Station 3A lymph node dissection does not improve long-term survival in right-side operable non-small-cell lung cancer patients: A propensity score matching study.

ABSTRACT:

Background

To investigate the impact of station 3A lymph node dissection (LND) on overall survival (OS) and disease-free survival (DFS) in completely resected right-side non-small-cell lung cancer (NSCLC) patients.

Methods

A total of 1661 cases with completely resected right-side NSCLC were included. Propensity score matching (PSM) was performed to minimize selection bias, and a logistic regression model was conducted to investigate the risk factors associated with station 3A lymph node metastasis (LNM). The Kaplan-Meier method and Cox proportional hazards model were used to evaluate the impact of station 3A LND on survival.

Results

For the entire cohort, 503 patients (30.3%) underwent station 3A LND. Of those, 11.3% (57/503) presented station 3A LNM. Univariate and m
