Contemporary Management of the Newly Diagnosed Prostate Cancer Patient with Metastatic Disease at Presentation.

PURPOSE OF REVIEW: Androgen deprivation therapy (ADT) has been the standard-of-care (SOC) for metastatic hormone-sensitive prostate cancer (mHSPC) since the middle of the twentieth century. Recently, several practice-changing trials have added new therapy options for these patients. Here we review these studies and discuss guidelines on treatment decision-making.

RECENT FINDINGS: A trio of studies (GETUG-AFU15, STAMPEDE, CHAARTED) combining docetaxel chemotherapy with ADT all showed clinical benefit of the addition. More recently, the LATITUDE and STAMPEDE-Abiraterone studies established yet another new option for up-front treatment of newly diagnosed metastatic prostate cancer, showing significantly prolonged overall survival (OS) and progression-free survival (PFS) compared to ADT alone in men with high-risk mHSPC. With the recent demonstration that adding either docetaxel or abiraterone plus prednisone to ADT significantly improves survival in mHSPC, physicians are confronted by a growing body of clinical data and treatment regimens. Men with high-volume and/or high-risk metastatic disease should not be treated with ADT alone without strong consideration of docetaxel or abiraterone. The choice of a first-line therapy should be made based on risk stratification, patients' comorbidities, toxicities, quality-of-life (QOL) considerations, and cost.
