【摘要】：目的探討甲狀腺影像學(xué)報告及數(shù)據(jù)系統(tǒng)(TI-RADS)分級聯(lián)合超聲彈性成像(UE)在甲狀腺微小乳頭狀癌(PTMC)術(shù)前診斷中的臨床價值。方法回顧性分析2013年6月至2015年6月甘肅省腫瘤醫(yī)院行超聲檢查的96例(138個惡性結(jié)節(jié))PTMC病人和78例(142個微小良性結(jié)節(jié))甲狀腺病病人的臨床資料。以病理學(xué)檢查結(jié)果為金標(biāo)準(zhǔn),比較TI-RADS分級、UE及兩者聯(lián)合診斷PTMC的敏感度、特異度、陽性預(yù)測值、陰性預(yù)測值及準(zhǔn)確率。計算三種方法診斷PTMC的受試者工作特性(ROC)曲線下面積。根據(jù)結(jié)節(jié)直徑將PTMC病人分為5 mm組和≤5 mm組,比較各診斷方法的準(zhǔn)確率。結(jié)果 TI-RADS分級聯(lián)合UE診斷PTMC的敏感度、特異度、陽性預(yù)測值、陰性預(yù)測值及診斷準(zhǔn)確率(93.5%、97.2%、97.0%、93.9%及95.4%)均高于UE(87.7%、93.7%、93.1%、88.7%及90.7%)和TI-RADS分級(80.4%、87.3%、86.0%、82.1%及83.9%)。TI-RADS分級、UE及二者聯(lián)合診斷PTMC的ROC曲線下面積分別為0.873、0.937、0.972,UE的診斷價值高于TI-RADS分級(P0.05),兩種方法聯(lián)合診斷價值高于單一方法(P0.05)。三種方法對≤5 mm和5 mm PTMC的診斷準(zhǔn)確率分別為72.8%、90.1%、92.7%和89.9%、92.3%、97.2%,UE對于≤5 mm PTMC的診斷準(zhǔn)確率明顯高于TI-RADS分級(P0.05)。結(jié)論 UE對PTMC的術(shù)前診斷價值高于TI-RADS分級,尤其對于≤5 mm的PTMC診斷準(zhǔn)確率更高,二者聯(lián)合有助于提高PTMC術(shù)前診斷準(zhǔn)確率。
[Abstract]:Objective to investigate the application of TI-RADS classification combined with ultrasound elastography (UEE) in PTMC of thyroid micropapillary carcinoma. Methods from June 2013 to June 2015, 96 patients (138 malignant nodule PTMC) and 78 patients with PTMC underwent ultrasound examination in Gansu Provincial Cancer Hospital were retrospectively analyzed. Clinical data of 142 patients with thyroid disease. To compare the sensitivity, specificity and positive predictive value of TI-RADS grade UE and their combination in the diagnosis of PTMC. The negative predictive value and accuracy were calculated. The area under the curve was calculated for the three methods to diagnose PTMC. According to the diameter of nodules, the patients with PTMC were divided into 5 mm group and 鈮，
