DAB2 and metastatic malignant neoplasm in the lymph nodes: Low expression of Dab2 is not correlated with the patients’ age (P = 0.8692), gender (P = 0.5747) or histological classification (P = 0.5991), but has a close relationship with the differentiation (P < 0.0001), TNM stage (P = 0.006194) and lymph node metastasis (P = 0.00004, Table 1).
