【摘要】 目的:研究HIF-2α、HSP90和VEGF在人肾透明细胞癌中的表达,分析肾透明癌中HIF-2α、HSP90和VEGF表达的相关性及其与肾癌临床病理、预后之间的关系。方法:应用免疫组织化学S-P法检测60例肾透明细胞癌、20例癌旁组织及5例正常肾组织中HIF-2α、HSP90和VEGF的表达,比较HSP90、HIF-2α及VEGF表达关系及其与肾癌的病理分级、临床分期等临床病理之间的关系,根据随访资料探讨上述三者与肾细胞癌患者预后的关系。结果:HIF-2α、HSP90及VEGF在肾癌标本中的表达明显高于对照组,差异有统计学意义(P<0.05),与肾癌的分期、肿瘤大小、淋巴转移及局部浸润有关;三个指标之间,两两呈显著正相关。三者与肾细胞癌患者生存期之间关系分析提示HSP90阴性组生存率有高于阳性组的趋势,HIF-2α、VEGF阳性组病例的预后显著差于阴性组,差异有统计学意义。结论:HIF-2α、HSP90和VEGF在肾癌中高表达并与肾癌的临床分期、肿瘤大小密切相关,且三指标间的表达两两呈显著正相关。HIF-2α和VEGF是影响肾细胞癌预后的独立因素。联合检测HIF-2α、HSP90和VEGF可作为判断肾癌病理生物学行为的指标,有助于提高对肾癌侵袭转移能力的评估。更多还原

【Abstract】 Objective: To investigate the expression of the HSP90、HIF-2αand vascular endothelial growth factor (VEGF) in renal clear cell carcinoma(RCC). Analyze the relationship among these protein and the clinicopathologic features of human renal cell carcinoma. To explore the role of HSP90、HIF-2αand VEGF in the outcome of renal cell carcinoma.Methods: Formalin-fixed paraffin embedded tissues from 60 cases of RCC and 20 cases of normal renal tissues which were closely adjacent to carcinoma and 5 cases of normal renal tissues were evaluated for HSP90、HIF-2αand VEGF protein expression by immunnhistochemical S-P method. Analyze the significance of them with the clinicopathologic features and outcome in human renal cell carcinoma.Results: The positive incidence of expressions HSP90、HIF-2αand VEGF protein in RCC were prominently higher than control group, and significant correlations were observed among them. The expressions of HSP90、HIF-2αand VEGF were closely related with the stage, LN metastasis and the size of tumor of renal cell carcinoma. The survival rate is slightly higher in renal cell carcinoma, which has low expression of HSP90. The overall survival rate is higher in renal cell carcinoma, which has low expression of HIF-2αand VEGF.Conclusion: Increased expression of HIF-2α、HSP90 and VEGF are markedly correlated with clinical stage and the size of tumor, and HIF-2αpositively correlated with the expression of HSP90 and VEGF .Combined detection of HSP90、HIF-2αand VEGF maybe helpful to evaluate prognosis and infiltrative capability of RCC.更多还原
