This was tested in people. That is the most reliable kind of research we share.
This is about how doctors grade tumors, not a treatment, and the details were missing, so we scored it low to be safe.
The short version
This study checks a proposed new way for doctors to grade a brain tumor called IDH gene change: A small change in a tumor's IDH gene. Tumors with this change often grow more slowly and may respond to different treatments. Your pathology report says whether your tumor has it. See the glossary astrocytoma.

What this means, and what it doesn't
What it could mean: There is not enough information here to say what this means for you. Nothing here should change your care. If tumor grading matters to you, ask your care team what grading system they use.
What it doesn't mean: This is not a new treatment. It is about how doctors label and grade tumors, not about a new medicine you could take. It is not a promise of a cure. And because the details were missing, nothing here has been checked or confirmed.
