Radiation Therapy of Nasopharyngeal Carcinoma KCCH Experience (1964~1984) / 대한치료방사선과학회지

ABSTRACT

Total of 154 patients of pathologically proven and previously untreated nasopharyngeal carcinoma who were treated in the Department of Therapeutic Radiology, Korea Cancer Center Hospital during the period from 1964 to 1984 were analyzed. Minimal follow-up period of survivors was 3 years. Thirteen percent of the patients had T4 primary lesions and 65% had stage IV disease. Total radiation dose to the primary site was 1550~1750 ret in 82 and above 1750 ret in 72 patients. Local control was obtained in 79% of patients. Significant prognostic factors for the survival were tumor dose (above vs. below 1750 ret), age (below vs. above 30 years), stage (AJCC I-III vs IV), T stage (T1 vs. T2-4), and N stage (NO vs. N+).
