Cardiovascular Morbidity in a Randomized Trial Comparing GnRH Agonist and GnRH Antagonist among Patients with Advanced Prostate Cancer and Preexisting Cardiovascular Disease

Abstract

To our knowledge this is the first prospective study to test cardiovascular outcomes among patients with prostate cancer who received androgen deprivation therapy. No differences in the primary end point were noted between the study arms. However, the secondary end point revealed that patients treated with GnRH agonist experienced significantly more major cardiovascular and cerebrovascular events than those treated with GnRH antagonist. These phase II results suggest that in patients with prostate cancer who have preexisting cardiovascular disease selecting the androgen deprivation therapy modality may differentially affect cardiac outcomes.
