Cytoreductive Prostatectomy in Treating Patients With Newly Diagnosed, Metastatic Prostate Cancer

PRIMARY OBJECTIVES: I. To determine the safety and feasibility of cytoreductive prostatectomy (to remove as much of the primary cancer as possible) in men with newly diagnosed clinical T1-3N1M0 or T1-3N0M1a-b prostate cancer (herein, collectively referred to as metastatic prostate cancer). SECONDARY OBJECTIVES: I. Time to prostate specific antigen (PSA) nadir and castration resistance following cytoreductive prostatectomy and subsequent standard systemic therapy, androgen deprivation. OUTLINE: Patients undergo RARP or conventional open RRP. Immediately following surgery, patients receive standard systemic androgen deprivation therapy. After completion of study treatment, patients are followed up every 90 days for 3 years.
