This was tested in people. That is the most reliable kind of research we share.
This looked back at past cases to help doctors name tumors, not to test a treatment.
The short version
Some brain tumors look like a tumor called oligodendroglioma but turn out to be something else.
What was studied. Doctors looked back at 23 tumors of the brain and spinal cord. Under the microscope, these tumors looked like oligodendroglioma, but they were not that type.
What they found. At first, doctors made many different guesses about what these tumors were. Extra tests of the tumors' proteins and genes gave the final answer. The most common final answer was a type of astrocytoma, found in 9 tumors, and 2 others were kidney cancer that had spread to the brain.
What this means, and what it doesn't
What it could mean: How a tumor looks under the microscope is not always enough to name it. Extra tests on the tumor can help doctors get the name right. You can ask your care team which tests were done on your tumor.
What it doesn't mean: This is not a new treatment, and it is not a cure. It only looked back at past cases to help doctors name tumors. It does not mean your own diagnosis is wrong.
