[Preliminary treatment results of relapsed or refractory acute leukemia using two and three drug regimens]

36 patients with relapsed (29) or refractory (7) acute lymphoblastic or nonlymphoblastic leukaemia received regimens employing 1-3 courses of mitoxantrone (or idarubicin), intermediate doses of cytarabine and etoposide. Complete remission (CR) was achieved in 30% of patients (5/15 ALL, 6/21 AML, 5 cases of refractory and 6 of relapsed leukaemia). Duration of CR was 3-6+ months (3 patients are still alive). Toxicity of the treatment was acceptable, however 5 patients with severe granulocytopenia died from sepsis.
