Patients with advanced lung cancer are usually not treated by surgery, but can be treated by chemotherapy, radiotherapy and targeted therapy. 1. Chemotherapy: Lung cancer patients can kill cancer cells through chemotherapy. Non-small cell lung cancer is mainly treated with chemotherapy drugs such as carboplatin, cisplatin, paclitaxel, vincristine, etc. Small cell lung cancer patients are mainly treated with chemotherapy drugs such as cisplatin, carboplatin, etoposide and irinotecan. 2. Radiation therapy: chemotherapy for patients with advanced lung cancer can inhibit the development of tumor, slow down the spread of tumor, and improve the uncomfortable symptoms caused by bone metastasis and brain metastasis in patients with advanced lung cancer. 3. Targeted therapy: Patients with advanced lung cancer can also undergo targeted therapy to kill tumor cells and prolong the survival period of patients, commonly used targeted therapy drugs include gefitinib, crizotinib and bevacizumab.
