THE MALIGNANT PATHOLOGICAL COLON-RECTUM P OLYP (REPRINTED FROM AKTUELLE CHIRURGIE, VOL 29, PG 139-143, 1994)

In 23 patients with malignant colorectal polyps we reviewed the freque ncy of recurrence. In the group without subsequent focal resection, 8 of 11 patients were without recurrent tumour after 2.7 (0.8-4.1) years , in the group with subsequent local or conventional colon resection, 10 of 12 patients after 5.3 (0.8-9.0) years. None of the patients show ed any evidence of residual tumour or lymph node metastasis. All recur rent tumours (2 X carcinoma, 3 X benign polyps) could be resected cura tively. There was no difference in recur rence in both groups. For saf e histopathological examination of malignant colorectal polypi in resp ect of depth of invasion, free resection margins and lymphatic vessel invasion, intraoperative fixation and marking must be performed since local recurrence was seen after more than 5 years, long-term follow up is necessary.
