Magtrace is a magnetic liquid that mimics how cancer cells spread, according to an Oct. 17 news release from the health system. It is injected at the time of a mastectomy to determine if the cancer has spread to lymph nodes. Unlike liquid dyes, Matrace stays in the system for weeks at a time.
“We do not know if the cancer has spread beyond the milk ducts and therefore potentially to the lymph nodes until we do surgery which is why we typically remove a few lymph nodes at the time of the mastectomy,” Dr. Valerie Brutus, a breast surgeon at St. Vincent’s, said in the release. “Removing lymph nodes after a mastectomy is challenging and is not as accurate. Magtrace allows us to perform the mastectomy, wait for the pathology and then go back to remove the lymph nodes at a later date if necessary.”
Dr. Brutus called Magtrace a “game-changer” for patients with stage 0 breast cancer.
At the Becker's Perioperative Summit, taking place September 14–15 in Chicago, perioperative leaders and healthcare executives will focus on improving operating room efficiency, enhancing patient safety, optimizing staffing and driving innovation across surgical services.
