A Stool DNA-Based SDC2 Methylation Test for the Early Detection of Colorectal Cancer in an Asymptomatic, High-Risk Population: A Multicenter Prospective Randomized Trial.

Introduction: Noninvasive stool DNA-based methylation testing has emerged as an effective strategy for the early colorectal cancer (CRC) detection. Syndecan-2 (SDC2) methylation frequently occurs in all stages of CRC; therefore, the aim of this study was to evaluate the clinical performance of a stool DNA-based SDC2 methylation test for detecting CRC in asymptomatic or high-risk CRC populations.

Methods: This multicenter prospective study was conducted to determine the clinical performance of the SDC2 methylation test on stool DNA using real-time polymerase chain reaction.
