摘要:

目的 探讨超声引导下细针穿刺细胞学(UG-FNAC)联合BRAFV600E基因突变检测在美国放射医学会甲状腺超声影像报告和数据系统(ACR-TIRADS)4类结节中的诊断价值。方法 回顾性分析2018年01月至2021年06月在扬州大学附属苏北人民医院经超声检查评估为ACR-TIRADS4类的甲状腺结节471例,所有病例均行UG-FNAC及BRAFV600E检测并行手术治疗,采用液基薄层细胞学处理UG-FNAC标本及荧光定量PCR法检测BRAFV600E突变,以术后病理为金标准构建UG-FNAC、BRAFV600E检测以及两者联合诊断ACR-TIRADS4类结节的受试者工作特征曲线,评估诊断效能。结果 UG-FNAC或BRAFV600E突变检测诊断TIRADS4类结节的敏感度(Se)和特异度(Sp)分别为75.8%、98.8%和56.7%、98.8%,两者联合诊断的Se和Sp分别为95.6%和98.3%。UG-FNAC联合BRAFV600E突变检测的曲线下面积(AUC)(0.970)高于单独应用UG-FNAC(0.873)和BRAFV600E检测(0.778)(P<0.05),联合诊断TIRADS 4a、4b、4c类结节的AUC分别为0.961、0.972和0.981。结论 UG-FNAC联合BRAFV600E检测能显著提高ACR-TIRADS4类结节术前诊断的准确率。

Abstract:

Objective To evaluate the diagnostic value of ultrasound-guided fine needle aspiration cytology (UG-FNAC) combined with BRAFV600E gene detection for American College of Radiology-thyroid imaging reporting and data system (ACR-TIRADS) category 4 thyroid nodules(TN). Methods A retrospective analysis involved 471 patients evaluating TN of ACR-TIRADS 4 by ultrasound examination, who admitted to Northern Jiangsu People's Hospital Affiliated to Yangzhou University from January 2018 to June 2021, and the patients underwent preoperative UG-FNAC and BRAFV600E gene detection. Thin-layer (liquid-based) cervical cytology and fluorescence quantitative PCR were used for detecting puncture specimens and BRAFV600E mutation, respectively. Using postoperative pathology as the gold standard, the receiver operating characteristic (ROC) curve of TN (ACR-TIRADS 4) was constructed by UG-FNAC and BRAFV600E detection and the combined diagnosis of the two, and the diagnostic efficacy was evaluated. Results The sensitivity(Se) and specificity(Sp) of TN (TIRADS 4) using UG-FNAC or BRAFV600E gene detection were 75.8%, 98.8% and 56.7%, 98.8%, respectively. Se and Sp using the combination of both were 95.6% and 98.3%, respectively; areas under curve (AUC) using the combination (0.970) was higher than UG-FNAC (0.873), or BRAFV600E detection alone (0.778)(P<0.05); AUC of TN (TIRADS 4a, 4b, and 4c ) using the combination were 0.961, 0.972, and 0.981, respectively. Conclusion UG-FNAC combined with BRAFV600E gene detection can effectively improve the accuracy of preoperative diagnosis of TN (ACR-TIRADS 4).
