Popis: Background: The aim of this study was to evaluate practicable predictors of 5-year disease-free survival (DFS) and impact of 5-fluorouracil (5-FU)-based adjuvant chemotherapy in stage IIa and IIb colon cancer. Materials and Methods: A total of 1474 patients with stage II colon cancer were enrolled in study. The independent predictors of 5-year DFS and the benefits of adjuvant chemotherapy were analyzed for patients with stage IIa (n = 771) and IIb (n = 703). Results: The incidences of pretreatment anemia, hypoalbuminemia, emergent surgery, and lymphovascular invasion (LVI) corresponded significantly to an advanced T-stage in patients with stage II colon cancer. Although the incidence of surgical morbidity was not different between stage IIa and IIb, stage II patients with hypoalbuminemia had a higher incidence of surgical morbidity than did those with normal serum albumin (17.2% vs. 9.6%, P < 0.001). The co-independent survival predictors in patients with stage IIa and IIb colon cancer were carcinoembryonic antigen (CEA < 5 ng/mL, P = 0.007 and 0.043), serum albumin (≥3.5 g/dL, P < 0.001 and P = 0.025), and nonsurgical morbidity (P < 0.001, both).
