title: [Clinical characteristics and prognoses of 167 acute erythroleukemia patients].
abstract: OBJECTIVE
  To observe the biological characteristic and the prognoses in patients with acute erythroleukemia (AEL).
  
  
  METHODS
  The results of 167 patients with newly diagnosed AEL, from January 2003 and June 2013 in the First Affiliated Hospital of Soochow University, were reviewed by MICM.
  
  
  RESULTS
  Flow cytometry analysis indicated that CD13(96.1%), CD33(95.1%), CD117(87.4%) and CD34 (79.4%) were highly expressed in AEL. 56 of 148 (37.8%) AEL patients had a variety of cytogenetic abnormalities, 27 of 148(18.2%) patients were complex karyotype (abnormalities involving 3 or more chromosomes), the abnormalities of chromosomes 3, 5, 7 and 8 were more frequently involved and the most common one was ＋8, accounting for 35.7% of all abnormal karyotype, followed by 5q- (17.9%). Mutation analysis showed CEBPA mutation ratio of AEL patients was 44.0% (11/25), that of NPM1 as 15.4% (4/26). Initial induced remission rate of AEL was 56.6% (30/53), compared by 33.3% (4/12) of MDSM6. Survival analysis showed that the overall survival in female was better than that in male (P=0.047). The overall survival time of transplantation group is significantly longer than chemotherapy group (P=0.000). The OS of 13-39 years old group was the best, 40-49 years old group took second place, >50 years old group appeared to be the worst.
  
  
  CONCLUSIONS
  AEL had its own unique biological features, and allogeneic hematopoietic stem cell transplantation could significantly improve its poor prognosis.
