Abstract

Objectives

To analyze the potential survival benefit of perioperative chemotherapy (CHT) in patients treated with nephroureterectomy (NU) for non-metastatic locally advanced upper tract urothelial carcinoma.

Methods

Within the Surveillance, Epidemiology, and End Results database (2004–2014), we identified 1286 patients with T3 or T4, N 0–3 M0 UTUC. Kaplan–Meier plots, as well as multivariable Cox regression models (MCRMs) relying on inverse probability after treatment weighting (IPTW) and landmark analyses, were used to test the effect of CHT vs no CHT on overall mortality (OM) in the overall population (n =1286), as well as after stratification according to lymph node invasion (LNI).

Results

Overall, 37.4% patients received CHT. The CHT rate was higher with LNI (62.2% vs 35.2%, p < 0.001). In MCRMs, testing for OM in the overall population, CHT was associated with lower rates of OM (HR 0.71, CI 0.58–0.87; p = 0.001). Similarly, in MCRMs testing for OM in patients with LNI, CHT achieved independent predictor status for lower OM (HR 0.61, CI 0.48–0.78; p < 0.001). Conversely, in MCRMs testing for OM in patients without LNI, no CHT effect was recorded (HR 0.72, CI 0.52–1.01; p = 0.05). All results were confirmed after IPTW adjustment and in landmark analyses.

Conclusions

Our results represent a contemporary North American report indicating lower OM after CHT for patients with locally advanced non-metastatic upper tract urothelial carcinoma, specifically in patients with T3–T4, N1–N3, M0 disease. Validation of the current and of the previous study is required within a randomized prospective design.
