In contrast to acute lymphoblastic leukemia in children, adult cases of this disease are associated with a very poor prognosis. In order to ascertain whether the frequencies and patterns of submicroscopic changes, identifiable with single nucleotide polymorphism array analysis, differ between childhood and adult acute lymphoblastic leukemia, we performed single nucleotide polymorphism array ana...
Philadelphia chromosome-positive acute lymphoblastic leukemia occurs in two molecular forms, those with and those without rearrangement of the breakpoint cluster region on chromosome 22. The molecular abnormality in the former group is similar to that found in chronic myelogenous leukemia. To characterize the abnormality in the breakpoint cluster region-unrearranged form, we have mapped a 9;22 ...
Further improvement of outcome in childhood acute lymphoblastic leukemia could be achieved by identifying additional high-risk patients who may benefit from intensified treatment. We earlier identified PTPRC (CD45) gene expression as a potential new stratification marker and now analyzed the prognostic relevance of CD45 protein expression. CD45 was measured by flow cytometry in 1065 patients tr...
A human serum (obtained from a multiparous and multiple-transfused patient with chronic myelogenous leukemia) and a rabbit antiserum (obtained by immunization with papain extracts from a B-lymphoblastoid cell line) showed reactivity against antigenic specificities (different from HLA) expressed on peripheral blood B-lymphocytes, unmarked lymphocytes, and monocytes. These antigenic determinants ...
A monoclonal antibody designated PI153/3, which reacts with neuroblastoma and fetal brain, is shown to identify also a cell surface determinant shared by pre-B and mature B cells and their corresponding leukemias including chronic lymphocytic leukemia, non-Hodgkin's lymphoma, B acute lymphoblastic leukemia, and hairy cell leukemia, but not plasmacytoma. Almost all non-T, non-B acute "lymphoid" ...
Atypical chronic myeloid leukemia (aCML) is a rare chronic myeloproliferative disorder characterized by leukocytosis, absence of Philadelphia chromosome or BCR-ABL rearrangement, and marked myeloid dysplasia. The diagnosis of aCML is difficult and challenging, more so if the initial presentation is with blast crisis. In the absence of characteristic mutational profile, blast crisis of aCML can ...

Ингибиторы тирозинкиназ: профилактика рецидива после аллогенной трансплантации гемопоэтических стволовых клеток у взрослых пациентов с Ph-позитивным острым лимфобластным лейкозомTyrosine kinase inhibitors: relapse prophylaxis after allogeneic hematopoietic stem cell transplantation in adults with Philadelphia chromosome-positive acute lymphoblastic leukemia
BACKGROUND Mixed phenotype acute leukemia (MPAL) represents a diagnostic and therapeutic dilemma. The European Group for the Immunological Classification of Leukemias (EGIL) scoring system unambiguously defines MPAL expressing aberrant lineage markers. Discussions surrounding it have focused on scoring details, and information is limited regarding its biological, clinical and prognostic signifi...
INTRODUCTION Acute lymphoblastic leukemia (ALL) is disease of lymphoid precursors and is the most common cancer. Diagnosis of ALL is made by evaluating morphology and flowcytometric Immunophenotyping (FCI)and is an important adjunct in diagnosis and determining treatment in ALL, with availability of extensive monoclonal antibodies in the recent years there is tremendous progress in the field of...
