Гиперэкспрессия Her2neu встречается у 15–20 % больных раком желудка и коррелирует с неблагоприятным течением заболевания. Описание клинического случая. Представлен клинический случай полной морфологической регрессии резектабельной опухоли желудка с гиперэкспрессией Her2/ neu. Пациент получил комбинированное лечение, включающее 8 курсов неоадъювантной химиотерапии по схеме mFLOT + трастузумаб с последующим хирургическим вмешательством в объёме R0- резекции. Добавление таргетной терапии не оказало негативного влияния на течение периоперационного периода. При плановом морфологическом исследовании операционного материала получено заключение о полном лечебном патоморфозе опухоли (Mandart TGR1). К настоящему времени пациент наблюдается в течение 27 мес без признаков рецидива заболевания. Заключение. Тотальная неоадъювантная химиотерапия по схеме mFLОТ с трастузумабом при операбельном раке желудка с гиперэкспрессией Her2/neu позволяет надеяться на улучшение отдалённых результатов лечения.</p></abstract><trans-abstract xml:lang="en"><p>Background. Overexpression of Her2neu occurs in 15–20% of patients with gastric cancer and correlates with an unfavorable prognosis. Case report. We report a case of pathological complete regression of resectable gastric cancer with Her2/neu overexpression. The patient received combined modality treatment including 8 cycles of neoadjuvant chemotherapy with mFLOT + trastuzumab followed by R0 resection. The addition of targeted therapy did not have a negative impact on the perioperative period. Histolohical examination of the surgical specimen revealed pathological complete response (Mandart TGR1). Currently, the patient has been followed-up for 27 months without signs of disease relapse. Conclusion. Total neoadjuvant chemotherapy with mFLОТ+ trastuzumab for operable gastric cancer with Her2/neu overexpression allows us to hope for improved long-term treatment outcomes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>гиперэкспрессия Her2neu</kwd><kwd>комбинированное лечение</kwd><kwd>неоадъювантная терапия</kwd><kwd>полная регрессия опухоли</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric cancer</kwd><kwd>Her2/neu overexpression</kwd><kwd>combined modality treatment</kwd><kwd>neoadjuvant therapy</kwd><kwd>complete tumor regression</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">Sung H., Ferlay J., Siegel R.L., Laversanne M., Soerjomataram I., Jemal A., Bray F.
