies for MPM. Areas covered: This article focuses on the multimodality treatment of mesothelioma. A systematic review was performed by using electronic databases to identify studies that considered induction and adjuvant approaches in MPM therapy in a multidisciplinary setting, including surgery. Endpoints included overall survival, disease free survival, disease recurrence, and complications. Expert commentary: This systematic review offers a comprehensive view of current multidisciplinary therapeutic strategies for MPM, suggesting that multimodality therapy offers acceptable outcomes with better results reported for trimodality approaches. Individualization of care for each patient is fundamental in choosing the most appropriate treatment. The growing complexity of treatment protocols mandates that MPM patients be referred to specialized Centers, in which every component of the interdisciplinary team can provide the necessary expertise and quality of care.

Docetaxel as adjuvant and neoadjuvant treatment for patients with breast cancer.

Developments in the role of adjuvant and neoadjuvant chemotherapy for the treatment of patients with breast cancer have focused on the taxes, in particular, docetaxel. This paper discusses the rationale for the introduction of docetaxel into the management of patients following surgery and also its role in those patients with locally-advanced disease, focussing on key clinical trials. The addition of docetaxel to standard adjuvant chemotherapeutic regimens does seem to result in an increased survival in some patients with early-stage disease. In the neoadjuvant setting, the addition of docetaxel to standard regimens does increase pathological response rates, which is a surrogate marker of eventual outcome.

Decisions regarding adjuvant therapy in patients with stage II colorectal cancer (CRC) have been among the most challenging and controversial in oncology over the past 20 years. To develop robust combinatory cancer hallmark-based gene signature sets (CSS sets) that more accurately predict prognosis and identify a subset of patients with stage II CRC who could gain survival benefits from adjuvant chemotherapy. Thirteen retrospective studies of patients with stage II CRC who had clinical follow-up and adjuvant chemotherapy were analyzed. Respective totals of 162 and 843 patients from 2 and 11 independent cohorts were used as the discovery and validation cohorts, respectively. A total of 1005 patients with stage II CRC were included in the 13 cohorts. Among them, 84 of 416 patients in 3 independent cohorts received fluorouracil-based adjuvant chemotherapy. Identification of CSS sets to predict relapse-free survival and identify a subset of patients with stage II CRC who could gain substantial survival benefits from fluorouracil-based adjuvant chemotherapy. Eight cancer hallmark-based gene signatures (30 genes each) were identified and used to construct CSS sets for determining prognosis. The CSS sets were validated in 11 independent cohorts of 767 patients with stage II CRC who did not receive adjuvant chemotherapy. The CSS sets accurately stratified patients into low-, intermediate-, and high-risk groups. Five-year relapse-free survival rates were 94%, 78%, and 45%, respectively, representing 60%, 28%, and 12% of patients with stage II disease. The 416 patients with CSS set-defined high-risk stage II CRC who received fluorouracil-based adjuvant chemotherapy showed a substantial gain in survival benefits from the treatment (ie, recurrence reduced by 30%-40% in 5 years). The CSS sets substantially outperformed other prognostic predictors of stage 2 CRC. They are more accurate and robust for prognostic predictions and facilitate the identification of patients with stage

Ginger supplementation could be an effective adjuvant treatment for chemotherapy-induced nausea (CIN). The aim of this clinical trial was to address significant methodological limitations in previous trials. Patients (N = 51) were randomly allocated to receive either 1.2 g of standardised ginger extract or placebo per day, in addition to standard anti-emetic therapy, during the first three cycles of chemotherapy. The primary outcome was CIN-related quality of life (QoL) measured with the Functional Living Index- Emesis (FLIE) questionnaire. Secondary outcomes included acute and delayed nausea, vomiting, and retching as well as cancer-related fatigue, nutritional status, and CIN and vomiting-specific prognostic factors. Over three consecutive chemotherapy cycles, nausea was more prevalent than vomiting (47% vs. 12%). In chemotherapy Cycle 1, intervention participants reported significantly better QoL related to CIN ( p = 0.029), chemotherapy-induced nausea and vomiting (CINV)-related QoL ( p = 0.043), global QoL ( p = 0.015) and less fatigue ( p = 0.006) than placebo participants. There were no significant results in Cycle 2. In Cycle 3, global QoL ( p = 0.040) and fatigue ( p = 0.013) were significantly better in the intervention group compared to placebo. This trial suggests adjuvant ginger supplementation is associated with better chemotherapy-induced nausea-related quality of life and less cancer-related fatigue, with no difference in adverse effects compared to placebo.

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

Patients with isolated locoregional recurrences (ILRR) of breast cancer have a high risk of distant metastasis and death from breast cancer. We aimed to establish whether adjuvant chemotherapy improves the outcome of such patients. The CALOR trial was a pragmatic, open-label, randomised trial that accrued patients with histologically proven and completely excised ILRR after unilateral breast cancer who had undergone a mastectomy or lumpectomy with clear surgical margins. Eligible patients were enrolled from hospitals worldwide and were centrally randomised (1:1) to chemotherapy (type selected by the investigator; multidrug for at least four courses recommended) or no chemotherapy, using permuted blocks, and stratified by previous chemotherapy, oestrogen-receptor and progesterone-receptor status, and location of ILRR. Patients with oestrogen-receptor-positive ILRR received adjuvant endocrine therapy, radiation therapy was mandated for patients with microscopically involved surgical margins, and anti-HER2 therapy was optional. The primary endpoint was disease-free survival. All analyses were by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00074152. From Aug 22, 2003, to Jan 31, 2010, 85 patients were randomly assigned to receive chemotherapy and 77 were assigned to no chemotherapy. At a median follow-up of 4·9 years (IQR 3·6-6 ·0), 24 (28%) patients had disease-free survival events in the chemotherapy group compared with 34 (44%) in the no chemotherapy group. 5-year disease-free survival was 69% (95% CI 56-79) with chemotherapy versus 57% (44-67) without chemotherapy (hazard ratio 0·59 [95% CI 0·35-0·99]; p=0·046). Adjuvant chemotherapy was significantly more effective for women with oestrogen-receptor-negative ILRR (pinteraction=0·046), but analyses of disease-free survival according to the oestrogen-receptor status of the primary tumour were not statistically significant (pinteraction=0·43).

For more than three decades, postoperative chemotherapy-initially fluoropyrimidines and more recently combinations with oxaliplatin-has reduced the risk of tumor recurrence and improved survival for patients with resected colon cancer. Although universally recommended for patients with stage III disease, there is no consensus about the survival benefit of postoperative chemotherapy in stage II colon cancer. The most recent adjuvant clinical trials have not shown any value for adding targeted agents, namely bevacizumab and cetuximab, to standard chemotherapies in stage III disease, despite improved outcomes in the metastatic setting. However, biomarker analyses of multiple studies strongly support the feasibility of refining risk stratification in colon cancer by factoring in molecular characteristics with pathologic tumor staging. In stage II disease, for example, microsatellite instability supports observation after surgery. Furthermore, the value of BRAF or KRAS mutations as additional risk factors in stage III disease is greater when microsatellite status and tumor location are taken into account. Validated predictive markers of adjuvant chemotherapy benefit for stage II or III colon cancer are lacking, but intensive research is ongoing. Recent advances in understanding the biologic hallmarks and drivers of early-stage disease as well as the micrometastatic environment are expected to translate into therapeutic strategies tailored to select patients. This review focuses on the pathologic, molecular, and gene expression characterizations of early-stage colon cancer; new insights into prognostication; and emerging predictive biomarkers that could ultimately help define the optimal adjuvant treatments for patients in routine clinical practice. © 2015 by American Society of Clinical Oncology.

The role of adjuvant chemotherapy for patients with rectal cancer is controversial, especially when used after preoperative chemoradiotherapy. Fluoropyrimidine-based adjuvant chemotherapy, including fluorouracil and leucovorin, has been widely used; however, the addition of oxaliplatin to fluorouracil and leucovorin (FOLFOX), a standard adjuvant regimen for colon cancer, has not been tested in rectal cancer. We aimed to compare the efficacy and safety of adjuvant fluorouracil and leucovorin with that of FOLFOX in patients with locally advanced rectal cancer after preoperative chemoradiotherapy. In this open-label, multicentre, phase 2, randomised trial, patients with postoperative pathological stage II (ypT3-4N0) or III (ypTanyN1-2) rectal cancer after preoperative fluoropyrimidine-based chemoradiotherapy and total mesorectal excision were recruited and randomly assigned (1:1) via a web-based software platform to receive adjuvant chemotherapy with either four cycles of fluorouracil and leucovorin (fluorouracil 380 mg/m(2) and leucovorin 20 mg/m(2) on days 1-5, every 4 weeks) or eight cycles of FOLFOX (oxaliplatin 85 mg/m(2), leucovorin 200 mg/m(2), and fluorouracil bolus 400 mg/m(2) on day 1, and fluorouracil infusion 2400 mg/m(2) for 46 h, every 2 weeks). Stratification factors were pathological stage (II vs III) and centre. Neither patients nor investigators were masked to group assignment. The primary endpoint was 3-year disease-free survival, analysed by intention to treat.

Retinoblastoma can extend beyond the structures of the eye, where cells can enter the bloodstream and cause metastases. Various types of protocols for adjuvant treatment risk-adapted according to histopathological risk factors are used worldwide. Between 1997 and 2009, 420 children were diagnosed with retinoblastoma at the German Retinoblastoma Referral Centre and risk factors were assessed. Patients with post-laminar optic nerve infiltration or choroid or minor scleral invasion received six courses of adjuvant chemotherapy using vincristine, etoposide, carboplatin and cyclophosphamide (group 1). Patients with microscopic extension beyond the sclera to the resection margin of the optic nerve or potential spread due to vitrectomy received chemotherapy plus orbital radiotherapy (group 2). Neoadjuvant chemotherapy was performed in patients with local extraocular invasion detected on MRI. Following this protocol, 42 of the 420 patients and 21 referred from other centres showed high-risk histopathological factors qualifying for adjuvant therapy (57 in group 1 and 6 in group 2). Seven of the 63 patients received neoadjuvant and adjuvant treatment. During a mean follow-up of 5.8 (range 0.4-15.4) years, one of six patients in group 2 developed metastases and died. No patients died from toxicity. The 5-year overall survival was 100% for group 1 and 80% for group 2. This retrospective single-site study reveals a 10% incidence of high-risk features in children with retinoblastoma diagnosed at the German Retinoblastoma Referral Centre. Overall survival rates of 98.3% underline the safety of this adjuvant chemotherapy protocol and its efficiency in preventing metastasis. Published by the BMJ Publishing Group Limited.

Multidisciplinary team (MDT) meetings are used to optimise expert decision-making about treatment options, but such expertise is not digitally transferable between centres. To help standardise medical decision-making, we developed a machine learning model designed to predict MDT decisions about adjuvant breast cancer treatments. We analysed MDT decisions regarding adjuvant systemic therapy for 1065 breast cancer cases over eight years. Machine learning classifiers with and without bootstrap aggregation were correlated with MDT decisions (recommended, not recommended, or discussable) regarding adjuvant cytotoxic, endocrine and biologic/targeted therapies, then tested for predictability using stratified ten-fold cross-validations. The predictions so derived were duly compared with those based on published (ESMO and NCCN) cancer guidelines. Machine learning more accurately predicted adjuvant chemotherapy MDT decisions than did simple application of guidelines. No differences were found between MDT- vs. ESMO/NCCN- based decisions to prescribe either adjuvant endocrine (97%, p = 0.44/0.74) or biologic/targeted therapies (98%, p = 0.82/0.59). In contrast, significant discrepancies were evident between MDT- and guideline-based decisions to prescribe chemotherapy (87%, p < 0.01, representing 43% and 53% variations from ESMO/NCCN guidelines, respectively). Using ten-fold cross-validation, the best classifiers achieved areas under the receiver operating characteristic curve (AUC) of 0.940 for chemotherapy (95% C.I., 0.922-0.958), 0.899 for the endocrine therapy (95% C.I., 0.880-0.918), and 0.977 for trastuzumab therapy (95% C.I., 0.955-0.999) respectively. Overall, bootstrap aggregated classifiers performed better among all evaluated machine learning models. A machine learning approach based on clinicopathologic characteristics can predict MDT decisions about adjuvant breast cancer drug therapies. The discrepancy between MDT- and guideline-based decisions

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

Breast cancer patients undergoing adjuvant chemotherapy often develop fatigue from their treatment that may persist for months. While the positive effects of physical activity in cancer patients are increasingly recognized, the impact of obesity on chemotherapy-induced fatigue has not been well studied. Female age 35-75 years with stage I-III breast cancer receiving adjuvant chemotherapy were enrolled in an IRB-approved study. Patient fatigue was self-reported using a 14-question fatigue symptom inventory. Patients were queried about fatigue and their level of exercise before, during, and after completion of chemotherapy. BMI was measured prior to their first cycle of chemotherapy. Of the 47 evaluable patients, 37 reported performing exercise on a regular basis. Following chemotherapy, 53 % of the exercise group and 80 % of the non-exercise group displayed a worsening of their FS. In patients with a BMI < 25, the fatigue score (FS) after chemotherapy was 27.6 in the exercise group versus 40.5 in the non-exercise group. In patients with a BMI > 25, the FS after chemotherapy was 25.96 in the exercise group versus 32.6 in the non-exercise group. Our study indicates a trend towards fatigue reduction with exercise even in patients who are overweight. Thus, an elevated BMI at diagnosis does not preclude a breast cancer patient from experiencing the same positive effects from exercise on chemotherapy-related fatigue as patients with normal BMIs. This indicates an important role of physicians in the primary care setting to encourage patients to initiate physical activity when offering cancer-screening services.

Premenopausal women undergoing chemotherapy are at high risk for premature ovarian failure and its long-term consequences. Data on potential markers to evaluate ovarian reserve pre- and posttreatment are limited. Anti-Müllerian hormone (AMH) known for ovarian reserve in reproductive medicine could be a surrogate marker and was assessed in premenopausal breast cancer patients of the SUCCESS A study (EUDRA-CT no. 2005-000490-21). We identified 170 premenopausal patients, age ≤ 40 years at trial entry, who received FEC-Doc as taxane-anthracylince based chemotherapy. Blood samples were taken at three time points: Before, four weeks after and two years after adjuvant chemotherapy. Serum AMH-levels were evaluated in a central laboratory by a quantitative immunoassay AMH Gen II ELISA (Beckman Coulter, Brea, USA). Median age was 36 years (21-40 years). Median serum AMH-level before chemotherapy was 1.37 ng/ml (range < 0.1-11.3 ng/ml). Four weeks after chemotherapy AMH-levels dropped in 98.6% of the patients to <0.1 ng/ml (range < 0.1-0.21 ng/ml). After two years, 73.3% (n = 101) showed no evidence of ovarian function recovery (AMH <0.1 ng/ml, range < 0.1-3.9 ng/ml). Permanent chemotherapy induced amenorrhea occurred only in 50.6% of the patients. In this analysis, premenopausal patients showed a high rate of ovarian impairment reflected by low AMH-levels after chemotherapy. Copyright © 2017 Elsevier Ltd. All rights reserved.

