TOPLINE:

Among patients with prostate cancer who received MRI-guided stereotactic body radiation therapy (SABR), more than 80% demonstrated “classic” neurovascular bundle patterns and over 96% showed more than 1-cm separation of internal pudendal arteries from the prostate. These findings indicated that most patients have favorable anatomic patterns that would allow radiation oncologists to minimize radiation to structures involved in erectile function and help reduce patients’ risk for posttreatment erectile dysfunction.

METHODOLOGY:

Erectile dysfunction is a common side effect for men with prostate cancer who undergo SABR. Radiation-related damage to critical nearby structures, such as the neurovascular bundles and internal pudendal arteries, likely contributes to this issue. Identify
