CLINICOPATHOLOGICAL STUDIES ON COLORECTAL CARCINOMAS OF PATIENTS IN OLD AGE

Abstract

Colorectal cacinomas of 58 patients aged 75 years or over who recieved bowel resections, were clinicopathologically studied compared with those of 373 patients aged 40 to 74 during 22 years from 1965 to 1986. Cancers in older patients indicated following features: (1) higher frequency in right sided colon, localized carcinoma and pm invased cancer, (2) variety in histological classification, (3) lower frequency in degree of matastasis and advanced stages, (4) satisfactory resectability (90.6%), operative mortality (5.3%), and 5-years survival (74.9%). These data suggest that radical surgery for colorectal carcinoma in aged patients is justificable.
