Collagen Tiles Could Prevent Brain Cancer Recurrence
A clinical trial has found that placing radioactive tiles into the brain cavity at tumor removal dramatically cuts recurrence and extends survival. The ROADS trial, led by MD Anderson Cancer Center, was presented at the 2026 American Society of Clinical Oncology meeting. It is the first randomized Phase 3 study to directly compare this approach with postoperative stereotactic radiation therapy, conducted across multiple centers. The study was sponsored by GT Medical Technologies, maker of the FDA-cleared brachytherapy device used in the trial. Left untreated with radiation, the surgical cavity shows regrowth in 50% to 60% of patients, making some form of postoperative treatment essential. One year after…
