Monocyte-to-lymphocyte ratio as a prognostic factor in peripheral whole blood samples of colorectal cancer patients

BACKGROUND Colorectal cancer is the third most common malignancy worldwide.Therefore,it is critically important to identify new useful markers that can be easily obtained in routine practice.Inflammation is a crucial issue in the pathogenesis and development of cancer.AIM To evaluate the prognostic value of absolute monocyte count,monocyte to lymphocyte ratio(MLR),the combination of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio(NLR-PLR),and combined platelet and neutrophilto-lymphocyte ratio(PLT-NLR)in peripheral blood samples of patients with colorectal cancer undergoing surgery.METHODS We conducted a retrospective study of 160 patients with colorectal cancer who underwent surgery,and 42 healthy controls.The status of absolute monocyte count,MLR,NLR-PLR and PLT-NLR was calculated on the basis of blood samples obtained before and after surgery.Haematologic factors were examined in correlation with the type of tumour growth,tumour size,histological type,percentage of mucinous component,grade of malignancy,Tumour-Node-Metastasis stage,venous,lymphatic and perineural invasion of cancer cells,status of lymph node invasion and the presence of cancer cell deposits.The Kaplan-Meier method and the long-rank test were used to compare survival curves.To determine independent prognostic factors,univariate and multivariate Cox proportional hazards regression models were applied.RESULTS The PLT-NLR status was correlated with tumour size and the presence of perineural invasion(P=0.015;P=-0.174,P=0.037).Moreover,high NLR-PLR and PLR-NLR ratios in the blood samples obtained after surgery were positively associated with histological type of cancer and percentage of the mucinous component(NLR-PLR:P=0.002;P=0.009;PLR-NLR status:P=0.002;P=0.007).The analysis of 5-year disease-free survival showed that the MLR of whole blood obtained after surgery[HR=2.903,95%CI:(1.368-6.158),P=0.005]and the status of lymph node metastasis[HR=0.813,95%CI:(0.653-1.013),P=0.050]were independent prognostic factors in colorectal cancer patients.CONCLUSION The postoperative MLR in whole blood samples can be used as an independent prognostic factor in patients diagnosed with colorectal cancer.

Systemic immune inflammation index, ratio of lymphocytes to monocytes, lactate dehydrogenase and prognosis of diffuse large Bcell lymphoma patients

BACKGROUND In malignant tumors,inflammation plays a vital role in the development,invasion,and metastasis of cancer cells.Diffuse large B-cell lymphoma(DLBCL),the most common malignant proliferative disease of the lymphatic system,is commonly associated with inflammation.The international prognostic index(IPI),which includes age,lactate dehydrogenase(LDH),number of extranodal lesions,Ann Arbor score,and Eastern Cooperative Oncology Group(ECOG)score,can evaluate the prognosis of DLBCL.However,its use in accurately identifying highrisk patients and guiding treatment is poor.Therefore,it is important to find novel immune markers in predicting the prognosis of DLBCL patients.AIM To determine the association between the systemic immune inflammation index(SII),ratio of lymphocytes to monocytes(LMR),ratio of LMR to LDH(LMR/LDH),and prognosis of patients with DLBCL.METHODS A total of 68 patients diagnosed with DLBCL,treated in our hospital between January 2016 and January 2020,were included.χ2 test,Pearson’s R correlation,Kaplan Meier curves,and Cox proportional risk regression analysis were used.The differences in the SII,LMR,and LMR/LDH among patients with different clinicopathological features were analyzed.The differences in progression-free survival time among patients with different SII,LMR,and LMR/LDH expressions and influencing factors affecting the prognosis of DLBCL patients,were also analyzed.RESULTS The LMR and LMR/LDH in patients with Ann Arbor stage III–IV,ECOG score≥2,and SII,IPI score 2–5 were significantly higher than those of patients with Ann Arbor stage I-II and ECOG score<2(P<0.05).Patients with high SII,LMR,and LMR/LDH had progression-free survival times of 34 mo(95%CI:32.52–38.50),35 mo(95%CI:33.42–36.58)and 35 mo(95%CI:33.49–36.51),respectively,which were significantly lower than those with low SII,LMR,and LMR/LDH(P<0.05);the SII,LMR,and LMR/LDH were positively correlated(P<0.05).Cox proportional risk regression analysis showed that the SII,LMR,and LMR/LDH were influencing factors for the prognosis of DLBCL patients(hazard ratio=1.143,1.665,and 1.704,respectively;P<0.05).CONCLUSION The SII,LMR,and LMR/LDH are related to the clinicopathological features of DLCBL,and they also influence the prognosis of patients with the disease.

