This was tested in people. That is the most reliable kind of research we share.
This was a small look back at people already treated, not a real trial, so we do not yet know if it works.
The short version
Doctors looked back at 10 people whose meningioma kept growing after surgery and radiation, and tried a treatment that sends radiation to the tumor through the blood.
What was studied. One hospital reviewed the records of 10 patients with a meningioma that kept growing after surgery and radiation therapy. All of them had been given the radiation treatment, and the team checked 21 tumor spots with scans before and after.
What they found. Doctors could judge the result in 19 of the 21 tumor spots. In 7 of 19 spots, the tumor stayed the same size. In 12 of 19 spots, the tumor kept growing. The amount of radiation a tumor soaked up did not clearly explain which spots stayed stable, but a scan done before treatment did line up with how much radiation the tumor later soaked up.
What this means, and what it doesn't
What it could mean: For people who have run out of options after surgery and radiation, this treatment stopped growth in some tumor spots but not most of them. The scan done before treatment may help doctors estimate how much radiation a tumor will take in. That could help them plan the dose.
What it doesn't mean: This does not mean a new treatment is ready for you. It was a look back at records from only 10 patients at a single hospital. There was no comparison group, so we cannot say the treatment caused the results. It is not proof that this works for meningioma, and it is not a cure.
