Glow-in-the-Dark dye helps surgeons find colon cancer
NCT ID NCT07380867
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial tests a dye mixture called Luminomark, which is injected into the colon wall near a tumor during a colonoscopy. The dye glows under a special camera during surgery, helping surgeons see exactly where to cut. The study involves 30 adults with early-stage colorectal cancer who need surgery. The goal is to see if this marking method improves surgical accuracy and reduces unnecessary tissue removal.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Indocyanine Green (ICG) and Hyaluronic Acid mixture (Luminomark)
- What this could lead to
- If successful, this marking method could help surgeons locate colon tumors more accurately during surgery, reducing the need for extra tissue removal.
- What could go wrong
- This is a small, early-stage study with only 30 participants. The dye may not always be visible or could cause minor side effects like fever or allergic reactions.
