【摘要】 目的:探讨甲状腺乳头状癌合并桥本氏甲状腺炎患者的BRAF基因表达特点以及侵袭性。方法:将86例甲状腺乳头状癌患者依据是否合并桥本氏甲状腺炎分为对照组和观察组,统计两组病理学特征、BRAF基因表达和侵袭性检测结果,并进行比较。结果:两组性别、年龄、甲状腺弥漫性肿大和血清自身免疫抗体水平相比,差异均有统计学意义(P<0.05)。观察组BRAF基因突变率、甲状腺外侵犯率和淋巴结转移率明显低于对照组(P<0.05);BRAF基因表达呈阳性的患者更容易发生甲状腺外侵犯和淋巴结转移(P<0.05)。结论:桥本氏甲状腺炎可以对甲状腺乳头状癌侵袭性有一定限制作用。

【Abstract】 Objective:To investigate the expression characteristics and invasiveness of BRAF gene in patients with papillary thyroid carcinoma complicated with Hashimotos thyroiditis.Method:A total of 86 patients with papillary thyroid carcinoma were divided into the control group and the observation group according to whether or not combined Hashimotos thyroiditis,43 cases in each group.The histopathological features,BRAF gene expression and invasive test results of two groups were compared.Result:There were statistical significance in the gender,age,thyroid diffuse enlargement and serum autoimmune antibody level of two groups(P<0.05).The BRAF gene mutation rate,thyroid invasion rate and lymph node metastasis rate of the observation group were significantly lower than those of the control group(P<0.05).The patients with BRAF gene expression were more likely to develop thyroid invasion and lymph node metastasis(P<0.05).Conclusion:Hashimotos thyroiditis can have a certain limit on the invasiveness of thyroid papillary carcinoma.

甲狀腺癌在肿瘤患者中所占比例为1.3%~1.5%[1],其是临床上常见的一种病发于甲状腺上皮细胞恶性肿瘤。临床上将甲状腺癌分为乳头状癌、滤泡状腺癌、髓样癌和未分化癌等4种病理类型,其中最常见的病理类型是甲状腺乳头状癌,在甲状腺癌患者中所占比例高达80%[2]。甲状腺乳头状癌患者并发桥本氏甲状腺炎的可能性非常高,相关研究表明发生率为10%~58%[3]。甲状腺乳头状癌患者是否病发桥本氏甲状腺炎会影响治疗方式的选择,临床诊断中发生误诊的概率较大。为了解临床合并甲状腺炎的甲状腺癌患者与单纯甲状腺癌患者的侵袭性,研究以南方医科大学深圳医院和深圳市第二人民医院2015-2017年收治的86例甲状腺乳头状癌患者为研究对象,现报道如下。
1 资料与方法
1.1 一般资料 选取2015年2月-2017年2月在南方医科大学深圳医院和深圳市第二人民医院接受治疗的甲状腺乳头癌患者86例为研究对象,所有患者均经病理学检查确诊,且签署了知情同意书。……
