In the giving work incidence of mutation involving genes FLT3, c-KIT, NPM1 having prognostic value in adults is analysed. Kynase domain FLT3 mutation in 18 from 83 patients (21.6%) was detected. 2 from 18 patients (11%) achieved complete remission, 5 from 18 patients (27.7%) with FLT3 mutations were refractory to therapy, two patients died from treatment complications, 9 from 18 (50%) relapsed. Only 2 patients (11%) are alive in continuous complete remission. с-KIT mutations detected in 14.2% (2/14 patients), and NPM1 mutations represented allelic polymorphism. Thus, kynase domain FLT3 mutation are prognostic unfavorable.</p></abstract><trans-abstract xml:lang="ru"><p>Прогноз пациентов с острым миелобластным лейкозом (ОМЛ), получающих интенсивную химиотерапию, определяется как кариотипическими аномалиями, так и мутациями в генах, ответственных за выживание и самоподдержание лейкемических клеток. В данной работе проанализирована частота возникновения мутаций в генах FLT3, c-KIT, NPM1, имеющих принципиальное прогностическое значение у взрослых. Мутации в киназном домене FLT3 выявлены у 18 (21,6%) из 83 пациентов с подлежащими анализу образцами. Клинико-гематологическая ремиссия получена у 2 (11%) из 18 больных, 5 (27,7%) из 18 пациентов с мутациями FLТ3 оказались рефрактерными к проводимому лечению, 2 умерли от осложнений проводимого лечения, у 9 (50%) из 18 развился рецидив ОМЛ. Живы в ремиссии лишь 2 (11%) пациента из 18. Мутации с-KIT выявлены у 14,2% (2 из14 пациентов), а мутации NPM1 представляли собой аллельный полиморфизм. Таким образом, мутации киназного домена FLT3 являются крайне неблагоприятными в прогностическом отношении.</p></trans-abstract><kwd-group xml:lang="en"><kwd>acute myeloid leukemia</kwd><kwd>children</kwd><kwd><italic>FLT3</italic></kwd><kwd>c-KIT</kwd><kwd>NPM1 genes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>острый миелобластный лейкоз</kwd><kwd>дети</kwd><kwd>гены <italic>FLT3</italic></kwd><kwd>с-KIT</kwd><kwd>NPM1</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.
