Stereotactic Body Radiotherapy for Low- and Intermediate-Risk Prostate Cancer.   
ABSTRACT
With over a decade׳s worth of clinical experience to guide stereotactic body radiotherapy (SBRT) for the treatment of clinically localized prostate cancer (PCa), sufficient data exist for robust conclusions to be made regarding its efficacy and the toxicities associated with this treatment. We briefly review the fundamental radiobiological basis of SBRT for PCa and provide a comprehensive synthesis of the medical literature to date, focusing on clinical outcomes and toxicities. When possible, we draw comparisons to comparable data for conventionally fractionated radiotherapy. Finally, a brief overview of technical considerations is presented. Although randomized clinical trials comparing SBRT with conventionally fractionated radiotherapy are underway, the current body of evidence supports the efficacy and safety of SBRT for PCa.
