Racial and ethnic disparities in esophageal cancer survival are greatest at curable stages: a population-based study.
Article in Cancer causes & control : CCC, 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
backgroundRacial and ethnic disparities in esophageal cancer outcomes are documented, but whether they differ by stage at diagnosis is unclear. Using population-based data from Florida, a diverse, Medicaid non-expansion state, we conducted a stage-stratified analysis of racial/ethnic differences in survival and treatment receipt.
methodsWe analyzed 21,814 esophageal cancer cases from the Florida Cancer Data System (2005-2021). Using cause-specific Cox models, we estimated adjusted hazard ratios (aHRs) for cancer-specific mortality overall and by stage, adjusting for demographics, tumor characteristics, treatment, smoking, and socioeconomic factors. Multivariable logistic regression assessed racial/ethnic differences in receipt of surgery, chemotherapy, and radiation.
resultsPatients were 81.0% non-Hispanic (NH) White, 8.0% NH Black, and 10.0% Hispanic. NH Black patients had higher overall mortality than NH White patients (aHR: 1.08; 95% CI 1.02-1.15). Stage-stratified models showed elevated mortality among NH Black patients at localized (aHR: 1.24; 95% CI 1.05-1.45) and regional stages (aHR: 1.19; 95% CI 1.07-1.35) compared with NH White patients, but lower mortality at distant stage (aHR: 0.88; 95% CI 0.80-0.98). NH Black patients had lower odds of surgery (aOR: 0.51; 95% CI 0.43-0.61) and chemotherapy (aOR: 0.79; 95% CI 0.70-0.90) compared with NH White patients; radiation receipt did not differ.
conclusionSurvival disparities were most pronounced at curable stages, indicating inequities in post-diagnosis management. Lower treatment receipt and persistent survival differences after clinical adjustment suggest that structural and systemic factors contribute. These findings highlight a critical target for cancer control and underscore the need for system-level reforms to ensure equitable, stage-appropriate care.
