Urologe A. 2020 Nov 26;: Authors: Erben P, Becker C, Tsaur I, Stope MB, Todenhöfer T, Fachgruppe Molekulare Urologie der Arbeitsgruppe urologische Forschung (AuF) der Deutschen Gesellschaft für Urologie Abstract Advanced and metastatic stages of bladder cancer are associated with a poor prognosis. Therapy options are currently limited to systemic therapy with chemo- and immunotherapeutics. In order to improve individual therapy and especially to achieve a more favorable prognosis for these patients, intrinsic molecular subtypes have recently been identified in urothelial carcinoma of the bladder. This review article presents the latest developments, background, and clinical relevance of molecular subtypes in urothelial carcinoma of the bladder. The existing literature and current study data were analyzed to present and evaluate the different molecular classification systems. A focus was placed on the possible therapeutic implications of these molecular subtypes. Although promising progress has been made in the molecular subtyping of urothelial carcinoma, this classification has not yet found its way into clinical application. Multicenter prospective studies with standardized study protocols are still lacking. Previous studies differ in molecular markers, sample collection and preparation procedures, and analytical protocols. Standardiz...
