After the Lung Cancer Study Group published its seminal trial in 1995, anatomic lobectomy was established as the gold standard surgical therapy for patients with resectable non-small cell lung cancer (NSCLC) (1). However, the increasing utilization of low-dose helical computed tomography (CT) as a screening strategy in high-risk patients and the resultant increase in the frequency of diagnosis of smaller, more peripheral lesions has reinvigorated interest in the oncologic merits of sublobar resection (2). A host of retrospective studies have suggested that sublobar resection provides equivalent locoregional disease control while sparing lung parenchyma (3-5). Consequently, sublobar resection is frequently offered to patients with marginal pulmonary function or to those whose comorbidities render them to be otherwise borderline surgical candidates.
