[The Rapeutic principles in malignant rectal polyps based on late results].

The late results of various treatment of 114 patients with malignant rectal polyps were found to be similar over a 5-25-year follow-up. On this basis, the following principles of therapy were established: 1. All rectal polyps should be removed completely. 2. Local removal of a malignant polyp, looking macroscopically benign and of favorable size and location, is justified, even though a cancer - not infiltrating the stalk - is situated in the head of the polyp. In any other case a radical operation is indicated. 3. Patients should be held under a life-long supervision. 4. The control should be performed as an organized care.
