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

August 17, 2026 updated by: 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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Eligible subjects shall be aged 45 to 74 years at enrollment, scheduled to receive digestive tract endoscopic screening, willing to complete five-year follow-up as specified by the protocol, and capable of signing the informed consent form.

Description

Inclusion Criteria:

  • 1.Subjects aged 45-74 years at enrollment; 2.Scheduled to undergo digestive tract endoscopic screening; 3.Agree to receive five-year follow-up in accordance with the study protocol; 4.Willing to provide written informed consent.

Exclusion Criteria:

  • 1. Having received upper gastrointestinal endoscopy within one year; 2.History of any type of malignant tumor; 3.Complicated with severe illnesses that reduce screening benefits, such as severe pulmonary, renal, hepatic, cardiovascular, cerebrovascular and hematological diseases; 4.Other conditions assessed by physicians as excessively high risk for endoscopic screening (e.g., hemodynamic instability) or non-beneficial (short life expectancy); 5.Pregnant or lactating women.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Sensitivity of blood multi-gene methylation combined with fecal biomarkers for pan-digestive tract cancer screening, with endoscopy plus pathological biopsy serving as the gold standard
Time Frame: Day 1 At endoscopy and pathological confirmation after enrollment
Day 1 At endoscopy and pathological confirmation after enrollment
Specificity of combined biomarkers for pan-digestive tract cancer screening
Time Frame: Day 1 At endoscopy and pathological confirmation after enrollment
Day 1 At endoscopy and pathological confirmation after enrollment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
