鼻咽癌组织中血管内皮生长因子和生存素的表达

目的 探讨血管内皮生长因子（VEGF）和生存素（Survivin）在鼻咽癌组织中的表达情况和意义.方法 应用免疫组化法检测VEGF和Survivin在80例鼻咽癌组织和24例鼻咽慢性炎性组织中的表达水平.结果 VEGF在鼻咽炎性组织中表达率为25.00%（6/80）,在鼻咽癌组织中的表达率为75.76%（61/80）,两者差异有统计学意义（P〈0.01）,Survivin在鼻咽炎性组织中表达率为16.67%（4/80）,在鼻咽癌组织中的表达率为67.50%（54/80）,两者差异有统计学意义（P〈0.01）.VEGF蛋白表达水平与TNM分期、T分期、淋巴结转移、远处转移有关（P〈0.05）,Survivin蛋白表达水平与TNM分期、淋巴结转移、远处转移有关（P〈0.05）.结论同时检测VEGF和Survivin有利于评估鼻咽癌的生物学行为和判断鼻咽癌预后.

Expression of VEGF and Survivin in Nasopharyngeal Carcinoma

Objective To explore the expression of vascular endothelial growth factor(VEGF) and Survivin in nasopharyngeal carcinoma.Methods Immunohistochemical method staining for the paraffin sections(SP method) were used to assess the expression of VECF and Survivin expression in 80 cases of nasopharyngeal carcinoma tissues and 24 cases of nasopharyngeal chronic inflammation tissues.Results The overexpression rate of VEGF protein was 75.76% (61/80) in nasopharyngeal carcinoma tissues,and 25.00% (6/80) in nasopharyngeal chronic inflammation tissues(P<0.01) ;The overexpression rate of Survivin protein was 67.50% (54/80) in nasopharyngeal carcinoma tissues,and 16.67% (4/80) in nasopharyngeal chronic inflammation tissues(P<0.01).The expression of VEGF was related to TNM stage,T stage,lymph node metastasis and distant metastasis (P<0.05) ,and there was a close relation between the expression of Survivin and TNM stage,T stage,lymph node metastasis and distant metastasis (P<0.05).Conclusion Detecting the expression levels of VEGF and Survivin proteins simultaneously in nasopharyngeal carcinoma had certain reference value for judging biological behavior and evaluating prognosis of patients with nasopharyngeal carcinoma.
