Abstract

Objective: To evaluate the efficacy of adjuvant cisplatin-based chemotherapy for locally advanced upper tract urothelial cell carcinoma (UTUC) following radical nephroureterectomy with bladder cuff resection (RNU) in terms of survival and recurrence.

Materials and methods: Between January 2000 and January 2013, among 145 patients with upper tract urothelial cell carcinoma, a total of 65 patients with locally advanced UTUC (a diagnosis of pT3 or pT4 or pT1-2N1-3) underwent RNU. Of these 65 patients, 36 patients received at least three cycles of adjuvant gemcitabine plus cisplatin chemotherapy and the remaining 29 patient did not receive adjuvant chemotherapy. Clinical characteristics, bladder recurrence, distant metastasis, and cancer-specific survival were retrospectively reviewed.

Results: The mean age of the 65 patients was 60.4 (range, 37-87) years and the median follow-up period was 34 (range, 12-114) months. Patent demographics were not statistically different between the two groups. During the follow-up period, 14 patients (21.5%) experienced distant metastasis; 8 (8/36, 22.2%) patients who had undergone adjuvant chemotherapy and 6 (6/29, 20.7%) patients who did not. Bladder recurrence was noted in 17 patients (26.2%), 5 (5/36, 13.9%) of whom received adjuvant chemotherapy while the remaining 12 (12/29, 41.4%) did not. Kaplan-Meire and multivariate analysis showed that the incidence of bladder recurrence was significantly higher in patients who did not undergo adjuvant chemotherapy, and cancer specific survival was not significantly associated with adjuvant chemotherapy.

Conclusions: Adjuvant chemotherapy for locally advanced UTUC can prevent bladder recurrence, but has a minimal effect on cancer-specific survival.
