Real-world economic burden of disease recurrence in patients with muscle-invasive bladder cancer: A population-level claims-based analysis.
Observational study in Journal of managed care & specialty pharmacy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundBladder cancer is a common cancer with significant morbidity, mortality, and economic cost. Muscle-invasive bladder cancer (MIBC) is typically managed with radical cystectomy (RC). Despite its curative intent, a considerable proportion of patients experience recurrence after RC. The economic impact of recurrence among patients with surgically resected MIBC has not been described.
objectiveTo assess health care resource utilization (HCRU) and costs among patients with surgically resected MIBC in the United States, including the impact of disease recurrence.
methodsIn this retrospective, observational study, the Surveillance, Epidemiology, and End Results-Medicare database (2007-2020) was used to identify patients diagnosed with T2-T4aN0M0 or T1-T4aN1M0 MIBC who underwent RC in the United States. Index date was the date of RC. Patients were stratified by whether they experienced recurrence following surgical resection. The index date for patients with recurrence was defined as 30 days prior to recurrence, and for patients without recurrence, the index date was drawn from a distribution to match the time window between surgical resection and the index date in the recurrence cohort. Patients were followed from the index date until the end of data availability, continuous enrollment, or death. Rates of HCRU per patient per year (PPPY) and mean health care costs per patient per month (PPPM; in 2022 USD) were summarized and compared between cohorts.
resultsA total of 1,149 patients met selection criteria. Patients had a median of 2.6 years of follow-up. Demographic and clinical characteristics were generally similar between patients with (n = 503) and without recurrence (n = 602), with few exceptions. Patients with recurrence (compared with those without) were more likely to have had stage IIIA disease (47.9% vs 32.7%) and a proxy for cisplatin contraindications (54.1% vs 47.5%, both
conclusionsSurgically resected MIBC was associated with a substantial economic burden with disease recurrence experiencing higher HCRU and health care costs. These findings underscore the need for novel and effective therapies that can prevent or delay disease recurrence for patients with MIBC.
