A liquid biopsy-based multi-methylation marker panel for minimally invasive gastric cancer screening.

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
backgroundGastric cancer (GC) is the fifth most prevalent cancer and the fifth leading cause of cancer-related mortality worldwide. The current gold standard for clinical diagnosis is gastroscopy, which, despite its high sensitivity and specificity, is limited by its invasive nature and high cost, making it unsuitable for large-scale screening. Furthermore, the diagnostic process lacks biomarkers that offer both high sensitivity and specificity. A screening model incorporating five methylation-based biomarkers (ELMO1, FGF12, NPY, SEPTIN9, ZNF671) was developed. Using these methylation profiles, GC risk prediction models were constructed employing Random Forest.
resultsIn the training cohort of 605 subjects (259 patients with gastric cancer, 346 controls), the model demonstrated an area under the curve (AUC) of 0.9585, accuracy of 87.93%, sensitivity of 81.85%, and specificity of 92.49%. In an independent validation cohort of 152 subjects (73 patients with gastric cancer, 79 controls), the model achieved an AUC of 0.8868, accuracy of 81.58%, sensitivity of 82.19%, and specificity of 81.01%. The model showed strong screening capability across various pathological stages (0 + IA + IB, IIA + IIB, IIIA + IIIB + IIIC, IV), with AUCs of 0.8210, 0.9149, 0.9357, and 0.9383, respectively. Validation results were consistent with those from the training cohort, indicating significant potential for early-stage detection.
conclusionsThis study establishes a minimally invasive, peripheral blood DNA methylation-based detection method for GC screening. The model demonstrates robustness, high sensitivity, and specificity, offering an effective strategy for population-level screening. The primary limitations of this study include the relatively small size of the validation cohort and a significant imbalance in TNM stage distribution. Additionally, there is a potential limitation in accurately discriminating gastric cancer risk within high-risk precancerous populations based solely on the current model. It is necessary to formulate a larger-scale prospective verification plan in the future.
