3 Key Takeaways
Plain English Summary- 01Core Finding
Genome-wide methylation profiling reveals HGIN as an early epigenetic reprogramming stage.
- 02Study Evidence
Tested in a observational cohort study at the real-world cohort stage.
- 03Practical Meaning
Observational cohort findings reveal real-world links, though lifestyle or unmeasured factors cannot be fully ruled out without an RCT.
What This Means for You
Guided by these findings, we develop an 11-gene cfDNA methylation panel that shows robust discrimination of early-stage ESCC across three retrospective case-control sets and an independent screening-derived case-control set. Together, these results demonstrate that our cfDNA methylation panel has promising utility for early ESCC detection.
The Discovery
Early detection of esophageal squamous cell carcinoma (ESCC) is hindered by a lack of noninvasive biomarkers for precancerous lesions. Here, we report a circulating cell-free DNA (cfDNA) methylation approach for early esophageal neoplasia detection. In prospective community screening, the assay achieved standardized sensitivity at 79% specificity for the clinically actionable endpoint of high-grade intraepithelial neoplasia (HGIN) or ESCC, with stage-specific sensitivities of 76% for HGIN and 86% for ESCC. Genome-wide methylation profiling reveals HGIN as an early epigenetic reprogramming stage. Integrative spatial and single-cell RNA sequencing reveals pronounced remodeling of the endothelial (blood-vessel lining)-proximal epithelial cell population, whose methylation signatures are detected in cfDNA.
