Additionally, patients with DLBC who had high levels of MMP9 had better survival rates (P=0.017), while high MMP9 in patients with ACC, BLCA, KIRC, and LIHC was associated with poor OS (P=0.003, p=0.03, P=0.001, and P=0.009, respectively). This evidence concerns the gene MMP9 and bladder transitional cell carcinoma.
