Androgen deprivation therapy (ADT) has been used in the management of prostate cancer for more than four decades. Initially, hormone therapy was given largely for palliation of symptomatic metastases. Following several randomized trials of patients with intermediate- to high-risk prostate cancer that demonstrated improvements in biochemical control and survival with the addition of ADT to external beam radiotherapy, there was a dramatic increase in the use of hormone therapy in the definitive setting. More recently, the safety of ADT has been questioned, as some studies have suggested an association of hormone therapy with increased cardiovascular morbidity and mortality. This is particularly worrisome in light of practice patterns that show ADT use extrapolated to situations for which there has been no proven benefit. In the setting of dose escalation with modern radiotherapy, in conjunction with the latest concerns about cardiovascular morbidity with ADT, the magnitude of expected benefit along with potential risks of ADT use must be carefully considered for each patient.
