The article presents the current state of the problem of the combination of BC and pregnancy, the impact of pregnancy on the course and outcome of breast oncopathology, as well as modern hypotheses for the development of breast cancer during pregnancy. It is shown that the current studies are quite contradictory and in many ways not accurate enough in methodology and materials. We present a clinical case of BC associated with pregnancy. The case is interesting from 2 positions: on the one hand, the patient’s tumor process is associated with pregnancy, on the other hand, there is a very rare combination of HER2/neu- and <italic>BRCA1</italic>-positive status.</p><p>According to the presented literature data and our own data, it was concluded that the treatment of patients with BC during pregnancy is a difficult task and is often accompanied by tumor progression, despite the standard treatment regimens. Undoubtedly, this group of patients needs to develop new methodological approaches to antitumor treatment based on a deep analysis of the molecular genetic characteristics of the tumor, the hormonal background in general, and its effect on the tumor process during pregnancy. Such a personalized approach will improve the results of treatment of young patients with BC during pregnancy.</p></abstract><trans-abstract xml:lang="ru"><p>Рак молочной железы (РМЖ) занимает 2-е место по заболеваемости и 1-е ранговое место по показателю смертности среди онкопатологии у женщин. В статье представлено современное состояние проблемы сочетания рака и беременности, освещены вопросы влияния беременности на течение и исход онкопатологии молочной железы, а также современные гипотезы развития РМЖ на фоне беременности. Показано, что текущие исследования достаточно противоречивы и во многом недостаточно точны в методологии и материалах. В работе представлен клинический пример течения РМЖ, ассоциированного с беременностью. случай интересен сразу с 2 позиций: с одной стороны, у пациентки опухолевый процесс ассоциирован с беременностью, с другой – имеется очень редкий вариант сочетания HER2/neu- и <italic>BRCA1</italic>-положительного статуса.</p><p>На основании данных литературы и собственных наблюдений сделан вывод о том, что лечение пациенток с РМЖ на фоне беременности является сложной задачей и часто сопровождается опухолевым прогрессированием, несмотря на проводимое по стандартным режимам лечение. Безусловно, данная группа пациенток нуждается в разработке новых методологических подходов к противоопухолевому лечению, основанных на глубоком анализе молекулярно-генетических особенностей опухоли, гормонального фона в целом и его влияния на опухолевый процесс при беременности. Подобный персонализированный подход позволит улучшить результаты лечения молодых больных РМЖ на фоне беременности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pregnancy</kwd><kwd>breast cancer</kwd><kwd>prognosis</kwd><kwd>tumor process</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>беременность</kwd><kwd>рак молочной железы</kwd><kwd>прогноз</kwd><kwd>течение опухолевого процесса</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was performed without external funding</funding-statement><funding-statement xml:lang="ru">Работа выполнена без спонсорской поддержки</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">The stаte of oncologicаl cаre to the populаtion of Russiа in 2021.
