Background and Aims: Published data on the prognostic role of neutrophil-to-lymphocyte ratio (NLR) in ovarian cancer are controversial. We conducted this meta-analysis to obtain a more accurate assessment of prognostic significance of NLR in ovarian cancer. Materials and Methods: We conducted a systematic literature search using the electronic databases PubMed, Web of Science, and Embase up to May 2016. Hazard ratio (HR) and odd ratio (OR) with 95% confidence interval (95% CI) were calculated. Subgroup analyses were carried out to explore the source of heterogeneity. Statistical analysis was performed using Stata 10.0. Results: A total of 12 studies, consisting of 3,854 patients, which met our criterion were selected in this meta-analysis. Our pooled results showed that high pre-treatment NLR level was significantly associated with poorer overall survival (OS) (HR: 1.69, 95% CI 1.29-2.22) and shorter progression free survival (PFS) (HR 1.63, 95% CI 1.27–2.09). Additionally, increased NLR was also significantly correlated with advanced FIGO stage (OR 2.32, 95% CI1.79-3.00), higher serum level of CA-125 (OR 3.33, 95% CI 2.43-4.58), more extensive ascites (OR 3.54, 95% CI 2.31-5.42) as well as less chemotheraputic response (OR 0.53, 95% CI 0.40-0.70). The findings from most of subgroup meta-analyses were consistent with those from the overall meta-analyses. Conclusions: Elevated pre-treatment NLR could served as a predicative factor of poor prognosis for ovarian cancer patients.

Background and Aims. Plenty of studies were conducted to explore the prognostic significance of neutrophil-to-lymphocyte ratio (NLR) in ovarian cancer with contradictory results. This study aims to summarize the prognostic significance of NLR in patients with ovarian cancer. Methods. A literature search in PubMed, Cochrane Library, and Embase was conducted. The endpoints were progression-free survival (PFS) and overall survival (OS). Results. Eleven studies involving a total of 2,892 patients were identified. The results indicated that patients with high NLR had shorter PFS compared to patients with low NLR in ovarian cancer (HR = 1.55, 95% CI = 1.15–2.08, p=0.004, and I2=61%). Similarly, high NLR was related to shorter OS (HR = 1.51, 95% CI = 1.03–2.23, p=0.04, and I2=85%). Moreover, high NLR was significantly associated with shorter PFS when the NLR cut-off was less than 3.3 (p=0.03) or when treatment is operation (p=0.002). In addition, high NLR was distinctly related to worse OS in Asian people (p = 0.04) or operation (p = 0.04). Conclusion. High NLR was associated with shorter PFS and shorter OS in ovarian cancer. NLR is potentially a promising prognostic biomarker in patients with ovarian cancer.

BackgroundMeningiomas are the most common benign intracranial tumors. However, even WHO grade I meningiomas occasionally show local tumor recurrence. Prognostic factors for meningiomas have not been fully established. Neutrophil-to-lymphocyte ratio (NLR) has been reported as a prognostic factor for several solid tumors. The prognostic value of NLR in meningiomas has been analyzed in few studies.Materials and MethodsThis retrospective study included 160 patients who underwent surgery for meningiomas between October 2010 and September 2017. We analyzed the associations between patients’ clinical data (sex, age, primary/recurrent, WHO grade, extent of removal, tumor location, peritumoral brain edema, and preoperative laboratory data) and clinical outcomes, including recurrence and progression-free survival (PFS).ResultsForty-four meningiomas recurred within the follow-up period of 3.8 years. WHO grade II, III, subtotal removal, history of recurrence, Ki-67 labeling index ≥3.0, and preoperative NLR value ≥2.6 were significantly associated with shorter PFS (P < 0.001, < 0.001, 0.002, < 0.001, and 0.015, respectively). Furthermore, NLR ≥ 2.6 was also significantly associated with shorter PFS in a subgroup analysis of WHO grade I meningiomas (P = 0.003). In univariate and multivariate analyses, NLR ≥2.6 remained as a significant predictive factor for shorter PFS in patients with meningioma (P = 0.014).ConclusionsNLR may be a cost-effective and novel preoperatively usable biomarker in patients with meningiomas.

