Pharmacological management of acromegaly: a current perspective (original) (raw)

2010, Neurosurgical FOCUS

Acromegaly is a chronic disorder of enhanced growth hormone (GH) secretion and elevated insulin-like growth factor–I (IGF-I) levels, the most frequent cause of which is a pituitary adenoma. Persistently elevated GH and IGF-I levels lead to substantial morbidity and mortality. Treatment goals include complete removal of the tumor causing the disease, symptomatic relief, reduction of multisystem complications, and control of local mass effect. While transsphenoidal tumor resection is considered first-line treatment of patients in whom a surgical cure can be expected, pharmacological therapy is playing an increased role in the armamentarium against acromegaly in patients unsuitable for or refusing surgery, after failure of surgical treatment (inadequate resection, cavernous sinus invasion, or transcapsular intraarachnoid invasion), or in select cases as primary treatment. Three broad drug classes are available for the treatment of acromegaly: somatostatin analogs, dopamine agonists, an...
