However, there are still no clear criteria for the assessment of clinically significant abnormalities of the main NET biomarkers chromogranin A (CgA) and serotonin. <bold>Aim</bold>: To evaluate the value of serial measurement of serum CgA and serotonin in the monitoring of the treatment effect in NET patients. <bold>Materials and methods</bold>: Serum CgA and serotonin levels were measured in 107 patients with NETs at baseline and at 3–4 weeks after the end of treatment (chemotherapy, biotherapy), as well as in 60 healthy controls. We used enzyme immunoassay based on Chromogranin A NEOLISA (Euro Diagnostica) and Serotonin ELISA (IBL International GmbH) test systems. <bold>Results</bold>: There was an association between CgA levels and the efficacy of chemotherapy in NET patients. With progression of the disease, median CgA increased significantly from 412 to 2679 ng/mL (p = 0.012), whereas in the patients with partial response it decreased from 811 to 254 ng/mL (p = 0.023). The ROC analysis showed the 33% cut-off for significant CgA changes for progression, with sensitivity of 80.0% and specificity of 95.6%. A decrease (of more than 33% compared to baseline levels) or absence of significant CgA changes was associated with stabilization of the disease or with partial response to treatment. Significantly decreased CgA levels were found in 75.0% cases of partial response and 43.48% of stabilized patients, whereas the absence of any significant changes in 25 and 66.7%, respectively. There was no association between serotonin levels and the disease behavior under treatment.<bold>Conclusion</bold>: CgA could be used as a sensitive marker of NET progression on chemotherapy.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность</bold>. Целесообразность использования биохимических маркеров в контроле эффективности лечения больных нейроэндокринными опухолями (НЭО) не вызывает сомнений. Однако до сих пор отсутствуют четкие критерии оценки клинически значимых изменений уровней основных маркеров НЭО – хромогранина А (ХгА) и серотонина. <bold>Цель</bold> – оценить значимость серийного определения ХгА и серотонина в сыворотке крови для мониторинга эффективности лечения больных НЭО. <bold>Материал и методы</bold>. Определение ХгА и серотонина в сыворотке крови выполнено у 107 больных НЭО при первичном обследовании и в динамике через 3–4 недели после проведения курса лечения (химиотерапия, биотерапия), а также у 60 практически здоровых людей. Использовали иммуноферментный анализ на основе тест-систем Chromogranin A NEOLISA (Euro Diagnostica) и Serotonin ELISA (IBL International GmbH). <bold>Результаты</bold>. Выявлена связь уровней ХгА с эффектом химиотерапии у больных НЭО. При прогрессировании заболевания медиана ХгА статистически значимо повышалась (с 412 до 2679 нг/мл, p=0,012), тогда как при частичном ответе наблюдали ее снижение (с 811 до 254 нг/мл, p=0,023). По данным ROC-анализа, порог значимого изменения ХгА для прогрессирования составил 33% при чувствительности 80,0% и специфичности 95,6%. Снижение (более 33% относительно уровня до лечения) или отсутствие значимых изменений ХгА было связано со стабилизацией заболевания или частичным ответом на терапию. Значимое снижение уровней ХгА отмечено в 75,0% случаев при частичном ответе и в 43,48% – при стабилизации, отсутствие значимых изменений – в 25 и 66,7% соответственно. Для серотонина зависимости от динамики аболевания на фоне лечения не установлено. <bold>Заключение</bold>. ХгА может использоваться в качестве чувствительного маркера прогрессирования НЭО на фоне химиотерапевтического лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>neuroendocrine tumor</kwd><kwd>chemotherapy</kwd><kwd>monitoring</kwd><kwd>biomarker</kwd><kwd>chromogranin A</kwd><kwd>serotonin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нейроэндокринная опухоль</kwd><kwd>химиотерапия</kwd><kwd>мониторинг</kwd><kwd>биохимические маркеры</kwd><kwd>хромогранин А</kwd><kwd>серотонин</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
