Reduction of dose to or 'sparing' of neurovascular structures during stereotactic ablative body radiotherapy (SAbR) for localized prostate cancer will improve retention of sexual potency, while retaining excellent oncologic control and other secondary health-related quality of life (HRQOL) endpoints. Primary Objectives: • To compare the decline in patient health-related quality of life (HRQOL) instrument-defined erectile dysfunction following stereotactic ablative body radiotherapy (SAbR) with or without neurovascular sparing Secondary Objectives: * Assess acute (within 3 months of treatment) and chronic (\>3 months after treatment) SAbR related GU and GI toxicities, as well as serial impact on HRQOL metrics over time * Assess biochemical progression free survival, local recurrence, distant recurrence, and survival * Evaluate simplified 'practical' secondary HRQOL sexual potency endpoints that can be compared to prior literature. Exploratory Objectives: * Evaluate feasibility of MRI BOLD/TOLD to be integrated as hypoxia monitoring sequences to standard already planned diagnostic and/or treatment planning MRI on the study in five patient pilot. * Evaluate quality of spacer placement and its effect on dose to neurovascular structures * Evaluate rate local recurrence in the area of sparing adjacent to the neurovascular elements by biopsy in those with biochemical progression.
NCT01309672
RATIONALE: Androgens can cause the growth of prostate cancer cells. Antiandrogen drugs, such as abiraterone acetate, may lessen the amount of androgens made by the body. It may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying the side effects and how well abiraterone acetate works in treating patients with prostate cancer who have undergone initial hormone therapy.
