Upper tract urothelial recurrence following radical cystectomy for transitional cell carcinoma of the bladder: An analysis of 1,069 patients with 10-year followup

Purpose: Risk factors for upper tract recurrence following radical cystectomy for transitional cell carcinoma of the bladder are not yet well-defined. We reviewed our population of patients who underwent radical cystectomy to identify prognostic factors and clinical outcomes associated with upper tract recurrence. Materials and Methods: From our prospective database of 1,359 patients who underwent radical cystectomy we identified 1,069 patients treated for transitional cell carcinoma of the bladder between January 1985 and December 2001. Univariate analysis was completed to determine factors predictive of upper tract recurrence. Results: A total of 853 men and 216 women were followed for a median of 10.3 years (maximum 18.5). There were 27 (2.5%) upper tract recurrences diagnosed at a median of 3.3 years (range 0.4 to 9.3). Only urethral tumor involvement was predictive of upper tract recurrence. In men superficial transitional cell carcinoma of the prostatic urethra was associated with an increased risk of upper tract recurrence compared with prostatic stromal invasion or absence of prostatic transitional cell carcinoma (p < 0.01). In women urethral transitional cell carcinoma was associated with an increased risk of upper tract recurrence (p = 0.01). Despite routine surveillance 78% of upper tract recurrence was detected after development of symptoms. Median survival following upper tract recurrence was 1.7 years (range 0.2 to 8.8). Detection of asymptomatic upper tract recurrence via surveillance did not predict lower nephroureterectomy tumor stage, absence of lymph node metastases or improved survival. Conclusions: Patients with bladder cancer are at lifelong risk for late oncological recurrence in the upper tract urothelium. Patients with evidence of tumor involvement within the urethra are at highest risk. Surveillance regimens frequently fail to detect tumors before symptoms develop. However, radical nephroureterectomy can provide prolonged survival.
