What Is a Brain Glioma?
Gliomas are the most common type of primary brain tumor, arising from glial cells — the supportive cells of the central nervous system. They account for approximately 80% of all malignant primary brain tumors and can occur at any age, though they are most frequently diagnosed in adults between 45 and 65 years old.
Gliomas are classified by the World Health Organization (WHO) into grades I through IV based on their histological features and molecular characteristics. The grade reflects the tumor's aggressiveness and growth rate:
- Grade I (Pilocytic Astrocytoma): Slow-growing, often curable with surgery alone; most common in children
- Grade II (Low-Grade Glioma): Slow-growing but infiltrative; includes diffuse astrocytoma and oligodendroglioma; tends to progress to higher grades over time
- Grade III (Anaplastic Glioma): Malignant; includes anaplastic astrocytoma and anaplastic oligodendroglioma; requires surgery, radiation, and chemotherapy
- Grade IV (Glioblastoma / GBM): The most aggressive and most common malignant brain tumor in adults; median survival without treatment is 3 months; with optimal treatment, 14–16 months
Modern glioma classification now integrates molecular markers — particularly IDH mutation status, 1p/19q codeletion, and MGMT promoter methylation — which are critical for prognosis and treatment planning.
Symptoms of Brain Glioma
Symptoms depend on the tumor's location, size, and rate of growth. Common presentations include:
- Headaches — often worse in the morning or with position changes; caused by increased intracranial pressure
- Seizures — a presenting symptom in up to 30–50% of low-grade glioma patients
- Cognitive changes — memory problems, difficulty concentrating, personality or behavioral changes
- Focal neurological deficits — weakness, numbness, speech difficulties, or visual disturbances depending on tumor location
- Nausea and vomiting — from elevated intracranial pressure
- Progressive neurological decline — in high-grade gliomas, symptoms worsen rapidly over weeks to months
Diagnosis
Accurate diagnosis requires a combination of advanced neuroimaging and tissue analysis:
- MRI with contrast (gadolinium): The gold standard for glioma imaging; characterizes tumor location, size, extent of infiltration, and relationship to eloquent brain areas
- MR spectroscopy and perfusion MRI: Helps differentiate tumor grades and distinguish recurrence from treatment effects
- Functional MRI (fMRI) and DTI tractography: Maps eloquent cortex and white matter tracts to guide surgical planning and minimize neurological deficits
- Stereotactic biopsy or surgical resection: Provides tissue for histological and molecular diagnosis
- Molecular profiling: IDH1/2 mutation, 1p/19q codeletion, MGMT methylation, TERT promoter mutation, EGFR amplification — essential for WHO 2021 classification and treatment decisions

Treatment Approach for Brain Glioma
1. Surgery (Maximal Safe Resection)
Surgery is the cornerstone of glioma treatment. The goal is maximal safe resection — removing as much tumor as possible while preserving neurological function. Extent of resection is one of the strongest predictors of survival in both low- and high-grade gliomas.
Advanced surgical techniques used at Shanghai's top centers include:
- Awake craniotomy with cortical mapping: Patient remains awake during surgery to allow real-time testing of language, motor, and cognitive function while the surgeon maps and avoids eloquent brain areas
- Intraoperative MRI (iMRI): Real-time MRI during surgery to confirm completeness of resection and identify residual tumor
- 5-ALA fluorescence-guided surgery: Oral 5-aminolevulinic acid causes tumor cells to fluoresce pink under blue light, enabling more complete resection of high-grade gliomas
- Neuronavigation: GPS-like image guidance system for precise tumor localization and surgical planning
- Intraoperative neurophysiological monitoring (IONM): Continuous monitoring of motor and sensory pathways during surgery
2. Radiation Therapy
Radiation is a standard component of treatment for Grade III and IV gliomas, and increasingly used for Grade II gliomas with high-risk features. Options include:
- Standard fractionated radiotherapy: 60 Gy in 30 fractions over 6 weeks (standard for GBM); 54 Gy for lower-grade gliomas
- Hypofractionated radiotherapy: Shorter course for elderly patients or those with poor performance status
- Stereotactic radiosurgery (Gamma Knife / CyberKnife): High-precision single or few-fraction radiation for small, well-defined tumors or recurrent disease; available at Huashan Hospital
- Proton therapy: Available at select centers in China; may reduce radiation dose to surrounding normal brain tissue
3. Chemotherapy
- Temozolomide (TMZ): Standard chemotherapy for GBM; given concurrently with radiation (Stupp protocol) and then as adjuvant therapy for 6 cycles; most effective in patients with MGMT promoter methylation
- PCV regimen (Procarbazine, CCNU, Vincristine): Standard for 1p/19q codeleted oligodendrogliomas (Grade II–III); significantly improves survival
- Bevacizumab (Avastin): Anti-VEGF therapy used for recurrent GBM; reduces tumor vascularity and edema
4. Tumor Treating Fields (TTFields)
TTFields (Optune device) use alternating electric fields to disrupt glioblastoma cell division. When added to standard temozolomide maintenance therapy, TTFields improve median overall survival in newly diagnosed GBM from 16 to 20.9 months. This technology is available at leading centers in Shanghai.
5. Targeted Therapy and Immunotherapy
- IDH inhibitors: Vorasidenib (for IDH-mutant Grade II gliomas) and enasidenib/ivosidenib are emerging targeted therapies showing significant benefit in IDH-mutant gliomas
- EGFR-targeted therapy: Under investigation for EGFR-amplified GBM
- Immunotherapy (checkpoint inhibitors): Clinical trials ongoing; results in GBM have been disappointing to date, but research continues
- CAR-T cell therapy: Experimental; early-phase trials showing promise for GBM
- Tumor vaccines: Personalized neoantigen vaccines in clinical development
