- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at 26 people already treated, so this was not a trial.
The short version
Doctors looked at a special kind of repeat radiation for people whose meningioma came back.
What was studied. Doctors looked back at records for 26 people whose meningioma grew back after radiation. None of them could have surgery or radiosurgery. All got a repeat radiation given in small pulses, called TMPRT.
What they found. 6 months after treatment, 77% of the people had no tumor growth. For half the people, the tumor did not grow for at least 27.2 months. Three people (12%) had a serious side effect soon after treatment, and 3 people (12%) had one later on.
What this means, and what it doesn't
What it could mean: People who have already had radiation often have few choices left. This study suggests repeat radiation may still be an option for some of them. It may hold the tumor back for a time. Serious side effects were not common in this small group.
What it doesn't mean: This is not a cure. It was not a trial. Doctors just looked back at charts from one hospital. Only 26 people were included, so the results are not certain. Many tumors did grow again over time. This does not tell you if repeat radiation is right for you. Ask your own care team.
