摘要: 目的:分析BRAF V600E、CK19及Galectin-3抗体在甲状腺乳头状癌(papillary thyroid carcinoma, PTC)中的表达情况,并结合PTC的临床病理特征,探讨BRAF V600E抗体的诊断价值。方法:对80例PTC患者的临床病理资料进行分析,并以31例结节性甲状腺肿、13例桥本甲状腺炎患者作为对照组,观察BRAF V600E、CK19、Galectin-3 3种抗体在PTC组与对照组间的表达差异,并分析BRAF V600E抗体与PTC临床病理特征间的相关性。结果:PTC患者甲状腺被膜侵犯情况与淋巴结转移率有关(P<0.05)。80例PTC患者病理组织中的BRAF V600E、CK19及Galectin-3抗体阳性率分别为62.50%、98.75%、95.00%,联合运用CK19及Galectin-3,其诊断灵敏度达95.00%;BRAF V600抗体的诊断特异度为100%,分别与CK19、Galectin-3联合运用,可提高诊断特异度。BRAF V600E抗体表达与PTC患者的年龄、性别、肿瘤直径、甲状腺被膜侵犯与否、淋巴结转移、组织学亚型等临床病理参数间均无统计学相关性(P>0.05)。结论:联合运用BRAF V600E、CK19、Galectin-3抗体有助于PTC的病理诊断,BRAF V600E抗体可起到对BRAF V600E基因突变的初筛作用。

Abstract: Objective: To investigate the expressions of BRAF V600E, CK19 and galectin-3 antibodies in papillary thyroid carcinoma, and study the diagnostic value of BRAF V600E antibody when in corporating with the clinicopathological characteristics of PTC. Methods: The clinicopathological data of 80 patients with PTC were analyzed; 31 cases of nodular goiter and 13 cases with Hashimoto thyroiditis were served as controls. BRAF V600E, CK19 and galectin-3 antibodies in PTC and control group were detecteds and the correlation between BRAF V600E antibody and clinicopathological characteristics of PTC was analyzed. Results: Correlation between thyroid membrane invasion and lymph node metastasis was observed in PTC patients(P<0.05). The positive rates of BRAF V600E, CK19 and galectin-3 antibodies in patients with PTC were 62.50%, 98.75%, 95.00%, respectively. The sensitivity of CK19 combined with galectin-3antibodies was 95.00%, and the specificity of BRAF V600 antibody was 100%. The specificity of CK19 and galection-3 antibodies could be improved by combining with BRAF V600 antibody. There was no statistical correlation between expression of BRAF V600E antibody and age, gender, lesion size, thyroid membrane invasion, lymph node metastasis, histological subtype of PTC (P>0.05). Conclusions: The combined detection of BRAF V600E, CK19 and Galectin-3 antibodies is helpful for the pathological diagnosis of PTC.Meanwhile, BRAF V600E antibody plays a preliminary screening role for the mutation of BRAF V600E gene.
