Disease\u2010free survival (DFS) was evaluated as relapse or death due to any cause. Kaplan\u2010Meier analysis was used for DFS according to the follow\u2010up period. DFS was calculated in two groups neutrophil\u2010lymphocyte ratio (NLR)\u00a0&lt;\u00a03 and NLR\u00a0\u2265\u00a03.

The median age was 61.0 (34\u201379). 57.1% of the patients were T (1\u20132) and 42.9% were T (3\u20134). The lymph node (LN) was negative in 78% and positive in 22%. Median follow\u2010up time and DFS were 53.4 months and 54%, respectively. The median NLR was 2.8 (0.8\u20138.7). For DFS, there was a significant difference according to age, T stage, and LN status (p: 0.048, 0.019, and 0.040). There was no significant difference in the NLR in terms of DFS at the time of diagnosis (p: 0.654). In follow\u2010ups; While there was no difference in the NLR for DFS 12 months before recurrence (p: 0.231), there was a significant difference 6 months before the relapse and at the time of recurrence (p: 0.023 and 0.031).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The change in the NLR before radiological recurrence in bladder cancer is significant in predicting recurrence.
