Analysis results showed that the expression of VEGF in CNC was only correlated with lymph node metastasis (p < 0.05), and it is related to lymph node metastasis, clinical stage, and pathologic stage in BLBC (p < 0.05) (Figures 3I–K shows the negative expression of BRCA1, HIF-1α and VEGF in the control group). This evidence concerns the gene HIF1A and metastatic malignant neoplasm in the lymph nodes.
