Study Confirms Benefits of IMRT for Localized Prostate Cancer

Intensity Modulated Radiation Therapy (IMRT) is better than conventional Conformal Radiation Therapy (CRT) for reducing certain side effects and preventing cancer recurrence.

A treatment for localized prostate cancer known as Intensity Modulated Radiation Therapy (IMRT) is better than conventional conformal radiation therapy (CRT) for reducing certain side effects and preventing cancer recurrence, according to a study published in the April 18, 2012 issue of the Journal of the American Medical Association. IMRT is one of the services offered at The Prostate Center.

The study, conducted by scientists at the University of North Carolina, also showed IMRT to be as effective as proton therapy, a newer technique that has grown in popularity in recent years. 
Study scientists report that compared to CRT, IMRT was associated with fewer diagnoses of gastrointestinal (GI) symptoms, such as rectal bleeding or diarrhea, hip fractures and additional cancer therapy, but more difficulty with sexual function. Proton therapy was associated with more GI problems than IMRT. 



In a press release, 
Tim Carey, MD, director of the Sheps Center at UNC, said, “This type of research is critical, comparing one type of treatment with alternatives, so that patients and their providers can arrive at the best decisions for each individual.”

CRT, IMRT and Proton therapy represent three types of radiation, each attempting to deliver radiation treatment to a tumor while minimizing radiation dose to surrounding organs.  You can read more about the study at the UNC Healthcare web site.