Persistent fatigue and cognitive dysfunction are poorly understood potential long-term effects of adjuvant chemotherapy. In this pilot study, we assessed the value of electroencephalogram (EEG) power measurements as a means to evaluate physical and mental fatigue associated with chemotherapy. Women planning to undergo adjuvant chemotherapy for breast cancer and healthy controls underwent neurophysiologic assessments at baseline, during the time of chemotherapy treatment, and at 1 year. Repeated measures analysis of variance was used to analyze the data. Compared with controls, patients reported more subjective fatigue at baseline that increased during chemotherapy and did not entirely resolve by 1 year. Performance on endurance testing was similar in patients versus controls at all time points; however, values of EEG power increased after a physical task in patients during chemotherapy but not controls. Compared with controls, subjective mental fatigue was similar for patients at baseline and 1 year but worsened during chemotherapy. Patients performed similarly to controls on formal cognitive testing at all time points, but EEG activity after the cognitive task was increased in patients only during chemotherapy. EEG power measurement has the potential to provide a sensitive neurophysiologic correlate of cancer treatment-related fatigue and cognitive dysfunction.

Following inguinal orchidectomy, management options for patients with stage I seminoma include initial surveillance or treatment with adjuvant radiotherapy or chemotherapy. The anticipated relapse rate for patients followed by surveillance alone is ∼15%, with adjuvant treatment this risk is reduced to ∼4%-5% at 5 years. After carboplatin treatment, follow-up strategies vary and there are no validated, predictive markers of relapse. We conducted a retrospective analysis of all patients presenting with stage I seminoma who received a single cycle of adjuvant carboplatin in South Central England between 1996 and 2013. We report on outcome and the results of univariate and multivariate analysis evaluating possible risk factors for post carboplatin relapse. A total of 517 eligible patients were identified. All underwent nuclear medicine estimation of glomerular filtration rate before treatment with carboplatin (dosed at area under the curve × 7). With a median follow-up of 47.2 months (range 0.4-214 months), 21/517 patients have relapsed resulting in a 5-year estimated relapse-free survival of 95.0% (95% confidence interval 92.8% to 97.3%). Median time to relapse was 22.7 months (range 12.5-109.5 months). Relapse beyond 3 years was rare (4/517; 0.8%). Twenty of 21 (95%) relapsed patients had retroperitoneal lymph node metastases. The majority (16/21; 76%) of patients had elevated tumour markers at relapse. Twenty of 517 (3.9%) patients developed a new contralateral testicular germ-cell cancer. There were no seminoma-related deaths. Tumour size was the only variable significantly associated with an increased risk of relapse. Overall results for this large cohort of patients confirm an excellent prognosis for these patients with outcomes equivalent to those seen in prospective clinical trials. Increasing tumour size alone appears to be associated with an increased risk of post chemotherapy relapse. © The Author 2015. Published by Oxford University Press on behalf of

Neoadjuvant chemotherapy (NAC) increases breast conservation rates in patients with resectable breast cancer at the associated cost of higher locoregional recurrence rates; however, the magnitude of the survival benefits of NAC for these patients remains undefined. Therefore, we aimed to clarify the survival benefit of NAC versus postoperative chemotherapy by conducting an updated meta-analysis of randomized clinical trials (RCTs). The authors searched the Cochrane Library, PubMed, Embase, Web of Science, Chinese biomedical literature database, and Chinese Scientific Journals full-text database from their inception to December 2016. The authors identified relevant RCTs that compared NAC with postoperative chemotherapy in the treatment of operable breast cancer. The main endpoints were overall survival (OS) and recurrence-free survival (RFS). A total of 21 citations representing 16 unique studies were eligible. There were 787 deaths among 2794 patients assigned to NAC groups and 816 deaths among 2799 patients assigned to adjuvant chemotherapy groups. A meta-analysis of data indicated that there was no significant benefit in terms of OS ([hazard ratio [HR] = 1.03, 95% confidence interval [CI]: 0.94-1.13, P = .51) and RFS (HR = 1.01, 95% CI: 0.93-1.10, P = .80) between the NAC and postoperative chemotherapy groups. The pooled HR estimate for OS was not influenced by NAC cycles, the total number of chemotherapy cycles, administration of tamoxifen, administration of adjuvant chemotherapy, or type of NAC regimen. Subgroup analysis showed that the pooled HR estimate for RFS was influenced by anthracycline-containing regimens. Patients with a pathological complete response had superior survival outcomes compared with patients who had residual disease. The survival benefits for patients with operable breast cancer who received either NAC or adjuvant chemotherapy based on anthracycline regimens were comparable.

There is a debate regarding the management of ovarian immature teratomas (ITs). In adult women, postoperative chemotherapy is standard except for stage I, grade 1 disease, whereas surgery alone is standard in pediatric patients. To determine the role of chemotherapy, a pooled analysis of pediatric and adult clinical trials was conducted. Data from 7 pediatric trials and 2 adult trials were merged in the Malignant Germ Cell International Collaborative data set. Four trials included patients with newly diagnosed pure ovarian ITs and were selected (Pediatric Oncology Group/Children's Cancer Group Intergroup Study (INT 0106), Second UKCCSG Germ Cell Tumor Study (GC2), Gynecologic Oncology Group (GOG 0078 and GOG 0090). Adult and pediatric trials were analyzed separately. The primary outcome measures were event-free survival (EFS) and overall survival (OS). One hundred seventy-nine patients were included (98 pediatric patients and 81 adult patients). Ninety pediatric patients were treated with surgery alone, whereas all adult patients received chemotherapy. The 5-year EFS and OS were 91% and 99%, respectively, for the pediatric cohort and 87% and 93%, respectively, for the adults. There were no relapses in grade 1 patients, regardless of the stage or age. Only 1 adult patient with a grade 2 IT relapsed. Among grade 3 patients, the 5-year EFS was 0.92 (0.72-0.98) for stage I/II and 0.52 (0.22-0.75) for stage III in the pediatric cohort (P = .005) and 0.91 (0.69-0.98) for stage I/II and 0.65 (0.39-0.83) for stage III/IV in the adult cohort (P = .01). Postoperative chemotherapy did not decrease relapses in the pediatric cohort. The grade was the most important risk factor for relapse in ovarian ITs. Among grade 3 patients, the stage was significantly associated with relapse. Adjuvant chemotherapy did not decrease relapses in the pediatric cohort; its role in adults remains unresolved.

Triplet antiemetic therapy with neurokinin 1 receptor blocker, 5-hydroxytryptamine receptor blocker and steroids is commonly used in patients who are highly emetic after chemotherapy. However, an alternative antiemetic therapy for patients who are resistant to triplet antiemetic therapy is not established. Olanzapine is recommended in the guidelines as an optional antiemetic drug. However, the effectiveness of adding olanzapine to triplet antiemetic therapy is unknown. In this study, the effectiveness and safety of adding olanzapine to triplet antiemetic therapy with aprepitant, palonosetron and dexamethasone as highly emetic anthracycline-containing adjuvant chemotherapy for primary breast cancer patients were prospectively investigated. Forty-five patients with breast cancer who experienced >Grade 1 nausea or any vomiting after the first cycle of chemotherapy using both epirubicin and cyclophosphamide were included. Low-dose olanzapine (2.5 mg/day) was administered orally from the first day of chemotherapy for 4 days, and the number of episodes of vomiting, scale of nausea, dietary intake and somnolence were compared with the symptoms after the first cycle. As the primary endpoint, the nausea grade was significantly improved by adding olanzapine (P < 0.05). As the secondary endpoints, mean nausea scale (3.2→1.9, Day 1; 3→1.3-1, Days 2-6) and dietary intake (33.6→53.8%, Day 1; 42.0→60.7-78.1%, Days 2-6) were improved by adding olanzapine. Only four patients withdrew due to somnolence and/or dizziness. This study demonstrated the effectiveness and tolerability of adding low-dose olanzapine for patients with insufficient nausea relief with triplet antiemetic therapy consisting of palonosetron, steroid and aprepitant.

The aim of the present study was to analyze the effect of subtype and body mass index (BMI) on neo-adjuvant chemotherapy (NAC) and postoperative prognosis. Two-hundred and forty nine patients who underwent surgery after NAC were included. A multivariate analysis and survival analysis were used to clarify the relationship between BMI, subtype, and NAC. In the logistic regression model, the pCR rate had a significant relationship with the subtype and tumor stage. In the non-pCR group, more overweight patients had significantly a worse disease-free survival (DFS) compared to normal range patients (Log lank test, p < 0.05). In the Cox proportional hazards model, subtype and tumor stage were significantly associated with decreased DFS. In conclusion, patients with the ER (+), HER (-) type and a high BMI had a high risk for recurrence when they achieved non-pCR after NAC. Copyright © 2014 Elsevier Ltd. All rights reserved.

The optimal adjuvant treatment for cT1-2 N0 esophageal cancer patients found to have pathologic nodal involvement after an upfront operation is unclear. This study investigated the effects of postoperative chemotherapy and chemoradiation therapy on overall survival in cT1-2 N0 patients with incidental pN + disease stratified by margin status. We identified cT1-2 N0 M0 esophageal carcinoma patients from 2004 to 2012 from the National Cancer Data Base. Patients were categorized as having received surgical resection alone, surgical resection followed by chemotherapy (S+CT), and surgical resection followed by concurrent chemoradiation therapy (S+CRT). Subset analyses were conducted on margin-negative and margin-positive patients. Overall survival was compared by Kaplan-Meier estimation, the log-rank test, and multivariable Cox regression analysis. Among 443 patients, 52.6% received surgical resection alone, 18.7% received S+CT, and 28.6% received S+CRT. Significantly more adenocarcinoma patients received adjuvant treatment (50.8%) than squamous cell carcinoma patients (27.7%, p = 0.001). On multivariable analysis, S+CT (hazard ratio, 0.64; 95% confidence interval, 0.45 to 0.91; p = 0.014) and S+CRT (hazard ratio, 0.73; 95% confidence interval,. 0.55 to 0.98; p = 0.038) both were associated with significantly increased overall survival. These findings persisted among margin-negative patients. However, in margin-positive patients, S+CRT (hazard ratio, 0.29; p = 0.002) was the only treatment arm that was associated with significantly improved survival compared with surgical resection alone. Among cT1-2 N0 pN + esophageal cancer patients, adjuvant chemotherapy may be sufficient for margin-negative patients, whereas adjuvant chemoradiation therapy appears necessary for margin-positive patients. Further prospective studies are needed to confirm the results. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

The latest studies suggest that prophylactic chemotherapy or adjuvant chemotherapy for early stage breast cancer may increase the leukemia risk in patients. For patients with a low risk for breast cancer recurrence, physicians who make the choice for adjuvant therapy should consider the risk of its long-term side effects. Is the occurrence of lymphatic system cancer and leukemia after breast cancer treatment associated with chemotherapy? Can these types of leukemia be classified as therapy-related leukaemias? We believe that there may be correlations between any diseases, butwe cannot rush to conclusions or dismiss a correlation because we understand little about the diseases themselves.In this paper, we present a case of secondary diffuse large B-cell lymphoma and leukemia in patients after breast cancer chemotherapy, it is undeniable that this is a special event. For two distinct tumouroccurrences at different times, we cannot give a clear explanation because of thechanges in the genes that might link them together and we hope to attract the attention of other clinicians.

Purpose: To analyze the efficacy, toxicity, and pattern of relapse after adjuvant cisplatin-based chemotherapy followed by three-dimensional irradiation and concomitant LV5FU2 chemotherapy (high-dose leucovorin and 5-fluorouracil bolus plus continuous infusion) in the treatment of completely resected high-risk gastric cancer. Methods and Materials: This was a retrospective analysis of 52 patients with high-risk gastric cancer initially treated by total/partial gastrectomy and lymphadenectomy between January 2002 and June 2007. Median age was 54 years (range, 36-75 years). Postoperative treatment consisted of 5-fluorouracil and cisplatin chemotherapy. Adjuvant chemotherapy was followed by three-dimensional conformal radiotherapy in the tumor bed and regional lymph nodes atmore » 4500 cGy/25 fractions in association with concomitant chemotherapy. Concomitant chemotherapy consisted of a 2-h infusion of leucovorin (200 mg/m Superscript-Two ) followed by a bolus of 5-fluorouracil (400 mg/m Superscript-Two ) and then a 44-h continuous infusion of 5-fluorouracil (2400-3600 mg/m Superscript-Two ) given every 14 days, for three cycles (LV5FU2 protocol). Results: Five-year overall and disease-free survival were 50% and 48%, respectively. Distant metastases and peritoneal spread were the most frequent sites of relapse (37% each). After multivariate analysis, only pathologic nodal status was significantly associated with disease-free and overall survival. Acute toxicities were essentially gastrointestinal and hematologic. One myocardial infarction and one pulmonary embolism were also reported. Eighteen patients had a radiotherapy program interruption because of acute toxicity. All patients but 2 have completed radiotherapy. Conclusion: Postoperative cisplatin-based chemotherapy followed by conformal radiotherapy in association with concurrent 5-fluorouracil seemed to be feasible and resulted in successful locoregional control.« less

This study aimed to analyze the occurrence of skin toxicity caused by drugs used in the protocol of neoadjuvant and adjuvant chemotherapy among women with breast cancer. Patient records of 72 women who were subject to this therapy between 2003 and 2006 were assessed. Of the 558 cycles of chemotherapy, 152 adverse events were registered. There were 37 registrations of dermatological toxicity, of those, 20 were extravasations that affected 17 women. Nine reports of hardened local injury, local fibrosis, pain, and hyperemia were registered during neoadjuvancy. In adjuvancy, among the 11 extravasations registered there were reports of hardened local injury, fibrosis and local pain. Lack of follow-up records for both periods was observed. Registration of the events and reports by the nursing team are essential to monitor the sites of venous puncture during the chemotherapy treatment, besides measuring and making a photographic record of the site.

To compare the efficacy and tolerance of adjuvant chemotherapy and radiotherapy delivered in sequential (chemotherapy followed by radiation) versus "sandwich" fashion (chemotherapy, interval radiation, and remaining chemotherapy) after surgery in patients with FIGO stage III uterine endometrioid adenocarcinoma. From 2004 to 2011, we identified 51 patients treated at our institution fitting the above criteria. All patients received surgical staging followed by adjuvant chemoradiation (external-beam radiation therapy (EBRT) with or without high-dose rate (HDR) vaginal brachytherapy (VB)). Of these, 73% and 27% of patients received their adjuvant therapy in sequential and sandwich fashion, respectively. There were no significant differences in clinical or pathologic factors between patients treated with either regimen. Thirty-nine (76%) patients had stage IIIC disease. The majority of patients received 6 cycles of paclitaxel with carboplatin or cisplatin. Median EBRT dose was 45 Gy and 54% of patients received HDR VB boost (median dose 21 Gy). There were no significant differences in the estimated 5-year overall survival, local progression-free survival, and distant metastasis-free survival between the sequential and sandwich groups: 87% vs. 77% (p=0.37), 89% vs. 100% (p=0.21), and 78% vs. 85% (p=0.79), respectively. No grade 3-4 genitourinary or gastrointestinal toxicities were reported in either group. There was a trend towards higher incidence of grade 3-4 hematologic toxicity in the sandwich group. Adjuvant chemoradiation for FIGO stage III endometrioid uterine cancer given in either sequential or sandwich fashion appears to offer equally excellent early clinical outcomes and acceptably low toxicity.

