Background: It is standard to use results of randomized controlled trials (RCT’s) for therapeutic decisions in community oncology. However participant selection in trial environments may not reflect real-world scenario. We aim to perform a retrospective analysis of patient profile and treatment outcomes in a community cancer center. Methods: Patients with stage III colon cancer offered adjuvant chemotherapy after curative resection from 2003-2010 (N=177) were reviewed. Eighty-seven patients with complete medical records were analyzed. Patient eligibility was assessed on criteria from the MOSAIC and NSABP C-07 trials. Eligible and ineligible patients were compared using Fisher’s exact test, Student’s t-test and Kaplan-Meier survival analysis. Results: The study group (females: 53%) with mean age of 65 years, was predominantly African American (60%). ECOG performance status was ≥ 2 in 13% patients. Only 29% satisfied all standard eligibility criteria. Ineligibility characteristics included age > 75 years (21%), non-malignant severe systemic disease (10%) and > 42 days from surgery to chemotherapy (39%). Seventy-five patients (86%) received chemotherapy. Chemotherapy regimens included FOLFOX (51%), FLOX (10%), FL (29%) and Capecitabine (8%). Total planned dose had to be modified in 64% patients with mean doses of 89% 5-fluorouracil and 79% oxaliplatin employed. The 3-year disease free survival (DFS) was 53% and 5-year overall survival (OS) was 56%. Age ≥ 69 years was significantly associated with poor 3-year DFS (P=0.013). On Kaplan-Meier survival analysis, the ineligible patient group had significantly reduced overall survival (hazard ratio, 2.88; 95% CI, 1.05-4.82; P= 0.037). Conclusions: This pilot venture studied adjuvant management of Stage III colon cancer in a real-world setting. Our results reveal that over 70% patients did not meet standard eligibility criteria and show decreased 5-year OS among these patients that needs to be addressed in future prospective RCT’s.
