Fig. 2: Individual gene expression levels of the 16 cancer genes from the 21-gene RS in breast cancer patients with IDC or IDC/DCIS.

Genes are grouped on the basis of gene function and correlated expression. Proliferation group genes include Ki67, STK15, Survivn, CCNB1, and MYBL2. Invasion group genes include MMP11 and CTSL2. HER2 group genes include GRB7 and HER2. ER Proliferation group genes include ER, PR, BCL2, and SCUBE2. Significant P-value (<0.05) are in bold.
