並列摘要

Primary synchronous colon and rectum carcinoma is defined as that each single focus or lesion has to be histologically proven and there has to be histologically normal tissue between two such foci or lesions. Most of the previous published cases are chiefly composed of two single lesions; however, Marshak (1950) had discovered a case, which had five synchronous foci! The incidence of primary synchronous colon carcinomas is considered to be low, among all the patients suffering from colon carcinoma. In accordance with most foreign papers or issues, the incidences of synchronous colon carcinoma are between 1.8% to 9.1%
From Dec., 1976 to Sept, 1981, there are 799 proved cases of colorectal carcinomas in Chang Gung Memorial Hospital. Above all else, only 13 cases at last confirmed to be multiple primary synchronous colorectal carcinomas. Therefore, the incidence is then considered to be 1.62% in CGMH. This incidence rate is coincided with that of NTUH and foreign publishes. The age distribution of our collected cases is between 43 to 83 years old. Nine of them are male (69%); other four cases are female (31%). All the 13 patients were having two synchronous foci only. Other conditions of the patients are then analysed as below.
