Multi-gene DNA methylation profiles of tumor suppressor genes for prognostic prediction in gastric cancer.
Article in BMC cancer, 2026. 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
backgroundThis study aimed to identify prognostic biomarkers for gastric cancer (GC) by analyzing the methylation status of multiple tumor suppressor genes.
methodsUsing the Epi-TOP™ methylation detection system, we analyzed 51 genes in 169 matched tumor and adjacent normal tissue samples. Methylation levels were quantified as Percent Methylated Reference (PMR) in tumor (PMR-T) and normal (PMR-N) tissues; the differential methylation (PMR-D) was also calculated.
resultTumor tissues exhibited significantly higher DNA methylation levels than matched normal tissues across 51 tumor suppressor genes (all p < 0.001). Clustering analysis based on PMR-T identified four epigenetic subtypes associated with known molecular classifications (epithelial–mesenchymal transition (EMT) and microsatellite instability–high (MSI-H)) and overall survival (p = 0.030). In contrast, clustering based on PMR-N showed no significant association with molecular subtypes or survival outcomes, suggesting limited prognostic relevance. Two prognostic gene panels were constructed: one PMR-T–based panel (ALX, BMP3, CDKN2A, MINT25, PTGDR) and another PMR-D-based panel (ADCYAP1, SOCS1, SEPTIN9, CDKN2B). Both panels independently predicted overall survival in multivariate Cox regression. The PMR-D panel demonstrated stronger prognostic performance (hazard ratio (HR) = 0.329, p = 0.002), while the PMR-T panel also demonstrated significant prognostic value (HR = 0.512, p = 0.012), highlighting that tumor methylation profiles alone may provide meaningful survival predictions for patients with GC.
conclusionThis study demonstrates that tumor-specific DNA methylation changes, particularly when evaluated using multi-gene panels can enhance prognostic stratification in GC. These findings support the potential use of methylation-based biomarkers for personalized management of GC.
