PURPOSE To develop recommendations for duration of adjuvant chemotherapy with a fluoropyrimidine and oxaliplatin for patients with completely resected stage III colon cancer based on the results of trials of 3 months compared with 6 months of treatment. METHODS ASCO convened an Expert Panel and conducted a systematic review of relevant studies. The guideline recommendations were based on the review of evidence by the Expert Panel. RESULTS Pooled data from the six International Duration Evaluation of Adjuvant Chemotherapy (IDEA) Collaboration randomized controlled trials comprise the evidence base for these guideline recommendations. RECOMMENDATIONS The recommendations for therapy duration apply to patients with completely resected stage III colon cancer who are being offered adjuvant chemotherapy with oxaliplatin and a fluoropyrimidine. Recommendations are informed by the findings of a recent pooled analysis of clinical trials that compared 6 months versus 3 months of oxaliplatin-based chemotherapy. For patients at a high risk of recurrence (T4 and/or N2), adjuvant chemotherapy should be offered for a duration of 6 months. For patients at a low risk of recurrence (T1, T2, or T3 and N1), either 6 months of adjuvant chemotherapy or a shorter duration of 3 months may be offered on the basis of a potential reduction in adverse events and no significant difference in disease-free survival with the 3-month regimen. In determining duration of therapy, the Expert Panel recommends a shared decision-making approach, taking into account patient characteristics, values and preferences, and other factors and including a discussion of the potential for benefit and risks of harm associated with treatment duration.

Albumin To Globulin Ratio

647 Background: Albumin to globulin ratio (AGR) has been reported to predict long term mortality in patients with several cancers. However, prognostic impact of preoperative AGR in colon cancer patients with curative intent has not yet been fully addressed. Therefore, we, for the first time, investigated the association between AGR and clinico-pathological findings including overall survival (OS) and disease free survival (DFS) in stage I-III colon cancer patients. Methods: Clinicopathological findings including preoperative laboratory data (carcinoembryonic antigen [CEA] and AGR) from 251 curative colon cancer patients were assessed as indicators of early recurrence and poor prognosis in this retrospective study. AGR was calculated as [AGR = albumin/ (total protein - albumin)]. The cut-off value of AGR was 1.32 in current study. Results: Several clinicopathological categories related with tumor progression such as lymph node metastasis, T4 tumor, large tumor size, undifferentiated tumor, venous and lymphatic invasion, and high CEA were significantly associated with low AGR level. The patients with low AGR were significantly poorer OS (P = 0.001) and DFS (P = 0.003) than those with high AGR, respectively. In addition, multivariate analyses demonstrated that low AGR was independently associated with early recurrence (HR = 2.87, P = 0.007) and poor prognosis (HR = 2.56, P = 0.008), respectively. On the other hand, sub analysis of survival curves revealed that stage III colon cancer patients with low AGR were significantly poorer OS (P = 0.007) and DFS (P = 0.02) than those with high AGR, respectively. Furthermore, significantly poorer OS and DFS were also shown in stage I-II colon cancer patients with low AGR, respectively (OS: P = 0.02, DFS: P = 0.01). Conclusions: Preoperative AGR was an independent predictor of early recurrence and poor prognosis in curative colon cancer patients. AGR may represent a simple, potentially useful predictive biomarker for selecting stage I-II colon cancer patients who might need adjuvant chemotherapy. Furthermore, AGR may select candidates who are better to introduce more intensive adjuvant chemotherapy after curative operation in stage III colon cancer patients.

Abstract Background: Adjuvant chemotherapy is relatively underused in older patients with colon cancer in Japan, and its age-specific effects on clinical outcomes remain unclear. This study aimed to assess the effect of adjuvant chemotherapy on survival benefit in stage III colon cancer patients stratified by age in a Japanese real-world setting. Methods: In this multi-center retrospective cohort study, we analyzed patient-level information through a record linkage of population-based cancer registry data and administrative claims data. The study population comprised patients aged ≥18 years who received a pathological diagnosis of stage III colon cancer and underwent curative resection between 2010 and 2014 at 36 cancer care hospitals in Osaka Prefecture, Japan. Patients were divided into two groups based on age at diagnosis (<75 and ≥75 years). The effect of adjuvant chemotherapy was analyzed using Cox proportional hazards regression models for all-cause mortality with inverse probability weighting of propensity scores. Adjusted hazard ratios were estimated for both age groups. Results: A total of 783 patients were analyzed; 476 (60.8%) were aged <75 years and 307 (39.2%) were aged ≥75 years. The proportion of older patients who received adjuvant chemotherapy (36.8%) was substantially lower than that of younger patients (73.3%). In addition, the effect of adjuvant chemotherapy was different between the age groups: the adjusted hazard ratio was 0.56 (95% confidence interval: 0.33-0.94, P=0.027) in younger patients and 1.07 (0.66-1.74, P=0.78) in older patients. Conclusions: The clinical effectiveness of adjuvant chemotherapy in older patients with stage III colon cancer appears limited under current utilization practices.

PURPOSE: Adjuvant postoperative treatment with fluorouracil (5-FU) and levamisole in curatively resected stage III colon cancer significantly reduces the risk of cancer recurrence and improves survival. Biochemical modulation of 5-FU with leucovorin has resulted in increased remission rates in metastatic colorectal cancer, thus reflecting an increased tumor-cell kill. The impact of 5-FU plus leucovorin on survival and tumor recurrence was analyzed in comparison with the effects of 5-FU plus levamisole in the prospective multicentric trial adjCCA-01. PATIENTS AND METHODS: Patients with a curatively resected International Union Against Cancer stage III colon cancer were stratified according to T, N, and G category and randomly assigned to receive one of the two adjuvant treatment schemes: 5-FU 400 mg/m2 body-surface area intravenously in the first chemotherapy course, then 450 mg/m2 × 5 days; 12 cycles, plus leucovorin 100 mg/m2 (arm A), or 5-FU plus levamisole (Moertel scheme; arm B). RESULTS: Six hundred eighty (96.9%) of 702 patients enrolled onto this study were eligible. After a median follow-up time of 46.5 months, the 5-FU plus leucovorin combination significantly improved disease-free survival (P = .037) and significantly decreased overall mortality (P = .0089) in comparison with 5-FU plus levamisole. In a multivariate proportional hazards model, adjuvant chemotherapy emerged as a significant prognostic factor for survival (P = .0059) and disease-free survival (P = .03). Adjuvant treatment with 5-FU plus levamisole as well as with 5-FU plus leucovorin was generally well tolerated; only a minority of patients experienced grade 3 and 4 toxicities. CONCLUSION: After a curative resection of a stage III colon cancer, adjuvant treatment with 5-FU plus leucovorin is generally well tolerated and significantly more effective than 5-FU plus levamisole in reducing tumor relapse and improving survival.
