Advanced lung cancer is definitely not suitable for surgical resection, because surgery at this time does not significantly prolong the patient’s survival, and surgery may bring serious complications to the patient, so systemic treatment, including chemotherapy, oral targeted drug therapy, immunotherapy, etc., is often the main treatment at this time. However, if the patient is in the middle stage of lung cancer, some patients can undergo surgical resection, and after surgery, according to the pathological stage, some patients also need adjuvant radiotherapy and chemotherapy, and through comprehensive treatment, the middle stage of lung cancer may be cured. There are also some patients with mid-stage lung cancer who are not recommended to undergo surgical resection, and the first choice should be simultaneous radiotherapy and chemotherapy, after which consolidation chemotherapy is also needed, which may also control the tumor and prolong the patient’s life.
