IMRT Shown to Cause Significantly Less Gastrointestinal Harm

A recent article in the April 18, 2012 issue of The Journal of the American Medical Association (JAMA) reports that proton beam radiation for prostate cancer causes significantly greater gastrointestinal side effects and toxicity than IMRT radiation.

By comparison, a recent report of 5 year data of prostate cancer treated with Cyberknife Radiosurgery shows no grade 3 rectal cancer. Cyberknife radiation is unique in that it is the only radiation delivery system that can continuously monitor movement of the patient and the tumor throughout the entire course of radiation. When the system detects a change in position of the tumor, immediate corrections are made in the treatment to ensure accuracy and reduce dose to the bladder and rectum.
