To expand on our understanding of the role of GBP-2 in human breast cancer, we asked whether GBP-2 correlated with improved recurrence-free survival (RFS), overall survival (OS), and distant metastasis-free survival (DMFS) in a series of gene array studies of all breast cancer types, all hormone status, all grades, and all node status (Figure 1). Here, GBP2 is linked to breast cancer.
