Prognostic significance of neutrophil-to-lymphocyte ratio in cervical cancer: A systematic review and meta-analysis of observational studies.

ABSTRACT:

Background and aims

The prognostic role of neutrophil-to-lymphocyte ratio (NLR) in cervical cancer are controversial. We conducted this meta-analysis to obtain a more accurate assessment of prognostic significance of NLR in cervical cancer.

Results

A total of 9 studies, consisting of 2,804 patients, were selected in this meta-analysis. Our pooled results showed that high pre-treatment NLR level was significantly associated with poorer overall survival (HR: 1.88, 95% CI 1.30-2.73) and shorter progression free survival (HR 1.65, 95% CI 1.18-2.29). Additionally, increased NLR was also significantly correlated with tumor size (OR 2.05, 95% CI 1.14-3.65), advanced FIGO stage (OR 2.12, 95% CI1.28-3.49) and lymph node involvement (OR 2.24, 95% CI 1.65-3.04).
