Однако его эффективность напрямую зависит от приверженности лечению, которая часто снижается из-за нежелательных лекарственных реакций и индивидуальных различий в метаболизме препарата. В статье представлены данные исследования приверженности терапии тамоксифеном через 5 лет наблюдения во взаимосвязи с выявленными раннее фармакогенетическими ассоциациями с возникновением нежелательных лекарственных реакций. Фармакогенетическое тестирование перед назначением тамоксифена может улучшить приверженность лечения за счёт персонализации терапии и снижения частоты нежелательных лекарственных явлений.</p></abstract><trans-abstract xml:lang="en"><p>Tamoxifen is the gold standard of endocrine therapy in patients with ER+ breast cancer. However, the efficacy of tamoxifen directly depends on adherence to treatment. Adherence may decrease due to adverse drug reactions and individual differences in drug metabolism. The article presents data from a study of adherence to tamoxifen therapy after 5 years of follow-up in relation to pharmacogenetic associations and adverse drug reactions. Pharmacogenetic testing can improve adherence to treatment by personalizing therapy and reducing the incidence of adverse drug events.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тамоксифен</kwd><kwd>рак молочной железы</kwd><kwd>приверженность лечению</kwd><kwd>нежелательные лекарственные реакции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tamoxifen</kwd><kwd>breast cancer</kwd><kwd>adherence</kwd><kwd>adverse drug reactions</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">Drullinsky PR, Hurvitz SA.
