Acute myelogenous leukaemia in older patients at St Bartholomew's Hospital: outcome with mitoxantrone and cytarabine.
Elderly patients (age >60 years) with AML who are selected for curative treatment frequently receive anthracycline/cytarabine containing regimens. The anthracendione mitoxantrone (MTN) in combination with cytarabine (Ara-C) produces comparable complete remission rates to other regimens and may be less toxic. Over a 12 year period, 75 patients (median age 67 years, range 60-83 years) referred with newly diagnosed AML were treated with MTN and ara-C. MTN was administered at 12 mg/m(2)/day intravenously for three days in the first 26 patients, and 10 mg/m(2)/day intravenously for five days in a subsequent 49 patients. Ara-C was administered at a dose of 100 mg/m(2) twice daily intravenously for seven days. Complete remission (CR) was achieved in 34 out of 75 patients (45%). The median disease-free survival overall was 7.5 months (one month to nine and a half years). The median survival was one year for patients in whom CR was achieved, compared to four months in patients whom treatment failed (P=0.001). Age alone was predictive of achievement of CR, whilst presentation karyotype, serum LDH and patient age correlated with overall survival. These results confirm that although elderly patients have a poor outcome, prognostic factors can be identified that influence treatment outcome in this important group of patients.
