BackgroundIn middle-income countries, the burden of colorectal cancer (CRC) is increasing in parallel with resources for diagnosis and treatment. There is a potential benefit of CRC screening programs in Mexico.ObjectiveSince there are no organized screening programs in the country, we explored the willingness of individuals to complete a faecal immunochemical testing (FIT) based CRC screening program and its potential benefit in Mexico.MethodsWe conducted a CRC screening program pilot in Veracruz, Mexico, during 2015-16 using FIT. Individuals with FIT results >100 ng of haemoglobin/ml buffer were referred for diagnostic colonoscopy.ResultsOf 473 FIT kits distributed to adults aged 50-75, 85.8% (406) were completed by participants and analysed in the laboratory. Of these, 5.9% (24/406) of test results showed >100 ng haemoglobin/ml. Twenty-one participants completed colonoscopy. The positive predictive value of FIT >100 ng haemoglobin/ml for premalignant lesions was 33%.ConclusionThese results provide preliminary evidence of the willingness of individuals to complete FIT-based CRC screening program in Mexico. However, further evaluation of health systems resources will be needed prior to large-scale implementation of CRC screening programs.© The Author(s) 2020. Published by Oxford University Press.
