- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was an early study of blood samples from people, not a treatment or a test a doctor can offer.
The short version
A simple blood draw may one day help doctors spot brain tumors in children.
What was studied. Researchers looked at 73 blood samples. They came from 23 children with brain tumors and 25 people without cancer. The team studied gene activity inside platelets, which are tiny cells in the blood that help it clot.
What they found. Platelets from children with brain tumors behaved differently than platelets from people without cancer. The difference was strongest in children with fast growing tumors. Using these patterns, a computer model correctly spotted 85% of the children with fast growing tumors. It correctly cleared 92% of the people without cancer.
What this means, and what it doesn't
What it could mean: Today, doctors find and follow these tumors with scans and biopsies. A biopsy needs surgery. This study is an early sign that a blood test might help someday. It is not a test you can ask your doctor for now.
What it doesn't mean: This does not mean a blood test for childhood brain tumors exists. It was one small early study. Only 23 children with tumors took part. It did not test any treatment, and it is not a cure. The researchers say larger studies at more hospitals are needed first. Work like this can take many years to reach regular care, and it may never get there.
