摘要
目的检测HER2在膀胱尿路上皮细胞癌、癌旁黏膜、正常膀胱黏膜组织中的表达,探讨HER2表达与膀胱尿路上皮细胞癌临床特征、病理分级、临床分期间的关系,评价它是否可以作为判断膀胱尿路上皮细胞癌生物学行为的指标。方法收集临床病理资料完整的膀胱尿路上皮癌及相应癌旁组织各50例,正常膀胱组织20例,应用免疫组化法(SP法)检测HER2蛋白的表达。结果HER2蛋白在膀胱尿路上皮细胞癌组织中的表达高于癌旁黏膜和正常膀胱黏膜中的表达,差异有统计学意义(P<0.05);HER2蛋白的表达和病理分级、肿瘤大小有相关性,差异有统计学意义(P<0.05)。结论HER2蛋白表达和肿瘤的病理分级、肿瘤大小等有相关性,表明HER2蛋白过表达可能与膀胱癌的发生和发展密切相关。
Objective To study the expression of HER2 in uroepithelium cell carcinoma of bladder,mucosa in the paracarcinoma and normal mucous of urinary bladder, and to explore its correlation with clinic factors,grade and stage of the bladder carcinoma and evaluate whether HER2 can serve as marker to decide the biological behavior of bladder carcinoma. Methods 50 specimens of uroepithelium cell carcinoma of bladder,50 specimens mucosa in the paracarcinoma and 20 cases normal mucous of urinary bladder were collected. The protein expression of HER2 was detected by immunohistochemical staining SP method. Results The expression of HER2 protein in uroepithelium cell carcinoma of bladder tissues was significant higher than that in paracarcinoma mucosa and normal mucous of urinary bladder （ P 〈0.05）. The expression of HER2 protein in uroepithelium cell carcinoma of bladder tissues had dependablity correlation with the grade and size of the tumors （ P 〈0.05）. Conclusion The expression of HER2 protein in uroepithelium cell carcinoma of bladder tissues had significant correlation with the grade and size of the tumors. It illustrates that the over expression of HER2 protein maybe had highly correlation with the oncogenesis and development of bladder cancer.
