A squamous epithelial gene interaction perturbation network index for risk stratification in esophageal squamous cell carcinoma.
Article in Journal of Cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Esophageal squamous cell carcinoma (ESCC) exhibits substantial molecular heterogeneity and unfavorable clinical outcomes. Current transcriptomic advances are shifting the focus from static gene expression profiles to the dynamic architecture of gene interaction networks. However, gene interaction perturbation signatures specific to ESCC remain poorly understood. This study aimed to develop a network-informed prognostic index derived from malignant epithelial cell signatures. In-house single-cell RNA sequencing data from 15 ESCC samples from the First Affiliated Hospital of Zhengzhou University were analyzed to identify dysregulated genes in malignant squamous epithelial cells. Then, a gene interaction perturbation network index (GIPNI) was constructed by systematically evaluating 75 combinations of machine-learning methods and validated across 3 independent cohorts. Associations between the GIPNI and genomic alterations, immune-related characteristics, and therapeutic response were also evaluated. Results showed ESCCs with high-GIPNI scores were associated with advanced clinicopathological features and overactivated mitotic cell cycle and epithelial cell differentiation pathways. Immune profiling suggested that low-GIPNI tumors had a more immune-infiltrated microenvironment. Notably, high-GIPNI ESCCs were associated with higher sensitivity to some common chemotherapeutic agents. Overall, the GIPNI provides a network-informed and malignant squamous cell-oriented framework for prognostic assessment in ESCC. This integrative approach may facilitate risk stratification and provide insights into individualized therapeutic strategies.
