AbstractThis study aimed to analyze the predictive value of the neutrophil-to-lymphocyte ratio (NLR) to better clarify which patients with advanced non-small cell lung cancer (NSCLC) would benefit most from apatinib after multiline treatment for drug resistance. This observational cohort study involved patients with advanced NSCLC who were treated with apatinib between May 2016 to May 2018. The participants in this study had previously been treated with at least two treatment regimens. Multivariate logistic regression and Cox proportional risk models were used to evaluate the overall survival (OS) and progression-free survival (PFS) of the pretreatment NLR. A total of 125 patients were reviewed. The median age was 64 years (range, 33-92); and 32.8% of the patients were female. Only 0.8% of the patients had an Eastern Cooperative Oncology Group Performance Status (ECOG-PS) score ≥ 2. In multivariate analysis, pretreatment NLR ≥ 5 had an independent correlation with inferior OS (median 2.07 vs 3.40 months; HR 1.493, 95% CI 1.022-2.182; P = .038) and inferior PFS (median 1.83 vs 2.76 months; HR 1.478, 95% CI 1.015-2.153; P = .042). Elevated pretreatment NLR is associated with shorter OS and PFS in patients with advanced NSCLC treated with apatinib after multiline treatment for drug resistance.Copyright © 2022 the Author(s).
