title: Systemic management of prostate cancer.
abstract: The objective of this review is to explore different therapeutic options for metastatic adenocarcinoma of the prostate. Orchiectomy, estrogen therapy, synthetic LHRH analogs and possibly antiandrogens are equally effective frontline treatment modalities. Ketoconazole is indicated in emergency situations, but chronic use is prevented by serious idiosyncratic toxicity and by long term complications. Combined androgen blockade (CAB), with leuprolide (or tryptorelin) and flutamide is more effective than single modality treatment in patients capable of strict treatment compliance. Estramustine phosphate may be as effective as CAB and may be the frontline treatment of choice in sexually active patients. Institution of single modality treatment may be delayed until cancer becomes symptomatic. Controversy lingers over whether the institution of CAB at an earlier time may improve progression free survival (PFS) and survival. Research projects of immediate clinical relevance include: comparison of CAB and estramustine; determination of the optimal time for CAB; study of other forms of CAB; and phase II trials of new cytotoxic agents.
