Early-stage non-small cell lung cancer: the required type of resection (lobar vs. sublobar) remains unanswered

In 1973, Jensik et al. suggested that segmentectomy might be an adequate resection for patients with T1 N0 non-small cell lung cancer (NSCLC) (1). In 1982, the North American Lung Cancer Study Group initiated a randomized, prospective trial comparing segmentectomy or wedge resection with lobectomy for patients with T1N0 NSCLC.
