Pre‐treatment neutrophil/lymphocyte ratio and platelet/lymphocyte ratio are prognostic of progression in early stage classical Hodgkin lymphoma

To determine whether pre‐treatment neutrophil/lymphocyte (NLR) or platelet/lymphocyte ratios (PLR) are predictive for progression in early‐stage classical Hodgkin lymphoma (cHL), we derived NLR and PLR values for 338 stage I/II cHL patients and appropriate cut‐off point values to define progression. Two‐year freedom from progression (FFP) for patients with NLR ≥6·4 was 82·2% vs. 95·7% with NLR <6·4 (P < 0·001). Similarly, 2‐year FFP was 84·3% for patients with PLR ≥266·2 vs. 96·1% with PLR <266·2 (P = 0·003). On univariate analysis, both NLR and PLR were significantly associated with worse FFP (P = 0·001). On multivariate analysis, PLR remained a significant, independent prognostic factor (P < 0·001).

Prognostic role of neutrophil-lymphocyte ratio in operable esophageal squamous cell carcinoma

AIM: To determine the prognostic significance of preoperative serum neutrophil-lymphocyte ratio(NLR) in esophageal squamous cell carcinoma(ESCC).METHODS: Data from 371 eligible patients with ESCC who had undergone surgery with curative intent at our institution between October 2000 and May 2007 were retrospectively recruited for analysis. The cutoff value of NLR was 3.0 as determined by the receiver operating characteristic curve, which discriminated between survival and death; the area under the curve was 0.709, and the sensitivity and specificity were 66.1% and 69.1%, respectively, at the cutoff point. The correlation between the NLR and clinicopathological characteristics was analyzed using a χ2 test. The prognostic influence of the NLR and other clinicopathological factors on cancer-specific survival(CSS) and recurrence-free survival(RFS) was studied using the Kaplan-Meier method. To evaluate the independent prognostic value of NLR, multivariate Cox regression models were applied.RESULTS:The median age of the patients was 57.0years,and 276/371(74.4%)patients were male.The NLR was≤3.0 in 80.1%(297/371)of the patients,and the remaining 19.9%(74/371)had an NLR3.0.Median postoperative follow-up was 66.0 mo[interquartile range(IQR):49.0-76.0 mo],with a follow-up rate of 94%.Follow-up was not significantly different between patients with an NLR≤and3.0(63.13±1.64 vs 61.52±3.66,P=0.711).However,higher preoperative serum NLR was associated with significantly increased risks of higher pathological tumor status(P=0.007).A significant,independent association between high preoperative serum NLR and poor clinical outcome was identified in a multivariate analysis for CSS(HR=1.591;P=0.007)and RFS(HR=1.525;P=0.013).Moreover,when patients were stratified by pathological tumor-node-metastasis(TNM)staging,the adverse effects of preoperative serum NLR on CSS(HR=2.294;P=0.008)and RFS(HR=2.273;P=0.008)were greatest in those patients with stageⅢA disease.CONCLUSION:Preoperative serum NLR is a useful prognostic marker to complement TNM staging for operable ESCC patients,particularly in patients with stageⅢA disease.     

Validation and clinical usefulness of pre- and postoperative systemic inflammatory parameters as prognostic markers in patients with potentially resectable pancreatic cancer

