CEACAM5 and metastatic malignant neoplasm in the lymph nodes: In the univariate analysis, RDW-SD ≤ 40.2 fl (p = 0.047), T3-T4 stage (p = 0.017), lymph node metastasis (p < 0.001), multiple tumors (p = 0.018), preoperative CEA > 5 ng/mL (p < 0.001), ALT > 50 U/L (p = 0.019) and blood loss ≥ 300 mL (p = 0.008) were associated with worse DFS.
