At the same time, it is important to know whether age, in itself, determines a less favorable outcome of the disease in young patients.</p><p><bold>Aim.</bold> To evaluate overall and recurrence-free survival rates in premenopausal and postmenopausal patients who underwent various levels of surgery and received neoadjuvant and adjuvant systemic therapy.</p><p><bold>Materials and methods.</bold> Of the 3,450 analyzed patients, the final analysis included 265 patients with breast cancer (clinical stage T1–3N0–1M0) who received treatment between 2011 and 2019, who were divided into 2 groups depending on age category, biological tumor subtype, types of neoadjuvant and adjuvant treatment.</p><p><bold>Results.</bold> Of 265 included patients, 162 (61.1 %) were premenopausal women, 103 (38.9 %) were postmenopausal women. The median follow-up was 5 years. The 5-year overall survival was 96.8 % (95 % confidence interval (CI) 92.6–98.7) in premenopausal patients and 95.1 % (95 % CI 88.5–97.9) in postmenopausal patients. The differences in overall survival estimated using the likelihood ratio test were not statistically significant (<italic>p</italic> = 0.927). The 5-year recurrencefree survival rate was 77.6 % (95 % CI 70.3–83.3) in premenopausal patients and 84.2 % (95 % CI 75.6–90.0) in postmenopausal patients. The differences in disease-free survival estimated using the likelihood ratio test were not statistically significant (<italic>p</italic> = 0.253).</p><p><bold>Conclusion.</bold> When comparing patients with early breast cancer, overall and relapse-free survival did not depend on menopausal status. It is necessary to conduct randomized trials to determine the effectiveness of drug therapy.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Рак молочной железы, возникающий у молодых женщин, чаще относится к биологически агрессивным подтипам (HER2+ и трижды негативный) по сравнению с постменопаузальными пациентками. При этом важно знать, предопределяет ли возраст сам по себе менее благоприятный исход заболевания у молодых пациенток.</p><p><bold>Цель исследования </bold>– оценить показатели общей и безрецидивной выживаемости у пре- и постменопаузальных пациенток, подвергавшихся хирургическому вмешательству различного объема и получивших неоадъювантную и адъювантную системную терапию.</p><p><bold>Материалы и методы.</bold> Из 3450 случаев в окончательный анализ были включены 265 пациенток с раком молочной железы (с клинической стадией T1–3N0–1M0), получавших лечение в период с 2011 по 2019 г., которых распределили на 2 группы в зависимости от возрастной категории, биологического подтипа опухоли, видов неоадъювантного и адъювантного лечения.</p><p><bold>Результаты.</bold> Из 265 включенных в анализ пациенток 162 (61,1 %) – женщины в пременопаузе, 103 (38,9 %) – женщины в постменопаузе. медиана продолжительности наблюдения составила 5 лет, пятилетняя общая выживаемость – 96,8 % (95 % доверительный интервал (ДИ) 92,6–98,7) у пременопаузальных пациенток и 95,1 % (95 % ДИ 88,5–97,9) у постменопаузальных пациенток. Различия в общей выживаемости, оцененные с помощью теста отношения правдоподобия, не были статистически значимы (<italic>p</italic> = 0,927). Пятилетняя безрецидивная выживаемость составила 77,6 % (95 % ДИ 70,3–83,3) у пременопаузальных пациенток и 84,2 % (95 % ДИ 75,6–90,0) у постменопаузальных пациенток. Различия в безрецидивной выживаемости, оцененные с помощью теста отношения правдоподобия, не были статистически значимы (<italic>p</italic> = 0,253).</p><p><bold>Выводы.</bold> При сравнении пациенток с ранним раком молочной железы общая и безрецидивная выживаемость не зависели от менопаузального статуса.
