In the past fifty years, the early non-small cell even tiny the standard operation for lung cancer has been a lobectomy plus lymph node cleaning, while the Sublobar resection is considered to be older patients, patients with severe lung disease, high-risk patients with lung cancer and other serious diseases proneness to surgery. In recent years, due to the widespread use of clinical CT scans, more early lung cancer, especially ground-glass opacity (GGO) -based "inert" lung cancer was found, and due to population aging caused by elderly patients with lung cancer As well as multiple primary lesions of lung cancer patients gradually increased, Sublobar resection has been new attention. However, Sublobar resection for small lung cancer patients or lung cancer patients with radiographic nodules (GGO), whether the operation is sufficient to be further studied. If the Sublobar resection retains sufficient lung function, and has reached or close to the lobectomy of the oncology prognosis, Sublobar resection can be placed in early non-small cell lung cancer treatment of the first team.
