About this trial
For this study, high risk prostate cancer patients with lower risk ARTERA scores will be treated with 6 months of Androgen Deprivation Therapy (ADT) in conjunction with dose escalated radiotherapy to the prostate and nodes. Specifically, patients enrolled in this study will undergo one of several dose-escalated forms of radiotherapy which would include SBRT with or without a brachytherapy boost.

Treatments tested in this trial
Androgen Deprivation Therapy (ADT)
DrugADT will be delivered with monthly Degarelix, or Leuprolide injections or daily Relugolix pills which are all standard ADT interventions.
Radiotherapy
RadiationDose-escalated radiotherapy.
Treatment groups
Trial outcomes
Primary outcomes
5-Year Cumulative Incidence of Distant Metastases
Incidence of distant metastases (DM). DM is defined as the first occurrence of radiographic or biopsy-confirmed distant metastatic disease.
Secondary outcomes
Distant Metastasis-Free Survival (DMFS)
Defined as the time from study enrollment to the first occurrence of distant metastasis or death from any cause, whichever occurs first.
Time to Biochemical Failure
Time to biochemical failure will be measured from study enrollment to the date when the Phoenix criterion (PSA nadir + 2 ng/mL) is first met.
Overall Survival (OS)
Defined as the time from study enrollment to death from any cause.
Change in Expanded Prostate Cancer Index Composite-26 (EPIC-26) Score
26-item survey assessing prostate cancer-related symptom domains. Each item is rated on a Likert score. The raw score is the sum of responses and is converted to a standard score from 0-100, where higher scores indicate greater quality of life.
