Despite advances in the treatment of plasma cell dyscrasias, determining optimal approaches to treating ALA patients remains a challenging task. Research results and real-world clinical practice data indicate the advantage of using a combination of daratumumab with a bortezomib-containing regimen over other programs in achieving an antitumor response, increasing progression-free survival, while remaining a highly effective treatment option with a favorable safety profile in most patients. It is advisable to study the prognostic role of minimal residual disease in ALA patients and its correlation with the achieved hematological and organ responses at different treatment stages, as well as to search for new biological markers for patients’ risk stratification and optimization of antitumor therapy.</p> <p>Clinical case of a patient with stage II ALA are presented. After six cycles of Dara-VCD (daratumumab, bortezomib, cyclophosphamide, and dexamethasone), a very good partial hematologic response was recorded. Despite the fact that the patient had previously received VCD (bortezomib, cyclophosphamide, and dexamethasone) and daratumumab alone in the second line, significant treatment efficacy, along with a significant improvement in overall condition and quality of life, was achieved only with the use of bortezomib-containing therapy in combination with an anti-CD38 antibody.</p></abstract><trans-abstract xml:lang="ru"><p>AL-амилоидоз (АЛА) – заболевание, характеризующееся отложением фрагментов моноклональных свободных легких цепей иммуноглобулинов в органах с нарушением их функции. Несмотря на достигнутые успехи в терапии плазмоклеточных дискразий, определение оптимальных подходов к лечению пациентов с АЛА остается актуальной задачей. Результаты проведенных исследований и данные реальной клинической практики свидетельствуют о преимуществе использования комбинации даратумумаба с бортезомибсодержащим режимом перед другими программами в достижении противоопухолевого ответа, увеличении выживаемости без прогрессирования при высокой эффективности лечения и благоприятным профилем безопасности у большинства пациентов. Целесообразны изучение прогностической роли минимальной резидуальной болезни у больных АЛА и ее корреляции с достигнутыми гематологическим и органным ответами на разных этапах лечения, а также поиск новых биологических маркеров для стратификации пациентов на группы риска и оптимизации противоопухолевой терапии.</p> <p>Представлены результаты клинического наблюдения пациентки со II стадией АЛА, у которой после 6 циклов Dara-VCD (даратумумаб, бортезомиб, циклофосфан, дексаметазон) зафиксирован очень хороший частичный гематологический ответ. Несмотря на то что ранее больная получала VCD (бортезомиб, циклофосфан, дексаметазон), а во 2-й линии – даратумумаб в монорежиме, значимая эффективность лечения наряду с выраженным улучшением общего состояния и качества жизни достигнуты только при использовании бортезомибсодержащей терапии в комбинации с анти-CD38-антителом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>AL amyloidosis</kwd><kwd>daratumumab</kwd><kwd>Dara-VCD</kwd><kwd>very good partial hematological response</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>AL-амилоидоз</kwd><kwd>даратумумаб</kwd><kwd>Dara-VCD</kwd><kwd>очень хороший частичный гематологический ответ</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gertz M.A. Immunoglobulin light chain amyloidosis: 2026 update on diagnosis, prognosis, and treatment.