Purpose: To analyze the effect of adjuvant chemoradiotherapy on gallbladder carcinoma. Methods and Materials: We retrospectively reviewed the records from consecutive patients who underwent R0 resection of gallbladder carcinoma between January 1, 1985, and December 31, 2004. Patients had either Stage I (T1-T2N0M0) or Stage II (T3N0M0 or T1-T3N1M0) disease. Patients undergoing adjuvant therapy received 5-fluorouracil chemotherapy concurrently with radiotherapy (median dosage, 50.4 Gy in 28 fractions). Adverse prognostic factors and the effect of adjuvant treatment on overall survival (OS) were evaluated. Results: A total of 73 patients were included in the analysis; of these, 25 received adjuvant chemoradiotherapy. Onmore » univariate analysis, no adverse prognostic factors for OS reached statistical significance, but trends were noted for Stage N1 vs. N0 (p = .06), Nx vs. N0 (p = .09), Stage T3 vs. T1-T2 (p = .06), and histologic findings other than adenocarcinoma (p = .13). The median OS for patients receiving adjuvant chemoradiotherapy vs. surgery alone was 4.8 years and 4.2 years, respectively (log-rank test, p = .56). However, a significantly greater percentage of patients receiving adjuvant chemoradiotherapy had Stage II disease (p <.001). In the multivariate Cox model, increasing T and N category and histologic findings other than adenocarcinoma were significant predictors of decreased OS. Additionally, adjuvant chemoradiotherapy was a significant predictor of improved OS after adjusting for these prognostic factors (hazard ratio for death, 0.3; 95% confidence interval, 0.13-0.69; p = .004). Conclusion: After adjusting for the stage parameters and histologic findings, our data suggest that adjuvant chemoradiotherapy might improve OS for patients with gallbladder cancer.« less

Triple negative breast cancer (TNBC) accounts for 15%-20% of all breast cancer, and is still defined as what it is not. Currently, TNBC is the only type of breast cancer for which there are no approved targeted therapies and maximum tolerated dose chemotherapy with taxanes and anthracycline-containing regimens is still the standard of care in both the neoadjuvant and adjuvant settings. In the last years, metronomic chemotherapy (MC) is being explored as an alternative to improve outcomes in TNBC. In the neoadjuvant setting, purely metronomic and hybrid approaches have been developed with the objective of increasing complete pathologic response (pCR) and prolonging disease free survival. These regimens proved to be very effective achieving pCR rates between 47%-60%, but at the cost of great toxicity. In the adjuvant setting, MC is used to intensify adjuvant chemotherapy and, more promisingly, as maintenance therapy for high-risk patients, especially those with no pCR after neoadjuvant chemotherapy. Considering the dismal prognosis of TNBC, any strategy that potentially improves outcomes, specially being the oral agents broadly available and inexpensive, should be considered and certainly warrants further exploration. Finally, the benefit of MC needs to be validated in properly designed clinical trials were the selection of the population is the key. PMID:29291168

Potential Proinvasive or Metastatic Effects of Preclinical Antiangiogenic Therapy Are Prevented by Concurrent Chemotherapy.

To resolve a controversy involving the therapeutic impact of antiangiogenic drugs and particularly antibodies targeting the VEGF pathway, namely, a body of preclinical mouse therapy studies showing such drugs can promote invasion and/or distant metastasis when used as monotherapies. In contrast, clinical studies have not shown such promalignancy effects. However, most such clinical studies have involved patients also treated with concurrent chemotherapy highlighting the possibility that chemotherapy may prevent any potential promalignancy effect caused by an antiangiogenic drug treatment. The impact of antiangiogenic therapy using DC101, an antibody targeting mouse VEGFR-2 with or without concurrent chemotherapy was assessed in multiple human breast cancer xenograft models, where impact on orthotopic primary tumors was evaluated. Metastasis was also assessed during adjuvant and neoadjuvant plus adjuvant therapy, after surgical resection of primary tumors, with the same combination therapies. Antiangiogenic therapy, while blunting tumor volume growth, was found to increase local invasion in multiple primary tumor models, including a patient-derived xenograft, but this effect was blocked by concurrent chemotherapy. Similarly, the combination of paclitaxel with DC101 caused a marked reduction of micro- or macrometastatic disease in contrast to DC101 monotherapy, which was associated with small increases in metastatic disease. Conventional wisdom is that targeted biologic antiangiogenic agents such as bevacizumab when used with chemotherapy increase the efficacy of the chemotherapy treatment. Our results suggest the reverse may be true as well-chemotherapy may improve the impact of antiangiogenic drug treatment and, as a result, overall efficacy.

Initial randomised studies of chemotherapy and endocrine therapy showed that systemic treatments had a substantial impact on the survival of women with early breast cancer. The original assumption was that the efficacy of these treatments was limited to those patients presenting with more adverse prognostic features. Subsequently, meta-analyses of randomised trials revealed that the benefits of chemotherapy and endocrine therapy are not mutually exclusive and extend to all the prognostic subgroups. However, the absolute benefit varies according to baseline characteristics such as tumour stage and other biological factors. Over the last 10 years, considerable progress has been made with the introduction of new drugs into the adjuvant and neoadjuvant treatment of women with breast cancer. Taxanes and third-generation aromatase inhibitors are providing proof of additional benefits compared with standard reference treatments. In parallel, research on the biology of breast cancer is establishing novel prognostic and predictive factors, which may allow better treatment tailoring. Currently, however, women with early breast cancer and their doctors face the difficult task of making therapeutic decisions often based on early results from positive studies. In a disease where follow up is crucial to fully assess the benefit and long-term toxicities of an intervention, current knowledge leaves unanswered questions that generate debate and controversy. This review will summarise recent results from randomised trials of adjuvant and neoadjuvant therapy in women with early breast cancer and focus on the current controversies.

Anthracycline- and taxane-based three-drug chemotherapy regimens have proven benefit as adjuvant therapy for early-stage breast cancer. This trial (NSABP B-38; Combination Chemotherapy in Treating Women Who Have Undergone Surgery for Node-Positive Breast Cancer) asked whether the incorporation of a fourth drug could improve outcomes relative to two standard regimens and provided a direct comparison of those two regimens. We randomly assigned 4,894 women with node-positive early-stage breast cancer to six cycles of docetaxel, doxorubicin, and cyclophosphamide (TAC), four cycles of dose-dense (DD) doxorubicin and cyclophosphamide followed by four cycles of DD paclitaxel (P; DD AC→P), or DD AC→P with four cycles of gemcitabine (G) added to the DD paclitaxel (DD AC→PG). Primary granulocyte colony-stimulating factor support was required; erythropoiesis-stimulating agents (ESAs) were used at the investigator's discretion. There were no significant differences in 5-year disease-free survival (DFS) between DD AC→PG and DD AC→P (80.6% v 82.2%; HR, 1.07; P = .41), between DD AC→PG and TAC (80.6% v 80.1%; HR, 0.93; P = .39), in 5-year overall survival (OS) between DD AC→PG and DD AC→P (90.8% v 89.1%; HR, 0.85; P = .13), between DD AC→PG and TAC (90.8% v 89.6%; HR, 0.86; P = .17), or between DD AC→P versus TAC for DFS (HR, 0.87; P = .07) and OS (HR, 1.01; P = .96). Grade 3 to 4 toxicities for TAC, DD AC→P, and DD AC→PG, respectively, were febrile neutropenia (9%, 3%, 3%; P < .001), sensory neuropathy (< 1%, 7%, 6%; P < .001), and diarrhea (7%, 2%, 2%; P < .001). Exploratory analyses for ESAs showed no association with DFS events (HR, 1.02; P = .95). Adding G to DD AC→P did not improve outcomes. No significant differences in efficacy were identified between DD AC→P and TAC, although toxicity profiles differed.

Adding trastuzumab to adjuvant chemotherapy provides significant clinical benefit in patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. A cost-effectiveness analysis was performed to assess clinical and economic implications of adding trastuzumab to adjuvant chemotherapy, based upon joint analysis of NSABP B-31 and NCCTG N9831 trials. A Markov model with 4 health states was used to estimate the cost utility for a 50-year-old woman on the basis of trial results through 4 years and estimates of long-term recurrence and death based on a meta-analysis of trials. From 6 years onward, rates of recurrence and death were assumed to be the same in both trastuzumab and chemotherapy-only arms. Incremental costs were estimated for diagnostic and treatment-related costs. Analyses were from payer and societal perspectives, and these analyses were projected to lifetime and 20-year horizons. Over a lifetime, the projected cost of trastuzumab per quality-adjusted life year (QALY; discount rate 3%) gained was 26,417 dollars (range 9,104 dollars-69,340 dollars under multiway sensitivity analysis). Discounted incremental lifetime cost was 44,923 dollars, and projected life expectancy was 3 years longer for patients who received trastuzumab (19.4 years vs 16.4 years). During a 20-year horizon, the projected cost of adding trastuzumab to chemotherapy was 34,201 dollars per QALY gained. Key cost-effectiveness drivers were discount rate, trastuzumab price, and probability of metastasis. The cost-effectiveness result was robust to sensitivity analysis. Trastuzumab for adjuvant treatment of early stage breast cancer was projected to be cost effective over a lifetime horizon, achieving a cost-effectiveness ratio below that of many widely accepted oncology treatments.

The efficacy of high-dose chemotherapy (HDC) and autologous hemopoietic progenitor cell transplantation (AHPCT) for breast cancer (BC) patients has been an area of intense controversy among the medical oncology community. The aim of this study was to assess toxicity and efficacy of this procedure in a large cohort of high-risk primary BC patients who underwent AHPCT in Italy. A total of 1183 patients receiving HDC for high-risk BC (HRBC) (>3 positive nodes) were identified in the Italian registry. The median age was 46 years, 62% of patients were premenopausal at treatment, 60.1% had endocrine-responsive tumors, and 20.7% had a human epidermal growth factor receptor 2 (HER2)-positive tumor. The median number of positive lymph nodes (LN) at surgery was 15, with 71.5% of patients having ≥ 10 positive nodes. Seventy-three percent received an alkylating agent-based HDC as a single procedure, whereas 27% received epirubicin or mitoxantrone-containing HDC, usually within a multitransplantation program. The source of stem cells was peripheral blood in the vast majority of patients. Transplantation-related mortality was .8%, whereas late cardiac and secondary tumor-related mortality were around 1%, overall. With a median follow-up of 79 months, median disease-free and overall survival (OS) in the entire population were 101 and 134 months, respectively. Subgroup analysis demonstrated that OS was significantly better in patients with endocrine-responsive tumors and in patients receiving multiple transplantation procedures. HER2 status did not affect survival probability. The size of the primary tumor and number of involved LN negatively affected OS. Adjuvant HDC with AHPCT has a low mortality rate and provides impressive long-term survival rates in patients with high-risk primary BC. Our results suggest that this treatment modality should be proposed in selected HRBC patients and further investigated in clinical trials. Copyright © 2014 American Society for Blood and

Whether the administration of luteinizing hormone-releasing hormone analogues (LHRHa) during chemotherapy is a reliable strategy to preserve ovarian function is controversial owing to both the lack of data on long-term ovarian function and pregnancies and the safety concerns about the potential negative interactions between endocrine therapy and chemotherapy. To evaluate long-term results of LHRHa-induced ovarian suppression during breast cancer chemotherapy. Parallel, randomized, open-label, phase 3 superiority trial conducted at 16 Italian sites. Between October 2003 and January 2008, 281 premenopausal women with stage I to III hormone receptor-positive or hormone receptor-negative breast cancer were enrolled. Last annual follow-up was June 3, 2014. Patients were randomized to receive adjuvant or neoadjuvant chemotherapy alone (control group) or chemotherapy plus triptorelin (LHRHa group). The primary planned end point was incidence of chemotherapy-induced early menopause. Post hoc end points were long-term ovarian function (evaluated by yearly assessment of menstrual activity and defined as resumed by the occurrence of at least 1 menstrual cycle), pregnancies, and disease-free survival (DFS). A total of 281 women (median age, 39 [range, 24-45] years) were randomized. Median follow-up was 7.3 years (interquartile range, 6.3-8.2 years). The 5-year cumulative incidence estimate of menstrual resumption was 72.6% (95% CI, 65.7%-80.3%) among the 148 patients in the LHRHa group and 64.0% (95% CI, 56.2%-72.8%) among the 133 patients in the control group (hazard ratio [HR], 1.28 [95% CI, 0.98-1.68]; P = .07; age-adjusted HR, 1.48 [95% CI, 1.12-1.95]; P = .006). Eight pregnancies (5-year cumulative incidence estimate of pregnancy, 2.1% [95% CI, 0.7%-6.3%]) occurred in the LHRHa group and 3 (5-year cumulative incidence estimate of pregnancy, 1.6% [95% CI, 0.4%-6.2%]) in the control group (HR, 2.56 [95% CI, 0.68-9.60]; P = .14; age-adjusted HR, 2.40 [95% CI, 0

Parametrial involvement (PMI) is one of the most important factors influencing prognosis in locally advanced stage cervical cancer (LACC) patients. We aimed to evaluate PMI rate among LACC patients undergoing neoadjuvant chemotherapy (NACT), thus evaluating the utility of parametrectomy in tailor adjuvant treatments. Retrospective evaluation of consecutive 275 patients affected by LACC (IB2-IIB), undergoing NACT followed by type C/class III radical hysterectomy. Basic descriptive statistics, univariate and multivariate analyses were applied in order to identify factors predicting PMI. Survival outcomes were assessed using Kaplan-Meier and Cox models. PMI was detected in 37 (13%) patients: it was associated with vaginal involvement, lymph node positivity and both in 10 (4%), 5 (2%) and 12 (4%) patients, respectively; while PMI alone was observed in only 10 (4%) patients. Among this latter group, adjuvant treatment was delivered in 3 (1%) patients on the basis of pure PMI; while the remaining patients had other characteristics driving adjuvant treatment. Considering factors predicting PMI we observed that only suboptimal pathological responses (OR: 1.11; 95% CI: 1.01, 1.22) and vaginal involvement (OR: 1.29 (95%) CI: 1.17, 1.44) were independently associated with PMI. PMI did not correlate with survival (HR: 2.0; 95% CI: 0.82, 4.89); while clinical response to NACT (HR: 3.35; 95% CI: 1.59, 7.04), vaginal involvement (HR: 2.38; 95% CI: 1.12, 5.02) and lymph nodes positivity (HR: 3.47; 95% CI: 1.62, 7.41), independently correlated with worse survival outcomes. Our data suggest that PMI had a limited role on the choice to administer adjuvant treatment, thus supporting the potential embrace of less radical surgery in LACC patients undergoing NACT. Further prospective studies are warranted. Copyright © 2015 Elsevier Ltd. All rights reserved.

