Men with localized prostate cancer treated with a newer technology, intensity modulated radiation therapy (IMRT), have more than a quarter (26 percent) fewer late bowel and rectal side effects and a statistically improved lower dose of radiation to the bladder and rectum, compared to those who undergo 3D-CRT, according to a randomized study presented at the plenary session October 3, 2011, at the 53rd Annual Meeting of the American Society for Radiation Oncology (ASTRO). Findings also show...

A shorter course of radiation treatment that delivers higher doses of radiation per day in fewer days (hypofractionation) is as effective in decreasing intermediate to high-risk prostate cancer from returning as conventional radiation therapy at five years after treatment, according to a randomized trial presented at the plenary session, October 3, 2011, at the 53rdAnnual Meeting of the American Society for Radiation Oncology (ASTRO). "This long-term study confirms that hypofractionated...

Men who receive a "boost" of proton therapy after receiving a standard course of X-ray radiation therapy have fewer recurrences of their prostate cancer compared to men who did not receive the extra dose of proton radiation, according to a first-of-its-kind study presented November 2, 2009, at the American Society for Radiation Oncology's 51st Annual Meeting in Chicago. The multi-institutional, randomized trial also shows that the high dose treatment is safe for these patients and causes no...
