Abstract:
A total of 417 operated cases of colorectal cancer at Hiraka General Hospital during the 15-year period from 1974 to 1988 were analyzed and the following results were obtained.
1. There was a distinct tendency to increase in the numbers of resectable cases. By region, cases of cancers in sigmoid colon and upper third of rectum (S+Rs) and right side colon (C+A) were on the rise.
2. The ratio of patients aged over 70 years increased to reach 36 % recently. But the ratio of early stage cancer cases was 7.1 % on the average.
3. The over all resection rate was 90.6 %, and curative resection was performed in 78.5 % of colon cancer cases and 82.0 % of rectal cancer cases respectively.
4. The cumulative 10-year survival rate in curative resected cases was 74.7 % for colon cancer and 70.8 % for rectal cancer.
5. The rate of multiple cancer cases was as high as 13.4 %.
