摘要
目的 探讨彩色多普勒超声检查、超声引导下细针穿刺细胞学检查(US-FNAC)联合BRAF^(V600E)基因检测对微小甲状腺结节的诊断价值。方法 选取中高风险微小甲状腺结节患者103例为研究对象。患者行甲状腺影像报告和数据系统(TI-RADS)分级,术前均行彩色多普勒超声检查、US-FNAC及丝氨酸/苏氨酸特异性激酶突变基因V600E(BRAF^(V600E))检测。术后根据病理结果计算并比较单独检测和三者联合检测的敏感性、特异性和准确性,分析诊断效能。结果 超声检查显示,不同性质结节的纵横比、结构、回声、钙化及边缘情况比较,差异均有统计学意义(P<0.05)。良性结节和恶性结节垂直位、低回声、点状强回声或微钙化及边缘不规则生长的诊断结果比较,差异有统计学意义(P<0.05)。103例研究对象中,US-FNAC检查诊断为Ⅴ、Ⅵ级的患者63例(共98个结节,其中67个恶性),占比61.2%;Ⅲ、Ⅳ级的患者26例(共32个结节,其中14个恶性),占比25.2%;Ⅱ级的12例(共12个结节,无恶性),占比11.7%;Ⅰ级的2例(共2个结节,其中1个恶性),占比1.9%。BRAF^(V600E)基因检测有72例发生突变(共111个结节,其中76个恶性),占比69.9%;无突变患者31例(共33个结节,其中6个恶性),占比30.1%。超声检查、US-FNAC检查、BRAF^(V600E)基因检测的敏感性、特异性和准确性分别为75.3%、62.5%、73.0%, 79.5%、68.8%、77.5%与93.2%、68.8%、88.8%;三者联合诊断的敏感性、特异性和准确性均最高,分别为97.3%、75.0%、93.3%。联合诊断的敏感性、特异性和准确性高于单独检测,差异有统计学意义(P<0.05)。结论 联合检测可提高对甲状腺乳头状微小癌的检出率,有助于微小结节精准的术前评估。
Objective To investigate the diagnostic value of color Doppler ultrasound,ultrasound-guided fine needle aspiration cytology(US-FNAC)combined with BRAF^(V600E) gene detection in small thyroid nodules.Methods A total of 103 patients with moderate or high risk small thyroid nodules were selected as study subjects.The Thyroid Imaging Reporting and Data System(TI-RADS)grading,preoperative color doppler ultrasound US-FNAC and silk/threonine specific kinase mutant gene V600E(BRAF^(V600E))detection were performed.The sensitivity,specificity and accuracy of each examination alone and their combination were compared according to the pathological results,and the diagnostic performance was analyzed.Results The ultrasound examination showed that there were statistically significant differences in aspect ratio,structure,echo,echoes,calcification and marginal growth of nodules of different nature(P<0.05).Of the 103 subjects,63 cases(98 nodules with 67 malignant ones)were diagnosed as grade V or VI by US-FNAC examination,accounting for 61.2%.There were 26 patients with gradeⅢandⅣ(32 nodules with 14 malignant ones),accounting for 25.2%.There were 12 cases of gradeⅡ(12 nodules in total without malignancy),accounting for 11.7%;there were 2 cases of gradeⅠ(2 nodules with one malignant nodule),accounting for 1.9%.BRAF^(V600E) gene examination showed that 72 cases(111 nodules,76 of which were malignant)was detected,accounting for 69.9%.There were 31 patients without mutation(33 nodules in total,6 of which were malignant),accounting for 30.1%.The sensitivity,specificity and accuracy of ultrasound examination,US-FNAC examination and BRAF^(V600E) gene test were 75.3%,62.5%,73.0%,respectively,79.5%,68.8%,77.5%,respectively and 93.2%,68.8%,88.8%,respectively.The sensitivity,specificity and accuracy of their combined diagnosis were the highest,which were 97.3%,75.0%and 93.3%,respectively.The sensitivity,specificity and accuracy of their combined diagnosis were higher than those of single detection(P<0.05).Conclusion Combined detection can improve the detection rate of thyroid papillary microcarcinoma,which is conducive to accurate preoperative evaluation of small nodules.
