Radiation After Surgery or Close Watching for Low-Risk Meningioma
Original title: Comparing Radiation After Surgery to Observation After Surgery in Patients With Clinical Low-Risk, Molecular High-Risk Meningioma, and Evaluating Observation After Surgery in Patients With Clinical and Molecular Low-Risk Meningioma
How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
This is a large, late stage trial comparing two treatments doctors already use.
Status: Not yet recruiting. It has not opened yet. Ask your care team to watch for it if it looks like a fit.

The short version
This trial tests whether radiation after surgery helps more than close watching.
Who this trial is for. This trial is for people who had surgery for a grade 1 or grade 2 meningioma and have a low clinical risk. It uses a tumor test to sort people into groups, then compares radiation after surgery with close watching.
Where it stands. The trial is measuring how long people go without the tumor growing or coming back. That answer is not in yet. The trial has not reported results.
What this means, and what it doesn't
What it could mean: Doctors already use tumor grade and how much tumor was removed to choose what comes next. This trial asks if a tumor test can help make that choice better. If this sounds like your situation, you can ask your care team about it.
What it doesn't mean: A trial is a test, not proven care. Joining one does not mean you will be helped. Radiation can cause side effects. This is not a promise of a cure.
