Based on the 5-year survival rate of patients with stage II lung adenocarcinoma to roughly assess, the cure rate of patients with intermediate stage lung adenocarcinoma may be around 55%. At present, clinical cure for malignant tumors usually refers to clinical cure, which is the percentage of patients who survive for more than 5 years after various comprehensive treatments. The clinical staging of lung adenocarcinoma can be divided into stage I, II, III and IV. Generally, stage I lung adenocarcinoma belongs to the early stage, stage II lung adenocarcinoma belongs to the middle stage, stage III lung adenocarcinoma belongs to the middle-late stage and stage IV lung adenocarcinoma belongs to the late stage. At present, there is no clear data to show the cure rate of patients with intermediate stage lung adenocarcinoma, but some data show that the 5-year survival rate of patients with stage II lung adenocarcinoma is about 55%, from which it can be roughly estimated that the clinical cure rate of patients with intermediate stage lung adenocarcinoma is about 55%. It is recommended that patients actively cooperate with doctors to improve the clinical cure rate.
