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 (more than 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 followup for survivors was 2.6 years after 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 or less and more than 3 years after radical cystectomy. RESULTS: A total of 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 those with late recurrence 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). Cancer specific survival in early recurring cases was significantly worse than in late recurring cases 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. |
