Background: Endoscopic screening for gastric cancer is debatable in countries with an intermediate risk. Objective: The objective of this article is to determine the cost-utility of screening strategies for gastric cancer in a European country. Methods: We conducted a cost-utility analysis using a Markov model comparing three screening strategies versus no screening: stand-alone upper endoscopy, endoscopy combined with a colorectal cancer screening colonoscopy after a positive faecal occult blood test or pepsinogens serologic screening. Clinical data were collected from systematic reviews, costs from published national data and utilities as quality-adjusted life years (QALY). The primary outcome was the incremental cost-effectiveness ratio (ICER). Deterministic and probabilistic sensitivity analyses were performed. The threshold was set at (sic)37,000 (2016 prices). Results: Upper endoscopy combined with screening colonoscopy (every 10 or 5 years) had an ICER of 15,407/QALY and (sic)30,908/QALY respectively, stand-alone endoscopic screening (every five years) an ICER of (sic)70,693/QALY and pepsinogens screening an ICER of (sic)143,344/QALY. Sensitivity analyses revealed that only endoscopic costs <(sic)75, a provision of only three endoscopies per patient or a gastric cancer risk >25/100,000 would make stand-alone endoscopic screening cost-effective. Conclusion: Endoscopic gastric cancer screening in Europe can be cost-effective if combined with a screening colonoscopy in countries with a gastric cancer risk 10 per 100,000.
