Objective: The purpose of this study was to investigate the prognostic impact of neutrophil to lymphocyte ratio (NLR), derived neutrophil to lymphocyte ratio (dNLR), platelet to lymphocyte ratio (PLR), and lymphocyte to monocyte ratio (LMR) on breast cancer given overall survival. Patients and Methods: We retrospectively evaluated patients diagnosed with primary breast cancer from 2004 to 2020. The association between NLR, dNLR, LMR, and PLR and overall survival (OS) was analyzed. Results: The one-year, three-year, five-year, and ten-year OS were 96%, 83%, 78%, 71%, and 63%, respectively. The parameters associated with patients with breast cancer included lymph node involvement, distant metastasis, and staging. We evaluated the baseline characteristics of the patients, according to the PLR, NLR, dNLR, and LMR, and found no significant differences. Conclusions: Serum inflammatory indicators such as neutrophil, lymphocyte, as well as NLR dNLR, LMR, and PLR, were shown to have no significant influence on prognosis in patients with breast cancer. Prospective research with a larger population of patients will provide more reliable results.

Abstract Background The pathophysiology of isolated coronary artery ectasia (CAE) with the coronary slow flow (CSF) phenomenon is still unclear. The purpose of this study was to investigate the risk factors for isolated CAE complicated with CSF. Methods A total of 126 patients with isolated CAE were selected retrospectively. The patients were grouped into the no CSF (NCSF) group (n = 55) and the CSF group (n = 71) according to the corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC). Data on demographics, laboratory measurements, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd), CTFC and diameters of three coronary arteries were collected. Results The proportions of males (84.5% vs. 61.8%, p = 0.004) and patients with a smoking history (63.4% vs. 43.6%, p = 0.021) were higher in the CSF group than in the NCSF group. The neutrophil-to-lymphocyte ratio (NLR) (2.08(1.68–3.21) vs. 1.89 ± 0.58, p = 0.001), mean diameter of coronary arteries (mean D) (5.50 ± 0.85 vs. 5.18 ± 0.91, p

Abstract Background We sought to compare the prognostic significance of different preoperative complete blood count cell ratios in patients with oral cavity squamous cell carcinoma (OSCC) treated with surgery and postoperative radiotherapy (PORT). Methods We retrospectively reviewed the clinical records of 890 patients with OSCC who were treated with surgery and PORT. The following preoperative complete blood count cell ratios were collected: neutrophil‐to‐lymphocyte ratio (NLR), platelet‐to‐lymphocyte ratio (PLR), and lymphocyte‐to‐monocyte ratio (LMR). Overall survival (OS), local control, regional control, and distant control (DC) served as the main outcomes of interest. Results The results of multivariate analysis in the entire study cohort revealed that a low NLR was the only independently favorable marker of both OS (adjusted hazard ratio [HR]: 0.794, 95% confidence interval (CI): 0.656–0.961, bootstrap p = 0.028) and DC (adjusted HR: 0.659, 95% CI: 0.478–0.909, bootstrap p = 0.015). Both LMR and PLR were not retained in the model as independent predictors. Subgroup analyses in high‐risk patients (i.e., those bearing T4 disease, N3 disease, or poor differentiation) revealed that a high NLR was a significant adverse risk factor for both OS and DC (all p

Abstract Background The aim of this study was to assess the effect of the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio on overall survival and disease-free survival in patients with lung cancer treated with radical surgery. Methods We performed a retrospective review of patients with lung cancer who prospectively underwent radical resection between 2004 and 2012. Blood samples were taken as part of the preoperative workup. The inflammatory markers studied were absolute values of lymphocytes, monocytes, neutrophils and platelets, with subsequent calculation of ratios. Median follow-up was 52 months. Results Two hundred and sixty-eight patients underwent surgery, of whom 218 (81.3%) were men. Mean age was 62.9 ± 8.7 years. A lymphocyte-to-monocyte ratio ≥ 2.5 was independently associated with longer disease-free survival (hazard ratio [HR] 0.476 (0.307–0.738), p = 0.001) and longer overall survival (HR, 0.546; 95% CI: 0.352–0.846; p = 0.007), in models adjusted for age, sex, stage, and type of resection. No other systemic inflammatory marker showed a significant association. Conclusion Preoperative LMR is an independent prognostic factor of overall survival and recurrence-free survival in patients with surgically-resected early stage lung cancer.

Here, we developed a prostate cancer (PCa) risk nomogram including lymphocyte-to-monocyte ratio (LMR) for initial prostate biopsy, and internal and external validation were further conducted. A prediction model was developed on a training set. Significant risk factors with P < 0.10 in multivariate logistic regression models were used to generate a nomogram. Discrimination, calibration, and clinical usefulness of the model were assessed using C-index, calibration plot, and decision curve analysis (DCA). The nomogram was re-examined with the internal and external validation set. A nomogram predicting PCa risk in patients with prostate-specific antigen (PSA) 4–10 ng ml−1 was also developed. The model displayed good discrimination with C-index of 0.830 (95% confidence interval [CI]: 0.812–0.852). High C-index of 0.864 (95% CI: 0.840–0.888) and 0.871 (95% CI: 0.861–0.881) was still reached in the internal and external validation sets, respectively. The nomogram exhibited better performance compared to the nomogram with PSA only (C-index: 0.763, 95% CI: 0.746–0.780, P < 0.001) and the nomogram with LMR excluded (C-index: 0.824, 95% CI: 0.804–0.844, P < 0.010). The calibration curve demonstrated good agreement in the internal and external validation sets. DCA showed that the nomogram was useful at the threshold probability of >4% and

Introduction: Lymphocyte‐to‐monocyte ratio (LMR) has been reported as a prognostic factor in many cancers but the data are to date limited for its use in oral cavity cancer. The purpose of this study was to evaluate the prognostic value of LMR in advanced‐stage oral cavity cancer. Methods: Data from 211 advanced‐stage oral cancer patients treated with curative intent between January 2009 and December 2015 were obtained from the hospital information system. Pretreatment LMR and other hematologic parameters were recorded and an LMR cutoff value was calculated. Overall survival between the groups above (high LMR) and below (low LMR) the cutoff was compared and hazard ratios from univariate and multivariate analyses using a Cox proportional hazards model calculated. Results: Overall survival and disease‐specific survival were better in the high LMR group. The 5‐year overall survival rates were 31.6% and 15% in the high LMR and low LMR groups, respectively. Multivariate analysis using a Cox proportional hazards model showed that treatment modality and LMR were the only factors associated with overall survival. Conclusion: Low LMR was associated with poor survival outcome in patients with advanced‐stage oral cavity cancer. Level of Evidence: 2b. [ABSTRACT FROM AUTHOR]

Simple Summary: This retrospective study using the prospectively collected registry data of newly diagnosed, previously untreated hepatocellular carcinoma (HCC) evaluates the significance of systemic inflammatory markers (SIMs) to intrahepatic recurrence (IHR) after curative treatment. Out of 4076 patients who met the inclusion criteria, 52.6% experienced IHR. SIMs, including pre-treatment platelet-to-lymphocyte ratio (PLR), post-treatment changes of neutrophil-to-lymphocyte ratio PLR, and lymphocyte-to-monocyte ratio were significantly associated with the prognosis of early-stage HCC patients who received initial curative treatment. The prognostic significances of SIMs were consistent for IHR-free survival, early and late IHR, and overall survival. Systemic inflammatory markers (SIMs) are known to be associated with carcinogenesis and prognosis of hepatocellular carcinoma (HCC). We evaluated the significance of SIMs in intrahepatic recurrence (IHR) of early-stage HCC after curative treatment. This study was performed using prospectively collected registry data of newly diagnosed, previously untreated HCC between 2005 and 2017 at a single institution. Inclusion criteria were patients with Barcelona Clinic Liver Cancer stage 0 or A, who underwent curative treatment. Pre-treatment and post-treatment values of platelet, neutrophil, lymphocyte, monocyte, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and lymphocyte/monocyte ratio (LMR) were analyzed with previously well-known risk factors of HCC to identify factors associated with IHR-free survival (IHRFS), early IHR, and late IHR. Of 4076 patients, 2142 patients (52.6%) experienced IHR, with early IHR in 1018 patients (25.0%) and late IHR in 1124 patients (27.6%). Pre-treatment platelet count and PLR and post-treatment worsening of NLR, PLR, and LMR were independently associated with IHRFS. Pre-treatment platelet count and post-treatment worsening of NLR, PLR, and LMR were significantly related to both early and late IHR. Pre-treatment values and post-treatment changes in SIMs were significant factors of IHR in early-stage HCC, independent of previously well-known risk factors of HCC. [ABSTRACT FROM AUTHOR]

