Lobectomy with intrathoracic nodal dissection remains the standard of care for early stage (tumor size ≤ 3.0 cm) peripheral non–small cell lung cancer (NSCLC). This practice is primarily influenced by data from the mid-1990s associating limited resection (segmentectomy or wedge resection) with increased recurrence rate and mortality compared with lobectomy (Ginsberg et al. Ann Thorac Surg. 1995;60:615). Recent advances in video and robot-assisted thoracic surgery, as well as the implementation of lung cancer screening, improvement in minimally invasive diagnostic modalities, and neoadjuvant therapies have driven the medical community to revisit the role of sublobar lung resection.

Two newly published large randomized control multicenter multinational trials (Saji et al. Lancet. 2022;399:1670 and Altorki et al. N Engl J Med. 2023;388:489) have challenged our well-established practices. They compared overall and disease-free survival sublobar to lobar resection of early stage NSCLC (tumor size ≤ 2.0 cm and negative intraoperative nodal disease) and demonstrated noninferiority of sublobar resection with respect to overall survival and disease-free survival. While the sublobar resection in the Saji et al. trial consisted strictly of segmentectomy, the majority of sublobar resections in the Altorki et al. trial were wedge resections. Interestingly, both trials chose lower cut-offs for tumor size (≤ 2.0 cm) compared with the Ginsberg trial (≤ 3.0 cm), which could arguably have accounted for this difference in outcomes. In summary, these emerging data are here to tell us a new story by supporting more limited anatomical lung resection options for our patients with early stage NSCLC.
