Laser therapy extends glioblastoma survival when more tumor removed, study finds

For decades, a glioblastoma diagnosis has carried a near-certain sentence: aggressive surgery, grueling treatment, and roughly eighteen months of life. Now, a large multi-center analysis offers evidence that a laser threaded through a pencil-width hole in the skull can extend that horizon by six months or more — and send patients home the next day. The study, anchored in fifteen years of clinical refinement at Washington University School of Medicine, suggests that how we intervene in brain cancer, and when, may matter as much as whether we intervene at all.
