Hou J, et al. - Via retrospectively analyzing clinicopathologic feature data of 427 individuals with right or double lobes who had surgery between January 2014 to August 2019 in the Department of General Surgery, Shanghai Jiao Tong University Affiliated Sixth People’s Hospital, researchers examined the risk factors of lymph node posterior to the right recurrent laryngeal nerve (LN-prRLN) metastasis in papillary thyroid carcinoma. In 96 patients, LN-prRLN metastasis was identified. According to univariate analysis, age, right-side tumor diameter, capsular invasion, comorbid adenoma, and VIa compartment LN metastasis were significantly related to LN-prRLN metastasis. Multivariate logistic regression analysis demonstrated that independent risk factors for LN-prRLN metastasis were right-side tumor diameter, capsular invasion, and VIa compartment LN metastasis. The authors recommended that the incidence of LN-prRLN metastasis can not be overlooked and prophylactic LN-prRLN dissection should be performed in patients with right-side tumor diameter ≥ 1.25 cm, capsular invasion, and VIa compartment LN metastasis.
