A total of 226 cases of advanced gastric cancer which occupied only one third of the stomach were analyzed in order to clarify whether and how lymphatic spread differed according to the tumor location and gross type of tumor. Out of the 226 patients, 45 cases had tumor in the upper third, 74 cases had it in the middle third, and 107 cases had it in the lower third of the stomach. The incidence of lymph node metastasis was found to be much higher for the tumors located in the lesser curvature (51.6%), greater curvature and posterior wall (54.4%), as compared to the tumors located in the anterior wall (28.0%). The tumors located in the upper third of the stomach did not show any metastasis in the N<SUP>3</SUP> node, while the tumors located in the lower third of the stomach did not show any metastasis in the left cardial nodes, short gastric nodes, and the nodes along the left gastroepiploic vessels. Similarly, the tumors from the middle third of the stomach did not invade the left cardial nodes.
