Castration-Refractory Prostate Cancer: New Therapies, New Questions
December 15, 2010
Resistance to androgen deprivation is an ominous milestone in the natural history of metastatic prostate cancer:this disease state, now referred to as castration-refractory prostate cancer (CRPC), is historically associated with a median survival of less than two years. Until recently, only docetaxel (in combination with prednisone or estramustine) demonstrated a benefit in overall survival vs comparator therapy with mitoxantrone plus prednisone.[1,2] However, in the past year, compelling data in support of several promising new treatments for CRPC have been reported. The new data offer evidence-based treatment options, but also raise many questions for patient management and future clinical research.
