This was tested in people. That is the most reliable kind of research we share.
This is a report about one patient being watched, not a new treatment.
The short version
One woman had a small pocket of blood near her brain while her cancer was shrinking, and it healed on its own.
What was studied. Doctors wrote up one patient. She was a woman in her 30s with lung cancer that had spread to the lining of the brain. She was treated with a drug called lorlatinib, which can reach the brain.
What they found. After 7 weeks on the drug, a scan showed a pocket of blood outside her brain. It caused no symptoms, and the cancer spots in the brain lining were shrinking at the same time. She stayed on the drug with close care from her team, and the blood pocket went away without surgery. It did not come back during 6 years of treatment.
What this means, and what it doesn't
What it could mean: This is a heads up that a pocket of blood can show up during this kind of treatment. It may cause no symptoms and may only be seen on a scan. In this one case, the team kept the drug going, watched closely, and the problem cleared up by itself. Ask your own team what your scans show.
What it doesn't mean: This is one person's story, not a study. One case cannot tell us how often this happens, or what is right for anyone else. It is not a cure, and it does not change the rules doctors follow for care. Never stop or change a drug on your own.
