Hypopharyngeal carcinoma. Long-term survivors following radical radiation therapy.

In a material of 167 cases with squamous cell carcinoma of the hypopharynx, treated between 1961 and 1971, radical irradiation was administered to 55 patients. Of these latter patients the 3- and 5-year survival rates were 36 and 25 per cent, respectively. The lesions of the upper part of the hypopharynx were found to be more curable than those of the lower part. Three cases are presented in detail.
