The incidence of cardia gastric cancer (CGC) is rising worldwide, particularly in East Asia. There has been a debate over whether Helicobacter pylori ( H. pylori ) constitutes a risk factor for CGC. This study aimed to evaluate the relative risk of H. pylori infection and CGC in Asian countries.
Relevant studies examining H. pylori and CGC were searched in PubMed, Embase, and Web of Science from their inception to June 30, 2024. Either a random-effect model or a fixed-effect model was used to calculate pooled odds ratios (ORs) with 95% confidence intervals (CIs). Sensitivity analyses and assessments of publication bias were performed. The stability of results was evaluated in cases where publication bias was detected.
A total of 24 studies were included in the meta-analysis. A significant association between H. pylori and CGC was observed (OR = 2.20, 95% CI 1.73–2.80). In a subgroup analysis of different countries, a significant association was observed in East Asian countries, including China (OR = 2.12, 95% CI 1.63–2.77), Japan (OR = 2.21, 95% CI 1.16–4.20), and Korea (OR = 2.36, 95% CI 1.58–3.54), but not in Iran (OR = 1.48, 95% CI 0.77–2.84). The pooled OR from five prospective cohort studies revealed a strong association between H. pylori and CGC (OR = 2.32, 95% CI 1.47–3.66).
East Asia bears a significant burden of H. pylori -related CGC. A clear association between H. pylori infection and CGC was observed in this region.

The study was recently published in the Cancer Screening and Prevention .
Cancer Screening and Prevention (CSP) publishes high-quality research and review articles related to cancer screening and prevention. It aims to provide a platform for studies that develop innovative and creative strategies and precise models for screening, early detection, and prevention of various cancers. Studies on the integration of precision cancer prevention multiomics where cancer screening, early detection and prevention regimens can precisely reflect the risk of cancer from dissected genomic and environmental parameters are particularly welcome.
