5mC and 5hmC colorectal cancer cfDNA biomarker classifier
exploratoryImprove early-stage colorectal cancer detection using separate 5mC and 5hmC measurements in cell-free DNA liquid biopsy samples.
Analyzed cfDNA from treatment-naive CRC patients and healthy controls using duet evoC 6-base whole genome sequencing, then built CRC classifiers using differentially methylated regions.
2026 Communications Medicine publication reported classifier performance using 37 CRC patients and 32 healthy controls.
Models combining 5mC and 5hmC achieved AUC 0.95, outperforming modified cytosine-only models with AUC 0.66; findings support distinguishing 5mC and 5hmC to improve liquid biopsy sensitivity.
