OC-0035: Catheter displacement and dosimetry for single fraction MRI guided focal prostate HDR brachytherapy

Single fraction multimodal image guided focal salvage high-dose-rate brachytherapy for recurrent prostate cancer

PURPOSE We present a novel method for treatment of locally recurrent prostate cancer (PCa) following radiation therapy: focal, multimodal image guided high-dose-rate (HDR) brachytherapy. MATERIAL AND METHODS We treated two patients with recurrent PCa after primary (#1) or adjuvant (#2) external beam radiation therapy. Multiparametric magnetic resonance imaging (mpMRI), choline, positron emiss...

Systematic Review of Focal Prostate Brachytherapy and the Future Implementation of Image-Guided Prostate HDR Brachytherapy Using MR-Ultrasound Fusion

Prostate cancer is the most common malignancy found in North American and European men and the second most common cause of cancer related death. Since the practice of PSA screening has become common the disease is most often found early and can have a long indolent course. Current definitive therapy treats the whole gland but has considerable long-term side effects. Focal therapies may be able ...

Displacement of neurovascular bundles before and after MRI-guided prostate brachytherapy

INTRODUCTION MRI-guided prostate brachytherapy is feasibile and is efficacious for early-stage prostate cancer. The current standard of practice is to attempt to reduce radiation doses to the bilateral neurovascular bundles (NVBs) adjacent to the prostate gland in order to prevent possible erectile dysfunction (1-4). It has been demonstrated MRI can visualize the NVBs, and hence should be usefu...

Practical considerations for prostate HDR brachytherapy.

PURPOSE A process for prostate high-dose-rate (HDR) brachytherapy was developed and implemented successfully in the community hospital setting. The practical aspects of the program are reviewed and may serve as a foundation for clinics interested in offering this clinical service. METHODS AND MATERIALS A generic needle distribution geometry was established to accommodate target volumes of var...
