Abstract

PURPOSE: To determine whether carcinoma in situ (CIS) is a sufficient measure of minimal residual disease (MRD) in non-muscle-invasive bladder cancer (NMIBC) and evaluate alternative measures of MRD. EXPERIMENTAL DESIGN: We evaluated the concordance of CIS on transurethral resection of bladder tumor (TURBT) and radical cystectomy (RC) to determine eradication rates of clinical CIS (cCIS) by TURBT…
