This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at surgeries people already had, so this is not a new treatment.
The short version
Doctors looked back at surgeries for a brain tumor called a meningioma to see who had it come back.
What was studied. A hundred and fifteen people had surgery for a CNS WHO grade: A number from 1 to 4 for how a tumor is likely to behave. Since 2021 it is written in plain numbers, not Roman ones. Gene results can set it too. See the glossary I parasagittal meningioma. This tumor grows next to a large vein at the top of the head. The surgeries took place from 2005 to 2025.
What they found. The tumor came back in 16 patients, which was 13.9%. On average it came back about 50.1 months after surgery. Also, 12 patients, or 10.4%, had a problem caused by the surgery itself.
What this means, and what it doesn't
What it could mean: The doctors found clues about who is more likely to have the tumor return. How much of the tumor was removed mattered. So did how far the tumor grew into the big vein nearby. A surgeon may weigh clues like these when planning an operation.
What it doesn't mean: This is not a new treatment, and it is not a cure. The doctors simply looked back at records of surgeries already done at one center. Results could be different at other hospitals or for other people. It does not tell you which choice is right for you. Your own care team has to decide that with you.
