Abstract

OBJECTIVE:

To compare the efficacy and toxicities of combining homoharringtonine (HHT)┬▒daunorubicin (DNR) with all-trans-retinoic acid (ATRA) based therapy and DNR plus ATRA based therapy in newly diagnosed low/intermediate risk acute promyelocytic leukemia (APL).

METHODS:

A total of 96 newly diagnosed patients with APL were randomized to HHT group, DNR group and HHT+ DNR group prospectively. The complete remission (CR) rate, the overall survival (OS) and event-free survival (EFS) of three groups were analyzed.

RESULTS:

There were 31 patients in HHT group, 33 patients in DNR group and 32 patients in HHT+ DNR group. The baseline characteristics of three groups were similar. No patient died during induction therapy. The morphologic CR rate was 100.0%. The median time to peak WBC counts in HHT+DNR group (4 days, range: 1-23 days) was significantly shorter than that in HHT group (9 days, range: 1-27 days) (P=0.008) and DNR group (7 days, range: 1-27 days) (P=0.240). There was no difference among three groups about the incidence of differentiation syndrome, the median interval to achieve CR, peak WBC counts and transfusions (P >0.05). All patients achieved complete molecular remission (CMR) during consolidation therapy. The interval to achieve CMR was no significantly difference among three groups (P >0.05). The 3-year OS rates for HHT group, DNR group and HHT+DNR group were 95.0%, 100.0% and 91.0%, respectively (P=0.595). The 3-year EFS rates for three groups were 93.0%, 90.0% and 85.0% (P=0.382). No difference was found in the incidence of adverse events among three groups (P >0.05).

CONCLUSIONS:

Similar to DNR plus ATRA based therapy, HHT plus ATRA based induction and consolidation therapy should be one of highly-efficient treatment options for newly diagnosed APL. Clinical trial registration Chinese Clinical Trial Registry, ChiCTR-TRC-12002628.
