Update on castrate-resistant prostate cancer: 2010

Purpose of review Prostate cancer remains a medical dilemma and a major cause of morbidity and mortality in many western countries. It represents the most common cancer in US men, with an estimated 192 280 new cases diagnosed in 2009. The median survival for men with metastatic castrate-resistant prostate cancer is 1-2 years, with improvements in survival seen primarily with docetaxel-based therapies. The purpose of this article is to discuss developments of novel agents in the field of metastatic castration-resistant prostate cancer (CRPC), including new cytotoxic agents, immune-based therapies, circulating tumor markers and targeting agents. Recent findings During this past year, several promising approaches yielded disappointing results in the phase III setting (GVAX); nonetheless, expectations for other agents (Abiraterone, MDV3100, Zibotentan, immunotherapy agents) still remain high. Summary Systemic therapy options are limited in CRPC and survival benefit remains to be seen with the new therapies. Circulating tumor cells continue to provide important prognostic information and will likely become an important aspect of future clinical decision-making.
