This project is a single-arm, prospective study assessing changes in acute patient-reported urinary (GU) and gastrointestinal (GI) quality of life at the 24-month post-treatment time point following magnetic resonance imaging (MRI)-guided or computed tomography (CT)-guided stereotactic body radiotherapy (SBRT) delivered to the prostate bed +/- pelvic lymph nodes. There is no pre-specified target enrollment for patients undergoing standard non-adaptive SBRT. The target enrollment of patients undergoing adaptive treatment is 200 patients. The rate of accrual is expected to be in the range of 40 patients per year.

You may be eligible 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:
1. 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)
2. Documentation of rising prostate-specific antigen on at least two consecutive draws, with the magnitude of prostate-specific antigen exceeding 0.03 ng/mL
3. Intermediate- or high-risk Decipher genomic classifier score
4. 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.

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
