Abstrakt: Background: Recurrence develops in 50% of operated bladder cancer patients. It is important to detect recurrence in advance, and there is no prognostic reliable biomarker for bladder cancer.
Objective: The aim of this study is to show that changes in hematological parameters before radiological imaging can predict recurrence.
Methods: We performed a retrospective cohort study of patients undergoing radical cystectomy for urothelial carcinoma of the bladder identified using our institutional database (2010-2022). Disease-free survival (DFS) was evaluated as relapse or death due to any cause. Kaplan-Meier analysis was used for DFS according to the follow-up period. DFS was calculated in two groups neutrophil-lymphocyte ratio (NLR) < 3 and NLR ≥ 3. Log-rank test was used for comparison between groups and p < 0.05 was considered statistically significant.
Results: In the study, 91 patients were examined. The median age was 61.0 (34-79). 57.1% of the patients were T (1-2) and 42.9% were T (3-4). The lymph node (LN) was negative in 78% and positive in 22%. Median follow-up time and DFS were 53.4 months and 54%, respectively. The median NLR was 2.8 (0.8-8.7). 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-ups; 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).
Conclusion: The change in the NLR before radiological recurrence in bladder cancer is significant in predicting recurrence. Prospective and multi-center research is needed to confirm our findings.
