Рецидивы первичной медиастинальной В-крупноклеточной лимфомы (ПМВКЛ) с поражением центральной нервной системы (ЦНС) представляют собой, как правило, некурабельную ситуацию. Тактика терапии больных ПМВКЛ с рецидивом в ЦНС не определена.</p></sec><sec><title>   Цель</title><p>   Цель: представить клинические наблюдения лечения рецидивов ПМВКЛ с поражением ЦНС с применением протокола «R-PML-CNS-2022».</p></sec><sec><title>   Основные сведения</title><p>   Основные сведения. Представлены два клинических наблюдения больных с рецидивами ПМВКЛ с поражением ЦНС. В обоих случаях в качестве противорецидивного лечения был применен протокол «R-PML-CNS-2022» и была достигнута полная ремиссия заболевания. В первом случае в течение 6 мес. после ауто-ТГСК проводили поддерживающую терапию пембролизумабом. Полная ремиссия заболевания сохраняется в течение 15 мес. Во втором наблюдении была также начата поддерживающая терапия пембролизумабом, однако в связи с развитием аутоиммунных осложнений после 2 циклов лечение было прекращено. Полная ремиссия заболевания сохраняется в течение 13 мес.</p></sec><sec><title>   Заключение</title><p>   Заключение: разработка новой стратегии терапии рецидивов ПМВКЛ с поражением ЦНС по протоколу «R-PML–CNS-2022» является потенциально излечивающим подходом в этой группе больных.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Introduction</title><p>   Introduction. Relapses of primary mediastinal large B-cell lymphoma (PMBСL) with involvement of the central nervous system (CNS) are usually incurable. Therapy tactics in patients with PMBCL with relapse in the CNS have not been defined.</p></sec><sec><title>   Aim</title><p>   Aim: to present clinical observations of the treatment of relapses of PMBCL with CNS involvement using the “R-PML-CNS-2022” protocol.</p></sec><sec><title>   Main findings</title><p>   Main findings. Two clinical observations of patients with relapses of PMBCL with involvement of the CNS are presented. In both cases, the “R-PML—CNS-2022” protocol was used as a second-line treatment, and a complete remission of the disease was achieved. In the first case, within 6 months after auto-HCT, maintenance therapy with pembrolizumab was performed. Complete remission of the disease continues for 15 months. In the second observation, maintenance therapy with pembrolizumab was also started, however, due to the development of autoimmune complications after 2 cycles, treatment was discontinued. Complete remission of the disease continues for 13 months.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. The development of a new strategy for the treatment of relapses of PMLCL with CNS lesion according to the “R-PML—CNS-2022” protocol is a potentially curative approach in this group of patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>первичная медиастинальная В- крупноклеточная лимфома</kwd><kwd>рецидив</kwd><kwd>ЦНС</kwd><kwd>ниволумаб</kwd><kwd>леналидомид</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary mediastinal large B-cell lymphoma</kwd><kwd>CNS recurrence</kwd><kwd>nivolumab</kwd><kwd>lenalidomide</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело финансовой поддержки</funding-statement><funding-statement xml:lang="en">The study had no sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Yu Y., Tu M.
