As shown in Table 3, EGFR positivity was significantly correlated with lymph node metastasis (P = 0.010) and UICC stage (P = 0.021); however, there was no significant correlation between EGFR positivity and patient’s age (P = 0.387), histological type (P = 0.14) or lymphovascular infiltration (P = 0.197). Here, EGFR is linked to metastatic malignant neoplasm in the lymph nodes.