Prognostic value of neutrophil/lymphocyte,platelet/lymphocyte,lymphocyte/monocyte ratios and Glasgow prognostic score in osteosarcoma:A meta-analysis

BACKGROUND Some studies investigated the prognostic role of several blood biomarkers,including the neutrophil/lymphocyte ratio(NLR),platelet/lymphocyte ratio(PLR),lymphocyte/monocyte ratio(LMR)and Glasgow prognostic score(GPS),in osteosarcoma,but their results were inconsistent with each other.AIM To identify the prognostic value of NLR,PLR,LMR and GPS in osteosarcoma patients through reviewing relevant studies.METHODS The PubMed,EMBASE,Web of Science and CNKI databases were searched up to October 2,2021.The primary and second outcomes were overall survival(OS)and disease-free survival(DFS),respectively.The hazard ratios(HRs)with 95%confidence intervals(CIs)were combined to assess the association between these indicators and prognosis of osteosarcoma patients.RESULTS A total of 13 studies involving 2087 patients were eventually included.The pooled results demonstrated that higher NLR and GPS were significantly associated with poorer OS(HR=1.88,95%CI:1.38-2.55,P<0.001;HR=2.19,95%CI:1.64-2.94,P<0.001)and DFS(HR=1.67,95%CI:1.37-2.04,P<0.001;HR=2.50,95%CI:1.39-4.48,P<0.001).However,no significant relationship of PLR and LMR and OS(P=0.085;P=0.338)and DFS(P=0.396;P=0.124)was observed.CONCLUSION Higher NLR and GPS were related with worse prognosis and might serve as novel prognostic indicators for osteosarcoma patients.

Lymphocyte-to-monocyte ratio can predict mortality in pancreatic adenocarcinoma

AIM To determine if the lymphocyte-to-monocyte ratio(LMR) could be helpful in predicting survival in patients with pancreatic adenocarcinoma.METHODS We retrospectively reviewed the medical records of all patients diagnosed with pancreatic adenocarcinoma in the VA North Texas Healthcare System from January 2005 to December 2010. The LMR was calculated from peripheral blood cell counts obtained at the time of diagnosis of pancreatic cancer by dividing the absolute lymphocyte count by the absolute monocyte count. A Univariable Cox regression analysis was performed using these data, and hazard ratios(HR) and 95%CI were calculated. The median LMR(2.05) was used to dichotomize patients into high-LMR and low-LMR groups and the log rank test was used to compare survivalbetween the two groups.RESULTS We identified 97 patients with pancreatic adenocarcinoma(all men, 66% white, 30% African-American). The mean age and weight at diagnosis were 66.0 ± 0.9(SEM) years and 80.4 ± 1.7 kg respectively. Mean absolute lymphocyte and monocyte values were 1.50 ± 0.07 K/mL and 0.74 ± 0.03 K/mL respectively. Mean, median and range of LMR was 2.36, 2.05 and 0.4-12 respectively. In the univariable Cox regression analysis, we found that an increased LMR was a significant indicator of improved overall survival in patients with pancreatic adenocarcinoma(HR = 0.83; 95%CI: 0.70-0.98; P = 0.027). Kaplan-Meier analysis revealed an overall median survival of 128 d(95%CI: 80-162 d). The median survival of patients in the high-LMR(> 2.05) group was significantly greater than the low-LMR group(≤ 2.05)(194 d vs 93 d; P = 0.03), validating a significant survival advantage in patients with a high LMR.CONCLUSION The LMR at diagnosis is a significant predictor for survival and can provide useful prognostic information in the management of patients with pancreatic adenocarcinoma.

The prognostic value of lymphocyte-to-monocyte ratio in retinopathy of prematurity

