Approximately 50% of patients do not achieve near-complete tumor regression with standard neoadjuvant antitumor therapy. New approaches are needed to minimize the adverse effects of targeted therapies and maintain their effectiveness. One solution is cytokine-based gene therapy, which uses a combination of interferon gamma and a recombinant tumor necrosis factor (TNF)/thymosin α1 hybrid.</p> <p><bold>CASE DESCRIPTION:</bold> A female patient with histologically confirmed non-luminal, HER2/neu-positive breast cancer (cT2N3M0, stage III; estrogen receptor: 0, progesterone receptor: 0, HER2/neu 3+, Ki67 70%) received two treatment cycles of paclitaxel, trastuzumab, and pertuzumab and presented due to poor treatment tolerance. Cytokine-based genetic therapy (interferon gamma + recombinant TNF/thymosin α1) was added to the standard treatment regimen. The quality of life improved after two cycles of combined treatment. Complete tumor regression in the breast, as well as in the axillary and supraclavicular lymph nodes, was confirmed after eight treatment cycles through mammography, computed tomography, and a histopathological examination of the resected breast tissue. The treatment resulted in an increase in TNFα levels and Karnofsky Performance Scale Index. The patient is still receiving maintenance circles of cytokine-based gene therapy.</p> <p><bold>CONCLUSION:</bold> The addition of cytokine-based genetic therapy to the neoadjuvant regimen improved patients’ quality of life, increased the effectiveness of antitumor treatment, and resulted in complete tumor regression.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Лечение HER2/neu-позитивного рака молочной железы представляет значительные трудности. Почти у 50% больных при использовании стандартной неоадъювантной противоопухолевой терапии не удаётся добиться полной регрессии опухоли. Представляется актуальным поиск новых подходов для преодоления ограничений таргетной терапии, снижения побочных эффектов противоопухолевого лечения без потери его эффективности. Одним из таких направлений может явиться использование препаратов цитокиногенетической терапии — интерферона гамма и гибридного препарата рекомбинантного фактора некроза опухолей тимозина α1.</p> <p><bold>Описание клинического случая.</bold> Пациентка с гистологически подтверждённым раком молочной железы сТ2N3М0 III стадии, нелюминальным, НER2/neu позитивным (ЭР 0, ПР 0, НER2/neu 3+, Кi67 70%) прошла 2 курса лечения по схеме «паклитаксел, трастузумаб и пертузумаб» и обратилась в клинику в связи с плохой переносимостью проводимой терапии. Пациентке на фоне продолжения стандартного противоопухолевого лечения была назначена цитокиногенетическая терапия препаратами интерферона гамма и рекомбинантного фактора некроза опухолей тимозина α1. После 2-х курсов сочетанной терапии пациентка отметила улучшение качества жизни. После 8-го курса лечения удалось добиться полной регрессии опухоли в молочной железе, подмышечных и надключичных лимфоузлах, подтверждённой данными маммографии, компьютерной томографии и морфологическим исследованием удалённой ткани молочной железы. На фоне проводимого лечения отмечен рост показателя ФНОα и индекса Карновского. В настоящее время пациентка продолжает получать поддерживающие курсы цитокиногенетической терапии.</p> <p><bold>Заключение.</bold> Включение препаратов цитокиногенетической терапии в состав неоадъювантной лекарственной терапии позволило улучшить качество жизни пациентки, потенцировать действие противоопухолевых препаратов и добиться полной регрессии опухоли.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cytokine-based gene therapy</kwd><kwd>interferon gamma</kwd><kwd>tumor necrosis factor alpha</kwd><kwd>breast cancer</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>цитокиногенетическая терапия</kwd><kwd>интерферон гамма</kwd><kwd>фактор некроза опухоли альфа</kwd><kwd>рак молочной железы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Merabishvili VM, Semiglazov VF, Komyakhov AV, et al.
