This looks across many earlier studies rather than running a new one.
This looks back at how these tools worked in people, but the low-cost versions are not yet proven or widely used.
The short version
Doctors looked at cheaper ways to make tumors glow during surgery so surgeons can see them better.
What was studied. This review pulled together eight studies with 489 patients in lower-income countries or places with fewer resources. Surgeons used dyes that make tumor tissue glow during surgery, often with low-cost dyes and tools.
What they found. The glowing dyes helped surgeons find and remove tumors. Surgeons removed all of the visible tumor in 87% of patients, and one dye glowed in 96% of cases. The costs were much lower. One dye was over 100 times cheaper than a common brand-name dye, and a version made at the hospital was 14 times cheaper.
What this means, and what it doesn't
What it could mean: In the future, more hospitals with less money might be able to use this kind of surgery help. That could mean more patients around the world get it.
What it doesn't mean: This is a review of past studies, not a new test. The studies did not all measure the same things, so the results are hard to compare. Some of the cheaper tools are still early models. This is not a cure for brain tumors, and it does not change your own care today.
