The role of circadian genes in predicting immunotherapy response and survival outcomes in cancer patients.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundDysregulation of circadian rhythms is implicated in cancer, but circadian genes impact on survival outcomes and response to immunotherapy remains unclear. This study aimed to systematically investigate these relationships and establish predictive models based on circadian gene expression.
methodsWe integrated transcriptomic and clinical data from 15 published immunotherapy cohorts (n = 768) and TCGA pan-cancer datasets. Circadian risk scores stratified patients for survival analysis. Machine learning models (incorporating 9 algorithms; optimized via 10-fold cross-validation with grid search) were developed using circadian signatures to predict immunotherapy response. Functional enrichment analysis (GO, KEGG, and Reactome) was subsequently performed to identify the underlying biological pathways.
resultsWe identified 15 circadian genes significantly associated with survival (P < 0.05). The most hazardous gene was CSNK1D (HR = 1.18, 95% CI: 1.13-1.24), while KLF10 conferred strongest protection (HR = 0.93, 95% CI: 0.91-0.95). Remarkably, Kaplan-Meier survival curves revealed significant survival differences between high-risk and low-risk groups stratified by a circadian risk score. Notably, this effect was significant in PCPG (P = 0.03), LUAD (P = 0.02), and COAD (P = 0.01). Additionally, machine learning models, particularly Support Vector Machine (SVM; AUC = 0.913) and Random Forest (RF; AUC = 0.909), effectively predicted immunotherapy response. Feature importance analysis derived from these models highlighted several key circadian genes, including BHLHE40, KLF10, PER1, PER3, CSNK1D, and CSNK1E. Feature importance analysis derived from these models highlighted several key circadian genes, including BHLHE40, KLF10, PER1, PER3, CSNK1D, and CSNK1E. Enrichment analysis linked subgroup divergence to translational regulation, energy metabolism, and neurodegenerative pathways.
conclusionCore circadian genes represent promising candidate biomarkers for both cancer survival risk stratification and immunotherapy response prediction. They further enable the development of high-accuracy machine learning models to predict immunotherapy responses.
