DNA Methylation in Lung Cancer: Predictive Biomarkers for Effective Immunotherapy.
Review in International journal of general medicine, 2025. 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
Lung cancer remains a leading cause of cancer-related mortality worldwide, and immunotherapy has emerged as a promising treatment modality. However, its efficacy is limited to a subset of patients, necessitating predictive biomarkers for personalized treatment strategies. DNA methylation (DNAm) is increasingly recognized as a crucial regulators of gene expression and immune responses in the tumor microenvironment. This review focuses on DNAm as a key epigenetic biomarker for predicting and enhancing immunotherapy efficacy in lung cancer. We highlight DNAm changes in key immune-related genes and their association with tumor phenotype, immune cell infiltration, and response to immune checkpoint inhibitors (ICIs). The review also evaluates established and emerging genomic and non-genomic biomarkers, including tumor mutational burden (TMB), microsatellite instability (MSI), PD-L1 expression, tumor-infiltrating lymphocytes (TILs), and immunosuppressive cytokines in case of lung cancer immunotherapy. Furthermore, the potential for integrated epigenetic signatures and minimally invasive diagnostic approaches, such as liquid biopsies, is discussed. Finally, we address the challenges and future directions for translating epigenetic biomarkers into clinical practice to improve immunotherapy outcomes and reduce immune-related adverse events.
