US-FNAC检测甲状腺结节伴钙化患者的病理阳性率、血流信号及与甲状腺癌病理特征的相关性研究

Correlation between Pathological Positive Rate,Blood Flow Signal and Pathological Features of Thyroid Carcinoma in Patients with Thyroid Nodules and Calcification Detected by US-FNAC

目的:探讨US-FNAC检测甲状腺结节伴钙化患者的病理阳性率、血流信号及与甲状腺癌病理特征的相关性。方法:选取2015年10月-2017年10月在本院接受手术治疗的甲状腺结节患者100例(结节109个),患者均接受US-FNAC检查,统计分析患者钙化情况、病理阳性率、局部血流信号情况及甲状腺癌病理特征。结果:本研究结节良性69个,恶性40个,微小钙化型结节恶性率均显著高于其他三种钙化类型(P<0.05),+++级血流信号强度结节恶性率均显著高于其他三种血流信号(P<0.05);微小钙化的存在与患者甲状腺包膜侵犯、淋巴结转移和结节直径有关(P<0.05)。结论:US-FNAC检测可以结合结节钙化类型与血流信号预测结节病理阳性率,且结节钙化与甲状腺癌病理特征有关。

Objective：To explore the correlation between pathological positive rate,blood flow signal and pathological features of thyroid carcinoma in patients with thyroid nodules and calcification detected by US-FNAC.Method： A total of 100 patients（109 nodules） with thyroid nodules underwent surgical treatment in our hospital from October 2015 to October 2017 were selected,they were examined by US-FNAC.The calcification,positive rate of pathology,local blood flow signal and pathological features of thyroid carcinoma were analyzed.Result：There were 69 benign nodules and 40 malignant nodules.The malignant rates of microcalcified nodules were significantly higher than those of the other three calcifications（P〈0.05）.The malignant rate of blood flow signal intensity of ＋＋＋ level were significantly higher than those of the other three blood flow signals（P〈0.05）.The presence of microcalcification was associated with thyroid capsule invasion,lymph node metastasis and nodal diameter（P〈0.05）.Conclusion：US-FNAC can predict the positive rate of nodule pathology by combining nodule calcification type and blood flow signal,and nodule calcification is related to the pathological characteristics of thyroid carcinoma.
