Image-guided intensity-modulated radiation therapy (IG-IMRT) is a form of radiation therapy to treat prostate cancer. Typically, this treatment requires patients to come in for one-hour radiation therapy sessions five days a week for eight to nine weeks.
The purpose of this study is to evaluate the side effects associated with escalating doses during a shorter course of radiation therapy called ultra-hypofractionated IG-IMRT in men with prostate cancer. This therapy is delivered every other day for a total of five treatments which can be completed within two weeks.
The radiation delivered during ultra-hypofractionated IG-IMRT is a higher, more targeted dose than the conventional approach. By the end of treatment, patients should receive a total radiation dose that is equal to or greater than the standard approach.