Objectives: Our study was aimed to investigate the clinical characteristics of the patients with COVID-19 pneumonia and research new diagnostic methods for the disease. Methods: In this retrospective study, medical records of 46 novel coronavirus-infected pneumonia (NCIP) patients and 30 healthy individuals in the two multiple hospitals from January 2020 to March 2020 were studied. Clinical characteristics, chest computed tomographic (CT) scans, medicine treatment and laboratory information were collected and retrospectively analyzed. Neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR) and platelet-to-lymphocyte ratio (PLR) were evaluated. Results: The main symptoms of the patients with NCIP were fever (100%), cough (82.6%), anorexia (37%), expectoration (34.8%) and fatigue (21.7%), dyspnea (15.2%). Ground glass opacity (GGO) with patch shadow was the main observation of the CT imaging (43.4%), followed by GGO (21.7%), patch shadow (19.5%), GGO with consolidation (8.7%) and GGO with reticular pattern (2.1%). The median white blood cell (WBC) count, lymphocyte count, platelet, and lymphocyte-monocyte ratio (LMR) in NCIP group were all significantly lower than in control group (p<0.001, for all comparisons), while the median neutrophil-monocyte ratio (NLR) and platelets-monocyte ratio (PLR) were both significantly higher (p<0.001, for both comparisons). Median WBC count, lymphocyte count, and platelet count on discharge were significantly higher than on admission (p<0.05). Median PLR was significantly lower two weeks after discharge (p<0.001), while NLR remained the same. The area under the curve (AUC) value of WBC, lymphocyte and platelet counts, NLR, LMR and PLR were 0.766, 0.931, 0.655, 0.780, 0.847 and 0.845, respectively. Early stages of the disease were associated with quick changes in WBC, lymphocyte, and platelet levels. However, NLR did not recover even two weeks after the discharge. Conclusion: Changes in WBC, lymphocyte, and platelet counts, as well as NLR, LMR and PLR are strongly associated with COVID-19 pneumonia. Monitoring blood markers may assist in evaluating the progression of the disease [ABSTRACT FROM AUTHOR]

Background: Calcific aortic valve stenosis (CAVS) represents a serious health threat to elderly patients. Post-stenotic aortic dilation, a common feature in CAVS patients, might progress into aneurysm and even dissection, potential consequences of CAVS, and predicts a poor prognosis. This study sought to investigate the association of lymphocyte-to-monocyte ratio (LMR), an inflammatory biomarker, with severe post-stenotic aortic dilation in a case-control study in Chinese population.Materials and Methods: 208 consecutive patients with CAVS were recruited retrospectively in a case-control study in Chinese population, from July 1, 2015 to June 31, 2018. LMR was statistically analyzed using the ROC curve and binary logistic regression analyses for its prognostic value in severe post-stenotic aortic dilation.Results: LMR was significantly reduced in patients with severe post-stenotic aortic dilation (2.72 vs. 3.53, p = 0.002 < 0.05) compared to patients without severe post-stenotic aortic dilation. There was an inverse correlation observed between the maximal diameter of ascending aorta and LMR in the overall patients (r = - 0.217, p = 0.002 < 0.05). For post-stenotic aortic dilation, the prevalence of high-LMR group was statistically lower than that of low-LMR group (19.7% vs. 43.9%, p < 0.001). The maximal diameter of ascending aorta was significantly reduced in the high-LMR group (4.35 vs. 4.76, p = 0.003 < 0.05) compared to low-LMR group. Additionally, LMR was identified in the multivariate analysis independently associated with severe post-stenotic aortic dilation (AUC 0.743, 95% CI: [0.573-0.964], p = 0.025).Conclusions: This study provided the evidence of an inverse correlation between severe post-stenotic aortic dilation and LMR. LMR is potentially independently associated with severe post-stenotic aortic dilation. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to evaluate the utility of inflammation-based prognostic scores (IBPS) and systemic immune-inflammation index (SII) in the treatment of oral cancer patients.Methods: For the 183 patients enrolled in this study, IBPS and SII were calculated from peripheral blood samples obtained before and after treatment and at the time of relapse. We examined overall survival (OS) and disease-free survival (DFS) using previously reported cut-off values for IBPS. Cut-off values of neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio (PLR), and prognostic nutritional index (PNI) were analyzed as NLR 1.79, PLR 114.97, LMR 5, and PNI 52.44. The cut-off value for SII was set at 569. OS and DFS were analyzed by Kaplan-Meier methods using the cutoff of each IBPS and SII. Univariate analysis and multivariate analysis using Cox proportional hazards were performed for OS and DFS.Results: Kaplan-Meier methods showed the high-PNI group showed good prognosis including OS and DFS, while the high-SII group displayed poor DFS. Univariate analysis showed that pre-treatment high PNI and low SII were significantly associated with better prognosis. Multivariate analysis identified pre-treatment PNI as independently associated with OS. For DFS, univariate analysis using Cox proportional hazards modeling showed that pre-treatment high NLR and high SII were significantly associated with worse prognosis, while high PNI was significantly associated with better prognosis. Multivariate analysis identified pre-treatment PNI and SII as independently associated with DFS. Parameters of PNI and SII components were compared between pre-treatment, post-treatment and at relapse in the high- and low-PNI groups. PNI was predominantly decreased in both high- and low-PNI groups at post-treatment and at relapse compared to pre-treatment. This trend was also observed for albumin.Conclusions: Higher pre-treatment PNI was associated with better OS, while lower pre-treatment PNI and higher treatment SII were associated with poorer DFS in oral cancer patients. Our data indicated that PNI and SII might offer useful biomarkers for gauging prognosis and the efficacy of conventional therapies. [ABSTRACT FROM AUTHOR]

Summary: Background. Mucosal melanoma is rare and has distinct clinical and genetic features. Even with advances in targeted and immune therapies, the survival of patients with advanced or recurrent mucosal melanomas remains poor. The standard treatment remains controversial and we conducted this real-world study aimed to explore continuous intravenous recombinant human endostatin (Rh-endostatin) infusion plus chemotherapy in this population in the first-line setting. Methods. Overall, 43 patients with advanced or recurrent mucosal melanoma treated at Fudan University Shanghai Cancer Center between April 2017 and August 2020 were retrospectively included. Patients received dacarbazine plus cisplatin or temozolomide plus cisplatin per the investigators' preference. Rh-endostatin (105 mg/m2) was administered with continuous infusion for 168 h (Civ 168 h). Results. Of the 43 patients, 72.1% had metastatic disease, and the most common primary site was the gastrointestinal tract (51.2%). The most commonly observed mutations were NRAS (23.1%), BRAF (7.7%) and CKIT mutations (5.1%). An objective response was observed in 12 (30.0%) of the 40 evaluable patients, and disease control was achieved in 31 (77.5%) patients. With a median follow-up of 17.6 months, the median progression-free survival (PFS) and overall survival (OS) were 4.9 and 15.3 months, respectively. Additionally, high lymphocyte-to-monocyte ratio (LMR) (p = 0.023, HR 0.29, 95% CI: 0.10–0.84) and BRAF/KIT/RAS mutation (p = 0.028, HR 0.24, 95% CI: 0.07–0.86) were independently correlated with prolonged OS. Toxicity was manageable overall. Conclusion. Continuous Rh-endostatin infusion plus chemotherapy was effective and safe for the treatment of advanced or recurrent mucosal melanoma. High LMR was correlated with favorable PFS and OS in this patient population. [ABSTRACT FROM AUTHOR]

Background: Head and neck squamous cell carcinomas are associated with systemic inflammation (SI). We evaluated whether DNA methylation‐derived SI (mdSI) indices are associated with oropharyngeal cancer risk and survival. Methods: Ninety‐four oropharyngeal squamous cell carcinoma (OPSCC) cases and 57 controls with DNA methylation data were included. Logistic regression analysis and survival analysis were performed to test the association of mdSI indices with OPSCC risk and survival. Results: Higher methylation‐derived neutrophil‐to‐lymphocyte ratio (mdNLR) was associated with increased risk of OPSCC (OR = 1.21, 95%CI: 1.11–1.40) while no association was found with methylation‐derived lymphocyte‐to‐monocyte ratio (mdLMR). For 5‐year overall survival, higher mdLMR was significantly associated with decreased risk of death (HR = 0.25, 95%CI: 0.10–0.64) while the converse was observed for mdNLR (HR = 2.48, 95%CI: 1.04–5.92). Conclusion: We observed an association between mdSI indices and OPSCC risk and 5‐year overall survival. It is possible to use mdLMR as an independent prognostic factor for OPSCC.

