[Results of treatment of carcinoma of the nasopharynx (author's transl)].

Study of survival amongst a group of 101 patients with epithelial tumours of the nasopharynx treated by cobalt irradiation between 1967 and 1972 indicates the prognostic significance of the following factors: the histological type, extension of the tumour, the degree of lymph node involvement, age and sex. The optimal dose is 1,800 to 2,000 rets NSD and should be modified in the light of these factors, and above all the histological type and the tumour category. Cumulative survival for all cases was 36% at 5 years, with a more favourable prognosis in lympho-epitheliomas in comparison with spindle cell epitheliomas.
