CerbB-2 Expression and Significance in Patients with Nasopharyngeal Carcinoma / 中国肿瘤临床

ABSTRACT

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.
