BACKGROUND AND OBJECTIVES: Carcinoembryonic antigen (CEA) and carbohydrate antigen (CA19-9) are well known to be the most common tumor markers of colorectal carcinomas. However, the significance of increase in these markers to predict the prognosis of the patients remains a problem for debate. METHODS: One hundred three patients with colorectal carcinoma, who had been treated by resection and reconstruction of digestive tracts were studied. Correlation of preoperative serum value of CEA and CA19-9 with clinicopathologic features including prognosis of the patients was investigated. RESULTS: Preoperative elevation of both of the two markers proved to be an independent prognostic indicator, however, an elevation of only one of the two markers did not obtain a prognostic significance. CONCLUSIONS: Combined data of preoperative increase in CEA and CA19-9 in sera can provide a powerful and useful information to predict prognosis of patients with colorectal carcinoma.
