ObjectiveTo systematically review the efficacy and safety of different tyrosine kinase inhibitors (TKIs) in the treatment of chronic myelocytic leukemia (CML).MethodsPubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) of nilotinib, dasatinib, flumatinib and imatinib for CML from inception to August, 2020. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; network meta-analysis was then performed using Stata 15.0 software and R 3.4.0 software.ResultsA total of 8 RCTs involving 2 775 patients were included. Compared with other TKIs, flumatinib had higher 3-month early molecular response and 1-year progression free survival, and the incidence of serious side effects was relatively low. Major molecular response and complete cytogenetic response were significantly superior to imatinib, and had the same or similar effects to other second-generation TKIs.ConclusionsCurrent evidence shows that flumartinib in the treatment of CML is obviously superior to imatinib, has the same or similar effect with other second generation TKIs. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusions.
