This was tested in people. That is the most reliable kind of research we share.
This was a look back at past patient records, and the tool has not been tested in everyday care yet.
The short version
Doctors built a scoring tool to help spot which lung cancer patients may be at higher risk of the cancer spreading to the brain.
What was studied. Researchers looked back at the records of 615 people with lung adenocarcinoma, a common type of lung cancer, at one hospital in China. 401 of them had cancer that had spread to the brain. 214 did not.
What they found. People whose tumors had a gene change called EGFR exon 19 deletion were more likely to have brain spread. Five markers in the blood were also higher in the people with brain spread. The team combined that gene change with the five blood markers into a scoring chart, and the chart sorted people into higher and lower risk fairly well.
What this means, and what it doesn't
What it could mean: Many people have no brain symptoms when they are first diagnosed. If this holds up in more studies, a doctor might one day use gene results and blood tests to decide who should get a brain scan sooner.
What it doesn't mean: This is not a treatment and it is not a cure. It does not lower anyone's chance of brain spread. The study just looked back at old records from a single hospital. The tool was only checked against that same group of patients. It has not been tested at other hospitals or put into everyday care. A high score would not mean a person has brain spread.
