The five-year survival rate after chemotherapy for early stage lung cancer can reach 75%, while that for advanced stage patients is only 3%-5%, which needs to be determined in combination with staging and treatment plan.
Generally, early stage lung cancer patients are treated with surgical resection, and chemotherapy is mostly used as an auxiliary means to reduce the chances of recurrence and metastasis, because the survival period will be relatively longer, and some of the patients will not even have an impact on the normal life span.
If it is in advanced stage, the cancer cells have already appeared systemic metastasis and spread, the effect of chemotherapy is not very ideal, and the survival period of patients is shorter, which may only be a few months; if it can be combined with targeted drugs, the survival period can be prolonged.
Survival period of chemotherapy for lung cancer will be affected by treatment plan and stage, which is not completely fixed, so it is recommended to follow the doctor’s instruction to actively treat the disease.
