This was tested in people. That is the most reliable kind of research we share.
This test was built from patient samples in one early study, and no one can get it yet.
The short version
Doctors looked for signs in blood and spinal fluid that show lung cancer has spread to the lining of the brain.
What was studied. Doctors took blood and spinal fluid from people with advanced lung cancer. Some had this spread to the brain lining and some did not. They tested 174 samples for many proteins.
What they found. There were 88 blood samples and 86 spinal fluid samples. Seven proteins in blood made one test, and 12 proteins in spinal fluid made a second test. The spinal fluid test gave the right answer more often than the blood test. In spinal fluid, 65 proteins were different between the two groups, and many were tied to swelling and the immune system.
What this means, and what it doesn't
What it could mean: A test like this could one day help find this kind of spread sooner. Finding it sooner could help you and your doctor plan care earlier. For now, this is only a first study.
What it doesn't mean: This does not mean a test is ready for you. The team built it from one group of patients and checked it against that same group. It has not been proven in new, larger groups of people. It is not a treatment, and it is not a cure.
