Correlation analyses between STC‐1 and clinical characteristics revealed that the difference in STC‐1 expression levels was significantly associated with grade (p < 0.001), American Joint Committee on Cancer (AJCC) stage (p = 0.002), T stage (p = 0.002), N stage (p < 0.001), breast subtype (p < 0.001), estrogen receptor(ER) status (p < 0.001), progesterone receptor(PR) status (p < 0.001), HER‐2 status (p < 0.001), but was not associated with age, family history, histological type, Ki67, or vascular tumor emboli (p > 0.05) (Figure 1). This evidence concerns the gene STC1 and vascular neoplasm.
