BIOMARKERS OF UROTHELIAL DAMAGE IN PATIENTS TREATED BY ADJUVANT INTRAVESICAL THERAPY

Introduction/Aim: Chemotherapy or BCG given intravesically to prevent recurrence after transurethral resection (TUR) of non-muscle invasive bladder cancer (NMI-BC) cause frequent, sometime severe, local toxicity. As a consequence, many patients do not complete the planned treatment (1). A major challenge for the urologists is to identify an early biomarker of urothelial damage to recognize and prevent local toxicity improving patient’s compliance. The purpose of our research was to investigate the relation between urothelial injury by intravesical treatment and the expression of potential biomarkers in urine and/or in barbotage solution. The urinary HB-EGF expression in interstitial cystiti…
