[Report from the 9th symposium of the German Association for Bladder Cancer Research]

The annual symposium of the German Research Association for Bladder Carcinoma (DFBK) was organized on February 7th and 8th, 2020, in Düsseldorf. On the first day, eight international guest speakers invited by the DFBK and the Department of Urology of the Heinrich Heine University Düsseldorf presented the current state of research on bladder cancer (BC). Topics were genomic changes and molecular classification in non-muscle-invasive and muscle-invasive BC, prospects and limits of proteome technology in urine diagnostics, function of chromatin regulators in bladder carcinogenesis, cellular reactions to aneuploidy, organoid technology and biobanking, as well as novel aspects of immunotherapy for BC. The second day was dedicated to new results and ideas of the DFBK members on BC pathomechanisms, diagnostics and therapeutic approaches, and most importantly, discussions on the further development of collaborative projects.
