HIF1A and metastatic malignant neoplasm in the lymph nodes: The low expression of FOXO3a was significantly correlated with clinical stage (P = 0.003), T stage (P = 0.011), lymph node metastasis (P = 0.003), and distant metastasis (P = 0.030), and overexpression of HIF-1α was significantly correlated with T stage (P = 0.026), lymph node metastasis (P = 0.002), and distant metastasis (P = 0.010).
