Higher MMP-9 expression levels were associated with shorter PFI in ACC (P = 0.002), uveal melanoma (UVM) (P = 0.009), KIRC (P = 0.001), thyroid carcinoma (THCA) (P = 0.025), and GBM (P = 0.021) and longer PFI in DLBC (P = 0.004) and CESC (P = 0.031) (Figures 5(a)–5(g)). The gene discussed is MMP9; the disease is glioblastoma.
