Brief Summary

The goal of this exploration study is to evaluate the performance of a colorectal cancer (CRC) early screening model based on the DNA methylation technology platform. The study focuses on individuals over the age of 40 and aims to identify and verify methylation biomarkers for colorectal cancer using stool samples . The main question it aims to answer is: Can a DNA methylation-based model effectively detect colorectal cancer and adenoma in individuals over 40 using non-invasive stool samples? Participants will provide stool samples for methylation analysis. The study results will be used solely for internal product performance evaluation and optimization by the sponsor and will not be used for product registration or influence any clinical diagnosis.

Conditions

CRC (Colorectal Cancer); Adenoma Colon

Outcome Measures

Primary Outcomes (1)

• human stool gene methylation

  The core of the study is to detect the methylation levels of three genes in human stool samples. These three genes are SDC2, COL4A2, and C9orf50. The procedure includes stool sample collection, stool nucleic acid extraction, bisulfite conversion, and detection using the qMSP (quantitative Methylation-Specific PCR) method.
