Symptoms of intestinal metastasis of gastric cancer?
summary
We know that once gastric cancer metastases, it is usually a reflection of the aggravation of the disease. How does gastric cancer metastasize? In fact, gastric cancer has certain metastasis pathways, through which cancer cells can be transferred to all parts of the body. Symptoms of intestinal metastasis of gastric cancer? Let's talk about it.
Symptoms of intestinal metastasis of 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.
Hematogenous metastasis: gastric cancer cells or tumor thrombi may occur in some patients and circulate to other organs of the body through blood circulation. It can be metastasized to liver, lung, bone, kidney, spleen, brain, meninges and skin, and also to ovary to form Krukenberg's carcinoma or ovarian mucinous cell carcinoma. Hematogenous metastasis usually occurs in the advanced stage of gastric cancer. In addition to the treatment of the primary tumor, it is also necessary to treat the metastatic tumor.
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.
