There is no optimal treatment plan for non-small cell lung adenocarcinoma, and the main thing is to choose the most suitable treatment method, which includes surgical resection, radiotherapy, chemotherapy and targeted therapy, etc. The use of medicines should be in accordance with doctor’s prescription. 1. Surgical resection: for relatively early lesions, radical surgical resection can be done, and some of them need to do lymph node dissection. 2. Radiotherapy: for postoperative adjuvant treatment or palliative treatment for patients with middle or advanced disease, radiotherapy can be chosen, and local radiotherapy or particle implantation is usually chosen. 3. Chemotherapy: a common treatment plan for malignant tumors, to kill tumor cells as much as possible, commonly used drugs are cisplatin and so on. 4. Targeted therapy: some patients are accompanied by gene mutation, so they can choose targeted therapy, and commonly used targeted drugs include gefitinib. It is recommended that non-small cell lung adenocarcinoma patients should seek medical treatment in time and standardized treatment under the guidance of clinicians, so as to avoid delaying the condition.
