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.

Background and purpose:The association between metabolic syndrome (MS) and renal cell carcinoma (RCC) is still unknown. The aim of this study was to elucidate how MS correlates with the prevalence and malignancy of RCC.Methods:This study enrolled 398 RCC patients (350 clear cell RCC patients, 5 XP11.2 transloca-tion RCC patients, 16 papillary RCC patients and 27 chromophobe RCC patients), 160 normal persons, and 32 benign renal tumor patients. The metabolic status of the patients was assessed, and the link between MS and the prevalence or malignancy of RCC was calculated.Results:Clear cell RCC patients had signiifcantly higher rates of hypertension, higher body mass index (BMI) and longer waist circumference. Forty-eight percent clear cell RCC patients had MS, while the number was 33% for papillary RCC, 26% for chromophobe RCC, 0% for XP11.2, 17% for AML, and 25%for normal people. MS patients had signiifcant higher rates of having clear cell RCC than no-MS patients, however this kind of difference was not seen in other types of RCC. Clear cell RCC patients with higher Furhman grade had lower rates of MS.Conclusion:Patients with MS are more likely to develop clear cell RCC. Patients with high Furhman grade tumors have low MS rates, indicating that high grade tumor may have other originating mechanisms other than metabolic disorders.
