Abstract: Objective

To investigate the effect of neutrophil/lymphocyte ratio (NLR) in judgement of progrosis in the patients with non-small cell lung cancer(NSCLC) after treated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), and to provide the evidence-based medical basis for the prognosis judgement of NSCLC patients.

Methods

PubMed, Cochrane Library, EMBASE, Web of Science and China National Knowledge Internet(CNKI) databases were searched for collecting the studies about the relationship between NLR and the prognosis of NSCLC patients treated with EGFR-TKIs. Meta-analysis was conducted on the literatures that met the inclusion criteria.

Results

Eight studies contained 1 451 NSCLC patients were eventually included in the Meta-analysis. The progression-free survival(PFS)[hazard ratio(HR)=1.75, 95% confidence interval(95%CI):1.24-2.48, Z=3.17, P=0.002] and overall survival(OS)(HR=1.87, 95%CI:1.21-2.88, Z=2.84, P=0.005) of the NSCLC patients in high NLR group were significantly lower than those in low NLR group. The subgroup analysis results showed that after grouping by the ethnicity and NLR cutoff value, the PFS of NSCLC patients in the Asian(HR=1.70, 95%CI:1.14-2.53, Z=2.62, P=0.009), the non-Asian(HR=2.00, 95%CI:1.27-3.15, Z=3.00, P=0.003) and the NLR cutoff value≥3.5(HR=2.21, 95%CI:1.54-3.17, Z=4.29, P<0.001) in high NLR group were significantly low than those in low NLR group.The sensitivity analysis results showed that 8 included studies were stable and reliable.

Conclusion

In the NSCLC patients after treated with EGFR-TKIs, the high level of NLR is associated with the poor prognosis of NSCLC patients.
