Это позволяет оценить эффективность лечения in vivo, у части больных уменьшить объем локального лечения, а также оценить прогноз и при наличии резидуальной опухоли назначить адъювантную лекарственную терапию. В исследовании изучалась прогностическая значимость оценки ответа опухоли на лечение по системе RCB (Residual Cancer Burden), а также оценены уровень Ki-67 и содержание инфильтрирующих опухоль лимфоцитов (ИОЛ) в резидуальной опухоли у больных первично операбельным РМЖ с тройным негативным фенотипом (ТН РМЖ), получавших НА платиносодержащую химиотерапию (ХТ). Показано, что комплексная оценка показателей RCB, Ki-67 и ИОЛ позволяет получить более точную прогностическую информацию, чем простая констатация наличия или отсутствия резидуальной опухоли, и выделить группы больных для эскалации и де-эскалации адъювантной системной терапии.</p></abstract><trans-abstract xml:lang="en"><p>Neoadjuvant chemotherapy is a widely used approach in patients with early triple-negative and Her2-positive breast cancer (BC). This allows in vivo evaluation of treatment efficacy and reduction of the local treatment extent in some patients, as well as prognosis assessment and the prescription of adjuvant chemotherapy in patients with residual tumors. The study evaluated the predictive value of estimating tumor response to treatment using the RCB (Residual Cancer Burden) staging system and assessed Ki-67 levels and tumor-infiltrating lymphocyte (TIL) concentrations in residual tumors in patients with primary operable BC with triple-negative phenotype (TN BC) receiving neoadjuvant platinum-based chemotherapy. The study revealed that complex assessment of the RCB, Ki-67, and TILs parameters provides more accurate predictive information compared to simply asserting the presence or absence of a residual tumor, and allows assignment of patients to escalation or de-escalation of adjuvant systemic therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>тройной негативный фенотип</kwd><kwd>резидуальная опухоль</kwd><kwd>RCB</kwd><kwd>Ki-67</kwd><kwd>ИОЛ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>triple-negative phenotype</kwd><kwd>residual tumor</kwd><kwd>RCB</kwd><kwd>Ki-67</kwd><kwd>TILs</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">Fisher B, Brown A, Mamounas E, et al.
