Abstract:
Objective To investigate the expression and clinical significance of Bcl-2,NF-κB and C-myc in diffuse large B cell lymphoma (DLBCL) tissue.Methods Sixty-seven cases of DLBCL tissue were selected as the observation group,and contemporaneous 21 cases of lymphoid reactive hyperplasia(RH) tissues as the control group.The levels of Bcl-2,NF-κB,C-myc protein expression in tissues were detected by the S-P method.Then their relationship with the clinicopathological features of DLBCL was analyzed.Results Th epositive expression rates of Bcl-2,NF-κB and C-myc protein in DLBCL tissues were 58.21%,62.69% and 77.61% respectively,which in RH tissue were 0.00%,19.05% and 23.81% respectively,the difference was statistically significant(P<0.05);the Bcl-2 protein expression had no significant correlation with the age,gender,disease location,serum LDH level and extranodal sites in DLBCL patients (P>0.05),was significantly correlated with clinical stage and IPI grade (P<0.05);the NF-κB protein expression had no significant correlation with age and gender in the patients with DLBCL (P>0.05),was significantly correlated with clinical stage,location,IPI grade and serum LDH level (P<0.05);the C-myc protein expression had no significant correlation with age,gender,disease location,serum LDH level and extranodal sites (P>0.05),was significantly correlated with clinical stage and IPI grade (P<0.05).Bcl-2 had stronger positive correlation with NF-κB expression in DLBCL tissues (r=0.671,P<0.05),and had no correlation with C-myc in DLBCL tissue (P>0.05),NF-κB and C-myc expression in DLBCL tissues showed weak positive correlation (r=0.293,P<0.05).Conclusion Bcl-2,NF-κB,C-myc expressions are closely correlated with the clinical stage and IPI grade of DLBCL and can serve as the reference indicators for evaluating DLBCL prognosis.
