В этой связи актуальным является поиск новых предсказательных факторов и маркеров, которые позволили бы с высокой вероятностью не только прогнозировать эффект НХТ, но и адекватно выбирать схему лечения для конкретного пациента. Цель исследования – изучение связи уровня экспрессии генов химиочувствительности с эффективностью неоадъювантной химиотерапии у больных немелкоклеточным раком легкого. материал и методы. В исследование были включены 30 больных НМРЛ IIA–IIIB стадии. Из биопсийного материала нормальной и опухолевой тканей легкого до НХТ выделяли РНК. Уровень экспрессии генов химиочувствительности BRCA1, RRM1, ERCC1, TOP1, TOP2a, TUBB3, TYMS, GSTP1 оценивали при помощи обратно-транскриптазной количественной ПЦР в режиме реального времени (RT-qPCR). Результаты. Анализ показателей экспрессии изучаемых генов позволил установить значимые различия в группах больных с разным эффектом НХТ. В 67 % случаев (10/15) отсутствие экспрессии ERCC1 обусловливает наличие объективного ответа на лечение, по сравнению с группой, где присутствует экспрессия (p&lt;0,05). Наличие низкого (менее 0,2) и высокого (более 1,2) уровня экспрессии BRCA1 сопряжено с низкими показателями эффективности НХТ, по сравнению с группой больных, у которых уровень эффективности находился в пределах нижней и верхней границы тертилей. Также статистически значимые различия были показаны для генов GSTP1 и RRM1. заключение. Таким образом, комплексная оценка экспрессии генов химиочувствительности важна не только с точки зрения понимания молекулярной биологии НМРЛ, но и для более точного определения эффекта НХТ и обнаружения потенциальных мишеней для лекарственных средств.</p></abstract><trans-abstract xml:lang="en"><p>The objective response rate to neoadjuvant chemotherapy (NAC) in patients with non-small cell lung cancer (NSCLC) is approximately 16 %. Therefore, the search for new predictive factors and markers that could precisely predict the NAC response and be relevant to the choice of the adequate treatment policy is of utmost importance. the purpose of the study was to analyze the relationship between the expression levels of chemosensitivity genes and NAC response in patients with non-small cell lung cancer. material and methods. The study included 30 patients with stage IIAIIIB NSCLC. Total RNA was isolated from normal and tumor lung tissue samples prior to NAC. The expression level of chemosensitivity genes, such as BRCA1, RRM1, ERCC1, TOP1, TOP2a, TUBB3, TYMS, and GSTP1 was evaluated by real-time reverse transcriptase quantitative PCR (RT-qPCR). results. A significant difference in the expression levels of the studied genes between patients with different NAC response was found. The objective response to therapy was observed in 67 % (10/15) of patients having no ERCC1 expression compared to those with ERCC1 expression (p&lt;0.05). Low (less than 0.2) and high (more than 1.2) BRCA1 expression levels were associated with low rates of NAC response compared with patients whose expression level was between the lower and upper quartiles. Statistically significant differences were shown for the GSTP1 and RRM1 genes. conclusion. A comprehensive assessment of the expression of chemosensitivity genes is important not only in terms of understanding heterogeneity and complexity of the molecular biology of NSCLC, but also for more accurate prediction of response to NAC and identification of potential drug targets.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>немелкоклеточный рак легкого</kwd><kwd>неоадъювантная химиотерапия</kwd><kwd>эффективность химиотерапии</kwd><kwd>гены химиочувствительности</kwd><kwd>экспрессия генов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-small cell lung cancer</kwd><kwd>neoadjuvant chemotherapy</kwd><kwd>response to chemotherapy</kwd><kwd>chemosensitivity genes</kwd><kwd>gene expression</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">Felip E., Rosell R., Maestre J.A., Rodríguez-Paniagua J.M., Morán T., Astudillo J., Alonso G., Borro J.M., González-Larriba J.L., Torres A., Camps C., Guijarro R., Isla D., Aguiló R., Alberola V., Padilla J., Sánchez-Palencia A., Sánchez J.J., Hermosilla E., Massuti B.; Spanish Lung Cancer Group.
