This was tested in people. That is the most reliable kind of research we share.
This was a look back at tumors already taken out in surgery, not a new treatment.
The short version
The spot in the head where a meningioma grows lines up with the gene changes inside it.
What was studied. Researchers studied 740 meningiomas taken from people during surgery. They compared where each tumor grew to the chromosome changes found inside it.
What they found. Tumors at the front and lower part of the skull base were mostly low grade. They had few chromosome changes. Tumors on the upper outer surface of the brain were more often higher grade. Those tumors had more chromosome changes. Tumors on the side of the skull base fell in between the two groups.
What this means, and what it doesn't
What it could mean: Where a meningioma sits may give your care team one more clue about how it may behave. It could add to what the grade and the scans already show. On its own, it does not change your treatment.
What it doesn't mean: This was a look back at tumors that were already removed. It is not a new treatment, and it is not a test you can ask for. It cannot tell you what your own tumor will do. It is not a cure or a promise of one.
