Исследования биомаркеров остаются востребованными в области онкологии на протяжении десятилетий, однако число рекомендуемых, клинически значимых сывороточных маркеров не увеличивается. Цель работы - изучить роль сывороточных биомаркеровколоректальныхаденокарцином разной степени дифференцировки у пациентов казахской популяции. Для исследования использовали иммунофлуоресцентный метод с использованием технологии XMap, который включал в себя одновременное определение AFP, CA 125, CA 15-3, CA 19-9, CEA, CYFRA 21-1, HE4, остеопонтин. В результате AFP, СА 125, CA15-3 не показали различий, связанных с дифференцировкой опухолевой ткани. CEA в проведенном исследовании подтвердил свою зависимость от степени дифференцировки, но не отреагировал в случае высокодифференцированной аденокарциномы. Уровень CA 19-9 был выше только в группах аденокарцином умеренной и низкой степени дифференцировки. Рассмотрение всех конфаундинг-факторов позволит лучше понять биологию биомаркеров рака, усовершенствовать их интерпретацию и показания к применению.</p></abstract><trans-abstract xml:lang="en"><p>Despite the existing screening programs for colorectal cancer, new markers are still being developed, including serum biomarker panels for early diagnosis, and in patients with a verified disease, panels for assessing the prognosis and probability of metastasis. Biomarker research has remained in demand in the field of Oncology for decades, but the number of recommended, clinically significant serum markers has not increased. Objective - to study the role of serum biomarkers of colorectal adenocarcinomas of different degrees of differentiation in patients of the Kazakh population. For the study, it was used an immunofluorescence method through XMap technology, which included simultaneous determination of AFP, CA 125, CA 15-3, CA 19-9, CEA, CYFRA 21-1, HE4, and osteopontin. As a result, AFP, CA 125, and CA15-3 did not show differences related to tumor tissue differentiation.The CEA in our study confirmed dependence on the degree of differentiation, but did not respond in the case of highly differentiated adenocarcinoma.The level of CA 19-9 was higher only in the groups of moderate and low-grade adenocarcinomas. Consideration of all confounding factors will allow us to better understand the biology of cancer biomarkers and improve their interpretation and indications for use.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>онкомаркеры</kwd><kwd>аденокарцинома</kwd><kwd>колоректальный рак</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cancer markers</kwd><kwd>adenocarcinoma</kwd><kwd>colorectal cancer</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">Показатели онкологической службы Республики Казахстан за 2017 год (статистические материалы).
