The primary purpose of this study is to compare the quality of life (QOL) reported by prostate cancer patients 2 years after treatment with ultra-hypofractionated post-prostatectomy radiation therapy (also known as stereotactic body radiation therapy \[SBRT\]) versus the self-reported QOL of those treated with moderately hypo-fractionated post-prostatectomy radiation (a current standard of care option).
Conventional or moderately hypo-fractionated radiation therapy are the current standard of care treatment options for men receiving post-prostatectomy radiation therapy. These treatment regimens typically span 4-8 weeks, representing a high burden of therapy, which may result in decreased utilization of salvage radiotherapy, the only potentially curable treatment for men with relapsed disease following prostatectomy. Ultra-hypofractionated radiation therapy (also known as stereotactic body radiation therapy \[SBRT\]) would decrease the total number of treatments to 5, delivered over 2 weeks, w…
Inclusion Criteria: * Men age ≥ 18 with histologically confirmed prostate cancer after radical prostatectomy with a PSA ≥ 0.1 ng/mL * Interval between prostatectomy and planned radiation therapy start date ≥ 6 months * KPS ≥ 70 * Patients with equivocal pelvic lymph nodes on imaging are eligible if the nodes are ≤ 1.5 cm in the short axis (equivocal evidence of metastatic disease outside of the pelvis on standard imaging requires documented negative biopsy) * Ability to complete the EPIC-26 quality of life questionnaire * Ability to obtain tissue from radical prostatectomy specimen for review…
