Ascites in advanced stage of hepatocellular carcinoma slowly subsided, the reason is that the treatment is effective and the condition has improved. Patients with advanced stage of liver cancer are prone to ascites, mainly because tumor cells infiltrate into the peritoneum, leading to peritoneal metastasis and destroying the permeability of peritoneum. In addition, liver cancer is usually combined with cirrhosis, which leads to portal hypertension with hypoproteinemia, resulting in ascites. When ascites slowly disappears in advanced stage of liver cancer, it is usually because the symptomatic treatment of ascites has more obvious therapeutic effect, and the condition is better, such as the use of diuretics, albumin transfusion and so on. Although ascites slowly disappears, it is still necessary to actively treat liver cancer, follow the doctor’s instruction to strictly use medicines, and go to the hospital for regular checkups, such as liver function test, albumin and so on. Patients with advanced stage of liver cancer usually need to take low-salt diet and eat more nutritious food to replenish the nutrients needed by the body and maintain the normal physiological function of the organism. If there are other discomforts in the body, they should inform the doctor in time to avoid adverse effects.