BackgroundSeveral preoperative systemic inflammatory parameters, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), prognostic nutritional index (PNI), and Glasgow prognostic score, have been reported to be associated with the prognosis of solid tumors. In this study, we compared pre- and postoperative hematological inflammatory parameters and validated their prognostic significance in pancreatic cancer patients who underwent surgical resection.MethodsClinical records from 211 consecutive pancreatic cancer patients who underwent surgical resection at our institution were retrospectively analyzed. The optimal cutoff values of hematological inflammatory parameters, including lymphocyte count, NLR, PLR, LMR, and PNI, were determined by time-dependent receiver-operating characteristic analysis.ResultsThe postoperative neutrophil count and serum albumin level were significantly decreased in patients who underwent pancreatoduodenectomy (PD group) and in those who underwent distal pancreatectomy (DP group) compared to the levels at baseline. The postoperative lymphocyte count, monocyte count, and platelet count were significantly increased in the DP group compared to those at baseline. As a result, the postoperative NLR and PNI significantly decreased in both groups. The multivariate analysis identified intraoperative peritoneal washing cytology, administration of adjuvant therapy, tumor size, extrapancreatic nerve plexus invasion, and preoperative PLR as independent prognostic factors for overall survival.ConclusionsSystemic inflammatory responses were altered after pancreatic resection in pancreatic cancer patients. Preoperative PLR may be a useful prognostic marker in pancreatic cancer patients undergoing surgical resection.     

Preoperative level of serum amyloid A is superior to C‐reactive protein in the prognosis of esophageal squamous cell carcinoma

Preoperative elevations in the levels of serum amyloid A (SAA) or C‐reactive protein (CRP) have been reported to be prognostic indicators in several malignancies. The aim of this study is to evaluate the serum levels of SAA and CRP in the prognosis of esophageal squamous cell carcinoma (ESCC). In total, 252 patients with ESCC who had undergone surgery with curative‐intent were retrospectively recruited. The specificity, sensitivity, and prognostic value of SAA or CRP levels were measured as the area under the receiver operating characteristic (ROC) curve (AUC). The clinical value of SAA and CRP levels as prognostic indicators was evaluated using Cox's proportional hazards model. The 1‐, 3‐, and 5‐year overall survival (OS) rates for the entire cohort of patients with ESCC were 71.0%, 61.0%, and 43.0%, respectively. The correlation between the levels of SAA and CRP was significant (r² = 0. 685, P < 0.001). The ROC analysis showed that the levels of CRP were associated with a significantly lower overall accuracy than were the SAA levels (AUC, 0.615 vs. 0.880; P < 0.001). For the complete cohort, the median OS was 52.0 months longer in patients with low preoperative serum levels of SAA (72.0 months) compared with patients who had high SAA levels (20.0 months, P < 0.001). The median OS among patients with low CRP levels was also longer compared with the patients who had high CRP levels (72.0 vs. 51.0 months, respectively; P < 0.001). Subgroup analyses showed that the preoperative elevated levels of SAA could find significant differences in OS for stage I, stage II, and stage III (P < 0.001, P = 0.001, and P < 0.001, respectively), whereas the increased levels of CRP could only find a difference in OS for stage II cancers. After a multivariate analysis, preoperative elevated level of SAA was found to be an independently and significant prognostic factor (P < 0.001). Our study indicates that the preoperative levels of SAA and CRP can act as prognostic factors, and that elevated levels of these proteins are associated with negative effects on the survival of patients with ESCC. SAA showed a higher prognostic value than CRP in both cohort and subgroup analysis.     

Pretherapy neutrophil to lymphocyte ratio and platelet to lymphocyte ratio do not predict survival in resectable pancreatic cancer

Background

Pretherapy serum neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) have both been identified as prognostic in pancreatic ductal adenocarcinoma (PDAC). The aim of this study was to identify the prognostic implication of pretherapy NLR and PLR in patients with resectable PDAC.

Prechemotherapy neutrophil : lymphocyte ratio is superior to the platelet : lymphocyte ratio as a prognostic indicator for locally advanced esophageal squamous cell cancer treated with neoadjuvant chemotherapy

