This was tested in people. That is the most reliable kind of research we share.
This is one patient's case report, not a new treatment or a trial.
The short version
Doctors describe one patient whose glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary spread fast to the layers that cover the brain, soon after surgery and standard treatment.
What was studied. This is a report about one patient 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, IDH-wildtype, CNS WHO grade 4. Doctors looked at the patient's scans, tumor tissue, and lab tests on the tumor.
What they found. The patient had as much tumor removed as was safe, then had the standard treatment of radiation with chemotherapy. Within three months, the tumor spread to the coverings of the brain in more than one spot. Scans showed thickening of the tough outer covering, away from where the tumor started. Lab tests showed a giant cell tumor type whose cells were dividing very fast.
What this means, and what it doesn't
What it could mean: Some glioblastomas can spread to the coverings of the brain sooner than most doctors expect. The authors suggest that detailed testing of the tumor and scans of the brain and spine can help spot this kind of spread. If you have glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary, it is fair to ask your care team what your scan plan is and what your tumor's lab tests showed.
What it doesn't mean: This is a report about one patient, not a study of a group. It does not test any new treatment, and nothing here is a cure. It does not mean this spread is common or that it will happen to you. The authors say plainly that there is not enough evidence yet to change how surgery or care around surgery is done.
