Which test is best for colon cancer screening in High-Risk families?
NCT ID NCT02738359
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at three screening methods—colonoscopy, colon capsule endoscopy, and a fecal immunochemical test (FIT)—to detect colorectal cancer or advanced growths in people aged 45 and older who have a first-degree relative with colorectal cancer. The goal was to see if the simpler tests (capsule or FIT) are as good as colonoscopy. The study enrolled 84 participants and compared how many cancers or advanced polyps each method found.
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 show that simpler, less invasive tests like colon capsule or fecal tests are as effective as colonoscopy for screening high-risk relatives.
- What could go wrong
- This is a small, completed study with only 84 participants, so results may not apply to larger populations. The non-inferiority margin is narrow, and differences between tests may still be uncertain.
