Commonly used treatment options for lung cancer metastasis to liver lymph include drug chemotherapy, targeted therapy, radiotherapy, etc. The use of drugs should follow doctor’s instructions. 1. Drug chemotherapy: after lung cancer metastasizes to liver lymph nodes, chemotherapy drugs such as 5-fluorouracil, cyclophosphamide, adriamycin and so on can be used for systemic chemotherapy. 2. Targeted therapy: patients can be treated with molecular targeted drugs such as bevacizumab and erlotinib, which can block the growth and reproduction of tumor cells and improve symptoms. 3. Radiotherapy: radiotherapy can kill cancer cells, control the development of lesions and relieve pain, and radiotherapy combined with chemotherapy can improve the curative effect. It is suggested that patients should go to the hospital in time, actively cooperate with doctors, relax, take more rest and develop good habits of life and work.
