A validated claims-based algorithm successfully identifies incident gastric cancer cases and determines progression phases in Japan. It demonstrated a positive predictive value of up to 95.9% and sensitivity rates reaching 98.9% in validation cohorts. This advancement enables better analysis of real-world gastric cancer scenarios, facilitating improved decision-making in treatment options. By addressing issues associated with the uncertainty of disease names, this algorithm holds promise for enhancing gastric cancer research outcomes.
