Expressions of CD44v6 in acute leukemia and its implication to clinical outcome / 中国综合临床

ABSTRACT

Objective To investigate the significance of CD44v6 expression in acute leukemia( AL) and it's relation with the prognosis of AL. Methods Sixty AL patients were treated by enzyme linked immunosorbent assay( ELISA)as initial treatment group. Fourty-seven cases were remission as remission group, and 20 cases with no-remission group. Meanwhile,45 healthy people were served as the control group. The level of CD44v6 was measured by ELISA. Results The serum CD44v6 in initial treatment patients,remission group, no-remission group and control group were( 179. 34 ± 39. 41 )μg/L,( 190. 61 ± 28. 05 )μg/L,( 106. 72 ± 26. 38)μg/L and(98. 31 ± 21. 78)μg/L respectively,and the difference was significant( F =56. 303,P﹤0. 01),and the CD44v6 of initial treatment group and remission group were higher than that of no-remission group and control group(P﹤0. 05). The leukocyte levels was positive related to CD44v6 levels in 60 patients(r=0. 826,P﹤0. 01),and it was also related to disease stage,extramedullary infiltration(( r=0. 485,0. 512;P﹤0. 01). Conclusion The level of CD44v6 is closely related with the occurrence and development of acute leukemia. The assay of CD44v6 in serum of AL patients is helpful in diagnosing and predicting the risk of metastasis and prognosis in AL.
