To evaluate internal tandem duplication (ITD) insertion sites and length as well as their clinical impact in younger adult patients with FLT3-ITD-positive acute myeloid leukemia (AML), sequencing after DNA-based amplification was performed in diagnostic samples from 241 FLT3-ITD-mutated patients. All patients were treated on 3 German-Austrian AML Study Group protocols. Thirty-four of the 241 patients had more than 1 ITD, leading to a total of 282 ITDs; the median ITD length was 48 nucleotides (range, 15-180 nucleotides). ITD integration sites were categorized according to functional regions of the FLT3 receptor: juxtamembrane domain (JMD), n = 148; JMD hinge region, n = 48; beta1-sheet of the tyrosine kinase domain-1 (TKD1), n = 73; remaining TKD1 region, n = 13. ITD length was strongly correlated with functional regions (P < .001). In multivariable analyses, ITD integration site in the beta1-sheet was identified as an unfavorable prognostic factor for achievement of a complete remission (odds ratio, 0.22; P = .01), relapse-free survival (hazard ratio, 1.86; P < .001), and overall survival (hazard ratio, 1.59; P = .008). ITD insertion site in the beta1-sheet appears to be an important unfavorable prognostic factor in young adult patients with FLT3-ITD-positive AML. The clinical trials described herein have been registered as follows: AML HD93 (already published in 2003), AML HD98A (NCT00146120; http://www.ClinicalTrials.gov), and AMLSG 07-04 (NCT00151242; http://www.ClinicalTrials.gov).
