[Radiotherapy of carcinomas of the anal canal. Tenon Hospital experience]. / Traitement des cancers du canal anal par irradiation. Expérience de l'hôpital Tenon.

Since 1980, curative-intent radiation therapy of epidermoid carcinoma of the anal canal is the standard first line treatment. The combined concomitant chemotherapy and radiation therapy is presently established for locally advanced tumors more than 4 cm in length and/or with nodal involvement. We report the Tenon hospital experience since 1972 concerning the long term results after radiation therapy, the modifications of the radiation technique, and the evolution of treatment strategy.
