The problem of establishing reliable prognostic factors that could help identify high- or ultra-high-risk patients is still unresolved. We performed a systematic literature review and meta-analysis of studies investigating the predictive value of baseline metabolic parameters of <sup>18</sup>F-fluorodeoxyglucose (<sup>18</sup>F-FDG) positron emission tomography/computed tomography (PET/CT) in pediatric patients with lymphomas. We systematically searched the following databases: PubMed, Medline, Cochrane Library and Google Scholar. Six retrospective studies (309 patients) evaluating the effect of quantitative parameters derived from baseline PET/CT with <sup>18</sup>F-FDG (maximum standardized uptake value (SUV<sub>max</sub>), tumor metabolic volume (MTV), and total lesion glycolysis (TLG)) on OS and event-free survival (EFS) in children with HL and NHL were included in our analysis. We used the Cochrane ROBINS-I tool to assess the quality of studies; the relative risks (RR) for the studied outcomes were calculated with RevMan software, version 5.3. The overall analysis showed that high MTV was associated with a six-fold increase in the relative mortality risk (RR 6.18 (3.15–12.11), p &lt; 0.001) and a more than 5-fold increase in the risk of relapse/progression (RR 5.68 (3.21–10.07), p &lt; 0.001). High values of TLG were associated with an eight-fold increase in the risk of mortality (RR 8.06 (3.35–19.39), p &lt; 0.001) and worse EFS (RR 5.75 (2.99–11.06), p &lt; 0.001). Our results will enable oncologists to expand existing risk assessment systems and improve their predictive effectiveness by using MTV and TLG parameters.</p></abstract><trans-abstract xml:lang="ru"><p>Пятилетняя общая выживаемость (ОВ) при детских неходжкинских лимфомах (НХЛ) и лимфоме Ходжкина (ЛХ) остается на уровне 85–95%, несмотря на совершенствование схем терапии. На сегодняшний день задача выявления достоверных прогностических факторов, позволяющих идентифицировать пациентов из группы высокого/ультравысокого риска, не решена. Мы провели систематический обзор литературы и метаанализ исследований прогностической ценности инициальных метаболических параметров накопления фтордезоксиглюкозы, меченной <sup>18</sup>F (<sup>18</sup>F-ФДГ), при выполнении позитронно-эмиссионной томографии, совмещенной с компьютерной томографией (ПЭТ/КТ), у педиатрических пациентов с лимфомами. Поиск проводился в базах данных PubMed, Medline, Cochrane Library и Google Scholar. В исследование были включены 6 ретроспективных исследований (n = 309), оценивающих влияние инициальных параметров количественной оценки ПЭТ/КТ с <sup>18</sup>F-ФДГ (максимальное стандартизованное значение поглощения (SUV<sub>max</sub>), метаболический объем опухоли (MTV), общий гликолиз опухоли (TLG)) на ОВ и бессобытийную выживаемость (БСВ) у детей с ЛХ и НХЛ. Мы использовали Кокрановский инструмент ROBINS-I для оценки качества исследований, относительные риски (ОР) для изучаемых исходов были рассчитаны в программном продукте RevMan, версия 5.3. Общий анализ данных показал, что высокий показатель MTV был сопряжен с шестикратным увеличением риска летального исхода (ОР = 6,18 (3,15–12,11), p &lt; 0,001) и увеличением риска рецидива/прогрессирования более чем в 5 раз (ОР = 5,68 (3,21–10,07), p &lt; 0,001). Высокие значения TLG были сопряжены с восьмикратным увеличением риска летального исхода (ОР = 8,06 (3,35–19,39), p &lt; 0,001) и меньшей БСВ (ОР = 5,75 (2,99–11,06), p &lt; 0,001). Полученные результаты позволят врачам-онкологам расширить существующие системы оценки рисков за счет включения параметров MTV и TLG для повышения их прогностической эффективности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>lymphoma</kwd><kwd>children</kwd><kwd>maximum standardized uptake value</kwd><kwd>total lesion glycolysis</kwd><kwd>tumor metabolic volume</kwd><kwd>survival</kwd><kwd>positron emission tomography/computed tomography</kwd><kwd>18F-fluorodeoxyglucose</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лимфома</kwd><kwd>дети</kwd><kwd>максимальное стандартизованное значение поглощения</kwd><kwd>общий гликолиз опухоли</kwd><kwd>метаболический объем опухоли</kwd><kwd>выживаемость</kwd><kwd>позитронно-эмиссионная томография</kwd><kwd>совмещенная с компьютерной томографией</kwd><kwd>фтордезоксиглюкоза, меченная 18F</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Buhtoiarov I.N.
