Pilot study pits cologuard against FIT for colon cancer screening in younger adults
NCT ID NCT06173375
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study compared two stool-based tests—Cologuard and the fecal immunochemical test (FIT)—for colorectal cancer screening in adults aged 45-49. Researchers mailed the tests to eligible participants and tracked how many completed screening, had abnormal results, and followed up with a colonoscopy. The study involved only 12 people and aimed to see which test works better for this age group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Cologuard (multi-target stool DNA test) and Fecal Immunochemical Test (FIT)
- What this could lead to
- If successful, this could help determine which stool-based screening method is more effective for colorectal cancer detection in younger adults.
- What could go wrong
- This is a very small pilot study with only 12 participants, so results may not apply to larger populations. It does not test new treatments or cures.
