Abstract
For the non-metastatic nasopharyngeal carcinoma, external beam radiation therapy (median dose 64 Gy) and a boost of intracavitary irradiation (ICRT) has been given. Caesium-137 pellets of 40 mCi were used at a dose rate of 3-3.5 Gy/h, 1 cm from the sources. The median dose was 8.5 Gy. Overall 5-year actuarial survival for the 48 studied patients was 60.4% and LRFS was 64%. The procedure was well tolerated by our patients.
