Based on the DNA microarray data gathered in the Breast Cancer Gene-Expression Miner v4.7 resource, OS, DFS, and DMFS were negatively associated with CEMIP expression level (Figures 2D–F, p < 0.05) by enrolling all BC patients and OS was also negatively correlated with CEMIP expression level in ER/PR-positive BC patients (Figure 2G, p < 0.05), whereas no significant correlation existed between patients’ DFS, DMFS, and the expression level of CEMIP (Supplementary Figures S3A,B, p > 0.05) as well as the OS, DFS, and DMFS in all ER/PR-negative BC patients (Supplementary Figures S3C–E, p > 0.05). Here, ESR1 is linked to breast cancer.
