BACKGROUND Differences in the clinical course of secondary acute myeloid leukemia according to the type of the preceding disorders are not defined. We compared the outcomes of therapy-related acute myeloid leukemia, acute myeloid leukemia following myelodysplastic syndrome and acute myeloiod leukemia following myeloproliferative neoplasm. We also intended to find prognostic factors in secondary...
PURPOSE OF REVIEW The sighting of the Philadelphia chromosome in 1960, later shown to harbor the BCR-ABL mutation in chronic myeloid leukemia, is arguably the most seminal contribution to molecular oncology. In the decades that followed, other cytogenetic and molecular disease markers have been described and effectively incorporated into routine diagnostic tests. This review discusses how this ...
BACKGROUND The myeloproliferative disorders are clonal disorders with frequent somatic gain-of-function alterations affecting tyrosine kinases. In these diseases, there is an increase in DNA damage and a risk of progression to acute leukemia. The molecular mechanisms in myeloproliferative disorders that prevent apoptosis induced by damaged DNA are obscure. METHODS We searched for abnormalitie...
Myelofibrosis (MF) is one of the Philadelphia chromosome-negative clonal myeloproliferative disorders or chronic myeloid disorders, and it is caused by much deposit of collagen substances in bone marrow, definitely is classified as hematopoietic stem cells clonal abnormality, and related to chronic myeloproliferative disorders characterized by striking figure of extra-medullary hematopoiesis. ...
BACKGROUND Polycythemia vera, essential thrombocythemia, and idiopathic myelofibrosis are clonal myeloproliferative disorders arising from a multipotent progenitor. The loss of heterozygosity (LOH) on the short arm of chromosome 9 (9pLOH) in myeloproliferative disorders suggests that 9p harbors a mutation that contributes to the cause of clonal expansion of hematopoietic cells in these diseases...
