Prognostic Value of Lymphocyte-to-Monocyte Ratio (LMR) in Patients With Prostate Cancer: A Systematic Review and Meta-Analysis.

ABSTRACT: The objective of this study is to evaluate the prognostic value of lymphocyte-to-monocyte ratio (LMR) in patients with prostate cancer (PCa) by a method of meta-analysis. China National Knowledge Infrastructure (CNKI), Wanfang Data, PubMed, Web of Science, Cochrane Library, and Embase were searched to collect relevant literature until March 2023. The Newcastle-Ottawa Scale was used to assess the bias risk of the literature included. Hazard ratios (HRs) and 95% confidence intervals (CIs) were used to evaluate the prognostic value of LMR in PCa. Stata 15.0 statistical software was used for data analysis. A total of six published articles were included in this meta-analysis, containing 1,104 patients with PCa. The results of the meta-analysis indicated better overall survival (OS; HR = 1.73, 95% CI: 1.73, p = .001) and progression-free survival (PFS; HR = 2.63, 95% CI: 1.58~4.38, p < .001) in patients with PCa with low LMR compared with high LMR. In conclusion, compared with low LMR, PCa patients with high LMR have a better prognosis. LMR is an independent risk factor affecting the long-term prognosis of patients with PCa. The detection of LMR before treatment is of certain significance in judging the clinical prognosis of patients with PCa.

Project description:ObjectivesTo report the largest systematic review and meta-analysis to evaluate prognostic value of lymphocyte to monocyte ratio (LMR) in patients with esophageal cancer.MethodsWe conducted a systematic literature retrieval via PubMed, Embase, Web of Science, and Cochrane until December, 2023 for studies which evaluated the prognostic value of LMR in patients with esophageal cancer. Outcomes measured were overall survival (OS), disease-free survival (DFS), relapse-free survival (RFS), and progression-free survival (PFS).Results11 studies including 3,377 patients with esophageal cancer were included for meta-analysis. Meta-analysis demonstrated that OS (HR: 1.65; 95% CI: 1.19, 2.31; P = 0.003) and DFS (HR: 1.48; 95% CI: 1.09, 2.01; P = 0.01) were significantly shorter in the low LMR group compared with the high LMR group. In addition, meta-analysis revealed a similar PFS (HR: 1.58; 95% CI: 1.00, 2.51; P = 0.05) and RFS (HR: 1.17; 95% CI: 0.93, 1.46; P = 0.18) in the two groups. Subgroup analysis found that the predictive value of LMR for OS remained significant in resectable and unresectable esophageal cancers, and in studies with follow-up ≥24 months and < 24 months. Subgroup analysis based on treatment methods found that the prognostic value of LMR was significant for both patients who received PD-1/PD-L1 inhibitors and those who did not receive PD-1/PD-L1 inhibitors. However, subgroup analysis based on LMR threshold found that the significance remained in studies with LMR threshold<3.5 (HR: 2.09; 95% CI: 1.13, 3.87; P = 0.02) but disappeared in studies with LMR threshold ≥ 3.5 (HR: 1.39; 95% CI: 0.93, 2.07; P = 0.11).ConclusionsLow LMR is associated with poor prognosis in patients with esophageal cancer. Due to the simple availability and low cost of routine blood tests in clinical practice, LMR can be widely used to assess prognosis and construct risk prediction models for patients with esophageal cancer.Systematic review registrationPROSPERO, identifier CRD42024509796.

Project description:BackgroundPrognoses of most adult Hodgkin lymphoma (HL) patients are excellent; most of them can achieve permanent remission that can be considered cured. However, many are under-treated or over-treated by standard modern therapies. An accurate determination of prognosis may allow clinicians to design personalised treatment according to individual risk of disease progression and survival. Lymphocyte monocyte ratio (LMR) at diagnosis has been investigated as a prognostic biomarker in patients with HL. Our objective with this meta-analysis was to explore the prognostic value of the LMR at diagnosis in adult HL, by investigating the association between LMR and survival outcomes.MethodsPUBMED and EMBASE were searched for relevant articles. Survival outcomes that we investigated included overall survival (OS), progression-free survival (PFS), event-free survival (EFS), lymphoma-specific survival (LSS), and time to progression (TTP). No restriction to the language, date, study country, or sample size was applied. Final search of databases was performed on 2 April 2018. We performed random-effects meta-analysis to aggregate and summarise the results from included studies, where four or more studies on a particular outcome were available.ResultsA total of eight studies (all retrospective cohort studies) involving 3319 HL patients were selected for analysis. All studies except one reported the effect of LMR on OS; five reported on PFS, three reported on TTP and LSS, respectively, and one reported on EFS. The pooled estimates showed low LMR was associated with poor OS (hazard ratio [HR] 2.67, 95% CI 1.67, 4.26) and PFS (HR 2.19, 95% CI 1.46, 3.29). Subgroup analyses of OS stratified by LMR cut-off values and sample sizes both indicated that low baseline LMR was associated with poorer prognosis.ConclusionsLow LMR at diagnosis was associated with poor OS and PFS in HL. LMR is easy and cheap to determine and has a potential role in daily clinical management. More studies are needed to validate this biomarker and explore its interaction with known prognostic factors.

