Abstract: Objective To investigate the effect of postremission consolidation therapy with intermedium-dose cytarabine (MDAC) in elderly patients with acute myelogenous leukemia (AML). Methods Clinical data of 61 elderly AML patients (except M3) in postremission who achieved complete remission (CR) in two period of remission induction program were retrospectively analyzed. Results There were 26 cases in MDAC group and 35 cases in standard-dose cytarabine (SDAC) group. In MDAC group and SDAC group, the relapse free survival (RFS) time were 42.7 months and 16.0 months respectively (P= 0.002), the overall survival (OS) time were 44.6 months and 18.2 months respectively (P= 0.004), and the cumulative relapse frequencies rates were 26.9 % (7/26) and 54.3 % (19/35) respectively (x 2= 4.567, P= 0.033). However, 3 years OS rate of the two groups were 23.1%(6/26) and 8.6%(3/35) (x 2=2.496, P=0.114) , and there was no significant difference in the incidence of adverse reactions between the two groups (all P > 0.05). Conclusion MDAC could improve RFS and OS for the elderly AML patients in postremission who received CR in the early stage, and the incidence of adverse reactions is similar to that of SDAC.
