To develop a predictive model, we compared the expression values of 1027 inflammation‐related genes18, 19 and obtained three significant mRNAs (TBX21, TGIF2, and CYCS) between 669 breast cancer patients from TCGA and 15 normal controls from GSE8977 (P < 0.05; Figure 1A). This evidence concerns the gene TGIF2 and breast cancer.
