Stage-Specific Tumoral Gene Expression Profiles of Black and White Patients with Colon Cancer.

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
backgroundBlack patients with colon cancer (CC) exhibit more aggressive tumor biology and higher treatment resistance than white patients, even after adjusting for clinical and demographic factors. We investigated stage-specific transcriptional differences in tumor profiles of Black and white patients with CC. PATIENTS AND
methodsPatients with CC from The Cancer Genome Atlas Colon Adenocarcinoma database were categorized by disease stage and propensity-score matched between Black and white patients. Differential gene expression and pathway enrichment analyses were performed for each stage. Logistic regression and quadratic discriminant analysis (QDA) models were developed using consistently differentially expressed genes.
resultsOf 247 patients, 128 had localized (22% Black), 81 had regional (74% Black), and 38 had distant disease (29% Black). Differential expression analysis revealed differences in 312 genes for localized, 105 for regional, and 199 for distant stages between Black and white patients. Pathway enrichment analysis showed downregulation of the IL-17 pathway in Black patients with localized disease. In total, five genes exhibited race-specific transcriptional differences across all stages: RAMACL, POLR2J3, POLR2J2, MUC16, and PRSS21. Logistic regression and QDA model performance indicated that these genes represent racial differences [area under the receiver operating characteristic curve (AUC): 0.863 and 0.880].
conclusionsSignificant transcriptional differences exist in CC between Black and white patients changing dynamically across disease stages, and involving genes with broad functions. Key findings include IL-17 pathway downregulation in Black patients with localized disease and a five-gene signature consistent across all stages. These findings may explain aspects of racial disparities in CC, emphasizing the need for race-specific research and treatment strategies.
