For non-small cell lung cancer such as squamous lung cancer and adenocarcinoma, invasion of large blood vessels or large airways means serious local invasion, and the effect of surgery is inferior to simultaneous radiotherapy, do not operate. Internationally, the five-year survival rate of barely operated lung cancer invading large blood vessels and trachea is only 7% (the result of 3540 cases of surgery), and the five-year survival rate of such patients with simultaneous radiotherapy is about 15%, and the five-year survival rate of such patients in radiotherapy department of our hospital is over 20%. Lung cancer patients and their families are advised that the five-year survival rate is the golden indicator for your choice of treatment plan. Individual differences cannot be estimated, and doctors cannot guarantee a good outcome for every single one. But all other things being equal, there is one truth: the higher the five-year survival rate of your treatment plan, the better your chances of being cured.
