Advanced stage lung cancer firstly needs to distinguish whether it has metastasized to the skull, liver, bones, or other organs, such as in the lungs, adrenal glands, etc. Secondly, it also depends on the specific number and scope of metastases, the impact on the function of metastatic organs, etc. Meanwhile, the patient’s physical condition, pathology, economic factors, etc. should be considered. Without standard treatment, advanced lung cancer will certainly not have any miracle. However, if it is lung adenocarcinoma and there is a sensitive gene mutation, targeted therapy has the potential to produce a very good miracle. Even if there is no sensitive gene mutation, as long as the patient is in good health, chemotherapy can be done, and if appropriate, immunotherapy can be done, which usually will have good results.