The role of radiation therapy (RT) in resected pancreatic cancer (PC) remains incompletely defined. We sought to determine clinical variables which predict for local-regional recurrence (LRR) to help select patients for adjuvant RT. We identified 73 patients with PC who underwent resection and adjuvant gemcitabine-based chemotherapy alone. We performed detailed radiologic analysis of first patterns of failure. LRR was defined as recurrence of PC within standard postoperative radiation volumes. Univariate analyses (UVA) were conducted using the Kaplan-Meier method and multivariate analyses (MVA) utilized the Cox proportional hazard ratio model. Factors significant on UVA were used for MVA. At median follow-up of 20 months, rates of local-regional recurrence only (LRRO) were 24.7%, LRR as a component of any failure 68.5%, metastatic recurrence (MR) as a component of any failure 65.8%, and overall disease recurrence (OR) 90.5%. On UVA, elevated postoperative CA 19-9 (>90 U/mL), pathologic lymph node positive (pLN+) disease, and higher tumor grade were associated with increased LRR, MR, and OR. On MVA, elevated postoperative CA 19-9 and pLN+ were associated with increased MR and OR. In addition, positive resection margin was associated with increased LRRO on both UVA and MVA. About 25% of patients with PC treated without adjuvant RT develop LRRO as initial failure. The only independent predictor of LRRO was positive margin, while elevated postoperative CA 19-9 and pLN+ were associated with predicting MR and overall survival. These data may help determine which patients benefit from intensification of local therapy with radiation.

Background. The 21-gene Oncotype DX Recurrence Score assay is a validated assay to help decide the appropriate treatment for estrogen receptor-positive (ER+), early-stage breast cancer (EBC) in the adjuvant setting. The choice of adjuvant treatments might vary considerably in different countries according to various treatment guidelines. This prospective multicenter study is the first to assess the impact of the Oncotype DX assay in the French clinical setting. Methods. A total of 100 patients with ER+, human epidermal growth factor receptor 2-negative EBC, and node-negative (pN0) disease or micrometastases in up to 3 lymph nodes (pN1mi) were enrolled. Treatment recommendations, physicians’ confidence before and after knowing the Recurrence Score value, and physicians’ perception of the assay were recorded. Results. Of the 100 patients, 95 were evaluable (83 pN0, 12 pN1mi). Treatment recommendations changed in 37% of patients, predominantly from chemoendocrine to endocrine treatment alone. The proportion of patients recommended chemotherapy decreased from 52% pretest to 25% post-test. Of patients originally recommended chemotherapy, 61% were recommended endocrine treatment alone after receiving the Recurrence Score result. For both pN0 and pN1mi patients, post-test recommendations appeared to follow the Recurrence Score result for low and high values. Physicians’ confidence improved significantly. Conclusion. These are the first prospective data on the impact of the Oncotype DX assay on adjuvant treatment decisions in France. Using the assay was associated with a significant change in treatment decisions and an overall reduction in chemotherapy use. These data are consistent with those presented from European and non-European studies. Implications for Practice: This study shows that in estrogen receptor-positive, human epidermal growth factor receptor 2-negative early breast cancer (either node-negative or with micrometastases in up to 3 lymph nodes

PurposePrevious 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.Materials and Methods93 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), amore » coaxial technique with a 2.7-Fr coaxial catheter was used.ResultsThe 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).ConclusionsThe 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.« less

Purpose Adjuvant high-dose chemotherapy (HDC) with autologous hematopoietic stem-cell transplantation (AHST) for high-risk primary breast cancer has not been shown to prolong survival. Individual trials have had limited power to show overall benefit or benefits within subsets. Methods We assembled individual patient data from 15 randomized trials that compared HDC versus control therapy without stem-cell support. Prospectively defined primary end points were relapse-free survival (RFS) and overall survival (OS). We compared the effect of HDC versus control by using log-rank tests and proportional hazards regression, and we adjusted for clinically relevant covariates. Subset analyses were by age, number of positive lymph nodes, tumor size, histology, hormone receptor (HmR) status, and human epidermal growth factor receptor 2 (HER2) status. Results Of 6,210 total patients (n = 3,118, HDC; n = 3,092 control), the median age was 46 years; 69% were premenopausal, 29% were postmenopausal, and 2% were unknown menopausal status; 49.5% were HmR positive; 33.5% were HmR negative, and 17% were unknown HmR status. The median follow-up was 6 years. After analysis was adjusted for covariates, HDC was found to prolong relapse-free survival (RFS; hazard ratio [HR], 0.87; 95% CI, 0.81 to 0.93; P < .001) but not overall survival (OS; HR, 0.94; 95% CI, 0.87 to 1.02; P = .13). For OS, no covariates had statistically significant interactions with treatment effect, and no subsets evinced a significant effect of HDC. Younger patients had a significantly better RFS on HDC than did older patients. Conclusion Adjuvant HDC with AHST prolonged RFS in high-risk primary breast cancer compared with control, but this did not translate into a significant OS benefit. Whether HDC benefits patients in the context of targeted therapies is unknown. PMID:21768471

Although surgical resection is the only curative strategy for pancreatic cancer, the prognosis of patients with pancreatic cancer remains poor. Recently, neoadjuvant treatment has been frequently employed as a promising treatment. Here, the mid-term results of neoadjuvant chemoradiotherapy(NACRT)using S-1, which has been performed in our hospital since 2008, are reported. Seventy-nine patients with resectable or borderline resectable pancreatic ductal adenocarcinoma, who had been intended to undergo NACRT treatment using S-1, were enrolled. The NACRT comprised radiotherapy( 1.8 Gy×28 days)and full-dose twice-daily oral S-1 given on the same days as the radiotherapy. The results of the NACRT and pancreatectomy and the patients' prognoses were evaluated. Fifty-five patients(69.6%)underwent pancreatectomy, with no case of mortality. The curative resection rate was 94.5%. Postoperative adjuvant chemotherapy was administered in 46 patients(83.6%). The 3-year survival rates of all 79 patients and 55 pancreatectomy patients were 40.1% and 50.4%, respectively. NACRT using S-1 was found to be feasible, and good mid-term outcomes were obtained. However, analysis of the long-term outcomes and comparisons with other novel anti-cancer drugs are still required.

To evaluate the long-term results of exclusive chemotherapy for T1-T3N0M0 glottic squamous cell carcinoma complete clinical responders after induction chemotherapy. Between 1985 and 2000, 69 patients with glottic squamous cell carcinoma complete clinical responders after induction chemotherapy were managed with exclusive chemotherapy at our department. Chemotherapy associated platinum and fluorouracil. This retrospective analysis evaluated actuarial survival, treatment morbidity, oncologic events and laryngeal preservation. Various independent factors were tested for potential correlation with survival and local recurrence. The 5-year Kaplan-Meier actuarial survival, local control, lymph node control estimate were 83,6%, 64,8%, 98,6% respectively. Chemotherapy never resulted in death. The 10-year actuarial metachronous second primary tumors estimate was 32%. The overall laryngeal preservation rate was 98,6%. Altogether our data and the review of the literature suggest that in patients achieving a complete clinical response after and induction based chemotherapy regimen, the completion of an exclusive chemotherapy regimen appears to be a valid alternative to the conventional use of radiotherapy or chemo-radiation protocols.

Physicians and oncology nurses must continue to update their knowledge on treatment and treatment-related side effects, while searching for effective methods to prevent or manage side effects. The objective of our study was to describe the incidence and response to treatment of the hand-foot syndrome (HFS) and the compliance with treatment of patients with stage IIB, IIIA, IIIB, and IIIC colon cancer that were treated with capecitabine alone as adjuvant therapy. Between September 2005 and September 2006, 84 patients fulfilled the inclusion criteria and were included in this retrospective analysis of prospectively collected data. The treatment compliance rate was 90.5% (76 out of the 84 patients). The HFS developed in 65 patients (77.4%). Thirty-three patients (50.7%) had grade 1 HFS, 22 patients (33.8%) had grade 2 HFS and 10 patients (15.5%) had grade 3 HFS, as their most severe episode. For Grade 1 patients, the dose was maintained, and skin barrier cream and moist exposed burn ointment (MEBO) were applied. For Grade 2 patients, either the dose was maintained or 25% of the dose was reduced; MEBO and supportive care were provided. For Grade 3 patients, one cycle of chemotherapy was interrupted followed by dose adjustment; MEBO and supportive care were provided. HFS is manageable if both patients and oncology care teams are educated about HFS associated with capecitabine. The HFS is treated by patient education, preventive management, ointment application, conservative management, dose reduction, and interruption of chemotherapy administration.

This retrospective study analyzes the safety and feasibility of concurrent chemoradiotherapy (CRT) in adjuvant treatment of soft tissue sarcoma (STS). A total of 158 patients with STS were retrospectively analyzed. Anthracycline-based computed tomography was performed in high-risk patients. Acute radiotherapy toxicity and chemotherapy-related toxicity were assessed according to the Common Terminology Criteria for Adverse Events 4.0; late radiotherapy toxicity was recorded according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria. Fifty-four (34.2%) patients received CRT. Mean follow up was 5.4 years (range .2-21.1 years). Local DFS-recurrence-free survival, distant DFS-relapse-free survival, and overall survival were 79.1%, 76.4%, and 64.6%, respectively, at last follow-up. Leukopenia occurred in 11.4% of patients. Skin acute toxicity developed in 60.1% of patients and determined interruption of radiotherapy treatment in 19 (12%) patients. Nineteen patients (12%) experienced moderate fibrosis (grade 2). Mild and moderate joint stiffness was recorded in 16 (10.1%) patients. Size ≥5 cm was the only predictor of local recurrence at multivariate analysis (hazard ratio [HR] 9.65, 95% confidence interval [CI] 1.28-72.83, p = .028). Age and stage resulted as independent distant relapse predictors (HR 4.77, 95% CI 1.81-12.58, p = .002 and HR 4.83, CI 1.41-16.57, p = .012, respectively). At Cox regression univariate analysis, Karnofsky Performance Status, size, and stage were significant survival predictors (HR 2.23, 95% CI 1.02-4.87, p = .045; HR 2.88, 95% CI 1.10-7.52, p = .031; HR 2.59, 95% CI 1.11-6.04, p = .028). Concurrent CRT is a well-tolerated treatment option with no additional toxicity compared to exclusive radiotherapy or sequential CRT.

Breast cancer affects mostly older women but there are no guidelines especially devoted to adjuvant chemotherapy for this population. In this context, this study was carried out in a population-based cohort of French elderly women with breast cancer, to check adherence to the existing national guidelines according to the women's age, taking into account the evolution of the situation over time for women requiring chemotherapy. Between October 2006 and December 2008, all consecutive women included in the French Health registry for a biopsy-proven primary nonmetastatic breast cancer, aged 65-80 years at diagnosis, and living in South Eastern France, were asked to participate in a cohort study. Medical information was collected from physicians. The study population was restricted to the 223 women who were recommended adjuvant chemotherapy according to national guidelines. Those who received chemotherapy were compared to those who did not receive this treatment. Among these 223 women 55% had received chemotherapy. Only three women refused the treatment. Less than 8% have had a geriatric assessment before treatment decision and only two were proposed to participate in a clinical trial. After adjustment for comorbidity score, tumor characteristics, socio-demographic characteristics, and year of diagnosis, increasing patient age was independently associated with decreased guideline concordance for adjuvant chemotherapy. Women aged 75-80 years received chemotherapy more than four times less often than women aged 65-74 years. However, the percentage of women who received chemotherapy increased from 33% to 58% between 2006 and 2008, in parallel with the setting up of Onco-Geriatric Coordination Units in the area. In France, chronological age remains a barrier to receive chemotherapy for older breast cancer women but the establishment of a formal collaboration between oncologists and geriatricians seems to be an effective way to improve care delivery in this population. �

FOLFOX chemotherapy is widely used as an adjuvant treatment for advanced colon cancer. The duration of adjuvant chemotherapy is usually set to 6 months, which is based on a former study of 5-fluorouracil/leucovorin chemotherapy. However, the FOLFOX regimen is known to have complications, such as peripheral neuropathy. The aim of this study was to compare the survival rates and complications experienced by patients receiving either 4 or 6 months of FOLFOX chemotherapy. Retrospective data analysis was performed for stage II and III patients who underwent radical resection of colon cancer. We compared the 5-year survival rates and the occurrence of complications in patients who completed only 8 cycles of FOLFOX chemotherapy with patients who completed 12 cycles of chemotherapy. Among 188 patients who underwent adjuvant FOLFOX chemotherapy for stage II or III colon cancer, 83 (44.1%) completed 6 months of FOLFOX chemotherapy and 64 (34.0%) patients discontinued after 4 months of chemotherapy. The 5-year overall survival and disease-free survival rates did not show a significant difference. Patients in the 6-month group had peripheral neuropathy more frequently (p = 0.028). Five-year overall and disease-free survival were not significantly different between the 2 groups. Large-scale prospective studies are necessary for the analysis of complications and survival rates. © 2017 S. Karger AG, Basel.

Neoadjuvant or adjuvant therapy for resectable esophageal cancer: is there a standard of care?

Carcinoma of the esophagus is an aggressive and lethal disease with an increasing incidence worldwide. Despite changes in the treatment approach over the past two decades and even following complete resection, most patients will eventually relapse and die as a result of their disease. Several clinical trials evaluated different modalities in treating locally advanced esophageal cancer; however, because of stage migration and the changes in disease epidemiology, applying these trials to clinical practice has become a daunting task. We searched Medline and conference abstracts for randomized studies published in the past three decades. We restricted our search to articles published in English. Neoadjuvant chemoradiotherapy followed by surgical resection is an accepted standard of care in the United States for patients with locally advanced esophageal cancer. Esophagectomy remains an essential component of treatment and can lead to improved overall survival, especially when performed at high-volume institutions. The role of adjuvant chemotherapy following curative resection in patients who underwent neoadjuvant chemotherapy and radiation remains unclear. Several questions still need to be answered regarding the use of neoadjuvant or adjuvant therapy for patients with resectable esophageal cancer. The optimal chemotherapy regimen has not yet been identified for these patients, although newer therapies show promise.

Regional chemotherapy was first used for lung cancer 30 years ago. Since then, new methods of drug delivery and pharmaceuticals have been investigated in vitro, and in animals and humans. 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. PMID:22619512

Pharmacokinetics of metronomic chemotherapy: a neglected but crucial aspect.

