To evaluate the efficacy and safety of the BR regimen containing bendamustine in patients with chronic lymphocytic leukemia (CLL) who have not previously received specific therapy. Subjects and methods. The results of the Russian prospective observational multicenter study BEN-001 (2012—2015) covering 196 CLL patients from 34 centers of the Russian Federation were analyzed. The diagnosis was confirmed by the results of peripheral blood lymphocyte immunophenotyping. A centralized approach was employed to make IGHV gene mutational status analysis, FISH examination, and minimal residual disease according to standardized methods. Quality-of-life (QOL) indicators were estimated using the EQ-5D and FACT-Leu questionnaires. Survival rates were calculated applying by the Kaplan-Meier method. Results. The patients’ median age was 61 years. 41% of patients had a decline in estimated creatinine clearance less than 70 ml/min/1.73 m2. The combination of bendamustine and rituximab could achieve a common response in 83.2% of the patients, including complete remission in 59.7%. Eradication of minimal residual disease was achieved in 23 (27.4%) of 84 patients. Two-year progression-free survival rates were 85.9%. The QOL indicators were noted to be improved during the treatment. Conclusion. The investigation shows the good tolerability of bendamustine when it is used in clinical practice. Due to the high cost of new drugs (ibrutinib, obinutuzumab, ofatumumab, etc.) and toxicity of the FCR regimen, the combination including bendamustine can be the best first-line therapy option for all CLL patients, regardless of their age and comorbidity.</p></abstract><trans-abstract xml:lang="ru"><p>Резюме Цель исследования. Оценка эффективности и безопасности режима BR, содержащего бендамустин, у пациентов с хроническим лимфолейкозом (ХЛЛ), ранее не получавших специфическую терапию. Материалы и методы. Проанализированы результаты российского проспективного наблюдательного многоцентрового исследования BEN-001 (2012—2015 гг.), в котором приняли участие 196 больных ХЛЛ из 34 центров Российской Федерации. Диагноз подтверждали результатами иммунофенотипирования лимфоцитов периферической крови. Анализ мутационного статуса генов IGHV, FISH-исследование и оценку минимальной остаточной болезни проводили централизовано по стандартизированным методикам. Показатели качества жизни (КЖ) оценивали с помощью опросников EQ-5D и FACT-Leu. Выживаемость рассчитывали по методу Каплана—Майера. Результаты. Медиана возраста пациентов составила 61 год. У 41% больных наблюдалось снижение расчетного клиренса креатинина менее 70 мл/мин/1,73 м2. Комбинация бендамустина и ритуксимаба позволила достичь общий ответ у 83,2% пациентов, в том числе полную ремиссию у 59,7%. Эрадикация минимальной остаточной болезни достигнута у 23 (27,4%) из 84 больных. Двухлетняя выживаемость без прогрессирования составила 85,9%. На фоне лечения отмечалось улучшение показателей КЖ. Заключение. Результаты исследования показывают хорошую переносимость бендамустина при его использовании в клинической практике. В связи с высокой стоимостью новых препаратов (ибрутиниб, обинутузумаб, офатумумаб и др.) и токсичностью режима FCR комбинации с включением бендамустина могут быть оптимальным вариантом терапии первой линии для всех больных ХЛЛ, вне зависимости от возраста и сопутствующей патологии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chronic lymphocytic leukemia</kwd><kwd>BR</kwd><kwd>bendamustine</kwd><kwd>BR</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хронический лимфолейкоз</kwd><kwd>бендамустин</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Chen Q, Jain N, Ayer T, Wierda WG, Flowers CR, O’Brien SM, Keating MJ, Kantarjian HM, Chhatwal J.
