Brain metastases from prostate cancer: an emerging clinical problem with implications for the future therapeutic scenario.

Brain metastases from prostate cancer (PC) seem to be more frequent than in the past, possibly because advances in the treatment of patients with castration-resistant PC have prolonged their survival. Furthermore, docetaxel (the drug of choice for the first-line treatment of castration-resistant PC) cannot cross the blood-brain barrier and control metastatic foci. However, this problem may be overcome by new active drugs such as cabazitaxel.
