Incidence and prognostic value of FLT3 internal tandem duplication and D835 mutations in acute myeloid leukemia.
BACKGROUND AND OBJECTIVES Cytogenetics is the most important prognostic factor in acute myeloid leukemia (AML). However, a high proportion of patients show normal or intermediate-risk karyotypes. In these patients, other determinants could help to identify those with a higher risk of relapse. Recently, internal tandem duplications (ITD) and D835 mutations in FLT3 tyrosine kinase receptor have b...
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 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 کاملA FLT3 tyrosine kinase inhibitor is selectively cytotoxic to acute myeloid leukemia blasts harboring FLT3 internal tandem duplication mutations.
Internal tandem duplication (ITD) mutations of the receptor tyrosine kinase FLT3 have been found in 20% to 30% of patients with acute myeloid leukemia (AML). These mutations constitutively activate the receptor and appear to be associated with a poor prognosis. Recent evidence that this constitutive activation is leukemogenic renders this receptor a potential target for specific therapy. In thi...
متن کاملFLT3 internal tandem duplication mutations are rare in agnogenic myeloid metaplasia.
We were interested in the recent report by Kelly et al1 that FLT3 internal tandem duplication (FLT3-ITD) mutations, while sufficient to induce a chronic myeloproliferative disease in a murine bone marrow transplant (BMT) assay, were not sufficient to induce an acute myeloid leukemia (AML) phenotype. These data suggest that FLT3-ITDs may require additional cooperating mutations to generate the A...
