Preoperative neutrophil-to-lymphocyte ratio plus platelet-to-lymphocyte ratioin predicting survival for patients with stage Ⅰ-Ⅱgastric cancer

Background:The preoperative neutrophil-to-lymphocyte ratio(NLR) and the platelet-to-lymphocyte ratio(PLR) are associated with poor prognosis of gastric cancer.We aimed to determine whether the combination of NLR and PLR(NLR-PLR) could better predict survival of patients after curative resection for stage Ⅰ-Ⅱ gastric cancer.Methods:We collected data from the medical records of patients with stage Ⅰ-Ⅱ gastric cancer undergoing curative resection between December 2000 and November 2012 at the Sun Yat-sen Cancer Center.The preoperative NLRPLR was calculated as follows:patients with both elevated NLR(≥2.1) and PLR(≥ 120) were given a score of 2,and patients with only one or neither were given a score of 1 or 0,respectively.Results:Kaplan-Meier analysis and log-rank tests revealed significant differences in overall survival(OS) among patients with NLR-PLR scores of 0,1 and 2(P < 0.001).Multivariate analysis showed that OS was independently associated with the NLR-PLR score[hazard ratio(HR) = 1.51,95%confidence interval(CI) 1.02-2.24,P = 0.039]and TNM stage(HR = 1.36,95%CI 1.01-1.83,P= 0.041).However,other systemic inflammation-based prognostic scores,including the modified Glasgow prognostic score,the prognostic nutritional index,and the combination of platelet count and NLR,were not.In TNM stage-stratified analysis,the prognostic significance of NLR-PLR was maintained in patients with stage Ⅰ(P < 0.001) and stage Ⅱ cancers(P= 0.022).In addition,the area under the receiver operating characteristic curve for the NLR-PLR score was higher than those of other systemic inflammation-based prognostic scores(P = 0.001).Conclusion:The preoperative NLR-PLR score is a useful predictor of postoperative survival in the patients with stage l-ll gastric cancer and may help identify high-risk patients for rational therapy and timely follow-up.

Platelet-to-lymphocyte ratio in the setting of liver transplantation for hepatocellular cancer: A systematic review and meta-analysis

AIM To perform a systematic review and meta-analysis on platelet-to-lymphocyte ratio(PLR) as a risk factor for post-transplant hepatocellular cancer(HCC) recurrence. METHODS A systematic literature search was performed using PubM ed. Participants of any age and sex, who underwent liver transplantation for HCC were considered following these criteria:(1) studies comparing pre-transplant low vs high PLR values;(2) studies reporting post-transplant recurrence rates; and(3) if more than one study was reported by the same institute, only the most recent was included. The primary outcome measure was set for HCC recurrence after transplantation. RESULTS A total of 5 articles, published between 2014 and 2017, fulfilled the selection criteria. As for the quality of the reported studies, all the investigated articles presented an overall high quality. A total of 899 cases were investigated: 718 cases(80.0%) were males. Three studies coming from European countries and one from Japan presented HCV as the main cause of cirrhosis. On the opposite, one Chinese study presented a greater incidence of HBV-related cirrhotic cases. In all the studies apart one, the PLR cut-off value of 150 was reported. At meta-analysis, high PLR value was associated with a significant increase in recurrence after transplantation(OR = 3.33; 95%CI: 1.78-6.25; P < 0.001). A moderate heterogeneity was observed among the identified studies according to the Higgins I^2 statistic value.CONCLUSION Pre-transplant high PLR values are connected with an increased risk of post-operative recurrence of hepatocellular cancer. More studies are needed for better clarify the biological mechanisms of this results.