AIM: To evaluate the associations between development of retinopathy of prematurity(ROP) and serum lymphocyteto-monocyte ratio(LMR), neutrophil-to-lymphocyte ratio(NLR), and platelet-to-lymphocyte ratio(PLR). METHODS: A retrospective cohort study was performed, involving infants who were screened for ROP from January 2015 to December 2015. Preterm newborns of ≤32 gestational weeks with ROP were enrolled as the observation group, and non-ROP infants were enrolled as the control group, whose complete blood cell were measured within the first 24 h of life. The levels of NLR, LMR and PLR were determined in all groups. The data obtained were analyzed using univariate and multivariate logistic regression analysis.RESULTS: In this study, 40 cases of ROP were enrolled and 40 cases of non-ROP as controls. The LMR levels were significantly higher(P<0.001) in ROP group(3.96±1.16) compared to non-ROP group(2.85±0.79). The NLR levels were significantly lower(P=0.035) in ROP group {median [interquartile range(IQR)], 0.88(0.67-1.46)} compared to non-ROP group [median(IQR), 1.20(0.85-1.89)]. The median PLR values were 61.99(IQR, 50.23-75.98) in ROP group and 69.24(IQR, 55.52-88.12) in non-ROP group(P=0.104). Logistic regression analysis suggested that LMR was an independent risk factor for ROP(OR: 0.275; 95% CI: 0.134-0.564; P=0.001). CONCLUSION: The findings demonstrate that higher LMR is independently and significantly associated with the development of ROP, and the LMR may be invoked as a predictive tool for identifying risk for ROP.

The combined prognostic value of pretreatment neutrophil-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and platelet-to-lymphocyte ratio in stage IE/IIE extranodal natural killer/T-cell lymphoma

Objective This study aimed to explore the combined prognostic value of pretreatment neutrophil-tolymphocyte ratio(NLR), lymphocyte-to-monocyte ratio(LMR), and platelet-to-lymphocyte ratio(PLR) in newly diagnosed IE/IIE extranodal natural killer/T-cell lymphoma(ENKTL) treated with a P-Gemox regimen combined with radiotherapy or radiotherapy alone.Methods A total of 132 patients from 2009 to 2017 at the Sichuan Cancer Hospital were enrolled in the study. The cutoff values of NLR, LMR, and PLR using overall survival(OS) rate as an endpoint were obtained by the receiver operating curve. Results The cutoff value of NLR was 3.5. Patients with high NLR had significantly shorter progressionfree survival(PFS)(P < 0.001) and OS(P < 0.001) than those with low NLR. Similarly, the cutoff value of LMR was 3.0. The high LMR group had significantly longer PFS(P=0.001) and OS(P < 0.001) than the low LMR group. Similarly, the cutoff value of PLR was 191.7. The high PLR group was significantly associated with poor PFS(P < 0.001) and OS(P < 0.001) than the low PLR group. Furthermore, combining NLR, LMR, and PLR to build a new model to stratify patients into low-, intermediate-, intermediate-high-, and high-risk groups, there were also significant differences in PFS(P < 0.001) and OS(P < 0.001). The univariate analysis showed that presenting B symptoms, stage IIE, local tumor invasion, Eastern Cooperative Oncology Group score ≥ 2, elevated lactate dehydrogenase level, elevated NLR, decreased LMR, and elevated PLR were significantly associated with poor survival. The multivariate analysis demonstrated that PLR was an independent prognostic factor for both PFS(hazard ratio [HR]= 2.073, 95% confidence interval [CI]= 1.080–3.981, P = 0.028) and OS(HR = 2.127, 95% CI = 1.102–4.107, P = 0.025).Conclusion Elevated pretreatment PLR was a novel simple predictor of poor survival in patients with stage IE/IIE ENKTL. Combining NLR, LMR, and PLR could provide additional stratification.

Association of the Monocyte to HDL Cholesterol Ratio with Thrombus Burden in Patients with Acute Coronary Syndrome

Background: Intracoronary thrombus burden is associated with some adverse events and poor prognosis in patients with Acute Coronary Syndrome. Identifying predictors of the intracoronary thrombus burden may contribute to the management of Acute Coronary Syndrome. Objective: To assess the correlation between the Monocyte to HDL Cholesterol ratio with thrombus burden in patients with Acute Coronary Syndrome. Patients and Methods: 138 patients with ACS who were admitted to CCU department in National Heart Institute Cairoand Menoufia University Hospitals, Menoufia, underwent primary percutaneous coronary intervention (PCI).Angiographic thrombus burden was classified based on thrombolysis in myocardial infarction (TIMI) thrombus grades. The patients were grouped into 2 categories of low thrombus burden (grades 0 - 3) (49.7%) and high thrombus burden (grades 4 and 5) (50.3%). Results: On analysis we found that the MHR was significantly higher in the high thrombus burden group compared with the low thrombus (0.052 ± 0.019 vs 0.014 ± 0.008);P 0.001. Conclusion: Among Acute Coronary Syndrome patients underwent Primary PCI, MHR was independent predictor of high thrombus burden in patients with Acute Coronary Syndrome.

