However, the majority of patients do not benefit from this treatment. Hence, finding prognostic and predictive biomarkers may improve therapeutic decision-making. The aim of this study was to analyze the prognostic and predictive significance of liquid biomarkers (NLR, CRP, PLR, and LDH) in mUC patients treated with ICI.We collected articles from PubMed, Cochrane, and Embase databases with primary outcomes of overall survival (OS), progression-free survival (PFS) and objective response rate (ORR).We compiled data from a total of 6,673 ICI-treated patients with locally advanced or mUC from 31 articles. Pooled univariate analysis demonstrated that high pre-treatment NLR is significantly associated with worse OS (HR: 2.19; $95\%$ CI: 1.80-2.68) and PFS (HR: 1.90; $95\%$ CI: 1.57-2.31). Similarly, elevated CRP levels were associated with worse OS (HR: 1.75; $95\%$ CI: 1.37-2.24) and PFS (HR: 1.58; $95\%$ CI: 1.26-1.99).Elevated pre-treatment NLR, CRP, PLR, and LDH are significantly associated with worse OS and PFS in ICI-treated urothelial carcinoma patients, suggesting that they have potential prognostic and predictive value in treatment decisions.In this systematic review and meta-analysis we summarized the existing data on inflammatory laboratory biomarkers and their potential impact on immunotherapy outcomes in urothelial cancers.https://www.crd.york.ac.uk/prospero/, identifier CRD42022291449.}, subtyp = {Review Article}, keywords = {Humans / Immune Checkpoint Inhibitors: therapeutic use / Biomarkers, Tumor: blood / Prognosis / Urologic Neoplasms: drug therapy / Urologic Neoplasms: mortality / Urologic Neoplasms: immunology / Urologic Neoplasms: diagnosis / Urologic Neoplasms: blood / Carcinoma, Transitional Cell: drug therapy / Carcinoma, Transitional Cell: blood / Carcinoma, Transitional Cell: mortality / Carcinoma, Transitional Cell: immunology / Urinary Bladder Neoplasms: drug therapy / Urinary Bladder Neoplasms: blood / Urinary Bladder Neoplasms: mortality / Urinary Bladder Neoplasms: immunology / Predictive Value of Tests / CRP (Other) / NLR (Other) / PLR (Other) / bladder cancer (Other) / immune checkpoint inhibitor (Other) / urothelial carcinoma (Other) / Immune Checkpoint Inhibitors (NLM Chemicals) / Biomarkers, Tumor (NLM Chemicals)}, cin = {ED01}, ddc = {610}, cid = {I:(DE-He78)ED01-20160331}, pnm = {899 - ohne Topic (POF4-899)}, pid = {G:(DE-HGF)POF4-899}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:40165971}, pmc = {pmc:PMC11955586}, doi = {10.3389/fimmu.2025.1554048}, url = {https://inrepo02.dkfz.de/record/300213}, }
