In clinical practice, survival after lung cancer recurrence is usually assessed using the 5-year survival rate, where the five-year survival rate is 73% if it is stage IA, and 58% if it is stage IB. For stage IIA, IIB, IIIA, IIIB and IV, the survival rate is 46%, 36%, 24%, 9% and 2% in that order. The specific survival period also needs to be decided according to the patient’s own situation. After the recurrence of lung cancer, if the condition keeps deteriorating, the survival rate will be greatly reduced. If the condition improves after active treatment, the survival rate will increase. Secondly, the survival rate also depends on the treatment effect of the patient, if the effect is obvious after treatment, the survival rate will be improved. If the treatment fails to achieve the ideal effect by means of chemotherapy and radiotherapy, the survival rate will be reduced. Survival rate of lung cancer recurrence is determined by many factors, besides considering the severity of the disease, physical recovery should also be considered. It is suggested that patients should go to regular hospitals in time and listen to the advice of professional doctors.
