ABSTRACT

Acute lymphoblastic leukemia is one of the groups of most challenging malignant neoplasms of hematopoietic tissue. Despite the success in achieving remission induction in primary patients, later, most of them develop disease relapses. Overall and disease-free survivals have to be improved, which cannot be achieved solely with chemotherapy intensification. The new target drugs and cell technologies improve the treatment options for the resistant forms and relapses of acute lymphoblastic leukemia. The effective use of new drugs presupposes their timely assignment which can be ensured by their availability in routine clinical practice. The provided case report describes the successful use of bispecific antibody blinatumomab for treating an early relapse of acute lymphoblastic leukemia in the clinical practice within the municipal healthcare system.

Keywords: acute lymphoblastic leukemia, clinical practice, target therapy, blinatumomab.

ABSTRACT

Aim. To evaluate the clinical experience of bosutinib use for treatment of chronic myeloid leukemia (CML) patients with intolerance and resistance to other tyrosine kinase inhibitors (TKI), as well as to compare the obtained results with the data of clinical trials.

Materials & Methods. The analysis was conducted on case history records of 51 CML patients (25 men and 26 women; median age was 56 years, range 28–86). By the beginning of bosutinib therapy 37 chronic phase, 8 acceleration phase, and 6 blast crisis patients were included in the study. Bosutinib was administered as second–line TKI treatment in 10 patients, as third–line treatment in 18 patients, and as fourth–line treatment in 23 patients. The causes for switching to bosutinib were poor tolerance of previous TKI therapy in 21 patients and resistance to previous TKI therapy in 30 patients.

Results. The median duration of bosutinib treatment was 6 months (range 1–50). Bosutinib toxicity profile and its tolerance in common clinical practice corresponded to the data of clinical trials. Because of adverse events the therapy was discontinued only in 5 (10 %) patients. Complete hematological response was 88 % (persistent response was maintained in 76 % of patients); complete cytogenetic response (CCyR) was 39 %, (persistent response in 37 % of cases); major molecular response (MMR) was 31 % (it was confirmed in 25 % of patients during the last follow-up visit). The efficacy of bosutinib in the real clinical setting was slightly higher compared to the results of clinical trials. This difference was associated with a disease phase, a reason for withdrawal of the previous TKI, line of treatment, BCR–ABL mutations, and the form of them. The therapy was continued in 22 (43 %) patients, most of them reached stable optimal response, both CCyR and MMR.

Conclusion. Bosutinib appears to be an acceptable alternative to other TKIs having its specific mechanisms of action and adverse events. The efficacy and safety of bosutinib proved in routine clinical practice are sufficient to recommend it for use in national hematology.

Keywords: chronic myeloid leukemia, bosutinib, target therapy, tyrosine kinase inhibitors, clinical practice.

ABSTRACT

Background & Aims. Interpretation of key aspects of pathogenesis of chronic myeloid leukemia (CML) and development and introduction of target therapy have changed the prognosis of this once fatal disease dramatically. Results of numerous clinical trials demonstrated substantial superiority of tyrosine kinase inhibitors over previous therapy techniques. At the same time, clinical trials had limitations in patient enrollment, as well as treatment conditions and duration. The analysis of our clinical experience in CML target therapy (over the period from 2003 till 2015) is an important argument for introduction of novel drugs into routine clinical practice. The aim of the study is to analyze our own experience in CML target therapy and to compare our results with clinical trials data.

Methods. Outpatient’s cards and case histories of CML patients treated in the Russian Scientific Research Institute of Hematology and Transfusiology over last 12 years were analyzed in this work. Published results of multi-center clinical trials evaluating the use of tyrosine kinase inhibitors in CML were used for a comparative analysis. The primary morbidity rate and the prevalence of CML, results of first and subsequent treatment lines were studied with assessment of survival rates, adverse events, and the nature of the response (hematologic, cytogenetic and molecular).

Results. The experience in treatment of 208 CML patients was analyzed. The use of imatinib led to clinical and hematological remission (complete hematologic response) was achieved in 95 % of patients. The frequency of complete cytogenetic responses (CCyR) was 69 %, and that of major molecular responses (MMR) was 58 %. The overall 5-year survival (OS) was 86.4 %, the 10-years OS was 67.5 %. The use of nilotinib during the second line permitted to achieve CCyR in 61 % of patients, and the MMR in 55 % of cases. The two-year OS was 96 % and the 5-year OS was 68 %. CCyR and MMR were achieved in 50 % patients treated with dasatinib during the second line. As for the third line, CCyR was achieved in 50 % of patients and MMR in 25 %. In case of previous imatinib and nilotinib resistance, CCyR was observed only in 36 % of patients and MMR in 18 % of cases. During second-line dasatinib treatment, the 2-year OS was 85 %, and the 5-year OS was 51 %; as for the third line, the results were 75 % and 50 %, respectively. The range and rates of adverse events of the therapy, in general, corresponded to results of clinical trials.

Conclusion. The use of tyrosine kinase inhibitors in treatment of CML permits to prolong patient’s life span and quality of life significantly. The use of nilotinib and dazatinib (in case of nilotinib intolerance and/or resistance) could be effective in most patients.

Keywords: chronic myeloid leukemia, target therapy, tyrosine kinase inhibitors, imatinib, nilotinib, dasatinib, clinical practice.

ABSTRACT

Background & Aims. Polycythemia vera (PV) refers to a group of classic Ph-negative myeloproliferative neoplasms characterized by panmyelosis, pancytosis, high risk of thrombotic and hemorrhagic complications, poor quality of life due to symptoms of tumor proliferation. Low-dose acetylsalicylic acid and phlebotomy/erythrocytapheresis are recommended for patients at low risk of complications, while the cytoreductive therapy (hydroxyurea or interferon alpha) is recommended for patients at high risk of thrombotic and hemorrhagic complications. At present, much attention is paid to the problems of diagnosis and treatment PV.

Methods. The article presents a brief description of the condition, a review of modern methods of treatment, results of observation over 100 PV patients who have been treated in the outpatient department of the Hematology Research Center. The observation period ranged from 6 to 262 months (median follow-up is 14 months).

Results. Patients’ age ranged from 23 to 80 years (median 56 years); 67 % of them were women, and 33 % were men. PV was diagnosed according to 2008 WHO guidelines. JAK2V617F mutation was detected in 100 % of cases. Splenomegaly was found in 70 % of patients. Plethoric symptoms (such as facial and hand hyperemia, and scleral injection) were found in 65 % of patients. All patients complained of headaches and dizziness, and 25 % of patients complained of itching. All patients received symptomatic therapy, antiaggregants, medications improving microcirculation, or antihypoxants. Patients were treated according to clinical guidelines: 49 % of them received hydroxyurea, 14 % IFN a-2b, 14 % a combination therapy (hydroxyurea and phlebotomy or IFN a-2b and phlebotomy), and 23 % of patients phlebotomy alone. Response to treatment was evaluated according to 2009 European LeukemiaNet criteria. Among all patients, the frequency of complete remission was 48 %, the partial response rate was 41 %, and no effect was achieved in 11 % of patients regardless they received therapy or not. The therapy was changed, if the treatment had proved to be ineffective, or in case of intolerance or complications. Complete remission was not achieved after switching treatment from one method to another.

Conclusion. Treatment of PV is mainly symptomatic. The effectiveness of first line therapy (complete remission) ranged from 14.5 to 71 %. It is necessary to conduct clinical trials designed to evaluate the effectiveness and safety of new targeted therapies.
