摘要
目的:探讨甲状腺癌组织中CD44v6和Bcl-2蛋白的表达与肿瘤发生和转移的关系,并探讨CL44v6和Bcl-2表达的相关性。方法:应用催化信号放大系统免疫组化技术,检测50例甲状腺癌、45例甲状腺腺瘤和20例癌旁正常甲状腺组织中CD44v6和Bcl-2蛋白表达。结果:在甲状腺癌CD44v6和Bcl-2表达阳性率分别为64.0％和46.0％,均显著高于甲状腺腺瘤和癌旁正常甲状腺组织（P<0.05）,CD44v6和Bcl-2阳性率均与甲状腺癌淋巴结转移相关（P<0.05）。CD44v6和Bcl-2表达呈正相关。结论:CD44v6和Bcl-2表达对预测甲状腺癌转移和评估预后是一种重要参考指标。
Objective:In order to study the correlation between The expression of CD44v6 protein and Bcl-2 protein in thyroid cancer were examined.Methods:The expression of CD44v6 and Bcl-2 in 50 thyroid cancers,20 adjacent noncancerous portion,45 adenoma and 10 normal thyroid tissue were respecitively investigated by catalyzed signal amplification immunohistochemical technique. Results:The positive rate of CD44v6 and Bcl-2 in thyroid cancer was 64.0% and 46.0%, which was significantly higher than that in adenoma or adjacent noncancerous ( P < 0.05). The percentage of CD44v6 and Bcl-2 positive exoression were found to be significantly correlated with the tumor metustasis (P<0.05),but not correlated with histological feature. Expression of CD44v6 was significantly correlated with Bcl-2.Conclusion:Expression of CD44v6 and Bcl-2 can be regarded as parameter to evaluate tumor metastasisi and prognosis of thyroid cancer.
