Despite significant improvements in diagnostic imaging and neurosurgical techniques, the current treatment modalities for high-grade gliomas are inadequate. As such, the median survival for most patients with GBM is on the order of months, even after cytoreductive surgery, radiation and chemotherapy. Fewer than 3% of GBM patients are still alive at 5 years after diagnosis. A rising incidence has been reported for GBM, and the survival rate for patients with GBM has not shown improvement in the last two decades. For this reason exploring novel therapies for the treatment of GBM is warranted.
