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 NLR>3.0.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≤and>3.0(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.展开更多

Prognostic markers such as interleukin-6, S-100 protein and high sensitivity C reactive protein have been studied as predictors of adverse outcomes after return of spontaneous circulation(ROSC); however; these variables are not routine laboratory tests and incur additional cost making them difficult to incorporate and less attractive in assessing patient's prognosis. The neutrophil-lymphocyte ratio(NLR) is a marker of adverse prognosis for many cardiovascular conditions and certain types of cancers and sepsis. We hypothesize that an elevated NLR is associated with poor outcomes including mortality at discharge in patients with IHCA.AIM To determine the prognostic significance of NLR in patients suffering IHCA who achieve ROSC.METHODS A retrospective study was performed on all patients who had IHCA with the advanced cardiac life support protocol administered in a large urban community United States hospital over a one-year period. Patients were divided into two groups based on their NLR value(NLR < 4.5 or NLR ≥ 4.5). This cutpoint was derived from receiving operator characteristic curve analysis(area under the curve = 0.66) and provided 73% positive predictive value, 82% sensitivity and42% specificity for predicting in-hospital death after IHCA. The primary outcome was death or discharge at 30 d, whichever came first.RESULTS We reviewed 153 patients with a mean age of 66.1 ± 16.3 years; 48% were female.In-hospital mortality occurred in 65%. The median NLR in survivors was 4.9(range 0.6-46.5) compared with 8.9(0.28-96) in non-survivors(P = 0.001). A multivariable logistic regression model demonstrated that an NLR above 4.55[odds ratio(OR) = 5.20, confidence interval(CI): 1.5-18.3, P = 0.01], older age(OR= 1.03, CI: 1.00-1.07, P = 0.05), and elevated serum lactate level(OR = 1.20, CI:1.03-1.40, P = 0.02) were independent predictors of death.CONCLUSION An NLR ≥ 4.5 may be a useful marker of increased risk of death in patients with IHCA.展开更多

Methods: We identified the cases of 114 consecutive patients who underwent the surgery at our Hospital between January 2006 and December 2012 by using the multivariate analysis, the Cox proportional-hazard regression model. Results: Multivariate analysis for the predictors of survival showed metastatic lesion resection [hazard ratio (HR) = 3.2, 95% confidence interval (CI) 1.6 - 6.6;p = 0.007] and only primary lesion resection (HR = 1.9, 95% CI 1.1 - 4.0;p = 0.045) remained independently significant prognostic factors. Therefore, we divided in 3 groups, 1) metastatic lesion resection group with primary lesion resection (n = 52 in the Met/Prim lesion group), 2) primary lesion resection without metastatic lesion resection (n = 38 in the Primary lesion group) and 3) palliative operation (n = 24 in the Palliative group). Age was the only independent risk factor in the Met/Prim lesion group. In the Primary lesion group, Neutrophil lymphocyte ratio (NLR) > 5, elevated Alanine aminotransferase and patients without chemotherapy were correlated with poor survival. In the Palliative group, NLR > 5 and patients who could not be treated with chemotherapy remained independent predictors of worse survival. Conclusions: NLR is not only simple and convenient for classification of patients, but also one of the important predictors of mortality for stage IV incurable CRC patients.展开更多

文摘AIM:To determine whether an elevated neutrophillymphocyte ratio(NLR)is negatively associated with tumor recurrence in patients with hepatitis B virus(HBV)-related hepatocellular carcinoma(HCC)after liver transplantation(LT),and to determine the optimal predictive NLR cut-off value.METHODS:The data of HCC patients who had undergone LT came from the China Liver Transplant Registry database.We collected data from 326 liver cancer patients who had undergone LT at our medical center.We divided the patients into groups based on their NLRs(3,4 or 5).We then compared the clinicopathological data and long-time survival between these groups.Meanwhile,we used receiver operating characteristic analysis to determine the optimal NLR cut-off.RESULTS:Of 280 HCC patients included in this study,263 were HBV positive.Patients with an NLR<3 and patients with an NLR≥3 but<4 showed no significant differences in overall survival(OS)(P=0.212)or disease-free survival(DFS)(P=0.601).Patients with an NLR≥4 but<5 and patients with an NLR≥5also showed no significant differences in OS(P=0.208)or DFS(P=0.618).The 1-,3-and 5-year OS rates of patients with an NLR<4 vs an NLR≥4 were 87.8%,63.8%and 61.5%vs 73.9%,36.7%and 30.3%,respectively(P<0.001).The 1-,3-and 5-year DFS rates of patients with an NLR<4 vs NLR≥4 were 83.9%,62.9%and 60.7%vs 64.9%,30.1%and 30.1%,respectively(P<0.001).Univariate and multivariate analyses demonstrated that three factors,including NLR≥4(P=0.002),were significant predictors of tumor recurrence in HCC patients after LT.CONCLUSION:A preoperative elevated NLR significantly increased the risk for tumor recurrence in HCC patients after LT.
