Treatment with erythropoietin (epo) may improve the anemia of myelodysplastic syndromes (MDS) in approximately 20% of patients. Previous studies have suggested that treatment with the combination of granulocyte colony-stimulating factor (G-CSF) and epo may increase this response rate. In the present phase II study, patients with MDS and anemia were randomized to treatment with G-CSF + epo accor...
Attention has been increasing focused on the role of the bone marrow microenvironment in the pathogenesis and progression of hematological malignancies, including myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML).1–3 Thus, the identification of genes or proteins that are differentially expressed in the abnormal bone marrow niche may provide new therapeutic opportunities and persp...
One hundred and seventeen consecutive patients with refractory dysmyelopoietic anemia (RDA) were followed and studied over 6 yr. All RDA cases had at least two marrow cell lines involved with dysplasia and usually all three. Morphologically, the series could be divided into 55 cases that had primarily "erythroid" hyperplasia and 62 cases with primarily "myeloid" dysplasia. There was a significa...
The EVI1 gene encodes a zinc-finger, DNA-binding protein originally described as the transforming gene associated with a common ecotropic viral insertion site in myeloid leukemias. Previous studies demonstrated EVI1 expression in human leukemias in cases with 3q26 translocations, but not in normal blood or bone marrow. These studies also suggested an association between EVI1 expression and chro...
Acquired chromosomal abnormalities are important prognostic factors in patients with myelodysplastic syndromes treated with supportive care and with disease-modifying therapeutic interventions, including allogeneic hematopoietic stem cell transplantation. To assess the prognostic impact of cytogenetic characteristics after hematopoietic stem cell transplantation accurately, we investigated a ho...
Congenital hypoplastic anemia is a rare disease characterized by a normochromic, normocytic anemia, a deficiency of erythroblasts in the marrow, and normal leukocyte and platelet counts. The disease usually is treated successfully with corticosteroid therapy; however, some patients become refractory to corticosteroids and must receive washed, packed red blood cell transfusions. The management a...
Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterized by small vessel vasculopathy, autoantibodies, and skin or visceral organ fibrosis (lung, oesophagus, kidney etc.) as a result of extracellular collagen deposition. The cancer risk is higher in many rheumatic diseases, including SSc. Various defined malignancies may develop in 3%-11% of patients with SSc. These sol...
BACKGROUND Recalcitrant pyodermic lesions and neutrophilic dermatoses are often associated with subclinical myelodysplastic syndrome (MDS). In this case series, we assessed the diagnostic importance of karyotypic analysis of bone marrow cells in 4 patients with MDS-associated pyodermic eruptions treated at our university hospital. Karyotypic analysis was performed in bone marrow cells and perip...
Previous studies have shown that the cyclin-dependent kiterestingly, the p15 gene was frequently methylated in patients with high-risk MDS (refractory anemia with excess nase inhibitor (CDKI) genes p15 and p16 are frequently inactivated by genetic alterations in many malignant blasts [RAEB], RAEB in transformation [RAEB-t], and overt leukemia evolved from MDS; 14/18 [78%]) compared with tumors ...
An elderly physician with iron deficiency anemia and early stage colon cancer localized in the cecum was treated successfully with laparoscopic right hemicolectomy. Despite treatment, her iron deficiency anemia persisted. Subsequent investigations revealed occult celiac disease that completely resolved with a gluten-free diet alone. Iron deficiency anemia in celiac disease may have multiple cau...
