Malignant transformation in non-functioning pituitary adenomas (pituitary carcinoma).

abstract：CONTEXT:Outcome of acromegaly surgery is assessed by IGF-1 and glucose-suppressed GH, but whether the latter provides additional clinically relevant information when IGF-1 is normal is unclear. The role of GH suppression testing after surgery requires clarification. METHODS:We studied 97 acromegaly patients with norma...
