The predictive role of tertiary lymphoid structures in the prognosis and response to immunotherapy of bladder cancer patients: a systematic review and meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe association between tertiary lymphoid structures (TLS) and clinical outcomes in bladder cancer (BCa) patients, particularly their value in predicting immunotherapy response, remains inconsistent and has not been systematically evaluated.
objectiveThis systematic review and meta-analysis aimed to: (1) evaluate the association between TLS and survival outcomes in BCa; (2) examine the relationship between TLS and clinicopathological characteristics; and (3) summarize evidence on TLS and immunotherapy response.
methodsWe systematically searched PubMed, Embase, and Web of Science from inception to February 1, 2026. Hazard ratios (HRs) with 95% confidence intervals (CIs) for overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS) were extracted and pooled. The study protocol was registered with PROSPERO (CRD420261282595).
resultsEight studies involving 1706 patients were included in the quantitative synthesis. Pooled analysis revealed that high TLS levels were significantly associated with improved OS (HR = 0.49, 95% CI: 0.33-0.74), PFS (HR = 0.51, 95% CI: 0.45-0.58), and DFS (HR = 0.42, 95% CI: 0.22-0.79). TLS showed a significant correlation only with tumor multiplicity among various clinicopathological features. Qualitative synthesis of six studies suggested that while baseline TLS had limited predictive value for immunotherapy response, therapy-induced increases in TLS number, density, and maturation were consistently associated with favorable treatment outcomes.
conclusionHigh TLS levels are associated with favorable survival outcomes in bladder cancer patients, supporting their role as a prognostic biomarker. Therapy-induced TLS dynamics, rather than baseline status alone, may be a more relevant predictive biomarker for immunotherapy efficacy. These findings warrant validation in larger, prospective studies.
