DNA methylation markers for sensitive detection of circulating tumor DNA in patients with gastroesophageal cancers.
Article in ESMO gastrointestinal oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Background: Patients with gastric and gastroesophageal junction adenocarcinomas (G-GEJ ACs) face poor outcomes. Thus sensitive biomarkers for improved clinical management are highly warranted. Detection of circulating tumor DNA (ctDNA) using DNA methylation biomarkers is a highly sensitive approach for cancer detection and management. Here, we explored the potential of a tumor-agnostic test targeting DNA methylation to detect ctDNA in patients with resectable and advanced G-GEJ ACs. Material and methods: A tumor-agnostic digital PCR test-TriMeth-targeting the gastrointestinal cancer-specific methylated genes Results: Methylated tumor DNA was detected by TriMeth in all of the surgical tumor specimens (29/29, 100%). Furthermore, TriMeth detected ctDNA in plasma from 31/52 (60%) patients with G-GEJ AC, including in 13/17 (76%) advanced cases, and 18/35 (51%) resectable cases. ctDNA was not detected in healthy controls (0/50, 0%). Conclusions: This study demonstrates that TriMeth may hold potential as a biomarker for identifying ctDNA in patients with G-GEJ ACs. The study sets the scene for ongoing larger clinical studies investigating the performance of TriMeth in different clinical settings.
