Материалы и методы. В исследование было включено 26 случаев хронического атрофического гастрита 3 и 4 стадий с высоким риском развития РЖ согласно оценке с помощью системы OLGA (операционная система оценки гастрита). Случаи были диагностированы на текущем диагностическом материале гастробиоптатов в 2022 году. Всего за год было выполнено 678 гистологических исследований. Случаи хронического гастрита с высоким риском развития РЖ составили 3,8% от всех хронических гастритов. Результаты. Случаи хронического гастрита с высоким риском развития РЖ чаще наблюдались у пожилых мужчин (средний возраст 67±12 лет, соотношение 2,25:1). На первом месте по частоте встречаемости оказался мультифокальный атрофический гастрит (61,5%), связь с хеликобакетрной инфекцией подтверждена только в трети случаев (34,6%). Морфологические изменения характеризовались преимущественным поражением антрального отдела желудка и смешанной полной и неполной кишечной метаплазией. За исключением одного случая, в котором была обнаружена псевдопанкреатическая метаплазия в антральном отделе желудка, все случаи аутоиммунного гастрита (n=26) были отнесены ко 2 стадии с низким риском развития РЖ, что нам кажется спорным. Заключение. Результаты нашего исследования показали высокий процент уже существующих опухолевых поражений желудка в группе хронических гастритов с высоким риском развития РЖ. Дисплазия была диагностирована в 5 из 26 наблюдений, РЖ с выполненной ранее мукозэктомией в 3 из 26 случаев. Помимо этого, пациенты имели другие опухолевые и предопухолевые поражения ЖКТ. Эти данные показывают обоснованность и практическую ценность использования системы OLGA для выделения групп высокого риска развития опухолей не только желудка, но и опухолей ЖКТ других локализаций.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of this study is to conduct a clinical and morphological analysis of cases of chronic gastritis with a high risk of gastric cancer (GC). Materials and methods. The study included 26 cases of chronic atrophic gastritis of stages 3 and 4 with a high risk of developing GC according to the assessment using the OLGA system (Operative Link for Gastritis Assessment). The cases were diagnosed on material of gastric tissue biopsy in 2022. In total, 678 histological studies were performed during the year. Cases of chronic gastritis with a high risk of developing GC accounted for 3.8% of all chronic gastritis. Results. Cases of chronic gastritis with a high risk of developing GC were more often observed in older men (average age 67±12 years, ratio 2.25:1). Multifocal atrophic gastritis was in the first place in frequency of occurrence (61.5%), the connection with helicobacter infection was confirmed only in a third of cases (34.6%). Morphological changes were characterized by a predominant lesion of the antrum of the stomach and mixed complete and incomplete intestinal metaplasia. With the exception of one case in which pseudopancreatic metaplasia was detected in the antrum of the stomach, all cases of autoimmune gastritis (n=26) were assigned to stage 2 with a low risk of developing GC, which seems controversial to us. Conclusion. The results of our study showed a high percentage of pre-existing tumor lesions of the stomach in the group of chronic gastritis with a high risk of developing GC. Dysplasia was diagnosed in 5 out of 26 cases, GC with previously performed mucosectomy in 3 out of 26 cases. In addition, the patients had other tumor and precancerous lesions of the gastrointestinal tract. These data show the validity and practical value of using the OLGA system to identify high-risk groups for the development of tumors not only of the stomach, but also of gastrointestinal tumors of other localizations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Хронический гастрит</kwd><kwd>рак желудка</kwd><kwd>OLGA/OLGIM</kwd><kwd>морфологическая диагностика</kwd><kwd>атрофия</kwd><kwd>метаплазия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Chronic gastritis</kwd><kwd>gastric cancer</kwd><kwd>OLGA/OLGIM</kwd><kwd>morphological diagnosis</kwd><kwd>atrophy</kwd><kwd>metaplasia</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rugge M., Correa P., Di Mario F., et al.
