Fecal MicroRNA-Based Algorithm Increases Effectiveness of Fecal Immunochemical Test-based Screening for Colorectal Cancer.

An algorithm based on fecal levels of 2 microRNAs (miR-421 and miR-27a-3p), fecal hemoglobin concentration, and patient age and sex can identify patients with advanced colorectal neoplasia. We investigated whether this algorithm, called miRFec, could increase effectiveness and efficiency of fecal immunochemical test (FIT)-based colorectal cancer (CRC) screening programs.We obtained data and fecal samples from 767 persons with a positive result from the FIT who then underwent colonoscopy examination while participating a population-based CRC screening program, from March 2011 through May 2017 in Barcelona, Spain. Fecal miRNAs were isolated from the buffer contained in the original FIT collection device and analyzed by quantitative reverse transcription PCR. Aims were to evaluate the usefulness of the miRFec algorithm in identifying persons at greatest risk for CRC who should be prioritized for colonoscopy examination and individuals at low risk for whom colonoscopy could be avoided.Of the 767 study subjects, 414 (54.0%) were found by colonoscopy to have advanced colorectal neoplasia (67 with CRC and 347 with advanced adenomas) and 353 (46.0%) were found to have either non-advanced adenomas (n=136) or a normal examination (n=217). MiRFec algorithm scores (1-4) were independently associated with the presence of advanced colorectal neoplasia (P
