This was tested in people. That is the most reliable kind of research we share.
This was only tested on past patient records, and doctors do not use it yet.
The short version
Researchers built a computer tool that looks at brain scans to guess if a common chemo drug will work.
What was studied. Researchers used past records and MRI scans from 314 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 at four medical centers. They built a computer tool to guess, before treatment, if the chemo drug temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary would work.
What they found. The computer tool did a good job of telling apart people the drug helped from people it did not. It did even better when paired with a tumor gene test called MGMT promoter methylation: MGMT is a gene whose protein repairs damage to a tumor's DNA. Methylation turns it down. Your report says how much, and your team uses that when they choose chemotherapy. The line between high and low is not settled. See the glossary. This paired tool beat either one alone in each group of patients it was checked on.
What this means, and what it doesn't
What it could mean: The researchers hope a tool like this could one day help doctors know early if this chemo will work. People it likely won't help might be spared chemo that does them no good. People at higher risk might get stronger treatment.
What it doesn't mean: This tool is not ready for doctors to use. It was built by looking back at old records, not tested in a new trial. It does not change how anyone is treated today. It is not a new treatment, and it is not a cure. Talk with your care team about your own treatment.
