This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at people who were already treated, so this shows a link and not proof.
The short version
Patients lived longer when surgeons used several special tools, but only when the tumor sat in a brain area that controls things like speech or movement.
What was studied. Doctors looked back at the records of 81 patients with a WHO grade 4 glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary in the upper part of the brain. They checked how many surgery support tools were used, such as awake surgery, brain mapping during the operation, and dye that makes tumor tissue glow.
What they found. No tools were used in 30 patients. One tool was used in 20 patients, two in 15, three in 9, and four in 7. For tumors in brain areas that control speech or movement, typical survival was 194 days with no tools, 364 days with one or two tools, and 674 days with three or four tools. For tumors in other brain areas, the number of tools made no difference.
What this means, and what it doesn't
What it could mean: If your tumor is near a part of the brain that controls speech or movement, it may be worth asking your surgical team which of these tools they use.
What it doesn't mean: This does not mean these tools cure a brain tumor. The doctors looked back at past records at one center. They did not run a planned trial. A study like this can show a link, but it cannot prove the tools are the reason people lived longer. Patients who were sicker may have been given fewer tools to begin with. These tools are already used in some hospitals, but this is not a promise about how long anyone will live.
