Upper urinary tract recurrence following radical cystectomy for bladder cancer.
OBJECTIVE
The objective of this study was to analyze the clinicopathological features of upper urinary tract recurrence following radical cystectomy for bladder cancer.


METHODS
Between 1995 and 2003, 583 patients underwent radical cystectomy and urinary diversion for bladder cancer at the authors' institution and the related hospitals. A retrospective review of patient records was carried out to evaluate characteristics of patients who underwent upper urinary tract recurrence after radical cystectomy.


RESULTS
During the observation period (median, 41.5 months), 12 (2.1%) of the 583 patients had upper urinary tract recurrence. Of the 12 patients with upper urinary tract recurrence, there were multiple tumors in eight at the initial diagnosis of bladder cancer, and eight received transurethral resections two or more times before radical cystectomy. The median time to diagnosis of an upper urinary tract cancer after radical cystectomy was 29.5 months. When upper urinary tract recurrence was detected, five patients had metastatic diseases simultaneously, and two had bilateral upper urinary tract cancers. The cancer-specific survival in patients with upper urinary tract recurrence was significantly poorer than that in those without upper urinary tract recurrence. In addition, eight of the 12 patients (66.7%) died of disease progression within 3 years after the diagnosis of upper urinary tract cancer.


CONCLUSIONS
These findings suggest that despite the low incidence of upper urinary tract recurrence following radical cystectomy, the prognosis of such patients was markedly poorer compared with that of those without upper urinary tract recurrence. Accordingly, intensive therapies should be considered when upper urinary tract recurrence is detected after radical cystectomy.
