超声引导下粗针穿刺活检对甲状腺结节的诊断价值

Diagnostic value of ultrasound-guided core needle biopsy for thyroid nodules

目的探讨超声引导下粗针穿刺活检(UG-CNB)对甲状腺良、恶性肿瘤的鉴别价值。方法选取2014年4月至2016年4月该院甲状腺结节住院患者216例(结节数327个)作为研究对象,以术后组织病理为对照,分析UG-CNB对良、恶性肿瘤的诊断准确性。结果术后组织病理显示,327个结节中良性193个(59.02%),恶性134个(40.98%)。UG-CNB诊断为良性结节192个,恶性结节135个,诊断灵敏度、特异度、准确度、阳性似然比、阴性似然比分别为94.78%、95.85%、95.41%、22.84、0.05。结论 UG-CNB对甲状腺良、恶性肿瘤诊断准确性较高,可为临床治疗提供有价值的信息,值得推广运用。

Objective To evaluate the differentiation value of ultrasound-guided core needle biopsy（UG-CNB）for benign and malignant thyroid tumor.Methods A total of 216 hospitalized patients（327thyroid nodules）in the hospital from April 2014 to April 2016 were selected as the research subjects.The accuracy of UG-CNB for diagnosing benign and malignant tumors was analyzed with the postoperative histopathology results as the control.Results The postoperative histopathological results showed that 193nodules（59.02%）were benign and 134nodules（40.98%）were malignant among 327 thyroid nodules.UG-CNB diagnosed 192 benign nodules and 135 malignant nodules.The sensitivity,specificity,accuracy,positive likelihood ratio and negative likelihood ratio of UG-CNB diagnosis were 94.78%,95.85%,95.41%,22.84,and 0.05 respectively.Conclusion UG-CNB has high diagnostic accuracy in benign and malignant thyroid nodules,can provide valuable information for clinical treatment and is worth application and promotion.
