Five papers showed a lower N1 nodal upstaging with video-assisted thoracic surgery (VATS) compared to open surgery in patients with cStage-I NSCLC . This finding questions the oncologic quality of minimal invasive lung cancer surgery, especially the quality of hilar and intrapulmonary lymh node dissection. However, these retrospective studies did not include analysis of central tumor location, although central tumors have a reported higher chance of N1 upstaging . Possibly, this creates a selection bias as surgeons might select central lesions deliberately for open surgery in line with initial VATS feasibility reports
