- To determine renal function eligibility for cisplatin-based chemotherapy using our experience with radical cystectomy (RC) patients.
Patients and Methods
- Using the Mayo Clinic Cystectomy Registry, we identified 768 patients treated with RC without neoadjuvant chemotherapy for urothelial carcinoma from 1980–2005.
- Glomerular filtration rate (GFR) was estimated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation and a value of ≥60 mL/min was considered eligible for cisplatin-based chemotherapy.
- Factors associated with change in GFR (from preoperative to 3-month postoperative) were assessed using linear regression.
- The median age was 68 years, while the median GFR was 60 mL/min both preoperatively and 3 months after RC.
- Overall, 405 (53%) patients had a GFR of <60 mL/min before surgery and 387 (50%) had a GFR of <60 mL/min at 3 months after RC.
- Patients with hydronephrosis (209 patients) had significantly lower preoperative GFRs than with patients without hydronephrosis (median 52 vs 62 mL/min, respectively; P < 0.001).
- Among the 363 patients with a GFR of ≥60 mL/min before RC, 91 (25%) had a decline in renal function to a GFR of <60 mL/min at 3 months after RC.
- In multivariable analyses, older age (P < 0.001), higher preoperative GFR (P < 0.001) and continent urinary diversion (P = 0.011) were significantly associated with a negative change in GFR after RC.
- Our results suggest that nearly half of patients undergoing RC are not eligible to receive perioperative cisplatin-based chemotherapy based on renal function status.
- About a quarter of patients eligible for cisplatin before surgery are no longer eligible after RC.
- Certain patient characteristics and surgical factors are more likely to experience a negative change in GFR after RC and should be counselled accordingly.