Combined preoperative platelet-to-lymphocyte ratio and serum carbohydrate antigen 19–9 level as a prognostic factor in patients with resected pancreatic cancer

Background: Carbohydrate antigen 19–9(CA19-9) is the most frequently used tumor marker and serves as a prognostic indicator in patients with pancreatic cancer(PC). The platelet-to-lymphocyte ratio(PLR) is thought to be an inflammation-related serum marker. An elevated PLR represents increased inflammatory status and is associated with poor prognosis in patients with various cancers including PC. Methods: This study involved 103 patients with a histopathological diagnosis of pancreatic ductal adenocarcinoma who underwent pancreatectomy. The patients were assessed to determine the prognostic significance of the combination of the PLR and CA19-9 level. Results: Based on the receiver operating characteristic analysis results, the patients were divided into PLR H igh(PLR ≥ 129.1) andPLRLow(PLR < 129.1) groups and into CA19-9High(CA19-9 ≥ 74.0 U/mL) and CA19-9Low(CA19-9 < 74.0 U/mL) groups. The cumulative 5-year overall survival(OS) and disease-specific survival(DSS) rates significantly differed by both the PLR(PLR H igh group: 19.5% and 22.9%;PLRLow group: 39.1% and 45.9%) and CA19-9(CA19-9 H igh group: 19.1% and 25.6%;CA19-9Low group: 41.0% and 41.0%). We then divided the patients into Groups A(PLR L ow/CA19-9Low), B(PLR Low/CA19-9High or PLRHigh/CA19-9Low), and C(PLR H igh/CA19-9High). The cumulative 5-year OS rates in Groups A, B, and C were 44.0%, 31.9%, and 11.9%, respectively( P = 0.002). The cumulative 5-year DSS rates in Groups A, B, and C were 47.7%, 36.4%, and 16.8%, respectively( P = 0.002). Multivariate analysis revealed that the combination of the PLR and CA19-9 was an independent prognostic factor in patients with resected PC. Conclusions: The combination of the PLR and CA19-9 is useful for predicting the prognosis of patients with resected PC.

Value of Platelet to Lymphocytes Ratio in Predicting Angiographic Reflow after Primary Percutaneous Coronary Intervention in STEMI Patient

Background: Acute myocardial infarction is a leading cause of death worldwide nowadays and treatment of choice is primary percutaneous coronary intervention (PCI). No reflow is a complication that increases mortality and morbidity post intervention and one of its predictors is platelet lymphocyte ratio. Aim of Study: To assess relation between admission platelet to lymphocyte ratio (PLR) and angiographic reflow after primary PCI in acute ST elevation myocardial infarction (STEMI). Patients and Methods: This is a prospective study that was conducted from May 2017 to May 2018 at Cardiology Department, Menoufia University Hospital. Sixty patients presented with ST-elevation myocardial infarction who were eligible for primary PCI were enrolled in the study. According to TIMI flow post intervention, patients were arranged into 2 groups: Group 1 (Normal Reflow) included thirty patients with post intervention TIMI flow III and Group 2 (NO Reflow) included thirty patients with post intervention TIMI flow (0, I, II). Comparison between both groups was done regarding platelet lymphocyte ratio (PLR). Result: PLR was significantly higher in patients with coronary no reflow than in patients with normal reflow with a P-value of , timing interval between onset of chest pain to time of intervention and thrombus grading was significantly higher in patients with no reflow than in patients with normal reflow. Conclusion: Pre-intervention PLR is an independent predictor of slow flow/no reflow following PPCI in patient with acute STEMI.

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.

Significances of Peripheral Inflammatory Cells and Neutrophil/Platelet-Lymphocyte Ratio in Breast Cancer after Resection

