667-A Pan-Cancer Resource of 1,294 Plasma cfDNA Methylomes

This research presents a comprehensive pan-cancer resource consisting of 1,294 plasma cell-free DNA samples to improve noninvasive tumor detection. By developing a standardized computational workflow, the authors integrated DNA methylation and fragmentomic data across eleven distinct cancer types. The study identified thousands of cancer-associated markers while effectively mitigating technical biases and biological confounders like age and sex. Their findings demonstrate that combining methylation with fragmentation features—such as 5′ end motifs and fragment ratios—significantly enhances the accuracy of cancer classification. This large-scale compendium serves as a foundational dataset for advancing liquid biopsy technologies and monitoring disease evolution. Success was further confirmed through independent validation, proving the robustness of these integrated biomarkers for clinical use.References: Zeng Y, Abelman D D, Singhawansa A, et al.
