Assessment
Primary outcomes
The CMR maintenance rate at 1 year after a stop of dasatinib administration in patient who have maintained CMR for 2 years in treatment of TKIs.
Key secondary outcomes
* The CMR maintenance rate at 2 and 3 years ,and relapse free survival (RFS), event free survival (EFS) , progression free survival (PFS) and overall survival (OS) at 1, 2 and 3 years after a stop of dasatinib administration in patient who have maintained CMR for 2 years after a start of clinical study.
*The 2 year CMR maintenance rate of patients at 24 months after the start of study.
* The relationship between the time to CMR or MMR achievement and CMR maintenance rate at 1, 2 and 3 year after the stop of administration.
* The search for predictive factor of a stop of dasatinib administration.
* The relationship between the CMR maintenance rate and the following factors.
- age, sex, Sokal score
- treatment duration of TKIs
- Total duration of BCR-ABL negative conversion to pre-registration.
- LGL incidence
- total treatment period and total dose of dasatinib
* CMR achievement rate after re-administration in recurrent case after stop of dasatinib administration.
* Safety
