This was tested in people. That is the most reliable kind of research we share.
This is a report on one patient, and no treatment was tested.
The short version
Doctors found a gene change in a meningioma that is almost never seen in this kind of tumor.
What was studied. This is a report on one patient, a 69-year-old man. He had two masses in his brain. Doctors tested one of them, a meningioma, with several lab methods.
What they found. One mass was a meningioma with a gene change called IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary R132H. Three different lab tests confirmed it. This change is very rare in meningioma. The most common gene problem in these tumors is the loss of one copy of chromosome 22. In the few cases reported before, the outlook may have been better.
What this means, and what it doesn't
What it could mean: Gene testing can sometimes turn up a rare change in a meningioma. The authors think tumors like this may deserve their own group. Drugs that target IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary are raised as a possible future option, not a current one.
What it doesn't mean: This is one patient's story, not a study of many people. No treatment was tested here. Drugs aimed at IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary have not been shown to work in this tumor. Bigger studies are still needed first. This is not a cure, and it does not change care today.
