• To identify risk factors for recurrence in patients with stage II colon cancer, Cox proportional hazards regression analysis was performed in 194 patients with stage II colon cancer who underwent curative surgery between April 1997 and December 2008. Thirteen clinical and pathologic factors, including use of fluoropyrimidine-based adjuvant chemotherapy in 113 of the patients (58.2%), were assessed. By multivariate analysis, only obstruction, perforation, and T4-level invasion were identified as independent risk factors affecting disease-free survival (DFS) (P < 0.01). The 5-year DFS rate was 70.6% in patients with one or more risk factors (n = 68) and 96.0% in patients with no risk factors (n = 126) (P < 0.01). These results suggest that obstruction, perforation, and T4-level invasion are suitable candidates for prediction of tumor recurrence in patients with stage II colon cancer. The oxaliplatin-based adjuvant chemotherapy, which has been reported to be effective in stage III colon cancer patients, may improve the prognosis in high-risk stage II colon cancer patients.
