Complete remission (CR) was defined as the morphological recovery evidenced by less than 5% blasts according to bone marrow biopsy with complete hematological recovery. CR with incomplete count recovery (CRi) was defined as the morphological recovery evidenced by less than 5% blasts according to bone marrow biopsy, but with absolute neutrophil count (ANC) ≤ 1,000/µL or platelets ≤ 100,000/µL. ORR was comprised of CR and CRi. Morphological leukemia-free state (MLFS) was defined as morphological recovery without hematological recovery (ANC ≤ 1,000/µL and platelets ≤ 100,000/µL) [14 (link)]. Transfusion independence was defined as any 8-week period where the patient did not require blood or platelet transfusions. Clinical benefit was characterized by achievement of response (CR, CRi, or MLFS) or transfusion independence.
