EurekAlert! -- Preliminary results show that a shortened course of radiation therapy for prostate cancer called stereotactic body radiation therapy (SBRT) provides good PSA response for early-stage prostate cancer and has the same side effects as other treatments, according to a March 15 study in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO). Study authors caution that further follow-up will be necessary to establish that SBRT is as effective in the long term as other proven treatments.
