High-risk polyps at screening colonoscopy are associated with upper gastrointestinal cancer mortality

Aims Currently, gastric cancer screening is only cost-effective in countries with high incidence. Colorectal cancer screening is an effective method for the reduction of CRC incidence and receives high attendance rates. Integrated screening, where gastroscopy is performed in conjunction with colonoscopy, could help reduce the gastric cancer screening procedure burden in countries with low or intermediate incidence. However, there is a lack of population-based studies providing data on groups at high risk for mortality from gastric malignancies that might benefit from this approach.
