В ходе работы было выявлено, что среди клеток с фенотипом СD34+СD38- преобладали лейкемические предшественники В-клеток с фенотипом СD34+СD38-CD19+. Большее процентное содержание как СD34+СD38-, так и СD34+СD38-CD19+ среди общей популяции лейкемических клеток ассоциировалось с худшим ответом на терапию. Поэтому исходное количество таких клеток может рассматриваться как прогностический маркер при ОЛЛ у детей.</p></abstract><trans-abstract xml:lang="en"><p>The number of the supposed leukemic stem cells in marrow samples of 54 patients with primary B-linear acute lymphoblastic leukemia was detected by the method of multiparametric flow cytofluorimetry in leukemia diagnosis (zero day). The level of minimal residual disease was estimated on zero and on the fifteenth days of induction therapy. In the course of the research it was found out that leukemic B-cell precursors with СD34+СD38-CD19+ phenotype prevailed among the cells with СD34+СD38-phenotype. The high percentage of both СD34+СD38-, СD34+СD38-, and СD34+СD38-CD19+ among the general population leukemic cells was associated with a worse response to the therapy. Therefore, the initial number of such cells can be considered as a prognostic marker in acute lymphoblastic leukemia in children.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>острый лимфобластный лейкоз</kwd><kwd>минимальная остаточная болезнь</kwd><kwd>acute lymphoblastic leukemia</kwd><kwd>minimal residual disease</kwd><kwd>flow cytofluometry</kwd><kwd>leukemic stem cells</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">Определение остаточных опухолевых клеток в костном мозге детей с B-линейным острым лимфобластным лейкозом методом проточной цитофлюорометрии / М.
