The role of inflammation biomarkers in differential diagnosis of pelvic tumours of ovarian origin: a single-centre observational study

Aim of the study Our aim was to analyse the feasibility of white blood cell and platelet counts along with their ratios as a prognostic factor in patients who underwent surgery for ovarian mass. Material and methods We retrospectively studied the patients admitted in the Department of Gynaecology due to adnexal mass. The potential association of the neutrophil-to-lymphocyte-ratio (NLR), neutrophil-to-monocyte (NMR), platelet-to-lymphocyte (PLR), lymphocyte-to-monocyte (LMR), monocyte-to-platelet, and malignancy was evaluated. Results Patients with malignant tumours were found with significantly higher ratios of NLR (p < 0.001) and PLR (p < 0.001) and lower LMR ratio (p < 0.001) compared to those with benign tumours. Furthermore, higher lymphocyte count (p = 0.04) and platelet count (p = 0.004) were found in cancer patients when compared with borderline tumours. No significant variations were detected regarding white blood cell count (p = 0.238), NMR ratio (p = 0.28), platelet-to-neutrophil ratio (p = 0.12), and platelet-to-monocyte ratio (p = 0.34). Conclusions Inflammation biomarker ratios can easily and inexpensive assist in distinguishing malignant ovarian tumours from benign ones.
