OBJECTIVES: To investigate the significant predictors of contralateral upper tract recurrence after radical nephroureterectomy for upper tract urothelial carcinoma.
METHODS: Between January 2001 and December 2015, 548 patients with upper tract urothelial carcinoma who underwent radical nephroureterectomy in a single institution were included in this retrospective cohort study. Several clinicopathological characteristics and outcomes were explored. The crucial end-point was the diagnosis of contralateral upper tract recurrence after radical nephroureterectomy.
RESULTS: Of the 548 patients, the median age was 68 years (range 24-93 years), and the median follow-up time after radical nephroureterectomy was 41 months (range 8-191 months). Contralateral upper tract recurrence occurred in 28 patients (5.1%). The median time period between radical nephroureterectomy and contralateral upper tract recurrence was 15.4 months (range 3.4-52.4 months). In the multivariate analysis, preoperative estimated glomerular filtration rate <30 mL/min/1.73 m2 (hazard ratio 3.08, P = 0.003) and tumor multifocality (hazard ratio 2.16, P = 0.043) were independent risk factors.
CONCLUSION: Preoperative estimated glomerular filtration rate <30 and tumor multifocality are significant predictors of contralateral upper tract recurrence after radical nephroureterectomy for upper tract urothelial carcinoma.
