Light probe could help surgeons spot brain tumors Mid-Operation
NCT ID NCT02473380
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tested a special light probe that helps surgeons see brain tumor tissue during an operation. Eleven adults with suspected brain tumors took part. The probe uses a drug that makes tumor cells glow, and the goal was to see if the device could accurately tell tumor from healthy brain tissue in real time.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- 5-aminolevulinic acid (Gliolan) as a contrast agent
- What this could lead to
- If successful, this could lead to a real-time tool that helps surgeons remove brain tumors more precisely during surgery.
- What could go wrong
- This is a very early feasibility study with only 11 people. The technique may not work as well in living patients as it did in the lab, and it is not yet ready for widespread use.
