教室における過去14年間の胃癌手術成績

Abstract

During the last 14 years, from April 1972 to March 1986, 808 cases were operated on for gastric cancer in our department. Operative procedures, clinicopathological findings and prognosis were investigated. The results were compared with those of other reports of treatment results of stomach carcinoma in Japan. Age, sex, localization, macroscopic classification, histologic type, histologic stage and resectability were almost the same as those reports. Pylorus-preserving nearly total gastrectomy was often performed in our department characteristically. The five-year suvival rate was 52% and the ten-year survival rate was 45% over-all. The five-year survival rate was 86% in stage Ⅰ, 61% in stage Ⅱ, 39% in stage Ⅲ and 5% in stage Ⅳ. The ten-year survival rate was 77% in stage Ⅰ, 49% in stage Ⅱ, 25% in stage Ⅲ and 4% in stage Ⅳ. The over-all five-year and ten-year survival rates in the first term (1972-1978) were 46% and 38%, respectively, and those in the latter term (1979-1985) were 58% and 51%, respectively. The survival rate in the latter term was significantly better than that in the first term.
