BRAF and metastatic malignant neoplasm in the lymph nodes: Univariate and multivariate analyses with lymph node metastasis as the dependent variable demonstrated that Gender (B=0.840,P=0.011), Psammoma Bodies (B=1.144,P=0.040), Non-BRAF mutation (B=‐1.544,P=0.021), Tumor Size (B=0.456,P=0.047), and SIRI (B=0.380,P=0.011) were significantly associated with lymph node metastasis (p < 0.05 for all).