Introduction: Breast cancer had become top leading cause of death in Taiwan and endangered women’s health worldwide. Therefore, we try to invest the peripheral inflammatory cell counts and neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) from our routine practice for the predictor of prognosis of breast cancer after resection. Patients and Methods: There were 574 breast cancer patients accepted surgical resection and registered in Cancer Registry Center of our hospital. Patient’s basic profiles, peripheral neutophil, lymphocyte and platelet count were measured for study. The scales of NLR and PLR were derived from the lower and higher normal range in cell count from neutrophil, lymphocyte and platelet respectively. Therefore, the scales for NLR and PLR were ≤1.62, 1.63 - 2.57, ≥2.58 and ≤224, 225 - 253, ≥254 respectively for analysis. Results: Poor 5-yr survival rate was found if higher cell counts of neutrophil and platelet (p ≤ 0.05). Three scales of NLR were ≤1.62, 1.63 - 2.57, ≥2.58, and their 5-year survival rates were 94%, 91% and 84% respectively (p = 0.019). In the subgroup of HER-2 (negative), and 3-Negative breast patients had a higher NLR of poor prognosis. But higher PLR was found less in 3-Negative and non in 3-Positive patients (p = 0.039). The PLR was ≤224, 225 - 253, ≥254 and their 5-year survival rates were 92%, 87%, and 64% respectively (p = 0.001);Multivariate Cox regression model for predictor of breast cancer patients who have 3.39 (PLR ≥ 254) and 2.45 (NLR ≥ 2.58 ) times risk (p = 0.02 and p = 0.002) of poor prognosis respectively. Conclusion: Peripheral inflammatory cell counts are easily to take in our clinical practice and have a potential role as predictors of prognosis. We have to pay attention to the trends of peripheral inflammatory cell count and their ratio in our clinical practice where possible.

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.

Preoperative Neutrophil Lymphocyte Ratio and Platelet Lymphocyte Ratio Cannot Predict Lymph Node Metastasis and Prognosis in Patients with Early Gastric Cancer:a Single Institution Investigation in China

In the present study,we aimed at exploring the applied value of preoperative neutrophil lymphocyte ratio(NLR)and platelet lymphocyte ratio(PLR)in the prediction of lymph node metastasis(LNM)and prognosis in patients with early gastric cancer(EGC).We retrospectively analyzed a total of 248 consecutive patients who underwent curative gastrectomy to be identified T1 stage gastric adenocarcinoma between January 1,2010 and May 1,2016 in a single institution.According to median preoperative NLR and PLR value,we divided the patients into four groups:high NLR≥1.73 and low NLR〈1.73,high PLR≥117.78 and low PLR〈117.78.Furthermore,to evaluate the relationship between preoperative NLR and PLR values,we categorized patients according to cutoff preoperative NLR-PLR score of 2[high NLR(≥1.73)and high PLR(≥117.78)],1[either high NLR or high PLR],and 0[neither high NLR nor high PLR].Statistical analyses were conducted using SPSS 20.0 software.The results showed that the preoperative NLR or PLR values,lower or higher,could not predict the LNM in patients with EGC(both P=0.5440.05).The invasive depth of tumor was significantly correlated with LNM of EGC(P〈0.001).Kaplan-Meier plots illustrated that preoperative NLR and PLR values were not associated with overall survival(OS)in patients with EGC.It was concluded that the preoperative NLR and PLR may be the predictors for LNM and prognosis in patients with advanced gastric cancer;nevertheless,they cannot predict LNM and prognosis in patients with EGC.

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.

