ERCC8 and metastatic malignant neoplasm in the lymph nodes: Expression of ERCC8 was statistically higher in patients with TNM stage I-II in comparison to stage III-IV (P < 0.001) (P < 0.001 for T stage; P = 0.002 for lymph node metastasis), and was higher in those with early-stage and small size (P = 0.031 and 0.007, respectively).
