CEACAM5 and metastatic malignant neoplasm in the lymph nodes: As expected, clinicopathologic features including TNM stage (P < 0.0001), lymph node metastasis (P < 0.0001), depth of invasion (P = 0.011), preoperative serum CEA levels (P = 0.001) significantly influenced recurrence of colon adenocarcinoma, whereas intravascular embolus, histological differentiation, gender, age, and tumor size didn't affect recurrence of tumors (P > 0.05).
