Objective: We evaluated the prognostic value of the preoperative serum carcinoembryonic antigen (CEA) level in patients with colon cancer. Methods: We reviewed 474 patients who underwent potentially curative resection for nonmetastatic colon cancer. Patients were categorized into two groups according to the preoperative serum CEA level: low CEA (<5 ng/ml) and high CEA (>= 5 ng/ml) groups. Results: During the median 45-month follow-up period, the 5-year overall and disease-free survival rates for patients with a low CEA level were 81.7% and 82.4%, respectively, which were significantly higher than the rates for those with a high CEA level (69.9%; P = 0.011 and 70.6%; P = 0.002, respectively). A multivariate analysis revealed that a preoperative serum CEA level was a significant independent prognostic factor for both overall survival (P = 0.021) and disease-free survival (P = 0.026). Both the overall and disease-free survival rates in patients with stage II tumors differed significantly between the low and high CEA groups, whereas the rates did not different between those with stage I and III tumors. Conclusions: Preoperative serum CEA is a reliable predictor of recurrence and survival after curative surgery in patients with colon cancer, particularly in those classified as having stage II disease.
