Data on possibilities of personalized approach for direct oral anticoagulants (DOAC) choice in patients with atrial fibrillation are presented in the article. We also review clinical and fundamental studies and future perspectives on pharmacogenetic and pharmacokinetic tests to predict the efficacy and safety of DOAC.

Multicenter Study Clinical Trial
[Russian multicenter clinical trials in acute leukemias].
The paper describes the results of 15 consecutive Russian clinical trials in the treatment of different types of acute leukemias, conducted by Russian cooperative group within the last 27-years and included more than 25 hundred patients. It was shown that the 5-years overall survival in AML younger than 60 years patients improved from 20 to 33%, in ALL - from 38 to 65%, in APL - from 0 to 95%. The cooperative work resulted in balanced clinical recommendations and protocols, reproducible in regional hospitals. ⋯ Non - chemotherapeutic approach with arsenic trioxide and all - trans retinoid acid had dramatically changed the toxicity and duration of treatment with very high efficacy. The Russian cooperative group was the first that started to include pregnant women with acute leukemias into clinical trials. This prospective and prolonged experience has shown that pregnancy in acute myeloid leukemia is an extremely poor prognostic factor, but it does not influence the outcome in acute lymphoblastic leukemia.

Review Case Reports
[Pure red cell aplasia of the bone marrow in combination with thymoma. A literature review and own data].
Eight patients were observed with a rare combination of thymoma and pure red cell aplasia of bone marrow (PRCA), of which seven women were between 44 to 68 years old. The diagnosis of PRCA was established before the detection of thymoma in 1 patient, simultaneously in 3, after - in 4. Seven patients underwent timomectomy. ⋯ It is shown that the lifespan of red blood cells are not changed. The direct Coombs test was negative in 5 patients, but with the help of aggregate hemaglutination test and enzyme immunoassay, antibodies were detected on the surface of erythrocytes. The pathogenesis of this combination of diseases remains unclear and needs to be elucidated.

Mantle cell lymphoma (MCL) is aggressive B-cell neoplasm diagnosed predominantly among older men. R-CHOP-like regimens allow to achieve high response rate, but the overall survival (OS) are disappointingly short - 3-4 years. An addition of high - dose cytarabine to the upfront therapy and autoSCT significantly improved outcomes but remain feasible largely for medically fit patients. Based on the activity and good tolerance of gemcitabine - oxaliplatin schemes in relapsed and refractory MCL patients, we developed an alternative first - line course for patients who are not eligible for R-HD-MTX-AraC.

Aim of the issue was to determine indications for intratecal chemotherapy drugs administration to prevent relapse of diffuse large B-cell lymphoma (DLBCL) with central nervous system (CNS) involvement.
