Abstract: Objective To explore the relationship between the expression of NF-κB and VEGF and the biological behaviors of prostatic carcinoma.Methods Immunohistochemical method was used to examine the expression of NF-κB and VEGF in 40 cases of benign prostatic hyperplasia (BPH) and 53 cases of prostatic carcinoma.Results The positive rates of NF-κB and VEGF in prostatic carcinoma and BPH were 64.2％ and 69.8％,12.5％ and 37.5％ respectively.There are more cases with positive NF-κB and VEGF expression in prostatic carcinoma group than in the BPH group( x2 =24.976,9.655,P ＜ 0.01 ).The expression of VEGF and NF-κB in prostatic carcinomas increased significantly with the decrease of tumor differentiation and advance of the TNM stages(x2 =15.936,18.459;4.316,14.205,P ＜0.01 or P ＜0.05);The expression of VEGF in prostatic carcinoma was positively correlated with NF-κB ( r =0.297,P =0.027 ).Conclusion The expression of VEGF and NF-κB in prostatic carcinoma are highly correlated with each other and may be suggestive to understand the biological behavior of prostatic carcinoma.
