title: [Multiple carcinoma in colon and rectum (author's transl)].
abstract: 43 multiple carcinomas of the colon and rectum were studied. 20 of those tumours showed a simultaneous manifestation, and 23 of them a metachroneous one. The interval between primary and secondary manifestation varied from 1 to 17 years. This clearly demonstrates that even after a very long tumour-free interval a secondary manifestation of the carcinoma can still be possible. The high percentage of multiple carcinomas of the colon calls for a careful preoperative diagnosis and an extensive intraoperative exploration of the whole colon. After hospitalisation a repeated check-up (3 months) is needed in the outpatients department to detect any secondary or recurrent carcinoma at the very earliest stage. In this way we were able to find 23 metachroneous manifestations and 27 recurrent carcinomas which were still resectable. The treatment of choice for polyposis coli is total colectomy.
