Résumé

<p><b>OBJECTIVE</b>To observe the biological characteristic and the prognoses in patients with acute erythroleukemia (AEL).</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>AEL had its own unique biological features, and allogeneic hematopoietic stem cell transplantation could significantly improve its poor prognosis.</p>
