On the other hand, some patients with pituitary adenoma but lacking signs of endocrine hyperfunction have been treated successfully with radiotherapy alone. Svien and Colby (1967) as well as others have found this to be the case.

This proportion is approached only by the series of Cushing (1912, 1933) and Tönnis (1953) who reported 28% acromegalic patients. No other series has shown a higher percentage: Bailey (1932), 25%; Grant (1948), 14%; Kernohan and Sayr
