Survival of 1082 patients with ER + /HER2- breast cancer based on EERES, as determined by GSVA using the Hallmark Estrogen Response Early MSigDB gene set. (a) Scatter plot of ESR1 gene expression and EERES of ER + /HER2- (blue) breast cancer and TNBC (yellow) tumor samples. (b) PFS and (c) OS durations of ER + /HER2- breast cancer and TNBC tumor samples, tested with log-rank tests and shown as Kaplan–Meier curves. ER + /HER2- breast cancer tumor samples were stratified into higher and lower EERES, as described in the Methods, and their (d) PFS and (e) OS durations are shown as Kaplan–Meier curves.
