PURPOSE The transcription factor CCAAT/enhancer binding protein alpha, encoded by the CEBPA, is crucial for the differentiation of immature granulocytes. Mutation of the CEBPA may play an important role in leukemogenesis and prognosis. We sought to characterize the CEBPA mutation in acute myeloid leukemia (AML) and to clarify if there is a distinct(More)
PURPOSE To investigate the possible prognostic factors of survival outcomes in patients with granulocytic sarcoma (GS). METHODS We retrospectively investigated the prognostic factors determining survival in 24 patients with GS using Kaplan-Meier survival analysis followed by log rank tests. We evaluated gender, age, location, GS antedating leukemia,(More)
CD4(+) CD25(+) regulatory T cells (Tregs) are critical in maintaining self-tolerance and preventing organ-specific autoimmunity. Their role in paediatric systemic lupus erythematosus (SLE), an autoimmune disease characterized by inappropriate regulation of hyperactivated B and T cells, has not been clearly defined. Using flow cytometry to determine cell(More)
Nucleophosmin (NPM) mutations have been found in a significant proportion of adults with de novo acute myeloid leukemia (AML), especially in those of a normal karyotype. These results provide a basis for studies of the pathogenesis in this specific subgroup of AML. In this study, NPM mutations were analyzed in 173 Chinese patients of de novo AML, including(More)
Despite current risk-directed therapy, approximately 15-20% of pediatric patients with acute lymphoblastic leukemia (ALL) have relapses. Recent genome-wide analyses have identified that an alteration of IKZF1 is associated with very poor outcomes in B-cell progenitor ALL. In this study, we determined the prognostic significance of IKZF1 deletions in(More)
Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) were demonstrated to have important implications in the progression and invasiveness of many malignant disorders. In contrast, the biological significance of these molecules in human leukaemias is not clear. We determined the levels of MMP-2, MMP-9, TIMP-1 and TIMP-2 in the(More)
BACKGROUND The DNA repair gene XRCC4, a member of the protein family involved in non-homologous end-joining repair pathway, plays a major role in repairing DNA double-strand breaks. XRCC4 is important in maintaining the overall genome stability, and it is also thought to play a key role in human carcinogenesis. We investigated some novel polymorphic(More)
Studies have found lower risk of childhood cancer among Asian children. We aim to characterize the recent incidence and incidence-trend of childhood cancer in Taiwan after the National Health Insurance program was launched in March 1995. Data were extracted from the Taiwan Cancer Registry, a population-based database established in 1979. Cases diagnosed at(More)
Aberrant expression of the simple mucin-type carbohydrate antigens such as Tn antigen is associated with malignant transformation and cancer progression. N-acetylgalactosaminyltransferase 2 (GALNT2), one of the enzymes that mediate the initial step of mucin-type O-glycosylation, is responsible for forming Tn antigen. GALNT2 is expressed differentially in(More)
Juvenile myelomonocytic leukemia (JMML) is a rare clonal myeloproliferative disease in young childhood. Hematopoietic stem cell transplantation (HSCT) is the only way to cure the disease, but relapse after HSCT remains a major cause of treatment failure. A 5-year-old girl with JMML, who had experienced a relapse after the first transplant, did not respond(More)