文摘BACKGROUND Gastric cancer(GC)is one of the most common malignant tumors in the world.Although in recent years tremendous progress has been made in its early detection,the postoperative overall survival(OS)of GC patients remains extremely low.A number of studies have shown that age,to varying degrees,affects the prognosis of patients with GC.Therefore,this study retrospectively analyzed the clinical and pathologic data of patients with GC to explore the differences in the clinical characteristics and prognostic factors in different age groups.AIM To explore the difference in clinicopathological characteristics and prognostic factors in GC patients in different age groups.METHODS In this retrospective study,we analyzed 1037 GC patients admitted to Renji Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from May 2010 to January 2013.The patients were divided into two groups based on age:Younger group(less than 70 years old)and older group(no less than 70 years old).In the younger group,we subdivided the patients in two subgroups by a cutoff value of 45 years.The clinical features and prognostic factors were analyzed in both groups.Subsequently,we retrieved studies that evaluated the predictive role of neutrophil-lymphocyte ratio(NLR)by searching two medical databases,PubMed and EMBASE,to conduct a meta-analysis.Random-effects model was used to pool the data.RESULTS In the retrospective study,the mean OS time of the younger group(64.7 mo)was significantly longer than that of the older group(48.1 mo)(P<0.001).Among patients under 70 years of age,hospitalization time,tumor–node–metastasis(TNM)stage,vascular invasion,and preoperative low pre-albumin were independently associated with OS(P<0.005).In patients aged 70 years and above,TNM stage,esophageal invasion,histological type,and preoperative NLR were independent factors for OS(P<0.05).The OS of these older patients was also significantly shorter(P<0.05).In the meta-analysis,19 retrieved studies included a total of 8312 patients,among whom 3558 had elevated NLR values.The results showed that high NLR value was a risk factor for the prognosis of GC(P<0.01).CONCLUSION The OS of elderly patients is significantly worse than that of younger patients.There are significant differences in clinicopathological characteristics and prognostic factors between younger and older patients.NLR is a convenient,inexpensive,and reproducible marker that can be used as an important predictor of the prognosis of GC.
