Background. Much attention has been paid to molecule-genetic diagnostics of chronic myeloid leukemia (CML) and its treatment using new highly effective methods of therapy. The baseline characteristics of patients at primary CML diagnosis are hardly discussed in literature. Aim. To provide clinical, hematological, molecular genetic and demographic characteristics of patients obtained at primary diagnosis of CML. Patients & Methods. Characteristics of CML patients are based on data gathered by the Russian Investigational Group for CML within the international project European Treatment and Outcome Study of CML in Europe (EUTOS, the European Treatment and Outcomes Study). The study included 197 patients with newly diagnosed CML in 6 regions of the Russian Federation (Mordovia, Kirov, Perm (2 sites), Bryansk, Irkutsk, and Chita) over the period from 2009 till 2012. Results. The study demonstrated that 94 % of CML cases were diagnosed in the chronic phase (CP) and 6 % of cases in the acceleration phase (AP) and the blast crisis phase (BC). In 40 % of patients there were no clinical symptoms, and CML was suspected only due to changes in the CBC test. Fatigue was the main subjective complaint presented by 77 % of patients in the CP and 100 % of patients with the AP and BC. Peripheral blood leukocytosis, left shift to immature myeloid cells and increased granulocytic lineage in bone marrow were typical for the patients. In all patients, the CML diagnosis was confirmed by cytogenetic or molecular tests. The social and demographic characteristics of CML patients and comorbidities at diagnosis were analyzed. Conclusion. Based on the results of the study, a modern «portrait of a CML patient» was obtained. The study demonstrated that cytogenetic and molecular methods allow to diagnose CML in most patients at early stages of the disease in the absence of clinical signs of progression. The data on comorbidities require a special attention while choosing a therapy considering its duration. Demographic and social characteristics of CML patients demonstrate that they are socially active, particularly interested in retaining the working capacity and quality of life.

Background & Aims. This paper presents the results of the observational study of ibrutinib in patients with chronic lymphocytic leukemia (CLL), conducted in SP Botkin Municipal Clinical Hospital. The main objective was the analysis of complications of ibrutinib and identification of factors, influencing the dosage regimen; the secondary objective was the estimation of the total response to treatment, event-free and overall survival. Materials & Methods. The study included 96 patients with CLL with indications for ibrutinib therapy. The median age was 64,9 years (range 32-91 years), the study population consisted of 69 (72 %) men and 27 (28 %) women. The condition of 25 (26 %) patients according to the ECOG scale was of > 3 points. The disease of stage C were diagnosed in 36 (37 %) patients. Deletion of 17p/TP53 mutations were detected in 29 (33 %) of 87 patients. Seventy patients had refractory CLL. The median of the number of the lines of the previous therapy was 3 (range 1-9). Adverse events were assessed in accordance with the CTCAE criteria, version 4.0; the bleeding severity was evaluated using ITP-specific bleeding score; hematological complications were classified according to the recommendations of IWCLL-2008. Results. Ibrutinib was administered at a dosage of 420 mg per day daily until progression or intolerable toxicity. The median duration of ibrutinib therapy was 10.3 months. brutinib was shown to have moderate toxicity, mostly of grade I or II. The bleeding was the most frequent complication. Of the hematological complications, thrombocytopenia was the most common (35 %); neutropenia < 1 ^x 10⁹/L was observed in 4 patients. GIT complications were identified in 51 (53 %) patients. Atrial fibrillation was registered in 5 patients, who initially had sinus rhythm. The total of 144 infections were diagnosed in 64 (66 %) patients. Severe infections (> grade III) developed in 26 % of patients. The treatment response was assessed in 92 patients. The overall response to treatment was 89 %. Complete remission, partial remission and partial remission with lymphocytosis were achieved in 4 (4 %), 57 (62 %), and 21 (23 %) patients, respectively. The event-free survival and overall survival by the month 10 was 90 % and 91 %, respectively. For this observation period, ECOG status and the number of the lines of therapy prior to ibrutinib had the prognostic value. Conclusion. Ibrutinib was shown to have high efficiency in relapsed/refractory forms of CLL. The nature of the ibrutinib toxicity is fundamentally different from that of the conventional chemotherapy. The frequency of ibrutinib therapy complications and patients' non-compliance depends on the intensity of the previous treatment of CLL. Despite a short observation period, it can be concluded that ibrutinib had the greatest impact on the patient's quality of life when administered for the first relapse. The low toxicity of ibrutinib is likely to allow the combination with other antitumor agents.

