The incidence of colorectal carcinoma has increased recently and one of the important problems in its treatment has been the detection of metachronous colorectal carcinoma and other associated neoplasms. In order to clarify the incidence of multiple (synchronous or metachronous) carcinoma and other associated neoplasms, 153 patients with colorectal carcinoma treated in our department during the period from January 1975 to December 1984 were analyzed. Of the 153 patients with colorectal carcinoma, there were 14 (9.0%) multiple carcinomas (11 synchronous and 3 metachronous carcinomas) and 7 (4.5%) other as sociated neoplasms. No histological differences were found between single carcinomas and multiple carcinomas. Of the 11 synchronous carcinomas, associated early carcinoma and advanced carcinoma were found in 6 (54, 5%). There was no familial link between single carcinoma and multiple carcinoma Polypoid lesions, especially adenoma, were highly prevalent in patients with multiple carcinoma. Other associated neoplasms were seen ; 1 in the prostate, 2 in the breast, 2 in the uterus and 2 in the stomach. These clinical observations indicated that careful postoperative observations should be carried out in patients with colorectal carcinoma for the early detection of metachronous carcinoma and other associated neoplasms.
