Purpose The aim of this retrospective study was to evaluate the efficacy of adjuvant cisplatin-based chemotherapy in patients with locally advanced upper tract urothelial carcinoma (UTUC), administered following radical nephroureterectomy. Materials and Methods Patients with UTUC, arising from renal pelvis or ureter, staged pT3/T4 or N+ were treated with adjuvant chemotherapy following surgery. The chemotherapy consisted of gemcitabine 1,000 mg/m2 on days 1 and 8, cisplatin 70 mg/m2 on day 1. Treatment was repeated every 3 weeks for up to 4 cycles. Endpoints included disease-free survival (DFS), metastasis-free survival (MFS), and safety. Results Among 89 eligible patients, 85 (95.5%) completed at least 3 cycles of adjuvant chemotherapy. Chemotherapy was well tolerated, the main toxicities being mild-to-moderate gastrointestinal toxic effects and pruritus. With a median follow-up of 37 months, median DFS was 30 months (95% confidence interval, 22 to 39), and the median MFS was not reached. The 3-year DFS and MFS were 44% and 56%, respectively. Multivariate analyses revealed that the main factor associated with DFS and MFS was the lymph node involvement, whereas age, T category, grade, or the primary site of UTUC were not significantly associated with DFS or MFS. Conclusion Adjuvant cisplatin-based chemotherapy after radical surgery of pT3/T4 or N+ UTUC was feasible and may demonstrate benefits in DFS and MFS. Whether novel agents added to the chemotherapy regimen, as a concurrent combination or maintenance, impacts on survival or reduces the development of metastases remains to be studied.
