В настоящей работе мы использовали данные, полученные при анализе 1083 образцов РМЖ в рамках проекта TCGA-BRCA, для определения влияния экспрессии LTB4R на эффективность лечения циклофосфамидом. Анализ кривых выживаемости пациенток с трижды-негативным (ТН) РМЖ с высокой экспрессией LTB4R в опухолях показал увеличение общей выживаемости при лечении циклофосфамидом (p&lt;0,05). Для LumB подтипа РМЖ эффект циклофосфамида не зависел от экспрессии LTB4R. Полученные результаты расширяют возможности персонализации терапии РМЖ.</p></abstract><trans-abstract xml:lang="en"><p>Based on the results of genome-wide screening of differential methylation in breast cancer samples (BC), we have identified abnormal demethylation of the LTB4R leukotriene receptor gene CpG island, which can lead to its ectopic expression. In this paper, we used the data obtained for 1083 BC samples under the TCGA-BRCA project to determine impact of LTB4R expression on the effectiveness of treatment with cyclophosphamide. Analysis of survival curves for patients with triple-negative (TN) breast cancer and high expression of LTB4R showed an increase in overall survival of patients treated with cyclophosphamide (p &lt;0.05). For LumB BC subtype, the effect of cyclophosphamide was not dependent on LTB4R expression. The results obtained expand the possibilities of personalizing BC therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>лейкотриеновые рецепторы</kwd><kwd>метилирование ДНК</kwd><kwd>циклофосфамид</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>leukotriene receptors</kwd><kwd>DNA methylation</kwd><kwd>chemotherapy drugs</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
