DNA methylation analysis of secreted frizzled-related protein 2 gene for the early detection of colorectal cancer in fecal DNA

The early detection of colorectal cancer (CRC) with high sensitivity screening is essential for the reduction of cancer-specific mortality. Abnormally methylated genes that are responsible for the pathogenesis of cancers can be used as biomarkers for the detection of CRC. The methylation status of the secreted frizzled-related protein 2 (SFRP2) gene was evaluated for their use as a marker in the noninvasive detection of CRC
