It was concluded that the MMP14 expression of 33 tumors and the immune score (ImmuneScore) relationship showed a significant correlation (p < 0.05), as the expression of MMP14 and the immune score were positively related in BLCA, BRCA, CESC (cervical cancer), COAD, lymphoid neoplasm diffuse large B-cell lymphoma (DLBC), ESCA, GBM, HNSC, KICH, KIRP, LGG, LIHC, LUAD, LUSC, OV, PAAD, pheochromocytoma and paraganglioma (PCPG), PRAD, READ, STAD, and THCA. This evidence concerns the gene MMP14 and bladder transitional cell carcinoma.
