Original title: Functional clustering within glioblastoma identifies a network-integrated subtype with improved survival.

- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was a study of brain scans in people, not a test of any treatment.
The short version
Brain scans found a group of tumors linked with longer survival.
What was studied. Researchers looked at resting brain scans from 190 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 checked how parts of each tumor linked up with seven normal brain networks, and compared them to scans from 347 healthy people.
What they found. Fifty-two of 190 tumors had more than one active zone inside them. People with these tumors lived longer. They also had seizures more often before surgery. These tumors linked more strongly with the brain's own networks.
What this means, and what it doesn't
What it could mean: This may give doctors a better idea of how a tumor will behave. It may also help explain why some people have seizures. It could lead to new ways to group these tumors.
What it doesn't mean: This is not a new treatment. Nobody was given a drug or therapy here. Researchers only looked at brain scans and past records. It does not mean people with these tumors will do well. It is not a cure, and it does not change care today.
