The five-year survival rate of lung adenocarcinoma is more than 70% in early stage and only 20% in late stage. The cure rate of lung adenocarcinoma is mainly related to the treatment plan and staging. Generally speaking, if lung adenocarcinoma is found in time and in the early stage, radical surgery can be carried out to remove the lesions through surgery, or with radiotherapy and chemotherapy, the five-year survival rate can still reach more than 70%. However, if lung adenocarcinoma is found late and misses the best treatment time, and the cancer cells have extensive metastasis to lymph nodes and distal organs, then it is more difficult to be treated, and clinically, radiotherapy, chemotherapy, targeted therapy and immunotherapy are mainly used to prolong the survival cycle of the patients, and the cure rate is only about 20%.