Abstract Background Routine blood parameters, such as the lymphocyte (LYM) count, platelet (PLT) count, lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), lymphocytes multiplied by platelets (LYM*PLT) and mean platelet volume-to-platelet ratio (MPV/PLT), are widely used to predict the prognosis of infectious diseases. We aimed to explore the value of these parameters in the early identification of influenza virus infection in children. Methods We conducted a single-center, retrospective, observational study of fever with influenza-like symptoms in pediatric outpatients from different age groups and evaluated the predictive value of various routine blood parameters measured within 48 h of the onset of fever for influenza virus infection. Results The LYM count, PLT count, LMR and LYM*PLT were lower, and the NLR and MPV/PLT were higher in children with an influenza infection (PCR-confirmed and symptomatic). The LYM count, LMR and LYM*PLT in the influenza infection group were lower in the 1- to 6-year-old subgroup, and the LMR and LYM*PLT in the influenza infection group were lower in the > 6-year-old subgroup. In the 1- to 6-year-old subgroup, the cutoff value of the LMR for predicting influenza A virus infection was 3.75, the sensitivity was 81.87%, the specificity was 84.31%, and the area under the curve (AUC) was 0.886; the cutoff value of the LMR for predicting influenza B virus infection was 3.71, the sensitivity was 73.58%, the specificity was 84.31%, and the AUC was 0.843. In the > 6-year-old subgroup, the cutoff value of the LMR for predicting influenza A virus infection was 3.05, the sensitivity was 89.27%, the specificity was 89.61%, and the AUC was 0.949; the cutoff value of the LMR for predicting influenza B virus infection was 2.88, the sensitivity was 83.19%, the specificity was 92.21%, and the AUC was 0.924. Conclusions Routine blood tests are simple, inexpensive and easy to perform, and they are useful for the early identification of influenza virus infection in children. The LMR had the strongest predictive value for influenza virus infection in children older than 1 year, particularly in children older than 6 years with influenza A virus infection.

Abstract Aim The lymphocyte‐to‐monocyte ratio (LMR) is useful for predicting the prognosis of patients with gastric cancer (GC) and those with colorectal cancer (CRC) undergoing surgery. The relationship between the LMR and postoperative outcome of patients with early‐stage gastrointestinal cancers such as stage I GC and CRC remains unclear. Methods We retrospectively evaluated 323 stage I GC and 152 stage I CRC patients undergoing surgery. Univariate and multivariate analyses using the Cox proportional hazards model were performed to identify the clinical characteristics associated with overall survival (OS), and the cut‐off values of these variables were determined by receiver operating characteristic analysis. The Kaplan–Meier method and log‐rank test were used for postoperative survival comparisons according to the LMR (GC: LMR 75/≤75 years) (HR, 3.511; 95% CI, 1.881‐6.551; P 3.5 g/dL) (HR, 3.040; 95% CI, 1.575‐5.869; P = 0.001), in stage I GC patients. Survival analysis demonstrated a significantly poorer OS in stage I GC patients with a LMR

The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) were analyzed in various carcinomas and their potential prognostic significance was determined. The objective of present study was to determine the correlation between these parameters and the survival of patients with small cell lung cancer (SCLC), since very few studies have been published on this type of carcinoma.

INTRODUCTION: Although it is known that mean platelet volume (MPV), red blood cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) are predictive for arterial trombosis and adverse events, it is not clear whether they help in the diagnosis of deep vein thrombosis. The aim of the study was to evaluate it. For this purpose MPV, RDW, NLR and LMR were measured and compared between in patients with DVT and control groups. METHODS: In a retrospective study, a total of 144 subjects (77 patients with DVT, 67 control) were examined. Mean platelet volume, RDW, NLR and LMR were calculated and compared between the groups. It was investigated whether there was a correlation between D-dimer values and MPV, RDW, NLR, LMR. RESULTS: Mean platelet volume, RDW and NLR values were significantly higher in the patient group than in the control group (9.68+-1.89 vs. 8.9+-1.01, p=0.003, 12.77+-3.67 vs. 11.15+-2.16, p=0.002 and 1.91+-0.84 vs. 1.51+-0.54, p=0.001, respectively). On the other hand LMR was lower in the patient group (6.27+-3.14 vs. 8.85+-3.92, p

Abstract Background The association between the lymphocyte-to-monocyte ratio (LMR) and prognosis in the patients with acute coronary syndrome (ACS) is not fully understood. We performed this systematic review and meta-analysis to evaluate the correlation between LMR and mortality or major adverse cardiac events (MACE) in patients with ACS. Methods A systematic search was performed in PubMed, MEDLINE, EMBASE, the Cochrane Library, Scopus, and Web of science. The association between LMR and mortality/MACE was analyzed in patients with ACS. The search was updated to April 15, 2020. Results A total of 5 studies comprising 4343 patients were included in this meta-analysis. The results showed that lower LMR predicted higher short-term mortality/MACE (hazard ratio [HR] = 3.44, 95% confidence interval [CI]: 1.46–8.14, P

Abstract Background Prognostic biomarkers provide essential information about a patient’s overall outcome. However, existing biomarkers are limited in terms of either sample collection, such as requiring tissue specimens, or the process, such as prolonged time for analysis. In view of the need for convenient and non-invasive prognostic biomarkers for oral cancer, we aimed to investigate the prognostic values of neutrophil-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and platelet-to-lymphocyte ratio in patient survival. We also aimed to explore the associations of these ratios with the clinicopathologic characteristics of Japanese oral squamous cell carcinoma patients. Methods This study was a non-randomized retrospective cohort study in a tertiary referral center. We included 433 patients (246 men, 187 women) who underwent radical surgery for oral cancers between January 2001 and December 2013. We evaluated various risk factors for poor prognosis including neutrophil-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and platelet-to-lymphocyte ratio with univariate and multivariate analyses. The disease-specific survival and overall survival rates of patients were compared among the factors and biomarkers. Results In multivariable Cox proportional hazards analysis, high neutrophil-to-lymphocyte ratio (hazard ratio 2.87, 95% confidence interval 1.59–5.19, P

Objectives: Systemic inflammation markers have been demonstrated to be asso ciated with prognosis in various tumors. In this study, we aimed to assess the value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index and the counts of lymphocyte, monocyte and neutrophil in predicting prognosis among patients with resected pancreatic neuroendocrine neoplasms (pNENs). Methods: A total of 174 patients were included in the study. Univariate and multivariate analyses were performed to evaluate the predictive roles of infl ammation markers for relapse-free survival (RFS) and overall survival (OS) in pNEN patients. Results: The optimal cut-off values of NLR, LMR and lymphocyte count wer e 1.9, 5.0 and 1.4 × 109/L, respectively, determined by the X-tile software. RFS was found to be significantly longer in patients with NLR ≤1.9 (P = 0.041), LMR >5.0 (P < 0.001) and lymphocyte count >1.4 × 109/L (P = 0.002) in comparison to those with NLR >1.9, LMR ≤5.0 and lymphocyte count ≤1.4 × 109/L, respectively. Multivariate analysis revealed that LMR (hazard ratio 0.30, 95% CI 0.11–0.85, P = 0.023) was an independent predictor for RFS, but not NLR or lymphocyte count. For long-term survival analysis, patients with NLR ≤1.9 (P = 0.016) were found to be associated with favorable OS, but NLR was not an independent factor validated by multivariate analysis. Conclusions: Preoperative LMR is an independent systemic inflammation marker to predict relapses in pNEN patients who underwent curative resections, whose clinical value needs to be verified in further large sample-based prospective studies

