BCR-ABL kinase domain mutations were detected in 30.5 % (11 of 36) of those patients. Most of identified mutations were missense mutations: Q252H, M244V, G250E, Y253F/H, E255K/V, T315I, M351T, F359V, F359C, F486S. Patients with BCR-ABL mutations have significantly lower 4-year event-free survival compared with CML patients without mutations (18 % vs. 53 %; р = 0.003). The results can be used as reference information in deciding on therapy in imatinib resistant CML patients with clinically relevant BCR-ABL mutations.</p></abstract><trans-abstract xml:lang="ru"><p>В исследовании проводится анализ мутационного статуса у 36 больных Ph+ хроническим миелолейкозом (ХМЛ) в хронической стадии с первичной и вторичной резистентностью к терапии матинибом. Мутации гена BCR-ABL определены методом прямого секвенирования ДНК. В результате исследования мутации киназного домена BCR-ABL были обнаружены у 30,5 % (у 11 из 36) этих больных. Большинство выявленных мутаций относились к миссенс-мутациям: Q252H, M244V, G250E, Y253F/H, E255K/V, T315I, M351T, F359V, F359C, F486S. Показана значительно более низкая бессобытийная 4-летняя выживаемость больных ХМЛ с обнаруженными мутациями гена BCR-ABL по сравнению с больными ХМЛ без мутаций (18 % vs 53 %; р = 0,003). Результаты исследования могут быть использованы в качестве справочного материала при принятии решений о тактике лечения резистентных к иматинибу больных ХМЛ с клинически значимыми мутациями гена BCR-ABL.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chronic myeloid leukemia</kwd><kwd>BCR-ABL mutations</kwd><kwd>resistance</kwd><kwd>imatinib</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хронический миелолейкоз</kwd><kwd>мутации гена BCR-ABL</kwd><kwd>резистентность</kwd><kwd>иматиниб</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.
