The problem of drug resistance developing through complex mechanisms with complicated molecular interactions remains important. Special consideration is given to epigenetic processes. Detailed studies aimed at combinations of different antitumor agents and identification of optimal risk-adapted therapy using epigenetic markers are necessary.</p> <p>The article presents a literature review on the problem of multiple myeloma drug resistance and a clinical observation demonstrating efficacy of elotuzumab in combination with lenalidomide and dexamethasone (Elo-Rd regimen) in a patient after 1<sup>st</sup>-line therapy with bortezomib (VCD). Partial remission persisting for 3 years in combination with satisfactory tolerability, good quality of life, and absence of significant adverse events allows to hope for a favorable prognosis in the patients with bortezomib resistance.</p></abstract><trans-abstract xml:lang="ru"><p>Множественная миелома, несмотря на достигнутые успехи в терапии, характеризуется рецидивирующим или рефрактерным течением. Актуальной остается проблема лекарственной резистентности опухоли, развитие которой обусловлено комплексными механизмами со сложными молекулярными взаимодействиями. Особое внимание уделяется эпигенетическим процессам. Целесообразны проведение глубоких исследований, направленных на изучение комбинаций противоопухолевых агентов и поиск оптимальной риск-адаптированной терапии с применением эпигенетических маркеров.</p> <p>В статье представлены обзор литературы по актуальной проблеме лекарственной резистентности множественной миеломы и данные клинического наблюдения, демонстрирующие эффективность применения элотузумаба в комбинации с леналидомидом и дексаметазоном (режим Elo-Rd) у пациента после 1 линии предшествующего лечения бортезомибом (VCD). Сохраняющаяся в течение 3 лет частичная ремиссия в совокупности с удовлетворительной переносимостью, хорошим качеством жизни и отсутствием значимых нежелательных явлений позволяет надеяться на благоприятный прогноз у пациента с резистентностью к бортезомибу.</p></trans-abstract><kwd-group xml:lang="en"><kwd>recurrent/refractory multiple myeloma</kwd><kwd>bortezomib</kwd><kwd>drug resistance</kwd><kwd>elotuzumab</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рецидивирующая/рефрактерная множественная миелома</kwd><kwd>бортезомиб</kwd><kwd>лекарственная резистентность</kwd><kwd>элотузумаб</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Manni S., Carrino M., Semenzato G., Piazza F.
