Analysis of clinicopathological characteristics of papillary thyroid carcinoma and BRAF V600E gene mutation

摘要: 目的: 研究BRAF V600E突变与甲状腺乳头状癌(PTC)临床病理特征的相关性,探讨PTC组织BRAF V600E突变检测的应用价值。方法: 采用qPCR方法对108例PTC患者及30例对照组织进行BRAF V600E突变检测,回顾PTC突变型组和野生型组患者的临床病理资料,使用SPSS 21.0软件进行统计学分析。结果: 对照组未检测到BRAF V600E突变。108例PTC患者BRAF V600E突变率为72.20%。突变型组患者平均年龄大于野生型组,差异有统计学意义(P<0.05)。BRAF V600E突变与PTC组织亚型有关,与中央区淋巴结转移有关,差异有统计学意义(P<0.05)。与肿瘤直径、性别、多灶性、癌灶部位、伴随疾病、颈侧区淋巴结转移、被膜侵犯及TNM分期无关(P>0.05)。结论: BRAF V600E突变对PTC预后判断的价值尚待研究,相比于预后判断,对PTC的病理诊断价值更加显著。

Abstract: Objective: To study the correlation between the BRAF V600E mutation and the clinicopathological features of papillary thyroid carcinoma(PTC), and to explore the application value of BRAF V600E mutation in PTC. Method: The BRAF V600E gene mutation was detected in 108 PTC cases and 30 control cases by qPCR. The results were statistically analyzed by using SPSS 21.0 software. Result: The BRAF V600E mutation was absent in the control group. The BRAF V600E mutation rate was 72.20% in 108 PTC cases. Compared with patients with wild-type, the mean age of patients with the mutant BRAF V600E was significantly older(P<0.05). BRAF V600E mutations were associated with PTC tissue subtypes and central area lymph node metastasis(P<0.05). BRAF V600E mutations were not correlated with tumor diameter, patient gender, multifocality, tumor site, concomitant disease, lymph node metastasis in side region of neck, capsule invasion, and TNM staging(P>0.05). Conclusion: The value of BRAF V600E mutation in the prognosis of PTC remains to be studied. BRAF V600E mutation is of value for pathological diagnosis of PTC.-
