Anatomic Segmentectomy in the Treatment of Stage I Non-Small Cell Lung Cancer

Anatomic segmentectomy can be performed safely by an open or VATS approach. Segmentectomy outcomes compare favorably with standard lobectomy for stage I NSCLC. Margin/tumor ratios of less than 1 are associated with a higher rate of recurrence. Lobectomy should be considered as primary therapy when such margins are not obtainable with segmentectomy in the good-risk patient.
