Overview
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.

Outcomes
Primary Outcomes
Tumor associated proteins expression level of exosomes
Time Frame: Treatment baseline; Up to 2 months from the initial treatment; From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 100 months
90 tumor associated proteins' expression level of plasma derived exosomes at treatment baseline, second time point response and disease progression time point will be recorded.
