Whether invasive adenocarcinoma of the lung can be cured depends on the extent of invasion and the number of lymph nodes, as well as whether there is a combination of distant metastases. If the tumor is small, such as less than 3 cm or less than 5 cm, and there is no lymph node metastasis in the lung or mediastinum, and there is no distant metastasis, the lung invasive adenocarcinoma can be cured by surgical resection. If lymph node metastasis or pleural cavity metastasis, bone metastasis or brain metastasis occur, there is no cure for invasive adenocarcinoma. However, there are many treatments available for pulmonary invasive adenocarcinoma, such as chemotherapy, immune checkpoint inhibitors, targeted drugs, etc., which extend the survival of patients with pulmonary invasive adenocarcinoma significantly. Therefore, pulmonary invasive adenocarcinoma can go for treatment in theory, and whether it can be cured or not depends mainly on the stage.
