Abstract: Objective The Objective of this study was to investigate the relationship between preoperative serum thyroglobulin(PS-Tg)and lymph node metastasis(LNM)in papillary thyroid carcinoma(PTC). Methods This study included 283 clinical and pathological data of PTC patients who underwent thyroidectomy from October 2021 to September 2022 and were confirmed by postoperative pathology.The relationship between PS-Tg and PTC LNM was analyzed by univariable and multivariable logistic regression,the nomogram was used to quantify the relationship between them,and the optimal cut-off value was determined by receiver operating characteristic(ROC)curves. Results The level of PS-Tg in the PTC combined with LNM group was higher than that in the pure PTC group(P<0.05).Univariable and multivariable logistic regression analyses showed that elevated PS-Tg level might be an independent risk factor for LNM of PTC,and the increase of PS-Tg level could explain approximately 15% of the risk of LNM in PTC. Conclusion Elevated PS-Tg level may be a risk factor for cervical LNM in PTC patients,and it has a certain predictive value for preoperative LNM diagnosis.
