- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This looked back at scans from real patients, but it is a risk tool, not a treatment.
The short version
Researchers used regular MRI scans to sort patients into higher and lower risk groups.
What was studied. Researchers looked back at MRI scans from 473 people with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. They tested the scans in another 82 people from a different hospital.
What they found. A computer split each tumor on the scan into four kinds of zones. Zones that looked dead, and swollen zones around the edge, were tied to shorter survival. Adding these zone scores to age, sex, and a tumor marker made the risk guess more accurate in the second group of 82 people.
What this means, and what it doesn't
What it could mean: One day, a normal MRI might tell your care team more about your risk. That could help you and your doctor plan ahead. No surgery or extra test would be needed.
What it doesn't mean: This is not a treatment, and it is not a cure. The team only looked back at scans that were already taken. The tool has not been tested in a new study going forward. It is not something your doctor can use today.
