Arms of the Study
Arm 1
Experimental
Hypofrac Radiation Therapy
All patients on this study will receive the same type of therapy, 2 treatment hypofractionated radiation therapy. Radiation treatment will start approximately 1-2 weeks after the simulation scan. Prior to each treatment, you will be asked to have a full bladder and empty rectum. You will be asked to take a liquid diet starting the afternoon prior to each treatment, and a laxative (such as Miralax) in the evening prior to each treatment. You will also be asked to take a Fleet's enema about 1 hours prior to the treatment time to ensure that the rectum is empty. To ensure full bladder, you will be asked to drink about 32 oz of water after the enema. This is the same procedure as above for the prep before the simulation scan. Each treatment should take about 10-20 minutes.
