Image-guided adaptive radiation treatments reduce short-term side effects for patients with prostate cancer

A technique that uses imaging technology as a guide can make radiation therapy safer for patients with prostate cancer by helping clinicians accurately aim radiation beams at the prostate while avoiding nearby tissue in the bladder, urethra, and rectum. That is the finding of a thorough analysis of all published clinical trials of the technique, called magnetic resonance–guided daily adaptive stereotactic body radiotherapy (MRg-A-SBRT). The analysis is published online in Cancer.
