This study is the retrospective evaluation of ninety-six patients with biopsy-proven carcinoma of nasopharynx treated with radiotherapy at Yonsei University, College of Medicine, Radiation Oncology from January 1971 to December 1985. Patient's age ranged from 15 to 71 years with a median age of 49 years. Fifty-two point five percent of local control and $47.5\%$ of actuarial 5 year survival were achieved with radical radiotherapy. Five year survival rate for Stage I&II, III and IV were $75.0\%,\;74.6\%\;and\;41.4\%$, respectively. Distant metastasis rate was related with N stage $(N1\;12.5\%,\;N1\;0\%,\;N2\;23.5\%,\;N3\;32.1\%$and histologic type (lymphoepithelioma $41.7\%$, squamous cell carcinoma $6.5\%$) but not with T stage. Thirty-one of sixty-seven patient covered adequate radiation field received induction chemotherapy. However induction chemotherapy does not appear to improve over all survival.
