Table 1_Stratified management of residual gastric cancer risk after Helicobacter pylori eradication.xlsx

Despite the established efficacy of Helicobacter pylori eradication in reducing gastric cancer (GC) incidence, a significant residual risk persists in successfully treated individuals, driven by lasting pathological alterations termed “oncogenic memory,” including irreversible mucosal damage (e.g., intestinal metaplasia), residual pro-inflammatory and epigenetic “molecular scars,” and gastric microbiome dysbiosis. This perspective synthesizes current evidence to advocate for a paradigm shift from a singular focus on pathogen clearance towards a comprehensive, risk-adapted management strategy. We propose a novel, dual-dimensional framework centered on a multidimensional risk assessment that integrates OLGA/OLGIM staging, demographic, lifestyle, and genetic factors to stratify post-eradication individuals into distinct risk categories. The framework subsequently outlines tailored surveillance protocols—specifying endoscopy frequency and advanced biomarker application—leverages technological support from AI-assisted endoscopy and molecular testing, and details differentiated resource allocation models based on regional GC incidence and economic development. This integrated approach provides a practical roadmap for implementing precision prevention, aiming to mitigate the lingering GC risk and ultimately reduce the global disease burden through a dynamic, lifelong management system beyond eradication. To facilitate implementation, we provide a user-ready risk calculator that operationalizes the multidimensional score for cohort-level application.