Bocci, Guido; Kerbel, Robert S

2016-11-01

Metronomic chemotherapy describes the close, regular administration of chemotherapy drugs at less-toxic doses over prolonged periods of time. In 2015, the results of randomized phase III clinical trials demonstrated encouraging, albeit limited, efficacy benefits of metronomic chemotherapy regimens administered as adjuvant maintenance therapy for the treatment of breast cancer, or as maintenance therapy in combination with an antiangiogenic agent for metastatic colorectal cancer. Owing to the investigational nature of this approach, metronomic chemotherapy regimens are highly empirical in terms of the optimal dose and schedule for the drugs administered; therefore, greater knowledge of the pharmacokinetics of metronomic chemotherapy is critical to the future success of this treatment strategy. Unfortunately, such preclinical and clinical pharmacokinetic studies are rare. Herein, we present situations in which active drug concentrations have been achieved with metronomic schedules, and discuss their associated pharmacokinetic parameters. We summarize examples from the limited number of clinical studies in order to illustrate the importance of assessing such pharmacokinetic parameters, and discuss the influence this information can have on improving efficacy and reducing toxicity.

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

BACKGROUND The role of adjuvant chemoradiation therapy (CRT) in pancreatic cancer remains controversial. The primary aim of this study was to determine if CRT improved survival in patients with resected pancreatic cancer in a large, multiinstitutional cohort of patients. STUDY DESIGN Patients undergoing resection for pancreatic adenocarcinoma from seven academic medical institutions were included. Exclusion criteria included patients with T4 or M1 disease, R2 resection margin, preoperative therapy, chemotherapy alone, or if adjuvant therapy status was unknown. RESULTS There were 747 patients included in the initial evaluation. Primary analysis was performed between patients that had surgery alone (n = 374) and those receiving adjuvant CRT (n = 299). Median followup time was 12.2 months and 14.5 months for survivors. Median overall survival for patients receiving adjuvant CRT was significantly longer than for those undergoing operation alone (20.0 months versus 14.5 months, p = 0.001). On subset and multivariate analysis, adjuvant CRT demonstrated a significant survival advantage only among patients who had lymph node (LN)-positive disease (hazard ratio 0.477, 95% CI 0.357 to 0.638) and not for LN-negative patients (hazard ratio 0.810, 95% CI 0.556 to 1.181). Disease-free survival in patients with LN-negative disease who received adjuvant CRT was significantly worse than in patients who had surgery alone (14.5 months versus 18.6 months, p = 0.034). CONCLUSIONS This large multiinstitutional study emphasizes the importance of analyzing subsets of patients with pancreas adenocarcinoma who have LN metastasis. Benefit of adjuvant CRT is seen only in patients with LN-positive disease, regardless of resection margin status. CRT in patients with LN-negative disease may contribute to reduced disease-free survival. PMID:19476845

Recent breast cancer treatment guidelines recommend that higher-risk premenopausal patients should receive ovarian function suppression (OFS) as part of adjuvant endocrine therapy. If chemotherapy is also given, it is uncertain whether to select concurrent or sequential OFS initiation. We analyzed 1872 patients enrolled in the randomized phase III TEXT and SOFT trials who received adjuvant chemotherapy for hormone receptor-positive, HER2-negative breast cancer and upon randomization to an OFS-containing adjuvant endocrine therapy, initiated gonadotropin-releasing-hormone-agonist triptorelin. Breast cancer-free interval (BCFI) was compared between patients who received OFS concurrently with chemotherapy in TEXT (n = 1242) versus sequentially post-chemotherapy in SOFT (n = 630). Because timing of trial enrollment relative to adjuvant chemotherapy differed, we implemented landmark analysis re-defining BCFI beginning 1 year after final dose of chemotherapy (median, 15.5 and 8.1 months from enrollment to landmark in TEXT and SOFT, respectively). As a non-randomized treatment comparison, we implemented comparative-effectiveness propensity score methodology with weighted Cox modeling. Distributions of several clinico-pathologic characteristics differed between groups. Patients who were premenopausal post-chemotherapy in SOFT were younger on average. The median duration of adjuvant chemotherapy was 18 weeks in both groups. There were 231 (12%) BC events after post-landmark median follow-up of about 5 years. Concurrent use of triptorelin with chemotherapy was not associated with a significant difference in post-landmark BCFI compared with sequential triptorelin post-chemotherapy, either in the overall population (HR = 1.11, 95% CI 0.72-1.72; P = 0.72; 4-year BCFI 89% in both groups), or in the subgroup of 692 women <40 years at diagnosis (HR = 1.13, 95% CI 0.69-1.84) who are less likely to develop chemotherapy-induced amenorrhea.

Objectives to identify the prevalence, and describe the management of, neutropenia throughout the chemotherapy treatment among women with breast cancer. Methods observational study, cycles of chemotherapy. 116 neutropenic events were recorded, and 63.3% of the patients presented neutropenia at some point of their treatment, 46.5% of these presenting grade II. The management used was temporary suspension between the cycles and the mean number of delays was 6 days. The study was prospective and longitudinal, where the evaluation of the hematological toxicities was undertaken at each cycle of chemotherapy, whether neoadjuvant or adjuvant. Results 79 women were included, who received 572 cycles. However, the reasons for the suspensions were the lack of a space in the chemotherapy center, followed by neutropenia. Conclusion neutropenia is one of the most common and serious adverse events observed during the chemotherapy. Nursing must invest in research regarding this adverse event and in management strategies for organizing the public health system, so as to offer quality care. PMID:26107839

Despite the very good prognosis of endometrial cancer, a number of patients with localized disease relapse following surgery. Therefore, various adjuvant therapeutic approaches have been studied. The objective of this review is to evaluate the efficacy and safety of neoadjuvant and adjuvant therapies in patients with resectable endometrial cancer and to develop evidence-based recommendations. A review of the scientific literature published between January 1990 and June 2012 was performed. The search was limited to published phase III clinical trials and meta-analyses evaluating the efficacy of neoadjuvant or adjuvant therapies in patients with endometrial carcinoma or carcinosarcoma. A total of 23 studies and five meta-analyses were identified. The selected literature showed that in patients with a low risk of recurrence, post-surgical observation is safe and recommended in most cases. There are several therapeutic modalities available for treatment of endometrial cancers with higher risk of recurrence, including vaginal brachytherapy, external beam radiotherapy, chemotherapy, or a combination of these. Considering the evidence available to date, the CEPO recommends the following: (1)post-surgical observation for most patients with a low recurrence risk; (2)adjuvant vaginal brachytherapy for patients with an intermediate recurrence risk; (3)adjuvant pelvic radiotherapy with or without vaginal brachytherapy for patients with a high recurrence risk; addition of adjuvant chemotherapy may be considered as an option for selected patients (excellent functional status, no significant co-morbidities, poor prognostic factors); (4)adjuvant chemotherapy and pelvic radiotherapy with or without brachytherapy and para-aortic irradiation for patients with advanced disease; © 2013.

Objective To explore physically inactive breast and colon cancer patients’ prediagnosis exercise history and attitudes to physical activity (PA) and experiences in initiating PA while undergoing adjuvant chemotherapy. Design An explorative qualitative study guided the interpretive analysis of semistructured, open-ended interviews conducted at initiation of chemotherapy and after 12 weeks. The study was embedded in a pilot randomised controlled trial. Setting Participants were recruited from the Oncological Department at a hospital in Copenhagen, Denmark. Participants 33 patients with cancer, median age 49 years: 25 patients with breast cancer and 8 with colon cancer, 72% with a low cardiac respiratory fitness level and the majority with a high level of education. Patients received adjuvant chemotherapy, oncologist’s PA recommendation and exercise, cancer nurse specialist’s counselling prior to allocation to PA interventions or waitlist control group. Results Prediagnosis exercise had been excluded from patients’ daily lives due to perceptions of exercise as boring, lack of discipline and stressful work conditions for both genders. Recommendations from oncologists and nurses inspired the patients to reconsider their attitudes and behaviour by accepting recruitment and participation in PA interventions during chemotherapy. Despite extensive side effects, most patients adhered to their PA commitment due to their perception of the bodily, emotional and social benefits and support of healthcare professionals, peers and family. Conclusion The patients’ attitude towards exercise transformed from having no priority in patients’ daily lives prediagnosis to being highly prioritised. This study identified four important phases in the exercise transformation process during the patients’ treatment trajectory of relevance to clinicians in identifying, motivating and supporting physically inactive patients with cancer at long-term risk.

OBJECTIVE Primary osteosarcoma of the spine is a rare osseous neoplasm. While previously reported retrospective studies have demonstrated that overall patient survival is impacted mostly by en bloc resection and chemotherapy, the continued management of residual disease remains to be elucidated. This systematic review was designed to address the role of revision surgery and multimodal adjuvant therapy in cases in which en bloc excision is not initially achieved. METHODS A systematic literature search spanning the years 1966 to 2015 was performed on PubMed, Medline, EMBASE, and Web of Science to identify reports describing outcomes of patients who underwent biopsy alone, neurological decompression, or intralesional resection for osteosarcoma of the spine. Studies were reviewed qualitatively, and the clinical course of individual patients was aggregated for quantitative meta-analysis. RESULTS A total of 16 studies were identified for inclusion in the systematic review, of which 8 case reports were summarized qualitatively. These studies strongly support the role of chemotherapy for overall survival and moderately support adjuvant radiation therapy for local control. The meta-analysis revealed a statistically significant benefit in overall survival for performing revision tumor debulking (p = 0.01) and also for chemotherapy at relapse (p < 0.01). Adjuvant radiation therapy was associated with longer survival, although this did not reach statistical significance (p = 0.06). CONCLUSIONS While the initial therapeutic goal in the management of osteosarcoma of the spine is neoadjuvant chemotherapy followed by en bloc marginal resection, this objective is not always achievable given anatomical constraints and other limitations at the time of initial clinical presentation. This systematic review supports the continued aggressive use of revision surgery and multimodal adjuvant therapy when possible to improve outcomes in patients who initially undergo subtotal debulking of

To determine whether adjuvant chemotherapy (AC) after neoadjuvant chemoradiation and esophagectomy is associated with improved overall survival for patients with locally advanced esophageal cancer, and to evaluate how pathologic disease response to neoadjuvant treatment impacts this effect. Neoadjuvant chemoradiation is currently the preferred management approach for locoregional esophageal cancer. Although there is interest in the use of AC, the benefit of systemic therapy after neoadjuvant chemoradiation and esophagectomy is unclear. Retrospective cohort study of patients with esophageal cancer treated with neoadjuvant chemoradiation and esophagectomy in the National Cancer Data Base (2006-2012). Among 3592 patients with esophageal cancer (84.7% adenocarcinoma, 15.2% squamous cell carcinoma), 335 (9.3%) were treated with AC. AC was not associated with a significantly lower risk of death among patients with no residual disease (ypT0N0) or residual non-nodal disease (ypT+N0). Among patients with residual nodal disease (ypTanyN+), AC was associated with a 30% lower risk of death in the overall cohort [hazard ratio (HR) 0.70, (0.57-0.85)] and among those with adenocarcinoma [HR 0.69 (0.57-0.85)]. Using a 90-day postoperative landmark, findings were similar. Among patients with postoperative length of stay ≤10 days and no unplanned readmission, AC was associated with approximately 40% lower risk of death among patients with residual nodal disease [overall cohort, HR 0.63 (0.48-0.84); adenocarcinoma, HR 0.66 (0.49-0.88)]. AC after neoadjuvant chemoradiation and esophagectomy is associated with improved survival in patients with residual nodal disease. Our findings suggest AC may provide additional benefit for esophageal cancer patients, and merits further investigation.

Profound weight loss and malnutrition subsequent to severe dysphagia and cancer cachexia are cardinal symptoms in oesophageal cancer (OC). Low muscle mass/sarcopenia has been linked to toxicity during neo-adjuvant therapy in other cancers, with worser effects in sarcopenic obesity. In this study the association between sarcopenia and/or sarcopenic obesity and dose limiting toxicity (DLT) during cycle one chemotherapy in resectable OC patients was evaluated. Body composition was assessed from computed tomography scans of 72 consecutively diagnosed OC patients. Lean body mass and body fat mass were estimated. Patients were grouped as sarcopenic or non-sarcopenic based on pre-defined gender-specific cut-offs for sarcopenia, and as underweight/normal (BMI < 25) or overweight/obese (BMI ≥ 25). Sarcopenic obesity was defined as sarcopenia combined with overweight and obesity. DLT was defined as temporary reduction/delay or permanent discontinuation of drugs due to adverse effects. Odds ratios for developing toxicity were ascertained using multiple logistic regression. Of 72 patients, 85% (n = 61) were males. Sarcopenia and sarcopenic obesity were present in 31 (43%) and 10 (14%), respectively, prior to chemotherapy. Sarcopenic patients had significantly lower adipose tissue index (p = 0.02) compared to non-sarcopenic patients. Patients with DLT (n = 24) had lower skeletal muscle mass (p = 0.04) than those without DLT. Sarcopenic patients (OR = 2.47; 95% CI: 0.88-6.93) showed a trend towards increased DLT risk (p < 0.10). Logistic regression with BMI as an interaction term indicated higher DLT risk in sarcopenic patients with normal BMI (OR = 1.60; 95% CI 0.30-8.40), but was non-significant. In the sarcopenic obese, risk of DLT increased significantly (OR = 5.54; 95% CI 1.12-27.44). Sarcopenic and sarcopenic obese OC patients may be at a higher risk for developing DLT during chemotherapy compared to non-sarcopenic OC patients. Copyright © 2015

Nutraceuticals and chemotherapy induced peripheral neuropathy (CIPN): a systematic review.

Chemotherapy induced peripheral neuropathy [CIPN] is a common significant and debilitating side effect resulting from the administration of neurotoxic chemotherapeutic agents. These pharmaco-chemotherapeutics can include taxanes, vinca alkaloids and others. Moderate to severe CIPN significantly decreases the quality of life and physical abilities of cancer patients and current pharmacotherapy for CIPN e.g. Amifostine and antidepressants have had limited efficacy and may themselves induce adverse side effects. To determine the potential use of nutraceuticals i.e. vitamin E, acetyl-L-carnitine, glutamine, glutathione, vitamin B6, omega-3 fatty acids, magnesium, calcium, alpha lipoic acid and n-acetyl cysteine as adjuvants in cancer treatments a systematic literature review was conducted. Revised clinical studies comprised of randomized clinical trials that investigated the anti-CIPN effect of nutraceuticals as the adjuvant intervention in patients administered chemotherapy. Twenty-four studies were assessed on methodological quality and limitations identified. Studies were mixed in their recommendations for nutraceuticals. Currently no agent has shown solid beneficial evidence to be recommended for the treatment or prophylaxis of CIPN. The standard of care for CIPN includes dose reduction and/or discontinuation of chemotherapy treatment. The management of CIPN remains an important challenge and future studies are warranted before recommendations for the use of supplements can be made.

