abstract = {The objective was to evaluate the prognostic and predictive
impact of allelic ratio and insertion site (IS) of internal
tandem duplications (ITDs), as well as concurrent gene
mutations, with regard to postremission therapy in 323
patients with FLT3-ITD-positive acute myeloid leukemia
(AML). Increasing FLT3-ITD allelic ratio (P = .004) and IS
in the tyrosine kinase domain 1 (TKD1, P = .06) were
associated with low complete remission (CR) rates. After
postremission therapy including intensive chemotherapy (n =
121) or autologous hematopoietic stem cell transplantation
(HSCT, n = 17), an allelic ratio ≥ 0.51 was associated
with an unfavorable relapse-free (RFS, P = .0008) and
overall survival (OS, P = .004); after allogeneic HSCT (n =
93), outcome was significantly improved in patients with a
high allelic ratio (RFS, P = .02; OS, P = .03), whereas no
benefit was seen in patients with a low allelic ratio (RFS,
P = .38; OS, P = .64). Multivariable analyses revealed a
high allelic ratio as a predictive factor for the beneficial
effect of allogeneic HSCT; ITD IS in TKD1 remained an
unfavorable factor, whereas no prognostic impact of
concurrent gene mutations was observed. The clinical trials
described herein were previously published or are registered
as follows: AMLHD93 and AMLHD98A, previously published; AML
SG 07-04, ClinicalTrials.gov identifier #NCT00151242.},
