摘要
目的探讨鞘氨醇激酶1(sphingosine kinase1,SphK1)和膜联蛋白A1(Annexin A1)在甲状腺乳头状癌(papillary thyroid carcinoma,PTC)中的表达及相互关系。方法收集PTC 81例、结节性甲状腺肿(nodular goiter,NG) 30例、癌旁正常甲状腺组织(normal thyroid,NT) 26例。应用免疫组化En Vision两步法检测各组中SphK1和Annexin A1的表达,并分析两者表达与PTC临床病理特征的关系。结果 SphK1和Annexin A1在PTC中的阳性率(60. 5%和61. 7%)高于NG组(33. 3%和26. 7%)以及NT组(30. 8%和23. 1%)(P均<0. 017)。Annexin A1和SphK1表达与PTC淋巴结转移和临床分期相关(P均<0. 01),与患者性别、年龄、部位、肿瘤大小、TG-Ab值和TPO-Ab值无关(P均> 0. 05)。SphK1与Annexin A1表达呈正相关(P <0. 01)。结论 SphK1与Annexin A1可能参与PTC的发生、发展和淋巴结转移,提示二者可能成为甲状腺肿瘤良恶性诊断和早期淋巴结转移风险评估的重要生物学因子。
