摘要: 目的探讨Twist、E-cadherin在甲状腺乳头状癌中的表达和相互关系及其临床病理意义。方法 应用免疫组化方法, 对60例甲状腺乳头状癌、40例结节性甲状腺肿及40例良性乳头状病变进行Twist、E-cadherin表达的研究。结果 甲状腺乳头状癌Twist及E-cadherin阳性表达率分别为81.67%(49/60)及21.67%(13/60), 结节性甲状腺肿Twist及E-cadherin阳性表达分别为0%(0/40)及87.50%(35/40), 良性乳头状病变Twist及E-cadherin阳性表达分别为7.5%(3/40)及100%(40/40), 前者与后两者相比差异有统计学意义(P<0.05);Twist及E-cadherin在甲状腺乳头状癌中的表达水平与病人的年龄及原发肿瘤分期无关, 但与有无淋巴结转移相关(P<0.05);Twist与E-cadherin的表达呈负相关(r=-0.796, P=0.000)。结论 在大多数甲状腺乳头状癌的上皮细胞中都存在Twist过表达及E-cadherin表达下调, 其淋巴结转移的发生与Twist过表达及E-cadherin的表达减少或功能的不正常可能有密切的关系;Twist与E-cadherin的表达呈负相关。

Abstract: Objective To study the expression of Twist, E-cadherin in Papillary thyroid carcinoma(PTC)and the relationship with clinicpathological factors.Methods Twist and E-cadherin were measured in papillary thyroid carcinomas(n=60), nodular goiter(n=40), benign papillary lesions(n=40)by immunohistochemical staining.Resusts In papillary thyroid carcinoma(PTC), positive rates of Twist and E-cadherin were 81.67%(49/60)and 21.67%(13/60);in nodular goiter(NG), positive rates were 0%(0/40)and 87.50%(35/40);in benign papillary lesions(BPL), positive rates were 7.5%(3/40)and 100%(40/40), respectively.There were statistic significance compared PTC with NG and BPL.The positive expression of Twist and E-cadherin were both related to lymph node metastasis.The expression of Twist showed negative correlation with E-cadherin.Conclusions Twist expression in PTC was increased and E-cadherin was reduced.They were both correlated with lymph node metastasis.The expression of Twist showed negative correlation with E-cadherin.