2018-07-01

Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy for which surgery is the mainstay of treatment and for which adjuvant radiation is infrequently employed; however, small, single-institution series suggest adjuvant radiation may improve outcomes. All patients with non-metastatic ACC treated with either surgery alone or surgery followed by adjuvant radiation were identified in the 2004-2013 National Cancer Database. Factors associated with receipt of radiation and the impact of adjuvant radiation on survival were determined by multivariable analysis. Of 1184 patients, 171 (14.4%) received adjuvant radiation. Patient demographics were similar between the two groups, but those receiving radiation were more likely to have had positive margins following surgery (37.4 vs. 14.6%; p < 0.001), evidence of vascular invasion (14.0 vs. 5.1%; p = 0.05), and receive concurrent chemotherapy (57.3 vs. 28.8%; p < 0.001). After adjustment for tumor and other treatment factors, only positive margins following surgery was associated with an increased likelihood of receiving adjuvant radiation (odds ratio 3.84, 95% confidence interval [CI] 1.95-7.56). Radiation therapy did not confer a difference in median overall survival in the general cohort. However, for patients with positive margins, adjuvant radiation was associated with a 40% decreased yearly risk of death after adjustment for concurrent chemotherapy (hazard ratio 0.60, 95% CI 0.40-0.92; p = 0.02). This survival advantage was not evident for other traditional high-risk features. Adjuvant radiation appears to decrease the risk of death in ACC patients with positive margins following surgical resection, but only a small percentage are currently receiving radiation. Multidisciplinary treatment with surgery and radiation should be considered for these patients.

The authors review their experience with 19 consecutive cases with either astrocytic tumour (glioblastoma multiforme one, anaplastic astrocytoma one, astrocytoma 4, pilocytic astrocytoma 4) or ependymoma (10 tumours in 9 patients) of the spinal cord who were treated during the period from 1982 to 1996. The patients included 10 male and 9 female patients with a median age of 38 years. The main tumour locations included the cervicomedullary region 5 the cervical cord (8), the thoracic cord (5) and one each in the thoracolumbar region and conus medullaris. While a total removal of the tumour was achieved in 8 out of 10 ependymomas, the initial treatment for astrocytic tumours was a partial resection in 5, and biopsy in the remaining 5. As adjuvant treatment, 8 patients received radiation therapy and 2 received chemotherapy. Two patients with an astrocytic tumour received chemotherapy only, while the remaining 9 received neither radiation therapy nor chemotherapy initially. After these treatments, 6 out of the 8 patients with low grade astrocytoma have remained alive for 1.3-12.6 years, while 2 patients with high grade astrocytic tumours died within 15 months following surgery. Eight out of 9 patients with an ependymoma have remained alive for 3.0-12.3 years, while one committed suicide 2 years after surgery. As a result, 14 patients are still alive; half of them are accompanied by a mild neurological dysfunction, while the remaining one has a moderate deficit. The postoperative results and the rationale for surgery is discussed, and an approach for utilising adjuvant therapy for high grade tumours is also suggested.

Background. The use of gemcitabine as an adjuvant modality for cholangiocarcinoma (CC) is increasing, but limited data are available on predictive biomarkers of response. Human equilibrative nucleoside transporter 1 (hENT-1) is the major transporter involved in gemcitabine intracellular uptake. This study investigated the putative predictive role of hENT-1 localization in tumor cells of CC patients undergoing treatment with adjuvant gemcitabine. Methods. Seventy-one consecutive patients with resected CC receiving adjuvant gemcitabine at our center were retrospectively analyzed by immunohistochemistry for hENT-1 localization in tumor cells. The main outcome measure was disease-free survival (DFS). Hazard ratios (HRs) of relapse and associated 95% confidence intervals (CIs) were obtained from proportional hazards regression models stratified on quintiles of propensity score. Results. Twenty-three (32.4%) cases were negative for hENT-1, 22 (31.0%) were positive in the cytoplasm only, and 26 (36.6%) showed concomitant cytoplasm/membrane staining. Patients with membrane hENT-1 had a longer DFS (HR 0.49, 95% CI 0.24–0.99, p = .046) than those who were negative or positive only in the cytoplasm of tumor cells. Notably, the association between DFS and membrane hENT-1 was dependent on the number of gemcitabine cycles (one to two cycles: HR 0.96, 95% CI 0.34–2.68; three to four cycles: HR 0.99, 95% CI 0.34–2.90; five to six cycles: HR 0.27, 95% CI 0.10–0.77). Conclusion. hENT-1 localization on tumor cell membrane may predict response to adjuvant gemcitabine in CC patients receiving more than four cycles of chemotherapy. Further prospective randomized trials on larger populations are required to confirm these preliminary results, so that optimal gemcitabine-based chemotherapy may be tailored for CC patients in the adjuvant setting. Implications for Practice: Gemcitabine is becoming an increasingly used adjuvant modality in cholangiocarcinoma (CC), but limited data are

In breast cancer management, the role of adjuvant radiation therapy (RT) has been the subject of intense controversy over the past several years, due to the improvement in neoadjuvant chemotherapy (NACT) prescription. One of the most controversial questions regarding indication for adjuvant RT is whether or not RT is essential in patients with early stage disease at diagnosis. The value of adjuvant RT remains highly debatable in those patients with clinically negative nodes at the completion of NACT. Areas covered: This review is focused on this gray area and is intended to assist with clinical decision-making. We provide a comprehensive review using PubMed and meeting proceedings of San Antonio Breast Cancer Symposium, European Society for Radiotherapy & Oncology, European Society of Medical Oncology and American Society of Clinical Oncology. Expert commentary: The identification of potential prognostic factors may lead to novel adjuvant RT indications. Phase III clinical trials are underway and their results will help guide treatment decisions.

We evaluated the effect of red ginseng on toxicity, health-related quality of life (HRQL) and survival after adjuvant chemotherapy in patients with epithelial ovarian cancer (EOC). A total of 30 patients with EOC were randomly assigned to placebo ( n = 15) and red ginseng groups ( n = 15). All patients took placebo or red ginseng (3000 mg/day) for three months. Then, we compared changes of genotoxicity, HRQL and survival between the two groups. As a result, red ginseng reduced micronuclei yield in comparison with placebo despite no difference of binucleated cells index. Although red ginseng increased serum levels of alanine aminotransferase and aspartate aminotransferase significantly, they were within the normal value. Moreover, there were no differences in adverse events between placebo and red ginseng groups. In terms of HRQL, red ginseng was associated with improved emotional functioning and decreased symptoms of fatigue, nausea and vomiting, and dyspnea, reduced anxiety and interference affecting life and improved daytime somnolence. However, there was no effect of red ginseng on prognosis of EOC. Conclusively, red ginseng may be safe and effective to reduce genotoxicity and improve HRQL despite no benefit of survival in patients with EOC who received chemotherapy.

Radical cystectomy with bilateral pelvic lymph node dissection is the standard of care for patients with clinically localized muscle-invasive bladder cancer. Survival after radical cystectomy is associated with final pathologic staging. Survival decreases with increasing pT stage because of the presence of occult micrometastases, indicating the need for systemic chemotherapy. Systemic chemotherapy is delivered as either neoadjuvant therapy preoperatively, or as adjuvant therapy postoperatively. This article reviews the evidence for neoadjuvant and adjuvant chemotherapy for the treatment of muscle-invasive bladder and upper tract urothelial cancer and offers recommendations based on these data and recently updated clinical guidelines.

Ampullary adenocarcinoma is a rare entity with limited data on prognostic factors. The aim of this study is to identify prognostic factors and assess the benefit of adjuvant therapy in patients with ampullary adenocarcinoma who underwent pancreatoduodenectomy. A cohort of 121 consecutive patients underwent pancreatoduodenectomy for ampullary adenocarcinoma from 2006 to 2016 at Mayo Clinic in Rochester, MN. All patients were confirmed by independent pathologic review to have ampullary carcinoma. Patient survival and its correlation with patient and tumor variables were evaluated by univariate and multivariate analysis. Fifty three patients (45%) received adjuvant therapy (34 patients had chemotherapy alone, while 19 patients received both chemotherapy and radiation therapy). Fifty seven percent of the patients were diagnosed with advanced stage disease (Stage IIB or higher). Nearly all patients (98.3%) had negative surgical margins. Median overall survival (OS) was 91.8 months (95% CI:52.6 months-not reached). In multivariate analysis, excellent performance status (ECOG: 0), adjuvant therapy, and advanced stage remained statistically significant. Adjuvant therapy was independently associated with improved disease free survival (Hazard ratio [HR]:0.52, P = 0.04) and overall survival (HR:0.45, P = 0.03) in patients with advanced disease. Adjuvant therapy was associated with improved survival in patients with resected ampullary cancer, especially with advanced stage disease. A multi-institutional randomized trial is needed to further assess the role of adjuvant therapy in ampullary adenocarcinoma.

QUASAR is a large trial of adjuvant chemotherapy for colorectal cancer in which clinicians could choose to deliver a standard adjuvant cytotoxic chemotherapy regimen, 5-fluorouracil (5-FU) and L-folinic acid (L-FA), in either a once-weekly or a four-weekly schedule. We report results of a non-randomised comparison between these schedules with respect to survival, recurrence and differential toxicity. In a factorial (2 x 2) trial design, QUASAR compared high-dose (175 mg) versus low-dose (25 mg) L-FA and levamisole versus placebo. The dose of 5-FU was fixed at 370 mg/m2 and although the recommended schedule was i.v. bolus delivery, daily for 5 days repeated four-weekly for 6 months, a significant proportion of randomising clinicians were constrained to deliver once-weekly 5-FU-L-FA for 30 weeks. Four thousand nine hundred twenty-seven patients were entered into QUASAR between May 1994 and October 1997, eighteen hundred twenty-nine of whom have recurred and sixteen hundred eighty-nine died. Similar numbers 2370 vs. 2559 were treated with the once-weekly and four-weekly schedules and the demographic features of the 2 groups were well balanced: stage C, 73.3% once-weekly vs. 71.0% four-weekly; colon, 68.0% vs. 68.3%; high-dose FA, 50.1% vs. 49.9%; levamisole, 49.3% vs. 49.3%; females, 40.2% vs. 41.7%; median age (years) 62 vs. 61. The risk of recurrence and survival were similar regardless of schedule: three-year survival was 70.6% once-weekly vs. 71.0% four-weekly; three-year recurrence risk was 35.6% once-weekly vs. 35.5% four-weekly; But, the once-weekly regimen was much less toxic: number of patients for whom toxicity was reported (once-weekly: four-weekly), stomatitis, 37 vs. 337; diarrhoea, 260 vs. 440; neutropenia, 20 vs. 153. The once-weekly regimen is much less toxic than and, apparently, about as effective as the four-weekly schedule. This suggests that the toxicity of 5-FU-L-FA adjuvant chemotherapy could be reduced substantially by weekly scheduling without

To explore physically inactive breast and colon cancer patients' prediagnosis exercise history and attitudes to physical activity (PA) and experiences in initiating PA while undergoing adjuvant chemotherapy. An explorative qualitative study guided the interpretive analysis of semistructured, open-ended interviews conducted at initiation of chemotherapy and after 12 weeks. The study was embedded in a pilot randomised controlled trial. Participants were recruited from the Oncological Department at a hospital in Copenhagen, Denmark. 33 patients with cancer, median age 49 years: 25 patients with breast cancer and 8 with colon cancer, 72% with a low cardiac respiratory fitness level and the majority with a high level of education. Patients received adjuvant chemotherapy, oncologist's PA recommendation and exercise, cancer nurse specialist's counselling prior to allocation to PA interventions or waitlist control group. Prediagnosis exercise had been excluded from patients' daily lives due to perceptions of exercise as boring, lack of discipline and stressful work conditions for both genders. Recommendations from oncologists and nurses inspired the patients to reconsider their attitudes and behaviour by accepting recruitment and participation in PA interventions during chemotherapy. Despite extensive side effects, most patients adhered to their PA commitment due to their perception of the bodily, emotional and social benefits and support of healthcare professionals, peers and family. The patients' attitude towards exercise transformed from having no priority in patients' daily lives prediagnosis to being highly prioritised. This study identified four important phases in the exercise transformation process during the patients' treatment trajectory of relevance to clinicians in identifying, motivating and supporting physically inactive patients with cancer at long-term risk. Clinicians should address young, highly educated patients with cancer at onset of adjuvant

This study examined the geographic variation and sociodemographic disparities in the use of oxaliplatin chemotherapy, which has not been widely studied in the past. Our results suggest that chemotherapy use varies across geographic regions. Patterns of use that relate specifically to oxaliplatin-containing chemotherapy can inform providers and researchers how newer regimens are being used as standard chemotherapy in a real-world setting. According to the National Cancer Comprehensive Network (NCCN), oxaliplatin with 5-fluorouracil and leucovorin (5-FU/LV) is the recommended adjuvant chemotherapy for patients with resected stage III colon cancer. Age and race are considered strong predictors of chemotherapy receipt, whereas geographic disparity has received minimal attention. The purpose of this study was to examine geographic variation and sociodemographic disparity in the use of chemotherapy in patients with stage III colon cancer, focusing specifically on oxaliplatin. A retrospective cohort of 4106 Medicare patients was identified from the Surveillance, Epidemiology and End Results (SEER)/Medicare linked database. Descriptive statistics show how oxaliplatin-containing chemotherapy was used in various geographic regions among different age and racial groups. Multiple logistic regression analysis was performed to examine the relationship between receipt of oxaliplatin-containing chemotherapy and geographic region while adjusting for other sociodemographic and tumor characteristics. Only 49% of the patients with stage III disease received adjuvant chemotherapy within 3 to 6 months of colon cancer-specific surgery. Patients aged 66 to 70 years were 78% more likely to receive chemotherapy than were those aged 80 years and older (P<.001). Patients in less urban regions were approximately 42% less likely to receive oxaliplatin chemotherapy than those residing in a big metro region (odds ratio [OR], 0.58; P=.008). Chemotherapy use varies across geographic regions

Introduction. For postmenopausal patients with hormone-sensitive breast cancer, outcome is worse with increasing age at diagnosis. The aim of this study was to assess the incidence of breast cancer recurrence (locoregional and distant), and contralateral breast cancer by age at diagnosis. Methods. Patients enrolled in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial were included. Primary endpoints were locoregional recurrence, distant recurrence, and contralateral breast cancer. Age at diagnosis was categorized as younger than 65 years, 65–74 years, and 75 years or older. Results. Overall, 9,766 patients were included, of which 5,349 were younger than 65 years (reference group), 3,060 were 65–74 years, and 1,357 were 75 years or older. With increasing age, a decreased administration of radiotherapy after breast conserving surgery (94%, 92%, and 88%, respectively) and adjuvant chemotherapy (51%, 23%, and 5%, respectively) was observed. Risk of distant recurrence increased with age at diagnosis; multivariable hazard ratio for patients aged 65–74 years was 1.20 (95% confidence interval [CI]: 1.00–1.44), hazard ratio for patients aged 75 years or older was 1.39 (95% CI: 1.08–1.79). Risks of locoregional recurrence and contralateral breast cancer were not significantly different across age groups. Conclusion. Elderly patients with breast cancer were at increased risk for distant recurrence. Other studies have shown that the risk of distant recurrence is mainly affected by adjuvant systemic therapy. All TEAM patients received adjuvant endocrine treatment; however, chemotherapy was administered less often in elderly patients. These findings are suggestive for consideration of chemotherapy in relatively fit elderly breast cancer patients with hormone-sensitive disease. PMID:23263290

Adjuvant endovesical treatment is a research field in constant exploration with the aim to minimize the risk of recurrence and progression of non muscle invasive bladder tumors. Over the last years, the administration of chemotherapy in a chemo hyperthermia regimen has been added to the existing regimens. There are various systems for its administration, but this article focus on HIVEC (Hyperthermic IntraVEsical Chemotherapy) and its current status. In this review article we update the results of this system in the case-scenarios it has been used (preoperative with ablative intention and as adjuvant therapy with prophylactic purposes), tolerance and security issues, on-going clinical trials and future perspectives.

