What are the pathways of gastric cancer metastasis

summary

If gastric cancer can be treated as early as possible, it must be controlled as soon as possible. My aunt can't control her condition after lymph node metastasis. It is necessary to have a comprehensive understanding of some cases of metastasis. Let's take a look at the pathways of gastric cancer metastasis.

What are the pathways of gastric cancer metastasis

One is blood metastasis. Some patients may develop gastric cancer cells or tumor thrombi, which circulate to other organs of the body through blood circulation. It can metastasize to liver, lung, bone, kidney, spleen, brain, meninges and skin, and also to ovary to form ovarian Krukenberg's carcinoma or ovarian mucinous cell carcinoma. Hematogenous metastasis often occurs in the late stage of gastric cancer. In addition to the treatment of the primary tumor, the metastatic lesions should also be treated.

Second: direct spread. After invading the gastric wall, the cancer develops in depth and breaks through the serous layer. It can directly invade the adjacent organs and tissues. The omentum, liver, pancreas and transverse colon are common, followed by jejunum, diaphragm and abdominal wall. Direct spread is related to the surgical method and radical resection. It usually spreads to the adjacent organs, such as liver, etc. it can be resected when the scope is small, but it is difficult to resect when the scope is large.

Third: lymph node metastasis. Gastric cancer is an important way to spread and occurs earlier. With the growth of cancer, the deeper and wider the invasion of gastric wall, the more chance of metastasis.

matters needing attention

Once metastasis of gastric cancer occurs, it indicates that the condition is getting worse. In addition to timely prevention, timely diagnosis and treatment is very important when abnormalities are found.
