The accumulated knowledge about the etiology, pathogenesis and morphology of gastritis has made it possible to coordinate the general ideas about gastritis in the classifications used by practicing physicians today, and the systems developed and implemented into practice for assessing atrophy/intestinal metaplasia (OLGA/OLGIM) undoubtedly can help the doctor in determining the tactics of curation of the patient.</p></abstract><trans-abstract xml:lang="ru"><p>Более века врачи отмечали связь хронического гастрита с развитием рака желудка, что побудило большой интерес к изучению и систематизации хронического гастрита, прежде всего для оценки индивидуального риска рака и эффективной канцеропревенции.
