BACKGROUND: Inflammatory biomarkers have recently attracted attention as valuable prognosticators and predictors of survival outcomes in many cancers. We describe a new pre-treatment biomarker, expressed as the eosinophil-lymphocytes ratio (ELR) and validate other biomarkers such as the level of circulating eosinophils, neutrophil-lymphocytes ratio (NLR), platelet-lymphocytes ratio (PLR) and systemic immune-inflammatory index (SII) as prognostic factors in cervical cancer (CC) patients.
METHODS: A retrospective cohort of 151 consecutive patients diagnosed with CC and treated according to the European guidelines with radiotherapy and/or chemotherapy and/or surgery in our institution from 2009 to 2016 were evaluated. Patients were categorized into two different groups based on the optimal cut-off for each biomarker, according to the receiver operating characteristic (ROC) curves. Impact of blood biomarkers on overall survival (OS), cancer-specific survival (CCS) and progression-free survival (PFS) were examined.
RESULTS: Higher values of ELR, eosinophils and age ≥ 50 years were associated with better OS in univariate Cox analysis, while high NLR, PLR, SII, neutrophils ≥ 7.0, Bulky tumor and FIGO stage III-IV at diagnosis were prognosticators of worse survival outcomes. In multivariate analysis, the only factors independently impacting OS were ELR ≥ 0.07 (HR = 0.49, p = 0.048) and FIGO stage III-IV (HR = 2.5, p = 0.018). High PLR and SII were associated with shorter PFR.
CONCLUSIONS: Increased values of ELR and eosinophils portend better OS in CC. To our best knowledge, this is the first report describing eosinophils-related biomarker as an independent prognostic factor in CC.