Purpose. The prognostic value of a new scoring system, termed F-NLR, that combines pretreatment fibrinogen level with neutrophil-lymphocyte ratio has been evaluated in various cancers. However, the results are controversial. The purpose of this study was to comprehensively analyze the prognostic value of F-NLR score in patients with cancers. Methods. An integrated search of relevant studies was conducted by screening the PubMed and Embase databases. Pooled hazard ratios, with 95% confidence intervals (CIs), for overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS) were calculated to estimate the prognostic significance of F-NLR score in patients with various tumors. A random effects model was used for comprehensive analysis, and subgroup and meta-regression analyses were used to explore sources of heterogeneity. Results. Thirteen articles reporting data from of 4747 patients were included in the study. Pooled analysis revealed that high F-NLR score was significantly associated with poor OS ( HR = 1.77 ; 95% CI, 1.51–2.08) and poor DFS/PFS ( HR = 1.63 ; 95% CI, 1.30–2.05). Subgroup and meta-regression analyses did not alter the prognostic role of F-NLR score in OS and DFS/PFS. Conclusions. Increased F-NLR score is significantly associated with poor prognosis in patients with cancers and can serve as an effective prognostic indicator.

Objectives: Many studies have examined the prognostic significance of the neutrophil-to-lymphocyte ratio (NLR) in oral cancer; however, the results are contradictory. We, therefore, conducted a meta-analysis aiming to clarify the prognostic value of the NLR in oral cancer patients. Methods: A literature search was conducted in the PubMed, Web of Science, and Embase databases. Stata version 12.0 was used for statistical analysis. Results: A total of 14 studies with 3216 patients were finally included. The results indicated that a high NLR was significantly associated with worse DFS (n=10, HR = 1.73, 95% confidence interval [CI] = 1.44–2.07, P<0.001). Similar results were observed for overall survival (OS) (n=9, HR = 1.61, 95% CI = 1.39–1.86, P<0.001). Moreover, a high NLR was also correlated with lymph node metastasis (n=7, odds ratio [OR] = 1.62, 95% CI = 1.32–1.98, P<0.001), advanced tumor stage (n=7, OR = 2.63, 95% CI = 2.12–3.25, P<0.001), T stage (n=6, OR = 3.22, 95% CI = 2.59–4.01, P<0.001), tumor differentiation (n=5, OR = 1.48, 95% CI = 1.03–2.11, P=0.033), and perineural invasion (n=4, OR = 1.83, 95% CI = 1.4–2.39, P<0.001). However, an elevated NLR was not correlated with gender. Conclusion: This meta-analysis showed that the NLR might be a potential independent prognostic factor in patients with oral cancer.

Abstract BackgroundThe main aim of this study was to validate the potential association between the preoperative prognostic nutritional index (PNI) and survival of patients with ovarian cancer (OC).MethodsWe systematically searched multiple databases (PubMed, EMBASE, and Web of Science) for publications up to June 30, 2019, to identify observational studies evaluating the PNI in relation to survival. Two reviewers independently extracted data and assessed the quality of each study using the Newcastle-Ottawa Scale (NOS). Summary hazard ratios (HR) and 95% confidence intervals (CI) were calculated with the aid of a random-effects model. The potential for publication bias was explored using Funnel plots as well as Begg’s and Egger’s tests.ResultsAmong the 15,000 studies selected for selection, 5 retrospective cohort studies (4 from China and one from Japan) comprising 1964 OC patients met the inclusion criteria. All studies were graded as ‘low risk of bias’ according to NOS. A low preoperative PNI was associated with poor overall survival (HR = 1.69, 95% CI = 1.16–2.46; I2 = 83.8%) and progression-free survival (HR = 1.86, 95% CI = 1.39–2.51; I2 = 29.7%) of OC patients. No significant publication bias was detected.ConclusionsCollective data from the present systematic review and meta-analysis suggest that a low preoperative PNI is associated with poor survival in OC. Further prospective studies are required to confirm these findings.
