Brief summary
In this project, based on the information of advanced gastric/gastroesophageal junction cancer in evolution under immunotherapy combined with chemotherapy treatment, we will integrate multi-omics dynamic data to identify essential features that correlate to therapeutic effects of immunotherapy therapy, screen potential molecular markers/dominant microbiota for predicting the efficacy of immunotherapy and establish a multimodal predictive model for patients that benefit from immunotherapy. Our project could provide evidence to predict response to immunotherapy for patients with advanced gastric/gastroesophageal junction cancer and potentially optimize the clinical decision-making about therapy for advanced gastric/gastroesophageal junction cancer.
Detailed description
Main objective: to extract and identify multi omics information tags related to the efficacy of immunotherapy for advanced gastric / gastroesophageal junction cancer Secondary objective: to construct and validate the efficacy prediction model of chemotherapy combined with immunotherapy for gastric cancer, in order to optimize the scheme decision of advanced gastric cancer treatment Exploratory purpose: to screen potential molecular markers / dominant flora for predicting the efficacy of immunotherapy in patients with advanced gastric / gastroesophageal junction cancer
Interventions
Peripheral blood, coating, saliva, and feces on the tongue and clinical data of patients with advanced gastric cancer patients who received chemotherapy combined with immunotherapy will be collected.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Objective Best Tumor Response | 12 months | Response using Response Evaluation Criteria In Solid Tumors (RECIST) criteria. Complete Response=disappearance of all target lesions; Partial Response=30% decrease in sum of longest diameter of target lesions; Progressive Disease=20% increase in sum of longest diameter of target lesions; Stable Disease=small changes that do not meet above criteria. |
| Overall Survival | 60 months | Overall survival is the duration from diagnosis to death. For patients who are alive, overall survival is censored at the last contact. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free Survival | 36 months | The period from diagnosis until disease progression or death on study, whichever occurred first. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Survival rate of 12 month | 12 month from the diagnosis | The proportion of people who are still alive within 12 month from the diagnosis |
