PG - 1699-1708 LID - 10.1007/s00228-023-03580-7 [doi] AB - PURPOSE: To elucidate whether long-term proton pump inhibitor (PPI) users have an increased gastric cancer (GC) risk. METHODS: We searched the 2009-2019 Korean National Health Insurance Services Database for patients aged > 40 years who claimed for Helicobacter pylori eradication (HPE) during 2009-2014. The GC incidence following a PPI exposure of > 180 cumulative defined daily dose (cDDD) and that following an exposure of < 180 cDDD were compared. The outcome was GC development at least 1 year following HPE. A propensity score (PS)-matched dataset was used for analysis within the same quartiles of the follow-up duration. Additionally, dose-response associations were assessed, and the mortality rates were compared between long-term PPI users and non-users. RESULTS: After PS matching, 144,091 pairs of PPI users and non-users were analyzed. During a median follow-up of 8.3 (interquartile range, 6.8-9.6) years, 1053 and 948 GC cases in PPI users and non-users, respectively, were identified, with the GC incidence (95% confidence interval (CI)) being 0.90 (0.85-0.96) and 0.81 (0.76-0.86) per 1000 person-years, respectively. The adjusted hazard ratio (aHR) for GC with PPI use was 1.15 (95% CI, 1.06-1.25). Among PPI users, patients in the highest tertile for annual PPI dose showed higher GC development than those in the lowest tertile (aHR (95% CI): 3.87 (3.25-4.60)). GC-related mortality did not differ significantly between PPI users and non-users. CONCLUSION: In this nationwide analysis in Korea, where the GC prevalence is high, long-term PPI use after HPE showed a significant increase in GC, with a positive dose-response relationship.