Project description:AimNeutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), or monocyte-lymphocyte ratio (MLR) has been shown to be related to the poor prognosis of cervical cancer, ovarian cancer, breast cancer, and other malignant tumors, but their role in predicting the prognosis of endometrial cancer is still controversial. Therefore, we conducted this meta-analysis to evaluate the effectiveness of NLR more accurately, PLR, or MLR in predicting the prognosis of endometrial cancer (EC).MethodsThis review systematically searched for relevant publications in databases of the Cochrane Library, PubMed, EMBASE, CNKI, WanFang, VIP, and CBM. Pooled hazard ratios (HR) with 95% confidence intervals (95% CI) were determined and used to explore the association between inflammatory biomarkers (NLR, PLR, and MLR) and overall survival (OS), progression-free survival (PFS), and disease-free survival (DFS) in a random-effects model. We also conducted subgroup analysis and publication bias in this meta-analysis. Stata 12.0 was used for statistical analysis.ResultsThis meta-analysis contained 14 eligible studies including 5,274 patients. Our results showed that NLR or PLR was associated with OS [NLR: HR, 2.51; 95% CI, 1.70-3.71; p <0.001 in univariate analysis (Ua); HR, 1.87; 95% CI, 1.34-2.60; p <0.001 in multivariate analysis (Ma); PLR: HR, 2.50; 95% CI, 1.82-3.43; p <0.001 in Ua; HR, 1.86; 95% CI, 1.22-2.83; p = 0.004 in Ma], but MLR was not associated with OS (HR, 1.44; 95% CI, 0.70-2.95; p = 0.325 in Ua; HR, 1.01; 95% CI, 0.39-2.60; p =0.987 in Ma). A further subgroup analysis found that the correlations were not affected by race, cutoff value, sample size, or treatment. Our meta-analysis showed that NLR or PLR was associated with DFS (NLR: HR, 2.50; 95% CI, 1.38-4.56; p =0.003 in Ua; HR, 2.06; 95% CI, 1.26-3.37, P =0.004 in Ma; PLR: HR, 1.91; 95% CI, 1.30-2.81; p = 0.001 in Ua), and NLR was associated with PFS only in the univariate analysis (HR, 1.71; 95% CI, 1.04-2.81; p =0.035 in Ua; HR, 1.79; 95% CI, 0.65-4.89; P =0.257 in Ma), but MLR was not associated with DFS (HR, 0.36; 95% CI, 0.03-4.13; p =0.409 in Ua).ConclusionsOur results indicated that pretreatment NLR and PLR were biomarkers of poor prognosis in patients with endometrial cancer. The results indicated that NLR or PLR was associated with OS and disease-free survival DFS, and NLR was associated with PFS only in univariate analysis, but MLR was not associated with OS or DFS.

Project description:Background: Stroke has become a major problem around the world, which is one of the main causes of long-term disability. Therefore, it is important to seek a biomarker to predict the prognosis of patients with stroke. This meta-analysis aims to clarify the relationship between the neutrophil-to-lymphocyte ratio (NLR) and the prognosis of stroke patients. Methods: This study was pre-registered in PROSPERO (CRD42020186544). We performed systematic research in PubMed, Web of Science, and EMBASE databases for studies investigating the prognostic value of NLR. Based on the enrolled studies, patients were divided into the low-NLR cohort and the high-NLR cohort. Odds ratios (ORs) with 95% confidence intervals (CIs) were extracted and analyzed by the Review Manager 5.3 and Stata 12.0 software. Heterogeneity was estimated by using Cochran's Q test and I 2 value. Sensitivity analyses and subgroup analyses were also performed to explore the potential sources of heterogeneity. Publication bias was assessed with funnel plots and assessed by Egger's tests. Results: Forty-one studies with 27,124 patients were included. In the overall analysis, elevated NLR was associated with an increased mortality in acute ischemic stroke (AIS) patients (OR = 1.12, 95% CI = 1.07-1.16) and in acute hemorrhagic stroke (AHS) patients (OR = 1.23, 95% CI = 1.09-1.39), poorer outcomes in AIS patients (OR = 1.29, 95% CI = 1.16-1.44), and in AHS patients (OR = 1.11, 95% CI = 1.03-1.20). While in terms of hemorrhagic transformation (HT), elevated NLR was associated with an increased incidence of HT in AIS patients (OR = 1.15, 95% CI = 1.08-1.23). Conclusions: This study demonstrated that elevated NLR was significantly associated with poor prognosis of stroke patients. High NLR is associated with a 1.1- to 1.3-fold increased risk of poor outcomes of AIS/AHS patients. NLR could be helpful as a potential prognostic biomarker to guide clinical decision making.
