In most cases, lung cancer patients, especially those with early-stage lung cancer, can be cured after surgery, which basically does not affect the survival time. The exact length of time a lung cancer patient can survive after lobectomy is directly related to the patient’s lung cancer condition. For some lung cancer patients who already have lymph node metastasis at the time of surgery, although lobectomy is performed, the treatment effect is often not particularly satisfactory, and adjuvant chemotherapy or other treatments may be required after surgery. Some patients are not sensitive to surgery and chemotherapy, and their survival time may be shortened to 1-3 years.