The study aimed to evaluate the prognostic significance of prechemotherapy neutrophil to lymphocyte ratio and platelet to lymphocyte ratio, and preoperative neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in locally advanced esophageal squamous cell cancer. We analyzed retrospectively locally advanced esophageal squamous cell cancer patients who had received neoadjuvant chemotherapy before undergoing a radical esophagectomy between 2009 and 2012. Neutrophil to lymphocyte ratio and platelet to lymphocyte ratio before chemotherapy and before the surgery were calculated. Univariate analyses showed that prechemotherapy neutrophil to lymphocyte ratio >5 (P = 0.048, hazard ratio = 2.86; 95% confidence interval: 1.01–8.12) and prechemotherapy platelet to lymphocyte ratio >130 (P = 0.025, hazard ratio = 5.50; 95% confidence interval: 1.23–24.55) were associated significantly with overall survival (OS), and prechemotherapy platelet to lymphocyte ratio >130 (P = 0.026, hazard ratio = 3.18; 95% confidence interval: 1.15–8.85) was associated significantly with progression‐free survival. However, only prechemotherapy neutrophil to lymphocyte ratio >5 (P = 0.024, hazard ratio = 3.50; 95% confidence interval: 1.18–10.40) remained significantly associated with OS in multivariate analyses. Neither preoperative neutrophil to lymphocyte ratio nor platelet to lymphocyte ratio was associated with OS or progression‐free survival. The prechemotherapy neutrophil to lymphocyte ratio >5 to preoperative neutrophil to lymphocyte ratio ≤5 group showed significantly worse OS than the prechemotherapy neutrophil to lymphocyte ratio ≤5 to preoperative neutrophil to lymphocyte ratio ≤5 group (P = 0.050). The prechemotherapy platelet to lymphocyte ratio >130 to preoperative platelet to lymphocyte ratio ≤130 group (P = 0.016) and platelet to lymphocyte ratio >130 to preoperative platelet to lymphocyte ratio >130 group (P = 0.042) showed significantly worse OS than the prechemotherapy platelet to lymphocyte ratio ≤30 to preoperative platelet to lymphocyte ratio ≤130 group. In conclusions, prechemotherapy neutrophil to lymphocyte ratio is an independent prognostic factor for OS in patients with advanced esophageal squamous cell cancer treated with neoadjuvant chemotherapy, and, as an adverse prognostic predictor, increased prechemotherapy neutrophil to lymphocyte ratio is superior to platelet to lymphocyte ratio. Maintaining a low neutrophil to lymphocyte ratio and platelet to lymphocyte ratio throughout treatment is a predictor of better OS.     

Negative Impact of Preoperative Platelet-Lymphocyte Ratio on Outcome After Hepatic Resection for Intrahepatic Cholangiocarcinoma

The elevated platelet-to-lymphocyte ratio (PLR), determined using an easy blood test based on platelet and lymphocyte counts, is reported to be a predictor of poor survival in patients with several cancers. The prognostic role of preoperative PLR in patients with intrahepatic cholangiocarcinoma (ICC) has, until now, been rarely investigated. The purpose of our study was to evaluate the prognostic significance of PLR in a large cohort of ICC patients after hepatic resection.We obtained data from 322 consecutive nonmetastatic ICC patients who underwent hepatectomy without preoperative therapy between 2005 and 2011. Clinicopathological parameters, including PLR, were evaluated. Overall survival (OS) and recurrence-free survival (RFS) were assessed using the Kaplan–Meier method. Using multivariate Cox regression models, the independent prognostic value of preoperative PLR was determined.Our results showed that PLR represents an independent adverse prognostic factor for OS and RFS in ICC patients using univariate and multivariate analyses. The optimal PLR cutoff value was 123 using receiver operating curve analyses. The 5-year OS and RFS rates after hepatectomy were 30.3% and 28.9% for the group with PLR 123 greater, compared with 46.2% and 39.4% for the group with PLR less than 123 (P = 0.0058 and 0.0153, respectively). In addition, high PLR values were associated with tumor size (P = 0.020).Our results suggest that preoperative PLR might represent a novel independent prognostic factor for OS and RFS in ICC patients with hepatic resection.     

Neutrophil to lymphocyte and platelet to lymphocyte ratio in patients with dipper versus non-dipper hypertension

Background: Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are associated with worse outcome in various diseases. Non-dipping blood pressure pattern is associated with higher cardiovascular mortality. The aim of this study was to explore the association between NLR and PLR in patients with dipper versus non-dipper hypertension.

