Post-prostatectomy Radiation Therapy--Moderate Versus Ultra-hypofractionated (Also Known as Stereotactic Body Radiation Therapy [SBRT])

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, which would greatly reduce treatment burden.
