Malignant gliomas are the most common and malignant brain tumors in adults. The prognosis of patients with malignant glioma is poor, with a median survival time of 12–18 months for patients with glioblastoma multiforme (GBM) receiving a combination of surgery, radiotherapy, and chemotherapy, and a median survival time of 2–3 years for patients with anaplastic astrocytoma.
