Abstract
OBJECTIVE: The aim of this study was to explore the risk factors that were associated with central lymph node metastases (CLNM) in papillary thyroid carcinoma (PTC) patients.
METHODS: A total of 180 patients with PTC who underwent surgery in our hospital between January 2014 and December 2016 were identified retrospectively. The relationship between clinicopathological factors and CLNM were analyzed by univariate and multivariate logistic regression.
RESULTS: The incidence of CLNM was 67.8% (122/180) in PTC patients. Univariate analysis showed that multifocality (p=0.002), HT (p<0.001) and LVI (p<0.001) were significant associated with CLNM. No significant associations were found between factors and CLNM, including age, gender, tumor size and ETE. Multivariate logistic regression analysis showed that multifocality (p=0.011), HT (p<0.001) and LVI (p<0.001) were independent predictors of CLNM in PTC patients.
CONCLUSIONS: Our study identified several independent risk factors predicting CLNM in PTC patients, such as multifocality, HT and LVI. The CLNM is very common in PTC patients, and routine prophylactic central neck dissection (PCND) may recommended in PTC patients with those risk factors of CLNM.
