title: Optimal surgical management of Stage I non-small-cell lung cancer in an increasingly aging population: challenges and recent progress.
abstract: Lung cancer remains the main cause of cancer deaths in the USA. The dismal prognosis for non-small-cell lung cancer (NSCLC) despite current advances in chemotherapy is disappointing. In an increasingly aging population, computed tomography screening allows the detection of very early Stage I NSCLC lesions. Although many retrospective trials have indicated better prognosis for those undergoing lobectomy versus sublobar resection (anatomical segmentectomy or wedge resection), the issue remains equivocal. This is particularly true for patients with significant comorbid cardiorespiratory disease compromising postoperative recovery. This review will describe landmark retrospective studies related to the topic, in an attempt to highlight the difficulties associated with surgical decision making. Key factors in the characteristics of the lesions will be examined equally with the ultimate objective of allowing the decision of lobectomy versus sublobar resection to be centered around the need of the individual patient per se. This review article will also provide an insight into ongoing randomized, prospective clinical trials on the subject, investigating into some of the emerging technologies from the laboratory and the clinic that will hopefully enable the provision of a solidly acceptable treatment plan for the Stage I NSCLC patient, with maximum survival rates and low disease recurrence.
