Oncologic outcomes of segmentectomy compared with lobectomy for clinical stage IA lung adenocarcinoma: Propensity score–matched analysis in a multicenter study

Both overall outcomes and propensity score matched outcomes were compared in patients undergoing either lobectomy or segmentectomy for clinical stage IA adenocarcinoma of the lung.  In the overall cohort, 3-year recurrence-free and overall survival were similar between the groups.  Among the matched patients, RFS (92.9% vs 90.9%) and OS (93.2% vs 95.7%) were also similar between the lobectomy and segementectomy groups at 3 years.
