title: Carcinoma of the nasopharynx: results of radiation therapy.
abstract: Of a series of 186 patients with nasopharyngeal neoplasm 138 cases were treated with curative irradiation between 1959 and 1978. All cases were reviewed and retrospectively classified according to the TNM system. The 5-year crude survival rate was 39.5 per cent. A better prognosis was found for women and for younger age groups. The degree of neck node involvement had more prognostic value than the extent of the primary tumor. The causes of failure were analyzed. In 35 cases distant metastases were observed.
