CDH12 and metastatic malignant neoplasm in the lymph nodes: Statistical results were shown in Tables 2 and 3; low expression of CDH12 was predominantly associated with tumor invasion depth (P = 0.02) and lymph node metastasis (P = 0.04) but has no relationship with patients’ age (P = 0.88), tumor size (P = 0.90), tumor histology (P = 0.60), and distant colonization (P = 0.36) (Table 3).
