Mutations of nicotinamide adenine dinucleotide phosphate-dependent isocitrate dehydrogenase gene (IDH1) have been identified in patients with gliomas. Recent genome-wide screening also revealed IDH1 mutation as a recurrent event in acute myeloid leukemia (AML), but its clinical implications in AML are largely unknown. We analyzed 493 adult Chinese AML(More)
The studies concerning clinical implications of TET2 mutation in patients with primary acute myeloid leukemia (AML) are scarce. We analyzed TET2 mutation in 486 adult patients with primary AML. TET2 mutation occurred in 13.2% of our patients and was closely associated with older age, higher white blood cell and blast counts, lower platelet numbers, normal(More)
Mutations in the additional sex comb-like 1 (ASXL1) gene were recently shown in various myeloid malignancies, but they have not been comprehensively investigated in acute myeloid leukemia (AML). In this study, we analyzed ASXL1 mutations in exon 12 in 501 adults with de novo AML. ASXL1 mutations were detected in 54 patients (10.8%), 8.9% among those with(More)
DNMT3A mutations are associated with poor prognosis in acute myeloid leukemia (AML), but the stability of this mutation during the clinical course remains unclear. In the present study of 500 patients with de novo AML, DNMT3A mutations were identified in 14% of total patients and in 22.9% of AML patients with normal karyotype. DNMT3A mutations were(More)
Recurrent somatic mutation of SRSF2, one of the RNA splicing machinery genes, has been identified in a substantial proportion of patients with myelodysplastic syndrome (MDS). However, the clinical and biologic characteristics of MDS with this mutation remain to be addressed. In this study, 34 (14.6%) of the 233 MDS patients were found to have SRSF2(More)
Mutations of the SET binding protein 1 (SETBP1) gene have been identified in patients with myeloid neoplasms, but the clinical relevance of this mutation and its association with other gene mutations in myelodysplastic syndrome (MDS) and the stability during disease progression remains unclear. Mutations in SETBP1 gene at exon 4 were analyzed by polymerase(More)
Current information about clinical significance of IDH mutations in myelodysplastic syndromes (MDS), their association with other genetic alterations and the stability during disease progression is limited. In this study, IDH mutations were identified in 4.6% of 477 patients with MDS based on the FAB classification and in 2.2 % of 368 patients based on the(More)
The revised International Prognostic Scoring System (IPSS-R) was recently developed to better assess the clinical outcome of adult patients with myelodysplastic syndrome (MDS). In this study, we aimed to investigate the prognostic impact of this new risk model on 555 MDS patients in Taiwan. Generally, the IPSS-R could discriminate MDS patients regarding(More)
CXC chemokine receptor 4 (CXCR4) is an essential regulator for homing and maintenance of hematopoietic stem cells within the bone marrow niches. Analysis of clinical implications of bone marrow CXCR4 expression in patients with acute myeloid leukemia showed not only higher CXCR4 expression was an independent poor prognostic factor, irrespective of age,(More)
We aimed to analyze clinical impacts of the U2AF1 mutation on patients with myelodysplastic syndrome (MDS) and its stability during disease progression. We checked mutation status of the U2AF1 by direct sequencing in 478 de novo MDS patients and correlated with the clinical characteristics and outcomes. We also sequentially analyzed the U2AF1 mutation in(More)
