Details and patient eligibility

About

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

Full 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.