Purpose: Inflammatory indexes, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII) and lymphocyte-to-monocyte ratio (LMR), have been confirmed as prognostic factors in multiple manigances. However, the prognostic value of these parameters in bevacizumab-treated non-small-cell lung cancer (NSCLC) is still not clear. Methods: We retrospectively studied 119 patients with advanced NSCLC who received bevacizumab treatment. The associations of pretreatment NLR, PLR, SII and LMR with progression-free survival (PFS) and overall survival (OS) were analyzed. Results & Conclusion: The median PFS and OS of patients with high baseline NLR, PLR and SII and low LMR were significantly decreased than those of patients with low baseline NLR, PLR and SII and high LMR. Multivariable analysis indicated that high baseline SII was independently related with inferior prognosis, and baseline LMR was an independent predictor for OS.

Objective Intravascular large B-cell lymphoma (IVLBCL) is a critical cause of fever of unknown origin (FUO). While a pathological analysis is essential for diagnosing IVLBCL, the indications for an invasive procedure may be ascertained using easy, non-invasive tests. The lymphocyte-to-monocyte ratio (LMR) can reportedly predict the diagnosis of malignant lymphoma in patients with lymphadenopathy; however, its clinical utility in predicting an IVLBCL diagnosis in patients with FUO remains to be elucidated. Methods The medical records of 91 patients with FUO who underwent a skin biopsy for suspected IVLBCL between January 2010 and April 2023 were retrospectively reviewed. Patients Seventeen and 60 patients with and without pathologically diagnosed IVLBCL, respectively, were included in the analysis. The laboratory data nearest to the timing of the skin biopsy were then compared between the groups. Results Among the variables with an intragroup difference, a low white blood cell (WBC) count and LMR were predictors of an IVLBCL diagnosis after adjusting for covariates. A receiver operating characteristic analysis demonstrated that a WBC ≤7,200 and LMR ≤3.0 predicted the diagnosis with a sensitivity of 88.2% and 100%, and a specificity of 65.0% and 43.3%, respectively. In addition, the probability of IVLBCL increased to 71.4% in patients with both variables but was 0% in those with neither variable, indicating its potential utility in determining the need for an invasive procedure. Conclusion The WBC count and LMR predicted an IVLBCL diagnosis in patients presenting with FUO.

Background: This study aimed to investigate whether there is a correlation between some serum inflammatory markers and the survival of patients with malignant pleural effusions (MPEs)., Methods: The prospective study included 125 patients (67 males, 58 females; median age: 62 years; range, 40 to 92 years) who underwent thoracentesis for pleural effusion between January 2020 and December 2021. An overall survival analysis was performed, and survival differences between the groups were investigated. The cutoff value of the inflammatory parameters associated with mortality was determined by receiver operating characteristic analysis., Results: Median survival after detection of MPE was six months, and three- and five-year overall survivals were 16% and 4%, respectively. There was a significant correlation between the ECOG (Eastern Cooperative Oncology Group) score of the patients and the median survival. Serum C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), fluid albumin, and serum lactate dehydrogenase (LDH)-to-pleural LDH ratio and survival had a statistically significant relationship in receiver operating characteristic analysis. Threshold values were determined accordingly. Poor prognostic factors that were found to be statistically significant were high CRP (p=0.001), high NLR (p=0.001), high PLR (p=0.02), and high serum LDH-to-pleural LDH ratio (p=0.04)., Conclusion: Some serum inflammatory markers, including high CRP, high NLR, high PLR, and high serum LDH-to-pleural LDH ratio, can be a simple and inexpensive method in predicting prognosis in patients with MPE., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2024, Turkish Society of Cardiovascular Surgery.)

The lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), platelet-to-neutrophil ratio (PNR), C-reactive protein (CRP)-to-lymphocyte ratio (CLR) and fibrinogen-to-albumin ratio (FAR) are well-known indicators of the systemic inflammatory response (SIR). Less is known about the association of SIR with the echocardiographic parameters and the histopathological (HP) aspects of the mitral valve in patients who have undergone cardiac surgery to repair or replace the mitral valve. Information on serum parameters, transesophageal echocardiography findings, and HP results was obtained from 166 patients who had undergone cardiac surgery to address mitral valve regurgitation. Among these patients, 30 were diagnosed with mitral valve prolapse, with 15 cases showing mitral valve flail or chordae rupture. The possible association between SIR, echocardiographic aspects of mitral valve flail and the HP aspect was checked. Fibrosis, hyalinization and myxoid degeneration of the valve were scored under microscope. Hyalinization of the mitral valve had a significant positive association with LMR and PLR (p=0.041 and p=0.03, respectively) and with NLR (p=0.093). A higher fibrosis degree was present in the valves without flail compared with those with flail (p=0.000). The monocyte average values of the group without flail were statistically significantly higher than those in the flail group (p=0.029). An increase of one unit in the value of monocytes was found to decrease the chances of flail [odds ratio (OR) 0.017, p=0.068, significant at p<0.1 level]. SIR parameters can be used to appraise inflammation status in mitral valve disease and to establish the risk of chordae rupture/flail in the case of mitral valve prolapse., Competing Interests: The authors declare no conflict of interests.

Introduction: Systemic inflammatory response (SIR) indicators are an emerging category of serum biomarkers with significant potential as prognostic and predictive factors in various types of cancers The primary focus of our study was to determine the prognostic value of the lymphocyte-to-monocyte ratio (LMR), platelet-to-albumin ratio (PLR) and platelet-to-albumin ratio (PAR) in evaluating the response to neoadjuvant treatment for patients with rectal cancer., Materials and Methods: We included 99 consecutive patients with rectal cancer which were admitted for surgery in our institution after completing a standard neoadjuvant radio-chemotherapy regimen. Several hematologic parameters, including LMR, PAR and PLR, were calculated by collecting and analyzing blood samples preoperatively. Cases were divided into groups using ROC curve analysis to determine optimal cutoff values for each of the investigated parameters. Treatment response was assessed through histopathological analysis of the resected specimens., Results: PLR values over 215.2 were correlated with the presence of lymph node metastasis. A similar correlation was observed between PAR values over 41.89 and lymph node positivity. A significant correlation was observed between the presence of tumor budding on histopathological analysis and high-PAR values. A statistically significant correlation between a high PLR and a good response to neoadjuvant treatment was determined., Conclusions: High PLR values may be associated with a more favorable treatment response to neoadjuvant radio-chemotherapy. A high PAR may be associated with unfavorable histopathological characteristics. Further studies on these readily available biomarkers are required in order to validate their clinical utility., Competing Interests: Declarations of competing interest None., (Copyright © 2024 The Authors.