Цель. Анализ нежелательных сердечно-сосудистых явлений у больных хроническим миелолейкозом (ХМЛ), получавших различные ингибиторы тирозинкиназы (ИТК). Материалы и методы. В исследование включено 97 пациентов с ХМЛ, имевших показания к назначению нилотиниба, дазатиниба или иматиниба. Ко времени обследования пациенты получали лечение ИТК в течение 1-138 мес. Из них 3 больных на протяжении наблюдения получали последовательно 2 препарата. Все пациенты с ХМЛ были в возрасте 22-79 лет (медиана 53,5 года): 55 женщин в возрасте 22-71 год (медиана 53,5 года) и 42 мужчины в возрасте 24-79 лет (медиана 53 года). Результаты. Сравнительный анализ показал статистически значимо большее влияние нилотиниба на продолжительность максимального суточного интервала QTc по сравнению с другими ИТК. У пациентов, получавших нилотиниб (n = 15), при сроке приема более 38 мес. QTc был 0,47 с (межквартильный интервал [МКИ] 0,46-0,47 с), в группе иматиниба (n = 17)-0,43 с (МКИ 0,43-0,44 с), дазатиниба (n = 4)-0,43 с (МКИ 0,42-0,44 с) (p = 0,0008). Доля больных с QTc > 0,46 с среди всех получавших нилотиниб составила 62 % (31/50), в группах иматиниба (6/41) и дазатиниба (2/18)-14,6 и 11,1 % соответственно (p = 0,0008). У 5 пациентов QTc был более 0,48 с, что служит показанием к прекращению лечения или к редукции дозы препарата. У 2 пациентов выявленные изменения продолжительности интервала QTc потребовали временной отмены ИТК. При отмене или снижении дозы нилотиниба во всех

Background & Aims. The article presents results of two observational, prospective, multicenter studies “Quality of Life, Symptom Profile, and Adherence to Treatment in Adult Patients with Newly Diagnosed Chronic Phase Chronic Myeloid Leukemia Receiving Dasatinib” (20122015) and “Quality of Life and Symptom Profile in Imatinib-Resistant or Intolerant Patients with Chronic Myeloid Leukemia” (2011-2014). Methods. Data of 107 patients with chronic myeloid leukemia in chronic phase were involved in the real-world analysis - 32 newly diagnosed patients on first-line treatment with dasatinib or after yearly switch to dasatinib after ima-tinib treatment failure and 75 imatinib-resistant or intolerant patients on second-line treatment with dasatinib. Treatment effectiveness and safety of dasatinib were assessed during first- and second-line dasatinib treatment using clinical outcomes as well as quality of life and symptom profile assessment. Results. The real-world data obtained during observational study in limited population of CML patients conform the results of clinical trials devoted to evaluation of treatment efficacy and safety of dasatinib treatment in first- and second-line treatment and demonstrate the importance of patient-reported outcomes. Patient's quality of life improved within 12 months of the first-line dasatinib therapy according to the following scales: role physical functioning, pain, vitality, social functioning and role emotional functioning. The most pronounced and clinically significant improvement was observed for the role emotional functioning (51.1 vs. 68.9). During the second-line dasatinib treatment, stabilization of quality of life parameters was registered for the following scales: vitality, social functioning, mental health, and pain. Significant improvement of the Integral Quality of Life Index was observed (p < 0.05). Positive dynamics of relevant symptoms was registered. The symptom severity decreased during both the first- and second-line therapy. Conclusion. Quality of life and symptom assessment in CML patients contribute to a better disease control in accordance with the principles of risk-adaptive therapy.
