Abstract

Inflammation and tumor immunology are associated with prognosis in a variety of cancers. The aim of the present retrospective study was to identify associations between the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), cancer antigen 125 (CA125) concentrations, tumor response, performance status (PS) and survival of patients that developed recurrent ovarian cancer subsequent to receiving chemotherapy. The NLR and PLR measured prior to fourth‑line chemotherapy were significantly increased compared with those measured prior to second‑line chemotherapy (P=0.029 and 0.049, respectively). By using receiver operating characteristic curves, the cut‑off values were determined for the NLR, PLR and CA125 levels that were measured during the pre‑treatment phase, which predicted the outcomes. According to univariate analyses, pre‑treatment NLR >3.91, PLR >299.0 and PS 2 were each significantly associated with poor outcomes (P=0.001, 0.005 and 0.021, respectively). According to multivariate analyses, only pre‑treatment NLR was associated with poor outcome (P=0.035). The present findings indicate that pre‑treatment NLR is an important predictor of prognosis in patients with ovarian cancer that experience recurrence following chemotherapy.
