Несмотря на прогресс в химиотерапии и иммунотерапии, отдаленные результаты лечения не всегда удовлетворительны. Для стратификации риска и оценки ответа на терапию в качестве потенциальных биомаркеров все больше внимания уделяется изучению количественных показателей (метрик), получаемых на основе данных позитронно-эмиссионной томографии с 18F-фтордезоксиглюкозой (18F-ФДГ ПЭТ/КТ).</p></sec><sec><title>Цель</title><p>Цель: Оценить прогностическую значимость объемно-метаболических показателей 18F-ФДГ ПЭТ/КТ у пациентов с диффузной В-крупноклеточной лимфомой (ДВКЛЛ) и сравнить эффективность различных методов сегментации опухолевой нагрузки.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: В исследование включены данные 150 пациентов с ДВКЛЛ, получавших лечение по схеме R-CHOP в период 2018–2024 гг. Всем пациентам выполнена 18F-ФДГ ПЭТ/КТ до начала терапии. Метаболический объем опухоли (MTV) и общий гликолитический объем (TLG) рассчитывались с использованием двух порогов сегментации: фиксированного (SUV &gt; 4) и относительного (41 % от SUVmax). Для анализа прогностической значимости применялись ROC-анализ, методы машинного обучения (yGBoost) и оценка выживаемости без прогрессирования (ВБП).</p></sec><sec><title>Результаты</title><p>Результаты: Все исследуемые показатели (MTV, TLG, их нормализованные аналоги) продемонстрировали сопоставимую прогностическую точность (AUC 0,766–0,790). Наибольшую значимость показал нормализованный по массе тела MTV при пороге SUV &gt; 4 (sMTV), который позволил стратифицировать пациентов на группы низкого ( &lt; 3 мл/кг) и высокого риска (≥​​3 мл/кг). 5-летняя ВБП составила 83,3 % и 39,4 % соответственно (p &lt; 0,001). Обсуждение: Традиционные методы, такие как ROC-анализ и тест Делонга, не учитывают взаимодействия, затрудняя выбор ͨлучшейͩ метрики. В настоящем исследовании использование алгоритма yGBoost позволило выделить нормализованный по массе тела об̻̘м, рассчитанный по порогу SUV &gt; 4 (sMTV SUV &gt; 4), как наиболее значимый предиктор.</p></sec><sec><title>Заключение</title><p>Заключение: Нормализованный по массе тела метаболический объем опухоли является наиболее информативным прогностическим маркером у пациентов с ДВКЛЛ, что подтверждает его потенциальную клиническую ценность для персонализированного подхода к лечению.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction: Diffuse large B-cell lymphoma (DLBCL) is the most common form of aggressive non-Hodgkin͛s lymphoma, accounting for up to 40 % of all cases. Despite significant advances in chemotherapy and immunotherapy, long-term treatment outcomes are not always satisfactory. In recent years, quantitative metrics derived from 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET/CT), such as metabolic tumor volume (MTV), total glycolytic tumor volume (TLG), and others, have received increasing attention as potential biomarkers for risk stratification and assessment of treatment response.</p></sec><sec><title>Purpose</title><p>Purpose: To evaluate the prognostic value of 18F-FDG PET/CT volumetric-metabolic parameters in patients with diffuse large B-cell lymphoma (DLBCL) and to compare the effectiveness of different tumor burden segmentation methods.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: Data from 150 DLBCL patients treated with R-CHOP regimen between 2018 and 2024 were included. All patients underwent 18F-FDG PET/CT prior to therapy initiation. Metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were calculated using two segmentation thresholds: a fixed threshold (SUV &gt; 4) and a relative threshold (41 % of SUVmax). Receiver operating characteristic (ROC) analysis, machine learning techniques (yGBoost), and progression-free survival (PFS) assessment were used to evaluate prognostic significance.</p></sec><sec><title>Results</title><p>Results: All investigated parameters (MTV, TLG, and their normalized counterparts) demonstrated comparable prognostic accuracy (AUC 0.766–0.790). The body weight-normalized MTV using the SUV &gt; 4 threshold (sMTV) showed the highest prognostic significance, enabling patient stratification into low-risk (&lt; 3 mL/kg) and high-risk (≥​​3 mL/kg) groups. The 5-year PFS rates were 83.3 % and 39.4 %, respectively (p &lt; 0.001).</p></sec><sec><title>Discussion</title><p>Discussion: Traditional methods such as ROC analysis and the DeLong test do not account for interactions, making it difficult to select the best metric. In this study, the yGBoost algorithm identified the weight-normalized volume, calculated using the SUV &gt; 4 threshold (sMTV SUV &gt; 4), as the most significant predictor.</p></sec><sec><title>Conclusion</title><p>Conclusion: Body weight-normalized metabolic tumor volume is the most informative prognostic marker in DLBCL patients, highlighting its potential clinical value for personalized treatment approaches.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>18F-ФДГ ПˑТ/КТ</kwd><kwd>диффузная В-крупноклеточная лимфома</kwd><kwd>метаболический об̻ем опухоли</kwd><kwd>общий гликолитический объем</kwd><kwd>методы сегментации</kwd><kwd>машинное обучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>18F-FDG PET/CT</kwd><kwd>diffuse large B-cell lymphoma</kwd><kwd>metabolic tumor volume</kwd><kwd>total lesion glycolysis</kwd><kwd>segmentation methods</kwd><kwd>machine learning</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки.</funding-statement><funding-statement xml:lang="en">The study had no sponsorship.</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">Sehn LH, Salles G.
