How to treat low grade malignant meningioma?

summary

Meningioma is a common tumor occurring in meningeal cells, with a high incidence rate. If suffering from this disease, it is very uncomfortable, after the disease, the main symptoms of patients with headache, at the same time can be accompanied by vomiting and vision loss. Generally speaking, meningioma patients will have vomiting at the same time of headache symptoms, and visual impairment will appear later than headache and vomiting symptoms after optic nerve edema caused by persistent intracranial hypertension. Next, how can I treat low-grade malignant meningioma? Let me tell you this.

How to treat low grade malignant meningioma?

First, surgery is the first choice for the treatment of meningioma. The purpose of surgery is to reverse the neurological signs of patients. When the patient has no obvious symptoms and there is a risk of loss of function after total tumor resection, partial resection should be chosen;

Second, surgical resection is the first choice for meningiomas, and total resection is curable in most cases. In order to avoid the aggravation of functional damage after operation, subtotal resection is feasible. Although meningiomas are mostly benign tumors, the overall recurrence rate is still about 15-20%. Most recurrent meningiomas can be resected again. 1. In order to delay the recurrence of grade 2 meningioma, radiotherapy is feasible.

Third: stereotactic radiosurgery is suitable for patients with residual or recurrent tumor, tumor in skull base and cavernous sinus ≤ 3cm. Gamma knife, X-ray knife and particle knife can be selected. Gamma knife is one of the most commonly used and effective treatment methods. Its advantage is that there is no surgical risk and it is safer. Its disadvantage is that the long-term effect remains to be observed.

matters needing attention

Most meningiomas can be cured by total resection, even if they can not be completely removed, they can get a long period of remission. However, some meningiomas are easy to relapse, even if the grade I or II surgical resection, the recurrence rate can reach 9% ~ 32%. Some studies suggest that flow cytometry (FCM) can prevent malignant transformation or recurrence of meningiomas. For example, meningiomas with proliferation index ≥ 20% are prone to malignant transformation or recurrence.
