ABSTRACT
To compare the efficacy and toxicity of a novel regimen called FBA, consisting of fludarabine, busulfan, and cytarabine, with the standard BuCy2 regimen for younger adult patients with acute myeloid leukemia, we conducted a prospective randomized phase II study. Patients in complete remission were randomly assigned to receive either the FBA (n = 56) or the BuCy2 regimen (n = 55). The difference in 100-day transplant-related mortality (TRM) was not statistically significant between the two arms (1.79% for FBA versus 5.45% for BuCy2, P = 0.260), as were the cumulative incidences of relapse, TRM, overall survival (OS) and event-free survival (EFS) at 3 years. However, the 100-day cumulative incidences of grades II-IV and III-IV acute graft-versus-host disease (aGVHD) were lower in the FBA group [(8.93% versus 21.86%, P = 0.032) (1.79% versus 9.09%, P = 0.025)]. The 3-year GVHD and relapse-free survival (GRFS) was 31.20% for the FBA group and 14.96% for the BuCy2 group (P = 0.004). The incidences of diarrhea and severe oral mucositis within the first 30 days post-transplantation were lower in the FBA group [(28.57% versus 65.45%; P < 0.001) (51.79% versus 70.91%; P = 0.039)]. In conclusion, allogenic transplantation with the FBA regimen achieved similar TRM, relapse rate, OS and EFS, as that with the BuCy2 regimen but with less frequent and less severe complications in early stage after transplantation and a trend toward higher GRFS.
