In the tyrosine kinase inhibitor (TKI) era, imatinib is the first-line therapy for patients with chronic myeloid leukemia (CML) in chronic or accelerated phase. Although second-generation TKIs (TKI2), including dasatinib and nilotinib, are appropriate treatment regimens for patients with disease that progressed to accelerated phase following imatinib therapy, allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only curative therapy. This study retrospectively analyzed the efficacy of TKI2 and HSCT for treatment of CML in accelerated phase. Ninety-three patients with CML registered in the Chinese CML alliance database from February 2001 to February 2014 were enrolled and divided into the TKI2 (n?=?33) and allo-HSCT (n?=?60) groups. In the TKI2 group, 26 and 7 patients received nilotinib and dasatinib, respectively, as initial TKI2 and 11 patients transferred to the alternative TKI2 after failure to one TKI2. In the allo-HSCT group, 22 (36.7%), 35 (58.3%), and 3 (10%) patients underwent allo-HSCT from an HLA-matched sibling donor, HLA mismatched/haploidentical donor, and unrelated donor, respectively. All patients in the HSCT group were engrafted. Overall, 69.7%, 48.5%, and 45.5% of patients presented hematological, cytogenetic, and major molecular responses, respectively, to at least one of TKI2. All 60 patients (100%) achieved CHR and cytogenetic response in the HSCT group. Patients in the TKI2 group exhibited lower 5-year overall survival rate (42.9% vs. 86.4%, P = 0.002), 5-year event-free survival rate (14.3% vs. 76.1%, P<0.001), and 5-year progression-free survival (28.6% vs. 78.1%, P<0.001) than those in the allo-HSCT group. Multivariate analysis showed that male sex and TKI2therapy were predictors of poor overall survival, whereas hemoglobin<100 g/L and TKI2 therapy were predictors of poor event-free survival and progression-free survival. These results indicated that allo-HSCT may be superior to nilotinib and dasatinib for adult patients with CML in accelerated phase.
