Summary Thirty-four patients with acute myeloid leukemia (AML) in complete remission (CR), 30 of them aged over 60, received maintenance therapy scheduling four courses of low-dose cytarabine (LDA) 20 mg/m2/day in two subcutaneous injections for 3 weeks every 6 weeks. Each course was stopped when hematologic toxicity occurred, and doses of LDA were subsequently reduced by 50% for the following courses. During the first course of LDA, 15 patients needed blood and four patients platelet transfusions. Overall, 28 patients received four courses of LDA: 11 did not require any dose reduction, while 14 required one dose reduction and three neeeded two successive dose reductions. Two patients were hospitalized during maintenance. Median disease-free survival (DFS) is 308 days, with 16% of patients surviving at 5 years. Seven patients relapsed during the 168 days of maintenance, while ten of the 27 patients remaining at risk on day 169 relapsed during the 168 days following maintenance. We conclude that in AML in CR, the maximal dose of LDA tolerated by ambulatory patients is 10 mg/m2/day for 3 weeks. LDA seemed to delay relapse; however, precise assessment of the efficacy of this approach would require a randomized trial.
