Abstract:

Sublobectomy, include anatomic segmentectomy and non-anatomic wedge resection is an alternative to lobectomy for the surgical treatment of selected patients with early stage non-small cell lung cancer. Sublobar resection can reserve more pulmonary function in these patients. Emerging evidence suggests that sublobar resection may offer survival outcomes approaching that of lobectomy for lung cancer patients whose disease meets the following criteria: stage IA disease with no regional lymph node matastasis; tumor comes up to 2 cm in diameter; located in the periphery of lung; and predominantly ground-glass appearance on CT imaging. Compared with wedge resection, segmentectomy generated the best results. Nevertheless, the evidence is currently still limited, and the above criteria are met only in a minority of patients. Large randomized trials are underway to define the clinical role of sublobar resections, and results are eagerly anticipated. Until that time, lobectomy should still be regarded as the standard therapy for patients with early stage non-small cell lung cancer.

Key words: non-small cell lung cancer, early stage, sublobectomy
