Chronic myeloid leukemia-Chronic phase(CML-CP) patients treated with receive effective Tyrosine kinase inhibitor -TKI(including imatinib, dasatinib and nilotinib) for more than 5 years, and patients with BCR/ABLIS continuous negative in the last 18 months were randomly admitted to maintain the original effective TKI by half or stop taking . 2. Q-pcr detected BCR/ABLIS in peripheral blood once every month, once every two months after half a year, and continuously monitored for 12 months. 3.
