However, FOXK1 expression significantly correlated with TNM stage (P = 0.002), differentiation (P = 0.000), AJCC Stage I/II (P = 0.031), AJCC Stage III/IV (P = 0.04), tumor size (P = 0.019) and lymph node metastasis (P = 0.013). This evidence concerns the gene FOXK1 and metastatic malignant neoplasm in the lymph nodes.
