This was tested in people. That is the most reliable kind of research we share.
This is a report of what happened to three patients, not a treatment being tested.
The short version
glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary almost always stays in the brain, but in rare cases it can spread to other parts of the body.
What was studied. Doctors looked back at the records of 3 patients treated at their hospital who had glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary that spread outside the brain and spine. They reviewed scans, lab tests, and tissue samples. A tissue test confirmed the spread in 2 of three patients.
What they found. Reports say this kind of spread happens in fewer than 2% of cases. In one man, age 55, the tumor spread to a lymph node in his neck within 6 months of his first surgery. In another man, age 56, it spread to bone, lung, liver, and the wall inside the heart about 18 months after diagnosis. A woman, age 48, lived 61 months and had late spread to several organs. The three patients lived 8, 22, and 61 months.
What this means, and what it doesn't
What it could mean: It helps to know that this can happen, even though it is rare. If you have lived a long time with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary, or you have new symptoms in other parts of your body, tell your care team. The authors say doctors should think about this possibility. A whole body scan and a tissue sample can show if it is really the tumor.
What it doesn't mean: This is not a new treatment, and it is not a cure. It is a report on 3 patients at one hospital. Reports like this cannot prove why the spread happened or what to do about it. It does not mean spread outside the brain is common. It also does not mean your care will change today.
