Clinical trials

Invasive bladder cancer is managed with neoadjuvant therapy followed by bladder removal (cystectomy). Research shows that approximately 40% of patient will have no remaining cancer left in their bladder after completion of the initial systemic treatment, and perhaps could have avoided the surgery. However, currently physicians lack the ability to identify these patients. The investigators believe that by using advanced imaging (MRI), bladder biopsies and novel biomarkers that detect tumor DNA in blood, they can better identify participants without any remaining cancer after chemotherapy. This will make active surveillance of these participants safer. In this study, participants without evidence of residual cancer will be randomized to active surveillance vs conventional bladder treatment (bladder removal, or chemo-radiation of the bladder). This study will be a pilot randomized control trial (RCT), and if successful, it will transition to a larger phase 3 RCT.
