Diagnosis and management of acromegaly in 2014 (update from 2012)

Abstract

In this update to the 2012 summary, the current diagnostic and therapeutic approaches to acromegaly are reviewed. The goals of therapy are to control excess growth hormone (GH) secretion and tumor growth, and to limit, if not reverse, the long-term medical consequences and risk for premature mortality associated with acromegaly. Surgery is the preferred primary therapeutic option because it can lead to rapid reductions in GH levels and prevent mass effects from local tumor growth. Use of a somatostatin receptor ligand (SRL) preoperatively to improve surgical outcomes has not been substantiated. Medical therapy, including SRLs, dopamine agonists, and the GH receptor antagonist pegvisomant, is used most often in an adjuvant, secondary role for patients in whom surgery has been unsuccessful. Radiation therapy is most commonly recommended in the setting of failed surgery and lack of adequate control with medical therapy. A role of primary medical therapy for de novo patients has been proposed, particularly with SRLs. Using a multimodality approach, successful management of the disease and associated consequences should be achieved in the majority of subjects.
