Prospectively Predict the Efficacy and Explore the Mechanism of Treatment of Gastrointestinal Tumors Based on Peripheral Multi-omics Liquid Biopsy

Recruiting
Conditions
Advanced or Late Stage Gastrointestinal Cancer
Interventions
Device: EV-array detection
Registration Number
NCT05427227
Lead Sponsor
Peking University
Brief Summary

Dynamic multiomics detection of plasma derived exosomes to explore the efficacy and mechanism of anti-HER2, immunotherapy and anti-CLDN18.2 of gastrointestinal cancer.

Detailed Description

The investigators will recruit 500 advancer/late-stage gastrointestinal cancer patients.Blood and tumor tissue will be collected at treatment baseline, every time point response till disease progression. All samples will be processed by exosomes proteome detection to explore the efficacy and mechanism of anti-HER2, immunotherapy and anti-CLDN18.2 of gastrointestinal cancer.
