The short version
Doctors want to know if blood taken from veins inside the brain can tell them what surgery can.
Who this trial is for. This trial is about a brain tumor called high-grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary. It tests if taking blood from veins inside the brain is safe, and if that blood gives the same kind of details as a tumor sample taken in surgery.
Where it stands. The trial is looking at two things. First, is this blood draw safe? Second, does it tell doctors as much as a surgery sample? The trial has not reported results yet, so we do not know the answers.
What this means, and what it doesn't
What it could mean: Someday, this could give doctors another way to learn about a tumor. For now, it is still being tested. If you have a high-grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary and want to know more, you could ask your care team about it. The trial team decides who can join.
What it doesn't mean: This does not mean a blood draw can replace surgery today. A trial is a test, not a proven treatment. Being in a trial does not promise you will be helped. This is not a cure.
