We evaluated these physical characteristics in FLT3/ITD-positive patients who were treated on CCG-2941/2961 and correlated them with clinical outcome. Fiftynine of 77 FLT3/ITD-positive patients (77%) had a single ITD, 16 (21%) had 2 ITDs, and 2 (3%) had 3 ITDs. The length of the duplicated region varied from 6 to 51 amino acids, and in all cases amino acid residues Y591–Y597 were duplicated. Structural analysis demonstrated that Y591–Y597 encodes the switch and zipper regions of the juxtamembrane domain of FLT3. In addition, 24 of 77 patients (31%) had duplication of the critical STAT5 docking sites Y589/591. Patients with longer ITDs had a worse relapse-free survival (19% vs 51%, P = .035), while the presence of more than 1 ITD was not clinically significant. Physical characteristics including the length of FLT3/ITD may influence FLT3 activation state by altering its structure and may impact response to therapy.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320722370055","@type":"Researcher","foaf:name":[{"@value":"Soheil Meshinchi"}],"jpcoar:affiliationName":[{"@value":"Clinical Research Division, Fred Hutchinson Cancer Research Center, and"},{"@value":"Department of Pediatrics, University of Washington Medical Center, Seattle;"},{"@value":"Children's Oncology Group, Arcadia, CA;"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320722370048","@type":"Researcher","foaf:name":[{"@value":"Derek L.
