This was done on cells in a lab, not in people. It is a very early step.
This was only tested by computer on stored tissue slides, not in patient care.
The short version
Researchers built a computer tool that looks at tumor tissue pictures and guesses if a gene called EGFR has extra copies.
What was studied. Scientists tested a computer program on stored slide images of 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 tissue. They used three groups of tumor samples, two from public collections and one private set.
What they found. The program found tissue patterns linked to extra copies of the EGFR gene. It did better than the other computer methods the team compared it with. The patterns it picked out matched patterns doctors already know by sight.
What this means, and what it doesn't
What it could mean: Checking EGFR today costs a lot and takes time. These tests are not easy to get everywhere. A tool like this might one day help labs check for the gene change faster and at lower cost.
What it doesn't mean: This is not a treatment, and it is not a cure. It is early work, done on stored tissue slides by computer. No patient was treated or tested using it in real care. Doctors still rely on lab tests to check EGFR. The tool may not work as well in everyday clinics.
