Colorectal cancer (CRC) is the leading cancer incidence and mortality worldwide and Vietnam. While screening is considered an effective measure to prevent and control of CRC in the world, there has no such effort in Vietnam. Between January 01, 2018 and October 31, 2019, a population-based CRC screening program was conducted in Hanoi, Vietnam. A health advocacy campaign and followup phone calls were used to invite residents aged 40 years old or older. Immunochemical-fecal occult blood testing (iFOBT) was used as the primary screening method, followed by a colonoscopy among those who had iFOBT positive test results. During almost 2 years, 80,330 individuals among a total of 672,742 eligible residents attended the screening finished iFOBT test and the positive rate was 6.1%. The total attendance rate of iFOBT screening was 11.9%. Among 2,287 individuals who underwent colonoscopy, 3.5% were histologically diagnosed with cancer, 17.8% with advanced adenomas and 23.1% with non-advanced adenomas. Male had significant higher proportions advanced-adenomas and cancer and had >5 polyps/tumor than female. We showed that two-step of modality (i.e., iFOBT test and colonoscopy) an efficient and promising strategy for CRC screening in Vietnam that might be applied in community screening
