- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at real patients they had already operated on, but this has not been tested in a proper trial.
The short version
Surgeons used a scan of the tumor's chemistry to find its edge, and those patients lived longer.
What was studied. Doctors at one hospital looked back at records of people 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 who had surgery. 41 people had surgery guided by a special scan called 3D MR spectroscopy, which maps the tumor's chemistry. 30 people had the usual surgery, guided by a standard scan that shows the tumor's bright edge.
What they found. In the special scan group, 25 of the 41 people had the tumor removed plus a margin of tissue around it. In the usual surgery group, 10 of the 30 people did. Nerve problems after surgery were uncommon in both groups. 1 person in the special scan group had a problem, and it went away. 2 people in the usual surgery group had one, and for 1 of them it was permanent. People in the special scan group went longer before the tumor grew again, and they lived longer overall.
What this means, and what it doesn't
What it could mean: How a surgeon decides where the tumor ends may matter for how much gets removed and how long people live. If you or someone you love is facing glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary surgery, you could ask the surgical team what scans they use to plan the operation and whether this kind of scan is available where you are. It is not offered everywhere.
What it doesn't mean: This is not a cure, and it is not a new drug. The doctors looked back at patients they had already treated at one hospital. They did not run a trial where people were randomly assigned to one kind of surgery or the other. That means other differences between the two groups could explain part of the result. The number of people was small. This approach needs to be tested in larger, better designed studies before anyone can say it should be standard care.
