Carcinoembryonic Antigen (CEA) is a 180-200kD glycoprotein expressed at high level in the epithelial cells of the embryonic colon. The expression is stopped after birth. CEA serum content is low in normal population and only slightly elevated in heavy smokers. Increased serum CEA level was found associated with colorectal carcinoma, gastric carcinoma, pancreatic carcinoma, lung carcinoma, and breast carcinoma (3, 4, 5, 6). CEA has been used as a biomarker for carcinoma. However elevated CEA level not necessarily indicates neoplastic conditions, since high CEA expression has been observed in non-neoplastic conditions such as ulcerative colitis, pancreatitis and cirrhosis. Clinically, CEA level is mainly used to monitor the tumor recurrence after surgical resection of carcinoma (1, 2, 7).
