Primary mediastinal large B-cell lymphoma (PMBCL) is a distinct type of large B-cell lymphoma. In this type of the disease, the neoplastic process is located in the anterior and superior mediastinum, frequently with compression of the superior vena cava and with tumor invasion into the adjacent organs and tissues: the pericardium, lung, pleura, etc. Despite(More)
Double-hit (DH) lymphoma, an extremely aggressive variant of B-cell lymphoma, is accompanied by chromosomal abnormalities leading to the activation of a few oncogenes, one of which is the c-MYC gene in conjunction with BCL2 or BCL6 gene rearrangements. There are most common cases of MYC/8q24 and BCL2/18q21 gene rearrangements (MYC/BCL-2 DH lymphoma). The(More)
AIM To make a randomized comparison of 2 consolidation treatment options (two patient groups): 2 cycles of cytarabine in average (Ig/m2 in Group 2) and standard (100 mg/mi2 in Group 1) doses in combination with idarubicin (8-12 mg/m2) and mitoxantrone (10 mg/m2), after two 7+3 induction cycles of daunorubicin (60 mg/mi2) and subsequent 6 cycles of(More)
A comparison of chromosomal abnormalities in bone marrow leukaemic cells and of stable and unstable aberrations in lymphocytes of patients with hematological malignancies who live in areas with or without contamination by the Chernobyl nuclear accident has been made using FISH and G-banding. Healthy residents of these areas comprised the control group. No(More)
AIM To investigate characteristics of the course and efficacy of treatment of diffuse large B-cell lymphosarcoma (DLBL) with primary lesion of the spleen. MATERIAL AND METHODS From 1998 to 2006, primary splenic lesion was registered in 15 of 120 patients with DLBL and affected lymph nodes (LN), spleen and Waldeyer's ring. The diagnosis was made according(More)
AIM To evaluate the efficiency and toxicity of the intensive Burkitt's lymphoma (BL) therapy protocol BL-M-04. SUBJECTS AND METHODS A total of 70 patients diagnosed with BL, including 45 men and 25 women whose age was 15 to 62 years (median age 31 years), were followed up in 2003 to 2014. Stage I (according to S. Murphy) was diagnosed in 4 (5.7%)(More)
In the past decade, a notable advance has been made in the understanding of the pathogenesis of NK/T-cell lymphomas; however, their diagnosis remains difficult because of their rarity and clinical and morphological variabilities. The paper generalizes the ten-year experience of the Hematology Research Center, Ministry of Health of Russia, in diagnosing and(More)
AIM To analyse efficacy and tolerance of high-dose polychemotherapy (PCT) of Berkitt's lymphoma (BL) in patients aged over 40 years. MATERIAL AND METHODS High-dose PCT was given to 6 BL patients aged 41-56 years (median 48.1 years). RESULTS Complete clinicohematological remissions were achieved in 4 patients. In two of them the treatment was(More)
