1. What are the early symptoms of glioma?
Early symptoms of brain gliomas depend on the tumor's location and size.
2. How are gliomas graded?
Brain gliomas are classified into grades I–IV according to World Health Organization standards.Grades I–II are low-grade and grow relatively slowly;grades III–IV are high-grade.
3. What are the surgical treatment options for cerebral glioma?
The surgical principle for brain gliomas is safe, maximal resection—removing as much of the tumor as possible while preserving neurological function.
4. What is minimally invasive treatment for glioma?
Minimally invasive treatments for brain gliomas include stereotactic biopsy for definitive diagnosis, stereotactic radiotherapy for precise irradiation of the lesion, and laser interstitial thermal therapy (LITT), which uses optical fibers to deliver thermal energy and ablate the tumor.
5. Why are radiotherapy and chemotherapy administered after glioma surgery?
The standard postoperative treatment regimen for high-grade glioma involves concurrent chemoradiotherapy followed by adjuvant chemotherapy.Temozolomide is administered concurrently with radiotherapy, followed by continued adjuvant chemotherapy.
6. What progress has been made in targeted therapy and immunotherapy for gliomas?
Bevacizumab can alleviate tumor-associated edema and related symptoms.Targeted drugs for IDH mutations are currently under clinical investigation.
7. What should patients with brain glioma pay attention to in daily life?
Regular medication and scheduled follow-up head MRI scans are required postoperatively.Control seizures and avoid driving or high-risk activities.Maintain a regular daily routine and engage in moderate physical activity to strengthen the body.Prevent infections.
