Objective:
To explore the impact on efficacy and prognosis of low-risk and intermediate-risk acute myeloid leukemia (AML, non-M3) patients with complete remission (CR) treated by high-dose cytarabine (HD-Ara-C) or standard-dose cytarabine(SD-Ara-C) before haploidentical hematopoietic stem cell transplantation (Haplo-HSCT).
Methods:
A retrospective analysis was performed on 71 low-risk and intermediate-risk adult AML patients in the First Affiliated Hospital of Soochow University from March 2008 to April 2017. All the patients were treated by consolidation regimens containing cytarabine before Haplo-HSCT. According to the dosages of cytarabine, the patients were divided into HD-Ara-C group and SD-Ara-C group. Kaplan-Meier method, log-rank test and Cox regression model were used to make survival analysis, and the prognosis and efficacy between the two groups were compared.
Results:
Of the 71 patients, 43 were male and 28 were female, and the median age was 37 years (18-56 years). The median follow-up time was 39 months (6-119 months). Sixty-four patients were in first remission, and 7 patients were in second remission. At the end of follow-up, the 2-year cumulative incidence of recurrence (CIR), overall survival (OS) rate, progression-free survival (PFS) rate, and non-recurrent death (NRM) rate in SD-Ara-C group were 19.33%, 77.44%, 80.67%, and 17.29%, respectively, the 2-year CIR, OS rate, PFS rates and NRM rate in HD-Ara-C group were 6.29%, 79.90%, 93.71%, and 17.68%, respectively. There was no significant difference in CIR (
