Abstract
80 patients with carcinoma of the nasopharynx classified according to TNM categories who have been treated in the RRTI between January 1947 and January 1966 are discussed. During 1947-1957 patients were treated by orthovoltage, and after this period by cobalt machine. The actuarial 5-year survival rate was 35%. Various factors such as age, sex, sign and symptoms, TNM classification, histology and type of treatment are discussed and related to the incidence of:local recurrence 27% (20/73); regional recurrence 29% (17/58); invasion of the base of the skull 21% (16/78); regional metastases 38% (30/78); distant metastases 49% (38/78), and to 5-year survival 33% (26/80). An overview is given of the present method of treatment in the RRTI based on the data in literature and obtained in this analysis.
