This was tested in people. That is the most reliable kind of research we share.
Both of these treatments are already in use for this tumor today.
The short version
Surgery and focused radiation both kept these brain tumors under control for years.
What was studied. Doctors looked back at 118 people with a meningioma on a membrane deep in the brain. 67 had surgery and 51 had stereotactic radiosurgery: Radiation aimed at a small target, in one visit or a few. There is no cutting, despite the name. See the glossary radiation first.
What they found. Surgeons removed the whole tumor in 57 of 67 people. In the surgery group, 92.5% had no tumor growth at 5 years. By 10 years it was 81.6%. In the radiation group, those rates were 94.1% and 79.5%. Problems came up in 22.4% of surgery patients, and in one radiation patient.
What this means, and what it doesn't
What it could mean: Both treatments can hold these tumors in check for a long time. Surgery is the main choice for large tumors or ones causing symptoms. stereotactic radiosurgery: Radiation aimed at a small target, in one visit or a few. There is no cutting, despite the name. See the glossary is an option for some small tumors. Your care team picks based on your tumor and your health.
What it doesn't mean: This does not mean one treatment beats the other. Doctors looked back at old records from one hospital. People were not placed into the two groups at random. So the groups may have been different from the start. This is not a promise of a cure. Ask your own team what fits your case.
