In 35 patients with recurrent gastric cancer who had undergone curative gastrectomy, serum carcinoembryonic antigen (CEA) and CA 19-9 (carbohydrate antigen) rumor marker levels were investigated. At least one tumor marker was elevated in 24 (68.6%) patients. The levels of serum CA 19-9 and CEA markers were increased in 20 (57.1%,) and 12(34.3%) patients, respectively. This difference was not statistically significant. However, it may be important in terms of clinical practice.
