超声对预测甲状腺乳头状癌颈部淋巴结转移的研究进展

Research advances of ultrasound in predicting cervical lymph node metastasis of papillary thyroid cancer

颈部淋巴结转移为甲状腺乳头状癌(Papillary thyroid carcinoma,PTC)复发和远处转移危险因素,术前明确诊断可为临床手术方式的选择提供充分依据。常规超声对评估PTC颈部淋巴结转移具有一定优势,但诊断特异度高而敏感度低,尤其对中央区淋巴结转移。PTC原发癌结节的常规超声、超声造影及弹性成像特点对提高PTC颈部淋巴结转移的预测可能具有较高诊断价值。

Cervical lymph node metastasis of papillary thyroid carcinoma （PTC） is a risk factor for recurrence and distant metastasis. Preoperative diagnosis has a very significant impact on surgical type. Conventional ultrasound has a certain advantage in assessing cervical lymph node metastasis with high specificity, but the sensitivity is relatively low, especially on central compartment lymph node metastasis. PTG nodule characteristics of conventional ultrasound, contrast-enhanced ultrasonography and ultrasonic elastography may serve as a useful tool to predict cervical lymph node metastasis in PTC.
