You may qualify if

• History of histologically confirmed, clinical localized adenocarcinoma of the prostate treated with radical prostatectomy with definitive intent.
• Presence of any ONE of the following:; Adverse pathologic features at the time of prostatectomy (positive surgical margin, pathologic T-stage 3-4 disease, pathologic Gleason score 8-10 disease, OR presence of tertiary Gleason grade 5 disease); Documentation of rising prostate-specific antigen on at least two consecutive draws, with the magnitude of prostate-specific antigen exceeding 0.03 ng/mL; Intermediate- or high-risk Decipher genomic classifier score; Identification of prostate cancer in ≥1 lymph node at the time of prostatectomy (pN+ disease)
• CT scan and MRI of the pelvis within 120 days prior to enrollment [note: (a) if patient has medical contraindication to MRI, an exemption will be granted and enrollment can proceed; (b) for patients with PSA <1.0 ng/mL, the treatment planning CT can substitute for a diagnostic CT scan; (c) a low-field, radiation planning MRI can replace the diagnostic MRI if the patient refuses or cannot obtain a high-field MRI].
• Bone scan OR advanced nuclear imaging study within 120 days prior to enrollment for patients with PSA >1.0 ng/mL.
• Age ≥ 18. ~. KPS ≥ 70 and/or ECOG <2.
• Ability to understand, and willingness to sign, the written informed consent

You can't join if

• Patients with any evidence of distant metastases. Note, evidence of lymphadenopathy below the level of the renal arteries can be deemed loco regional per the discretion of the investigator.; Patients with neuroendocrine or small cell carcinoma of the prostate; Prior pelvic radiotherapy
• History of Crohn's Disease, Ulcerative Colitis, or Ataxia Telangiectasia
