摘要
目的:探讨甲状腺结节超声引导下细针穿刺细胞学(ultrasound-guided fine-needle aspiration cytology,US-G FNAC)检查过程中,针尖与结节移动状态对结节良恶性的诊断价值。方法:回顾性分析经手术病理证实的甲状腺结节患者140例,分为恶性组和良性组。恶性组患者80例,良性组患者60例,记录各结节的一般参数,包括结节大小(长径、短径)和部位(上极、中极、下极)。所有患者术前均进行甲状腺US-G FNAC检查。在US-G FNAC检查过程中,测量针尖移动距离(D1)、结节移动距离(D2)、针尖在结节中相对移动距离(D3),分析结节移动状态与良恶性的相关性。结果:两组一般参数比较差异无统计学意义(P>0.05)。D1、D2、D3与结节大小和部位均无相关性(P>0.05);D2、D3与结节良恶性显著相关(P<0.05);D1与良恶性结节无显著相关性(P>0.05)。与良性组比较,恶性组D2增大,D3减小,差异有统计学意义(P<0.05)。受试者工作特征(receiver operating characteristic,ROC)曲线分析显示,D2、D3诊断甲状腺结节良恶性的曲线下面积(area under curve,AUC)分别为0.951、0.938。结论:在US-G FNAC检查过程中,甲状腺结节移动状态与结节的良恶性存在相关性,可通过结节移动特征辅助鉴别甲状腺结节的良恶性。
Objective： To investigate the value of displacement characteristics of thyroid nodules during ultrasoundguide fine-needle aspiration cytology（US-G FNAC） examination in differential diagnosis of benign and malignant thyroid nodules. Methods： Totally 80 cases with malignant thyroid nodules and 60 cases with benign thyroid nodules were enrolled in the study. The final diagnosis was confirmed by pathology. All cases were examined by US-G FNAC before operation. The parameters including the displacement distance of needle tip（D1）, the displacement distance of nodule（D2） and displacement distance of needle tip relative to nodule（D3） were measured during US-G FNAC examination. Results： The general parameters were not significantly different between benign and malignant thyroid nodules（P〉0.05）. D1, D2 and D3 were not significantly correlated with the location and size of nodules（P〉0.05）, but D2 and D3 were significantly correlated with pathology results（P〈0.05）. Compared with benign nodules, D2 was significantly increased and D3 was significantly decreased in malignant nodules（P〈0.05）. The receiver operating characteristic（ROC） curve showed that the area under curve（AUC） of benign and malignant nodules was 0.951 and 0.938, respectively. Conclusion： The displacement characteristics of thyroid nodules during US-G FNAC examination are significantly correlated with pathology results, and can be a supplementary method in differential diagnosis of benign and malignant thyroid nodules.
