Атрофический гастрит (АГ) - основное предраковое состояние рака желудка (РЖ), в диагностике и скрининге которого широко используют неинвазивные биомаркеры (пепсиногены, гастрин-17), однако сведения о них при РЖ противоречивы. Цель исследования. В «серии случаев» оценить показатели биомаркеров желудочной атрофии и некоторые факторы риска развития РЖ разной локализации, морфологии и стадии. Материал и методы. В исследование дизайна «серия случаев» включены 85 пациентов с РЖ (48 мужчин и 37 женщин, средний возраст 61,2±13,6 года), последовательно обращавшихся в два лечебных учреждения. Проведено анкетирование всех больных с включением вопросов о курении и потреблении алкоголя, наличии гастроинтестинальных симптомов и наследственности. Образцы сыворотки крови тестировали с помощью набора диагностикумов для иммуноферментного анализа «ГастроПанель» («Biohit Plc», Финляндия). В оценке биомаркеров АГ использовали пороговые значения, рекомендуемые производителем. Результаты. Диагноз РЖ у 67,9% больных установлен на III и IV стадиях заболевания. Опухолевой процесс у большинства больных (у 63,5%) локализовался в теле желудка. Инфекция Helicobacter pylori (H. pylori) выявлена при серологическом исследовании у 74,1% больных, у 15,1% которых была предпринята попытка провести эрадикационную терапию. У 90,6% больных выявлена аденокарцинома с разной степенью дифференцировки, преимущественно (у 57,6%) низкой. Перстневидно-клеточный рак диагностирован у 7,1% больных, недифференцированная опухоль - у 2,4%. Уровень пепсиногена I (ПГI) ниже 50 мкг/л, свидетельствующий о фундальной атрофии разной степени выраженности, установлен у 43,2% больных. Достоверно низкие показатели ПГI определены у пациентов с РЖ и морфологически подтверждённой атрофией. Различий в уровнях биомаркеров в зависимости от локализации опухолевого процесса, морфологического варианта РЖ и стадии заболевания не выявлено. Выводы. В исследовании «серия случаев» установлены высокая частота поздней диагностики РЖ с преобладанием его корпусной локализации и наиболее злокачественных форм. Инфекция H. рylori серологически выявлена у большинства пациентов, но попытки провестия эрадикационную терапию были предприняты только у 15%. Фундальная атрофия серологически диагностирована более чем у 40% больных, но связь ее развития с локализацией, стадией и морфологическим вариантом опухоли не установлена.</p></abstract><trans-abstract xml:lang="en"><p>Background. Atrophic gastritis (AG), being the basic premalignant condition for the stomach cancer (SC), is commonly diagnosed and screened for by noninvasive biomarkers (pepsinogens, gastrin-17), however the data on those biomarkers at SC is inconsistent. Aim of investigation. To evaluate the markers of stomach atrophy along with risk factors of SC of different localization, histological type and stage in the «case series» study. Material and methods. Original investigation was designed as «case series», that included 85 patients with SC (48 m and 37 f, mean age 61.2±13,6 years) who were consistently referred to two medical institutions. All patients underwent interviewing the questionnaire concerning smoking and alcohol consumption, presence of gastroenterological symptoms and family history. Blood serum samples were analyzed using ELISA test kits «GastroPanel» («Biohit Plc», Finland). Manufacturer recommended threshold levels were used at diagnostics of AG. Results. The diagnosis of SC of the III to IV stage was established in 67.9% of patients. The most common location of the neoplasm was the stomach body (63,5%). Helicobacter pylori (H. pylori) infection was revealed by serological method in 74.1% of cases, of which in 15.1% the attempt of eradication treatment was carried out. In 90.6% of patients the adenocarcinoma of different differentiation grade was diagnosed, low degree of differentiation was the most common (57.6%). Signet-ring cell carcinoma was diagnosed in 7.1% of patients, undifferentiated tumor - in 2.4%. Pepsinogen-I (PGI) level under 50 mcg/l was found in 43.2% of patients, indicating different degrees of fundic atrophy. Significantly lower PGI scores were detected in SC patients with histologically verified atrophy. No significant differences in biomarker levels according to tumor location, histological type of SC and tumor stage were found. Conclusions. The «case series» study demonstrated high rate of late SC diagnostics with predominance of corpus location and the most malignant types. H. pylori infection was diagnosed in serologically in the most of patients, however attempts for eradication therapy was carried out only in 15% of patients. Fundic atrophy was diagnosed by serological tests in over 40% of patients, however no association with location, stage and morphological type of the tumor was established. Blood serum samples were analyzed using ELISA test kits «GastroPanel» («Biohit Plc», Finland). Manufacturer recommended threshold levels were used at diagnostics of AG.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>атрофический гастрит</kwd><kwd>неинвазивная диагностика</kwd><kwd>пепсиногены</kwd><kwd>Helicobacter pylori</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">Schistosomes, liver flukes and Helicobacter pylori.
