PD52-09 LATE RECURRENCES FOLLOWING RADICAL CYSTECTOMY HAVE DISTINCT PROGNOSTIC AND MANAGEMENT CONSIDERATIONS

PURPOSE: Disease recurrence after radical cystectomy generally occurs within 2 years and has a poor prognosis. Less well defined are the outcomes in patients who experience a late recurrence (>3 years after radical cystectomy). We report our institutional experience with late recurrences and describe the relationships between time to recurrence, management strategies, and survival. MATERIALS AND METHODS: The study cohort comprised 2,315 patients who underwent radical cystectomy for urothelial carcinoma at our center between 2000 and 2014, of whom 617 had a recurrence. Median follow-up for survivors was 2.6 years post-recurrence (IQR 0.95-4.5). For the study, we considered disease recurrence as recurrences outside the urinary tract. We compared baseline characteristics and post-recurrence management between those with recurrence 3 years after radical cystectomy. RESULTS: 58 patients with late recurrence had significantly lower consensus T stage and lower frequency of nodal involvement. The average 1-year bladder cancer death rate from the time of recurrence declined from 66% to 50% to 33% for patients with recurrence times of 6 months, 2 years, and 5 years after radical cystectomy, respectively. For patients who survived at least 1 year after recurrence, the estimated survival at 5 years after recurrence was 45% for late recurring patients and 21% for patients who had an early recurrence. Local consolidative therapy (metastasectomy or radiation) was more common in patients with late recurrence (19% vs. 3.6%, p < 0.0001), and cancer-specific survival in early-recurring patients was significantly worse than in late-recurring patients in the subset receiving local consolidation (p = 0.02). CONCLUSIONS: The prolonged lifespan of patients experiencing a late recurrence after radical cystectomy can be leveraged to individualize management. There is strong rationale for investigating the role of metastasectomy in the management of late recurrences.
