Brief Summary
This is a single-arm phase II prospective trials that is recruiting 100 participants. The study population that is being investigated are patients with localized high-risk or node-positive prostate cancer. Participants will receive external beam radiotherapy as a moderately hypofractionated boost to the prostate with pelvic radiation therapy. Androgen deprivation therapy will be prescribed at the discretion of the treating physician as per standard of care.

Outcome Measures
Primary Outcomes (1)
Acute Grade >2 Gastrointestinal Toxicity
Acute (less than or equal to 90 days) toxicity will be evaluated by using prospective follow-up and grading according to the latest version of the Common Terminology Criteria for Adverse Events (CTCAE) v5.0.
Baseline to 5-year follow-up
Secondary Outcomes (8)
Patient-reported quality-of-life assessed by EPIC-26
Baseline to 5-year Follow-up
Measure the severity of lower urinary tract symptoms during the study
Baseline to 5-year Follow-up
Graded criteria based on CTCAE version 5.0 for acute genitourinary toxicity and late genitourinary and gastrointestinal toxicity
Baseline to 5-year Follow-up
Measure of oncologic outcomes