To date, no parameter with satisfactory accuracy exists for the diagnosis of appendicitis. This retrospective study describes the discriminatory value of preoperative hematologic factors associated with complicated and non-complicated pediatric appendicitis. Clinical and laboratory data were obtained from 294 children diagnosed with appendicitis on admission and treated at our tertiary-level pediatric hospital from 2015 to 2017; they were divided into three groups: control group (n = 118), histologically proven complicated (n = 120), and non-complicated (n = 56) appendicitis. Complicated appendicitis was associated with male preponderance and elevated neutrophil and monocyte levels (all p < 0.001). Non-complicated appendicitis was associated with elevated eosinophil levels (p = 0.023), and unaltered lymphocyte levels (p = 0.30). Compared to non-complicated disease, the lymphocyte-to-monocyte ratio (LMR) was decreased in complicated appendicitis (p = 0.003) but unaltered in the control group (p = 0.38). In the discrimination analysis, LMR had high accuracy (AUC 0.73 ± 0.05; p < 0.001; odds ratio (OR) (95% confidence interval (CI)) 6.0 (2.4–15.3)) and was the only parameter independently associated with complicated appendicitis on regression analysis (OR (95% CI), 0.544 (0.359–0.825); p = 0.004). We identified LMR as a novel potential marker for the differentiation of complicated from non-complicated pediatric appendicitis. This has implications on the treatment approach, either surgical in complicated disease or conservative in non-complicated disease. [ABSTRACT FROM AUTHOR]

Background: This study aimed to evaluate the prognostic effect of LMR in NPC through meta‐analysis. Methods: The prognostic value of LMR for overall survival (OS) and disease‐free survival (DFS)/progression‐free survival (PFS) was evaluated by pooling hazard ratios (HRs) and 95% confidence intervals (CIs). The association between LMR and clinicopathological characteristics was estimated by using odds ratios (ORs) and 95% CIs. Results: A total of 7 studies with 3773 patients were included in this meta‐analysis. The results showed that a low LMR was associated with poor OS (HR = 1.94, 95%CI = 1.71–2.20, p < 0.001) and reduced DFS/PFS (HR = 1.51, 95%CI = 1.23–1.85, p < 0.001) in NPC. Furthermore, a low LMR was significantly associated with male sex (OR = 1.34, 95%CI = 1.12–1.59, p = 0.001), T3‐T4 stage (OR = 1.58, 95%CI = 1.02–2.45, p = 0.040), and tumor stage III‐IV (OR = 1.54, 95%CI = 1.22–1.95, p < 0.001). Conclusions: Our study indicated that a low LMR was correlated with poor survival and advanced tumor stage in patients with NPC. [ABSTRACT FROM AUTHOR]

Advanced therapies for patients with mild-to-severe ulcerative colitis (UC) may result in treatment failure. We examined whether the lymphocyte-to-monocyte ratio (L/M ratio) could predict the failure of advanced therapies. This retrospective, observational, cohort study included 73 patients who were treated with advanced therapies at the Hamamatsu University School of Medicine (Shizuoka, Japan) between February 2011 and November 2020. The patients were divided into the non-failure and failure groups, and their leukocyte counts and ratios before induction were examined. Univariate and multivariate analyses were performed to identify the prognostic factors. Advanced therapies failed within 3 months in 15 (20.5%) patients. Only the L/M ratio was significantly lower in the failure group than in the non-failure group (P  =   0.004). Receiver-operating characteristic (ROC) curve analysis revealed that an L/M ratio of ≤3.417 was predictive of treatment failure; the area under the curve (AUC) was 0.747 (95% CI, 0.620–0.874). Kaplan–Meier analysis revealed that the failure-free rate was significantly lower in the group with an L/M ratio of ≤3.417 than in the group with an L/M ratio of >3.417 (log-rank test P  =   0.002). Cox proportional hazard regression analysis identified an L/M ratio of ≤3.417 as an independent risk factor for failure within 3 months after the induction of advanced therapies. Furthermore, ROC analysis of patients who did not receive immunomodulators also revealed that the cut-off L/M ratio was 3.417 and the AUC was 0.796 (95% CI, 0.666–0.925). In patients receiving advanced therapies for active UC, the L/M ratio can predict treatment failure within 3 months. L/M ratios could facilitate the transition from advanced therapies to subsequent treatments. [ABSTRACT FROM AUTHOR]

Background and Objectives: The inflammatory cells released after intracranial hemorrhage, such as monocytes, macrophages, and neutrophils, activate the inflammatory system. These parameters can be used to evaluate the clinical course of diseases. This study aims to evaluate these parameters as possible predictors for evaluating the development of brain death. Materials and Methods: Patients with a Glasgow coma scale score below 7 were assigned to Group BD (patients with brain death) and Group ICH (intracranial hemorrhage). The neutrophil, lymphocyte, platelet, monocyte counts, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-neutrophil ratio (PNR) were measured at admission. Results: A high WBC count, neutrophil count, NLR, and PLR and a low lymphocyte count, LMR, and PNR were found to be significant for determining brain death. The area under the curve (AUC) values of NLR, PNR, PLR, and LMR to discriminate brain death were 0.63, 0.61, 0.56, and 0.61, respectively. Conclusion: NLR, PNR, PLR, and LMR are easily accessible and reliable parameters that can be used to predict the development of brain death and can be estimated by a simple complete blood count test.

Background: The modified systemic inflammation score (mSIS), which is calculated by a composite score of the lymphocyte-to-monocyte ratio and the albumin content in serum, is identified as the new score to predict the prognosis for various cancers. However, its significance for patients with adenocarcinoma of esophagogastric junction (AEJ), who receive surgery, remains unclear.Methods: This study retrospectively analyzed 317 patients with AEJ receiving surgery between September 2010 and December 2016. The associations between the mSIS and the clinicopathological features, overall survival (OS), as well as relapse-free survival (RFS), were assessed. In addition, the time-dependent receiver operating characteristic (t-ROC) curve analysis was performed for comparing the value of those scoring systems in predicting patient prognosis.Results: Of the 317 cases, 119 were rated as mSIS 0, 123 as mSIS 1, and 75 as mSIS 2. Besides, mSIS was significantly related to age and tumor size. On multivariate analysis, mSIS was identified as a predictor to independently predict OS (p < 0.001) along with RFS (p < 0.001), and a significantly strong correlation was observed at the advanced pTNM stages based on the mSIS system. In the subgroup analysis of adjuvant chemotherapy and surgery alone, mSIS was still the predictor for independently predicting patient OS (p < 0.001) together with RFS (p < 0.001) for the two groups. T-ROC analysis showed that mSIS was more accurate than controlling nutritional status score in predicting OS and RFS.Conclusions: The mSIS can serve as an easy, useful scoring system to independently predict the preoperative survival for AEJ cases undergoing surgery.

Relevance: Accumulating evidence suggests a dysfunction of the para-inflammation in the retinal ganglion cell layer and the optic nerve head in patients with glaucoma. Currently, circulating blood platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and lymphocyte-to-monocyte ratio (LMR) are regarded as novel indicators of systemic inflammation. Biomarkers allow early identification of patients with visual field (VF) loss progression and timely implementation of replacement therapies. Objective: This study aimed to investigate whether higher inflammatory indices (PLR, NLR, and LMR) were associated with VF loss progression in patients with primary angle-closure glaucoma (PACG) for the predictive diagnostics, targeted prevention, and personalization of medical services. Methods: This prospective cohort study followed up 277 patients with PACG for at least 24 months, with clinical examination and VF testing every 6 months. Inflammatory cell quantification, including platelets, neutrophils, lymphocytes, and monocytes, was measured using the Sysmex XN-A1 automated inflammatory cells quantification system. Three systemic inflammatory indices, PLR, NLR, and LMR, were determined on the basis of baseline neutrophil, lymphocyte, monocyte, and platelet counts in patients with PACG. The risk factors for PACG were analyzed using logistic regression, Cox proportional hazards regression, and the Kaplan–Meier curve. Results: Our results revealed that 111 (40.07%) patients showed VF loss progression. The PLR was significantly higher (P = 0.046) in the progression group than in the non-progression group. A higher PLR (OR 1.05, 95% CI 1.01–1.08, P = 0.004) was a risk factor for PACG progression. In multivariate analyses, PLR independently predicted VF loss progression (HR 1.01, 95% CI 1.00–1.01, P = 0.04). Kaplan–Meier curve analysis showed that higher PLR indicated significantly higher rates of VF loss progression (66.91% vs. 52.90%, P = 0.03). Comparable results were observed in the male and female subgroups. Conclusion: Our findings revealed the significant association between a high PLR and a greater risk of VF loss progression in patients with PACG. PLR may be highly recommended as a novel predictive/diagnostic tool for the assessment of VF loss progression from the perspectives of predictive, preventive, and personalized medicine in vulnerable populations and for individual screening.

