The Cancer Genome Atlas project has identified and confirmed several important molecular alterations that form the basis for tumorigenesis and disease progression in muscle-invasive bladder cancer. Profiling studies also have reported on validated biomarker panels that predict prognosis and may be used to identify patients who require more aggressive therapy. This article describes the major molecular alterations in muscle-invasive urothelial carcinoma, and how several of these are being investigated as targets for novel therapeutics. It also highlights studies that identify biomarkers for platinum sensitivity, and efforts to integrate targeted therapeutics and companion theranostics for personalized treatment of muscle-invasive bladder cancer.
Keywords: Clinical trials; Mutation analysis; Prognosis; Targeted therapy; Urothelial carcinoma; Whole-genome sequencing.
