Disparities in utilization of novel cancer therapies in advanced stage III and IV melanoma and variance in outcomes.
Article in Immunotherapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionSignificant gains in advanced melanoma have been made through immunotherapy trials. Factors influencing equitable access and survival impact of these novel therapies are not well-defined.
methodRetrospective analysis using National Cancer Database of patients with advanced stage III and IV melanoma from 2004 to 2021. Multivariable logistic regression was used to study the use of immunotherapy and Cox proportional hazard regression to evaluate overall survival (OS).
results47,427 patients with increasing utilization of immunotherapy from 13.78% in 2004 to 65.88% by 2021. Inequitable adoption were impacted by age, sex, socioeconomic status/affordability, insurance types and residential educational/income level. Receiving immunotherapy was associated with a 44% improvement in OS (HR 0.56, 95% CI 0.54-0.57) and receiving a clinical trial-based therapy was associated with a 37% improvement (HR 0.63, 95% CI 0.53-0.75). Among patients who received immunotherapy or clinical trial-base therapy, there was 40% worse survival in non-Hispanic Black patients (HR 1.40, 95% CI 1.16-1.69) compared to non-Hispanic Whites.
conclusionThere are disparities in utilization of immunotherapy that is influenced by socioeconomic status. Race and ethnicity had a significant influence in differential impact on survival outcomes of immunotherapies highlighting the importance of increasing underrepresented population participation in trials that lead to novel therapies.