Background: Neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), and platelet-lymphocyte ratio (PLR) are inflammation markers in inflammatory, cardiovascular, and malignant diseases and are important to assess prognosis. The aim of the study is to show the correlation between the inflammation markers of NLR, LMR, and PLR identified in total blood count of patients with Coronavirus disease 2019 (COVID-19) with the disease severity. Methods: A total of 409 patients attending hospital with clinical symptoms of COVID-19 and with positive quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) test were divided into two groups as 61 severe patients and 348 non-severe patients. The levels of inflammation markers NLR, LMR, PLR, and c-reactive protein (CRP) were assessed. Results: The mean age of 409 patients was 49.9 ± 18.3 years and 48.7% of all patients were female. In the severe patient group, NLR 8.94 ± 13.24, LMR 2.24 ± 1.46, and PLR 248 ± 254 were identified. NLR exhibited the largest area under the curve at 0.698, with the highest specificity (67%) and sensitivity (67.3%) among the other inflammation markers such as LMR and PLR. Consistent with the severity of disease in severe COVID-19 patients, NLR, PLR, CRP and other inflammation markers increase, while LMR is observed to reduce. Conclusions: NLR and PLR, calculated with the simple, cheap, and easily accessible hemogram test requested for diagnosis and follow-up of COVID-19 disease, were correlated with the total score for radiological findings and duration of hospitalization, and we observed NLR and LMR may predict disease severity.

Aims: To investigate the value of previously described pretreatment hematological and biochemical biomarkers as predictors of pathological response. Methods: The authors performed a retrospective analysis of 191 patients with locally advanced rectal cancer who underwent long-course neoadjuvant chemoradiotherapy at two Portuguese centers. The authors performed logistic regression analysis to search for predictive markers of pathological complete and good response. Results: High platelet-neutrophil index (p = 0.042) and clinical tumor stage >2 (p = 0.015) were predictive of poor response. None of the analyzed biomarkers predicted pathological complete response in this study. Conclusion: A high platelet-neutrophil index before neoadjuvant chemoradiotherapy could help predict poorer pathological response in patients with locally advanced rectal cancer. However, no other blood biomarker predicted incomplete or poor response in this study. [ABSTRACT FROM AUTHOR]

Background: In-transit metastasis is considered a locoregional disease in cutaneous melanoma (CM) patients. Isolated limb perfusion (ILP) is among the treatment options in selected cases. The aim of this study was to determine the success of pre- and post-perfusion mSIS values in predicting the potential complications and the prognosis of the disease by investigating the early and long-term results of mSIS values calculated before and after ILP in CM cases with in-transit metastases. Materials and methods: Patients who underwent ILP within the period from 2014 to 2020 in our department were retrospectively scanned. A total of 20 patients were found to undergo ILP. The scores obtained from modified inflammation score (mSIS) were formulated according to albumin (Alb) and lymphocyte to monocyte ratio (LMR) scores. Results: The mean follow-up time was 20.47 months. Complications requiring surgical intervention developed in three patients. According to the Wieberdink local toxicity classification, the majority (70%) of the patients were found to be grade II. Based on pre-perfusion mSIS values, 8 patients were classified as mSIS 0 while six patients were classified as mSIS 1 and 2. Based on post-perfusion mSIS values, 14 patients and one patient were classified as mSIS 2 (70%) and mSIS 0, respectively. Accordingly, univariate analysis showed that mSIS 1 and mSIS 2 were negative prognostic factors for mean survival in the pre-perfusion period (HR 0.162, 95% CI 0.036–0.729; p = 0.018 and HR: 0.223, 95% CI 0.049–1.019; p = 0.053) whereas albumin (Alb) and lymphocyte to monocyte ratio (LMR) were not independent prognostic factors for mean survival. Conclusion: The mSIS values calculated in the pre-perfusion period can give an opinion about the OS of the patients whereas post-perfusion mSIS values may predict potential surgical complications and local toxicities.

Purpose: Systemic inflammatory responses play a key role in cancer progression, and detecting the predictive inflammatory response markers is needed. The present study explored inflammatory response markers capable of predicting survival in patients with gastric cancer. Methods: We enrolled 264 patients, who underwent curative gastrectomy for clinical stage (cStage) I–III gastric cancer between 2012 and 2015. The cut-off point of eight preoperative inflammatory response markers was determined by receiver operating characteristic (ROC) curve analysis. The marker with the highest Harrell's concordance index (C-index) was adopted for subsequent univariate and multivariate analyses using the Cox proportional-hazards model. Results: Among eight representative inflammatory response markers, lymphocyte-to-monocyte ratio (LMR; cut-off point, 4.60) achieved the highest C-index (0.633). The 5-year survival rate was significantly worse in patients with LMR < 4.60 than in those with LMR ≥ 4.60 (67.5% versus 89.0%, P < 0.001). In multivariate analysis, LMR < 4.60 was identified as an independent prognostic factor (hazard ratio: 2.372; 95% confidence interval: 1.266–4.442; P = 0.007). Conclusion: In this study, LMR had the strongest ability to predict the survival of patients with gastric cancer among other inflammatory response markers, with lower LMRs being associated with poor survival following curative gastrectomy.

Minimal residual disease (MRD) is a surrogate marker for survival in multiple myeloma (MM), while the lymphocyte-to-monocyte ratio (LMR) is a prognostic factor associated with the patients' immunological status. We retrospectively evaluated the clinical impact of MRD negativity and LMR. MRD was analyzed by multicolor flowcytometry (threshold, 1 × 10–5). Fifty-eight patients (median age 70 years) who achieved complete response were included in this study. Twenty-two patients received autologous stem cell transplantation, 14 received daratumumab-based chemotherapy, and 22 received another treatment. Forty-one (70.7%) patients achieved MRD negativity. Over the median follow-up time of 15.1 months, PFS in MRD-negative patients was significantly longer than in MRD-positive patients (P = 0.020). In addition, a high LMR at MRD assessment was associated with MRD negativity (P = 0.019) and long PFS (P = 0.009). Finally, neither MRD negativity nor high LMR at MRD assessment was associated with significantly shorter PFS compared with MRD positivity or low LMR (P = 0.002). In conclusion, high LMR was associated with MRD negativity and can be used as a predictor of long PFS. Change of treatment strategy might be essential for patients with MRD positivity and high LMR at MRD assessment due to their short PFS. [ABSTRACT FROM AUTHOR]

Objectives: Tumor budding (TB), tumor stroma ratio (TSR), tumor infiltrating pattern (TIP), and preoperative lymphocyte-tomonocyte ratio (LMR) were previously reported to be useful prognostic factors in colorectal cancer (CRC); however, the correlation among these markers and their individual prognostic potency have not been extensively studied. Methods: A cohort of 147 stage I-IV CRC patients was obtained retrospectively, and the patients were divided into subgroups based on low or high TB/TSR/LMR, TIPa (expansile+intermediate) and TIPb (infiltrative) values. The differences in relapse-free survival (RFS) and overall survival (OS) intervals among these subgroups were determined by Kaplan-Meier analysis followed by log-rank tests. The Cox proportional hazard model was applied for the univariate and multivariate analysis of RFS and OS rates. Results:TB, TIP, and LMR, but not TSR, are useful markers for predicting patient survival. Patients with a poor histological grade and large tumor diameter were more likely to present with high TB, TIPb, and low LMR values; in addition, those with advanced T, N, and TNM stages and elevated preoperative CA199 levels had high TB and TIPb levels. TB, TIP, and LMR were significant prognostic factors for the RFS (TB: HR [hazard ratio] =2.28, 95% CI =1.30-4.00, P < .01; TIP: HR=2.60, 95% CI=1.46-4.60, P < .01; LMR: HR=0.79, 95% CI =0.65-0.96, P =.02) and OS (TB: HR =2.43, 95% CI =1.32-4.48, P < .01; TIP: HR=2.49, 95% CI=1.34-4.63, P < .01; LMR: HR=0.79, 95% CI =0.64-0.98, P=.03) intervals. In addition, TB and LMR were independent prognostic factors for the RFS interval (TB: HR =1.80, 95% CI =1.01-3.19, P =.05; LMR: HR=0.80, 95% CI =0.67-0.96, P=.01), but only LMR was an independent factor for OS rates (HR =0.80, 95% CI =0.65-0.98, P=.03). Conclusion: Although TB, TIP, and LMR are useful prognostic markers for CRC, the LMR is likely to be the only independent prognostic factor for both RFS and OS outcomes in practice.

