BACKGROUND: Carcinoma arising in the cardioesophageal junction is a distinct clinical entity compared with tumors located in other regions of the stomach. This study was done to analyze the biologic characteristics of carcinoma of the gastric cardia compared with other gastric carcinomas. STUDY DESIGN: Clinicopathologic features and postoperative prognosis of 68 cases of carcinoma of the cardia were evaluated, in comparison with findings of tumors in other regions of the stomach. RESULTS: From 1975 to 1992, 68 (6.5 percent) of 1,042 patients with carcinoma of the stomach had adenocarcinoma of the cardia. Carcinoma of the cardia was characterized by a more advanced stage compared with carcinoma of other regions of the stomach. The incidence of early stage carcinoma (limited to the submucosal layer) was 11.8 percent in the cardia, 15.8 percent in die upper one-third, and 42.2 percent in the remaining middle and lower thirds of the stomach. When compared to carcinoma in other regions of the stomach, tumors of the cardia had a significantly poorer prognosis and there was a higher incidence of lymph node and hepatic metastasis. The five-year survival rates in patients with adenocarcinoma in the cardia, the upper one-third, and the remaining middle and lower thirds of the stomach were 35.3, 43.7, and 61.9 percent, respectively. Especially for patients with stage II and stage III disease, the prognosis was significantly worse with adenocarcinoma of the cardia than with carcinomas of the other regions of the stomach. CONCLUSIONS: Early detection is crucial to improve the survival of patients with carcinoma of the gastric cardia. Extended dissection of lymph nodes and aggressive postoperative chemotherapy in an attempt to prevent hepatic metastasis are highly recommended.
