Norway launches massive colorectal cancer screening showdown: which test saves more lives?
NCT ID NCT01538550
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This large pilot study in Norway is comparing two common colorectal cancer screening methods—flexible sigmoidoscopy (a one-time scope exam) and biennial fecal immunochemical testing (a stool test)—to see which works best for the general population. Over 140,000 men and women aged 50-74 are taking part. The goal is to find the most effective way to reduce colorectal cancer deaths and improve screening services nationwide.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
flexible sigmoidoscopy and fecal immunochemical test (iFOBT)
What this could lead to
If successful, this could help determine the most effective screening strategy for colorectal cancer, potentially reducing deaths from the disease on a national level.
What could go wrong
This is a pilot study comparing screening methods, not testing a new treatment. Results may not apply to other populations, and screening itself carries risks like false positives or complications from follow-up procedures.
