Symptoms of peritoneal metastasis from gastric cancer

summary

Of course, gastric cancer will metastasize. Peritoneal metastasis of gastric cancer is an important factor affecting the choice of treatment and prognosis of gastric cancer. In Chinese mainland, peritoneal metastasis accounted for 53%~60% of gastric cancer metastasis, which exceeded liver metastasis (40%) and other metastasis (3%~7%). Let's talk about the symptoms of peritoneal metastasis of gastric cancer.

Symptoms of peritoneal metastasis from gastric cancer

Direct dissemination: invasive gastric cancer can develop directly into the gastric wall, esophagus or duodenum along the mucosa or serosa. Once the cancer invades the serosa, it is easy to invade the surrounding organs or tissues, such as liver, pancreas, spleen, transverse colon, jejunum, diaphragm, omentum and abdominal wall. When the cancer cells fall off, they can also be planted in the abdominal cavity, pelvic cavity, ovary, rectum and bladder lacunae.

Lymph node metastasis: it accounts for 70% of gastric cancer metastasis. The lower gastric cancer often metastasizes to the lymph nodes below pylorus, below stomach and beside celiac artery, while the upper gastric cancer often metastasizes to the lymph nodes beside pancreas, cardia and above stomach. Advanced cancer may metastasize to the periaortic and supradiaphragmatic lymph nodes. Because of the direct communication between the abdominal lymph nodes and the thoracic duct, it can be transferred to the left supraclavicular lymph nodes.

In a few cases, the tumor broke through the serosa of the gastric wall and appeared necrosis and abscission of the cancer tissue. It fell off to other organs and peritoneum and could grow with implantation; In the late stage, cancerous peritonitis and bloody ascites can occur, and sometimes cancer cells can be found in the extracted ascites. The patients with implantation metastasis are all in advanced stage, and the treatment is more difficult. They are often given intraperitoneal injection of chemotherapy drugs, but because of extensive metastasis, they can only prolong life, but can not be cured.

matters needing attention

Gastric cancer metastasis not only increases the pain of patients, but also increases the difficulty of treatment, and even threatens the lives of patients. Therefore, once there are signs of gastric cancer metastasis, it should be diagnosed and treated as soon as possible. According to the different conditions of patients, it should be treated according to the disease, improve symptoms, control metastasis, and prolong the survival of patients.
