This was tested in people. That is the most reliable kind of research we share.
This was a look back at past patient records, not a test of a new treatment.
The short version
This study offers a plan for how often to get MRI scans after surgery for this kind of tumor.
What was studied. Researchers looked back at records for 358 skull base meningiomas that were removed by surgery at two hospitals between 2002 and 2020. They checked how often a tumor grew back enough to need more treatment, then used that to build an MRI scan schedule.
What they found. Tumor growth that needed another treatment happened in 14.1% of patients. People whose tumor was only partly removed had a higher risk of needing more treatment. For a complete removal, the team suggested scans at 3 months, 2, 5, 8, and 10 years. For a partial removal, they suggested more scans: 3 months, 1 year, 18 months, every year from 2 to 8 years, and at 10 years.
What this means, and what it doesn't
What it could mean: If you had surgery for this kind of tumor, this gives your care team a possible plan for how often to scan you. How much of the tumor was removed matters. A partial removal may mean scans more often.
What it doesn't mean: This is not a new treatment, and it is not a cure. It is a look back at records from people already treated at two hospitals. Nothing new was tested in a trial. Other hospitals may not follow this schedule, and your own doctor may choose a different plan for you.
