Introduction
1. Direct invasion: Gastric cancer can directly infiltrate the peritoneum and adjacent organs, including the esophagus, liver, pancreas, and transverse colon. 2. Lymphatic metastasis: Cancer cells typically first spread to regional lymph nodes, followed by distant lymph nodes. 3. Hematogenous metastasis: This usually occurs in advanced stages, with the liver being the most common site of metastasis. 4. Peritoneal (implantation) metastasis.

Gastric cancer is a malignant tumor originating from the gastric mucosal epithelium. It ranks first among all malignant tumors in terms of incidence in China. Gastric cancer exhibits marked regional variation in incidence, with significantly higher rates observed in northwestern and eastern coastal regions compared to southern areas. Pain and weight loss are the most common clinical symptoms in advanced gastric cancer. Below, we address the question: Where does gastric cancer commonly metastasize?

Common Sites of Gastric Cancer Metastasis

1. Direct invasion: Gastric cancer may directly infiltrate the peritoneum and adjacent organs, including the esophagus, liver, pancreas, and transverse colon.

2. Lymphatic metastasis: Cancer cells typically first spread to regional lymph nodes, then to distant lymph nodes—such as the left supraclavicular lymph nodes.

3. Hematogenous metastasis: This usually occurs in advanced disease. The liver is the most frequent site of hematogenous metastasis, followed by the lungs, bone marrow, adrenal glands, kidneys, and brain.

4. Peritoneal (implantation) metastasis: When the tumor invades the gastric serosa, cancer cells may detach and implant within the peritoneal and pelvic cavities.

Additional Information: Dietary Considerations for Gastric Cancer Patients

1. Modify dietary patterns: Increase intake of vegetables, fruits, legumes, milk, fresh fish, lean meats, and eggs. Garlic and green tea are recommended.
2. Correct unhealthy eating habits: Avoid binge eating, irregular meal schedules, excessively rapid or hot food intake, and overly hard foods. Limit consumption of smoked, salted, or pickled foods and avoid high-salt diets.
3. Minimize consumption of strong alcoholic beverages and abstain from smoking.
4. Implement measures to prevent grain mold contamination and ensure safe, clean drinking water.

The above outlines the common sites of gastric cancer metastasis. We hope this information proves helpful to you.