In a recent article in Leukemia & Lymphoma, Mozas et al. [1] analyze the prognostic impact of the lymphocyte/monocyte ratio (LMR) in follicular lymphoma (FL). They report an optimal LMR cutoff of 2.5 for progression-free survival (PFS) and overall survival (OS). Mozas et al. [1] are not the first to look into this issue, but their cohort is the largest, being over three times the size of –and with longer follow-up than –most other reports (Table 1).

Introduction: Patients with unresectable or recurrent gastric cancer who have an objective response (OR) to nivolumab monotherapy are expected to have a good long-term prognosis. However, the OR rate for nivolumab treatment is low at 11%, and there is a need for biomarkers to predict the treatment response. This study aimed to analyze the significance of systemic inflammation-related variables and clinicopathologic characteristics as predictive markers of response to nivolumab monotherapy in patients with advanced gastric cancer. Methods: In this retrospective cohort study, we enrolled 71 consecutive patients who received nivolumab monotherapy for unresectable or recurrent gastric cancer. Receiver operating characteristic curve analysis was performed to determine the cutoff values of systemic inflammation-related variables, predictors of treatment response, and other prognostic factors related to nivolumab therapy. We focused on systemic inflammation-related variables measured before nivolumab induction and 2 weeks after its first administration and performed multivariate analysis to assess whether they could be used as prognostic factors. Results: Multivariate analysis revealed that a lymphocyte-to-monocyte ratio (LMR) of ≤3.28 after 2 weeks of initial nivolumab treatment (2wLMR) is a statistically significant predictor of treatment response (p = 0.012). The progression-free survival (PFS) rate of patients with liver metastasis was significantly worse than that of the other patients (1-year PFS: 0.0 vs. 24.4%, respectively; p = 0.005). The overall survival (OS) of patients with a low 2wLMR was significantly longer than that in patients with a high 2wLMR (1-year OS: 37.4 vs. 18.9%, respectively; p = 0.022). Conclusions: Thus, the 2wLMR could be a useful biomarker to predict response to nivolumab treatment and the prognosis of unresectable and recurrent gastric cancer. [ABSTRACT FROM AUTHOR]

Aim of the study: Prognostic scores are highly needed to properly manage children with cirrhosis and improve their clinical outcomes. The relationship between lymphocyte-to-monocyte ratio (LMR) at the time of admission to hospital and outcome of cirrhosis has been studied in adults, but to the best of our knowledge, there is no study regarding its utility as a prognostic marker of poor outcome in children with cirrhosis. Thus, this study aimed to investigate the potential prognostic value of LMR in such patients. Material and methods: At the time of admission, LMR, Child-Pugh, and Pediatric End-stage Liver Disease/Model for End-stage Liver Disease (PELD/MELD) scores were calculated for 114 children with cirrhosis. LMR and PELD/MELD and Child-Pugh scores were compared between the survivor and non-survivor groups. Receiver operator characteristic (ROC) curve analysis was performed and the cutoff values were calculated using the Youden index. Results: It was found that LMR had a strong negative correlation with PELD/MELD (r = -0.87, p = 0.36) and a weak negative correlation with Child-Pugh scores (r = -0.046, p = 0.63). The highest area under the curve (AUC) was found for LMR (0.861). The AUC was also good for PELD/MELD scores (0.804). The AUC values for LMR in patients under and above 6 years old were 0.675 (95% CI: 0.462-0.888) (p = 0.111) and 0.926 (95% CI: 0.852-1.000) (p < 0.001), respectively. The PELD/MELD scores were significantly higher in the low LMR group than in the high LMR group (p = 0.001). Conclusions: LMR can be used to determine the outcome of cirrhotic children older than 6 years during the hospital stay because it is easy to calculate and its efficacy is comparable to PELD/MELD scores. Meanwhile, further studies are needed to confirm these preliminary results. [ABSTRACT FROM AUTHOR]

Context: Serum inflammation-based scores reflect systemic inflammatory response and/or patients' nutritional status, and may predict clinical outcomes in cancer. While these are well-described and increasingly used in different cancers, their clinical usefulness in the management of patients with endocrine tumors is less known. Evidence acquisition: A comprehensive PubMed search was performed using the terms "endocrine tumor," "inflammation," "serum inflammation-based score," "inflammatorybased score," "inflammatory response-related scoring," "systemic inflammatory response markers," "neutrophil-to-lymphocyte ratio," "neutrophil-to-platelet ratio," "lymphocyteto-monocyte ratio," "Glasgow prognostic score," "neutrophil-platelet score," "Systemic Immune-Inflammation Index," and "Prognostic Nutrition Index" in clinical studies. Evidence synthesis: The neutrophil-to-lymphocyte ratio and the platelet-to-lymphocyte ratio are the ones most extensively investigated in patients with endocrine tumors. Other scores have also been considered in some studies. Several studies focused in finding whether serum inflammatory biomarkers may stratify the endocrine tumor patients' risk and detect those at risk for developing more aggressive and/or refractory disease, particularly after endocrine surgery. Conclusions: In this review, we summarize the current knowledge on the different serum inflammation-based scores and their usefulness in predicting the phenotype, clinical aggressiveness, and disease outcomes and prognosis in patients with endocrine tumors. The value of such serum inflammation-based scores in the management of patients with endocrine tumors has been emerging over the last decade. However, further research is necessary to establish useful markers and their cut-offs for routine clinical practice for individual diseases. [ABSTRACT FROM AUTHOR]

Introduction The purpose of the present study was to evaluate the potential relationship of lymphocyte-to-monocyte ratio (LMR) with outcomes of septic patients at intensive care unit (ICU) admission. Material and methods 3087 septic patients were included in the final cohort by using the Medical Information Mart for Intensive Care (MIMIC) database. We evaluated the association of different groups of LMR max with 28-day survival and 1-year survival via Kaplan-Meier (K-M) analysis and Cox regression analysis. Subgroups analysis of LMR max was performed to further explore the effect of LMR max on survival. Results According to the optimal cut-off value, the cohort was divided into low-LMR max and high-LMR max groups. The 28-day and 1-year survival rates were 47.9% and 19.9%, respectively, in the low-LMR max group, and 60.4% and 25.9%, respectively, in the high-LMR max group. Univariate logistic regression and K-M analyses revealed that the 28-day and 1-year survival rates of the high-LMR max group were higher than those of the low-LMR max group (both p < 0.001). A subgroup analysis of LMR max identified a significant stepwise decrease in the risk of death at 28 days and 1 year from group 1 to group 4 (LMR max increased gradually) after adjustment for multiple variables. Conclusions We report for the first time that a lower LMR max value is independently predictive of a poor prognosis in septic patients. Therefore, as an inexpensive and readily available indicator, LMR max may facilitate stratification of prognosis in septic patients.

