MP55-05 LATE RECURRENCE FOLLOWING RADICAL CYSTECTOMY FOR UROTHELIAL CARCINOMA OF THE BLADDER

Abstract

INTRODUCTION AND OBJECTIVES: Patients who experience disease recurrence after radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB) have a very poor prognosis. Most recurrences occur during the first two years following RC. The incidence, patterns, and prognosis of late recurrences (LRs) following RC have not been well described. METHODS: We queried our prospectively maintained institutional database and identified 1953 consecutive patients who underwent RC for UCB from 1995-2010. We identified patients who experienced disease recurrence following RC and analyzed both nonurothelial tract disease recurrence and urothelial recurrence. Late recurrence was defined as a non-urothelial tract recurrence occurring three or more years following RC. RESULTS: Of 648 UCB patients who experienced non-urothelial tract disease recurrence following RC, 93 (14%) occurred greater than 3 years following RC, and 42 (6%) occurred after 5 years (range 3.01 e 12.89 years). Of these 93 LRs, 22 (24%) were local, 54 (58%) were distant, and 17 (18%) were both local and distant. Sites of metastasis in patients with LRs included 21 (23%) lung, 20 (22%) bone, 47 (51%) lymphatic, 18 (19%) liver, 20 (22%) pelvis, and 5 (5%) other. Urothelial tract recurrences were identified in 44 of 93 patients with LR, 30 upper tract and 18 urethral. After excluding 17 patients in whom the LR could be ascribed to an invasive upper tract second primary tumor, 76 LR patients were left for analysis. The stage distribution at RC for LR patients was pT0 (7%), pTa (5%), pTis (18%), pT1 (12%), pT2 (26%), pT3 (21%), and pT4 (8%). Twelve LR patients (16%) had LN-positive disease. Eleven LR patients had received pre-operative cisplatin-based chemotherapy and 8 received adjuvant chemotherapy. LR patients were more likely to have organ-confined disease at RC (62% vs. 21%, p<0.001) and concomitant CIS (78% vs. 61%, p1⁄40.02) than patients experiencing recurrence within 3 years. However, the prognosis following recurrence was similarly poor for patients experiencing LR as it was for early recurrence, although LR patients had a slightly longer time from recurrence to death (p1⁄40.002). CONCLUSIONS: Bladder cancer patients treated with RC remain at risk for disease recurrence for many years, although the majority of patients who will recur do so within the first two years. Patients who experience late recurrence have different disease characteristics than those who experience early recurrence. Continued surveillance for detection of local, distant, and urothelial recurrences following RC may be beneficial.
