[Prognostic anatomical features in the colon-rectum carcinoma (author's transl)].

We have reviewed 415 cases of colon-rectum carcinoma in order to establish the most important prognostic anatomical features. Furthermore, we have examined the associated adenomatous polyps, and the possible relationships between anatomical and histological aspects and Dukes stage of carcinoma. We have searched for some useful parameters to decide whether 5 centimeters between neoplasia and resection line is the correct surgical treatment.
