High-grade gliomas are the most common malignant primary central nervous system tumors with poor prognosis. The operation based on the principle of maximum safe resection of tumors, combined with radiation therapy and chemotherapy, is the primary treatment method. This treatment only delays the progression of high-grade gliomas, and almost all patients eventually develop disease progression or relapse. With the development of molecular biology, immunology, and genomics, people have a deeper understanding of the pathogenesis of gliomas. Targeted therapy, immunotherapy, and other comprehensive treatments are expected to become potential treatments for high-grade gliomas. This article reviews the current status of medical treatment of primary and recurrent high-grade gliomas, and the research progress of high-grade gliomas in targeted therapy and immunotherapy.
