Answer

In the future, treatment selection for muscle-invasive bladder cancer is likely to be based on testing of tumors for biomarkers that indicate treatment sensitivity. Patients with resistant tumors would be offered upfront cystectomy, while those with chemoradiation-sensitive tumors would be offered bladder-preserving therapy, with regimens selected on the basis of genetic analysis. [82] For example, presence of the MRE11A single-nucleotide polymorphism rs1805363 has been associated with worse cancer-specific survival after radiation therapy, with a gene-dosage effect observed, but not after cystectomy.
