[Endocrinological evaluation of sellar and suprasellar tumor cases (the 2nd report);--on postoperative pituitary function (author's transl)]

Abstract

Fifty-six cases of sellar and suprasellar tumors were examined endocrinologically before and 3 weeks after surgery. 1) Hyporeactive cases of GH & ACTH were more frequently found in pituitary adenoma (100% and 23% respectively than in craniopharyngioma (86% and 14% respectively) before surgery. 2) GH secretion was impaired 3 weeks after surgery in all the cases. 3) ACTH secretion impaired preoperatively in 5 cases of pituitary adenoma improved in 3 cases 3 weeks after surgery. 4) Hyporeactivity of LH, FSH and TSH was found more frequently after surgery than before. 5) Almost all the cases of tuberculum sellae meningioma were endocrinologically normal before surgery. 6) ACTH, LH, FSH and prolactin secretion in cases of tuberculum sellae meningioma was not impaired after surgery, but TSH secretion in these cases became hyporeative in 4 of 5 cases after surgery.
