Malignant gliomas are a set of tumors that can arise anywhere in the brain. Tumor cells divide to create a mass, as well as infiltrate into normal brain tissue. The current standard of treatment for malignant gliomas is surgery to remove as much of the tumor as possible, often followed by chemotherapy and radiation. There are, however, many new treatment approaches being evaluated for malignant gliomas.
In the following video, Dr. E. Antonio Chiocca, Chair of the Department of Neurosurgery and Co-Director of the Institute for the Neurosciences at Brigham and Women’s Hospital, describes a promising new approach called oncolytic virotherapy. This involves the use of common viruses to treat malignant gliomas. Studies of the herpes simplex virus type 1 have shown that the virus invades tumor cells and destroys them, while also stimulating the immune system to create a vaccine-like effect against the tumor.
