This was tested in people. That is the most reliable kind of research we share.
This tool was only tested by looking back at old patient records, not in a live trial.
The short version
Researchers built a computer tool that reads tumor slides to guess who may later get brain tumors.
What was studied. Researchers built a computer tool called BraMARS. It looked at routine stained tissue slides from people who had surgery for limited-stage small-cell lung cancer.
What they found. The tool sorted people into a higher risk group and a lower risk group. Those two groups went on to have different outcomes, including how long they lived. In a test that replayed old patient records, the tool could have cut preventive brain radiation for 19.3% of the people it called low risk. It also flagged more of the people it called high risk, by 84.4%.
What this means, and what it doesn't
What it could mean: One day, a tool like this might help your doctor decide if you need preventive brain radiation. It might also point out who should get brain scans more often.
What it doesn't mean: This is not a treatment, and it is not a cure. The tool only looked back at old patient records. It has not been tested in a real trial where doctors used it to make choices. It is not something you can ask for at a clinic today. It also cannot tell any one person that they will or will not get brain tumors.
