Metastatic symptoms of liver cancer?

summary

Metastasis of liver cancer is a very common phenomenon. There are no obvious symptoms in the early stage of liver cancer, and metastasis is easy to occur in the late stage due to the spread of cancer cells. Liver metastases are often multicentric, with poor prognosis and survival time less than 6 months. Although the median survival time of single liver metastasis can be extended to 18-20 months, the 5-year survival rate is almost zero. Now let's learn about some symptoms of liver cancer metastasis.

Metastatic symptoms of liver cancer?

1. Hematogenous metastasis: intrahepatic hematogenous metastasis is the earliest and most common, which can invade the portal vein and form tumor thrombus. Tumor thrombus falling off in the liver can cause multiple metastatic lesions. Obstruction of main portal vein tumor thrombus can cause portal hypertension and intractable ascites. After liver cancer cells invade the hepatic vein, they can enter the systemic circulation and have extrahepatic metastasis. The highest rate of metastasis is in the lung. It can also be hematogenous metastasis to all parts of the body. Adrenal gland, bone, kidney, brain and other organs are more common. Hematogenous metastasis is common in hepatocellular carcinoma.

2. Lymph node metastasis: local metastasis to hilar lymph nodes is the most common, can also be transferred to supraclavicle, aorta, pancreas, spleen and other lymph nodes, cholangiocarcinoma with lymph node metastasis in the majority. Lymph node metastasis accounted for only 12.6% of the total metastasis.

3. Implantation metastasis: occasionally, such as implantation in the retroperitoneal formation of bloody ascites, women can also have ovarian metastasis. Direct infiltration: liver cancer usually has less direct infiltration of adjacent organs, but occasionally it can spread directly to adjacent tissues and organs, such as diaphragm, stomach, colon, omentum, etc.

matters needing attention

1. First of all, it is necessary to know whether liver cancer can be transmitted. Although there is a phenomenon of family aggregation of liver cancer in medical cases, the reason is the cross infection of hepatitis, not the infection of liver cancer. 2. We should also put an end to the infection of viral hepatitis. In contact with liver cancer patients, if liver cancer patients are caused by hepatitis B virus, we should pay attention to protection, especially those children and the elderly with weak constitution. But liver cancer is not contagious. There is no need to worry about it. 3. First of all, we should prevent viral hepatitis. 4. Develop good living habits. In people's good living habits, the first thing to prevent liver cancer is to quit smoking and alcohol. Secondly, to develop good eating habits, we should start from eating hygiene and living habits. Wash your hands frequently and divide your meals. Cannot eat moldy, pasted food, this kind of food contains aflatoxin, this kind of material causes cancer. Finally, we should emphasize the quality of sleep.
