Periprostatic Neurolysis in Prostate Cancer

The purpose of this research study is to assess whether inhibiting nerve activity to the prostate delays progression of disease in men with high-risk clinical features for prostate cancer. Prostate cancer has been shown to invade nerves, a mechanism that is thought to be involved in prostate cancer spread in men with high-risk cancer. When nerve activity to the prostate is blocked in mice with prostate cancer, prostate cancer growth and spread are inhibited. In a previous study we showed that doing so in humans was safe and may have anticancer therapeutic effect. In this study we will test whether one versus two injections of nerve blocking agent is more effective at reducing nerves in the prostate and whether it will slow/stop spread of prostate cancer after treatment.