文摘BACKGROUND In-hospital cardiac arrest(IHCA) portends a poor prognosis and survival to discharge rate. Prognostic markers such as interleukin-6, S-100 protein and high sensitivity C reactive protein have been studied as predictors of adverse outcomes after return of spontaneous circulation(ROSC); however; these variables are not routine laboratory tests and incur additional cost making them difficult to incorporate and less attractive in assessing patient's prognosis. The neutrophil-lymphocyte ratio(NLR) is a marker of adverse prognosis for many cardiovascular conditions and certain types of cancers and sepsis. We hypothesize that an elevated NLR is associated with poor outcomes including mortality at discharge in patients with IHCA.AIM To determine the prognostic significance of NLR in patients suffering IHCA who achieve ROSC.METHODS A retrospective study was performed on all patients who had IHCA with the advanced cardiac life support protocol administered in a large urban community United States hospital over a one-year period. Patients were divided into two groups based on their NLR value(NLR < 4.5 or NLR ≥ 4.5). This cutpoint was derived from receiving operator characteristic curve analysis(area under the curve = 0.66) and provided 73% positive predictive value, 82% sensitivity and42% specificity for predicting in-hospital death after IHCA. The primary outcome was death or discharge at 30 d, whichever came first.RESULTS We reviewed 153 patients with a mean age of 66.1 ± 16.3 years; 48% were female.In-hospital mortality occurred in 65%. The median NLR in survivors was 4.9(range 0.6-46.5) compared with 8.9(0.28-96) in non-survivors(P = 0.001). A multivariable logistic regression model demonstrated that an NLR above 4.55[odds ratio(OR) = 5.20, confidence interval(CI): 1.5-18.3, P = 0.01], older age(OR= 1.03, CI: 1.00-1.07, P = 0.05), and elevated serum lactate level(OR = 1.20, CI:1.03-1.40, P = 0.02) were independent predictors of death.CONCLUSION An NLR ≥ 4.5 may be a useful marker of increased risk of death in patients with IHCA.
文摘BACKGROUND Early prediction of response to percutaneous catheter drainage(PCD)of necrotic collections in acute pancreatitis(AP)using simple and objective tests is critical as it may determine patient prognosis.The role of white blood cell(WBC)count and neutrophil-lymphocyte ratio(NLR)has not been assessed as a tool of early prediction of PCD success and is the focus of this study.AIM To assess the value of WBC and NLR in predicting response to PCD in AP.METHODS This retrospective study comprised consecutive patients with AP who underwent PCD between June 2018 and December 2019.Severity and fluid collections were classified according to the revised Atlanta classification and organ failure was defined according to the modified Marshall Score.WBC and NLR were monitored 24 h prior PCD(WBC-0/NLR-0)and 24 h(WBC-1/NLR-1),48 h(WBC-2/NLR-2)and 72 h(WBC-3/NLR-3)after PCD.NLR was calculated by dividing the number of neutrophils by the number of lymphocytes.The association of success of PCD(defined as survival without the need for surgery)with WBC and NLR was assessed.The trend of WBC and NLR was also assessed post PCD.RESULTS One hundred fifty-five patients[median age 40±13.6(SD),64.5%males,53.5%severe AP]were included in the final analysis.PCD was done for acute necrotic collection in 99(63.8%)patients and walled-off necrosis in 56(36.1%)patients.Median pain to PCD interval was 24±69.89 d.PCD was successful in 109 patients(group 1)and 46 patients(group 2)who failed to respond.There was no significant difference in the baseline characteristics between the two groups except the severity of AP and frequency of organ failure.Both WBC and NLR showed an overall decreasing trend.There was a significant difference between WBC-0 and WBC-1(P=0.0001).WBC-1 and NLR-1 were significantly different between the two groups(P=0.048 and 0.003,respectively).The area under the curve of WBC-1 and NLR-1 for predicting the success of PCD was 0.602 and 0.682,respectively.At a cut-off value of 9.87 for NLR-1,the sensitivity and specificity for predicting the success of PCD were calculated to be 75%and 65.4%respectively.CONCLUSION WBC and NLR can be used as simple tests for predicting response to PCD in patients with acute necrotizing pancreatitis.
