Glioblastoma (GBM), the most common primary brain tumor in adults, is characterized by low survival rates and a grim prognosis. Current treatment modalities, including extensive surgical resection, chemotherapy, and radiation therapy, often yield limited success due to the brain's sensitivity, leading to significant side effects. Exciting advancements in immunotherapy have recently shown promise in treating various types of tumors, raising hopes for improved outcomes in brain tumor patients. One promising immunotherapy approach is chimeric antigen receptor (CAR) T-cell therapy, which recognizes surface proteins on targeted tumor cells and redirects cytotoxicity towards specific targets. This review aims to discuss the existing research and future prospects for CAR T-cell immunotherapy in treating glioblastoma.
