The survival period after lobectomy for lung cancer mainly depends on the size of the tumor, the metastasis of lymph nodes, and what kind of treatment the patient can receive after surgery. If the lung cancer with stage I pathological stage after lobectomy, the 5-year survival rate after surgery is over 80%; if the lung cancer is stage II, the 5-year survival rate after surgery is about 60%; if the lung cancer is stage III, the 5-year survival rate after surgery is about 40%. In conclusion, the survival after lung cancer lobectomy is closely related to the pathological stage, and if the lung cancer is stage II or above, postoperative adjuvant chemotherapy and radiotherapy are required, which can further improve the progression-free survival time and reduce the recurrence after surgery. In conclusion, the survival of lung cancer after lobectomy depends on the type of pathology.
