Sublobar resection is increasingly being utilized for early-stage lung cancers, but optimal management when final pathology shows unsuspected mediastinal nodal disease is unclear. This study tested the hypothesis that lobectomy has improved survival compared to sublobar resection for clinical stage IA tumors with occult N2 disease.The use of sublobar resection and lobectomy for patients in the National Cancer Database who underwent primary surgical resection for clinical stage IA non-small cell lung cancer with pathologic N2 disease between 2010 and 2017 was evaluated using logistic regression. Survival was assessed with Kaplan-Meier analysis, log-rank test, and Cox proportional hazards model.A total of 2,419 patients comprised the study cohort, including 320 sublobar resections (13.2%) and 2,099 lobectomies (86.8%). Older age, female sex, smaller tumour size, and treatment at an academic facility predicted the use of sublobar resection. Patients undergoing lobectomy had larger tumors (2.40 vs 2.05?cm, p?
