Risk factors for lymph node posterior right recurrent laryngeal nerve metastasis of papillary thyroid carcinoma

Abstract

Abstract: Objective To investigate the risk factors for lymph node posterior right recurrent laryngeal nerve (LN-prRLN) metastasis of papillary thyroid carcinoma (PTC). Methods Clinicopathologic data of 424 patients with PTC who had right or bilateral thyroidectomy were analyzed retrospectively between January 2014 and August 2019 in our department. Risk factors for LN-prRLN metastasis were analyzed by χ² test and Logistic regression model. Results LN-prRLN metastasis had been detected in 96 (22.64%) patients. Univariate analysis showed that the factors including age, tumor diameter, capsular invasion and right Ⅵa lymph node metastasis were significantly related with LN-prRLN metastasis (all P<0.001). It was shown by Logistic regression analysis that 3 factors of tumor diameter 1 cm and larger, capsular invasion and right Ⅵa lymph node metastasis were independent risk factors for LN-prRLN metastasis (all P≤0.001). Conclusions The rate of LN-prRLN metastasis was 22.64% in this study. It should be paid more attention to LN-prRLN dissection when tumor diameter 1 cm and larger, capsular invasion and right Ⅵa lymph node metastasis were found in PTC patients.
