- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was a look back at scans people already had, and the tool is not in use in clinics yet.
The short version
Doctors tested a way to use brain scans to tell if a lung cancer has a gene change that makes some drugs stop working.
What was studied. Researchers looked back at records from 301 people with non-small cell lung cancer that had spread to the brain. They studied MRI scans of each brain tumor plus a 5 mm band of tissue around it, then built computer models to predict the T790M gene change.
What they found. The model that split the scanned area into three smaller zones predicted the gene change better than models using the tumor alone. Adding basic patient details to that model made it better still. Models built only on patient details, or on simpler scan measures, did not do as well.
What this means, and what it doesn't
What it could mean: This gene change matters because it can make some lung cancer drugs stop working. Doctors usually check for it with a tissue or blood test. If this scan tool holds up in more studies, it might one day give doctors another way to check.
What it doesn't mean: This is not a treatment. It does not shrink a tumor, and it is not a cure. The study only looked back at scans that had already been taken. It did not test the tool on new patients as their care was happening. The tool is not available in clinics, and it would need much more study before a doctor could use it for you.
