title: [Colon cancer with macroscopic invasion into surrounding organs].
abstract: Of 195 cases of colon cancer operated on between January 1972 and April 1985, 56 (30.3%) were with macroscopic invasion into surrounding organs. Among them, 45 patients underwent combined resection of the colon and one or more adjacent organs, and in 60% of them, the tumor invasion was verified microscopically. The organ invaded most frequently was the abdominal wall (26 cases), followed by the bladder (7) and stomach (6). The operative mortality was 8.9%, and the five-year survival rate in the curative resection group was 70.9%. Even the noncurative resection group showed a significantly longer mean survival time than the nonresectable group. Combined resection should be undertaken unless the patient is seriously ill.
