Objective To obtain a more accurate assessment of prognostic significance of NLR in ovarian cancer. Methods A systematic literature search was conducted using the electronic databases PubMed ,Web of Science,and Embase up to May 2016. Hazard ratio(HR)and odds ratio(OR)with 95% confidence interval (95%CI)were calculated. Statistical analysis was performed using Stata 12.0. Results 12 studies,consisting of 3 ,854 patients ,were selected in this meta-analysis. High NLR level was significantly associated with poorer overall survival(OS)(HR:1.69)and shorter progression free survival(PFS)(HR 1.63). Additionally,increased NLR was significantly correlated with advanced FIGO stage(OR 2.32),higher level of CA-125(OR 3.33),more extensive ascites(OR 3.54)as well as less chemotheraputic response(OR 0.53). Conclusions Elevated pretreat-ment NLR can serve as a predicative factor of poor prognosis for ovarian cancer.
