Intensity-modulated radiation therapy for prostate cancer is cost effective and improves therapeutic ratio.

Radiation therapy is one of the standard treatment options for many prostate cancer patients. Intensity-modulated radiation therapy (IMRT) allows for more conformal dose distributions that can reduce normal tissue toxicity compared with older external beam techniques. There has been a rapid adoption of IMRT between 2001 and 2007 for prostate cancer patients regardless of the patients' race, socioeconomic status or disease risk classification. IMRT is more expensive than older radiation techniques and has an impact on healthcare spending for prostate cancer.
