NCT ID NCT07635745
First seen Jun 10, 2026 · Last updated Jun 23, 2026 · Updated 1 time
Summary
This study looked at 120 South American patients with gallstones to confirm if certain bacteria in stool are linked to gallbladder cancer risk. Researchers measured three types of gut bacteria using advanced DNA sequencing. The goal was to validate earlier findings that these bacteria may signal higher cancer risk. No treatment was given; this was an observational study to better understand the connection.
