The histories of 32 patients with craniopharygioma who had received radiotherapy after surgery were reviewed to assess the effect and adequacy of the radiation dose. The survival rates were 69% at 5 years and 60% at 10 years in all cases, but depended markedly on sex and age. Symptomatic improvement and histological changes in the irradiated tumor are also discussed. Radiation therapy with a dose ranging from 5500 to 6000 rads (approximately 1700 rets) after the first surgical intervention definitely improves the prognosis.
