Objective To determine the plasma concentration of cytarabine(Ara-C) in children with leukemia and obtain dynamics parameters, and investigate the relationship between the parameters and clinical effect in order to provide the basis for optimization of Ara-C application. Methods Using highperformance liquid chromatogram (HPLC) to determine the plasma concentration of Ara-C, its metabolite Ara-U and infusion rate in 37 children with acute leukemia, their therapeutic reaction, remission, treatment-related infection, side-effect and long-term treatment effect were analyzed in statistic. Results Ara-C by 1~2 g/m2 intravenous drop infusion for 2 hours, the peak plasma concentration time was 2 h and peak concentration were (14.37-84.44)μmol/L, and the median was (41.42±22.80)μmol/L. The median infusion rate was 869.57at 30 minutes after Ara-C drip completion, its average level was (253.40±81.49) μmol/L, over six-times than Ara-C peak concentration. The median continuous complete remission time in 37 children was 29.8 months (5.0~53.1 months), 3y-DFS was (90.63±5.15)%. The therapy-related infection rate was 56.8 %(21/37),including three children (8.1 %) suffered from severe infection, but there was no therapy-related death and no children were off the protocol due to poor tolerance. Conclusion As post-remission treatment, high-dose Ara-C would not cause cumulation in vivo in children with acute leukemia and side-effect were slight. Ara-C could improve the long-term continuous complete remission rate and clinical cure rate for children with leukemia. Therefore, it was worth to apply in clinical.
