Chronological and clinicopathological changes of 196 colorectal cancer patients over 70 years of age (aged patients) were examined by comparing with those of 105 patients under 50 years of age (young patients) , to analyze the recent trends of colorectal cancer in Japan. The aged patients increased significantly in rate from 17.3% in the 1970's to 38.5% in the 1990's. Inversely, the young patients decreased from 25.2% in the 1970's to 6.6% in the 1990's. A significant difference between both patient-groups was found in only one, location of the cancer, out of 11 clinicopathological variables: rectal cancer in the aged patients was significantly more than in the young patients, while colon cancer in the former was significantly less than in the latter. From the results, rectal cancer may be concluded to increase recently in the aged and/or elderly people in Japan. Thus, periodical screening tests for rectal cancer may be necessary in these people, to prevent and detect the cancer as early as possible.
