Preoperative multiparametric ultrasound for the prediction of central lymph node metastasis in papillary thyroid carcinoma.

ABSTRACT:

Background

The preoperative assessment of lymph node metastasis (LNM) in papillary thyroid carcinoma (PTC) determines the surgical approach adopted for patients. Central lymph nodes are the most common site of metastasis and pose significant evaluation challenges. This study aimed to identify the preoperative multiparametric ultrasound (MULTI-US) risk factors for predicting central lymph node metastasis (CLNM) in PTC.

Methods

This retrospective study included 764 PTC patients with CLNM from our institution, who were randomly divided into a training set (n=534) and test set (n=230) at a ratio of 7:3. Univariable and multivariable analyses were conducted to identify significant predictors from the MULTI-US features, including B-mode, color Doppler imaging, contrast-enhanced ul
