- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This looked back at old patient records, and the scan tool is not used in care yet.
The short version
Researchers used MRI scans to estimate a protein level inside brain tumors that came from lung cancer.
What was studied. Researchers looked back at records for 308 people with lung cancer that had spread to the brain. All of them had surgery. In 56 of them, scans and gene tests were used to build a computer model.
What they found. People with high levels of a protein called GAP43 lived a shorter time. The computer model used MRI scans to estimate GAP43 levels. In a separate group of 252 people, a higher score from the scans also went with shorter survival.
What this means, and what it doesn't
What it could mean: Someday a scan might give doctors a clue about the tumor without more surgery. That could help them plan care and talk about what to expect.
What it doesn't mean: This is not a treatment. It does not shrink or slow the tumor, and it is not a cure. The team looked back at old patient records. This kind of study cannot prove cause and effect. The scan tool is not used in regular care. It needs testing in new patients first.
