Some patients in the middle stage of lung cancer are able to have surgery. Whether lung cancer can be operated depends on whether the patient’s physical condition can tolerate surgical treatment and the actual pathological staging. Systemic assessment of the patient, such as the presence of risk factors like hypertension, diabetes, coronary heart disease, etc., and the condition of lung function, etc., will be conducted. Patients with intermediate stage lung cancer have already developed metastasis in peripheral tissues and regional lymph nodes, but no distant metastasis, so most of the patients can undergo surgery as long as there is no contraindication to surgery. Depending on the condition of each patient with intermediate stage lung cancer, the duration of surgical treatment is also different. If the lesion of mid-stage lung cancer is not extensive, radical resection of lung cancer can be performed first, and chemotherapy or radiotherapy can be given after surgery. If the lesion is large and radical resection is difficult, preoperative neoadjuvant radiotherapy can be performed first, followed by radical surgery and postoperative chemotherapy or radiotherapy. Once diagnosed, patients with intermediate stage lung cancer are recommended to go to regular hospitals as soon as possible for consultation and have their treatment plan formulated by professional doctors.
