Abstract:
Objective · To explored the correlation of preoperative peripheral blood neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) with clinical characteristics and prognosis of ovarian cancer. Methods · Patients' clinicopathological data of 127 cases of benign tumors and 286 cases of malignant tumor were collected, and the correlation between the level NLR and PLR in patients with ovarian cancer clinical pathology indicators and overall survival was analyzed. Results · preoperative NLR and PLR levels in patients with ovarian cancer were higher than those in benign tumors(P=0.000). The optimal cut-off point of NLR and PLR were 3.0 and 151. There was statistical significant difference between the high level of NLR group (NLR ≥ 3) and the low level of NLR group in pathological type, FIGO staging, lymph node metastasis, CA125 level and the amount of ascites (P<0.05). There was statistical significant difference between the high level of PLR group (PLR ≥ 151) and the low level of PLR group in FIGO stage,transfer status, CA125 level and quantity of ascites (P<0.05). The median survival time for NLR/PLR in the high level group were 33 and 33.5 months lower than that ofthe corresponding group of 44.5 and 49.5 months (P=0.044, P=0.000). Multivariate Cox regression analysis showed that PLR ≥ 151 were independent risk factors affectOS in ovarian cancer patients (HR=1.936, 95% CI=1.013-3.698, P=0.045). Conclusion · The elevated blood preoperative PLR indicates poor prognosis of ovarian cancer patients. Preoperative PLR may serve as an important independent prognostic factor for ovarian cancer patients.
