Study Summary

This trial is testing whether a treatment called SBRT is effective for treating prostate cancer in patients who have an unfavorable intermediate-risk. The researchers will also look at whether the Decipher test can help predict which patients will benefit from more extensive radiation treatment.

Who is the study for?
This trial is for adults with unfavorable intermediate-risk prostate cancer who haven't had prior treatments like chemo, surgery, or hormonal therapy. They should have a life expectancy over 5 years and be able to undergo MRI scans. People can't join if they've had pelvic radiation before, evidence of cancer spread, recent TURP procedures, active second malignancy within the last 2 years (with some exceptions), or a history of Crohn's Disease or Ulcerative Colitis.Check my eligibility
What is being tested?
The study tests if SBRT alone is effective in treating people with certain types of prostate cancer by preventing its return or spread without using ADT. It also evaluates the use of Decipher test results to decide on more extensive radiation treatments.See study design
What are the potential side effects?
Potential side effects from SBRT may include urinary issues such as increased frequency and urgency, bowel changes like diarrhea, fatigue during treatment period, skin reactions in treated area and erectile dysfunction.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Patients with low-intermediate risk Decipher scoresExperimental Treatment1 Intervention
Will receive ultrahypofractionated EBRT to the prostate and seminal vesicles (40Gy in 5 fractions).
Group II: Patients with high risk Decipher scoresExperimental Treatment1 Intervention
Will receive ultrahypofractionated EBRT to the prostate and seminal vesicles (40Gy in 5 fractions) with a boost of up to 45Gy to the dominant intraprostatic lesion as identified on pretreatment MRI plus hypofractionated pelvic EBRT (25Gy in 5 fractions).
