Abstract
The cancer specific survival in 615 patients undergoing resection for carcinoma of the colon is presented. The patients were operated on and managed by 1 surgeon between 1950-1977. Computer analysis was made of the prospectively collected data. Results are presented as median survival in months and as percentage survivors at 5, 10, 15 and 20 yr. Curative resection gave a cancer specific survival of 75% at 66 mo., corresponding to 76% survival at 5 yr and 67% at 20 yr. Age and sex were not significant prognostic factors. Dukes'' Stages A, B and C had 5 yr survivals of 88, 78 and 68%, respectively, after curative resection. The median survival after palliative resection was 14 mo. Site of the primary tumor within the colon was of significant prognostic importance only when the poor survival in tumors of the transverse colon was compared with the favorable survival in those of the splenic flexure, ascending, descending and sigmoid colon.
