Core Tip

Core Tip: This prospective study evaluated the detection of syndecan-2 (SDC2) methylation in preoperative and postoperative stool DNA samples of colorectal cancer (CRC) patients. The study demonstrated that the SDC2 methylation test showed high sensitivity (88.6%) for detecting CRC before surgery, indicating its potential as a non-invasive diagnostic tool. Postoperatively, the detection rate decreased to 19.7%, suggesting the normalization of SDC2 methylation after surgical resection. The study highlights the diagnostic value of SDC2 methylation in preoperative and postoperative stool samples, supporting its role as a non-invasive screening tool for CRC.
