Clinical analysis of HAA induction regimen for newly diagnosed and refractory relapsed acute myeloid leukemia / 白血病·淋巴瘤

ABSTRACT

Objective To analyze the efficacy and safety of HAA induction regimen consisted of homoharringtonine (HHT),cytarabine (Ara-C) and aclacinomycin (ACM) in naive and refractory relapsed acute myeloid leukemia.Methods Data from 66 acute myeloid leukemia (AML) cases hospitalized and treated with HAA induction regimen was analyzed retrospectively.Results 45 of the 66 cases suffered from naive AML,and 21 were refractory relapsed.HAA efficacy in naive AML was evaluated in 41 cases with 36 in complete remission (CR) and 1 in partial remission (PR).The efficiency of HAA induction regimen was 90.2 ％ (37/41)in naive AML group and 42.9 ％ (9/21) in refractory relapsed group,respectively.There were no differences (P ＞ 0.05) when considering patient' s gender,age,disease subtype and white blood cell count at onset.14 patients in CR with naive AML were followed-up for a median time of 9 months (2-17 months),and 5 cases relapsed (35.7 ％) in a range of 2-8 months.The median myelosuppression period was 14 days (3-23 days).Nausea and vomiting [20 ％ (13/66)] were the major side effects of HAA regimen,and the other side effects were abdominal pain and diarrhea [9 ％ (6/66).After chemotherapy,53 ％ (35/66) of the cases experienced infection/fever due to neutropenia.Other severe non-hematological side effects did not occur.Conclusion HAA regimen may be an ideal choice for the induction chemotherapy of naive and relapsed refractory AML.
