Молекулярные маркеры химиорезистентности позволят определять прогноз заболевания и чувствительность опухоли к лекарственным препаратам.</p><sec><title>Цель</title><p>Цель. Оценить предиктивную значимость экспрессии факторов TGFb1 и CXCL8 – регуляторов опухоль-ассоциированного воспаления в опухолевой ткани при КРР.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Пациенты были разделены на три группы: I – без рецидива, II – с рецидивом (в течение 6–16 мес после окончания химиотерапии), III – с прогрессированием заболевания. Экспрессию TGFb1 и CXCL8 в опухолевой ткани до начала лечения пациентов с КРР на II–III стадии (n = 77) определяли с использованием количественной полимеразной цепной реакции в реальном времени на амплификаторе CFX-96 BioRad (США). Статистическая обработка данных выполнена с использованием программного обеспечения Statistica 13.0 (StatSoft, США).</p></sec><sec><title>Результаты</title><p>Результаты. В образцах низкодифференцированных опухолей при КРР уровень мРНК TGFb и CXCL8 был существенно выше, чем в опухолевых образцах с умеренной и высокой дифференцировкой. Зависимости уровня транскриптов TGFb1 и CXCL8 в образцах опухоли у пациентов на II–III стадии КРР от возраста и наличия мутаций EGFR (Epidermal Growth Factor Receptor) сигнального пути (RAS, BRAF) не выявлено. Установлена положительная сильная корреляционная связь между уровнями транскриптов TGFb1 и CXCL8 для всей выборки пациентов с КРР. Экспрессия генов TGFb1 и CXCL8 значимо выше в опухолевой ткани пациентов с прогрессированием заболевания.</p></sec><sec><title>Заключение</title><p>Заключение. Гиперэкспрессия TGFb1 и CXCL8, участвующих в механизме опухоль-ассоциированного воспаления, может рассматриваться как негативный фактор прогноза времени без прогрессирования при использовании схемы FOLFOX/XELOX лечения колоректального рака.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Colorectal cancer is ranked third in terms of incidence and second in terms of mortality around the world. Molecular markers of chemoresistance allow to determine the prognosis of the disease and sensitivity of the tumor to drugs.</p></sec><sec><title>Aim</title><p>Aim. To assess the predictive value of expression of regulators of tumor-associated inflammation TGFb1 and CXCL8 in the tumor tissue in colorectal cancer.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Patients were divided into 3 groups: group I included patients without relapse of the disease, group II encompassed patients with relapse of the disease (within 6–16 months after the end of chemotherapy), group III included patients with disease progression. Expression of TGFb1 and CXCL8 in the tumor tissue before treatment in patients with stage II–III colorectal cancer (n = 77) was determined using quantitative realtime polymerase chain reaction (PCR) on the Bio-Rad CFX-96 Touch Real-Time PCR Detection System (USA). Statistical data processing was performed using Statistica 13.0 software (StatSoft, USA).</p></sec><sec><title>Results</title><p>Results. We found that in samples of poorly differentiated colorectal cancer, the level of TGFb and CXCL8 mRNA was significantly higher than in moderately and well differentiated tumors. We did not reveal any relationship of the level of TGFb1 and CXCL8 transcripts in tumor samples of patients with stage II–III colorectal cancer with age and the presence of mutations in the EGFR (Epidermal Growth Factor Receptor) signaling pathway (RAS, BRAF). We found a strong positive correlation between the levels of TGFb1 and CXCL8 transcripts for the entire sample of patients with colorectal cancer. We have found that the expression of TGFb1 and CXCL8 genes was significantly higher in the tumor tissue of patients with disease progression.</p></sec><sec><title>Conclusion</title><p>Conclusion. Overexpression of TGFb1 and CXCL8, which are involved in the mechanism of tumor-associated inflammation, can be considered as a negative prognostic factor for the progression-free interval when using the FOLFOX / XELOX regimen for the treatment of colorectal cancer.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>колоректальный рак</kwd><kwd>TGFb1</kwd><kwd>CXCL8</kwd><kwd>EGFR</kwd><kwd>опухолевая прогрессия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colorectal cancer</kwd><kwd>CXCL8</kwd><kwd>TGFb1</kwd><kwd>EGFR</kwd><kwd>tumor progression</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">Dekker E., Tanis P.J., Vleugels J.L.A., Kasi P.M., Wallace M.B.
