ABSTRACT
Objective To study the clinical outcome of patients with fns-like tyrosine kinase-3internal tandem duplication (FLT3-ITD) positive acute myeloid leukemia (AML) treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT) and to explore the potential prognostic factors to patients' survival including transplant types or disease status.Methods A total of 314 AML patients in our center from October 2006 to October 2012 were retrospectively analyzed,among whom,54 patients were defined with FLT3-ITD positive.Survival rates and treatment-related mortality were further analyzed.Results For all 54 FLT3-ITD positive patients,the 3-year overall survival (3-OS) rate was 56% and 3-year leukemia-free survival (3-LFS) rate was 47%.The outcome of haplo-identical HSCT was similar as that of sibling donors(3-OS rate:60% vs 54% ; 3-LFS rate:54% vs 45%,respectively).There were 47 patients who received transplantation in first complete remission(CR1).The other 7 patients were of disease relapse or in CR2 before transplantation.Not surprisingly,patients in CR1 had better prognosis than those in nonCR1.Conclusions Allo-HSCT is an effective treatment for AML patients with FLT3-ITD positive mutation.The survival outcome of haplo-identical HSCT was comparable with that of sibling donors.Relapse of AML was the dominant factor related to the mortality of FLT3-ITD positive AML patients after allo-HSCT.
