目的:探讨宫颈癌p53、c-erbB-2蛋白的表达及临床意义。方法:采用免疫组织化学E liV ision二步法检测43例宫颈癌组织切片的p53、c-erbB-2蛋白表达,并结合临床病理资料进行分析。结果:(1)p53、c-erbB-2蛋白阳性表达率分别为74.4%和69.8%;(...目的:探讨宫颈癌p53、c-erbB-2蛋白的表达及临床意义。方法:采用免疫组织化学E liV ision二步法检测43例宫颈癌组织切片的p53、c-erbB-2蛋白表达,并结合临床病理资料进行分析。结果:(1)p53、c-erbB-2蛋白阳性表达率分别为74.4%和69.8%;(2)p53蛋白的表达在鳞癌高于腺癌(P<0.05),其表达与年龄、临床分期、临床分型、病理分级、宫旁浸润、近期疗效无明显相关(P>0.05);(3)c-erbB-2蛋白的表达在鳞癌的病理分级、宫旁浸润中有显著差异(P<0.01),在临床分期的表达中也有显著差异(P<0.05),但与年龄、临床分型、近期疗效、病理类型、腺癌的病理分级无明显相关(P>0.05);(4)p53与c-erbB-2蛋白共同阳性表达在癌旁浸润中,有显著差异(P<0.01),二者阳性表达随宫颈癌临床分期表达增高(P<0.05)。结论:c-erbB-2蛋白阳性表达与宫颈癌恶性程度呈正相关;p53与c-erbB-2蛋白共同阳性表达与癌旁浸润有关,随临床分期表达增高,提示宫颈癌的发生发展可能有多种癌基因共同参与。展开更多
