We enrolled 21 patients with R/R AML (median age, 42 [range, 30–62] years), who received BHA reinduction therapy (bortezomib, 1.3 mg/m2/day on days 1 and 4; homoharringtonine, 4 mg/m2/day and cytarabine, 1.5 g/m2/day for 5 days)....Overall response and CR/CRi rates in FLT3-mutated R/R-AML reached 66.7% (P=0.03 vs that in FLT3 wild-type R/R AML).
