Advanced or Late Stage Gastrointestinal Cancer Clinical Trial
Official title:
A Clinical Study Initiated by Investigator:Prospectively Predict the Efficacy and Explore the Mechanism of Precise Treatment of Gastrointestinal Tumors Based on Peripheral Blood Multi- Omics Liquid Biopsy
Dynamic multiomics detection of plasma derived exosomes to explore the efficacy and mechanism of anti-HER2, immunotherapy and anti-CLDN18.2 of gastrointestinal cancer.
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. ;
