High-dose intensity modulated radiation therapy for prostate cancer

The trend in prostate cancer radiation over the past several years has been to increase the dose to the gland while minimizing the dose to normal tissues. Intensity modulated radiation therapy is a computer-driven treatment planning and delivery system that has shown promise in improving disease-free outcome while decreasing the associated gastrointestinal and urinary complication rates. This technique continues to evolve, working toward image-guided radiation therapy, which is adjusted daily for positional and architectural changes of the gland.
