摘要 目的观察甲状腺乳头状癌(PTC)组织中BRAF基因突变及细胞周期调控基因蛋白(Cyclin D1)表达情况,探讨其临床意义。方法采用聚合酶链反应-单链构象多态性技术检测115例PTC组织中BRAF基因,通过DNA序列分析计算基因突变率;采用免疫组织化学技术检测Cyclin D1蛋白。结果本组BRAF基因突变率为48.7%(56/115),Cyclin D1蛋白阳性表达率为65.2%(75/115);颈淋巴结转移阳性与阴性者BRAF基因突变率分别为73.5%(25/34)、38.3%(31/81),P=0.001;Cyclin D1蛋白阳性表达率分别为70.6%(24/34)、63.0%(51/81),P=0.522;BRAF基因突变者Cyclin D1蛋白阳性表达率为80.4%(45/56),BRAF基因野生型者Cyclin D1蛋白阳性表达率为50%(30/59),二者比较P=0.002。结论 BRAF基因突变及Cyclin D1蛋白阳性表达对PTC的发生、发展起促进作用,二者对评估PTC患者的预后及术后复发的综合治疗效果有一定临床价值。
