Flt3-ITD+ acute myeloid leukemia (AML) blasts from patients invariably generated early AG1295-sensitive CAs in MS-5 cocultures, further validating the phenotype observed in transduced CD34+ cells.
FLT3 mutations demonstrate no further prognostic impact in patients with normal karyotype AML in first CR treated with high-dose chemotherapy and auto-PBSCT.
FLT3 mutation status of 630 children with de novo acute myeloid leukemia (AML) treated on CCG-2941 and -2961 was determined, and ITD-AR was calculated for patients with FLT3/ITD.
Flt3/ITD and Pgp activity are independent and additive prognostic factors which provide a powerful risk classification that can be routinely used to stratify the treatment of patients with intermediate cytogenetic AML.
FMS-like tyrosine kinase-3 (FLT3) is a new therapeutic target for acute myelocytic leukemia (AML), because FLT3 mutations are the most common genetic alterations in AML and are directly related to leukemogenesis.
FLT3 tyrosine kinase domain mutations are biologically distinct from and have a significantly more favorable prognosis than FLT3 internal tandem duplications in patients with acute myeloid leukemia.
FLT3 internal tandem duplication (FLT3/ITD) is a common somatic mutation in acute myeloid leukemia (AML) with significant variation in the position, length, and number of duplications of the FLT3 gene.
FLT3 internal tandem duplication mutant levels >50%, indicative of bi-allelic disease in some cells, are associated with a particularly poor prognosis in acute myeloid leukaemia; lower levels have an intermediate prognosis relative to wild-type FLT3.
