Recently, 14 urine proteins in voided urine samples and 10-protein bladder cancer biomarker panel, including IL8, MMP-9, MMP-10, SERPINA1, VEGFA, ANG, CA9, APOE, SDC1, and SERPINE1, were analyzed and validated in a large cohort [22,23,24,25]. This evidence concerns the gene SERPINA1 and urinary bladder carcinoma.
