Small cell lung cancer is a highly malignant tumor disease. According to the different conditions of patients, the treatment options also vary. At present, the commonly used clinical treatment options include chemotherapy, radiotherapy, surgery and targeted therapy. 1. Chemotherapy: Chemotherapy is to kill cancer cells by using chemical drugs. Commonly used chemotherapy drugs in clinic include etoposide, irinotecan and so on. Bone marrow suppression and adverse reaction of digestive system may occur during the use of drugs. 2. Radiotherapy: small cell lung cancer is highly sensitive to radiotherapy. By receiving local radiotherapy, the growth and reproduction of malignant cells can be effectively inhibited. 3. Surgery: Surgery for small cell lung cancer is less effective. For very early small cell lung cancer, surgery can be considered. 4. Targeted drug therapy: In recent years, targeted drugs and immune-targeted drugs can also be one of the treatment options for small cell lung cancer. At present, more of them are in the stage of clinical research, so it is recommended to consult the doctor. Each small cell lung cancer patient’s condition is different, and the most suitable clinical treatment plan will also be different. It is recommended that patients should formulate their own treatment plan under the guidance of specialists, follow the doctor’s instructions to standardize the treatment, and have regular follow-ups.
