This was tested in people. That is the most reliable kind of research we share.
This looked back at past surgeries in children, not a planned trial.
The short version
Surgeons used a glowing yellow dye to see tumor tissue better during brain surgery in children.
What was studied. Doctors looked back at 60 brain tumor surgeries in 50 children, done between 2015 and 2023. In 32 of those surgeries the team used a dye called sodium fluorescein, and in 28 they did not.
What they found. The whole tumor was removed in 93.8% of the dye surgeries. Without the dye, the whole tumor was removed in 71.4%. Surgeries with the dye also took less time, and no child had a bad reaction to the dye.
What this means, and what it doesn't
What it could mean: This dye may help a surgeon see tumor edges more clearly in children. At the low dose used here, it looked safe. If your child needs brain surgery, you can ask the surgeon whether they use this dye.
What it doesn't mean: This does not mean the dye is proven to work. The team looked back at past records instead of running a planned trial, and the two groups of children were not well matched. The tumors were also different from each other. The authors say new studies are needed. Taking out more tumor is not a cure, and this study does not show whether children lived longer.
