Role of lymphocyte-to-monocyte ratio as a predictive marker for diabetic coronary artery disease: A cross-sectional study

BACKGROUND The lymphocyte to monocyte ratio(LMR)is considered a marker of systemic inflammation in cardiovascular disease and acts as predictor of mortality in coronary artery disease.AIM To investigate the predictive role of LMR in diabetic coronary artery disease patients.METHODS This cross-sectional study was conducted at tertiary care super-specialty hospital at New Delhi,India.A total of 200 angiography-proven coronary artery disease(CAD)patients were enrolled and grouped into two categories:Group I[CAD patients with type 2 diabetes mellitus(T2DM)and glycated hemoglobin(HbA1c)levels≥6.5%],and Group II(CAD patients without T2DM and HbA1c levels<6.5%).Serum lipoproteins,HbA1c,and complete blood count of enrolled patients were analyzed using fully automatic analyzers.RESULTS The logistic regression analysis showed an odds ratio of 1.48(95%CI:1.28-1.72,P<0.05)for diabetic coronary artery disease patients(Group I)in unadjusted model.After adjusting for age,gender,diet,smoking,and hypertension history,the odds ratio increased to 1.49(95%CI:1.29-1.74,P<0.01)in close association with LMR.Further adjustment for high cholesterol and triglycerides yielded the same odds ratio of 1.49(95%CI:1.27-1.75,P<0.01).Receiver operating characteristic curve analysis revealed 74%sensitivity,64%specificity,and 0.74 area under the curve(95%CI:0.67-0.80,P<0.001),suggesting moderate predictive accuracy for diabetic CAD patients.CONCLUSION LMR showed positive association with diabetic coronary artery disease,with moderate predictive accuracy.These findings have implications for improving CAD management in diabetics,necessitating further research and targeted interventions.

Analysis of the Peripheral Blood Helper T-Cell 17- Cell Level and Monocyte/Lymphocyte Ratio for Colorectal Cancer Prognosis Prediction

Objective: To investigate the value of peripheral blood helper T cell 17 cell level and monocyte/lymphocyte ratio to predict the prognosis of colorectal cancer patients. Methods: 74 colorectal cancer patients who attended Hospital 960 from January 2021 to January 2022 were retrospectively analyzed. Clinical data of the patients were collected, including gender, age, and histologic type. Immunohistochemical indexes such as Th17 cell level and monocyte/ lymphocyte ratio in the peripheral blood of patients were also collected. The prognosis of patients after treatment, as well as peripheral blood Th17 and MLR levels, were observed and analyzed. Results: After follow-up after treatment, in the final 74 patients, the prognosis was good in 32 patients, accounting for 43.24%, and the prognosis was bad in 42 patients, accounting for 56.76%. There were no significant differences between the average age and tumor diameters of the good prognosis and poor prognosis groups (P > 0.05). However, the TNM staging, intervention taken, differentiation degree, presence of distant metastasis, presence of lymph node metastasis, Th17 level, and MLR level are significantly different between the two groups (P < 0.05). Conclusion: Peripheral blood Th17 and MLR have predictive value for the prognosis of colorectal cancer patients, and high levels of peripheral blood Th17 and MLR imply poor prognosis. The detection of peripheral blood Th17 and MLR levels is simple and convenient and can be used as indicators to provide a reference for the prognostic assessment of colorectal cancer patients.

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.

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.

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 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.

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 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.

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.

Feasibility of lymphocyte-to-monocyte ratio in predicting no-reflow phenomenon in ST-elevation myocardial infarction patients undergoing primary percutaneous coronary intervention

Background The no-reflow phenomenon is correlated with adverse effects on short-term and long-term outcomes of ST-elevation myocardial infarction(STEMI) in patients undergoing primary percutaneous coronary intervention(PCI). The lymphocyte-to-monocyte ratio(LMR) is a novel inflammatory marker which is associated with slow coronary flow. We aimed to investigate the predictive value of LMR for no-reflow phenomenon in patients with STEMI undergoing primary PCI. Methods A total of 1350 STEMI patients were enrolled in this study from January 2014 to January 2018. Blood samples were obtained at initial admission for analysis of LMR.The univariate and multivariate logistic regression analysis was performed to study the relationship between LMR and no-reflow phenomenon. Results All the 156 patients among the study population suffered from no-reflow phenomenon during the procedure. The LMR level was significantly lower in patients with no-reflow(1.6 ±1.0 vs. 3.25 ± 1.8, P<0.001). Multivariate logistic regression analysis showed that LMR was independently associated with no-reflow post primary PCI in STEMI patients.(OR 2.356, 95% CI 1.201-5.945;P=0.030). The area under the ROC curve for the LMR was 0.757 [95% confidence interval(CI) 0.686-0.828, P<0.001]. Conclusions LMR at admission could serve as a biomarker for no-reflow phenomenon in patients undertaken primary PCI for STEMI.[S Chin J Cardiol 2019;20(4):228-235]

