Department of Surgery, Omiya Medical Center, Jichi Medical School, Saitamashi, Saitama, Japan
Carcinoembryonic antigen (CEA) is an important tumor marker in the management of colorectal cancer. In general, serum CEA measurements are routinely used both pre- and postoperatively. An increase in the level of serum CEA in the postoperative follow-up strongly suggests recurrences. Preoperative CEA measurement is also important. A preoperative high CEA value suggests an advanced disease either locally or with a distant metastasis (1).
In curatively resected cases, the preoperative serum CEA level can be a useful predicting factor regarding the outcome of the
