Coronavirus disease (COVID-19), caused by SARS-CoV-2, presents new challenges to hematologists, highlighting the vulnerability of patients with hematological malignancies, in particular with diffuse large B-cell lymphoma (DLBCL). Identification of hospital mortality risk factors is necessary for subsequent stratification of patients into risk groups, which will allow further risk-based therapy.</p><p><bold>Aim</bold>. To develop a prognostic model and identify risk factors for hospital mortality in patients with DLBCL associated with COVID-19.</p><p><bold>Materials and methods</bold>. The interim retrospective study included 112 patients with an immunohistochemically confirmed diagnosis of DLBCL, coronavirus infection verified based on polymerase chain reaction (PCR) for SARS-CoV-2, and viral pneumonia associated with COVID-19. To determine the risk factors for hospital mortality, a multivariate (logistic regression) statistical analysis was performed. The study end point was a binary variable - the patient vital status (discharged alive or died).</p><p><bold>Results and conclusion</bold>. Of the 112 patients, 24 died. Due to the limited number of patients compared to the number of predictors and to avoid overfitting, a two-stage approach to constructing a predictive model was used. In univariate analysis, statistically significant during hospitalization were the hematological disease status (complete remission/partial remission, progression/relapse, <italic>de novo</italic>), positive PCR result, C-reactive protein level &gt;6 mg/L, platelets &lt;100 thousand/pL, hemoglobin &lt;120 g/L, albumin &lt;35 g/L, lactate dehydrogenase &gt;248 U/L, D-dimer &gt;500 ng/mL and the degree of lung tissue damage according to computed tomography &gt;50 % (grade II and above), respiratory failure I degrees and higher. The final model was constructed by minimizing the Akaike information criterion. The final model included a positive PCR result, stage II respiratory failure, hematologic disease status (relapse/progression), and albumin level at the time of hospital admission.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Коронавирусная инфекция (COVID-19), вызванная SARS-CoV-2, ставит перед гематологами новые вызовы, подчеркивая уязвимость пациентов со злокачественными гематологическими новообразованиями, в частности с диффузной В-крупноклеточной лимфомой (ДВКЛ). Выявление факторов риска внутригоспитальной летальности необходимо для последующей стратификации пациентов на группы риска, что позволит в дальнейшем проведение риск-ориентированной терапии.</p><p><bold>Цель исследования</bold> - разработка прогностической модели и выявление факторов риска внутригоспитальной летальности пациентов с ДВКЛ, сопряженной с COVID-19.</p><p><bold>Материалы и методы</bold>. В промежуточное ретроспективное исследование были включены 112 пациентов с иммуногистохимически подтвержденным диагнозом ДВКЛ, коронавирусной инфекцией, верифицированной на основании полимеразной цепной реакции (ПЦР) на SARS-CoV-2, и вирусной пневмонией, ассоциированной с COVID-19. Для определения факторов риска внутригоспитальной летальности проведен многофакторный (логистическая регрессия) статистический анализ. Конечной точкой исследования явилась бинарная переменная - жизненный статус больного (выписан живым или летальный исход).</p><p><bold>Результаты и заключение</bold>. Из 112 пациентов 24 умерли. Ввиду ограниченного числа пациентов по сравнению с количеством предикторов и с целью избежать переобучения применяли двухэтапный подход построения прогностической модели. в однофакторном анализе статистически значимыми на период госпитализации были статус гематологического заболевания (полная ремиссия/частичная ремиссия, прогрессия/рецидив, <italic>de novo</italic>), положительный результат ПЦР, уровни С-реактивного белка &gt;6 мг/л, тромбоцитов &lt;100 тыс/мкг, гемоглобина &lt;120 г/л, альбумина &lt;35 г/л, лактатдегидрогеназы &gt;248 ЕД/л, D-димера &gt;500 нг/мл и степень поражения ткани легких по данным компьютерной томографии &gt;50 % (II степень и выше), дыхательная недостаточность I степени и выше. финальная модель построена путем минимизации информационного критерия Акаике. В итоговую модель вошли положительный результат ПЦР, дыхательная недостаточность II степени, статус гематологического заболевания (рецидив/прогрессия) и уровень альбумина на момент госпитализации в стационар.</p></trans-abstract><kwd-group xml:lang="en"><kwd>prognostic model</kwd><kwd>hospital mortality</kwd><kwd>diffuse large B-cell lymphoma</kwd><kwd>coronavirus infection</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>прогностическая модель</kwd><kwd>внутригоспитальная летальность</kwd><kwd>диффузная В-крупноклеточная лимфома</kwd><kwd>коронавирусная инфекция</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.
