摘要 目的探讨BRAF V600E突变蛋白质表达与甲状腺乳头状癌(PTC)临床病理特性的关系。方法应用抗BRAF V600E单克隆抗体和免疫组化SABC法检测PTC(n=50)、结节性甲状腺肿(n=30)、甲状腺腺瘤(n=25)石蜡包埋组织切片中BRAF V600E突变蛋白质的表达,半定量分析BRAF V600E突变蛋白质表达与PTC临床病理生物学特性的关系。结果 PTC BRAF V600E突变蛋白质的阳性表达率为74%(37/50),甲状腺良性病变组织中的表达率为0,差异有统计学意义(P<0.05)。PTC BRAF V600E突变蛋白质的表达水平与颈部淋巴结转移、肿瘤分期(Ⅰ~Ⅱ期vsⅢ~Ⅳ期)和组织分型(经典型vs滤泡亚型)有关,差异均有统计学意义(P<0.05)。性别、年龄、肿瘤大小、甲状腺被膜外组织受侵犯与否对其表达水平均差异无统计学意义(P>0.05)。结论应用免疫组织化学技术可检测PTC石蜡组织切片BRAF V600E突变蛋白质的表达,可为PTC鉴别诊断,手术治疗和预后判断提供参考资料。
