A total of 34 pairs of gastric samples, including gastric adenocarcinoma and their matched non-tumor tissue samples, were collected. *Tumor staging was determined by the TNM system. The system is based on the extent of the tumor (T), the extent of spread to the lymph nodes (N), and the presence of distant metastasis (M). A number is added to each letter to indicate the size or extent of the primary tumor and the extent of cancer spread.
