Abstract: The present disclosure provides, among other things, methods for colorectal cancer detection (e.g., screening) and compositions related thereto. In various embodiments, the present disclosure provides methods for colorectal cancer screening that include analysis of methylation status of one or more methylation biomarkers, and compositions related thereto. In various embodiments, the present disclosure provides methods for colorectal cancer detection (e.g., screening) that include detecting (e.g., screening) methylation status of one or more methylation biomarkers in cfDNA, e.g., in ctDNA. In various embodiments, the present disclosure provides methods for colorectal cancer screening that include detecting (e.g., screening) methylation status of one or more methylation biomarkers in cfDNA, e.g., in ctDNA, using MSRE-qPCR.

Abstract: The present disclosure provides for, among other things, methods and systems for detecting, diagnosing, predicting, monitoring, screening for, staging, and/or providing survival prognosis for advanced adenoma and/or colorectal cancer using DNA methylation markers. For example, described herein are DNA methylation markers that enable categorization and prognosis evaluation of advanced adenoma (AA) and/or colorectal cancer (CRC) patients with high accuracy from human biospecimens.

Abstract: The present disclosure provides systems, methods, and apparatus for preparing biological samples (e.g., plasma) for sequencing (e.g., DNA sequencing, e.g., third generation sequencing). Moreover, the present disclosure provides various systems, methods, and apparatus that employ this sample preparation technology in the identification of biomarkers for detection of a disease or condition. For example, in certain embodiments, the biological sample preparation method includes capturing fragments of cell free DNA (cfDNA) with capture probes, converting the captured DNA fragments into circular DNA, and amplifying the circular DNA by performing rolling circle amplification (RCA). In particular, it is presently found that by performing this sample preparation method, it is possible to more successfully distinguish true alterations (e.g., aberrant methylation status and/or genomic mutations) from technical/sequencing artifacts.
