A New Blood-Based Epigenetic Diagnostic Biomarker Test (EpiSwitch^®® NST) with High Sensitivity and Positive Predictive Value for Colorectal Cancer and Precancerous Polyps.

ABSTRACT:

Background/objectives

Colorectal cancer (CRC) arises from the epithelial lining of the colon or rectum, often following a progression from benign adenomatous polyps to malignant carcinoma. Screening modalities such as colonoscopy, faecal immunochemical tests (FIT), and FIT-DNA are critical for early detection and prevention, but non-invasive methods lack sensitivity to polyps and early CRC. Chromosome conformations (CCs) are potent epigenetic regulators of gene expression. We have previously developed an epigenetic assay, EpiSwitch^®®, that employs an algorithmic-based CCs analysis. Using EpiSwitch^®® technology, we have shown the presence of cancer-specific CCs in peripheral blood mononuclear cells (PBMCs) and primary tumours of patients with melanoma and prost
