Meningioma is a benign brain tumour with a good prognosis and response to treatment. Often, a lump causes no symptoms and is discovered incidentally on the MRI. Doctors use several treatment strategies. For small tumours - surveillance tactics. For more sizable tumours, surgical removal and subsequent radiation therapy. Sometimes the doctor might recommend chemotherapy to shrink the tumour.
A meningioma is a meninges growth covering the brain and spinal cord. As a rule, it is a benign and slowly growing tumour.
Meningiomas are a fairly common disease among all benign brain tumours. However, rarely, it can become cancerous. In terms of prevalence, the disease accounts for 25% of all primary brain neoplasms. Statistics say that it is more common in women. Approximately 97 out of 100,000 people will be diagnosed with the disease.
According to the degree of malignancy, neurosurgeons divide meningiomas into three types:
- Grade 1 is a typically benign tumour that grows slowly. Approximately 80% of cases are of this type.
- Grade 2 is an atypical bump but not yet cancerous. It grows faster than the first type and is more resistant to treatment. It accounts for about 17% of cases.
- Grade 3 - anaplastic, or malignant (cancerous) neoplasm, proliferates quickly and spreads metastases. Occupies about 1.7% of cases.
Symptoms of meningioma develop gradually and are divided into the following categories:
- Cerebral symptoms: headache, which worsens over time; nausea and vomiting; memory impairment; mood changes; weakness in the arms or legs.
- Local symptoms occur when the tumour presses on specific brain structures, including loss of vision, double vision, impaired smell, hearing, speech problems, paresis and convulsions.
To treat meningioma, doctors use several methods or a combination of techniques. In the first stage (small growth and doesn't compress brain structures), it is enough to observe the tumour; if it is more extensive, grows fast or compresses surrounding tissues, it is surgically removed. Stage 2 and 3 meningiomas are treated by neurosurgeons (surgery to remove the tumour) and neuroradiologists (stereostatic radiosurgery, conventional radiation therapy, proton beams). Finally, doctors use CyberKnife when the tumour is difficult to access, or the operation is impossible.
In most cases, the prognosis is favourable. With complete resection (removal) of the tumour, 80% are cured. The 5-year survival rate for grade 1 meningioma is more than 95%, grade 2 - almost 82%, and grade 3 - 46.7%. However, the disease can recur in 3% if it is a benign meningioma with an atypical tumour - in 38%, with a malignant neoplasm, the chance of tumour recurrence is 78%.
