Clinical Trial Summary
This study is a large, prospective, pragmatic, controlled comparison of patient-centric
outcomes [quality of life (QOL), toxicity, and disease control] between parallel cohorts of
men with prostate cancer treated simultaneously at proton therapy facilities and at
geographically similar conventional (photon-based) radiation facilities using
intensity-modulated radiation therapy (IMRT) techniques.

Enrollment Eligibility
Inclusion Criteria:
- Diagnosis of adenocarcinoma of the prostate.
- 30-85 years of age at the time of consent with a life expectancy estimation (LEE) of ≥
8 years.
- Localized prostate cancer, as confirmed by staging with PSA, biopsy, Gleason score,
DRE with or without mpMRI, and clinical stage.
- Very low-risk, low-risk, intermediate-risk, or high-risk disease based on NCCN
Prostate Cancer Risk Group Guidelines and Joint AUA/ASTRO/SUO Guidelines.
- If patient has high-risk disease, nuclear medicine bone imaging must be performed to
document the absence of overt metastatic disease in bones.
- ECOG/Zubrod Performance Status 0 - 2.
- Candidate for definitive prostate radiotherapy (either IMRT or proton).
- If patient is to be treated with IMRT, all treatment must be planned with IMRT; if
patient is to be treated with protons, all treatment must be planned with protons
(including pelvic nodes if treated).
Exclusion Criteria:
- Findings of metastatic disease (nodal or distant, N1 or M1).
- Very high-risk prostate cancer based on NCCN Prostate Cancer Risk Group Guidelines and
Joint AUA/ASTRO/SUO Guidelines.
- Prior procedures for treatment of prostate cancer, such as radical or robotic
prostatectomy, high-intensity focused ultrasound, cryosurgery, or focal prostatectomy
[note that procedures used for benign prostatic hyperplasia symptoms, such as
transurethral resection of the prostate (TURP) and GreenLight Laser Therapy, are
acceptable].
- Previous prostate cancer treatment with the exception of ADT according to NCCN
guidelines.
- History of invasive rectal malignancy or other malignancy in the true pelvis (e.g.
bladder, rectum, or reproductive organs), regardless of disease-free interval.
- Active inflammatory bowel disease (i.e., patients requiring medical interventions or
who are symptomatic).
- Prior pelvic RT for any reason.
- Documented lack of psychological ability or general health permitting completion of
the study requirements and required follow-up.
- Documented diminished capacity to understand the risks and benefits of participation
in research and to autonomously provide informed consent.
In addition, because the embedded randomized controlled trial compares fractionation
schemes, patients who are receiving pelvic node irradiation may not be enrolled on the
randomized controlled trial.
