[Continuous infusion therapy with low dose cytosine arabinoside and etoposide in acute myelogenous leukemia patients hardly tolerable for intensive combination chemotherapy].
We evaluated the efficacy of continuous drip infusion therapy with low dose cytosine arabinoside (AraC) and etoposide (VP16) in poor-condition patients with acute myelogenous leukemia (AML). Patients' age ranged from 19 to 85 years with a median of 63 years. Principally they received continuous drip infusion for 14 days with AraC (20 mg/day) and VP16 (50 mg/day). Complete remission (CR) rate was 58.3% (7/12) in untreated cases, 33.3% (2/6) in refractory cases to the standard chemotherapy, and 28.6% (2/7) in relapsed cases. The duration of CR ranged from 1.5 to 20 (+) months (median 8) in untreated group and from 2 to 22 months (median 10) in refractory and relapsed groups. Adverse effects such as gastroenterological symptoms appeared but were tolerable. Although infections due to myelosuppression appeared in 22 of 25 cases, they were well controlled by antibiotics. Chemotherapy-related death was not observed. Although CR rate and CR duration of this therapy were not sufficiently high, the regimen was effective in some patients with refractory or relapsed AML. Further studies are required to establish the efficacy, indication and safety of this treatment.
