Purpose of review The gastritis constellation includes heterogeneous clinicopathological entities, among which long-standing, non-self-limiting gastritis, mainly due to Helicobacter pylori infection, has been epidemiologically, biologically, and clinically linked to gastric cancer development (i.e. "inflammation-associated cancer"). This review illustrates the updated criteria applied in the taxonomy of gastritis (Kyoto classification), elucidates the biological rationale for endoscopy biopsy

Recent findings By assuming gastric atrophy as the "cancerization field" where (nonsyndromic) gastric cancer mostly develops, recent long-term follow-up studies consistently demonstrate the prognostic impact of the gastritis OLGA staging system. Summary Helicobacter pylori eradication is the leading strategy in the primary prevention of gastric cancer. In a multidisciplinary dimension of secondary cancer prevention, the OLGA staging system reliably ranks the patient-specific cancer risk, thus providing the clinical rationale for a tailored follow-up strategy.
