Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting

Summary

This study looks at whether analyzing the bacteria in stool samples with artificial intelligence can better predict colorectal cancer risk than the standard stool test. Researchers will collect samples from 2,500 people aged 50-75 who are already scheduled for a colonoscopy. The goal is to see if this new method can more accurately identify who truly needs a colonoscopy, potentially reducing unnecessary procedures.

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 a more accurate, non-invasive screening test for colorectal cancer, reducing unnecessary colonoscopies.
What could go wrong
This is an observational study, not a treatment trial. The new test may not prove more accurate than current methods, and results may not apply to all populations.
