Alsayid M, et al. - Authors sought to examine the ability of fecal immunochemical test (FIT) for the purpose of colorectal cancer (CRC) screening in patients (50–75 years old) in the San Francisco Health Network using OC-Light FIT from August 2010 through June 2015. It was observed that a positive result from the FIT detected patients with CRC with a positive predictive value of 3.0%, and patients with advanced adenoma with a positive predictive value of 20.8%. Higher FIT positive rate was illustrated during the first round of testing (9.4%) compared to subsequent rounds.
