How were CR, CRp, and PR defined?
Complete remission (CR) was defined as no circulating blasts or extramedullary disease, <5% bone marrow blasts, recovery of peripheral blood counts (platelet count >100 x 109/L and absolute neutrophil count [ANC] > 1.0 x 109/L). Complete remission without platelet recovery (CRp) was defined as meeting all criteria of CR except for recovery of platelet counts to >100 x 109/L. Partial response (PR) was defined as no circulating blasts, ≥5% and ≤25% bone marrow blasts, and the appearance of normal progenitor cells or M1 bone marrow that did not qualify for CR or CRp.
