Finally, cotreatment with LBH589 and 17-AAG also induced more apoptosis of IM-resistant primary CML-BC and acute myeloid leukemia (AML) cells (with activating mutation of FLT-3) than treatment with either agent alone.
These results provide pre-clinical and clinical evidence for an effective combinatorial treatment strategy targeting XPO1 and FLT3 in <i>FLT3</i>- mutated acute myeloid leukemias.
Abstract Several molecular markers, such as NPM1, FLT3 and CEBPA, have been incorporated into both the World Health Organization and European LeukemiaNet classifications as routine assessments for the diagnosis and evaluation of prognostic significance in acute myeloid leukemia (AML).
Our data suggest that sorafenib therapy is associated with improved outcomes for FLT3-ITD AML relapsing after allo-HSCT, and whether sorafenib combined with chemotherapy followed by DLI reveals an optimal efficacy merits further study.
The FLT3 internal tandem duplication (ITD) and the D835 activating mutation in the tyrosine kinase domain (TKD) were analyzed by polymerase chain reaction (PCR) in the genomic DNA of Korean patients with AML at diagnosis and during follow-up.
The combination of midostaurin or gilteritinib with venetoclax potently and synergistically induces apoptosis in FLT3-ITD AML cell lines and primary patient samples.
Thus, FLT3-ITD confers a resistance to the proteasome inhibitors on AML cells by protecting the mTORC1/Mcl-1 pathway through the STAT5/Pim axis, and inhibition of these signaling events remarkably enhances the therapeutic efficacy.
A tandem duplication of exon 11 of FLT3 was harbored by two of 58 (3%) patients with MDS and five of 34 (15%) with overt leukemia, including MDS-derived leukemia, AML/TMDS and therapy-related leukemia.
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.
