1.What are the early symptoms of central nervous system tumors?
Common symptoms of brain tumors include headache, nausea and vomiting, seizures, limb weakness or numbness, vision loss, and speech impairment.
2.What are the common types of central nervous system tumors?
Brain tumors include gliomas, meningiomas, pituitary adenomas, and acoustic neuromas.Spinal cord tumors include schwannomas, meningiomas, and ependymomas.Medulloblastomas and craniopharyngiomas are common in children.
3.What are the surgical treatment methods for central nervous system tumors?
The surgical goal is the maximal safe resection of the tumor.Microsurgical techniques allow for the precise separation of the tumor from normal tissue, and intraoperative neurophysiological monitoring helps preserve vital functions.
4.What is minimally invasive treatment for central nervous system tumors?
Stereotactic biopsy is used to obtain a pathological diagnosis.Stereotactic radiotherapy (e.g., Gamma Knife) treats small tumors.Neuroendoscopic transnasal surgery is used to remove skull base tumors.
5.Why are radiotherapy and chemotherapy needed after CNS tumor surgery?
Postoperative adjuvant radiotherapy for high-grade tumors can reduce the rate of local recurrence.Chemotherapy is used for specific types, such as medulloblastoma and glioma.Combined radiotherapy and chemotherapy improve treatment outcomes.
6.How do patients with central nervous system tumors recover function after surgery?
Systematic physical therapy, occupational therapy, and speech therapy are required postoperatively.Limb function training helps restore muscle strength and coordination.Cognitive training improves memory and attention.
7.How is follow-up conducted after treatment for central nervous system tumors?
Undergo regular post-operative MRI follow-ups to monitor for recurrence; the frequency is determined by the tumor type.Monitor for changes in neurological function.Perform cerebrospinal fluid analysis to rule out dissemination.
