鼻咽癌组织中CerbB-2的表达及其意义

目的:探讨表皮生长因子受体-2(CerbB-2)在鼻咽癌组织中的表达情况及其意义.方法:采用免疫组织化学SP法检测CerbB-2在90例鼻咽癌组织和22例鼻咽炎性组织中的表达情况,分析CerbB-2表达水平与鼻咽癌临床病理因素的关系.结果:90例鼻咽癌组织中CerbB-2表达的阳性率为65.56%,22例鼻咽炎性组织中CerbB-2表达的阳性率为31.82%(P<0.05);鼻咽癌组CerbB-2表达在淋巴结分期N_2和N_3患者中阳性率为81.0%,N_0和N_1患者阳性率为52.1%(P<0.05).而与患者年龄、性别、临床分期、T分期和远处转移无明显相关(P>0.05).结论:CerbB-2在鼻咽癌组织中高表达,它可能是鼻咽癌发生和发展过程中的一个重要因素.

CerbB-2 Expression and Significance in Patients with Nasopharyngeal Carcinoma

Objective: To investigate the biological significance of CerbB-2 expression in nasopharyn-geal carcinoma. Methods: The expression of CerbB-2 was detected in 90 nasopharyngeal carcinoma tissues and 22 nasopharyngitis tissues by SP immunohistochemical method. The relationship between CerbB-2 ex-pression and clinicopathological characteristics of nasopharyngeal carcinoma was investigated. Results: The positive expression rate of CerbB-2 protein was 65.56% in nasopharyngeal carcinoma tissues, and 31.82% in nasopharyngitis tissues, with a significant difference (P<0.05). The ratio of expression was 81.0% in patients of N_2 and N_3 lymth node stage, significantly different from that in patients of N_0 and N_1 lymph node stage (52.1%, P<0.05). The expression of CerbB-2 gene was not correlated with age, gender, clinical stage, T stage and distant metastasis of nasopharyngeal carcinoma (P>0.05). Conclusion: There is a high expression of CerbB-2 in nasopharyngeal carcinoma tissues, which might be an important event in the pathogenesis and progression of nasopharyngeal carcinoma.
