Years of Life Lost in Patients with Muscle-Invasive and Metastatic Bladder Cancer.
Article in Annals of surgical oncology, 2026. 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
backgroundMuscle-invasive and metastatic urothelial carcinoma of urinary bladder (UCUB) is associated with poor overall survival. However, individual years of life lost (YLL) according to detailed patient and disease characteristics have never been quantified. PATIENTS AND
methodsWithin the Surveillance, Epidemiology, and End Results (SEER) database (2004-2021), muscle-invasive organ-confined (OC, T2N0M0), non-organ-confined (NOC, T3-4 and/or N1-3 M0), and metastatic (anyT, anyN, M1) UCUB patients aged 40-75 years were included. Relying on Social Security Administration (SSA) life tables, a 1:1 age, sex, and year of diagnosis matched control (Monte Carlo simulation) was simulated for each patient. Kaplan-Meier method was used to calculate average YLL truncated at the age of 75 years between SEER cases and SSA simulated controls.
resultsA total of 30,519 patients were included: 14,754 (48.3%) OC, 10,330 (33.8%) NOC, and 5435 (17.8%) metastatic. Compared with simulated population controls, average YLL was 3.7, 6.0, and 9.1 years for OC, NOC, and metastatic disease, respectively. YLL was most pronounced among patients diagnosed at younger ages (40-55 years: 9.2, 14.1, and 18.0 years for OC, NOC, and metastatic, respectively), decreasing with advancing age at diagnosis. Less pronounced YLL observations were recorded in most contemporary years (2017-2021: 2.7, 4.4, and 7.9 years for OC, NOC, and metastatic, respectively) across all stages compared with earlier periods. No clinically meaningful differences in YLL were observed between sexes. (male OC: 3.6, NOC: 5.9, metastatic: 9.0; female OC: 4.1, NOC: 6.6, metastatic: 9.5).
conclusionsUCUB is associated with substantial YLL, particularly in metastatic and younger patients. However, an YLL decrease over time was observed.
