Emergency cancer diagnosis in older adults: patterns, subgroups, and implications for health-care quality metrics.
Article in JNCI cancer spectrum, 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
backgroundCancer diagnosis originating in emergency departments (emergency presentation) contributes to poorer cancer survival and reflects aggressive disease and limited access to routine health care. This study characterized emergency presentations for a range of cancers and subclassified by whether patients were hospitalized after the emergency encounter, with the hypothesis that, compared with those hospitalized, patients not requiring hospitalization more specifically represent barriers to timely and adequate care.
methodsWe analyzed Surveillance, Epidemiology, and End Results-Medicare data for patients aged 66 years and older diagnosed with 14 cancer types (2008-2017; n = 614 885). We described emergency presentation overall and demographic and clinical characteristics across subgroups using linear regression and assessed differences in health-care utilization before the emergency presentation classification window.
resultsIn total, 234 606 (38%) patients were classified as emergency presentations, with 187 439 (80%) hospitalized. Emergency presentations were more likely than nonemergency presentations to have prediagnostic emergency care (40%, 95% confidence interval [CI] = 40% to 40%) vs 30% (95% CI = 29% to 30%) and less likely to have nonemergency care for potential cancer symptoms (61%, 95% CI = 61% to 61%, vs 67%, 95% CI = 67% to 67%), with minimal variation between inpatient and outpatient emergency presentations. Compared with inpatient emergency presentations, outpatient emergency presentations were more often younger than 70 years old (24%, 95% CI = 23% to 24%, vs 19%, 95% CI = 19% to 19%), nonmetropolitan residents (25%, 95% CI = 24% to 25%, vs 12%, 95% CI = 12% to 12%), and had localized cancer (25%, 95% CI = 25% to 26%, vs 17%, 95% CI = 17% to 17%).
conclusionsMore than one-third of older adult US cancer patients with these cancer types are diagnosed through emergency presentation, with most requiring hospitalization. Outpatient emergency presentations are more common among patients in rural areas with less advanced cancers, suggesting they may be an informative indicator of avoidable barriers to care less influenced by underlying health status.
