Zusammenfassung
Purpose: DNA methylation biomarkers can be used to detect tumor-derived circulating DNA and diagnose colorectal cancer (CRC) in blood as demonstrated by the CE-marked Epi proColon for the detection of methylated-SEPT9 ( m SEPT9) in plasma. In addition to qualitative assessment of m SEPT9 for early detection, quantitative assessment of m SEPT9 could provide information to the physician following diagnosis. Materials and methods: m SEPT9 and methylated-RASSF2A were measured using quantitative-PCR on bisulfite-converted DNA from CRC patient plasma taken before and following surgery. A multi-center clinical study wa…
