Survival nomogram for patients with upper tract recurrence after resection for localized bladder urothelial carcinoma

Abstract

Aim: To develop a survival nomogram for patients with upper tract recurrence (UTR) after resection for localized bladder urothelial carcinoma (BUC). Methods: The data of 361 patients with UTR after resection for BUC registered in the Surveillance, Epidemiology, and End Results database were retrospectively analyzed. The nomogram was established using the Fine and Gray method and its predictive accuracy was assessed using the concordance index. The nomogram was calibrated by comparing the predicted and actual survival. Results: The concordance index of the nomogram was 0.746 (95% CI: 0.733–0.759). Excellent agreement was observed between the predicted and actual survival in all calibration plots. Conclusion: This study describes the first survival nomogram for patients experienced UTR after resection for BUC.
