Likewise, the results from bc-GenExMiner also showed that higher expression of CXCL9 was associated with better DMFS (Supplementary Figures S2A, B, ER-, HR=0.66, P<0.01; ER+, HR=1.06, P=0.59) and OS (Supplementary Figures S2C, D, ER-, HR=0.67, P<0.01; ER+, HR=1.10, P=0.08); in the ER-negative group, while there was no significance in patients with ER-positive tumours, which was consistent with the results from the GOBO database (Supplementary Figures S2E–H, DMFS: ER-, P<0.01; ER+, P=0.85; OS: ER-, P<0.01; ER+, P=0.48). The gene discussed is CXCL9; the disease is neoplasm.
