FLT3 and acute myeloid leukemia: A total of 141 AML patients, WBC < 100,000/μL (p = 0.004) and wild-type FLT3-ITD (p = 0.047) were associated with significantly longer RFS than those in groups of WBC ≥ 100,000/μL and FLT3-ITD positive AML in the univariate analysis, however, they were not found to be independently significant in multivariate analysis.
