They include a wide variety of histological types and grades of malignancy as well as genetic heterogeneity. This creates a diagnostic complexity that requires a combined approach to incorporate imaging, histopathology, and genomic methods. Treatment is based on morphologic and, increasingly, molecular data, and often involves a multidisciplinary approach with surgery, irradiation, and chemotherapy as well as targeted therapies. In spite of the recent advances in diagnosis and treatment, prognosis of the most common primary neoplasms—high-grade gliomas—remains poor.
