Prognostic value of carcinoembryonic antigen (CEA) in tumor tissue of patients with colorectal cancer

Anticancer Res. 2001 Jul-Aug;21(4B):3031-6.

Abstract

To establish the prognostic value of carcinoembryonic antigen (CEA) concentration in tumor tissue (T-CEA), normal colonic mucosa (N-CEA) and pre-operative serum (S-CEA), we studied 79 patients who underwent resections for colorectal cancer. The patients were separated into groups reflecting laboratory values lower or higher than a diagnostic value (S-CEA) or the median value of the entire population (T-CEA, N-CEA). A high S-CEA predicted for more advanced stage (p = 0.028), whereas no association was noted between stage and CEA concentration for T-CEA and N-CEA groups. The high S-CEA and T-CEA groups had a worse clinical outcome (p=0.0036 and p=0.024, respectively), while survival of high versus low N-CEA groups did not differ. By Cox's regression analysis, high T-CEA concentration was an independent variable for poor outcome (Hazard ratio, 3.15), while S-CEA and N-CEA were not. In conclusion, a high T-CEA concentration was the only independent predictor of poor outcome after resection for colorectal cancer.
