“…In 1958, the charged-particle radiosurgery program was expanded to include patients with endocrine and metabolic disorders of the pituitary gland, i.e., acromegaly, Cushing's disease, Nelson's syndrome, prolactinsecreting adenomas and chromophobe adenomas [8,11,13,14,15,16]. ·In the 441 patients with hormone-secreting tumors, the therapeutic goal has been to destroy or inhibit the growth of the pituitary tumor and control hormonal hypersecretion, while preserving a functional rim of tissue with normal hormone-secreting capacity, and minimizing neurologic injury [11,13,15]; an additional 34 patients with nonsecreting chromophobe adenomas were treated to alleviate sequelae of an expanding mass lesion (Table 1).…”
