Изучить влияние делеционного полиморфизма генов глутатион-S-трансфераз (GSTT1, GSTM1), на эффективность химиотерапии (ХТ) у пациенток с диагнозом рак молочной железы (РМЖ) в Приморском крае. Материалы и методы. Обследовано 132 пациентки с диагнозом РМЖ в возрасте от 23 до 79 лет (средний возраст – 48 ± 13 лет), получивших химиотерапевтическое лечение. Генотипирование полиморфных вариантов GSTM1 и GSTT1 проводили с помощью мультиплексной полимеразной цепной реакции с последующим анализом кривых плавления продуктов реакции.Результаты. Безрецидивная выживаемость (БРВ) больных РМЖ с «нулевым» генотипом GSTT1 была статистически значимо выше (116,7 месяца (9,6 года) против 75,8 месяца (6,2 года)), чем у пациенток с «нормальным» генотипом GSTT. Так, в случае «нулевого» генотипа GSTT1 риск рецидива заболевания снижался в 2,4 раза (ОР = 0,418, ДИ = 0,191–0,915, р = 0,024). Как и в случае с GSTT1, БРВ больных с «нулевым» генотипом GSTM1 возрастала с 72,7 месяца (6 лет) до 76,1 месяца (6,3 года). При этом риск рецидива заболевания у носителей «нулевого» генотипа GSTM1 снижался в 1,7 раза (ОР = 0,596, ДИ = 0,369–0,964, р = 0,033) по сравнению с таковым у носителей «нормального» генотипа GSTM1.Заключение. Делеционный полиморфизм генов GSTT1 и GSTM1 оказывает значительное влияние на эффективность ХТ пациентов с РМЖ. Носители «нулевых» генотипов демонстрировали более высокую БРВ и меньший риск развития рецидива заболевания. Дальнейшие исследования в данном направлении и валидация полученных данных могут позволить индивидуализировать лечение пациентов с РМЖ, оптимизировать схемы ХТ и снизить число нежелательных явлений.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To study the effect of deletion polymorphism of the GST genes (GSTT1, GSTM1) on chemotherapy (CT) efficacy in women diagnosed with breast cancer (BC) in the Primorsky Krai. Materials and methods. The study involved 132 women with breast cancer aged 23 to 79 years (mean age 48 ± 13 years) who received chemotherapy treatment. The detection of deletion (null) genotypes of GSTM1 and GSTT1 was carried out using multiplex PCR followed by an analysis of the melting curves of the reaction products. Results. Relapse-free survival (RFS) of BC patients with the “null” GSTT1 genotype was statistically significantly higher (116.7 months (9.6 years) versus 75.8 months (6.2 years)) than in patients with the “normal” GSTT genotype. Thus, in the case of the GSTT1“null” genotype, the risk of disease relapse decreased by 2.4 times (HR = 0.418, CI = 0.191–0.915, p = 0.024). Similar to GSTT1, the DFS of patients with the GSTM1 null genotype increased from 72.7 months (6 years) to 76.1 months (6.3 years). At the same time, the risk of disease relapse in carriers of the “null” GSTM1 genotype decreased by 1.7 times (HR = 0.596, CI = 0.369–0.964, p = 0.033) compared with that in carriers of the “normal” GSTM1 genotype. Conclusions. Deletion polymorphism of the GSTT1 and GSTM1 genes has a significant impact on chemotherapy efficacy in breast cancer patients. Carriers of “null” genotypes demonstrated a higher RFS and a lower risk of developing disease relapse. Further research in this direction and validation of the data obtained may contribute to individualizing the treatment of breast cancer patients, optimizing chemotherapy regimens, and reducing the number of adverse events.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>генетический полиморфизм</kwd><kwd>гены GSTT1</kwd><kwd>GSTM1</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mbreast cancer</kwd><kwd>genetic polymorphism</kwd><kwd>GSTT1</kwd><kwd>GSTM1 genes</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">Сычёв Д.А., Мошетова Л.К.
