Sensitive measurement of quantity dynamics of FLT3 internal tandem duplication at early time points provides prognostic information.
BACKGROUND The level of minimal residual disease (MRD) in acute myeloid leukemia (AML) at early time points (TPs) may be an important prognostic factor. Although internal tandem duplication of FLT3 (FLT3-ITD) as an MRD marker has been questioned for its instability based on semi-quantitative methods, we hypothesized that FLT3-ITD dynamics measured by sensitive quantitative real-time PCR at earl...
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 کاملIncidence 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 کاملPrevalence and prognostic significance of Flt3 internal tandem duplication in pediatric acute myeloid leukemia.
The Flt3 gene encodes a tyrosine kinase receptor that regulates proliferation and differentiation of hematopoietic stem cells. An internal tandem duplication of the Flt3 gene (Flt3/ITD) has been reported in acute myelogenous leukemia (AML) and may be associated with poor prognosis. We analyzed diagnostic bone marrow specimens from 91 pediatric patients with AML treated on Children's Cancer Grou...
متن کاملPrognostic significance and detection of the internal tandem duplication of the FLT3 gene in acute myeloid leukemia.
The FMS-like tyrosine kinase-3 (FLT3), which belongs to the class III receptor tyrosine kinase family, expressed by immature hematopoietic cells, plays an important role in the proliferation, differentiation and survival of stem cells. The activating mutations of FLT3 gene have been reported to be of prognostic significance. The most common somatic alteration of the FLT3 gene is the Internal Ta...
