Acromegaly Clinical Trial
Official title:
A Prospective, Randomized Trial of Preoperative Lanreotide Treatment in Acromegalic Patients With Macroadenomas
Previous studies addressing preoperative somatostatin analogs (SSA) treatment and subsequent surgical cure rates are conflicting, reporting a benefit, or no difference between groups. And most reported studies were rather small and were made in retrospect, we conducted a prospective, randomized study to investigate whether 4-month preoperative lanreotide treatment would improve the surgical cure rate of newly diagnosed acromegalic patients with macroadenomas. The investigators also aimed to investigate whether there were differences in the incidence of surgical complications, and duration of neurosurgical hospital stay.
