A Clinical Study of Colorectal Cancer Cases in Mie Prefecture

We reviewed 338 cases of colorectal cancer treated in our clinic since 1973. On these patients, 62% were aged 60 years or older. By location, the malignant tumor was found most frequenty in the rectum, followed by the sigmoid colon. Resection was perforoed in 94.3%, of the patients with curative resection accounted for 68.3%. In the curative resection group the cumulative 5-year and 10-year survival rates were 77% and 65, 9%, respectively. Early colorectal cancer was detected in only 26 patients. Mass screening for colorectal cancer using occult blood tests of feces had just recently started in our communities. Thus, further efforts to detect early colorectal cancer are needed.
