Association of the neutrophil to lymphocyte ratio and clinical outcomes in patients with lung cancer receiving immunotherapy: a meta-analysis.

ABSTRACT:

Objectives

To explore the relationship between the pretreatment or post-treatment neutrophil to lymphocyte ratio (NLR) and overall survival (OS)/progression-free survival (PFS) in patients with lung cancer receiving immunotherapy.

Design

We searched several databases to collect relevant studies conducted until July 2019. We carefully reviewed the full text of the included publications and combined the HRs and 95% CIs to assess the association between the NLR and survival time in patients with lung cancer receiving immunotherapy.

Data sources

PubMed, the Cochrane Library, Embase and Web of Science ELIGIBILITY CRITERIA: Studies reporting the prognostic value of the NLR in patients with lung cancer receiving immunotherapy were enrolled.
