1 · What the graph read from it

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.

2 · The registry

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

introductionPeritoneal metastasis is a prevalent form of gastric cancer spread, often resulting in poor outcomes. Due to the lack of clinical recommendation for surgery, current omics studies are limited to analyzing suspending malignant cells in ascites using external controls, rather than examining peritoneal metastatic nodules alongside their paired primary tumors.

objectivesThis study aims to elucidate the genomic landscape of gastric cancer peritoneal metastasis and identify key genetic drivers by comparing peritoneal dissemination lesions and their corresponding primary samples.

methodsWhole-exome sequencing of 30 samples from 15 gastric cancer patients with peritoneal metastasis was conducted. We compared mutational and copy number variations, explored actionable targets and biomarkers, and contextualized our findings with the TCGA cohort.

resultsWe identified distinct mutation patterns in gastric cancer with peritoneal metastasis, including increased mutation frequency in the cadherin superfamily and Fanconi anemia pathway. Peritoneal metastasis and primary lesions frequently harbored both parental clones and specific subclones. Well-known driver mutations (e.g., TP53, FAT1, CDH1, ARID1A) occurred early in gastric cancer tumorigenesis, while peritoneal metastasis-specific mutations (e.g., FADS6, NDUFS7, DUSP4) and mutational signatures were linked to adverse outcomes. DEK amplification was significantly higher in peritoneal metastasis lesions (46.7 %) versus primary tumors (13.3 %), with DEK expression levels closely associated with gastric cancer stemness signatures, validated through in vitro and in vivo studies.

conclusionOur study elucidates clonal evolution in gastric cancer peritoneal metastasis, identifies mutational drivers, and highlights potential therapeutic targets. These findings provide valuable insights for developing precise treatment strategies for gastric cancer patients with peritoneal metastasis.
