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

backgroundHereditary diffuse gastric cancer (HDGC), caused by pathogenic variants (PVs) in CDH1, typically presents as early-stage mucosal lesions composed of non-proliferative signet ring cells (SRCs). While loss of E-cadherin initiates tumorigenesis, the somatic genetic alterations driving progression to advanced disease remain poorly understood.

objectiveOur goal was to identify morphological and genetic changes associated with HDGC progression.

designWe performed whole exome sequencing on 38 gastric tumors from 26 HDGC patients, spanning early to advanced stages, and compared genetic alterations across tumor stages.

resultsEarly-stage HDGC lesions exhibited minimal somatic alterations, with low tumor mutational burden (TMB) and few cancer-related mutations. In contrast, advanced tumors showed a significant increase in TMB and frequent somatic mutations in CDH1, TP53, and genes involved in TGF-β signaling, cell adhesion, and actomyosin contractility (e.g., SMAD4, FAT4, RHOA). Copy number variations (CNVs) were also more prevalent in advanced tumors, including recurrent loss of 3p and 17p and amplification of oncogenes MYC and MET. CNV profiles varied between tumor regions, indicating intratumoral heterogeneity and potential clonal evolution.

conclusionHDGC progression is marked by a stepwise accumulation of somatic mutations and chromosomal alterations. While early lesions remain genetically quiet, advanced tumors exhibit complex genetic landscapes, including CDH1 inactivation, oncogenic mutations, and CNVs. These findings highlight key molecular events in HDGC progression and may inform future strategies for early detection and targeted intervention.
