Multicenter Study Observational StudyDiagnostic accuracy of a quantitative faecal immunochemical test vs. symptoms suspected for colorectal cancer in patients referred for colonoscopy.
Objective: Determine diagnostic accuracy of a quantitative faecal immunochemical haemoglobin test (QuikRead go® FIT, Orion Diagnostica Oy) in symptomatic patients referred for colonoscopy, at various cut-offs and for one or two tests. Methods: Patients referred to four endoscopy units in mid-Sweden between 2013 and 2017 provided information on lower abdominal symptoms and faecal samples from two separate days prior to colonoscopy. Results: In all, 5.4% (13/242) patients had colorectal cancer (CRC). ⋯ Conclusion: One or two FITs in symptomatic patients referred for colonoscopy imply powerful risk stratification abilities for CRC, even among patients reporting rectal bleeding. Larger studies in various settings will clarify how to make the best use of this opportunity. Trial registration: Clinicaltrails.gov NCT02491593.
