Purpose. We aimed to determine the predictive value of several hematological markers of inflammation on the presence/absence of cervical cancer and also to determine their ability in discriminating precancerous cervical pathologies from cervical cancer. Materials and Methods. In this study, patients who presented to Acibadem Kayseri Hospital between May 2010 and June 2018 were evaluated. Forty patients with low-grade squamous intraepithelial lesions (LSIL), 40 patients with high-grade squamous intraepithelial lesions (HSIL), and 30 patients with cervical cancer (CC) were retrospectively included in this study. A control group of 70 healthy volunteers with normal cervical cytology was also included in the study. Results. The neutrophil-to-lymphocyte ratio (NLR) was significantly higher in patients with CC than in controls. The platelet-to-lymphocyte ratio (PLR) was significantly higher in patients with CC compared to those with LSIL and HSIL diagnoses and also controls (p<0.001). Logistic regression analysis revealed that age (OR: 1.075, 95\% CI: 1.020-1.132, p=0.007), NLR (OR: 1.643, 95\% CI: 1.009-3.142, p=0.047), and PLR (OR: 1.032, 95\% CI: 1.003-1.062, p=0.029) were predictors for the presence of CC. ROC curve analysis revealed that both NLR and PLR were predictive of CC with a cutoff value of 2.02 for NLR (71\% sensitivity and 60\% specificity, AUC: 0.682, p=0.004) and 126.7 for PLR (83\% sensitivity and 69\% specificity, AUC: 0.752, p<0.001). Conclusion. In addition to patients' age, determination of NLR and PLR values, which are simple, inexpensive, and readily available markers of systemic inflammation, may help in decision making precancerous pathologies of the cervix.
