This was tested in people. That is the most reliable kind of research we share.
This looked back at stored tumor samples from children, and it is not a treatment.
The short version
Doctors sorted 40 children's brain tumors into three types to see how each type behaved.
What was studied. Researchers looked back at 40 children in Kazakhstan with medulloblastoma, a common childhood brain tumor. The tumors were found between 2015 and 2024. The team studied stored tumor samples under the microscope and with gene testing.
What they found. The tumors fell into three groups: 7 WNT (17.5%), 10 SHH (25.0%), and 23 in a third group (57.5%). Children with WNT tumors were older and lived the longest. The third group was the only one with tumors that had spread at the start, and those children had the poorest long term survival.
What this means, and what it doesn't
What it could mean: Knowing which group a child's tumor belongs to can help doctors judge how it may act over time. This study also shows that ordinary lab tools plus gene testing can sort tumors in places where fancy testing is not part of routine care.
What it doesn't mean: This is not a new treatment, and it is not a cure or a promise for any one child. The team only looked back at old tumor samples. It does not change the care a child gets today, and the findings come from a small group of 40 children in one place.
