In Korea, the gastric cancer is the most frequent cancer in men and the cervical cancer is the most frequent in women.
The incidence of colo-rectal cancer in Korea is relatively lower than that of western countries, probably due to the difference in dietary habit. The diet of Korean has changed continuously to the western style. The purpose of this study is to evaluate the true incidence of cole-rectal cancer in Korea and to evaluate the possible correlation of dietary factors to the incidence of colon cancer. We analysed the Korean articles about the colerectal cancer from the Journal of Korean Colo-protoctological society the and Korean surgical society to evaluate the changes in operation methods and the survival rate of patients. The patient’s data from the Cancer Registry Programme in Republic of Korea from July 1983 to December 1995 were rerospectively evaluated and the correlation of the incidence of colorectal cancer was statistically analysed with dietary data from the Reports of National Nutritional Survey. We calculated a single (Pearson) correlation coefficient for colorectal cancer rates as compared to the dietary information. The results of study showed the incidence of colorectal cancer in Korea has yearly increased from 3.8 people per 100,000 population in 1982 to 10.0 people in 1993. The rate of colorectal cancer showed a positive correlation with the amount of dietary fat consumed, the fraction of acted people (>65 years old) and the Korean gross national product. The review of the articles from 1990 to 1995 showed that the incidence of rectal cancer and the survival rate of colorectal cancer were not changed significantly but the abdominoperineal resection for rectal cancer was progressively decreased, compared to operations before 1989. We also found (from the review of the articles) the different reporting methods for stages and survival rates. In conclusion, the incidence of colorectal cancer is progressively increasing and there is some relationship among increasing fat consumption, increasing aged people, increasing economic status and the increasing rate of colorectal cancer. The survival rate of colorectal cancer was not significantly improved, in spite of continous efforts of Korean surgeon’s efforts. We proposed several modalities for successful treatment of colorectal cancer the; early detection, the unification of s1aging methods, the multi-modality treatment and the dietary control of fat consumption.
