Size 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 کاملInvestigations of FLT3 internal tandem duplications in patients with acute myeloid leukaemia
In acute myeloid leukaemia (AML), further prognostic determinants are required in addition to cytogenetics to predict patients at increased risk of relapse. Recent studies have indicated an internal tandem duplication (ITD) in the FLT3 gene may adversely affect clinical outcome. The studies reported in this thesis evaluated the impact of a FLT3/ITD on outcome in 854 patients treated in UK MRC A...
متن کاملFlt3 internal tandem duplication and P-glycoprotein functionality in 171 patients with acute myeloid leukemia.
PURPOSE Patients with adult acute myeloid leukemia (AML) with intermediate cytogenetics remain a heterogeneous group with highly variable individual prognoses. New molecular markers could help to refine cytogenetic stratification. EXPERIMENTAL DESIGN We assessed P-glycoprotein (Pgp) activity and Flt3 internal tandem duplication (ITD+) because of their known prognostic value and because they m...
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 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...
