NF-κB、COX-2在肾癌中的表达及其临床意义

目的 研究NF-κB、环氧合酶-2(COX-2)在肾癌中的表达,探讨其与肾癌的发生、发展、转移以及患者预后之间的关系.方法 应用免疫组织化学EnVison二步法对48例肾癌组织及5例正常肾组织中NF-κ B、COX-2的表达情况进行检测,并通过对患者随访,探讨二者与肾癌临床病理学参数及患者预后之间的关系.结果 NF-κ B、COX-2在肾癌组织中的表达均较正常组织明显增高(P<0.05).NF-κ B的表达与肾癌的临床分期之间呈显著的正相关关系(P<0.05),而COX-2的表达与肾癌的临床分期之间无显著相关性(P>0.05).NF-κ B的表达与肾癌病理分级之间无显著相关性(P>0.05).而COX-2的表达与肾癌的病理分级之间呈显著的负相关关系(P<0.05).NF-κ B表达阳性者的生存率明显低于NF-κB表达阴性者(P<0.05),而COX-2表达阴性者的生存率低于COX-2表达阳性者,但差异无统计学意义(P>0.05).NF-κ B与COX-2在肾癌组织中表达差异无统计学意义(P>0.05).结论 NF-κ B、COX-2的表达可能与肾癌的发生、发展有关,NF-κ B的表达可能还与肾癌的转移及患者的预后有关,二者有望作为肾癌早期诊断和判断肾癌患者预后的辅助指标.

The expression of NF-κB and COX-2 protein in renal cell carcinoma and its clinical value

Objective To study the expression of NF-κB and COX-2 protein in renal cell carcinoma, and to investigate the clinical value of it in the occurrence, progression and metastasis of renal cell carcinoma as well as the prognosis of patients. Methods 48 cases of renal cell carcinoma tissues and 5 cases of normal renal tissues were detected by using immunohistochemical method, and following up the patients who were included in the study. Then we analyzed the relationship between NF-κB and COX-2 protein level and clinic pathological parameters as well as the prognosis of patients. Resalts The expression of NF-κB and COX-2 protein were increasing in renal cell carcinoma, the protein levels were significantly different compared with that in normal renal tissues(P <0.05). There were significantly positive correlation between the expression of NF-κB protein and the clinic stages of renal cell earcinoma(P <0.05), but no correlation between the expression of COX-2 protein and them(P >0.05). There were significantly negative correlation between the expression of COX-2 protein and the pathological grades of renal cell careinoma(P <0.05), but no correlation between the expression of NF-κB protein and them (P>O.05). The survival rate of these patients whose expression of NF-κB protein were positive was significantly lower than those of negative expression of NF-κB protein(P <0.05), and there was opposite result for COX-2, but not significanfly(P >0.05). The expression of NF-κB and COX-2 protein in renal cell carcinoma had no significant correlation (P >0.05). Conclusion There may be relationship between the expression of NF-κB and COX-2 protein and the occurrence, progression of renal cell carcinoma, the expression of NF-κB may also have association with metastasis of renal cell carcinoma as well as the prognosis of patients. Detecting the expression of NF-κB and COX-2 protein may be useful in early diagnosis of renal cell carcinoma as well as prognosis evaluation of patients.
