This is an observational study with a case control design. This study included patients with gastric cancer confirmed by pathological diagnosis of gastric tissue, and matched the control population according to age, gender, etc. In this study, researchers collected clinical information and multiple biological samples such as saliva, serum, tissue,and feces from the study subjects. We combined multi-omics approach to explore the differences between gastric cardia cancer and non-cardia gastric cancer for early screening of gastric cancer.
