Patients with advanced hepatocellular carcinoma and lung cancer cannot be cured from the perspective of clinical therapeutics, but medical interventions can be used to alleviate patients’ pain and improve their quality of life in the late stage. Patients with hepatocellular carcinoma will have obvious pain in the liver area, and late complication of pulmonary metastasis will lead to large amount of pleural effusion and respiratory difficulties. For primary liver tumor with extensive abdominal metastasis, it will also manifest as ascites, which can also be treated by intermittent puncture for fluid drainage, as well as intravenous anti-infection treatment, because some patients are prone to complicate spontaneous peritonitis.
