The survival time of patients with advanced lung tumors is clinically expressed mainly in terms of five-year survival rate, generally the five-year survival rate of patients with advanced non-small cell lung cancer is around 10%, while the data of patients with advanced small cell lung cancer is even lower, around 5%, and the data of patients with lung sarcoma and other patients are not clear yet. Advanced lung tumors include advanced primary bronchial lung cancer, advanced lung sarcoma, etc., in which primary bronchial lung cancer can be further divided into non-small cell lung cancer and small cell lung cancer, and the research data of patients with advanced non-small cell lung cancer confirms that the five-year survival rate is around 10%, and most of the patients with advanced lung cancer have a survival time of less than five years. Small cell lung cancer is the more malignant type of lung cancer, and its five-year survival rate data is even lower, only about 5%, with most advanced patients surviving less than a year. Lung sarcoma is also highly malignant, but no specific five-year survival data are available for it.
