B1-lymphocytes predominantly secrete IgM, which plays an important role in the induction of tumor cell apoptosis. Splenec tomy for the purpose of adequate lymph node dissection in gastric cancer causes marked and prolonged immunological disorders. It primarily affects the B1a-lymphocyte subpopulation, which provides a thymus-independent immune response.</p><p><bold>Objective. </bold>To study the features of the B-cell component of immunity in patients with gastric cancer.</p><p><bold>Materials and methods. </bold>The subpopulation composition of B-lymphocytes of peripheral blood of gastric cancer patients undergoing sur gical treatment using flow cytometry (Facs Can, Lysys II and FacsCanto II programs, Facs Diva program) was analyzed. Cells were stained simultaneously with three monoclonal antibodies labeled with different fluorochromes.</p><p><bold>Results. </bold>The data obtained demonstrate a violation of the composition of B-cell subpopulations. In the group of patients with standard D2 lymph node dissection and splenectomy at the preoperative stage and three months after surgery, a significant correlation was found between the relative number of B lymphocytes (p = 0.018), CD5 + B lymphocytes (p = 0.012) and the number of CD19 + CD38 + cells (p = 0.035). In addition, after surgical treatment, the percentage of CD5 + B-lymphocytes increased significantly from 12.9 to 21.8 %, while the total number of CD19 + lymphocytes and CD19 + CD21 + cells decreased.</p><bold>Conclusion</bold>. In patients of the experimental group, a decrease in antibody production, weakening of both general and antitumor immunity can be observed.</abstract><trans-abstract xml:lang="ru"><p/><p><bold>Введение. </bold>В1-лимфоциты – субпопуляция В-клеток, на долю которой в селезенке приходится 5 % от общего числа В-клеток. В1-лимфоциты секретируют преимущественно IgM, который играет важную роль в индукции апоптоза опухолевых клеток. Спленэктомия с целью адекватной лимфодиссекции при раке желудка вызывает выраженные и длительные иммунологические нарушения. Это в первую очередь затрагивает субпопуляцию В1а-лимфоцитов, которая обеспечивает тимуснезависимый иммунный ответ.</p><p><bold>Цель исследования – </bold>изучить особенности В-клеточного звена иммунитета у больных раком желудка<bold>. </bold></p><p><bold>Материалы и методы. </bold>Проанализирован субпопуляционный состав В-лимфоцитов периферической крови больных раком желудка, подвергшихся хирургическому лечению методом проточной цитометрии (Facs Can, программа Lysys II и FacsCanto II, программа Facs Diva). Клетки окрашивались одномоментно тремя моноклональными антителами, меченными различны ми флуорохромами<bold>. </bold></p><p><bold>Результаты. </bold>Полученные данные демонстрируют нарушение состава субпопуляций В-клеток. В группе больных со стан дартной D2-лимфодиссекцией и спленэктомией на дооперационном этапе и спустя 3 мес после операции выявлена достовер ная корреляция между относительным количеством В-лимфоцитов (p = 0,018), CD5+В-лимфоцитов (p = 0,012) и количеством CD19+CD38+-клеток (p = 0,035). Кроме того, после хирургического лечения значительно возрос процент CD5+В-лимфоци тов – с 12,9 до 21,8 %, тогда как суммарное количество CD19+ лимфоцитов и CD19+СD21+ клеток снижалось.</p><bold>Заключение. </bold>У больных опытной группы может наблюдаться снижение антителoпродукции, ослабление как общего, так и противоопухолевого иммунитета.</trans-abstract><kwd-group xml:lang="en"><kwd>B-lymphocytes</kwd><kwd>thymus-independent antigens</kwd><kwd>humoral immunity</kwd><kwd>gastric cancer</kwd><kwd>splenectomy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>B-лимфоциты</kwd><kwd>тимуснезависимые антигены</kwd><kwd>гуморальный иммунитет</kwd><kwd>рак желудка</kwd><kwd>спленэктомия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
