Abstract:
[Objective] To retrospectively analyze the outcome of unrelated umbilical cord blood transplantation in the treatment of aggressive-phase chronic myeloid leukemia.[Methods] Fourteen consecutive patients with aggressive-phase chronic myeloid leukemia were treated with unrelated umbilical cord blood transplantation,thirteen patients were treated with myeloablative unrelated CBT and one patients were treated with nonmyeloablative unrelated CBT.All patients received standard cyclosporine A (CsA) and mycophenolate mofetil(MMF) as a graft-versus-host disease (GVHD) prophylaxis.[Results] 14 patients were all successfully engrafted.The median times for their neutrophil returning to ≥0.5×109/L and for platelet returning to ≥20×109/L were 22.8 days and 37.8 days,respectively.Acute GVHD occurred in 10 of 13 evaluable patients.The grading of acute GVHD was gradeⅡ-Ⅳin 6 patients(46.2 %).Chronic GVHD occurred in 7 of 11 evaluable patients(63.6%).Relapse occurred in 2 of 15 patients,lextramedullary relapse was included.9 of 14 patients were alive and event-free after CBT.The probability of OS rate at 5 years was 64.3 %,the probability of DFS rate at 5 years was 5,7.1%.[Conclusion]Unrelated umbilical cord blood transplantation is effective in the treatment of aggressive-phase chronic myeloid leukemia.
