Cardiovascular Risk Associated With Androgen Deprivation Therapy
August 15, 2010
Prostate cancer is the second leading cause of cancer-related death among men in the United States. Androgen deprivation therapy (ADT) is a common treatment for prostate cancer. ADT includes gonadotropin-releasing hormone (GnRH) agonists (leuprolide, goserelin, triptorelin), bilateral orchiectomy, and anti-androgen receptor blockers such as flutamide and bicalutamide. Several studies have now shown conflicting evidence that anti-androgen therapy may lead to increased cardiovascular morbidity and mortality.[2-5] None of these studies has provided conclusive evidence for causality or a direct link to cardiovascular disease, but they have proposed that therapy side-effects increase parameters that are similar to those of the metabolic syndrome.
