- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at what happened to real patients, but no new treatment was tested.
The short version
Some cancers that spread to the brain can also reach the area around the spinal cord, and many carry gene changes that some drugs can target.
What was studied. Doctors looked back at the records of 69 patients whose cancer had spread to the spinal cord or its lining. They studied when the cancer spread, where it came from, and its gene changes.
What they found. Most of these cancers started in the lung (33.3%) or the breast (31.9%). The cancer often reached the brain first and the spinal cord area later. In 46.4% of patients, the first tumor had gene changes that some drugs can target, and patients who got those drugs lived longer.
What this means, and what it doesn't
What it could mean: If you or a loved one has cancer that has spread, testing the tumor for gene changes may open up more treatment choices. The study authors think regular testing, such as testing spinal fluid, could help these patients.
What it doesn't mean: This study looked back at past records from one hospital. It did not test a new treatment. It does not show that targeted drugs work for everyone with this kind of spread. It is not a cure, and it does not change care on its own.
