Lymph Node Evaluation Achieved by Open Lobectomy Compared With Thoracoscopic Lobectomy for N0 Lung Cancer

In our hands, significantly more lymph nodes were dissected, and a higher percentage of patients were upstaged to N1/N2, during open lobectomy compared with VATS lobectomy in patients with clinical stage N0 lung cancer. Although this did not translate into improved survival at 3 years, concern is raised about the adequacy of lymph node dissection during VATS lobectomy.
