This was done on cells in a lab, not in people. It is a very early step.
This was only done on tissue samples in a lab, not during real surgery.
The short version
Researchers tested a quick way to spot glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary tissue during surgery, but it is still early lab work.
What was studied. Scientists studied 86 human brain samples in a lab. They used a tool that measures tiny chemicals in tissue, then compared pairs of those chemicals as ratios.
What they found. Several ratios told tumor tissue apart from tissue that was not tumor. Some ratios also sorted gliomas by grade and by whether the tumor had an IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary. A few ratios matched the lab's own clinical results with 100% agreement. One chemical, carnitine, was higher in all glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary types.
What this means, and what it doesn't
What it could mean: If this works in the operating room, it could one day help a surgeon see where a tumor ends. That might help them know how much to remove. For now it changes nothing about your care.
What it doesn't mean: This does not mean a new treatment. It is not a cure, and it does not treat a tumor at all. The work was done on tissue samples in a lab, not during real surgery. It has not been tested in the operating room. Years of more testing would be needed before a hospital could use it.
