Treatment started a dose of 600 mg/day. At the insufficient primary therapy response or loss complete hematological and/or complete cytogenetic remission in the course of treatment, dose have been increased to 800 mg/day. In 82 (78.1%) patients complete hematological remissions have been reached. In 44 (41.9%) patients complete cytogenetic response (CR) is received, and in 27 (61.4 %) of them with molecular response: complete — 17 (63%) and major — 10 (27%). 6-year overall survival rate (OS) was 61.9%, 6-year event-free survival rate (EFS) — 30.5%. Achievement of complete CR was a predictor of long longterm survival rate: OS — 95.5% versus 37.7 % (р &lt;0.001). In case of absence CR (n=16) imatinib dose escalation allowed to receive complete CR in 5 (31.25%) and minor — in 4 (25.0%) patients. Loss or absence of complete CR on imatinib therapy not always leads to CML progression: in 18 (17.1 %) patients without complete CR hematological parameters remain normal and there are no signs of disease progression.</p></abstract><trans-abstract xml:lang="ru"><p>Цель работы — исследование долгосрочной результативности лечения иматинибом мезилатом больных хроническим миелолейкозом (ХМЛ) в фазе акселерации и определение оптимального дозовременного режима терапии. С февраля 2001 г. по февраль 2007 г. в исследование были включены 105 пациентов (46 мужчин, 59 женщин) в возрасте от 15 до 74 (медиана — 40) лет. Лечение начинали с дозы 600 мг/сут. При недостаточном первичном ответе на терапию или потере полной клинико-гематологической и/или полной цитогенетической ремиссии в процессе лечения дозу эскалировали до 800 мг/сут. Полной клинико-гематологической ремиссии достигли 82 (78,1%) пациента, полный цитогенетический ответ (ЦО) получен у 44 (41,9%) больных (медиана — 6 мес). У 27 (61,4%) из 44 пациентов с полным ЦО достигнут молекулярный ответ: полный — 17 (63%) и частичный—10 (27%). Шестилетняя общая выживаемость (ОВ) составила 61,9%, 6-летняя бессобытийная (БСВ) — 30,5%. Предиктором длительной долгосрочной выживаемости было достижение полного ЦО: ОВ 95,5% против 37,7% (р&lt;0,001). В случае отсутствия ЦО эскалация дозы иматиниба позволила получить полный ЦО у 5 (31,25%) и малый— у 4 (25,0%) из 16 пациентов. Потеря или отсутствие полного ЦО на терапии иматинибом не всегда приводит к прогрессии ХМЛ: у 18 (17,1%) больных без полного ЦО сохраняются нормальные клинико-гематологические показатели и отсутствуют признаки прогрессии заболевания.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chronic myeloid leukemia</kwd><kwd>acceleration phase</kwd><kwd>imatinib</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хронический миелолейкоз</kwd><kwd>фаза акселерации</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.
