There is no optimal treatment plan for small cell lung cancer, but we need to choose suitable treatment plan such as surgery, radiotherapy, chemotherapy and so on according to the stage and physical condition. The treatment plan for small cell lung cancer is not fixed, and it needs to be chosen according to the patient’s stage, physical condition and other factors, and there is no such thing as the best treatment plan. The main treatment plans include surgery, radiotherapy, chemotherapy and immunotherapy. Generally speaking, early stage small cell lung cancer has limitations, and the preferred treatment plan is surgery and radiotherapy, which can control the patient’s condition well and even achieve long-term remission. For middle and late stage patients with metastases to lymph nodes and distal organs, chemotherapy is the main treatment option, supplemented by radiotherapy and immunotherapy.
