[Treatment of melanomas of the anorectal region].

The results of treatment of 42 cases of anorectal malignant melanoma were analysed. The disease accounted for 1.9% of rectal malignancies and 1.3% of melanomas at all other sites. Such procedures as sparing resection, abdomino-perineal extirpation of the rectum, radiation of chemotherapy were employed depending on the degree of tumor extension. Mean posttreatment survival was 32.4 +/- 4.3 months.
