ABSTRACT
Objective:
To investigate the expression of CD56 antigen in leukemia cells of the patients with acute myeloid leukemia (AML)and its relationship with the prognosis of AML, and to clarify the role of CD5 6 antigen expression in predicting the prognosis of the AML patients.Methods:
171 AML (non-M3)patients aged from 14 to 60 years old,who received a IA Regimen as the first time inducing chemotherapy were chosen.Flow cytometric analysis was used to evaluate the CD56 expression in leukemia cells.COX proportional regression analysis was used to select the prognostic factors,and bivariable analysis was used to study the relationship between the positive rate of CD56 and overall survival (OS).The CD56+ group (n=52),including CD56≥50% expression group (n=39) and CD560.05),while the 2-year survival rate in CD56≥50% group was lower than that in CD560.05).The relapse rate and first year relapse rate of patients in CD56+ group (64.3% and 37.5%)were significantly higher than those in CD56- group (34.3% and 17.9% )(P0.05).The DFS in CD56+ group was shorter than that in CD56- group (P<0.05).The same DFS result was also found between CD56≥50%group and CD56<50% group (P<0.05).Conclusion:
The expression of CD56 antigen in leukemia cells predicts a bad prognosis in the AML patients,and the higher expression of CD56 indicates the worse prognosis.
