摘要

目的:通过研究甲状腺癌的的分子水平特征,研究其发病机制并找到有效的治疗方法。通过免疫组织化法对甲状腺癌的癌组织及正常甲状腺组织中NIS蛋白的检测,明确NIS的表达与甲状腺癌的相关性,为甲状腺癌的诊断、治疗、预后提供临床指导意义。方法:选取在我院2019年10月至2020年8月收治的符合甲状腺癌诊断标准并具有完整临床病理资料的患者50例(男性27例,女性23例;年龄9~80岁,中位年龄65岁)),将以上病例的正常甲状腺组织作为对照。对所有病例的临床病理资料进行回顾性分析,通过免疫组织化学方法处理,检测NIS蛋白在甲状腺癌组织及正常甲状腺组织中的表达情况,并比较其差异。结果:免疫组化结果显示:1.在50例甲状腺癌患者中,均未出现NIS阴性表达;甲状腺癌组织NIS蛋白弱阳性表达有49例(98%),在甲状腺癌旁组织中,NIS蛋白弱阳性表达有9例(18%),弱阳性表达率甲状腺癌显著高于甲状腺癌旁组织,差异具有统计学意义(P<0.05);2.在50例甲状腺癌患者中,甲状腺癌组织NIS蛋白阳性表达有1例(2%),在甲状腺癌旁组织中,NIS蛋白阳性表达有14例(28%),阳性表达率甲状腺癌显著低于甲状腺癌旁组织,差异具有统计学意义(P<0.05);3.在50例甲状腺癌患者中,NIS蛋白强阳性表达有0例(0%),在甲状腺癌旁组织中,NIS蛋白强阳性表达有27例(54%),强阳性表达率甲状腺癌显著低于甲状腺癌旁组织,差异具有统计学意义(P<0.05)。4.甲状腺癌NIS蛋白强阳性表达显著低于甲状腺癌旁组织。甲状腺癌NIS免疫组织化学染色产物主要定位在细胞质,且呈弥漫性、棕褐色深染;正常甲状腺NIS阳性产物定位于细胞膜和细胞质,呈淡黄色、分散性着色。结论:甲状腺癌中NIS蛋白表达弱阳性率显著高于甲状腺癌旁组织,而强阳性率明显低于甲状腺癌旁组织;甲状腺癌中NIS蛋白表达强阳性率较甲状腺癌旁组织显著降低;NIS功能蛋白定位于细胞膜, 在不同甲状腺疾病组织中的表达水平有所差异。
