The remainder of signatures are published gene expression-based signatures from Calabro et al. [19] that are predictive of ER-negative breast cancer prognosis, a five-gene signature from Ascierto et al. [20] that predicts recurrence-free survival across breast cancer subtypes, and the B-cell, IL8 and combined signatures to predict prognosis of TNBC [21]. The gene discussed is CXCL8; the disease is breast cancer.
