Активное внедрение иммунотерапии в клиническую онкологическую практику позволило значительно улучшить результаты лекарственного лечения опухолей. Это привело к необходимости поиска новых маркеров, с помощью которых можно оценить эффективность проводимой терапии и прогноз заболевания.</p><p>Цель исследования – анализ содержания растворимых форм белков контрольных точек иммунитета sPD-1 и PD-L1 в сыворотке крови больных немелкоклеточным раком легкого и плоскоклеточным раком пищевода, а также их ассоциации с клинико-морфологическими характеристиками заболевания и прогнозом.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включены образцы опухолей от 43 пациентов с немелкоклеточным раком легкого и 21 пациента с плоскоклеточным раком пищевода. Концентрацию sPD-L1 и sPD-1 определяли в сыворотке крови с помощью иммуноферментного анализа. Для определения статистически значимых различий в независимых группах использовали критерий Манна – Уитни. Корреляционный анализ проводили с помощью определения коэффициента ранговой корреляции Спирмена. Анализ общей выживаемости – путем построения кривых дожития по методу Каплана – Мейера и с использованием модели пропорциональных рисков Кокса. Статистически достоверными считались различия при р &lt; 0,05.</p></sec><sec><title>Результаты</title><p>Результаты. Показано, что sPD-1и sPD-L1 обнаруживаются в сыворотке крови как у пациентов с онкологическими заболеваниями, так и здоровых доноров, и их концентрации значимо не отличаются. Показано, что высокая концентрация sPD-L1 в сыворотке крови больных немелкоклеточным раком легкого значимо ассоциирована с поздней стадией заболевания и является независимым неблагоприятным прогностическим фактором. Необходимо отметить, что для пациентов с раком пищевода неблагоприятным прогностическим маркером является высокое содержание растворимой формы рецептора PD-1, а не его лиганда PD-L1, как для рака легкого.</p></sec><sec><title>Выводы</title><p>Выводы. Содержание в сыворотке крови sPD-1и sPD-L1 может иметь различное прогностическое значение для злокачественных опухолей различных нозологий, и необходимость его анализа для клинического применения требует дальнейшего изучения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Implementation of immunotherapy in clinical oncological practice has significantly improved the results of cancer treatment. It resulted in the need for seeking new markers to assess the effectiveness of therapy and the disease prognosis.</p></sec><sec><title>Aim</title><p>Aim. To analyze the content of soluble forms of PD-1 and PD-L1 immune checkpoint proteins in the blood serum of patients with non-small cell lung cancer and esophageal squamous cell carcinoma and their association with clinical and morphological characteristics of the disease and the disease prognosis.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included tumor samples obtained from 43 patients with non-small cell lung cancer and 21 patients with esophageal squamous cell carcinoma. The concentration of sPD-L1 and sPD-1 in the blood serum was determined using enzyme-linked immunosorbent assay (ELISA). The Mann – Whitney test was used to determine statistically significant differences in independent groups. A correlation analysis was performed using the Spearman’s rank correlation coefficient. Overall survival was analyzed by constructing survival curves using the Kaplan – Meier method and a Cox proportional hazards model. The differences were considered statistically significant at p &lt; 0.05.</p></sec><sec><title>Results</title><p>Results. The study showed that sPD-1 and sPD-L1 were found in the blood serum of both cancer patients and healthy donors, and their concentrations did not differ significantly. It was shown that the high concentration of sPD-L1 in the blood serum of patients with non-small cell lung cancer was significantly associated with the late stage of the disease and was an independent unfavorable prognostic factor. It should be noted that for patients with esophageal cancer, an unfavorable prognostic marker was the high concentration of the soluble form of PD-1 protein, and not PD-L1 ligand, as in case of lung cancer.</p></sec><sec><title>Conclusion</title><p>Conclusion. The content of sPD-1 and sPD-L1 in the blood serum can have different prognostic significance for various types of cancer, and further studies are required to confirm their clinical usability.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>sPD-1</kwd><kwd>sPD-L1</kwd><kwd>иммунотерапия</kwd><kwd>немелкоклеточный рак легкого</kwd><kwd>рак пищевода</kwd><kwd>прогноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sPD-1</kwd><kwd>sPD-L1</kwd><kwd>immunotherapy</kwd><kwd>non-small cell lung cancer</kwd><kwd>esophageal cancer</kwd><kwd>prognosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта РФФИ (проект № 20015-004790)</funding-statement><funding-statement xml:lang="en">The study was supported by the RFBR grant (project No. 20-015-004790)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Orme J.J., Enninga E.A.L., Lucien-Matteoni F., Dale H., Burgstaler E., Harrington S.M. et al.
