They were divided into 2 groups depending on the NAC provided, and then they were subdivided depending on the completion of the course of ongoing NAC, the final pathomorphological result and the presence of recurrence.</p><p><bold>   Results. </bold>Group I included 48 (64 %) patients who received the AC–T regimen; in group II (n = 27 (36 %)) patients received NAC according to the AC–TCarb regimen. Patients of group II showed a higher frequency of achieving pathological complete response (pCR) compared with patients of group I (73.7 % versus 41.2 %, respectively, p = 0.0433). Taking into account the NAC regimens being carried out, patients of group I had a slightly higher risk of recurrence compared to patients of group II (p = 0.099).</p><p><bold>   Conclusion. </bold>In patients with primary BRCA-associated TNBC, the addition of platinum compounds to the systemic NAC resulted in achieving of pCR in 73.7 % cases compared with 41.2 % pCR after the standard anthracycline-taxane NAC, which entails a reduced risk recurrence in this category of patients. Performing a full course of planned NAC has a positive trend in achieving pCR in patients of this category.</p></abstract><trans-abstract xml:lang="ru"><p><bold>   Введение.</bold> BRCA-ассоциированный трижды негативный рак молочной железы (тНРмЖ) считается одним из самых агрессивных подтипов рака молочной железы при высокой чувствительности к химиотерапии, что обусловливает повышенный интерес к поиску новых вариантов лечения пациентов с этим подтипом рака.</p><p><bold>   Цель исследования </bold>– определить роль добавления препарата платины к стандартной системной неоадъювантной химиотерапии (НаХт) у пациентов с первичным BRCA-ассоциированным тНРмЖ с клинической стадией T1–3N0–3M0 и оценить влияние препаратов платины на безрецидивную выживаемость у больных данной категории.</p><p><bold>   Материалы и методы. </bold>В исследование включено 75 пациентов с диагнозом первичного BRCA-ассоциированного тНРмЖ, которые были распределены на 2 группы в зависимости от схемы проводимой НаХт и далее на подгруппы в зависимости от завершенности курса проводимой НаХт, конечного патоморфологического результата и наличиярецидивов.</p><p><bold>   Результаты. </bold>В I группу вошли 48 (64  %) пациентов, получивших схему ас–т, во II группе пациенты (n = 27 (36 %)) получали НаХт по схеме ас–TCarb. Пациенты II группы показали более высокую частоту достижения полного патоморфологического ответа (pCR) по сравнению с пациентами I группы (73,7 % против 41,2 % соответственно, p = 0,0433). С учетом схем проводимой НаХт пациенты I группы имели несколько более высокий риск развития рецидива по сравнению с пациентами II группы (p = 0,099).</p><p><bold>   Выводы.</bold> У больных первичным BRCA-ассоциированным тНРмЖ добавление препаратов платины к схеме НаХт приводит к достижению pCR в 73,7 % случаев по сравнению с 41,2 % частотой достижения pCR после проведения стандартной антрациклин-таксановой НаХт, что влечет за собой снижение риска возникновения рецидивов у данной категории пациентов. Проведение полного курса запланированной НаХт имеет положительную тенденцию по достижению pCR у больных данной категории.</p></trans-abstract><kwd-group xml:lang="en"><kwd>BRCA1 / 2 mutation</kwd><kwd>triple-negative breast cancer</kwd><kwd>breast cancer recurrence</kwd><kwd>platinum preparations</kwd><kwd>complete pathomorphological regression</kwd><kwd>neoadjuvant chemotherapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>BRCA1 / 2 мутация</kwd><kwd>трижды негативный рак молочной железы</kwd><kwd>рецидив рака молочной железы</kwd><kwd>препараты платины</kwd><kwd>полный патоморфологический ответ</kwd><kwd>неоадъювантная химиотерапия</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This study has been supported by the Russian Science Foundation (grant No. 22-15-0266)</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (грант № 22-15-0266)</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
