Study Details

Brief summary:

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.

Interventions and Outcome Measures

Arms

experimental: 1 - Prostate bed only recurrence

Patients with confirmed radiologic recurrence of their prostate cancer in the defined region of the previous prostate surgery - commonly referred to as the prostate surgical bed.

experimental: 2- Pelvic nodal with or without a prostate bed recurrence

Patients who have a radiologic recurrence of prostate cancer in the pelvic node region

Interventions

Daily-adaptive Stereotactic Body Radiation Therapy

Daily-adaptive radiation therapy to two dose levels - one to the area of radiologic recurrent nodal disease, and a lower, prophylactic dose to the standard post-prostatectomy and larger pelvic node fields

Daily-adaptive Stereotactic Body Radiation Therapy

Daily-adaptive radiation therapy to two areas - a high dose to the area of radiologic recurrence, and a lower, prophylactic dose to the standard post-prostatectomy fields

Primary outcome measure

  • Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]) [ Time Frame: 1-2 years ]
  • The primary objective of the full enrollment Phase II component is to report biochemical recurrence free survival (bPFS). [ Time Frame: 5 years ]
