目的
2
探讨剪切波弹性成像(shear wave elastography,SWE)与细针穿刺洗脱液甲状腺球蛋白(fine-needle aspiration washout thyroglobulin,FNA-Tg)对甲状腺乳头状癌侧颈部淋巴结转移的诊断价值。
方法
2
回顾性分析159例经病理证实为甲状腺乳头状癌(papillary thyroid carcinoma,PTC)的患者资料,对颈部211枚可疑淋巴结进行常规超声、SWE参数平均值(E
mean
)、FNA-Tg检查,以术后病理结果为金标准,比较各检测方法的诊断效能。
结果
2
①SWE E
mean
转移组[(50.96±27.66) kPa
]
高于非转移组[(32.20±17.34) kPa
]
,差异有统计学意义(
t
=8.761,
P<
0.01)。受试者工作特征(receiver operating characteristic,ROC)曲线分析表明,SWE E
mean
最佳诊断阈值为40.42 kPa时对PTC颈部淋巴结转移预测价值较高,曲线下面积(area under the curve,AUC)为0.849(95%CI=0.795~0.902,
P
<
0.01)。②与SWE E
mean
比较,联合法敏感度、特异度、准确度、阳性预测值及阴性预测值均显著提高(
χ

=7.724、28.230、35.094、21.731、9.890,
P=
0.005、
<
0.000、

0.000、
<
0.000、0.002)。与FNA-Tg比较,联合法敏感度、特异度、准确度、阳性预测值及阴性预测值也显著提高(
χ
2
=7.724、6.014、13.526、6.137、7.602,
P=
0.005、0.014、
<
0.000、0.013、0.006)。③在淋巴结有囊性变和无囊性变时,SWE E
mean
的准确度分别为53.8%和79.8%,差异有统计学意义(
χ
2
=4.819,
P
=0.028);FNA-Tg的准确度分别为92.3%和87.4%,差异无统计学意义(
χ
2
=0.275,
P
=0.600)。
结论
2
FNA-Tg诊断PTC转移淋巴结的准确度较高,且不受淋巴结有无囊性变的影响,与SWE E
mean
联合后可显著提高诊断效能。
Objective
2
To investigate shear wave elastography(SWE)and fine-needle aspiration washout thyroglobulin(FNA-Tg)in the diagnosis of cervical lymph node metastasis of thyroid papillary carcinoma.
Methods
2
The data of 159 patients with papillary thyroid carcinoma(PTC) confirmed by pathology were analyzed retrospectively,and 211 suspected lymph nodes in the neck were examined by ultrasonic examination,SWE E
mean
and FNA-Tg. The diagnostic efficacy of each method was compared with the postoperative pathological results as the gold standard.
Results
2
①The SWE E
mean
metastasis group [(50.96±27.66) kPa
]
was significantly higher than the non-metastasis group [(32.20±17.34) kPa
]
,with a statistically significant difference(
t
=8.761,
P
<
0.01). The receiver operating characteristic(ROC) curve analysis showed that SWE E
mean
optimal diagnostic threshold of 40.42 kPa had a higher predictive value for cervical lymph node metastasis of PTC,with an area under the curve(AUC) of 0.849(95%CI=0.795-0.902,
P
<
0.01). ②Compared with SWE E
mean
,the sensitivity,specificity,diagnostic value,positive predictive value and negative predictive value were significantly increased(
χ
2
=7.724,28.230,35.094,21.731,9.890;
P=
0.005,
<
0.000,
<
0.000,
<
0.000,0.002). Compared with FNA-Tg,the sensitivity,specificity,diagnostic value,positive predictive value and negative predictive value of the combined method were significantly increased(
χ
2
=7.724,6.014,13.526,6.137,7.602;
P=
0.005,0.014,
<
0.000,0.013,0.006). ③The accuracy of SWE E
mean
was 53.8% with and 79.8% without cystic changes in lymph nodes,respectively,with a statistical significance(
χ
2
=4.819,
P
=0.028). The accuracy of FNA-Tg was 92.3% and 87.4%,respectively,with no significant difference(
χ
2
=0.275,
P
=0.600).
Conclusion
2
FNA-Tg has a high accuracy in the diagnosis of PTC metastatic lymph nodes,and is not affected by the presence or absence of cystic changes in lymph nodes. The combination of SWE E
mean
and FNA-Tg can significantly improve the diagnostic efficiency.
