In the eighth edition of TNM staging data, the 5-year survival rate for non-small cell lung cancer is about 5% in advanced stage, that is, stage IVB at the time of detection, when the lung cancer is found to have metastasis to other parts of the body, which means that few people can live beyond 5 years. If it is stage IVA, that is, although there are distant metastases, such as pleural metastases and pleural fluid, through effective treatment, the 5-year survival rate is about 10%. If the disease is slightly less severe, that is, locally advanced, although inoperable, such as the lymph nodes of the opposite lung gate, or invasion of the pericardium or surrounding large blood vessels, through effective radiotherapy and chemotherapy, the 5-year survival rate can reach about 30%. The above are the data of large samples. Nowadays, the treatment of lung cancer is constantly making breakthroughs, and depending on the individual, patients can just receive proper treatment according to different types.