目的探讨中性粒细胞-淋巴细胞比值(NLR)、单核细胞-淋巴细胞比值(MLR)、血小板-淋巴细胞比值(PLR)与抗N-甲基-D-天冬氨酸受体(NMDAR)脑炎的关系。方法选择2014年6月至2021年6月在河北医科大学第二医院神经内科确诊为抗NMDAR脑炎的患者42例作为抗NMDAR脑炎组,同时选取性别、年龄与抗NMDAR脑炎组匹配的健康人群作为健康对照组,收集患者的临床资料,计算NLR、MLR及PLR,根据疾病高峰时改良Rankin量表(mRS)评分评估抗NMDAR脑炎患者病情,并将其分为轻度组和重度组,将其与健康对照组42例进行比较,并比较轻度组和重度组患者的年龄、外周血细胞计数、NLR、MLR及PLR的差异。结果抗NMDAR脑炎组患者的白细胞、中性粒细胞、单核细胞、NLR、MLR及PLR较健康对照组比较显著升高(P<0.05),血小板、淋巴细胞较健康对照组显著降低(P<0.05)。重度抗NMDAR脑炎组患者的白细胞、中性粒细胞、NLR及PLR水平显著高于轻度抗NMDAR脑炎组(P<0.05),淋巴细胞显著低于轻度抗NMDAR脑炎组(P<0.05)。NLR水平升高与重度抗NMDAR脑炎有显著相关性(P<0.05)。结论NLR是重度抗NMDAR脑炎的独立危险因素。

淋巴细胞/单核细胞比值及其动态变化与PD-1抑制剂治疗晚期非小细胞肺癌的疗效分析

目的:探讨PD-1抑制剂治疗前外周血淋巴细胞和单核细胞比值(lymphocyte-to-monocytes ratios,LMR)及治疗后的动态变化与PD-1抑制剂治疗晚期非小细胞肺癌患者(non-small cell lung cancer,NSCLC)疗效及预后的关系。方法:回顾性分析芜湖市第二人民医院肿瘤内科、肿瘤放疗科及肿瘤介入科自2019年6月至2022年7月收治的83例晚期NSCLC患者的临床病例资料。收集所有患者治疗前及治疗后的血常规LMR数值,根据ROC曲线计算临界值,并将LMR分为治疗前和治疗后高低两组。分析比较各组患者的客观缓解率(ORR)、疾病控制率(DCR),以及无进展生存期(progression-free survival,PFS)、总生存期(overall survival,OS)的差异,分析LMR值及治疗后的动态变化对PD-1抑制剂治疗NSCLC患者疗效及预后的价值。结果:根据ROC曲线计算LMR临界值为1.8,将LMR分为基线低LMR组(LMRB/S<1.8)、高LMR组(LMRB/S≥1.8)及治疗后低LMR组(LMRafter<1.8)、治疗后高LMR组(LMR_(after)≥1.8)。治疗前高LMRB/S组免疫治疗后的ORR和DCR均高于低LMRB/S组(P=0.037;P=0.0025)。治疗前低LMRB/S患者中,在治疗后LMRafter≥1.8组的DCR优于LMR_(after)<1.8组(P=0.005)。治疗前高LMR患者中,治疗后LMR_(after)≥1.8组的DCR优于LMR_(after)<1.8组(P=0.034)。Kaplan-Meier分析显示,治疗前高LMRB/S组的PFS、OS均比低LMRB/S组延长;且在治疗前低LMRB/S组中,治疗后LMRafter≥1.8的患者PFS、OS均比LMR_(after)<1.8的患者延长(P=0.047;P=0.007)。多因素Cox回归模型分析显示,治疗前高LMRB/S值是影响NSCLC患者PFS和OS的独立危险因素(P=0.006;P=0.033)。结论:免疫治疗前患者高LMR值可能提高PD-1抑制剂的疗效,改善患者预后,延长生存时间;且治疗后LMR值的升高可能会增加治疗前低LMR患者的疗效,改善患者的预后。
