Background. Chronic myeloid leukemia is a hematological malignancy caused by expression of BCR-ABL tyrosine kinase oncogene, product of the t(9;22) Philadelphia translocation. Accelerated phase of this disease marks the onset of advanced rapidly progressive disease unresponsive to many therapies. Pregnancy limits broad number of therapies on patients because of their potential teratogenic effec...
GATA family proteins play essential roles in development of many cell types, including hematopoietic, cardiac, and endodermal lineages. The first three factors, GATAs 1, 2, and 3, are essential for normal hematopoiesis, and their mutations are responsible for a variety of blood disorders. Acquired and inherited GATA1 mutations contribute to Diamond-Blackfan anemia, acute megakaryoblastic leukem...
Transient myeloproliferative disorder is a hematological condition observed during the neonatal period in patients with Down syndrome [1]. This disorder mimics congenital leukemia and the blast cells were often reported to show characteristics compatible with those of megakaryoblasts [2] or pluripotent stem cells [3]. Although this disorder usually resolves gradually without antileukemic treatm...
BACKGROUND AND OBJECTIVES The two main complications of severe chronic neutropenia are fatal sepsis and myelodysplasia/acute leukemia (MDS/AL). Granulocyte colony-stimulating factor (G-CSF) therapy has significantly reduced the frequency and severity of infections, but its possible influence on the risk of malignancy is not known. DESIGN AND METHODS The French Severe Chronic Neutropenia (SCN)...
OBJECTIVE: To evaluate the association between living close to solid waste landfi ll sites and occurrences of cancer and congenital malformations among populations in their vicinity. METHODS: Deaths among people living in the municipality of São Paulo, Southeastern Brazil, between 1998 and 2002 were selected and geocoded, according to selected causes. Over the period evaluated, there were 351 d...
Our understanding of the pathogenesis of congenital and acquired neutropenia is rapidly evolving. New ground-breaking observations have identified the genes responsible for many of the congenital neutropenia syndromes and are also providing new insights into normal neutrophil commitment and differentiation. Acquired neutropenia remains a poorly understood syndrome, although new insights into it...
