Myeloid malignancies: myelodysplastic syndromes, myeloproliferative disorders, and acute myeloid leukemia.
As hematopoietic cells proceed in differentiation from stem cells to committed progenitors to later stage mature forms, they undergo a sequence of morphologic, immunophenotypic, and functional changes that are a consequence of interaction between the underlying cellular genetic program and environmental cues, are linear for each cell lineage, and result in a pattern of antigenic expression rela...
متن کاملSpliceosome mutations in myelodysplastic syndromes and chronic myelomonocytic leukemia
The recently discovered spliceosome mutations represent a group of acquired genetic alterations that affect both myeloid and lymphoid malignancies. A substantial proportion of patients with myelodysplastic syndromes (MDS), chronic myelomonocytoic leukemia (CMML) or chronic lymphocytic leukemia (CLL) harbor such mutations, which are often missense in type. Genotype-phenotype correlations have be...
متن کاملChronic Myeloproliferative Disorders
JAK2, an acquired mutation of JAK2, is present in a majority of patients with polycythemia vera and to a lesser extent among patients with the other myeloproliferative disorders. We analyzed the effect of JAK2 on the expression of polycythemia rubra vera 1(PRV-1), using an in vitro model. Compared to wild-type JAK2, the presence of JAK2 increased both PRV-1 protein and mRNA levels in murine mye...
متن کاملChronic myeloproliferative disorders.
The Philadelphia chromosome-negative chronic myeloproliferative disorders (CMPD), polycythemia vera (PV), essential thrombocythemia (ET) and chronic idiopathic myelofibrosis (IMF), have overlapping clinical features but exhibit different natural histories and different therapeutic requirements. Phenotypic mimicry amongst these disorders and between them and nonclonal hematopoietic disorders, la...
متن کاملleukaemia, myelodysplastic syndromes, and chronic myeloid leukaemia
Introduction The standard approach to the diagnosis of acute leukaemia and myelodysplasia has been based on the morphology and percentage of malignant haemopoietic cells in peripheral blood and in an aspirated sample of bone marrow. The FAB group reports on acute leukaemia have emphasised the value of additional information gained from cytochemistry,' and immunological studies and cytogenetics ...
