What is the chance of survival in chemotherapy for advanced lung cancer cannot be generalized, and it is decided according to the effect of chemotherapy and the patient’s own physical condition. Generally speaking, the 5-year survival rate is about 10%. After chemotherapy is administered to patients with advanced lung cancer, if the immunity and physical quality of the patient’s body are stronger and the result of chemotherapy is better, and the proliferation and metastasis of tumor cells are effectively controlled by chemotherapy, the higher the chance of survival. However, if the patient’s immunity is poor or the chemotherapy fails to achieve the desired effect, which cannot control the disease in time and cause the tumor cells to spread or metastasize, the patient’s condition will be affected to a certain extent and the chance of survival will be reduced. When in the advanced stage of lung cancer, standardized chemotherapy should be carried out under the guidance of professional physicians, and if there is any adverse reaction, professional doctors should be informed in time.
