In basal-like breast cancer, mRNA expression of S100A10 (Fig. 4A: HR = 2.2 95%CI: 1.23–3.92, p = 0.0061), S100P (Fig. 4C: HR = 2.01, 95%CI: 1.14–3.56, p = 0.0139) and S100Z (Fig. 4D: HR = 2.15, 95%CI: 0.98–4.7, p = 0.0491) were correlated to worse OS. This evidence concerns the gene S100A10 and breast cancer.
