摘要 目的分析PTEN蛋白和肿瘤坏死因子(TNF-α)在甲状腺乳头状癌中的表达及意义。方法应用免疫组化方法检测60例甲状腺乳头状癌和60例甲状腺腺瘤手术切除标本中的PTEN蛋白和TNF-α的表达及关系,研究甲状腺乳头状癌临床病理因素与PTEN蛋白和TNF-α的关系。结果 PTEN蛋白在甲状腺乳头状癌中阳性表达率显著低于甲状腺腺瘤的阳性表达率,差异有统计学意义(P<0.05)。而TNF-α在甲状腺乳头状癌中阳性表达率显著高于甲状腺腺瘤,差异有统计学意义(P<0.05)。有无淋巴结转移、有无浆膜浸润、不同临床TNM分期的患者,癌组织中PTEN蛋白和TNF-α的阳性表达率比较,差异均有统计学意义(P<0.05);而不同性别、年龄、肿瘤大小的患者,癌组织中二者的阳性表达率间差异无统计学意义(P>0.05)。PTEN蛋白与TNF-α的表达呈负相关(r=-0.338,P<0.05)。结论 PTEN蛋白和TNF-α的表达改变与甲状腺乳头状癌的形成有一定关系。二者表达状况的检测对甲状腺乳头状癌的诊断、治疗及预后具有重要的临床意义。
