Performance of the Fecal Immunochemical Test for Colorectal Cancer Screening Using Different Stool-Collection Devices: Preliminary Results from a Randomized Controlled Trial.

Background/aims: We are in the process of conducting a randomized trial to determine whether compliance with the fecal immunochemical test (FIT) for colorectal cancer screening differs according to the stool-collection method. This study was an interim analysis of the performance of two stool-collection devices (sampling bottle vs conventional container).

Methods: In total, 1,701 individuals (age range, 50 to 74 years) were randomized into the sampling bottle group (intervention arm) or the conventional container group (control arm).

The effect of changing stool collection processes on compliance in nationwide organized screening using a fecal occult blood test (FOBT) in Korea: study protocol for a randomized controlled trial.

Background: Colorectal cancer (CRC) screening by fecal occult blood test (FOBT) significantly reduces CRC mortality, and compliance rates directly influence the efficacy of this screening method. The aim of this study is to investigate whether stool collection strategies affect compliance with the FOBT.

Methods/design: In total, 3,596 study participants aged between 50 and 74 years will be recruited.
