This was tested in people. That is the most reliable kind of research we share.
This looks back at people who got care doctors can offer today.
The short version
Radiation after surgery kept most of these brain tumors from growing back.
What was studied. Doctors looked back at 50 adults with a WHO grade 2 meningioma. Each one had surgery, then radiation, between 2013 and 2024.
What they found. During follow up, 10 patients died. In 7 people, the tumor grew back in the same spot. At 2 years, 85.0% were alive. At 5 years, 44.8% were alive. The tumor stayed under control in 76.2% at both 2 and 5 years. All deaths and all regrowth happened in people who had tumor left after surgery. Side effects were mild, only Grade 1 to 2.
What this means, and what it doesn't
What it could mean: Radiation after surgery helped hold these tumors in check for many people. Side effects in this group stayed mild. Removing as much tumor as is safe may matter a lot.
What it doesn't mean: This is not a cure and not a promise. It was a look back at records from one hospital. 50 people is a small group. Older age and larger tumors were tied to worse survival, but the study cannot prove what caused each result. It cannot tell you what will happen in your case. Ask your own care team what fits you.
