A Multicenter Prospective Observational Cohort Study for Digestive Tract Tumor Screening Using Multi-Target Blood and Fecal Biomarkers

17. august 2026 opdateret af: Xijing Hospital

A Multicenter Prospective Observational Cohort Study on Digestive Tract Tumor Screening Based on Combined Detection of Multi-Target Blood and Fecal Biomarkers

This project aims to evaluate the sensitivity and specificity of combined blood multi-gene methylation and fecal biomarkers for pan-digestive tract cancer screening, so as to establish a novel technical system for the early diagnosis of pan-digestive tract cancers.Individuals scheduled to receive digestive tract endoscopy are enrolled. Blood and stool samples are collected prior to endoscopic examination for detection of blood multi-gene methylation, fecal immunochemical test (FIT) and calprotectin. Endoscopic procedures are then performed. Following completion of baseline endoscopic screening, all enrolled participants will be followed up for 5 years. The primary endpoint of this study is the sensitivity and specificity of blood multi-gene methylation combined with fecal biomarkers in screening for pan-digestive tract cancers.
