Sublobar resection is associated with less lymph nodes examined and lower delivery of adjuvant therapy in patients with 1.5-2.0 cm clinical IA2 non-small cell lung cancer. A retrospective cohort study.

Despite comparable overall survival to lobectomy, sublobar resection is associated with suboptimal lymphadenectomy in patients with 1.5-2.0cm NSCLC. Surgeons should be careful to perform adequate lymphadenectomy when performing sublobar resection to mitigate nodal under-staging and to identify appropriate patients for systemic therapy.
