Randomised clinical trials, meta-analyses, pharmacovigilance studies and current clinical guidelines (ESMO, ASCO/ASH) were analysed for the following drug classes: antibody–drug conjugates (ADCs), PARP inhibitors (PARPi), tyrosine kinase inhibitors and immune checkpoint inhibitors.</p> <p><bold>Results.</bold> Anaemia occurs in 30–80 % of cancer patients and represents an independent prognostic factor for worse overall survival. ADC haematological toxicity is off-target and payload-driven: conjugates based on monomethylauristatin E carry the highest rates of severe anaemia. PARPi cause anaemia as a class effect via disruption of PARP-2-dependent erythroid differentiation. Tyrosine kinase inhibitors exert haematotoxicity through molecularly specific pathways, including disruption of erythrocyte membrane integrity. Immune checkpoint inhibitors are associated with immune-mediated haemolytic anaemia and aplastic syndrome. Among correction approaches, intravenous iron preparations and sucrosomial iron overcome the hepcidin-mediated functional block unachievable with classical oral salts. Erythropoiesis-stimulating agents are indicated under strict conditions given thromboembolic risk and potential immunosuppressive effects on the tumour microenvironment.</p> <p><bold>Conclusion.</bold> Pathogenetically sound correction of anaemia during targeted therapy requires a differentiated approach accounting for the development mechanism, type of iron deficiency and targeted agent class. Blood count monitoring no later than 2 weeks from the first cycle start is mandatory for patients receiving ADCs, PARPi and immune checkpoint inhibitors.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – систематизировать актуальные данные о механизмах развития анемии при применении основных классов таргетных противоопухолевых препаратов, оценить ее влияние на качество жизни и обобщить современные подходы к коррекции.</p> <p><bold>Материалы и методы.</bold> Проведен нарративный обзор литературы с поиском публикаций в базах данных PubMed, eLIBRARY и Cochrane Library без ограничений по дате. В анализ включены рандомизированные клинические исследования, метаанализы, фармаковигилансные исследования и актуальные клинические рекомендации Европейского общества медицинской онкологии, Американского общества клинической онкологии / Американского общества гематологии по следующим классам препаратов: конъюгаты антитело–лекарственное средство (АЛС), ингибиторы PARP (поли-АДФ-рибозополимераза, PARPи), тирозинкиназные ингибиторы и иммунные чекпоинт-ингибиторы.</p> <p><bold>Результаты.</bold> Анемия встречается у 30–80 % онкологических больных и является независимым прогностическим фактором ухудшения общей выживаемости. Гематологическая токсичность АЛС носит нецелевой характер и определяется природой цитотоксической нагрузки: конъюгаты на основе монометилауристатина E вызывают наибольшую частоту тяжелой анемии. PARPи вызывают анемию как класс-эффект через нарушение PARP-2-зависимого эритроидного дифференцирования. Тирозинкиназные ингибиторы реализуют гематотоксичность через молекулярно-специфические пути, включая нарушение целостности мембраны эритроцитов. Иммунные чекпоинт-ингибиторы ассоциированы с иммуноопосредованной гемолитической анемией и апластическим синдромом. Среди методов коррекции внутривенные препараты железа и сукросомальное железо преодолевают гепсидинобусловленный функциональный блок, недостижимый для классических пероральных солей. Эритропоэзстимулирующие агенты показаны строго по показаниям с учетом тромбоэмболического риска и потенциального иммуносупрессивного влияния на опухолевое микроокружение.</p> <p><bold>Заключение.</bold> Патогенетически обоснованная коррекция анемии при таргетной терапии требует дифференцированного подхода с учетом механизма ее развития, формы железодефицита и класса применяемого противоопухолевого агента. Обязательный мониторинг показателей крови не позднее 2 нед от начала первого цикла необходим для пациентов, получающих АЛС, PARPи и иммунные чекпоинт-ингибиторы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cancer-related anaemia</kwd><kwd>antibody-drug conjugates</kwd><kwd>PARP inhibitors</kwd><kwd>tyrosine kinase inhibitors</kwd><kwd>immune checkpoint inhibitors</kwd><kwd>iron deficiency</kwd><kwd>hepcidin</kwd><kwd>erythropoiesis-stimulating agent</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>анемия злокачественных новообразований</kwd><kwd>конъюгаты антитело–лекарственное средство</kwd><kwd>ингибиторы PARP</kwd><kwd>тирозинкиназные ингибиторы</kwd><kwd>иммунные чекпоинт-ингибиторы</kwd><kwd>железодефицит</kwd><kwd>гепсидин</kwd><kwd>эритропоэзстимулирующие агенты</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Knight K., Wade S., Balducci L.
