How far along is this research?
This is a preprint. Other scientists have not checked it yet, so treat it as an early signal rather than an answer.
This is a computer tool tested on stored data, not a treatment people can get.
The short version
This study tested a computer tool, not a new treatment.
What was studied. Researchers built a computer tool called VARION. It sorts a tumor into a group based on gene changes. They tested it on stored data from ten kinds of cancer, covering 2,417 people.
What they found. For 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, a brain tumor, the tool picked the right group 69.5% of the time. It did better on some other cancers, such as 90.2% for bile duct cancer. It was also tried on two more stored data sets and still worked without being retrained.
What this means, and what it doesn't
What it could mean: Nothing about your care changes today. This is a tool for researchers, not something a doctor can use for you. Over time, better sorting tools may help doctors describe a tumor more clearly.
What it doesn't mean: This is not a treatment and not a cure. It was only run on saved data from past patients. No one was treated based on it. It got the brain tumor group right less often than the other cancers. It is a long way from everyday care.
