Clinical trials for a novel treatment for patients with glioblastoma, a deadly form of brain cancer, have shown rapid success, with some patients experiencing a dramatic decline in tumor size just days after their first treatment course.

Researchers from the Mass General Cancer Center, Massachusetts, have shared the results for the first three patients in a clinical trial of CAR-T cell therapy for glioblastoma.

CAR-T cell therapy, or CAR-T for short, won the Nobel Prize in Medicine, and works by using a patient's own immune cells to fight cancer. It's currently the most personalized way to treat the disease.
