Analysis on prognostic factors of acute myeloid leukemia / 白血病·淋巴瘤

ABSTRACT

Objective To investigate the correlated factors of prognosis for acute myeloid leukemia (AML).Methods A retrospective analysis of initial 182 patients with AML was performed to assess the relationship between prognostic factors including sex,age,white cell count at diagnosis,immunophenotype,cytogenetics,allo-HSCT and complete remission (CR) after one-course of induction and overall survival (OS) or event free survival (EFS).Results The median age of 182 patients was 49 (14-80) years old,and the median follow up was 9.7 (0.5-75.5) months.There were 107 patients achieved CR after one-course of induction (total response rate was 65.9 ％,120/182),age≥60 years.CD64 negative,unfavorable cyto-genetics and failing to achieve CR after one-course of induction were associated with lower total CR rate.Univariate analysis results demonstrated that age ≥60 years,unfavorable cytogenetics,CD11b expression and failing to achieve CR after one-course of induction had poor influence on 3-years OS and EFS,while the 3-years OS and EFS for patients with CD19 expression,CD64 expression and allo-HSCT were better than that of the patients with negative CD19 and CD64.Multivariate analysis suggested that age,cytogenetics,CD11b,CD64,allo-HSCT and CR after one-course of induction were independent prognostic factors for OS,while cytogenetics,CD64,allo-HSCT and CR after one-course of induction were important on EFS.Conclusions Prognostic analysis depending on AML corelation factors is benifit to individual therapy and can be applied to improve the survival.
