A detailed analysis of a large cohort of patients with relapsed FL, including detailed clinical, laboratory, morphoimmunohistochemical, and molecular genetic characteristics, the treatments administered at onset and during relapse, as well as the identification of factors correlating with the risk of early progression, is of great scientific and practical interest. This is the focus of this study. Our results will be aimed at optimizing treatment and improving the prognosis of FL patients in Russia who have received second-line therapy.</p> <p><bold>Aim.</bold> To describe changes in the therapeutic landscape of first-line FL therapy from 2001 to 2025 for patients receiving treatment at the National Medical Research Center for Hematology; to analyze the effectiveness of the therapeutic protocols used; to study cases of treatment resistance and identify significant factors influencing the prognosis of the disease; as well as to determine outcomes for patients with the first early relapse of nodal FL.</p> <p><bold>Materials and methods.</bold> A retrospective and prospective study conducted from 2001 to 2025 at the National Medical Research Center of Hematology (Moscow) included 445 patients with newly diagnosed FL of cytological types 1–2 and 3A (World Health Organization, 2017). The median follow-up was 95 (1–251) months. All patients were treated according to the criteria of the Groupe d’Etude des Lymphomes Folliculaires. All patients included in the study were divided into two groups: those who received initial treatment between 2001 and 2022 (the historical control group; <italic>n</italic> = 374) and those who received initial treatment between 2022 and 2025 according to the new FL-2022 risk-based differentiated treatment protocol for patients with nodal FL (<italic>n</italic> = 71). Data for the two groups were analyzed separately.</p> <p><bold>Results.</bold> With a median follow-up of 98 (1–251) months, the 2-year, 5-year, and 10-year overall survival of 374 patients from the historical control group (2001–2022) were 93, 90, and 85 %, respectively; 2-year, 5-year, and 10-year event-free survival were 82, 71, and 55 %, respectively. With high-dose chemotherapy, compared with standard regimens, the proportion of progressions / relapses was significantly lower (26 % <italic>versus</italic> 40 %; <italic>p</italic> = 0.01), but if events occurred, they were predominantly early (72 % <italic>versus</italic> 58 %; <italic>p</italic> = 0.2). According to the results of multivariate analysis, independent prognostic risk factors for disease progression within 24 months after the start of therapy (POD24) were identified: absence of <italic>BCL2</italic> gene rearrangement (odds ratio 3.52 (1.89–6.55); <italic>p</italic> &lt;0.0001) and 3A cytological type (odds ratio 3.8 (1.61–0.16); <italic>p</italic> = 0.0033). During second-line therapy in the first early relapse / progression after R-B (rituximab + bendamustine), R-CHOP (rituximab + cyclophosphamide + doxorubicin + vincristine + prednisolone) and autologous hematopoietic stem cell transplantation, complete remission was achieved in only 38 % of patients, and after R-DHAP it was not achieved in any case. With therapy according to the FL-2022 protocol (2022–2025), with a median follow-up of 23 months, 2-year overall survival was 100 %, 2-year event-free survival was 97 %. Second-line therapy was required in only 6 % of patients.</p> <p><bold>Conclusion.</bold> The development of early relapse / progression has a critical impact on the survival prognosis of FL patients. The use of a differentiated treatment protocol for patients with nodal FL (FL-2022), based on clinical, morphological, immunohistochemical, and genetic prognostic factors, has significantly improved treatment outcomes and reduced the risk of POD24. When FL first relapses, there is no uniform treatment standard, and the regimens used vary greatly. Treatment outcomes in the first relapse remain modest, especially for the high-risk POD24 group, necessitating a change in the treatment paradigm for this patient group.