Methylation status and long‐fragment cell‐free DNA are prognostic biomarkers for gastric cancer

28 Feb 2021

Abstract excerpt

BACKGROUND: Circulating tumor DNA (ctDNA) detected before surgery disappears after complete surgical resection of the cancer. Residual ctDNA indicates minimal residual disease (MRD), which is a cause of recurrence. The presence of long-fragment circulating cell-free DNA (cfDNA) or methylated cfDNA also implies the presence of cancer. In this study, we evaluated the prognostic value of cfDNA methylation and...
