Ultrastructural cytochemical analysis of blastic transformation of chronic myelocytic leukemia.
Ultrastructural cytochemical changes occurring during the blast phase of chronic myelocytic leukemia (CML) are described. Normal developing promyelocytes contain myeloperoxidase (MPO) -positive rough endoplasmic reticulum, nuclear envelope, and Golgi apparatus. All secretory granules of normal promyelocytes are also MPO-positive. In this study we have found abnormal promyelocytes with MPO-posit...
متن کاملChronic myeloid leukemia: mechanisms of blastic transformation.
The BCR-ABL1 oncoprotein transforms pluripotent HSCs and initiates chronic myeloid leukemia (CML). Patients with early phase (also known as chronic phase [CP]) disease usually respond to treatment with ABL tyrosine kinase inhibitors (TKIs), although some patients who respond initially later become resistant. In most patients, TKIs reduce the leukemia cell load substantially, but the cells from ...
متن کاملKaryotype evolution and multilineage involvement of Philadelphia chromosome-positive clones in blastic transformation of two patients with chronic myelocytic leukemia.
Simultaneous analysis of the cell morphology and karyotypes on single colonies was carried out in two patients with Philadelphia chromosome (Ph1)-positive chronic myelocytic leukemia in blastic transformation in order to clarify the origin of leukemic cells involved. Patient no. 1 was in a typical myeloblastic transformation and patient no. 2 in "basophilic transformation." Both patients exhibi...
متن کاملBlastic crisis and myelofibrosis, simultaneous complications in a case of chronic myelocytic leukemia.
A case of chronic myelocytic leukemia is reported. He developed blastic crisis as well as myelofibrosis, simultaneously as a complication, after 1-1/2 years treatment with myeleran.
متن کاملPersistence of Chronic Myelocytic Leukemia
Chronic myelocytic leukemia (CML)' is a clonal pluripotent stem cell disease, clinically divided into a chronic phase of a median duration of ^-4 yr, followed by an acute phase (blast crisis) lasting for few months (1) . Cytogenetic hallmark of most (95%) CML cases is the presence of the Philadelphia (Ph) chromosome, resulting from a reciprocal translocation between chromosomes 9 and 22 (2, 3) ...