血清NLR、PLR水平与子痫前期患者早期肾损伤的关系

目的 探讨中性粒细胞/淋巴细胞比值(neutrophil to lymphocyte ratio, NLR)、血小板/淋巴细胞比值(platelet to lymphocyte ratio, PLR)与子痫前期(pre-eclampsia, PE)患者早期肾损伤的关系。方法 选取2020年1月至2022年2月本院产科收治的98例PE患者(PE组)与113例妊娠期高血压(gestational hypertension, GH)患者(GH组),另将68例在我院定期做孕检的健康孕妇作为对照组。记录3组孕妇血清NLR、PLR、肾功能指标[尿素氮(urea nitrogen, BUN)、血肌酐(serum creatinine, Scr)、胱抑素C(cystatin C,Cys-C)以及肾小球滤过率(estimate glomerular filtration rate, eGFR)]。根据是否发生肾损伤分为未发生肾损伤组(56例)与已发生肾损伤组(42例)。分析NLR、PLR与肾功能指标的关系,并进行危险因素分析以及分析NLR、PLR对PE患者发生早期肾损伤的预测价值。结果 GH组与PE组的NLR、BUN、Scr、Cys-C、24 h尿蛋白水平显著高于对照组,且PE组明显高于GH组(P<0.05);PLR、eGFR水平显著低于对照组,且PE组明显低于GH组(P<0.05)。Pearson相关性分析结果显示,NLR与BUN、Scr、Cys-C、24 h尿蛋白呈正相关,与eGFR呈负相关;PLR与BUN、Scr、Cys-C、24 h尿蛋白呈负相关,与eGFR呈正相关。多因素分析结果显示,重度PE、NLR、PLR、24 h尿蛋白、eGFR是影响PE患者发生早期肾损伤的主要危险因素(P<0.05)。受试者工作特征曲线分析发现,NLR、PLR预测PE患者发生早期肾损伤的截断值分别为2.71、103.26,曲线下面积分别为0.896、0.809,敏感度分别为93.28%、90.81%,特异度分别为80.17%、80.01%。结论 NLR、PLR水平升高与PE患者早期肾损伤有关,是PE患者发生早期肾损伤的危险因素,且对PE患者的早期肾损伤具有较高的预测价值。

Correlation of neutrophil/lymphocyte and platelet/lymphocyte ratio with visual acuity and macular thickness in age-related macular degeneration

AIM：To investigate the place of neutrophil-to-lymphocyte ratio（NLR） and platelet-to-lymphocyte ratio（PLR） in the diagnosis of and prognosis for neovascular age-related macular degeneration（AMD）. METHODS：One hundred AMD patients and 100 healthy controls were included in the study. Blood samples were obtained from the venous blood, which is used for routine analysis, and these samples were subjected to complete blood count. NLR was defined as the neutrophil count divided by the number of lymphocytes, and PLR was defined as the platelet count divided by the number of lymphocytes. RESULTS：No statistically significant difference was observed between the two groups under consideration in terms of demographic features（P〉0.05）. The average NLR in the patient group was found to be significantly higher than that in the healthy control group（P〈0.05）. The average PLR was significantly higher in the patient group as compared to the control group（P〈0.05）. As best corrected visual acuity（BCVA） increased, both NLR and PLR decreased（significant negative correlations at 49.8% and 63.0%, respectively）, whereas as central macular thickness（CMT） increased, both NLR and PLR increased（significant positive correlations at 59.3% and 70.0%, respectively）.CONCLUSION：NLR and PLR levels are higher among neovascular AMD patients as compared to healthy control group. NLR and PLR levels were found to be inversely proportional to BCVA and directly proportional to CMT.

NLR、PLR、MPVLR、PDWLR对系统性红斑狼疮和狼疮性肾炎临床预测作用的研究进展

系统性红斑狼疮(SLE)是一种可导致多种器官受累的自身免疫性疾病,其特征是持续的慢性炎症反应,狼疮性肾炎(LN)是SLE最严重的并发症之一,也是导致患者死亡的重要原因。中性粒细胞与淋巴细胞比值(NLR)、血小板计数与淋巴细胞比值(PLR)、平均血小板体积与淋巴细胞比值(MPVLR)、血小板体积分布宽度与淋巴细胞比值(PDWLR)作为常见的外周血细胞参数,是一种新兴的系统性炎症标志物,反映了机体在炎症反应与免疫失衡中的内环境变化。该综述重点介绍了NLR、PLR、MPVLR、PDWLR对SLE和LN的预测作用,总结对比了NLR与PLR、MPVLR与PDWLR对SLE预测的灵敏度,为评估SLE疾病活动度和LN肾脏受累程度提供参考价值。目前对于这些炎症标志物的研究仍处于早期研究阶段,仍缺少各炎症标志物之间联合应用的研究以及多中心、大样本、前瞻性研究进行验证。
