As shown in Table SII, the expression of NCOA7 was significantly higher in patients with TNBC than in patients with N-TNBC who were aged >50 years (P=0.023), with a tumor size of >3 cm (P=0.007) and those who had lymph node metastasis stages N1-3 (P=0.023). This evidence concerns the gene NCOA7 and metastatic malignant neoplasm in the lymph nodes.