The tolerance and safety associated with the administration order of the anthracycline and taxane drugs have not been evaluated. Breast cancer patients with node-positive or high-risk patients with node-negative were eligible. The feasibility and toxicity were evaluated in the following regimens--arm A, 3 courses of fluorouracil 500 mg/m(2), epirubicin 100 mg/m(2) and cyclophosphamide 500 mg/m(2) (FEC) followed by 3 courses of docetaxel 100 mg/m(2) (DOC); arm B, 3 courses of DOC followed by 3 courses of FEC. Forty-two patients were registered. The relative dose intensity was 94.2 % for FEC and 97.8 % for DOC in arm A, and 98.9 % for DOC and 95.2 % for FEC in arm B. In arm A, grade 3 or higher hematological toxicity was observed in nine patients, and febrile neutropenia developed in three patients with FEC. In arm B, grade 3 or higher hematological toxicity was observed in seven patients, but febrile neutropenia was not noted in any patient. The regimens in both arms A and B were safe regarding adjuvant chemotherapy for early breast cancer. However, DOC followed by FEC might be more tolerable. Further studies will maximize the results obtained with DOC followed by FEC.

Facilitating healthy levels of physical activity (PA) during chemotherapy is important for the psychosocial and physical health of breast cancer survivors. The primary objective of this feasibility study was to examine the effects of a broad-reach PA behavior change intervention among women with breast cancer receiving adjuvant chemotherapy. Breast cancer patients receiving adjuvant chemotherapy (N = 95) were randomly assigned to receive a PA resource kit consisting of tailored print materials and a step pedometer (intervention) or a standard public health PA recommendation (standard recommendation). The primary outcome was daily pedometer steps. Secondary outcomes were self-reported light, moderate, and vigorous intensity PA, total moderate-to-vigorous PA, and sedentary time. Assessments were conducted before and after adjuvant chemotherapy. Attrition was 19% (17 of 95). Intervention patients wore their step pedometer for 85 days (range, 35-144 days; SD = 26.4) for a 95% adherence rate. Analyses of covariance suggested that the intervention was not statistically superior to standard recommendation for daily average pedometer steps (-771; 95% CI = -2024 to 482; P = 0.22), total MVPA minutes (-4; 95% CI = -62 to 570; P = 0.90), or sedentary time (+160; 95% CI = -186 to 506; P = 0.42). This broach-reach and low intensive intervention was not more effective for promoting PA in breast cancer patients receiving chemotherapy than providing the standard public health guidelines for PA. Achieving physical activity behavior change during adjuvant breast cancer chemotherapy may require some level of supervised physical activity or more intensive (e.g., face-to-face, supervised) interventions. ©2015 American Association for Cancer Research.

Purpose: To analyze the prognostic factors predicting distant metastasis in patients undergoing adjuvant chemoradiation for extrahepatic bile duct (EHBD) cancer. Methods and Materials: Between January 1995 and August 2006, 166 patients with EHBD cancer underwent resection with curative intent, followed by adjuvant chemoradiation. There were 120 males and 46 females, and median age was 61 years (range, 34-86). Postoperative radiotherapy was delivered to tumor bed and regional lymph nodes (median dose, 40 Gy; range, 34-56 Gy). A total of 157 patients also received fluoropyrimidine chemotherapy as a radiosensitizer, and fluoropyrimidine-based maintenance chemotherapy was administered to 127 patients. Median follow-up durationmore » was 29 months. Results: The treatment failed for 97 patients, and the major pattern of failure was distant metastasis (76 patients, 78.4%). The 5-year distant metastasis-free survival rate was 49.4%. The most common site of distant failure was the liver (n = 36). On multivariate analysis, hilar tumor, tumor size {>=}2 cm, involved lymph node, and poorly differentiated tumor were associated with inferior distant metastasis-free survival (p = 0.0348, 0.0754, 0.0009, and 0.0078, respectively), whereas T stage was not (p = 0.8081). When patients were divided into four groups based on these risk factors, the 5-year distant metastasis-free survival rates for patients with 0, 1, 2, and 3 risk factors were 86.4%, 59.9%, 32.5%, and 0%, respectively (p < 0.0001). Conclusion: Despite maintenance chemotherapy, distant metastasis was the major pattern of failure in patients undergoing adjuvant chemoradiation for EHBD cancer after resection with curative intent. Intensified chemotherapy is warranted to improve the treatment outcome, especially in those with multiple risk factors.« less

Neo-adjuvant chemotherapy (NAC) followed by radical esophagectomy has been shown to prolong survival in patients with locally advanced esophageal squamous cell carcinoma (ESCC). However, neutropenia, one of the major adverse events due to NAC, influences the therapeutic course. The aim of this study is to clarify the relationship between neutropenia and therapeutic response in ESCC with NAC. A total of 117 patients with clinical stage II/III ESCC who had undergone NAC followed by radical esophagectomy were retrospectively analyzed in terms of the relationship between neutropenia and clinicopathological features or outcomes. Neutropenia was the major adverse event observed in 56 % (66/117) and grade 3/4 neutropenia occurred in 29 % of patients. Grade 3/4 neutropenia correlated with a high histological response (Grade 1b-3) (p < 0.01). Correlative analysis identified grade 3/4 neutropenia and poor differentiation as independent predictors of a high histological response (odds ratio 5.13 and 3.25, p < 0.01 and p = 0.01, respectively). Survival analysis showed that patients with a high histological response had significantly longer survival than those with a low histological response (Grade 0-1a) (p = 0.03), whereas no significant differences were found for survival according to the grade of neutropenia (p = 0.45). In a subgroup analysis according to histological response, grade 3/4 neutropenia correlated with worse survival in patients with a low histological response (p = 0.05). Severe neutropenia due to NAC correlates with a high histological response in ESCC. However, severe neutropenia may also result in a worse prognosis for patients with a low histological response.

Although cancer therapies have experienced great success nowadays, yet the associated toxic response and free radicals formation have resulted in significant number of treatment-induced deaths rather than disease-induced fatalities. Complications of chemotherapy have forced physicians to study antioxidant use as adjunctive treatment in cancer. This study aimed to evaluate the antioxidant role of vitamin E and N-acetyl cysteine (NAC) in overcoming treatment-induced toxicity in acute lymphoblastic leukaemia (ALL) during the intensive period of chemo-/radiotherapy, almost the first two months of treatment. Forty children newly diagnosed with ALL were enrolled in this study. Twenty children (group I) have taken vitamin E and NAC supplementations with chemotherapy and the other twenty children (group II) have not taken any adjuvant antioxidant therapy. They were evaluated clinically for the occurrence of complications and by the laboratory parameters (blood levels of glutathione peroxidase (Glu.PX) antioxidant enzyme, malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), liver enzymes, and bone marrow picture). Results revealed reduced chemotherapy and radiotherapy toxicity as evidenced by decreasing level of MDA, increasing level of Glu.Px and decreased occurrence of toxic hepatitis, haematological complications, and need for blood and platelet transfusions in group I compared to group II. We can conclude that vitamin E and NAC have been shown to be effective as antioxidant adjuvant therapy in children with ALL to reduce chemo-/radiotherapy-related toxicities during the initial period of treatment.

The use of gemcitabine as an adjuvant modality for cholangiocarcinoma (CC) is increasing, but limited data are available on predictive biomarkers of response. Human equilibrative nucleoside transporter 1 (hENT-1) is the major transporter involved in gemcitabine intracellular uptake. This study investigated the putative predictive role of hENT-1 localization in tumor cells of CC patients undergoing treatment with adjuvant gemcitabine. Seventy-one consecutive patients with resected CC receiving adjuvant gemcitabine at our center were retrospectively analyzed by immunohistochemistry for hENT-1 localization in tumor cells. The main outcome measure was disease-free survival (DFS). Hazard ratios (HRs) of relapse and associated 95% confidence intervals (CIs) were obtained from proportional hazards regression models stratified on quintiles of propensity score. Twenty-three (32.4%) cases were negative for hENT-1, 22 (31.0%) were positive in the cytoplasm only, and 26 (36.6%) showed concomitant cytoplasm/membrane staining. Patients with membrane hENT-1 had a longer DFS (HR 0.49, 95% CI 0.24-0.99, p = .046) than those who were negative or positive only in the cytoplasm of tumor cells. Notably, the association between DFS and membrane hENT-1 was dependent on the number of gemcitabine cycles (one to two cycles: HR 0.96, 95% CI 0.34-2.68; three to four cycles: HR 0.99, 95% CI 0.34-2.90; five to six cycles: HR 0.27, 95% CI 0.10-0.77). hENT-1 localization on tumor cell membrane may predict response to adjuvant gemcitabine in CC patients receiving more than four cycles of chemotherapy. Further prospective randomized trials on larger populations are required to confirm these preliminary results, so that optimal gemcitabine-based chemotherapy may be tailored for CC patients in the adjuvant setting. Gemcitabine is becoming an increasingly used adjuvant modality in cholangiocarcinoma (CC), but limited data are available on predictive biomarkers of response. In this study, patients

Clinical practice guidelines focusing on age-related adjuvant chemotherapy for rectal cancer are currently limited. The present study aimed to explore the impact of age on the efficacy of adjuvant oxaliplatin-based chemotherapy in patients with rectal cancer after neoadjuvant chemoradiotherapy. We performed a retrospective cohort analysis using data from the Surveillance, Epidemiology, and End Results-Medicare-linked database from 1992-2009. We enrolled patients with yp stages I-III rectal cancer who received neoadjuvant chemoradiotherapy and underwent curative resection. The age-related survival benefit of adding oxaliplatin to adjuvant 5-fluorouracil (5-FU) chemotherapy was evaluated using Kaplan-Meier survival analysis with propensity score-matching and Cox proportional hazards models. Comparing the oxaliplatin group with the 5-FU group, there were significant interactions between age and chemotherapy efficacy in terms of overall survival (OS) (p for interaction = 0.017) among patients with positive lymph nodes (ypN+). Adding oxaliplatin to 5-FU could prolong survival in patients aged < 73 years and ypN+ category, and but did not translate into survival benefits in patients aged ≥ 73 years and ypN+ category. No significant interactions were observed among ypN- patients, and oxaliplatin did not significantly improve OS, regardless of age. In patients with rectal cancer who have already received neoadjuvant chemoradiotherapy and undergone curative resection, adding oxaliplatin to 5-FU could prolong OS in patients aged < 73 years and ypN+ category. However, adding oxaliplatin did not translate into survival benefits in patients age ≥ 73 years and ypN+ category, or in ypN- patients.

Olfactory neuroblastoma (ONB) is a rare entity that constitutes less than 5% of nasosinusal malignancies. Mainstream treatment consists in surgical resection+/-adjuvant radiotherapy. By exposing results observed with apparition of new therapeutic options as neoadjuvant chemotherapy, the objective is to evaluate a series and a review of the current literature. A retrospective review was conducted including patients diagnosed and followed-up for ONB from 2008 to 2015 in our institution. 9 patients were included. Mean follow-up of 52.5 months (range 10-107). Kadish stage: A, 1 patient (11.1%) treated with endoscopic surgery; B, 2 patients (22.2%) treated with endoscopic surgery (one of them received adjuvant radiotherapy); C, 6 patients (66.7%), 4 patients presented intracranial extension and were treated with neoadjuvant chemotherapy followed by surgery and radiotherapy. The other 2 patients presented isolated orbital extension, treated with radical surgery (endoscopic or craniofacial resection) plus radiotherapy. The 5-year disease free and overall survival observed was 88.9%. Neoadjuvant chemotherapy could be an effective treatment for tumor reduction, improving surgical resection and reducing its complications.

The aim of this study was to compare the effectiveness of prophylactic single fixed dose of pegfilgrastim and daily administration of filgrastim on febrile neutropenia (FN), severe neutropenia, treatment delay, and dose reduction in patients with breast cancer receiving dose-dense adjuvant chemotherapy. A retrospective cohort study with 1058 breast cancer patients matched by age and chemotherapy was conducted. The primary endpoints were FN, severe (grade 3, 4) neutropenia, dose reduction (>10 % reduction of the dose planned), and treatment delay (dose given more than 2 days later). Eighteen episodes of FN (3.4%) in the filgrastim group and 23 (4.3%) in the pegfilgrastim group (p = 0.500) were recorded. More than half of the total episodes (27/41) occurred during the first 4 cycles of treatment. Patients who received filgrastim were almost three times more likely to experience a severe neutropenia episode and were significantly more likely to experience a dose reduction (18.5%) compared to those who received pegfilgrastim (10.8%) (p < 0.001). The percentage of patients, who received their planned dose on time, was significantly lower in patients receiving filgrastim (58%) compared to those receiving pegfilgrastim (72.4%, p < 0.001). No significant difference was detected on FN rate between daily administration of filgrastim and single administration of pegfilgrastim. However, patients receiving pegfilgrastim had a significantly lower rate of severe neutropenia, as well as dose reduction and treatment delay, thus, achieving a higher dose density.

Complaints of loss of memory and lack of concentration have been reported by long-term survivors of breast cancer. This mild cognitive impairment (MCI), also called "chemobrain" or "chemofog," has been the subject of a number of studies in the last few years. This cognitive impairment, although usually mild, must be studied to define possible risk factors for its development, and for future research into a preventive or therapeutic treatment approach. Long-term survivors of breast cancer must be followed to detect possible treatment sequelae as soon as possible. Since the number of these long-term survivors has increased in the last years, in part because of more active adjuvant treatments, our knowledge about the long-term side effects of these therapies has also grown.

