Обследовано 50 первичных пациентов с НЭО поджелудочной железы и 42 практически здоровых донора. Определение маркеров проводили в образцах сыворотке крови с использованием стандартизованных иммуноферментных тест-систем (Chromogranin A NEOLISA, Eurodiagnostica; Human Chromogranin B, USCN). Уровни ХгА и ХгВ при НЭО поджелудочной железы достоверно отличались от контрольной группы. При этом для ХгА выявлена связь с распространенностью процесса, тогда как ХгВ продемонстрировал свойства маркера, независимого от распространенности опухоли. При изолированном использовании диагностическая чувствительность ХгА составила 76 %, ХгВ – 68 %. При комплексном определении ХгА и ХгВ диагностическая чувствительности достигала 84 %. Полученные данные свидетельствуют о потенциальной возможности применения комплекса ХгА и ХгВ в диагностике НЭО поджелудочной железы.</p></abstract><trans-abstract xml:lang="en"><p>For the first time in Russia a comparative study of chromogranin A (CgA) and chromogranin B (CgB) in neuroendocrine tumors (NETs) of the pancreas was performed. We examined 50 primary patients with pancreatic NETs and 42 healthy people. The determination of CgA and CgB was performed in blood serum using standard enzyme-linked immunoassay test-systems (Chromogranin A NEOLISA, Eurodiagnostica; Human Chromogranin B, USCN). The levels of CgA and CgB in pancreatic NETs significantly differed from the control group. There was found the association between CgA levels and the dissemination of the process, while CgB demonstrated the properties of a marker independent from the tumor dissemination. The diagnostic sensitivity of CgA was 76 %, CgB – 68 %. Complex determination of CgA and CgB enhanced the diagnostic sensitivity to 84 %. Our data indicate the potential usefulness of complex CgA and CgB in the diagnosis of pancreatic NETs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хромогранин А</kwd><kwd>хромогранин В</kwd><kwd>биохимический маркер</kwd><kwd>нейроэндокринная опухоль</kwd><kwd>поджелудочная железа</kwd><kwd>диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chromogranin A</kwd><kwd>chromogranin B</kwd><kwd>biochemical marker</kwd><kwd>neuroendocrine tumors</kwd><kwd>diagnosis</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">Orditura M., Petrillo A., Ventriglia J., Laterza M.
