Association between number of dissected lymph nodes and survival in stage IA non-small cell lung cancer: a propensity score matching analysis

Abstract

The NLNs was a protective prognostic factor in NSCLC patients with tumor size ≤ 2 cm. We demonstrated that patients with > 5 NLNs in the cohort of wedge resection, segmental resection, or lobectomy exhibited a significantly better OS.
