Overview
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, and feces from the study subjects. We combined 16S rRNA sequencing and metabolomics to explore the differences in microbial and metabolic characteristics between gastric cardia cancer and non-cardia gastric cancer for early screening of gastric cancer.
Interventions
- Other Detection of biological samples based on multi-omics analysis
In this study, we combined microbiological (16SrRNA) and metabolomic mass spectrometry to study the changes in microbial populations and metabolic profiles of various samples such as feces, serum, and saliva, and screen key differential markers.
Primary outcome measures
- Early gastric cancer detection rate [Time frame: 36 months]
Eligibility criteria
Inclusion criteria
- Study population signing informed consent form

- The study population must underwent endoscopic examination and was confirmed by pathological diagnosis as gastric cancer: including high-level intraepithelial neoplasia, early gastric cancer, and advanced gastric cancer.
Exclusion criteria
- Those who have undergone gastrointestinal surgery within the past 1 year; Patients who have undergone neoadjuvant chemotherapy and have developed tumors in the residual stomach after previous partial gastrectomy.
