Minimal residual disease (MRD) estimated in bone marrow by three-color flow cytometry on day 15 (n=99), day 36 (n=107) and before the maintenance therapy (n=60). Day 36 positive MRD level (≥0.01%) as one of unfavorable factors statistically significant worsening of relapse-free survival was revealed (log-rank test; р&lt;0.05). In multifactorial analysis (Cox regression) it is revealed that positive MRD level on day 36 of treatment is the strongest and independent prognostic factor influencing relapse probability (hazard ratio 6.6; p=0.031). Necessity of additional patients' stratification introduction according to MRD level after induction is proved.</p></abstract><trans-abstract xml:lang="ru"><p>В исследование включены 220 детей с острым лимфобластным лейкозом (ОЛЛ), лечившихся по протоколу ОЛЛ-МБ-2002. Минимальную остаточную болезнь (МОБ) оценивали в костном мозге методом трехцветной проточной цитофлюориметрии на 15-й (n=99) и 36-й (n=107) дни и перед началом поддерживающей терапии (n=60). Установлено, что одним из неблагоприятных факторов, статистически достоверно (log-rank-тест; р&lt;0,05) ухудшающих безрецидивную выживаемость, является наличие положительного уровня МОБ на 36-й день (≥0,01%). В мультифакторном анализе (Кокс-регрессия) выявлено, что положительный уровень МОБ на 36-й день – самый сильный и независимый прогностический фактор, влияющий на вероятность развития рецидива (hazard ratio 6,6; p=0,031). Обоснована необходимость введения дополнительной стратификации пациентов на терапевтические группы с учетом уровня МОБ после индукционной терапии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>минимальная остаточная болезнь</kwd><kwd>дети</kwd><kwd>острый лимфобластный лейкоз</kwd><kwd>прогноз</kwd><kwd>безрецидивная выживаемость</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>минимальная остаточная болезнь</kwd><kwd>дети</kwd><kwd>острый лимфобластный лейкоз</kwd><kwd>прогноз</kwd><kwd>безрецидивная выживаемость</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.
