Больные хроническим миелолейкозом представляют собой гетерогенную группу. В настоящее время наиболее актуальной проблемой в терапии заболевания является ее персонализация, основанная на индивидуальных характеристиках больного. Цель исследования – изучение индивидуального прогностического значения скорости снижения уровня BCR-ABL в течение первых 3 мес терапии ингибиторами тирозинкиназ. Материал и методы. В исследование включены 54 больных хроническим миелолейкозом в хронической фазе. В качестве терапии 1-й линии больные получали: иматиниб 400 мг/сут (n = 41), нилотиниб 600 мг/сут (n = 12), дазатиниб (n = 1). Уровень относительной экспрессии BCR-ABL гена определяли по международной шкале в момент диагностики, через 3, 6 и 12 мес терапии ингибиторами тирозинкиназ. Оценивали соотношение уровней экспрессии BCR-ABL через 3 мес терапии и в момент диагностики, частоту достижения больными раннего молекулярного ответа через 3 мес лечения (BCR-ABL не более 10%) и большой молекулярный ответ (БМО) через 12 мес терапии, а также соотношение уровня экспрессии BCR-ABL через 3 мес и уровня, достигнутому к 1-му месяцу терапии. Результаты. У 26 (76,5%) из 34 больных с соотношением уровней BCR-ABL через 3 мес терапии и в момент диагностики меньше 0,1 был достигнут БМО к 12-му месяцу терапии, и только у 9 (45%) из 20 больных с соотношением больше 0,1 был достигнут оптимальный ответ на 1 год терапии (p = 0,02). Соотношение уровня экспрессии через 3 мес к уровню через 1 мес также показало, что у 5 (83,3%) из 6 больных с соотношением меньше 0,1 был достигнут БМО на 1 год терапии, при этом только 1 (16,7%) больной с соотношением больше 0,1 достиг оптимального ответа (p = 0,04). При сравнении этих данных с группой больных, достигших раннего молекулярного ответа через 3 мес терапии (BCR-ABL менее 10% IS), получены следующие результаты: 33 (71,7%) из 46 больных с уровнем BCR-ABL не более 10% достигли БМО к 12-му месяцу лечения, и 2 (25%) из 8 больных с уровнем BCR-ABL более 10% достигли БМО на 1 год терапии (p = 0,02). При использовании для прогнозирования достижения оптимального ответа соотношения уровня BCR-ABL через 3 мес терапии к начальному уровню терапии среди больных с ранним молекулярным ответом (BCR-ABL не более 10% на 3 мес терапии) дополнительно были выявлены 5 больных с плохим прогнозом заболевания, которые не достигли БМО к 12-му месяцу. Индивидуальная скорость снижения уровня BCR-ABL в течение первых 3 мес терапии по отношению к начальному индивидуальному уровню может быть использована как прогностический маркер вероятности достижения БМО через 12 мес терапии.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. Chronic myelogenous leukemia (CML) patients represent the heterogeneous group. Several studies in recent years were aimed to personalize treatment based on individual patients characteristics. Aim of study. The aim of our study was to assess prognostic value of individual BCR-ABL decline rate in the first three months of CML therapy to predict optimal response. Patients and methods. Fifty-four patients with chronic phase CML were included in the study. Forty-one patients started treatment with Imatinib 400 mg/day, 12 patients started with Nilotinib 600 mg/day and 1 patient started with Dasatinib 100 mg/day. BCR-ABL level was determined by International Scale at the moment of diagnosis and after 3, 6 and 12 months with ITK therapy. The ratio of BCR-ABL levels at 3 months to baseline for each patient, frequency of the achievement of the early molecular response at 3 months (10% by IS) and MMR at 12 months were assessed; in addition, we calculated ratio of BCR-ABL levels at 3 months to BCR-ABL levels at 1 month. Twenty-six out of 34 patients (76.5%) with ratio of BCR-ABL levels at 3 months to baseline below than 0,1 achieved MMR at 12 months, while only 9 out of 20 patients (45%) with ratio more than 0,1 had optimal response (p = 0.02). Ratio of BCR-ABL levels at 3 months to BCR-ABL levels at 1 month showed much better results with the same (0.1) cut-oﬀ value – 5 out of 6 patients (83.3%) with ratio BCR-ABL levels at 3 months to BCR-ABL levels at 1 month below than 0.1, while only the 1 patient (16.7%) with ratio more than 0.1 achieved optimal response (p = 0.04), respectively. Application of early molecular response at 3 months (10% by IS) yielded worse discrimination results: 33 of 46 (71.7%) patients with BCR-ABL level ≤ 10% at 3 months, whereas 2 of 8 (25%) patients with BCR-ABL &gt; 10% had MMR at 1 year (p = 0.02), respectively. Furthermore, application of our ratio cut-oﬀ value in patients with early molecular response (BCR-ABL level ≤ 10% at 3 months) allowed us to reveal additional 5 high-risk patients who have not reached MMR after 1 year of therapy. Conclusion. Our study showed that individual BCR-ABL level decline rate estimated in the first three months of CML therapy from the baseline to the level measured at 3 months might be useful as an optimal predictor of outcome for CML patients (MMR after 1 year of treatment).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический миелолейкоз</kwd><kwd>индивидуализация терапии</kwd><kwd>ингибиторы тирозинкиназ</kwd><kwd>BCR-ABL</kwd><kwd>большой молекулярный ответ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic myeloid leukemia</kwd><kwd>individualization of therapy</kwd><kwd>tyrosine kinase inhibitors</kwd><kwd>BCR-ABL</kwd><kwd>major molecular response</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">Deininger M., O’Brien S.G., Guilhot F., Goldman J.M., Hochhaus A., Hughes T.P., et al.
