В группу низкого генетического риска (НГР) вошли 114 пациентов с транслокацией t(12;21)(p13;q22)/ETV6-RUNX1 или высокой гипердиплоидией с отсутствием делеций генов IKZF1, PAX5, ETV6, RB1, BTG1, EBF1, CDKN2A/2B и в псевдоаутосомном регионе PAR1, или с единичными делециями генов ETV6/PAX5/BTG1, или наличием делеций гена ETV6 с одной дополнительной делецией BTG1/PAX5/CDKN2A/B. Всех остальных пациентов (n = 28) относили к группе высокого генетического риска (ВГР). Пациенты ВГР были достоверно старше (p = 0,015), чаще стратифицировались в группу высокого риска протокола ALL-MB-2008 (p = 0,001), имели высокий инициальный лейкоцитоз (p = 0,008), M3-статус костного мозга на 15-й день индукционной терапии (p = 0,002), отсутствие гематологической ремиссии на 36-й день (p = 0,039) по сравнению с группой НГР. Больные группы ВГР имели статистически значимо более низкие бессобытийную выживаемость (БСВ) (0,59 ± 0,11 и 0,88 ± 0,03; p = 0,0008) и общую выживаемость (ОВ) (0,63 ± 0,15 и 0,93 ± 0,02; p = 0,0050), а также более высокую кумулятивную частоту развития рецидива (КЧР) (0,38 ± 0,12 и 0,06 ± 0,02; p &lt; 0,0001) по сравнению с группой НГР. Деление на группы генетического риска сохраняло прогностическое значение и в многофакторном анализе по влиянию на БСВ (относительный риск (ОР) – 2,659; 95 % ДИ 1,047– 6,755; p = 0,040) и КЧР (ОР – 3,864; 95 % ДИ 1,226–12,183; p = 0,021), но не влияло на ОВ (ОР – 1,479; 95 % ДИ 0,356–6,139; p = 0,590). Деление на группы генетического риска утрачивало свою прогностическую роль в группе «другие B-линейные ОЛЛ». Большинство неблагоприятных событий (9 из 10) и рецидивов (8 из 9) у пациентов группы ВГР было выявлено при наличии у них делеций IKZF1. Более того, все 15 пациентов с делециями IKZF1 были отнесены нами к группе ВГР. В связи с этим при включении делеций IKZF1 в многофакторную модель группа ВГР утрачивала свое неблагоприятное значение как по влиянию на риск неблагоприятного события (ОР – 0,696; 95 % ДИ 0,086–5,636; p = 0,735), так и на риск рецидива (ОР – 0,511; 95 % ДИ 0,053–4,924; p = 0,561), в то время как делеции IKZF1 сохраняли свое негативное влияние и на БСВ (ОР – 4,292; 95 % ДИ 1,521–12,911; p = 0,006), и на риск рецидива (ОР – 9,163; 95 % ДИ 3,131–26,815; p &lt; 0,001). Таким образом, использование комбинации цитогенетических групп риска и MLPA-маркеров для прогнозирования исходов лечения ВП-ОЛЛ у детей не дает существенных преимуществ по сравнению с изолированной оценкой делеций в гене IKZF1. </p></abstract><trans-abstract xml:lang="en"><p>The purpose of the current work was the estimation of prognostic significance of cytogenetic and molecular markers, assessed by multiplex ligation-dependent probe amplification (MLPA) in 142 cases of pediatric B-cell precursor acute lymphoblastic leukemia (BCP-ALL) patients. Good-risk genetic (GEN-GR) group consisted of 114 patients carrying either ETV6-RUNX1 or high hyperdiploidy together with normal copy-number status for all 8 genes (IKZF1, PAX5, ETV6, RB1, BTG1, EBF1, CDKN2A/2B and PAR1) or isolated deletions affecting ETV6/ PAX5/BTG1 and ETV6 deletions with a single additional deletion of BTG1/PAX5/CDKN2A/2B. All other patients (n = 28) were classified to genetic poor risk (GEN-PR) group. GEN-PR features were older age (p = 0.015), stratification to high-risk group of ALL-MB 2008 protocol (p = 0.001), higher initial WBC (p = 0.008), M3 marrow status on day 15 (p = 0.002) and lack of remission on day 36 (p = 0.039). GEN-PR patients had statistically significant lower event-free survival (EFS) (0.59 ± 0.11 vs 0.88 ± 0.03; p = 0.0008), overall survival (OS) (0.63 ± 0.15 vs 0.93 ± 0.02; p = 0.0050) and higher cumulative incidence of relapse (CIR) (0.38 ± 0.12 и 0.06 ± 0.02; p &lt; 0.0001) in comparison to GEN-GR patients. Genetic risk group stratification retained its negative prognostic value in multivariate analysis affecting EFS (hazard ratio (HR) – 2.659; 95 % CI 1.047–6.755; p = 0.040) and CIR (HR – 3.864; 95 % CI 1.226–12.183; p = 0.021), nut did not influenced to OS (HR – 1.479; 95 % CI 0.356–6.139; p = 0.590). There was no prognostic significance of genetic risk group classifier in the “B-other ALL” group. Majority of unfavorable events (9 out of 10) and relapse (8 out of 9) in GEN-PR patients were revealed in case of IKZF1 deletion co-occurrence. Moreover all 15 patients carrying IKZF1 deletions were stratified to GEN-PR group. So when we added IKZF1 deletion as extra variable in the multivariate analysis genetic risk group classification lost its prognostic significance on EFS (HR – 0.696; 95 % CI 0.086–5.636; p = 0,735), and CIR (HR – 0.511; 95 % CI 0.053–4.924; p = 0.561), while IKZF1 deletion remained its prognostic value both to risk of unfavorable event (HR – 4.292; 95 % CI 1.521–12.911; p = 0.006) and risk of relapse (HR – 9.163; 95 % CI 3.131–26.815; p &lt; 0.001). Thus, combination of cytogenetic risk group and MLPA markers did not bring any advantage over detection of isolated IKZF1 deletion for the estimation of prognosis in pediatric BCP-ALL. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>острый лимфобластный лейкоз</kwd><kwd>цитогенетические группы риска</kwd><kwd>дети</kwd><kwd>прогноз</kwd><kwd>факторы риска</kwd><kwd>делеции гена IKZF1</kwd><kwd>MLPA</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute lymphoblastic leukemia</kwd><kwd>cytogenetic risk group</kwd><kwd>children</kwd><kwd>prognosis</kwd><kwd>risk factors</kwd><kwd>IKZF1 deletions</kwd><kwd>MLPA</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">Mullighan C., Su X., Zhang J. et al.; Children’s Oncology Group.
