Sound waves help chemo reach brain tumors in early trial

This small study tested whether a device using focused ultrasound can safely open the blood-brain barrier in patients with high-grade glioma (a type of aggressive brain cancer). The goal was to allow standard chemotherapy to reach the tumor more effectively. Only 3 patients were enrolled, and the study focused on safety and whether the barrier could be opened repeatedly. This is not a cure, but a way to improve existing treatment.