Methods: The study included 166 patients with hypertension. Eighty-three patients (40 male, mean age: 49.1?±?10.5 years) had dipper hypertension, while 83 patients (41 male, mean age: 52.3?±?12.7 years) had non-dipper hypertension.

Results: Baseline demographic characteristics were similar in both groups. Patients with non-dipper hypertension had significantly higher NLR compared to dipper hypertension (2.3?±?0.9 versus 1.8?±?0.5, p?p?=?0.001). In univariate analysis, hyperlipidemia, smoking, presence of diabetes, PLR more than 107 and NLR more than 1.89 were among predictors of dipper and non-dipper status. In logistic regression analyses, only hyperlipidemia (odds ratio: 2.96, CI: 1.22–7.13) and PLR more than 107 (odds ratio: 2.62, CI: 1.13–6.06) were independent predictors of dipper and non-dipper status. A PLR of 107 or higher predicted non-dipper status with a sensitivity of 66.3% and specificity of 68.7%.

Conclusion: We demonstrated that patients with non-dipper hypertension had significantly higher NLR and PLR compared to dipper hypertension, which has not been reported previously. Moreover PLR more than 107 but not NLR was independent predictor of non-dipper status.     

The association between the neutrophil to lymphocyte ratio and in-hospital mortality among sepsis patients: A prospective study

The Neutrophil to lymphocyte ratio (NLR) was shown to be associated with disease severity, poor prognosis and increased mortality in sepsis. However, the association between NLR and sepsis prognosis remains controversial.Our study aims to prospectively examine the prognostic ability of NLR in predicting in-hospital mortality among sepsis patients and determine the optimal cutoff of NLR that can most accurately predict in-hospital mortality in sepsis patients. This study was a prospective cohort study that included adult sepsis patients that presented to the emergency department of a tertiary care center between September 2018 and February 2021.Receiver operating characteristic curve was used to determine the optimal cutoff of the neutrophil to lymphocyte ratio that predicts in-hospital mortality. Patients were divided into 2 groups: above and below the optimal cutoff. Stepwise logistic regression was performed to assess the magnitude of the association between NLR and in-hospital mortality.A total of 865 patients were included in the study. The optimal cutoff for the neutrophil to lymphocyte ratio that predicts in-hospital mortality was found to be 14.20 with a sensitivity of 44.8% and a specificity of 65.3% (with PPV = 0.27 and NPV = 0.80). The area under the curve for the ratio was 0.552 with a 95% confidence intervals = [0.504–0.599] with a P value = .03. Patients that have a NLR above the cutoff were less likely to survive with time compared to patients below the cutoff based on the Kaplan–Meier curves. In the stepwise logistic regression, the optimal neutrophil to lymphocyte ratio cutoff was not associated with in-hospital mortality (odds ratios = 1.451, 95% confidence intervals = [0.927–2.270], P = .103).In conclusion the optimal cutoff of the NLR that predicts in-hospital mortality among sepsis patients was 14.20. There was no association between the NLR and in-hospital mortality in sepsis patients after adjusting for confounders. Further studies with a larger sample size should be done to determine the optimal NLR cutoff and its prognostic role in septic patients (in-hospital mortality and other clinically significant outcomes).     

