The clinical outcomes and pathological data of 22 patients with nasopharyngeal carcinoma treated between 1985 and 1992 were reviewed. Patients consisted of 19 male and 3 female, ranging 23 to 77 years with a median age of 53 years.20 out of 22 patients(91%) were found as advanced stage(stage III and IV) according to stage classification(UICC). Pathological data by classification of nasopharyngeal(UICC) showed 2 keratinizing squamous cell carcinomas,9 non-keratinizing carcinomas,11 undifferentiated carcinomas.10 out of 22patients(45%) demonstrated recurrence, which were 2 local recurrence and 7 cervical lymphnode/distant metastases. The overall 3-year and 5-year survival rates determined by Kaplan-Meyer analysis were 46% and 11%, respectively. No significant improvement to survival rate by the combined chemotherapy with radiation therapy was observed in comparsion with radiation therapy alone.
