Primary Endpoints
the response and complete remission rate with Optimized Standard Protocol.
month +6

Response will be evaluated at each clinic visit. Complete response (CR) was defined as achieving all three peripheral blood count criteria: (1) Hb level up to the normal range; (2) ANC≥1.5×109/L; (3) PLT≥100×109/L. Partial response (PR) was defined as transfusion independent, no longer meeting criteria for severe disease. Persistence of transfusion requirement or death was evidence of no response (NR).

Secondary Endpoints
Relapse rate, sustained response (SR), survival, and clonal evolution to myelodysplasia and acute leukemia.
