About this trial

This study is being done to answer the following question: Is the strategy to give higher doses of radiotherapy treatment over a shorter period of time using special equipment and fewer treatments (also known as Stereotactic Body Radiation Therapy or SBRT) as effective as usual external radiation therapy given with a brachytherapy boost (which involves radiation sources inserted directly into the prostate)?

Eligibility criteria

Qualifiers

Histologically confirmed adenocarcinoma of the prostate diagnosed within the last 9 months

2 or 3 Intermediate Risk Factors (IRFs): cT2b-cT2c, Gleason 7 (grade group 2 or 3), and/or PSA 10-20 ng/ml;

Gleason 4+3 (grade group 3)

> 50% biopsy cores positive

Disqualifiers

Prior pelvic radiotherapy

Contraindication to radical prostate radiotherapy (e.g. connective tissue disease or inflammatory bowel disease)

Anticoagulation medication (if unsafe to discontinue for gold seed insertion or brachytherapy implant) and/or prior or current bleeding diathesis

Prior steam vaporization (Rezum), transurethral resection of the prostate (TURP), prostatectomy (simple or radical), or any ablative therapy to the prostate (cryotherapy, HIFU, TULSA, focal laser ablation, photodynamic therapy)
