Core tip: The effectiveness of new gastric cancer screening technique has remained limited to date. The present review of 3 new gastric cancer screening techniques, namely, upper gastrointestinal endoscopy, serological testing, and “screen and treat” method provides invaluable insights on how screening tests should be instituted. To effectively introduce new techniques for gastric cancer screening in a community, incidence and mortality reduction from gastric cancer must be initially and thoroughly evaluated by conducting reliable studies. In addition to effectiveness evaluation, the balance of benefits and harms must be assessed before introducing these new techniques for population-based screening.
