Liver cancer lung metastasis is an advanced stage of the disease, and the treatment can choose surgery, chemoradiotherapy, targeted therapy, etc., which are mostly palliative treatments. For patients with liver cancer lung metastasis, when the volume of lung metastatic lesions is small and the distribution area is relatively small, then minimally invasive surgery and radiofrequency ablation surgery can be used to treat the lung lesions, which is relatively safe and easy to perform, with relatively few side effects, and supplemented by radiotherapy after surgery. For patients with liver cancer lung metastasis, when the lung metastatic lesions are large in size and widely distributed in the area, and obvious symptoms have appeared, such as stabbing pain in the chest, malignant pleural effusion, cough, shortness of breath, chest tightness, dyspnea, etc., then radiotherapy, chemotherapy, targeted and immunotherapy, etc. can be chosen according to the specific conditions of the patients, and at the same time symptomatic supportive treatments can be strengthened in order to alleviate the symptoms. Patients with lung metastasis of liver cancer should consult the doctor in time and have individualized treatment under the doctor’s guidance in order to prolong the survival period and improve the quality of life.
