The Impact

427 Background: Chronic kidney disease (CKD) is common in elderly patients with bladder cancer. In addition, increasing evidence has suggested that preoperative renal insufficiency indicates poor prognosis in bladder cancer. We aimed to evaluate the impact of CKD on oncologic outcomes in muscle-invasive bladder cancer patients who underwent radical cystectomy. Methods: A total of 581 patients who underwent radical cystectomy at four medical centers between January 1995 and February 2017 were examined retrospectively. We investigated oncologic outcomes, including progression-free, cancer-specific, and overall survival (PFS, CSS, and OS, respectively) stratified by preoperative CKD status (CKD vs. non-CKD). We performed a Cox proportional hazards regression analysis using inverse probability of treatment weighting (IPTW) to evaluate the impact of preoperative CKD on prognosis and developed the prognostic factor-based risk stratification nomogram. Results: Of the 581 patients, 215 (37%) were diagnosed with CKD before radical cystectomy. Before the background adjustment, PFS, CSS, and OS after radical cystectomy were significantly lower in the CKD group compared to the non-CKD group. Background-adjusted IPTW analysis showed that preoperative CKD was significantly associated with poor PFS, CSS, and OS after radical cystectomy. The nomogram for predicting 5-year PFS and OS probability showed significant correlation with actual PFS and OS ( c-index = 0.73 and 0.77, respectively). Conclusions: Muscle-invasive bladder cancer patients with preoperative CKD had a significantly lower survival probability than those without CKD.
