OBJECTIVE

• To investigate the potential prognostic significance of the neutrophil–lymphocyte ratio (NLR) in a large European cohort of patients with upper urinary tract urothelial cell carcinoma (UUT-UCC).

PATIENTS AND METHODS

• We retrospectively evaluated data from 202 consecutive patients with non-metastatic upper urinary tract urothelial cell carcinoma (UUT-UCC), who underwent surgery between 1990 and 2012 at a single tertiary academic centre.

• Patients’ cancer-specific survival (CSS) and overall survival (OS) were assessed using the Kaplan–Meier method.

• To evaluate the independent prognostic significance of the NLR, multivariate proportional Cox regression models were applied for both endpoints.

RESULTS

• A higher NLR was significantly associated with shorter CSS (P = 0.002, log-rank test), as well as with shorter OS (P < 0.001, log-rank test).

• Multivariate analysis identified a high NLR as an independent prognostic factor for patients’ CSS (hazard ratio 2.72, 95% CI 1.25–5.93, P = 0.012), and OS (hazard ratio 2.48, 95% CI 1.31–4.70, P = 0.005).

CONCLUSIONS

• In the present cohort, patients with a high preoperative NLR had higher cancer-specific and overall mortality after radical surgery for UUT-UCC, compared with those with a low preoperative NLR.

• This easily identifiable laboratory measure should be considered as an additional prognostic factor in UUT-UCC in future.
