Integrative Analysis of Telomere-Related Genes Reveals Prognostic Signatures in Laryngeal Cancer.

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: Laryngeal cancer (LC) is a common malignant tumor. Telomere-related genes (T-RGs) play critical roles in cellular senescence and carcinogenesis, but their prognostic relevance in LC remains to be fully elucidated. Therefore, exploring the prognostic genes related to telomeres in LC is important. Methods: Public retrospective datasets TCGA-HNSC and T-RGs were used to identify candidate genes by intersecting differentially expressed genes with T-RGs. Key analytical approaches, including machine learning algorithms and univariate Cox regression, were applied to identify prognostic genes and construct a prognostic model. A nomogram was developed to assess the prognostic value for LC based on overall survival. Disease samples were classified into high-risk and low-risk groups, and subsequent analyses included immune infiltration, immune checkpoint expression, and related evaluations. Experimental validation of prognostic genes was performed through RT-qPCR. Results: A total of 314 candidate genes were obtained from 8961 differentially expressed genes. Four key prognostic genes (CHTF18, FANCG, NR5A1, and XRCC3) were identified. The constructed risk score model retained consistent predictive accuracy in both the training and validation datasets, with AUCs ranging from approximately 0.61 to 0.9. Enriched activated immune cells were detected in the low-risk group through immune microenvironment analysis, whereas immune suppression-related features were identified in the high-risk group, accompanied by a reduced tumor mutational burden that was detected. Finally, preliminary validation using RT-qPCR in a limited cohort of clinical samples indicated that the expression trends of three prognostic genes were elevated in LC tissues, showing concordance with the bioinformatic findings. Conclusions: This study identified four key prognostic T-RGs (CHTF18, FANCG, NR5A1, and XRCC3) and constructed a corresponding prognostic model for LC. Our analyses further suggest a potential link between telomere maintenance mechanisms and the tumor immune microenvironment, which may influence patient outcomes.
