Inclusion of autologous hematopoietic stem cell transplantation (auto‑HSCT) into the program therapy in somatically safe young patients is considered in order to achieve long and deep hematologic response and prevent disability. In the published literature, there are no data from large studies on the efficacy of auto‑HSCT in the therapy of such patients. Results of long‑term observations in patients who received auto‑HSCT as a consolidation phase of therapy provide an improved understanding of the efficacy of including high‑dose chemotherapy into program treatment.</p><p><bold>   Aim. </bold>To evaluate the efficacy of auto‑HSCT in the program therapy of patients with pOEMS‑syndrome.</p><p><bold>   Materials and methods. </bold>The medical records of 687 patients with plasma cell tumors over a 22‑year period (from 2001 to 2023) were retrospectively analyzed. A retrospective, single‑center study included 4 patients with pOEMS‑syndrome who received auto‑HSCT.</p><p><bold>   Results.</bold> After induction therapy, partial hematologic response (pR) has been achieved in 100 % of cases. According to vascular endothelial growth factor monitoring 2 patients showed pR, and 1 – complete response (CR). In 100 %of cases, there was a decrease in limb weakness, an increase in the mobility. On the 100<sup>th</sup> day of auto‑HSCT hematologic response was deepened to CR in 2 cases, 2 patients retained pR, at long‑term follow‑up – 3 CR and 1 pR. vascular endothelial growth factor response: 2 CR, 1 pR, in 1 case – an increase in marker concentration by 17.5 g / L from the upper limit of normal. On the 100<sup>th</sup> day of auto‑HSCT and at long‑term follow‑up (median 25.5 months) all patients showed further improvement of neurologic status on objective examination and electroneuromyography.</p><p><bold>   Conclusion</bold>. Auto‑HSCT provides high frequency of hematologic response, significantly improvement neurologic status and restoration of patients’ working capacity at long‑term follow‑up. The results of clinical studies, literature data, as well as the results of own observations confirm the efficacy of auto‑HSCT when this method is included into the program therapy of somatically safe young patients with pOEMS‑syndrome.</p></abstract><trans-abstract xml:lang="ru"><p><bold>   Введение. </bold>POEMS‑синдром – редкое лимфопролиферативное заболевание, сопровождаемое прогрессирующей полинейропатией, являющейся ведущей причиной ухудшения качества жизни и смерти больных. У молодых пациентов с сохранным соматическим статусом рассматривается включение в программную терапию аутологичной трансплантации гемопоэтических стволовых клеток (ауто‑ТГСк) для достижения длительного глубокого гематологического ответа и предотвращения инвалидизации. Данные крупных исследований об эффективности ауто‑ТГСк в терапии таких больных отсутствуют. Отдаленные результаты наблюдений за пациентами, получившими ауто‑ТГСк в качестве консолидирующего этапа терапии, позволяют улучшить представление об эффективности включения высокодозного химиотерапевтического воздействия в программное лечение.</p><p><bold>   Цель исследования</bold> – оценить эффективность ауто‑ТГСк в программном лечении пациентов с pOEMS‑синдромом.</p><p> <bold>  Материалы и методы. </bold>Ретроспективно проанализированы медицинские карты 687 пациентов с плазмоклеточными опухолями за 22‑летний период (с 2001 по 2023 гг.). В ретроспективное одноцентровое исследование включены 4 пациента с pOEMS‑синдромом, получивших ауто‑ТГСк.</p><p><bold>   Результаты. </bold>После индукционной терапии в 100 % случаев достигнута частичная гематологическая ремиссия (ЧР). По данным мониторинга содержания фактора роста эндотелия сосудов у 2 пациентов выявлена ЧР, еще у 1 – полная ремиссия (ПР). В 100 % случаев отмечались уменьшение слабости в конечностях, увеличение степени подвижности. На 100‑й день после ауто‑ТГСК гематологический ответ углублен до ПР в 2 случаях, у 2 больных сохранялась ЧР; при длительном наблюдении – 3 пр и 1 ЧР. Ответ по фактору роста эндотелия сосудов: 2 пр, 1 ЧР, в 1 случае – нарастание концентрации маркера на 17,5 г / л от верхней границы нормы. На 100‑й день после ауто‑ТГСК и при длительном наблюдении (медиана 25,5 мес) у всех больных отмечалось дальнейшее улучшение неврологического статуса при объективном исследовании и по результатам электронейромиографии.</p><p><bold>   Заключение.</bold> Ауто‑ТГСК обеспечивает достижение не только высокой частоты гематологического ответа, но и значительное улучшение неврологического статуса, восстановление трудоспособности больных при длительном наблюдении. Результаты клинических исследований, данные литературы, а также собственных наблюдений подтверждают эффективность ауто‑ТГСК при включении данного метода в программную терапию соматически сохранных молодых пациентов с POEMS‑синдромом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pOEMS‑syndrome</kwd><kwd>autologous hematopoietic stem cell transplantation</kwd><kwd>demyelinating polyneuropathy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>pOEMS‑синдром</kwd><kwd>аутологичная трансплантация гемопоэтических стволовых клеток</kwd><kwd>демиелинизирующая полинейропатия</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was performed without external funding</funding-statement><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Dispenzieri A.