Abstract Background Within the last years, the interest in physical exercise as non-invasive stimulus influencing circulating hematopoietic stem and progenitor cell (CPC) concentrations has constantly grown. Cell estimates are often derived by determining the subgroup of CPC as percent lymphocytes (LYM) or mononuclear cells (MNC) via flow cytometry and back calculation over whole blood (WB) cell counts. However, results might depend on the used cell isolation technique and/or gating strategy. We aimed to investigate MNC loss and apoptosis during the flow cytometry sample preparation process preceded by either density gradient centrifugation (DGC) or red blood cell lysis (RBCL) and the potential difference between results derived from back calculation at different stages of cell isolation and from WB. Methods Human blood was subjected to DGC and RBCL. Samples were stained for flow cytometry analysis of CPC (CD34+/CD45dim) and apoptosis analysis (Annexin V) of MNC and CPC subsets. MNC and LYM gating strategies were compared. Results Both DGC as well as RBCL yielded comparable CPC concentrations independent of the gating strategy when back calculated over WB values. However, cell loss and apoptosis differed between techniques, where after DGC LYM, and monocyte (MONO) concentrations significantly decreased (p

The predictive and prognostic role of the lymphocyte-to-monocyte ratio (LMR) has been reported in other cancers. The aim of our present study was to explore the value of LMR prognostic prediction in high-risk PTC patients.Patients and Methods: Two hundred and twenty-four PTC high-risk cases at West China Hospital were randomized into a training set (112 cases) and testing set (112 cases), while 48 cases in Shang Jin Nan Fu Hospital were included as the external validation set.Results: A lower preoperative LMR correlated with larger tumor size, advanced N and M stages, and an increased number of multiple PTC cases in the training, testing, and validation sets (all P

Background The neutrophil‐to‐lymphocyte ratio (NLR), platelet‐to‐lymphocyte ratio (PLR), and lymphocyte‐to‐monocyte ratio (LMR) are reported to show a strong correlation with prognosis in patients with non‐small cell lung cancer (NSCLC). We aimed to describe a novel scoring system combining these ratios, termed the inflammatory response biomarker (IRB) score, and test its prognostic value in NSCLC. Methods The data of 261 NSCLC patients who underwent thoracoscopic radical resection in a single center were retrospectively reviewed. The IRB score was defined as follows: a high NLR (> 2.12), a high PLR (92.9), and a low LMR (< 4.57) were each scored as 1; the opposite values were scored as 0. The individual scores were added to produce the IRB score (range: 0–3). Results Multivariate analyses indicated that high tumor node metastasis (TNM) stage (hazard ratio [HR] 2.721, 95% confidence interval [CI] 1.597–4.989; P

Abstract Background and Aim Although the Cancer of the Liver Italian Program (CLIP) score is useful for prognostication of patients with hepatocellular carcinoma (HCC), a previous study has reported that the CLIP score was unable to stratify the postoperative outcomes of HCC patients in whom the score was low (0‐1). Recent studies have reported that the preoperative lymphocyte‐to‐monocyte ratio (LMR) is useful for prognostication of patients with various cancer. Methods We reviewed 329 HCC patients with a low CLIP score (0‐1) undergoing curative resection. This study had the approval of the Institutional Review Board (28068). Multivariate analyses were carried out to detect clinical factors correlating with overall survival (OS). Kaplan‐Meier analysis and the log‐rank test were used for comparison of OS. Results Multivariate analysis showed that LMR (

Abstract Introduction Prognostic biomarkers are highly needed to properly manage patients with cancer and improve their clinical courses. The relationship between lymphocyte-to-monocyte ratio (LMR) at diagnosis and ovarian cancer prognosis has been extensively studied, but little consensus has been reached regarding its utility as a biomarker of poor outcome. Thus, this study aimed to investigate the potential prognostic value of pretreatment LMR in such patients to shed light on this issue. Methods We searched the scientific databases of MEDLINE, Embase, Cochrane Library, and WangFang for relevant studies about the inflammatory prognostic factor LMR in ovarian cancer, based on specific inclusion and exclusion criteria. The following parameters were analyzed among others: LMR values and respective cut-offs, patient’s overall survival (OS) and progression-free survival (PFS), and clinicopathological features. Results Eight studies, including 2259 patients, were eligible for inclusion in this meta-analysis. We found that low LMR was associated with both poor OS [Hazard ratio (HR): 1.92; 95% confidence interval (CI): 1.58–2.34; p

BackgroundDynamic changes in circulating immune-inflammatory cells have been regarded as simple and convenient prognostic biomarkers in various cancers. However, studies on the prognostic values of their ratios in oral squamous cell carcinoma (OSCC) remain limited.Materials and MethodsA total of 493 OSCC patients were included in the present study. Here, we investigated the prognostic values of the neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), neutrophil-to-white blood cell ratio (NWR), and lymphocyte-to-white blood cell ratio (LWR) in OSCC. The correlations of the NLR, LMR, NWR, and LWR with clinicopathological characteristics were statistically analyzed using the Chi-square test, Kaplan-Meier curves, and univariate and multivariate Cox regression models.ResultKaplan-Meier analyses revealed that OSCC patients with a high LMR and low NWR had prolonged overall survival (OS, P

Background: The post-operative acute kidney injury (AKI) represents a common complication in the Acute Debakey Type I Aortic Dissection (ADTIAD) and predicts a poorer prognosis. The clinical evidence is scarce supporting the predictive value of the pre-operative lymphocyte-to-monocyte ratio (LMR) in post-operative AKI in ADTIAD.Methods: In this retrospective cohort study, 190 consecutive patients with ADTIAD enrolled for surgical treatment between January 1, 2013, and December 31, 2018. The diagnosis of AKI followed the Kidney Disease: Improving Global Outcomes guidelines (KDIGO). Pre-operative LMR and other possible risk factors were analyzed for their prognostic value in the post-operative AKI in ADTIAD.Results: The subjects were assigned to the low-LMR and high-LMR groups according to the median value of pre-operative LMR. For post-operative AKI, the incidence and the severity in the low-LMR group were statistically different from that of the high-LMR group. Besides, the lower LMR was statistically associated with the more extended ICU stay and intubation time and higher incidences of ischemic stroke and in-hospital mortality. Additionally, in the multivariable analysis, the pre-operative LMR was an independent predictor for post-operative AKI in ADTIAD. A predictive model for post-operative AKI in ADTIAD was established incorporating LMR.Conclusions: LMR is an independent prognostic indicator incorporated into the predictive model with other risk factors to predict the post-operative AKI in ADTIAD.

Background: Dynamic changes in circulating immune-inflammatory cells have been regarded as simple and convenient prognostic biomarkers in various cancers. However, studies on the prognostic values of their ratios in oral squamous cell carcinoma (OSCC) remain limited. Materials and Methods: A total of 493 OSCC patients were included in the present study. Here, we investigated the prognostic values of the neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), neutrophil-to-white blood cell ratio (NWR), and lymphocyte-to-white blood cell ratio (LWR) in OSCC. The correlations of the NLR, LMR, NWR, and LWR with clinicopathological characteristics were statistically analyzed using the Chi-square test, Kaplan-Meier curves, and univariate and multivariate Cox regression models. Result: Kaplan-Meier analyses revealed that OSCC patients with a high LMR and low NWR had prolonged overall survival (OS, P <0.001) and disease-free survival (DFS, P <0.001 and P =0.003, respectively), but there were no significant differences in metastasis-free survival (MFS, P =0.053 and P =0.052, respectively). In contrary, a high NLR and low LWR were associated with poor OS (P <0.001 and P =0.0016, respectively), DFS (P =0.0014 and 0.0012, respectively) and MFS (P =0.021 and 0.008, respectively). Additionally, Cox multivariate analyses showed that the LMR was an independent prognostic factor for both OS (P =0.007) and DFS (P= 0.017), while the LWR was an independent prognostic factor for MFS (P =0.009). Conclusion: Preoperative NLR, LMR, NWR, and LWR in the peripheral blood are significant prognostic factors for OSCC and might be helpful in predicting OSCC progression. [ABSTRACT FROM AUTHOR]

Lymphocyte-to-monocyte ratio (LMR) has been reported as a biomarker for predicting the prognosis of colorectal cancer. However, the clinical usefulness of LMR requires detailed research, which can contribute to better therapeutic strategies. A cohort of 554 patients with resectable advanced colon cancer in our institution was analyzed retrospectively. An analysis of stages II and III resectable advanced colon cancer was performed. LMR was useful for predicting overall survival (OS) and relapse-free survival (RFS). The ROC curve revealed an LMR value of 2.77 as a cutoff for OS. A high LMR was an independent prognostic factor and was associated with a high hazard ratio (HR) in all cases for OS (HR = 0.530, 95% confidence interval (CI) = 0.334–0.842, p = 0.007). A high LMR was not an independent prognostic factor in stage II cases but was a predictor with the strongest association with prognosis in patients with stage III cases for OS (HR = 0.383, 95% CI = 0.160–0.915, p = 0.031). LMR is a strong predictor of prognosis in patients with stage III colon cancer and may be useful in postoperative treatment options. [ABSTRACT FROM AUTHOR]
