- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was watched in people having real surgery, but it still needs more study.
The short version
Surgeons removed the tumor and nearby tissue as one block, and those patients lived longer.
What was studied. Doctors looked at people with glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary in brain areas that do not control key functions. They compared a surgery that takes out the tumor and the tissue next to it as one whole block.
What they found. People who had this surgery lived longer, and their cancer took longer to grow back. The tissue next to the tumor looked normal under a microscope, but it carried tumor-like changes. Those changes were mostly in tissue within 10 mm of the tumor.
What this means, and what it doesn't
What it could mean: Removing a bit more tissue around the tumor may help some people live longer. It may be worth asking your surgeon how much tissue they plan to take out and why.
What it doesn't mean: This is not a cure, and it is not proof for every person. The study only covered tumors in brain areas that do not control key functions. The authors say more study is needed before this changes everyday surgery. Your own care depends on where your tumor sits.
