Dye test could catch hidden cancer in achalasia patients
NCT ID NCT02010983
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
People with achalasia, a swallowing disorder, have a much higher risk of developing esophageal cancer. This study tested whether spraying a special dye (Lugol) during an endoscopy could help doctors find early signs of cancer (dysplasia) in 39 patients who had achalasia for over 15 years. The goal was to see if this screening method works better than standard endoscopy alone.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- chromoendoscopy with Lugol dye
- What this could lead to
- If successful, this screening method could help catch esophageal cancer earlier in people with achalasia, potentially improving survival.
- What could go wrong
- This is a small, completed observational study, not a treatment trial. The dye technique may not be widely adopted or may not reduce cancer deaths.
