This Study is Evaluating a New Radiation Treatment Technique for Patients Who Have Had Prostate Cancer, Undergone Surgery for Cancer, and Then Have Evidence That Their Prostate Cancer Has Returned.

There is significant, proven use of radiation for recurrent prostate cancer after surgical resection. This treatment typically is delivered over seven and a half weeks of daily treatments, presenting a burden to patients and the health care system. Stereotactic body radiation (SBRT) is a radiation technique in which large doses are delivered over a short period of time. To date there is extremely limited evidence in SBRT for recurrent prostate cancer after surgery, with a significantly growing body of evidence for primary SBRT treatment of prostate cancer in men who opt for non-surgical upfront treatment. Additionally, advances in imaging have allowed better detection of the site of recurrence, and novel artificial intelligence aided daily-adaptive radiation therapy have allowed more precise delivery of radiation doses. This study seeks to evaluate the role of Daily-Adaptive with AI-assisted SBRT in the post operative setting utilizing Ethos Plan Adaptive technology in attempt to maintain control and minimize side effects.