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> В российской клинической практике отсутствует систематизированная информация о пациентах с рецидивами фолликулярной лимфомы (ФЛ) после 1-й линии терапии; представлены единичные данные, отражающие частоту ранних и поздних рецидивов в отечественной популяции, схемы терапии 1-й линии, применявшиеся у этих пациентов, динамику ответа на лечение и сроки возникновения рецидива, режимы терапии 2-й линии. Подробный анализ данных большой когорты пациентов с рецидивами ФЛ, включая детализацию клинико-лабораторных, морфоиммуногистохимических, молекулярно-генетических характеристик, проведенных линий терапии в дебюте и при рецидиве, а также обнаружение факторов, коррелирующих с рисками раннего прогрессирования, представляют большой научно-практический интерес. Полученные результаты лягут в основу оптимизации лечения и улучшения прогноза пациентов с ФЛ в России, получающих 2-ю линию терапии.</p> <p><bold>Цель исследования</bold> – описать изменения терапевтического ландшафта 1-й линии терапии ФЛ с 2001 по 2025 г. для пациентов, получающих лечение в Национальном медицинском исследовательском центре гематологии; проанализировать результативность применяемых терапевтических протоколов; изучить случаи резистентности к лечению и определить значимые факторы, влияющие на прогноз заболевания, а также исходы для клинической группы пациентов с 1-м ранним рецидивом нодальной ФЛ.</p> <p><bold>Материалы и методы.</bold> В ретроспективно-проспективное исследование, проведенное c 2001 по 2025 г. в Национальном медицинском исследовательском центре гематологии, включены 445 пациентов с впервые диагностированной ФЛ цитологических типов 1–3А (Всемирная организация здравоохранения, 2017). Медиана времени наблюдения за больными составила 95 (1–251) мес. Всем пациентам показана терапия в соответствии с критериями Groupe d’Etude des Lymphomes Folliculaires. Все пациенты, включенные в исследование, разделены на 2 группы: получившие инициальное лечение в период 2001–2022 гг. (группа исторического контроля; <italic>n</italic> = 374) и в 2022–2025 гг. согласно новому протоколу дифференцированной терапии больных нодальной ФЛ с учетом факторов риска FL-2022 (<italic>n</italic> = 71). Данные для 2 групп анализировали раздельно.</p> <p><bold>Результаты.</bold> При медиане времени наблюдения 98 (1–251) мес 2-, 5- и 10-летняя общая выживаемость 374 пациентов группы исторического контроля (2001–2022) составила 93, 90, 85 %; бессобытийная выживаемость – 82, 71, 55 % соответственно. При проведении высокодозной химиотерапии по сравнению со стандартными режимами доля прогрессирований / рецидивов оказалась существенно меньше (26 % против 40 %; <italic>p</italic> = 0,01), но если события случались, то они были преимущественно ранними (72 % против 58 %; <italic>p</italic> = 0,2). По результатам многофакторного анализа определены независимые прогностические факторы риска прогрессирования заболевания в течение 24 мес после начала терапии (POD24): отсутствие реаранжировки гена <italic>BCL2</italic> (отношение шансов 3,52 (1,89–6,55); <italic>p</italic> &lt;0,0001) и цитологический тип 3А (отношение шансов 3,8 (1,61–0,16); <italic>p</italic> = 0,0033). При проведении 2-й линии терапии при 1-м раннем рецидиве / прогрессировании после R-B (ритуксимаб + бендамустин), R-CHOP (ритуксимаб + циклофосфамид + доксорубицин + винкристин + преднизолон) и трансплантации аутологичных гемопоэтических стволовых клеток полная ремиссия достигнута лишь у 38 % пациентов, а после R-DHAP – не достигнута ни в одном случае. При терапии по протоколу FL-2022 (2022–2025) при медиане времени наблюдения 23 мес 2-летняя общая выживаемость составила 100 %, бессобытийная – 97 %. Вторая линия терапии потребовалась лишь 6 % пациентам.</p> <p><bold>Заключение.</bold> Развитие раннего рецидива / прогрессирования оказывает критическое влияние на прогноз выживаемости пациентов с ФЛ. Внедрение протокола дифференцированной терапии больных нодальной ФЛ (FL-2022), основанного на клинико-морфоиммуногистохимических и генетических факторах прогноза, позволило существенно улучшить результаты лечения и снизить риски POD24. При развитии 1-го рецидива ФЛ отсутствует единый стандарт лечения и наблюдается чрезвычайная вариативность применяемых схем. Исходы терапии при 1-м рецидиве остаются скромными, особенно для пациентов группы высокого риска POD24, что диктует необходимость изменения парадигмы лечения этой группы пациентов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>follicular lymphoma</kwd><kwd>prognosis</kwd><kwd>relapse</kwd><kwd>POD24</kwd><kwd>BCL2 gene rearrangement</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фолликулярная лимфома</kwd><kwd>прогноз</kwd><kwd>рецидив</kwd><kwd>POD24</kwd><kwd>реаранжировка гена BCL2</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>Jacobsen E.
