Gut Microbiota Clinical Trial
Official title:
Establishment of Individualized Immunotherapy Strategy and Platform for Upper Gastrointestinal Cancer Based on Changes of Intestinal Microbiota
To explore and analyze the relationship between intestinal flora changes and the efficacy of individualized immunotherapy in patients with upper gastrointestinal cancer, and to find new biomarkers to predict the efficacy of immunotherapy, bringing new breakthroughs in tumor diagnosis and treatment.
