Summary

This study is testing whether a green dye called indocyanine green (ICG) can help surgeons see and remove lymph nodes that contain cancer during laparoscopic colon cancer surgery. About 25 adults with colon cancer will receive the dye injected around the tumor and into a vein. The goal is to see if all cancerous lymph nodes are found within the dyed area. This is a small, early-stage study to check if the technique works, not a treatment itself.

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) dye
What this could lead to: If successful, this technique could help surgeons remove all cancerous lymph nodes during colon cancer surgery, potentially reducing the chance of cancer returning.
What could go wrong: This is a small, early pilot study with only 25 people, so results may not apply to everyone. The dye may not always highlight all cancerous nodes, and there is a small risk of allergic reaction.
