This was tested in people. That is the most reliable kind of research we share.
This is one patient's story, not a trial that shows the drug works for others.
The short version
Doctors share one man's treatment story, not proof that a drug works for others.
What was studied. This is a report about one patient, not a study of a group. A 65-year-old man had lung cancer that had spread to his lungs, lymph nodes, and bones. Tests found extra copies of a gene called MET and high levels of a protein called PD-L1.
What they found. Chemotherapy and an immune drug each helped for a while, but the cancer kept spreading. A MET drug called capmatinib later shrank the cancer a lot, after radiation to his brain. He died about 30 months after diagnosis, from liver failure and infection.
What this means, and what it doesn't
What it could mean: His doctors tried a MET drug even though he lacked the gene change it is normally used for. It helped him for a time. What fits your care depends on your own test results. Ask your team what your tests show.
What it doesn't mean: This is one person's story, not a trial. One case cannot show that a drug works for other people. It does not mean this drug treats brain tumors or fits most lung cancers. The drug was not a cure. He still died of his illness. Doctors say this idea needs real trials before it becomes normal care.
