External validation and comparison of nomograms for prediction of long-term disease recurrence and survival for bladder cancer patients who undergo radical cystectomy

Key Points

• The research aims to validate and compare the effectiveness of nomograms in predicting long-term outcomes for bladder cancer patients.
• Evaluated multiple nomograms for predicting disease recurrence and survival.
• Conducted an external validation of the nomograms.
• Assessed accuracy in predicting 5-year disease-free survival (DFS) and cancer-specific survival (CSS).
• All nomograms demonstrated comparable accuracy in predicting 5-year DFS and CSS.
• Findings support the use of these nomograms in clinical decision-making.
• Identified limitations for individual patient-specific application.
