DNA methylation of secreted frizzled-related proteins (SFRPs) can be detected in colorectal cancer (CRC) tissue, in tissue of adenomas, and in aberrant crypt foci, whereas in normal colorectal mucosa tissue, SFRP genes are unmethylated. Recently, our study group was able to demonstrate SFRP2 methylation as the most sensitive single DNA-based marker in stool for identification of CRC. The purpose of this study was to clarify whether SFRP2 methylation in fecal DNA can be found in stool of individuals with hyperplastic and adenomatous colorectal polyps.
