If ascites and swollen feet appear in the late stage of liver cancer, the survival period is about 3-6 months. Firstly, liver cancer is combined with portal vein thrombosis, which leads to obstruction of blood return, resulting in ascites and swollen feet. It may also be related to the decrease of liver function in combination with hepatocellular carcinoma and the decrease of albumin synthesis, which leads to a large increase of fluid in the abdominal cavity. Swollen feet may also be associated with poor nutritional status of liver cancer, resulting in reduced albumin synthesis, which may also lead to swollen feet. At this time, we can strengthen nutrition, eat a high-protein diet, and supplement albumin with diuretic if necessary, which can help reduce foot swelling. In any case, if ascites and foot swelling appear in late stage of liver cancer, the survival period is very short.
