[Brachytherapy in carcinomas of anal canal and rectum: techniques and results]

Abstract

Conservative treatment of small anal canal and low rectal cancers is a valid alternative to radical surgery through combinated strategies including external beam and/or intracavitary irradiation, concomitant chemotherapy and 192 iridium implantation as a booster dose. Feasibility, tolerance and results are effective. Local control of the disease and the quality of the anal functions are good. The treatment requires great care in patient selection and follow-up.
