Novel techniques for the treatment of localized prostate cancer: evidence of efficacy?

Radical retropubic prostatectomy and radiation therapy remain the mainstay of treatment for localized prostate cancer. However, with the advent of the Internet, more patients are arriving in physicians' offices questioning novel techniques for their treatment that they otherwise would not have discovered. This paper discusses several of these techniques, including focal cryotherapy, high-intensity focused ultrasound, robotic-assisted laparoscopic prostatectomy, diets, supplements, and hormonal therapy. We also render our opinion on their efficacy for treatment based on the available published studies.
