Intracavitary irradiation of nasopharyngeal carcinoma using Ir-192 in Foley's catheter.

1. HDR Ir-192 intracavitary insertion in Foley's catheter for a boostered radiation dose to the nasopharynx is a very simple and safe technique and may increase the local control and survival of the patients. 2. Intracavitary brachytherapy should be done in all cases of NPC after the completion of external irradiation to increase local control that may lead to long term survival of the patients.
