Small cell lung cancer metastatic liver may have digestive symptoms, jaundice, liver ascites, liver failure and other bad effects. 1. Digestive tract symptoms: most patients with small cell lung cancer metastatic liver will suffer from decreased liver function, which will cause digestive tract symptoms, such as nausea, vomiting, loss of appetite, etc. In the long run, patients will suffer from decreased immunity due to malnutrition, and suffer from rapid weight loss, which will lead to the risk of causing more complications. 2. Jaundice: If the metastatic foci compress the hepatic hilar or bile duct area, affecting the function of bile secretion, jaundice may appear, manifested as yellowing of skin, sclera and urine. 3. Hepatic ascites: after metastasis of small cell lung cancer to liver, liver function will be impaired and albumin production will be reduced, which may cause accumulation of fluid in the abdominal cavity, ascites of liver and swelling of lower limbs. 4. Liver failure: metastasis of lung cancer to liver leads to liver failure due to serious damage of liver, which is a more serious condition and requires drug treatment, artificial liver treatment and general supportive treatment to alleviate the development of the disease. No matter which of the above adverse consequences occurs after metastasis of small-cell lung cancer to liver, it is necessary to cooperate with doctors in time to do targeted treatment to prevent further spreading or metastasis of cancer cells.
