Predictive value of systematic inflammatory response biomarkers (NLR, LMR, PLR) in patients with ovarian cancer.

Introduction: The aim of the study was to assess the prognostic value of indicators calculated on the basis of initial hematology test results of neutrophil, lymphocyte, monocyte and platelet counts (NLR – neutrophil-to-lymphocyte ratio, LMR – lymphocyte-to-monocyte ratio, PLR – platelet-to-lymphocyte ratio) in patients with ovarian cancer and their compliance with the overall response to treatment. Materials and methods: Hematological tests were performed before first course of first-line chemotherapy in 145 patients with ovarian cancer. Response to treatment was assessed according to the RECIST1.1 criteria in all patients. Results: After the completion of first-line treatment, 70 (48.3%) patients had a complete response (CR) to the therapy. In this group, progression of disease occurred in 22 (31.4%) patients during 12 months of follow-up. In the CR group with progression, 17 (77.2%) presented high NLR and PLR levels. Among 48 (68.6%) patients with CR without progression after 12 months of follow-up, high levels of NLR and PLR were observed in 21 (43.8%) and 17 (35.4%) of them, respectively. Low LMRs were observed in 16 (72.7%) patients with progression and 16 (33.3%) without progression. Conclusion: High levels of NLR and PLR and low levels of LMR before treatment seems to predict 12-month disease progression in patients with complete response to first-line treatment.
