Prognostic relevance of regional lymph-node distribution in patients with N1-positive non-small cell lung cancer: A retrospective single-center analysis

Lung cancer is one of the leading causes of death worldwide [1]. Approximately 80% of lung cancer patients are consistent with non-small cell histology (NSCLC) [2]. The Tumor-Node-Metastasis (TNM) system is used to classify and stratify patients by prognosis according to tumor size (T), lymph node (LN) involvement (N) and presence of distant metastases (M). Its actual valid 8th edition was implemented in 2016 using clinical information from 70,976 consecutive NSCLC patients treated between 1999 and 2010 in 16 countries [3].
