Acute myeloid leukemia (AML) has posed significant therapeutic challenges to pediatric oncologists. Despite intensive therapy, half of the children with AML relapse and die from their disease. Efforts to identify risk factors in AML are directed toward defining populations who may benefit from alternative therapies. Patients at lower risk for relapse may benefit from treatment de-escalation, sp...
DEK is important in regulating cellular processes including proliferation, differentiation and maintenance of stem cell phenotype. The translocation t(6;9) in Acute Myeloid Leukemia (AML), which fuses DEK with NUP214, confers a poor prognosis and a higher risk of relapse. The over-expression of DEK in AML has been reported, but different studies have shown diminished levels in pediatric and pro...
Acute myeloid leukemia (AML) is a heterogeneous disease characterized by the presence of different collaborating cytogenetic and molecular aberrations that are associated with treatment response. Approximately 20% of pediatric AML patients are classified as cytogenetically normal AML (CN-AML). In the past decade, new prognostic relevant aberrations have been identified in CNAML, such as NPM1, W...
We previously demonstrated that outcome of pediatric 11q23/MLL-rearranged AML depends on the translocation partner (TP). In this multicenter international study on 733 children with 11q23/MLL-rearranged AML, we further analyzed which additional cytogenetic aberrations (ACA) had prognostic significance. ACAs occurred in 344 (47%) of 733 and were associated with unfavorable outcome (5-year overal...
PURPOSE Apoptosis-related proteins are important molecules for predicting chemotherapy response and prognosis in adult acute myeloid leukemia (AML). However, data on the expression and prognostic impact of these molecules in childhood AML are rare. EXPERIMENTAL DESIGN Using flow cytometry and Western blot analysis, we, therefore, investigated 45 leukemic cell samples from children with de nov...
Retroviral insertion mutagenesis is considered a powerful tool to identify cancer genes in mice, but its significance for human cancer has remained elusive. Moreover, it has recently been debated whether common virus integrations are always a hallmark of tumor cells and contribute to the oncogenic process. Acute myeloid leukemia (AML) is a heterogeneous disease with a variable response to treat...

Although virtually all pediatric patients with acute myeloid leukemia (AML) achieve a complete remission after initial induction therapy, 30%-40% of patients will encounter a relapse and have a dismal prognosis. To prevent relapses, personalized treatment strategies are currently being developed, which target specific molecular aberrations. To determine relevance of established AML type I/II mu...
Acute myeloid leukemia (AML) is a type of poor prognosis hematological malignancies characterized by heterogeneous clonal expansion of myeloid progenitors. Leukemic stem cells are thought to form the majority of a cell population in minimal residual diseases (MRDs) which are resistant to current chemotherapeutic regimens and mediate disease relapse. Current therapeutic vaccine strategies have d...
Acute myeloid leukemia (AML) is a clonal disorder affecting pluripotent stem cells and is characterized by ineffective hematopoiesis. Most AML patients harbor cytogenetic and molecular defects that identify entities with peculiar biologic and clinical data and distinct therapeutic responses. Approximately 50%–60% of de novo AML and 80%–95% of secondary AML patients display chromosomal aberratio...
