The present study examined whether survival after curative gastrectomy is related to the total number, frequency and rate of lymph node metastasis in 433 patients. Of these patients, 45.3% had lymph node metastasis. Of a total of 10, 130 dissected lymph nodes, 13.0% were positive for metastasis. The average number of positive nodes was 3.0. The rate, frequency and number of metastasized nodes increased as cancer progressed. In addition, the five-year survival rate correlated with nodal staging, depth of invasion, and the number and frequency of metastatic lymph nodes. The present findings suggest that the extent of lymph node disection is closely related to the number of metastatic node, and metastatic rate, and that extended lymph node dissection is efficacious in the treatment of gastric cancer.
