Kaplan–Meier estimates of OS. Comparisons are shown between the t-APL and de novo APL groups and between patients with and without CR at HCT. There were no significant differences in OS between the t-APL and de novo APL groups, but patients with CR at HCT had significantly better OS than those without CR at HCT (P = 0.004). OS, overall survival; APL, acute promyelocytic leukemia; CR, complete remission; HCT, hematopoietic cell transplantation.