Purpose This focused update addresses the use of MammaPrint (Agendia, Irvine, CA) to guide decisions on the use of adjuvant systemic therapy. Methods ASCO uses a signals approach to facilitate guideline updates. For this focused update, the publication of the phase III randomized MINDACT (Microarray in Node-Negative and 1 to 3 Positive Lymph Node Disease May Avoid Chemotherapy) study to evaluate the MammaPrint assay in 6,693 women with early-stage breast cancer provided a signal. An expert panel reviewed the results of the MINDACT study along with other published literature on the MammaPrint assay to assess for evidence of clinical utility. Recommendations If a patient has hormone receptor–positive, human epidermal growth factor receptor 2 (HER2)–negative, node-negative breast cancer, the MammaPrint assay may be used in those with high clinical risk to inform decisions on withholding adjuvant systemic chemotherapy due to its ability to identify a good-prognosis population with potentially limited chemotherapy benefit. Women in the low clinical risk category did not benefit from chemotherapy regardless of genomic MammaPrint risk group. Therefore, the MammaPrint assay does not have clinical utility in such patients. If a patient has hormone receptor–positive, HER2-negative, node-positive breast cancer, the MammaPrint assay may be used in patients with one to three positive nodes and a high clinical risk to inform decisions on withholding adjuvant systemic chemotherapy. However, such patients should be informed that a benefit from chemotherapy cannot be excluded, particularly in patients with greater than one involved lymph node. The clinician should not use the MammaPrint assay to guide decisions on adjuvant systemic therapy in patients with hormone receptor–positive, HER2-negative, node-positive breast cancer at low clinical risk, nor any patient with HER2-positive or triple-negative breast cancer, because of the lack of definitive data in these populations

To investigate the impact of pelvic radiation on survival in patients with uterine clear cell carcinoma (UCC) who received adjuvant chemotherapy. Patients with stage I-IV UCC who had undergone surgery and chemotherapy were identified from the Surveillance, Epidemiology, and End Results (SEER) programm 2000-2009. Patients were divided into those who received only chemotherapy and those who received both chemotherapy and radiation therapy. Kaplan-Meier curves and Cox regression models were used for analysis. Of the 317 patients included, 195 (62%) were in the chemotherapy only group and 122 (38%) were in the chemotherapy and radiation therapy group. Pelvic radiation was associated with significant improvement in overall survival (median 88 versus 25 months, 5 year survival: 58% versus 33%, P<0.001) in the chemotherapy and radiation therapy group compared with the chemotherapy only group for the entire cohort. On subset analysis, chemotherapy and radiation therapy was associated with improved overall survival in late stage disease (III-IV) (5 year 54% versus 22%, P<0.001) compared with the chemotherapy only group, whereas in stage I-II UCC, there was no difference in overall survival between the chemotherapy and radiotherapy group and the chemotherapy only group (5 year 65% versus 67%, P=0.69). In multivariable analysis, pelvic radiation was associated with improved survival in patients with late stage disease (hazard ratio 0.57, 95% confidence interval 0.35-0.94, P=0.03) but not for early stage disease (hazard ratio 0.81, 95% confidence interval 0.33-2.0, P=0.65). Other significant predictors were advanced stage, positive cytology and extensive lymphadenectomy. Radiation was associated with significant improvement in survival in advanced stage UCC, but not in early stage UCC. These data support the beneficial role of radiation therapy in UCC, especially in patients with advanced stage disease. Copyright © 2016 The Royal College of Radiologists. Published by Elsevier

Evaluate rates of chemotherapy and radiotherapy delivery in the treatment of uterine carcinosarcoma, and compare clinical outcomes of treated and untreated patients. The National Cancer Database was queried to identify patients diagnosed with uterine carcinosarcoma between 2003 and 2011. The impact of chemotherapy on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model. A total of 10,609 patients met study eligibility criteria. Stages I, II, III, and IV disease accounted for 2997 (28.2%), 642 (6.1%), 2037 (19.2%), and 1316 (12.4%) of the study population, respectively. Most patients (91.0%) underwent definitive surgery, and lymphadenectomy was performed in 68.7% of the patients. Chemotherapy was administered in 2378 (22.4%) patients, radiotherapy to 2196 (20.7%), adjuvant chemo-radiation to 1804 (17.0%), and 4231 (39.9%) of women did not received adjuvant therapy. Utilization of chemotherapy became more frequent over time. Over the entire study period, after adjusting for race, period of diagnosis, facility location, facility type, insurance provider, stage, age, treatment modality, lymph node dissection, socioeconomic status, and comorbidity index, there was an association between treatment modality and survival. The lowest hazard ratio observed was in patients that received chemo-radiation. The strongest quantitative predictor of death was stage at the time of diagnosis. In addition, surgical treatment, lymph node dissection, most recent time-periods, lower comorbidity index, and higher socioeconomic status were associated with improved survival. The overall rates of chemotherapy use have increased over time. Adjuvant chemotherapy and chemo-radiation were associated with improved survival. Copyright © 2015 Elsevier Inc. All rights reserved.

The objective of this study was to determine the frequency of recommendation of adjuvant chemotherapy by UK-based general veterinary practitioners (GVPs) for canine patients with high-grade mast cell tumours (HGMCTs), splenic haemangiosarcomas (SHSs) and appendicular osteosarcomas (AOSs); to determine which chemotherapeutic protocols are used by GVPs; and to evaluate reasons why chemotherapy may or may not be recommended postoperatively. An internet survey was created in 2013 using an online programme and was distributed to GVPs. Questions relating to the use of adjuvant chemotherapy for three tumours were selected. In total, 300 responses were generated. Surgery was seen as primary therapy by most GVPs for HGMCT (91 per cent) and SHS (88 per cent), but less frequently for AOS (59 per cent). Also, 90, 40 and 57 per cent of respondents recommended adjuvant chemotherapy for HGMCT, SHS and AOS, respectively. Of these, an appropriate chemotherapy protocol was not known by 25, 51 and 36 per cent of GVPs for HGMCT, SHS and AOS, respectively. From the GVPs not recommending chemotherapy, 29, 64 and 66 per cent did not believe chemotherapy to be efficacious for these tumours. The frequency of recommendation regarding postoperative chemotherapy is variable by tumour type. Reasons given why postoperative chemotherapy is not recommended also vary by tumour type.

To investigate the use and impact of granulocyte colony-stimulating factors (G-CSF) on chemotherapy delivery and neutropenia management in breast cancer in a clinical practice setting. IMPACT Solid was an international, prospective observational study in patients with a physician-assessed febrile neutropenia (FN) risk of ≥20%. This analysis focused on stages I-III breast cancer patients who received a standard chemotherapy regimen for which the FN risk was published. Chemotherapy delivery and neutropenia-related outcomes were reported according to the FN risk of the regimen and intent of G-CSF use. 690 patients received a standard chemotherapy regimen; 483 received the textbook dose/schedule with a majority of these regimens (84%) having a FN risk ≥10%. Patients receiving a regimen with a FN risk ≥10% were younger with better performance status than those receiving a regimen with a FN risk <10%. Patients who received higher-risk regimens were more likely to receive G-CSF primary prophylaxis (48% vs 22%), complete their planned chemotherapy (97% vs 88%) and achieve relative dose intensity ≥85% (93% vs 86%) than those receiving lower-risk regimens. Most first FN events (56%) occurred in cycles not supported with G-CSF primary prophylaxis. Physicians generally recommend standard adjuvant chemotherapy regimens and were more likely to follow G-CSF guidelines for younger, good performance status patients in the curative setting, and often modify standard regimens in more compromised patients. However, G-CSF support is not optimal, indicated by G-CSF primary prophylaxis use in <50% of high-risk patients and observation of FN without G-CSF support. Copyright © 2015 Elsevier Ltd.

Hidradenocarcinoma is a rare carcinoma of high malignant potential. It most metastasizes to regional lymph nodes and distant viscera. We report a case of 52-year-old woman who presented with an invasive hidradenocarcinoma of the finger, treated with surgical excision. The patient presented with skin and lymph node metastases four years after, treated by chemotherapy. Hidradenocarcinoma is an aggressive tumor. It seems important to use adjuvant therapies particularly for recurrent and metastatic forms.

Background Ovarian function suppression (OFS) significantly downregulates the concentration of plasma estrogens. However, it is unclear whether it offers any survival benefits if combined with adjuvant tamoxifen treatment in premenopausal women. This meta-analysis was designed to assess data from previous studies involving adjuvant tamoxifen treatment plus OFS in premenopausal breast cancer. Methods Electronic literature databases (PubMed, Embase, the Web of Science, and the Cochrane Library) were searched for relevant randomized controlled trials published prior to February 1, 2015. Only randomized controlled trials that compared tamoxifen alone with tamoxifen plus OFS for premenopausal women with breast cancer were selected. The evaluated endpoints were disease-free survival and overall survival. Results Four randomized controlled trials comprising 6,279 patients (OFS combination, n=3,133; tamoxifen alone, n=3,146) were included in the meta-analysis. There was no significant improvement in disease-free survival or overall survival with addition of OFS in either the whole population or the hormone receptor-positive subgroup. The risk of distant recurrence was not reduced with the addition of OFS in the whole population. A subgroup analysis showed that addition of OFS significantly improved overall survival in patients who were administered chemotherapy. Conclusion Based on the available studies, concurrent administration of OFS and adjuvant tamoxifen treatment for premenopausal women with breast cancer has no effect on prolonging disease-free survival and overall survival, excluding patients who were administered chemotherapy. It should not be widely recommended, except perhaps for women who were hormone-receptor positive and who were also administered adjuvant chemotherapy. PMID:26109867

Comparison of fluorouracil with additional levamisole, higher-dose folinic acid, or both, as adjuvant chemotherapy for colorectal cancer: a randomised trial. QUASAR Collaborative Group.

PubMed

2000-05-06

Standard adjuvant chemotherapy for colorectal cancer consists of fluorouracil with folinic acid or levamisole. The large QUASAR randomised trial aimed to investigate (in a two x two design) whether use of a higher dose of folinic acid or addition of levamisole to fluorouracil and folinic acid improved survival. Patients with colorectal cancer, without evident residual disease, were randomly assigned fluorouracil (370 mg/m2) with high-dose (175 mg) or low-dose (25 mg) L-folinic acid and either active or placebo levamisole. The fluorouracil and folinic acid could be given either as six 5-day courses with 4 weeks between the start of the courses or as 30 once-weekly doses. Levamisole (50 mg) or placebo was given three times daily for 3 days repeated every 2 weeks for 12 courses. The primary endpoint was mortality from any cause. Analyses were by intention to treat. Between 1994 and 1997, 4,927 patients were enrolled. 1,776 had recurrences and 1,576 died. Survival was similar with high-dose and low-dose folinic acid (70.1% vs 71.0% at 3 years; p=0-43), as were 3-year recurrence rates (36.0% vs 35.8%; p=0.94). Survival was worse with levamisole than with placebo (69.4% vs 71.5% at 3 years; p=0.06), and there were more recurrences with the active drug (37.0% vs 34.9% at 3 years; p=0.16). The inclusion of levamisole in chemotherapy regimens for colorectal cancer does not delay recurrence or improve survival. Higher-dose folinic acid produced no extra benefit in these regimens over that from low-dose folinic acid. Trials of chemotherapy versus no chemotherapy will show whether these four treatments are equally effective or equally ineffective.

Colorectal cancer (CRC) is one of the major health issues worldwide. 5-Fluorouracil (5-FU) is a cornerstone of chemotherapy for CRC and the major targets of 5-FU are folate-metabolizing enzymes. A total of 103 CRC patients with complete clinical data were included in this prospective cohort study. Genotyping was performed using polymerase chain reaction (PCR) followed by sequencing. Using Kaplan-Meier curves, log-rank tests, and Cox proportional hazard models, we evaluated associations between functional polymorphisms in four genes MTHFR (1298A>C and 677C>T), DPYD (496A>G and 85T>C), DHFR 19 bp del, and MTR (2756 A>G) with disease-free survival (DFS). The minor allele frequencies of MTHFR 1298A>C, MTHFR 677C>T, DPYD 496A>G, DPYD 85T>C, DHFR 19 bp del, and MTR 2756 A>G were 0.364, 0.214, 0.116, 0.209, 0.383, and 0.097, respectively. CRC patients carrying the homozygous GG genotype in DPYD 496A>G had 4.36 times shorter DFS than wild-type AA carriers, (DFS GG vs AA : 8.0 ± 4 vs 69.0 ± 10 months; HR 4.36, 95% CI 1.04-18; p = 0.04). Moreover, female carriers of homozygous CC genotype of DPYD 85T>C had shorter DFS compared to either heterozygous or wild-type genotypes, and were 12.7 times shorter than wild-type TT carriers (DFS CC vs TT : 5.0 ± 1.5 vs 42.0 ± 7.6 months; HR 12.7, 95% CI 2.2-71.4; p = 0.004). However, there were no significant associations with the other studied polymorphisms. Genetic polymorphism in DPYD seems to be associated with DFS in CRC patients receiving an adjuvant regimen of 5-FU/capecitabine-based chemotherapy. Further studies are needed to verify these findings.

The advantage of adjuvant chemotherapy (ACT) for treating Stage III colon cancer patients is well established and widely accepted. However, many patients with Stage III colon cancer do not receive ACT. Moreover, there are controversies around the effectiveness of ACT for Stage II patients. We investigated the administration of ACT and its association with overall survival in resected Stage II (overall and stratified by low-/high-risk) and Stage III colon cancer patients in three European countries including The Netherlands (2009-2014), Belgium (2009-2013) and Sweden (2009-2014). Hazard ratios (HR) for death were obtained by Cox regression models adjusted for potential confounders. A total of 60244 resected colon cancer patients with pathological Stages II and III were analyzed. A small proportion (range 9-24%) of Stage II and over half (range 55-68%) of Stage III patients received ACT. Administration of ACT in Stages II and III tumors decreased with higher age of patients. Administration of ACT was significantly associated with higher overall survival in high-risk Stage II patients (in The Netherlands (HR; 95%CI = 0.82 (0.67-0.99), Belgium (0.73; 0.59-0.90) and Sweden (0.58; 0.44-0.75)), and in Stage III patients (in The Netherlands (0.47; 0.43-0.50), Belgium (0.46; 0.41-0.50) and Sweden (0.48; 0.43-0.54)). In Stage III, results were consistent across subgroups including elderly patients. Our results show an association of ACT with higher survival among Stage III and high-risk Stage II colon cancer patients. Further investigations are needed on the selection criteria of Stages II and III colon cancer patients for ACT. © 2017 UICC.

We have utilized a two-stage study design to search for SNPs associated with the survival of breast cancer patients treated with adjuvant chemotherapy. Our initial GWS data set consisted of 805 Finnish breast cancer cases (360 treated with adjuvant chemotherapy). The top 39 SNPs from this stage were analyzed in three independent data sets: iCOGS (n=6720 chemotherapy-treated cases), SUCCESS-A (n=3596), and POSH (n=518). Two SNPs were successfully validated: rs6500843 (any chemotherapy; per-allele HR 1.16, 95% C.I. 1.08-1.26, p=0.0001, p(adjusted)=0.0091), and rs11155012 (anthracycline therapy; per-allele HR 1.21, 95% C.I. 1.08-1.35, p=0.0010, p(adjusted)=0.0270). The SNP rs6500843 was found to specifically interact with adjuvant chemotherapy, independently of standard prognostic markers (p(interaction)=0.0009), with the rs6500843-GG genotype corresponding to the highest hazard among chemotherapy-treated cases (HR 1.47, 95% C.I. 1.20-1.80). Upon trans-eQTL analysis of public microarray data, the rs6500843 locus was found to associate with the expression of a group of genes involved in cell cycle control, notably AURKA, the expression of which also exhibited differential prognostic value between chemotherapy-treated and untreated cases in our analysis of microarray data. Based on previously published information, we propose that the eQTL genes may be connected to the rs6500843 locus via a RBFOX1-FOXM1 -mediated regulatory pathway.
