Using exosome analysis to diagnose upper gastrointestinal cancers

Plasma Extracellular Vesicle Quantitative Proteomic Analysis for Early Diagnosis of Upper Gastrointestinal Cancers

Beijing Friendship Hospital · NCT06278064

This study is trying to see if analyzing tiny particles in the blood can help doctors find upper gastrointestinal cancers earlier in patients compared to those with benign conditions or healthy individuals.

What this trial studies

This observational study collects and analyzes plasma samples from patients with upper gastrointestinal cancers, benign diseases, and healthy controls to identify protein biomarkers for early diagnosis. Utilizing advanced proteomics techniques, including Data-Independent Acquisition (DIA) and single-vesicle membrane protein detection, the study aims to quantify protein content within exosomes. A comprehensive database of tumor-specific exosome proteins will be constructed, and diagnostic models will be evaluated for their potential in early cancer detection. External validation of identified biomarkers will ensure their reliability across diverse patient populations.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with upper gastrointestinal cancers or benign diseases who have provided plasma samples prior to surgical treatment.

Not a fit: Patients who have received prior anti-tumor treatments or have other systemic tumors may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier and more accurate diagnoses of upper gastrointestinal cancers, improving patient outcomes.

How similar studies have performed: Similar studies utilizing exosome-based biomarkers have shown promise in cancer diagnostics, suggesting a potential for success in this approach.
