Efficacy of cisplatin-based neoadjuvant chemotherapy and risk factors for residual extravesical disease in muscle-invasive bladder cancer: insights from a nationwide cohort.
Article in International journal of clinical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundCisplatin-based neoadjuvant chemotherapy (NAC) improves survival in muscle-invasive bladder cancer (MIBC) as long as disease progression does not occur during treatment. However, predictors of NAC sensitivity remain elusive in clinical practice. This study evaluated the efficacy of NAC followed by radical cystectomy (NAC-RC) in cStage II-IIIA MIBC and identified the risk factors associated with residual extravesical disease.
methodsClinical data from 1474 patients who underwent radical cystectomy for cStage II-IIIA urothelial carcinoma were collected from 36 institutions of the Japanese Urological Oncology Group. Overall survival (OS) and non-urinary tract recurrence-free survival (NUT-RFS) were compared between the NAC-RC and upfront RC groups using the Kaplan-Meier method adjusted by inverse probability of treatment weighting. Logistic regression was used to identify independent risk factors for RED.
resultsPathological complete response (pT0N0) was achieved in 33.1 and 20.2% of cStage II and IIIA patients in the NAC-RC group, respectively, compared with 16.3 and 4.5% in the RC group. NAC significantly improved the OS and NUT-RFS in the IPTW-adjusted cohort. BCG-unresponsiveness, low serum albumin levels, and a high neutrophil-to-lymphocyte ratio were independent predictors of RED in the NAC-RC cohort. Squamous differentiation was associated with worse prognosis but a favorable response to NAC in some tumors.
conclusionsCisplatin-based NAC improves outcomes in patients with cStage II-IIIA MIBC, including some tumors with squamous differentiation; however, its benefits may be limited in BCG-unresponsive cases. Given the biological heterogeneity of urothelial cancer, individualized treatment planning that integrates biological features and treatment history is needed for patients with MIBC.
