简要总结
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.
详细描述
- Compare the composition of intestinal flora of patients before and after immunotherapy and in patients with different therapeutic effects of immunotherapy.
- Combine the results above with the patient's blood sample, which is carried out from the metabolic level.
- Combine the pathological data of the patient to determine the staging and pathological types, and use blood samples to detect metabolites to find out different metabolites.
- the metabolic data and the flora data are associated with the analysis to find the bacteria species with higher correlation with the differential metabolites to guide the subsequent animal experiments.