Platelet to lymphocyte ratio as a novel prognostic tool for gallbladder carcinoma

AIM: To preliminarily investigate the prognostic significance of the platelet to lymphocyte ratio (PLR) in patients with gallbladder carcinoma (GBC).METHODS: Clinical data of 316 surgical GBC patients were analyzed retrospectively, and preoperative serum platelet and lymphocyte counts were used to calculate the PLR. The optimal cut-off value of the PLR for detecting death was determined by the receiver operating characteristic (ROC) curve. The primary outcome was overall survival, which was estimated by the Kaplan-Meier method. The log-rank test was used to compare the differences in survival. Then, we conducted multivariate Cox analysis to assess the independent effect of the PLR on the survival of GBC patients.RESULTS: For the PLR, the area under the ROC curve was 0.620 (95%CI: 0.542-0.698, P = 0.040) in detecting death. The cut-off value for the PLR was determined to be 117.7, with 73.6% sensitivity and 53.2% specificity. The PLR was found to be significantly positively correlated with CA125 serum level, tumor-node-metastasis (TNM) stage, and tumor differentiation. Univariate analysis identified carcinoembryonic antigen (CEA), CA125 and CA199 levels, PLR, TNM stage, and the degree of differentiation as significant prognostic factors for GBC when they were expressed as binary data. Multivariate analysis showed that CA125 > 35 U/mL, CA199 > 39 U/mL, PLR ≥ 117.7, and TNM stage IV were independently associated with poor survival in GBC. When expressed as a continuous variable, the PLR was still an independent predictor for survival, with a hazard ratio of 1.018 (95%CI: 1.001-1.037 per 10-unit increase, P = 0.043).CONCLUSION: The PLR could be used as a simple, inexpensive, and valuable tool for predicting the prognosis of GBC patients.     

急性冠状动脉综合征患者血清中性粒细胞/淋巴细胞比值、血小板/淋巴细胞比值水平对冠状动脉病变程度及院内主要不良心血管事件的评估价值

目的探讨急性冠状动脉综合征(ACS)患者中性粒细胞/淋巴细胞比值(NLR)、血小板/淋巴细胞比值(PLR)与冠状动脉狭窄程度及院内主要不良心血管事件(MACE)发生的关系。方法收集2018年4月至2020年4月于新疆医科大学第一附属医院初次行冠状动脉造影ACS患者(426例)的临床基本资料、实验室参数,根据住院MACE情况,将纳入的患者分为MACE组(104例)和无MACE组(322例)。根据Gensini评分的三分位数,将患者分为三组:低Gensini组(≤34分,143例),中Gensini组(34~58分,142例),高Gensini组(>58分,141例),使用t检验、方差分析、卡方检验、非参数Mann-Whitney U检验、Kruskal-Wallish H检验、logistic回归分析和受试者工作特性曲线等统计方法对数据进行分析。结果MACE组NLR[4.48(2.42,7.47)比2.82(1.79,4.70),P<0.001]和PLR[133.21(92.88,190.25)比101.03(75.33,134.01),P<0.001]显著高于无MACE组,差异有统计学意义。在基于Gensini评分分组的三组中,低Gensini组、中Gensini组、高Gensini组NLR[3.59(1.56,3.58)比3.47(1.94,5.73)比3.71(2.13,6.21),P<0.001]、PLR[93.98(66.03,127.94)比110.90(88.26,140.79)比120.37(84.58,174.54),P<0.001]比较,差异均有统计学意义。logistic回归分析显示,NLR(OR 1.189,95%CI 1.003~1.409,P=0.046;OR 1.102,95%CI 1.005~1.208,P=0.039)、PLR(OR 1.008,95%CI 1.002~1.014,P=0.021;OR 1.004,95%CI 1.002~1.009,P=0.042)是院内MACE和高Gensini评分的独立危险因素。NLR预测院内MACE发生的截断值为4.516,敏感度为50.00%,特异度为74.53%,曲线下面积(AUC)为0.633(95%CI 0.585~0.679,P<0.001);PLR预测院内MACE发生的截断值为153.103,敏感度为45.19%,特异度为84.78%,AUC为0.666(95%CI 0.619~0.711,P<0.001)。NLR预测高Gensini评分(>58分)的截断值为3.802,敏感度为49.62%,特异度为66.44%(AUC=0.600,95%CI 0.552~0.647,P<0.001);PLR预测高Gensini评分的截断值为153.543,敏感度为37.40%,特异度为84.75%(AUC=0.616,95%CI 0.567~0.662,P<0.001)。结论NLR、PLR作为一种新的炎症标志物,与ACS患者院内MACE的发生和冠状动脉狭窄的严重程度有显著的独立相关性。NLR、PLR作为一种容易获得且价格便宜的炎症指标,可作为有效的炎症标志物广泛应用于鉴别高危患者,从而有助于指导个体化治疗以改善ACS预后。     

Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) were useful markers in assessment of inflammatory response and disease activity in SLE patients

Objective: Although there have been extensive investigations on neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and mean platelet volume (MPV) in many diseases, their roles in systemic lupus erythematosus (SLE) remain unclear. The purpose of the present study was to evaluate NLR, PLR, and MPV levels in adult SLE patients and explore their clinical significance.

Methods: A retrospective study involving 154 adult SLE patients and 151 healthy controls was performed. All clinical characteristics of the SLE patients were extracted from their medical records. NLR, PLR, and MPV levels between SLE patients and healthy controls were compared, and correlations between these indexes and clinical characteristics were analyzed.

Results: Increased NLR, PLR, and MPV were observed in SLE patients. NLR was positively correlated with C-reaction protein (r?=?0.509, p?<?0.01), erythrocyte sedimentation rate (r?=?0.610, p?<?0.01), and SLE Disease Activity Index (SLEDAI) scores (r?=?0.471, p?<?0.01). PLR was positively correlated with SLEDAI scores (r?=?0.44, p?<?0.01). SLE patients with nephritis had higher NLR and PLR levels than those without nephritis (p?<?0.01, p?=?0.03). In addition, an NLR level of 2.065 was determined as predictive cut-off value of SLE (sensitivity 74.7%, specificity 77.5%, AUC?=?0.828). Multiple regression analysis suggested that NLR was independently associated with SLE disease activity.

Conclusions: NLR and PLR could reflect inflammatory response and disease activity in SLE patients.     

Prognostic value of preoperative P-CRP in patients with osteosarcoma: A retrospective study of 101 cases

This study aimed to investigate the value of the product of peripheral blood platelet and serum C-reactive protein (P-CRP), an inflammatory indicator, for the prognosis of patients with osteosarcoma. Patients with osteosarcoma who were diagnosed and treated at the First Affiliated Hospital of Guangxi Medical University, China, between January 2012 and December 2019 were included in this retrospective study. Receiver operating characteristic curves were used to calculate the optimal cut-off values for inflammatory indicators such as P-CRP, the C-reactive protein/albumin ratio (CRP/Alb), the neutrophil–lymphocyte ratio (NLR), and the platelet–lymphocyte ratio (PLR) in the peripheral blood of patients before treatment. Based on the cut-off values, the patients were divided into high P-CRP and low P-CRP groups, high CRP/Alb and low CRP/Alb groups, high NLR and low NLR groups, and high NLR and low NLR groups; the Kaplan–Meier method was used to compare the overall survival (OS) rates and OS times of the above groups. Univariate and multivariate Cox regression models were used to analyze the effects of various factors on the prognosis of osteosarcoma and to determine the independent influencing factors. The Kaplan–Meier survival analysis results suggested that the OS rate of the high P-CRP group was significantly lower than that of the low P-CRP group (14.0% vs 67.2%, P < .001). The univariate analysis results suggested that tumor volume, tumor stage, NLR, PLR, P-CRP and CRP/Alb were factors that affected the prognosis of patients with osteosarcoma, and the differences were statistically significant (P < .05). The multivariate analysis results showed that tumor volume (hazard ratio [HR] = 1.061; 95% CI, 1.001–1.125; P = .046) and preoperative P-CRP (HR, 1.037; 95% CI, 1.024–1.050; P < .01) were independent prognostic factors affecting the OS rate after osteosarcoma surgery. The results of our study showed that P-CRP is a novel and promising prognostic indicator for patients with osteosarcoma. The higher the P-CRP level in the peripheral blood of patients is before treatment, the worse the prognosis might be.

