EGFR and metastatic malignant neoplasm in the lymph nodes: Multivariate analysis revealed that EGFR expression was an independent prognostic factor (HR, 2.67; 95% CI, 1.52–4.69; P=0.0006), along with mass-forming macroscopic group (HR, 2.96; 95% CI, 1.06–8.31; P=0.0390), intrahepatic metastasis (HR, 2.91; 95% CI, 1.60–5.29; P=0.0005), and lymph node metastasis (HR, 1.96; 95% CI, 1.04–3.69; P=0.0375).
