Поскольку роль лимфоцитарной инфильтрации в течении и прогнозе РП остается дискуссионной, целью исследования явилась разработка прогностического алгоритма оценки риска прогрессирования плоскоклеточного рака пищевода на основании изучения показателей его лимфоцитарного микроокружения.</p><sec><title>Материал и методы</title><p>Материал и методы. У 40 больных РП во время операции брали фрагмент опухоли, который гомогенизировали и методом проточной цитофлюориметрии определяли субпопуляции лимфоцитов (Т-В-NK, T-reg). Прогностический алгоритм расчета риска прогрессирования РП в течение 3 лет после операции был разработан методом дискриминантного анализа c вычислением трех функций – F0 , F6–12, F12–24, соответствующих заключениям об отсутствии риска прогрессирования РП в течение 3 лет (F0 ); о высоком риске прогрессирования в течение 6–12 мес (F6–12); о высоком риске прогрессирования заболевания в течение 12–24 мес (F12–24) после операции.</p></sec><sec><title>Результаты</title><p>Результаты. Показано, что наибольшей дискриминантной мощностью, позволяющей считать различия статистически значимыми, обладают только два показателя: количество CD3+CD4+ и T-reg клеток в опухоли. При разделении больных РП в зависимости от сроков прогнозируемого прогрессирования заболевания были рассчитаны коэффициенты и определены математические выражения для трех дискриминантных функций (F0 , F6–12, F12–24), организованные в модель. Коэффициент F, рассчитанный для каждого больного и представленный в разработанном нами индивидуальном автоматизированном окне в программе Excel, позволил прогнозировать риск прогрессирования рака пищевода через 6–12, 12–24 мес после операции или судить об отсутствии прогрессирования в течение 3 лет после операции.</p></sec><sec><title>Заключение</title><p>Заключение. В прогрессировании РП после операции, вероятно, играет роль лимфоцитарное микроокружение, а именно субпопуляции CD3+CD4+ и T-reg клеток, определение и включение которых в прогностический алгоритм может стать важной частью персонализированного подхода при лечении больных раком пищевода. </p></sec></abstract><trans-abstract xml:lang="en"><p>The development of laboratory criteria for predicting esophageal cancer (EC) prognosis is of great importance due to the need to achieve personalized approach to cancer treatment. Since the role of lymphocytic infiltration in EC remains controversial, our goal was to develop a prognostic algorithm for estimating the risk of esophageal squamous cell carcinoma progression, considering its lymphocytic microenvironment.</p><sec><title>Material and Methods</title><p>Material and Methods. Tumor tissues were obtained from 40 EC patients during surgery; the tissues were homogenized, and lymphocyte subsets (Т-В-NK, T-reg) were determined by flow cytometry. A prognostic algorithm for calculating the risk of EC progression within 3 years was developed using discriminant analysis with the calculation of the three F functions: F0 , F6–12, F12–24, corresponding to the absence of the risk of EC progression during 3 years (F0 ); a high risk of EC progression during 6–12 months (F6–12); a high risk of EC progression during 12–24 months (F12–24) after surgery.</p></sec><sec><title>Results</title><p>Results. Only two factors showed the highest discriminant power, allowing us to consider the differences as statistically significant – CD3+CD4+ and T-reg cells in tumors. When dividing EC patients into groups based on the prediction of time to disease progression, coefficients were calculated and mathematical functions were determined for three discriminant functions (F0 , F6–12, F12–24) organized into a model. The F coefficient calculated for each patient allowed us to predict the risk of EC progression 6–12 and 12–24 months after surgery or the absence of disease progression within 3 years after surgery.</p></sec><sec><title>Conclusions</title><p>Conclusions. The development of EC progression after surgery is apparently influenced by the lymphocytic microenvironment, predominantly by CD3+CD4+ and T-regs; their determination and inclusion in the prognostic algorithm can be important for personalized approach to the treatment of EC patients. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак пищевода</kwd><kwd>прогнозирование</kwd><kwd>лимфоциты опухоли</kwd><kwd>дискриминантный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>esophageal cancer</kwd><kwd>prognosis</kwd><kwd>tumor lymphocytes</kwd><kwd>discriminant analysis</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">Murata A., Baba Y., Watanabe M., Shigaki H., Miyake K., Karashima R., Imamura Y., Ida S., Ishimoto T., Iwagami S., Sakamoto Y., Miyamoto Y., Yoshida N., Baba H. p53 immunohistochemical expression and patient prognosis in esophageal squamous cell carcinoma.
