Survival analysis highlights key prognostic factors in N1 lymph node-involved NSCLC patients, suggesting critical determinants for treatment.

Histological subtype significantly affects survival in patients with non-small cell lung cancer and N1 involvement.
Overall mean survival was 59.7 months with disease-free survival of 52.0 months in the analyzed cohort.
Cox regression analysis identified independent prognostic factors as histological subtype and visibility of N1 metastasis.
Central tumor location and visceral pleural invasion were significantly associated with survival outcomes, indicating their importance.

Karcı et al. (2025) studied this question.
