Background Increased neutrophil-to-lymphocyte ratio (NLR), an index of systemic inflammation, is associated with poor outcome for various types of cancers. We assessed the role on outcome prediction of NLR at baseline and persistent during first-line chemotherapy in patients with advanced urothelial cancer. Methods We retrospectively reviewed 292 patients with unresectable or metastatic urothelial cancer treated with first-line chemotherapy between January 2003 and December 2012. The cutoff values of NLR (>3 vs. 12 g/dL), pretherapy NLR (>3 vs. 3 vs. ≤3). Results Patients with pre- and follow-up NLR of >3 had a median progression-free survival of 3.2 months and a median overall survival of 5.7 months. In multivariate analysis, visceral metastases, pretherapy hemoglobin, and follow-up NLR were significant predictors of progression-free survival [hazard ratio (HR) 1.75, P = 0.0001; HR 1.57, P = 0.0015; HR 2.77, P