Evaluation of the neutrophil-lymphocyte ratio, platelet-lymphocyte ratio and monocyte lymphocyte ratio for diagnosis of testicular torsion

Objective:To explore the value of complete blood count(CBC),including neutrophil-lymphocyte ratio(NLR),platelet-lymphocyte ratio(PLR),and monocyte lymphocyte ratio(MLR)in diagnosis of testicular torsion(TT)and differential diagnosis from epididymo-orchitis.Methods:The study was conducted at the Antalya Training and Research Hospital Emergency Department in Turkey with acute scrotal pain patients from January 1st,2016 to January 1st,2018.The patients were categorized into 3 groups:the TT group who underwent an operation for TT(n=70),the epididymo-orchitis group who received epididymo-orchitis treatment(n=120),and the healthy control group(n=100).NLR,PLR,and MLR of the three groups were analysed and compared.The optimum cut-off values of NLR,MLR,and PLR were analyzed.Results:Mean NLR and MLR values were significantly higher in the epididymo-orchitis group and the TT group compared to the control group(P<0.001).Receiver operating characteristic analysis revealed a sensitivity of 77.1%and a specificity of 80%for NLR(77.1)and a sensitivity of 68.2%and a specificity of 78%for PLR(124.80).Moreover,when MLR was used to differentiate the two treatment groups,the optimal cut-off value had a sensitivity of 67.1%and a specificity of 75%(AUC:0.677-0.826,P<0.001).Conclusions:NLR,PLR,and MLR might be associated with the diagnosis of TT.These parameters provide a useful and economical method to help diagnose TT in the emergency department.

The Lower Peripheral Blood Lymphocyte to Monocyte Ratio Following Completion of First Line Chemotherapy Is a Risk Factor for Predicting Relapse in Patients with Diffuse Large B-Cell Lymphoma

Background and objective: During routine follow up, there is no specific predictor to ascertain relapse after standard first line chemotherapy in diffuse large cell lymphoma. Therefore, this study was designed to assess the prognostic significance of the ratio between absolute lymphocyte and monocyte counts (LMR) in the peripheral blood to verify relapse in diffuse large B cell lymphoma. Patients and methods: A total of 139 patients with newly diagnosed diffuse large B cell lymphoma (DLBCL) were evaluated and treated with CHOP or R-CHOP between the years 2009 and 2016. Three months following completion of first line therapy, Lymphocyte/monocyte ratio (LMR) was calculated from the routine automated complete blood cell count (CBC) attained a plateau after the bone marrow recovery after first line chemotherapy. The absolute lymphocyte count/absolute monocyte count ratio (LMR) was calculated by dividing the ALC by the AMC. Results: ROC curve analysis of 139 patients established 2.8 as cutoff point of LMR for relapse with AUC of 0.97 (95% CI 0.93 - 0.99, P ≤ 0.001). Cox regression analysis was performed to identify factors predicting relapse. In univariate regression analysis, ALC (95% CI 0.003 - 0.03, p ≤ 0.001), AMC (95% CI 15.4 - 128.8, p ≤ 0.001), LMR (95% CI 0.001 - 0.01, p ≤ 0.001), and LDH (95% CI 0.1 - 0.5, p ≤ 0.001) following completion of therapy are significant factors for relapse. Other significant factors for relapse are Ann Arbor stage (95% CI 1.1 - 6.9, P = 0.03), extranodal sites (95% CI 1.2 - 6.1, P = 0.01), age (95% CI 1.3 - 6.5, P = 0.01) and treatment of CHOP protocol (95% CI 0.05 - 0.6, P = 0.007). In a multivariate analysis LMR following completion of therapy was predictive for relapse (95% CI 0.001 - 0.2, P = 0.005). ALC was also significant in multivariate analysis (95% CI 0.01 - 0.8, P = 0.03). LDH following completion of therapy (95% CI 0.2 - 14.9, P = 0.5), AMC following completion of therapy (95% CI 0.3 - 43.1, P = 0.3), age (95% CI 0.9 - 205.4, P = 0.06), extra-nodal sites (95% CI 0.04 - 9.8, P = 0.8), Ann Arbor stage (95% CI 0.3 - 28.7, P = 0.3), and Treatment of CHOP protocol (95% CI 0.01 - 2.4, P = 0.2) were not statistically significant. Conclusion: This study observed that LMR assessed after first line chemotherapy during routine follow up is an independent predictor of relapse and clinical outcome in DLBCL patients. LMR at follow up can be used a simple inexpensive biomarker to alert clinicians for relapse during follow up after standard first line chemotherapy in DLBCL patients.

