NCT ID NCT06192719
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is collecting health data and biological samples from 15,000 people in Europe and Latin America to find markers that could predict gallbladder cancer risk or catch it early. Participants include patients with gallbladder cancer or gallstones. The goal is to improve prevention and diagnosis, since early surgery is currently the only cure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better ways to predict who is at risk for gallbladder cancer and detect it earlier, potentially saving lives through timely surgery.
- What could go wrong
- This is an observational study, not a treatment trial. It may take years to yield useful markers, and the findings might not apply to all populations.
This is an AI summary of the original study and may miss details. Read our disclaimer.
