Prognostic significance of nucleophosmin mutations and FLT3 internal tandem duplication in adult patients with cytogenetically normal acute myeloid leukemia
BACKGROUND Nucleophosmin (NPM1) gene and fms-like tyrosine kinase 3 gene-internal tandem duplication (FLT3-ITD) mutations are the most frequent mutations in patients with cytogenetically normal (CN)-AML. We analyzed the prognostic impact of these mutations and their interactions in adults with CN-AML. METHODS NPM1 mutation (NPM1mut) and FLT3-ITD mutation (FLT3-ITD+) were analyzed by GeneScan ...
متن کاملSize of FLT3 internal tandem duplication has prognostic significance in patients with acute myeloid leukemia.
FLT3 internal tandem duplications (FLT3/ITDs) in the juxtamembrane domain are found in approximately 25% of acute myeloid leukemia (AML) patients, ranging in size from 3 to hundreds of nucleotides. We examined whether the sizes of FLT3/ITDs were associated with clinical outcomes in 151 AML patients enrolled in Southwest Oncology Group studies: S9333 and S9500. FLT3/ITDs were identified in 32% o...
متن کاملCharacteristics and Prognosis of Adult Acute Myeloid Leukemia with Internal Tandem Duplication in the FLT3 Gene.
OBJECTIVES Constitutive activation of the fms-like tyrosine kinase 3 (FLT3) receptor by internal tandem duplication (ITD) of the juxtamembrane region has been described in patients with acute myeloid leukemia. FLT3/ITDs are present in about 20-30% of all acute myeloid leukemia cases. It has been shown that the mutation is correlated with worse prognosis. However, none of the previous studies in...
متن کاملPrognostic significance of FLT3 internal tandem duplication in egyptian patients with acute myeloid leukemia with normal or favorable risk cytogenetics.
Internal tandem duplication (ITD) of the FLT3 gene (FLT3/ITD) has been linked to poor outcome in acute myeloid leukemia (AML). However, the prognostic value of FLT3/ITD in various cytogenetic risk groups is still a matter of debate. The aim of this study was to evaluate the prognostic significance of FLT3/ITD in patients with de novo AML and normal or favorable risk cytogenetics (NFC-AML). Bloo...
متن کاملImmunophenotypic findings in acute myeloid leukemia with FLT3 internal tandem duplication.
BACKGROUND AND OBJECTIVES The biological characteristics and the prognostic significance of the internal tandem duplication of the FLT3 (FLT3/ITD) were investigated in a series of de novo acute myeloid leukemia (AML) patients. One hundred and fifty-six adult patients with AML were included in the study. FLT3/ITD was detected in 41 (26%) patients (FLT3/ITD(+)). DESIGN AND METHODS The main diff...