Absolute Lymphocyte/Monocyte Ratio at Diagnosis and Interim Positron-Emission Tomography Predict Survival in Classical Hodgkin Lymphoma

Interim Positron-Emission Tomography (int-PET) and the peripheral blood absolute lymphocyte/monocyte ratio at di- agnosis (ALC/AMC-DX) have been shown to be predictors for progression-free survival (PFS) and time to progression (TTP) in classical Hodgkin lymphoma (cHL). Therefore, we studied if the combination of ALC/AMC-DX and the (int-PET) can further stratified PFS and TTP in cHL patients. Patients were required to be diagnosed, treated, and followed with int-PET at Mayo Clinic, Rochester, Minnesota. From 2000 until 2008, 111 cHL patients qualified for the study. The median follow-up was 2.8 years (range: 0.3 - 10.4 years). Patients with a negative int-PET (N = 98) pre- sented with a higher ALC/AMC-DX (median of 2.32, range: 0.26 - 37.5) compared with patients with a positive int-PET (N = 13) (median of 0.9, range: 0.29 - 3.10), p 1.1. Group 1 experienced superior PFS and TTP in comparison with the other groups. In conclusion, the combination of ALC/AMC-DX and the int-PET provides a simple model to assess clinical outcomes in cHL.

Research progress of monocyte/high density lipoprotein ratio in cardiovascular diseases

In recent years,monocyte to high density lipoprotein cholesterol ratio(MHR)has attracted wide attention as a new marker of inflammatory response.This indicator includes two aspects:inflammatory response and lipid accumulation,which are the two most basic characteristics of Atherosclerosis(AS).AS is closely related to the occurrence of Cardiovascular diseases(CVD).A large number of existing studies have confirmed that MHR is an inflammatory marker that can dynamically reflect the trend of inflammation,can reflect the chronic inflammatory response in blood vessels,and can evaluate the occurrence,development and prognosis of cardiovascular disease in a non-invasive manner.This article reviews recent studies on the role of monocytes and high-density lipoproteins in chronic inflammation of blood vessels,as well as the current status of research on MHR and cardiovascular disease in the light of recent literature.

Serum cystatin C,monocyte/high-density lipoprotein-C ratio,and uric acid for the diagnosis of coronary heart disease and heart failure

BACKGROUND Coronary heart disease(CHD)and heart failure(HF)are the major causes of morbidity and mortality worldwide.Early and accurate diagnoses of CHD and HF are essential for optimal management and prognosis.However,conventional diagnostic methods such as electrocardiography,echocardiography,and cardiac biomarkers have certain limitations,such as low sensitivity,specificity,availability,and cost-effectiveness.Therefore,there is a need for simple,noninvasive,and reliable biomarkers to diagnose CHD and HF.AIM To investigate serum cystatin C(Cys-C),monocyte/high-density lipoprotein cholesterol ratio(MHR),and uric acid(UA)diagnostic values for CHD and HF.METHODS We enrolled 80 patients with suspected CHD or HF who were admitted to our hospital between July 2022 and July 2023.The patients were divided into CHD(n=20),HF(n=20),CHD+HF(n=20),and control groups(n=20).The serum levels of Cys-C,MHR,and UA were measured using immunonephelometry and an enzymatic method,respectively,and the diagnostic values for CHD and HF were evaluated using receiver operating characteristic(ROC)curve analysis.RESULTS Serum levels of Cys-C,MHR,and UA were significantly higher in the CHD,HF,and CHD+HF groups than those in the control group.The serum levels of Cys-C,MHR,and UA were significantly higher in the CHD+HF group than those in the CHD or HF group.The ROC curve analysis showed that serum Cys-C,MHR,and UA had good diagnostic performance for CHD and HF,with areas under the curve ranging from 0.78 to 0.93.The optimal cutoff values of serum Cys-C,MHR,and UA for diagnosing CHD,HF,and CHD+HF were 1.2 mg/L,0.9×10^(9),and 389μmol/L;1.4 mg/L,1.0×10^(9),and 449μmol/L;and 1.6 mg/L,1.1×10^(9),and 508μmol/L,respectively.CONCLUSION Serum Cys-C,MHR,and UA are useful biomarkers for diagnosing CHD and HF,and CHD+HF.These can provide information for decision-making and risk stratification in patients with CHD and HF.
