Medical University of South Carolina Performs World's First Prostate Cancer Surgery Using Blu Build Brachytherapy System

RICHLAND, Wash., Jan. 29, 2019 (GLOBE NEWSWIRE) -- – Isoray, Inc. ISR, a medical technology company and innovator in seed brachytherapy powering expanding treatment options throughout the body, today announced that Hollings Cancer Center at the Medical University of South Carolina (MUSC) has successfully completed the world's first prostate cancer surgery using the pioneering Blu Build real-time Cesium-131 brachytherapy (internal radiation therapy) delivery system. 

Dr. David T. Marshall, a professor of Radiation Oncology and Urology, and medical director of the Clinical Trials Office at the Hollings Cancer Center, performed the surgery on October 26, 2018. "No two patients are exactly alike. What Blu Build provides physicians is a real-time means to individually customize and deliver a precise placement of Cesium-131 brachytherapy seeds tailored to the patient's anatomy and cancer as the physician is seeing it in the operating room at the time of surgery," Dr. Marshall said. Since the successful completion of the first surgery, Dr. Marshall has used Blu Build to treat 12 additional prostate cancer patients.

"Here at Hollings Cancer Center, we are proud to continue our legacy as innovators dedicated to bringing the very best in medical advancements and care to our patients," concluded Dr. Marshall.

Isoray's disposable, single use, next-generation device is also unique in that it is the first to be handheld offering a new level of maneuverability.

Blu Build is believed to be the first new delivery system designed specifically for prostate brachytherapy in years. The delivery system conveys additional benefits as it enables doctors to deliver a high radiation dose to the targeted prostate cancer and limits the impact on the surrounding areas compared to other treatment options.

Isoray CEO Lori Woods said this is an important development for prostate cancer patients and physicians. "Blu Build provides each patient personalized treatment for their specific situation with the unique treatment benefits of Cesium-131 brachytherapy. This is an important step forward in prostate cancer treatment."

Isoray is the only producer of Cesium-131 brachytherapy, which expands internal radiation treatment for prostate and difficult to treat brain, gynecological, lung, head and neck, esophageal, and abdominal wall cancers.
