Adaptive Versus Non-adaptive Radiotherapy and 2 Bladder Filling Instructions for Patients with Intermediate or High Risk Localized Prostate Cancer (ARP)
Sponsor:

Scott Tyldesley

Information provided by (Responsible Party):

Scott Tyldesley

Brief Summary:

The study is being done to compare the side effects between two different radiation techniques, standard non-adaptive radiation therapy vs. daily adaptive radiation therapy and also comparing two different bladder filling instructions to find out if customized bladder instructions may lead to better treatment outcomes.
