Background:
This study aimed to investigate the impact of chronic kidney disease (CKD) on oncological outcomes in patients with upper tract urothelial cancer (UTUC) undergoing radical nephroureterectomy (RNU) in Taiwan.
Methods:
We conducted a retrospective cohort study using data from the Taiwan UTUC Collaboration database. 1590 patients who underwent RNU for UTUC were included in the analysis. Patients were categorized into 2 groups: those with adequate renal function and those with preoperative CKD. Overlap weighting was employed to address potential biases and baseline imbalances between the groups. Multivariable Cox regression models were used to analyze overall survival (OS), cancer-specific survival (CSS), and disease-free survival (DFS).
Results:
Preoperative CKD was significantly associated with poorer overall survival (HR, 1.372; 95% CI, 1.060-1.775; P = .016) compared to patients with adequate renal function. However, no significant association was observed between CKD and CSS or DFS. Further analysis revealed that patients with advanced CKD had a higher risk of UTUC-related death due to competing risks of non-UTUC-related mortality.
Conclusions:
Preoperative CKD in UTUC patients undergoing RNU emerged as the sole risk factor for an inferior OS, without impacting CSS and DFS.
