title: Mitoxantrone, etoposide and intermediate-dose Ara-C (MEC): an effective regimen for poor risk acute myeloid leukemia.
abstract: A total of 74 patients with poor risk AML (median age 36.7 years, range 4.5-60.6) received a single course of a regimen including mitoxantrone (6 mg/m2 intravenous bolus daily, days 1 to 6), etoposide (80 mg/m2 intravenous over 1 h, daily, days 1 to 6) and intermediate-dose Ara-C (1 g/m2 over 6 h, daily days 1 to 6). 28 patients had failed initial remission induction with daunorubicin and conventional doses of Ara-C, 16 patients had secondary AML and 30 patients had relapsed from initial remission (five within six months, 15 over six months and ten after autologous or allogeneic bone marrow transplantation). Overall 41/74 patients (55%) achieved complete remission, 26 (35%) had resistant disease and seven (10%) died of infection during marrow hypoplasia. A 4-day course of the same regimen was given as consolidation to patients in complete remission. Subsequent antileukemic therapy was individualized. Profound myelosuppression and pancytopenia were universal resulting in fever or documented infections in almost 100% of patient; major hemorrhagic complications occurred in 39% of patients. Extrahematologic toxicity was mild to moderate consisting mostly of nausea and vomiting, oral mucositis and transient liver and cardiac dysfunction. We conclude that the MEC combination chemotherapy program seems to be an effective antileukemic regimen for secondary and advanced AML, with acceptable toxicity.
