High-dose stereotactic body radiotherapy (SBRT) for men newly diagnosed with low- or intermediate-risk prostate cancer results in shorter treatment times, low severe toxicity and excellent cancer control rates, according to new research. The findings were presented at the 58th Annual Meeting of the American Society for Radiation Oncology (ASTRO), Sept. 25-28 in Boston. The study is the first large, multi- institutional study of SBRT in prostate cancer with long-term follow-up.
