What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This study looks at genetic and molecular markers in tissue and stool samples from people with colon cancer, colon polyps, and healthy controls. Researchers aim to understand how these markers differ and how they relate to cancer development. The study involves 582 participants and uses advanced techniques to analyze DNA, proteins, and gut bacteria.

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 help identify which markers signal early cancer risk, potentially improving screening or prevention strategies.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to direct patient benefits, and findings may not apply to all populations.
