<abstract xmlns="http://www.w3.org/1999/xhtml"> Introduction: The inflammatory response surrounding the tumour has a major importance in the oncologic outcome of bladder cancers. One marker proved to be useful and accessible is NLR (neutrophil-to-lymphocyte ratio). The objective of the study was the analysis of NLR as a prognostic factor for recurrence and progression in pT1a and pT1b bladder cancers. Material and Methods: Retrospective study, with 44 T1a/T1b bladder cancer patients. Each patient underwent transurethral resection. NLR was considered altered if higher than 3, average follow-up period was of 18 months.Results: The mean age of the patients included was 73 years (IQR 64 - 77). Most of the patients had NLR&lt;3 (30 patients). In total 29/44 (65.9 %) patients presented recurrence and 15/44 (34.1 %) patients were identified with T2 or higher stage progression during the follow-up period (average 18 months).We found no statistically significant association between NLR>3 and other clinic and pathologic factors. Progression-free survival (PFS) Kaplan-Meier analysis showed a lower PFS in the NLR>3 group, with a p=0.001 value. A total of 64.3% of patients had shown progression in the NLR>3 group and 20% in the NLR&lt;3 group. Mean NLR was 2.67 (IQR 1.88-3.5); 2.50 (IQR 1.89-2.87) in patients that did not present any progression during the follow-up and 3.20 (IQR 1.73-5.80) in those with progression (p=0.09), ROC 0.655. Mean NLR was 2.14 (IQR 1.61-2.77) in patients that did not experience a recurrence during the follow-up and 2.76 (IQR 2.1-4.31) in those with recurrence, ROC 0.671 (p=0.06). Multivariable Cox regression analyses showed that stage T1b and NLR represent independent prognostic factors for PFS.Conclusion: High Neutrophil-to-Lymphocyte ratio retained a statistically significant value, as an independent prognostic factor for bad prognosis of T1 bladder tumors. NLR represents a biomarker that could support a clinical decision making in case of high-risk on-muscle invasive bladder cancer.</abstract>
