title: Minimally invasive resection of early lung cancers.
abstract: Low-dose computed tomography (LDCT) screening decreases lung cancer mortality in high-risk individuals and has now been approved and adopted for lung cancer screening in the United States. As more LDCT lung cancer screening programs are implemented, more patients with early-stage lung cancer who could benefit from surgical intervention will be identified. Although lobectomy currently remains the standard of care for early-stage non-small-cell lung cancer (NSCLC), thoracic surgeons are increasingly adopting minimally invasive surgery via thoracoscopy as a viable-and perhaps even preferred-approach for select lung cancer resections. Video-assisted thoracic surgery (VATS) lobectomy has been associated with decreased perioperative morbidity, and similar rates of locoregional recurrence and cancer-free survival can be achieved compared with the standard open surgical procedure. However, as lung cancers are detected at earlier stages, the optimal extent of lung resection for long-term cure continues to be investigated. For patients with very small-sized lung tumors and indolent lesions, cancer-free survival may not necessarily be compromised by undergoing less invasive approaches that intentionally resect less lung tissue, such as sublobar resections (eg, segmentectomy and wedge resection). This review looks at the current data and guidelines for thoracoscopic resection of stage I NSCLC and discusses the potential for limited lung resection in patients with the disease.