Prognostic value of preoperative mean corpuscular volume in esophageal squamous cell carcinoma

AIM: To evaluate whether preoperative mean corpuscular volume (MCV) is a prognostic indicator in patients with resectable esophageal squamous cell carcinoma (ESCC). METHODS: A total of 298 consecutive, prospectively enrolled patients with histologically diagnosed ESCC who underwent surgery with curative intent from 2001 to 2011 were retrospectively evaluated. Patients were excluded if they had previous malignant disease, distant metastasis at the time of primary treatment, a history of neoadjuvant treatment, had undergone nonradical resection, or had died of a non-tumor-associated cause. Survival status was verified in September 2011. Pathological staging was performed based on the 2010 American Joint Committee on Cancer criteria. Preoperative MCV was obtained from blood counts performed routinely within 7 d prior to surgery. Receiver operating characteristic (ROC) curve analysis was used to determine a cutoff for preoperative MCV. RESULTS: The 298 patients consisted of 230 males and 68 females, with a median follow-up of 30.1 mo. ROC analysis showed an optimal cutoff for preoperative MCV of 95.6 fl. Fifty-nine patients (19.8%) had high (> 95.6 fl) and 239 (80.2%) had low (≤ 95.6 fl) preoperative MCV. Preoperative MCV was significantly associated with gender (P=0.003), body mass index (P=0.017), and preoperative red blood cell count (P<0.001). The predicted 1-, 3and 5-year overall survival (OS) rates were 72%, 60% and 52%, respectively. Median OS was significantly longer in patients with low than with high preoperative MCV (27.5 mo vs 19.4 mo, P<0.001). Multivariate analysis showed that advanced pT (P=0.018) and pN (P<0.001) stages, upper thoracic location (P=0.010), lower preoperative albumin concentration (P=0.002), and high preoperative MCV (P=0.001) were negative prognostic factors in patients with ESCC. Preoperative MCV also stratified OS in patients with T3, N1-N3, G2-G3 and stage Ⅲ tumors. CONCLUSION: Preoperative MCV is a prognostic factor in patients with ESCC.     

Neutrophil to lymphocyte and platelet to lymphocyte ratios in systemic lupus erythematosus: Relation with disease activity and lupus nephritis

ObjectivesTo investigate the role of neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) as activity markers in systemic lupus erythematosus (SLE) without nephritis and lupus nephritis (LN) patients.Patients and methodsThis study included 60 SLE patients with LN, 60 SLE patients without renal involvement and 30 healthy controls. We analyzed correlations between NLR and PLR and both disease activity and renal affection.ResultsThe NLR of SLE patients was much higher than those of the controls. Both ratios showed significantly increased values in SLE patients with active disease. NLR and PLR were positively correlated with SLEDAI, ESR, and CRP and negatively correlated with C4. SLE patients with LN had higher levels of NLR than those without nephritis. NLR showed positive correlations with BUN, serum urea, serum creatinine and 24 h urinary protein. We found NLR to be related to anti-ds-DNA level and renal biopsy classes. While PLR was related only to anti ds-DNA. The best NLR to predict SLE active disease was 2.2 and the best PLR cut-off value was 132.9.ConclusionNLR and PLR are useful inflammatory markers to evaluate disease activity in SLE patients. Also, NLR could reflect renal involvement in SLE patients and is associated with the different classes of its histological staging.

MGC patients on firstline modified docetaxel/cisplatinum/5-fluorourasil [mDCF; docetaxel 60 mg/m² (days 1–5), cisplatin 60 mg/m² (day 1), 5FU 600 mg/m² (days 1–5), q3w] were evaluated retrospectively. The cutoff values were 160 for PLR and 2.5 for NLR. Progression-free survival (PFS) and overall survival (OS) were estimated for group I (PLR >160), group II (PLR ≤ 160), group III (NLR ≥ 2.5), group IV (NLR < 2.5), group V (PLR > 160 and NLR ≥ 2.5), group VI (PLR ≤ 160 and NLR <2.5), and group VII [VIIa (PLR > 160 and NLR < 2.5) and VIIb (PLR ≤160 and NLR ≥ 2.5)].

