Clinical Study of Surgical Treatment of Non-small Cell Lung Cancer 
10 mm or Less in Diameter Under Video-assisted Thoracoscopy

The reasonable operational manner of non-small cell lung cancer (NSCLC) in early stage is in dispute. This clinical study is to investigate the operational manner of NSCLC 10 mm or less in diameter. The clinical datas of 46 cases with NSCLC 10 mm or less in diameter were retrospectively analyzed in our hospital from July 2013 to March 2016. Thin-section computed tomography (CT) was done on all cases with 46 pulmonary nodules (5 solid nodules, 23 mGGOs and 18 pGGOs). Lobectomy, wedge resection and segmentectomy with lymph node dissection may be performed in patients according to age or heart and lung function. CT-guided Hook-wire precise localization was done on 7 cases. Lobectomy and systematic lymph node dissection under video-assisted thoracic surgery (VATS) were performed in patients with 23 pulmonary nodules (15 mGGOs, 4 pGGOs and 4 solid nodules ), among wich, only one patient with N2 lymph node matastasis was found. Wedge resection and selective lymph node dissection under VATS were done in patients wit
