Изучить экспрессию иммунофенотипических маркерных молекул на В-лимфоцитах больных хроническим лимфолейкозом на этапах иммунохимиотерапии при мониторинге минимальной остаточной болезни.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы. Обследованы 20 больных ХЛЛ, которым в период 2019–2022 гг. проведено 6 курсов иммунохимиотерапии (ИХТ) в режиме RB/FCR в НМИЦ онкологии г. Ростова-на-Дону. До лечения, после 3, 6 курсов ИХТ выполнялось иммунофенотипирование костного мозга методом проточной цитофлюориметрии. Данные оценены в Statistica 13.0.</p></sec><sec><title>Результаты</title><p>Результаты. До лечения в зависимости от экспрессии прогностических маркеров (CD38, ZAP‑70, CD11c, CD25, FMC7) выделены 3 группы больных. I (2 чел.) – без экспрессии CD38, ZAP‑70, CD11c, CD25, FMC7 на опухолевых В-лимфоцитах. II (14 чел.) – с вариабельной экспрессией CD25, CD38 (0,4–47,6 % и 0,0–57,5 %, соответственно), отсутствием экспрессии ZAP‑70, CD11c, FMC7. III (4 чел.) – с высокой экспрессией CD38 (57,5–69,2 %), ZAP‑70 (36,6–48,3 %), CD11c (20,0–96,5 %), CD25 (64,9–92,7 %), FMC7 (13,6–88,6 %). После 3 курса ИХТ минимальная остаточная болезнь (МОБ): в I группе 0 %, во II-й 0,48 ± 0,13 %, в III-й 33,5 ± 7,84 %. После 6 курса ИХТ МОБ: в I группе 0 %, во II-й 0,42 ± 0,09 %, в III-й 33,2 ± 8,07 %. Экспрессия иммунофенотипических маркеров в II, III группах без изменений после 3,6 курсов ИХТ. Согласно критериям оценки ответа на терапию (IWCLL, 2018 г.) у пациентов I, II групп после 6 курса ИХТ полная ремиссия, у 3‑х пациентов III группы частичная ремиссия, у 1 больного стабилизация процесса. Получены предварительные данные, указывающие на то, что отсутствие или повышенный уровень экспрессии CD38, CD25, ZAP‑70, CD11c, FMC7 на В-лимфоцитах больных ХЛЛ до лечения могут предопределять гематологический ответ на терапию по схемам RB/FCR.</p></sec><sec><title>Заключение</title><p>Заключение. Исходно повышенная экспрессия одновременно всех прогностических антигенов: CD38, CD25, ZAP‑70, CD11c, FMC7 на опухолевой популяции В-лимфоцитов больных ХЛЛ ассоциируется с неудовлетворительным ответом на лечение, что представляется перспективным с точки зрения изучения влияния анализируемых маркерных молекул на достижение гематологического ответа на этапах иммунохимиотерапии. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. To study the expression of immunophenotypic marker molecules on B-lymphocytes of patients with chronic lymphocytic leukemia at the stages of immunochemotherapy while monitoring minimal residual disease.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. 20 patients with CLL were examined, who in the period 2019–2022 underwent 6 courses of immunochemotherapy (ICT) in the RB/FCR mode at the National Medical Research Centre for Oncology, Rostov-on-Don. Before, after 3, 6 courses of ICT, bone marrow immunophenotyping was performed by flow cytometry. The data is evaluated in Statistica 13.0.</p></sec><sec><title>Results</title><p>Results. Before treatment, 3 groups of patients were identified depending on the expression of prognostic markers (CD38, ZAP‑70, CD11c, CD25, FMC7). I (2 people) – without expression of CD38, ZAP‑70, CD11c, CD25, FMC7 on tumor B-lymphocytes. II (14 people) – with variable expression of CD25, CD38 (0.4–47.6 % and 0.0–57.5 %, respectively), lack of expression of ZAP‑70, CD11c, FMC7. III (4 people)– with high expression of CD38 (57.5–69.2 %), ZAP‑70 (36.6–48.3 %), CD11c (20.0–96.5 %), CD25 (64.9–92.7 %), FMC7 (13.6–88.6 %). After the 3rd course of ICT, the minimum residual disease (MRD): 0 % in group I, 0.48 ±  0.13 % in group II, 33.5 ± 7.84 % in group III. After the 6th course of ICT MRD: 0 % in group I, 0.42 ± 0.09 % in group II, 33.2 ± 8.07 % in group III. The expression of immunophenotypic markers in groups II and III remained unchanged after 3, 6 courses of ICT. According to the criteria for assessing the response to therapy (IWCLL, 2018), patients of groups I, II after the 6th course of ICT have complete remission, 3 patients of group III have partial remission, 1 patient has stabilization of the process. Preliminary data have been obtained indicating that the absence or increased expression of CD38, CD25, ZAP‑70, CD11c, FMC7 on B-lymphocytes of CLL patients before treatment may predetermine the hematological response to therapy according to RB/FCR regimens.</p></sec><sec><title>Conclusion</title><p>Conclusion. Initially, increased expression of all prognostic antigens simultaneously: CD38, CD25, ZAP‑70, CD11c, FMC7 on the tumor population of B-lymphocytes in patients with CLL is associated with an unsatisfactory response to treatment, which seems promising from the point of view of studying the effect of the analyzed marker molecules on achieving a hematological response at the stages of immunochemotherapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический лимфолейкоз</kwd><kwd>проточная цитометрия</kwd><kwd>минимальная остаточная болезнь</kwd><kwd>иммунофенотипические маркеры</kwd><kwd>иммунохимиотерапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic lymphocytic leukemia</kwd><kwd>flow cytometry</kwd><kwd>minimal residual disease</kwd><kwd>immunophenotypic markers</kwd><kwd>immunochemotherapy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Войцеховский В.