Results:

One hundred and nine MGC patients were evaluated for basal hematological parameters and survival analysis, retrospectively. Most of the patients were male in their fifties with grade III adenocarcinoma (62.9%) and liver metastasis (46.7%). Patients with PLR > 160 and/or NLR ≥ 2.5 had significantly shorter PFS and OS (P = 0.04, 0.01, 0.019, and P = 0.003, 0.002, 0.000, respectively).

Conclusion:

High PLR (> 160) and/or NLR (≥ 2.5) seem to be poor prognostic factors in MGC.     

Neutrophil–lymphocyte ratio: a novel predictor for short‐term prognosis in acute‐on‐chronic hepatitis B liver failure

Acute‐on‐chronic hepatitis B liver failure (ACHBLF) has a poor prognosis in patients with hepatitis B virus infection. The role of the neutrophil–lymphocyte ratio (NLR), which reflects the inflammatory status of the patient before treatment, has never been studied in this setting. To investigate the predictive value of NLR in patients with ACHBLF, a retrospective cohort with 216 patients and a prospective validation cohort with 73 patients were recruited. Multivariate analyses showed that total bilirubin (TBIL), NLR, age and model for end‐stage liver disease (MELD) score had prognostic significance for survival. Both NLR (0.781) and MELD score (0.744) had higher ROC curves, which differed significantly from those for age (0.615) and TBIL (0.691), but not from each other (P = 0.94). NLR ≤2.36 predicted lower mortality (with 91.6% sensitivity and 86.0% negative predictive value), and NLR >6.12 was a warning sign for higher mortality risk (with 90.1% specificity and 80.3% positive predictive value). These results demonstrated that pretreatment NLR was associated with the prognosis of patients with ACHBLF, and elevated NLR predicted poor outcome within 8 weeks. We suggest that NLR cut‐offs of ≤2.36 and >6.12 are powerful markers for predicting mortality in ACHBLF.     

The Predictive Value of Platelet/Lymphocyte Ratio in Hemodialysis Patients With Erythropoietin Resistance

The most important cause of anemia in CKD is relative deficiency of erythropoietin (EPO) secretion from the diseased kidney and EPO therapy has become the standard treatment for anemia of CKD. However, some patients do not respond well to erythropoiesis stimulating agent (ESA), so‐called ESA resistance. One of the most important causes of ESA resistance is chronic inflammation in hemodialysis (HD) patients. ESA hyporesponsiveness index (EHRI), calculated as the weekly dose of EPO divided by kilograms of body weight divided by the hemoglobin level, and has been considered useful to assess the EPO resistance. Neutrophil/lymphocyte (NLR) ratio and platelet/lymphocyte ratio (PLR) were also found to be associated with inflammation in HD patients. However, the relationship between NLR, PLR and EHRI has not been investigated before. HD patients underwent medical history taking, physical examination, calculation of dialysis adequacy and biochemical analysis and calculation of EHRI. Logarithmically converted EHRI (logEHRI) was correlated only with hemoglobin (r –0.381, P < 0.0001) and PLR (r = 0.227, P = 0.021) but not with NLR. Comparison of PLR among 25th, 50th and 75th percentile of EHRI showed that PLR levels increased going from the 25th to 75^th percentile (P = 0.032). Posthoc analysis revealed that 25–75th percentile (P = 0.014) and 50–75th percentile (P = 0.033) were different with respect to PLR. In linear regression analysis, PLR (standardized β = 0.296, confidence interval: 0.000–0.001, P = 0.003) was independently associated with logEHRI. We found that PLR was independently associated with EHRI in HD patients. PLR, which is quite a simple and cheap method, may guide clinicians for detecting EPO resistance.
