Abstract
PURPOSE To clarify the pathologic stages of adenocarcinoma of the gastric cardia in which the prognosis is worse than in adenocarcinoma of the middle or distal part of the stomach, and to determine prognostic factors in these stages by multivariate analysis. PATIENTS AND METHODS We analyzed 2,536 cases of surgically resected gastric adenocarcinoma of all pathologic stages. Four hundred seventy-two cases of gastric carcinoma, in which cumulative survival of gastric cardia was poor, were subjected to Cox regression analysis for prognostic factors, and to logistic regression analysis for factors influencing venous or lymphatic invasion. RESULTS The prognosis of adenocarcinoma of the gastric cardia was inferior when compared with similarly staged carcinomas of the middle or lower part of the stomach when there was invasion of proper muscle layer or subserosal layer, with no lymph node metastasis or with only adjacent (group 1) lymph nodes metastases (T2N0 or T2N1, according to the Japanese classification). In these stages, the prognostic factors were age, histologic type, venous invasion, and location of the tumor in the upper part of the stomach. Tumor location in the upper stomach was also a predictor for the presence of venous invasion. CONCLUSION The prognosis of adenocarcinoma of the gastric cardia is poor in patients with T2 tumors with no or few lymph node metastases. Additional treatment after surgery may be necessary to improve the survival of this population.
