What is the metastatic pathway of gastric cancer

In recent years, gastric cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of gastric cancer, we humans should understand the metastasis pathways of gastric cancer:

1. Direct spread Invasive gastric cancer can spread directly along the mucosa or serosa into the stomach wall, esophagus or duodenum. Once the cancer invades the serosa, it is easy to infiltrate the surrounding organs or tissues such as the liver, pancreas, spleen, transverse colon, jejunum, diaphragm, greater omentum and abdominal wall. When cancer cells fall off, they can also be implanted in the abdominal cavity, pelvic cavity, ovary and rectovesical pouch.

2. Lymph node metastasis accounts for 70% of gastric cancer metastasis. Cancer in the lower part of the stomach often metastasizes to the lymph nodes below the pylorus, below the stomach, and around the celiac artery, while cancer in the upper part often metastasizes to the lymph nodes around the pancreas, around the cardia, and above the stomach. Advanced cancer may metastasize to the lymph nodes around the aorta and above the diaphragm. Since the abdominal lymph nodes are directly connected to the thoracic duct, they can metastasize to the left supraclavicular lymph nodes.

3. Hematogenous metastasis: Cancer cells can be found in the peripheral blood of some patients. They can metastasize to the liver through the portal vein and may reach the lungs, bones, kidneys, brain, meninges, spleen, skin, etc.

The above is the metastasis pathway of gastric cancer. Everyone should pay attention to it. Expert Tips: If you have symptoms of disease, do not delay diagnosis. Go to a regular hospital for treatment in time to avoid delaying the disease and causing serious consequences.
