The Usefulness of the Modified Frailty Index for Muscle-Invasive Bladder Cancer Patients Treated with Radical Cystectomy.

Background: Radical cystectomy is still the gold standard for muscle-invasive bladder carcinoma (MIBC) treatment. In order to reduce postoperative complications, multimodality bladder-sparing therapies could be a good alternative. Studies in various malignancies have shown that the modified Frailty Index (mFI) may be more useful for identifying high-risk patients.
