Doctors test early surgery to stop brain tumors from coming back

This study aims to find out if operating on brain tumors earlier—after initial treatment but before they visibly return—is safe and more effective than waiting. It will compare outcomes for 40 adults who have this early surgery against those who have surgery at a different time or no further surgery. The goal is to help doctors understand when surgery provides the most benefit to patients who still have visible tumor after chemotherapy or radiation.
