High TGFBI expression was associated in Cox regression analyses with poor DSS in bladder cancer (p = 0.031), OS in brain cancer (p = 0.047), DFS, DMFS, and RFS in breast cancer (BRCA; all p < 0.05), DMFS in eye cancer (p = 0.010), OS and RFS in lung cancer (p < 0.001), and DRFS in soft tissue cancer (p < 0.001). Here, TGFBI is linked to breast cancer.
