After the diagnosis of lung minimally invasive adenocarcinoma is confirmed, surgical treatment should be preferred, with regular follow-up and review after surgery. Microinvasive adenocarcinoma of lung belongs to the results of pathological diagnosis, which indicates that the stage of lung cancer is early, most of the prognosis is good, and treatment should be actively carried out after diagnosis. Surgery should be the first choice for lung adenocarcinoma at this stage. Relevant examinations such as blood routine, biochemistry, coagulation, cardiac function, etc. should be completed before surgery to fully assess the patient’s physical condition. If the patient’s physical condition permits, surgery should be carried out in time, and at present, most hospitals can choose minimally invasive subthoracic treatments such as lung wedge resection and segmental resection. The staging of micro-invasive adenocarcinoma of lung is early, and there is no need for radiotherapy or chemotherapy after surgery. Regular review can be done, including blood tumor markers, lung CT and other imaging examinations. Most of the micro-invasive adenocarcinoma of lungs have good prognosis and should be treated actively, and usually pay attention to adjusting living habits and quitting smoking.
