Expression and correlation of survivin, COX-2 and bcl-2 in non-Hodgkin lymphoma / 白血病·淋巴瘤

ABSTRACT

ObjectiveTo investigate the expression of survivin,COX-2 and bcl-2 in non-Hodgkin lymphoma(NHL)and the significance and correlation between them.MethodsImmunohistochemistry MaxVision systems for survivin,COX-2 and bcl-2 were conducted on 44 NHL and 20 reactive lymphoid hyperplasia (RH).ResultsThe positive expression rates of survivin,COX-2,bcl-2 in NHL were 70.45 ％(31/44),68.18 ％ (30/44),63.64 ％ (28/44),respectively,and these in RH were 40.00 ％ (8/20),40.00 ％(8/20) and 20.00 ％ (4/20),respectively.There was positive correlation between the expression of COX-2 and survivin (r =0.306,P =0.043),survivin and bcl-2 protein (r =0.339,P =0.040) in NHL.ConclusionCOX-2,survivin,bcl-2 are highly expressed in NHL.To detect the expression of them has clinical value to diagnosis NHL and to estimate the malignant degree of lymphoma.There are a positive correlations between the expression of COX-2 and survivin protein,and between the expression of survivin and bcl-2 protein,which indicates that they may play a synergistic role in the occurrence and development of NHL.
