The future in advanced prostate cancer: take your partners or is the last dance for me?

Recent therapeutic initiatives have improved quality of life and survival for patients with advanced prostate cancer. This review focuses predominantly on prostate cancer that has become refractory to standard androgen ablation treatment. Planned trials will answer further questions on the optimal use and sequencing of currently available hormonal agents, cytotoxic therapies, and radiolabeled nucleotides. Future therapeutic advances are likely to come in 2 areas: targeted therapies and response prediction. Molecular targeted agents will be most useful in combination with each other or with established systemic therapies. The selection of combinations will require the application of paradigms targeting key biochemical pathways and specific microenvironments in prostate cancer. Response prediction for individual patients may be assisted by either pretreatment or sequential molecular profiling, or sequential imaging, or biochemical studies that predicate outcome prior to or soon after treatment has been initiated. To bring these advances to the metastatic prostate cancer patient, a series of well-designed clinical trials is needed that integrates the lessons learned through laboratory, translational, and clinical studies in recent years.
