This looks across many earlier studies rather than running a new one.
This is a report on one patient plus a review of past cases, not a new treatment.
The short version
In one man, a growth on the covering of his brain turned out to be prostate cancer that had spread.
What was studied. Doctors reported one case. A 63-year-old man who had been treated for prostate cancer had headaches, weight loss, and growing confusion for three months. They also searched medical databases and found 19 studies with 44 patients who had the same rare problem.
What they found. Brain scans showed a large growth on the outside of his brain, on the right side. It looked like a common tumor of the brain lining called a meningioma. Surgeons removed it, and lab tests showed it was prostate cancer that had spread to the brain lining. After surgery he had serious problems, including bleeding in the brain and high pressure inside his head.
What this means, and what it doesn't
What it could mean: If you have had prostate cancer, a new growth on the brain lining may not be what it first looks like. Doctors may need to test the tissue to know for sure. Knowing this can help a care team pick the right next step.
What it doesn't mean: This is not a test of a new treatment, and it is not a cure. It is one patient's story plus a review of past reports. Reports like these are the earliest kind of evidence. The authors say the evidence is limited, and larger studies are needed. Nothing here changes everyday care today.
