Recurrence and Survival Outcomes After Anatomic Segmentectomy Versus Lobectomy for Clinical Stage I Non–Small-Cell Lung Cancer: A Propensity-Matched Analysis

This single-institution retrospective study used propensity score matching to compare long-term outcomes of anatomic segmentectomy vs lobectomy for early stage non-small cell lung cancer.   A total of 312 pts were matched in each group.  Locoregional and overall recurrence rates were similar between the groups.  Freedom from recurrence (70% for segmentectomy vs 71% for lobectomy) at 5 years was similar.  5-year survival was also similar (54% vs 60%).
