BRAF and metastatic malignant neoplasm in the lymph nodes: Univariate analysis showed that the proportion of multiple foci, bilateral foci, diameter >0.5 cm, and intermediate-to-high risk stratification for recurrence of the LNM group was significantly higher than those of the non-lymph node metastasis group (all p<0.05), and there were no statistically significant differences in BMI≥25 kg/m2, extracapsular invasion, HT, BRAF gene mutation rate, distant metastasis, and TNM stage (all p<0.05).
