Cording to the historical literature, it is reported that patients with CML-CP take MMR as the therapeutic target, and the acquisition rate of DMR under long-term TKI treatment is 50%. The 2-year success rate of TFR patients was 50%. Therefore, maybe only 25% of patients with CML can successfully stop the drug for a long time. It cannot meet the withdrawal needs of patients with long-term drug survival.\n\nThis study is to design a real-world observational registration study for optimal effect. On the premise of taking DMR as the target decision, through initial treatment intervention, improve the DMR rate, which will promote clinical practice, so as to improve the 2-year TFR rate of cml-cp patients. This study is a multicenter, observational, prospective registry to identify the optimal treatment for achieving TFR in CML patients. In this study, the investigators will assess the deep molecular response after 12 months of treatment and the 2-year treatment-free remission rate (TFR 2y) after drug discontinuation.\n\nEligible participants with CML-CP can be enrolled. The observation period of all participants is at least 60 months, of which the first 36 months is the shortest treatment period, and the last 24 months is the TFR observation period after TKIs (Imatinib\u002FFlumatinib\u002FNilotinb\u002F Dasatinib) withdrawal. During the treatment phase, participants can receive TKIs ± IFN (or other treatments) as first-line\u002Fsecond-line treatment, and the treatment plan will be adjusted according to the molecular response. Patients should accept TKI treatment for at least 3 years or more, and MR4\u002FMR4.5 should achieve at least 2 years before discontinuation.",[56,57],"Chronic Myeloid Leukemia","Treatment-free Remission","NOT_YET_RECRUITING","2022-06-27",{"date":61,"type":62},"2022-07-01","ACTUAL",{"date":64,"type":52},"2022-07-31",{"date":66,"type":52},"2031-10-31",{"name":5,"class":6}]