文摘Objectives: Our aim is investigating the predictive potential of these available and convenient laboratory dates in stage IV colorectal cancer (CRC) patients. Methods: We identified the cases of 114 consecutive patients who underwent the surgery at our Hospital between January 2006 and December 2012 by using the multivariate analysis, the Cox proportional-hazard regression model. Results: Multivariate analysis for the predictors of survival showed metastatic lesion resection [hazard ratio (HR) = 3.2, 95% confidence interval (CI) 1.6 - 6.6;p = 0.007] and only primary lesion resection (HR = 1.9, 95% CI 1.1 - 4.0;p = 0.045) remained independently significant prognostic factors. Therefore, we divided in 3 groups, 1) metastatic lesion resection group with primary lesion resection (n = 52 in the Met/Prim lesion group), 2) primary lesion resection without metastatic lesion resection (n = 38 in the Primary lesion group) and 3) palliative operation (n = 24 in the Palliative group). Age was the only independent risk factor in the Met/Prim lesion group. In the Primary lesion group, Neutrophil lymphocyte ratio (NLR) > 5, elevated Alanine aminotransferase and patients without chemotherapy were correlated with poor survival. In the Palliative group, NLR > 5 and patients who could not be treated with chemotherapy remained independent predictors of worse survival. Conclusions: NLR is not only simple and convenient for classification of patients, but also one of the important predictors of mortality for stage IV incurable CRC patients.
文摘Renal cell carcinoma(RCC) is one of the ten most common malignancies.The prognosis of RCC is poor when the disease is in advanced stages,with five-year survival of less than 10%.However current assessment approaches are limited in their ability to prognosticate and guide therapeutic decision-making.Cellular-mediated inflammatory response is increasingly being recognised to have an important role in carcinogenesis of RCC.Various inflammatory markers have been found to identify patients with RCC at high risk of recurrence and predict survival.Neutrophil-lymphocyte ratio(NLR) is a simple and inexpensive inflammatory marker that has been shown to be of value in the assessment of patients with RCC.An elevated pretreatment NLR has been found to be associated with reduced overall survival,recurrence-free survival and progress-free survival and risk of recurrence in localized RCC.In addition,lower pretreatment NLR has been demonstrated to be associated with better clinical response to systemic therapy including vascular endothelial growth factor inhibitors,among patients with metastatic RCC.However,NLR has not been found to differentiate whether small renal masses of less than 40 mm are benign or malignant.Further research is needed to determine the cut-offs for NLR to predict different clinical outcomes and how post-treatment NLR can be used.In addition,more work is also needed to evaluate combining NLR with other biomarkers in a model to predict patients' clinical outcome or response to treatment for RCC.
文摘Pregnancy associated diseases/disorders are associated with significant maternal and neonatal morbidities and mortalities.Devising/validating cost effective and easily accessible predictive,diagnostic and risk stratification markers are critical to the management and improved outcome in these diseases.Inflammation forms the backbone of most of the routinely encountered maternal complications of pregnancy.Hematological markers can be considered as a direct reflection of the systemic inflammatory milieu.Recently,the neutrophil lymphocyte ratio has been explored for its potential to assess the severity of inflammation and thus the severity of the underlying disorder.The neutrophil-lymphocyte ratio has gained scientific attention as a potential prognostic/predictive marker of acute as well as chronic inflammatory diseases including gynecological and reproductive disorders.This present study reviews the mechanistic role of neutrophils and lymphocytes in fueling or propagating the inflammatory cascades in the three most common maternal complications of pregnancy and the evidence of clinical importance of the neutrophil to lymphocyte ratio in predicting,diagnosing,and prognosticating pregnancy-associated complications.

文摘BACKGROUND The neutrophil-lymphocyte ratio(NLR)is often used to predict a poor prognosis in patients with tumors.This study investigated the preoperative peripheral blood NLR in predicting postoperative survival(POS)in patients with multiple myeloma bone disease(MMBD).AIM To evaluate whether NLR can be used to predict the prognosis of MMBD patients after surgery.METHODS The clinical data of 82 MMBD patients who underwent surgical treatments in Beijing Chao-yang Hospital were collected.The NLR was obtained from the absolute number of neutrophils and lymphocytes,calculated by the number of neutrophils and divided by the number of lymphocytes.The peripheral blood lymphocyte percentage was used as the major marker to analyze the change in characteristics of the immune statuses of multiple myeloma patients.RESULTS The NLR cut-off values of NLR≥3 patients and NLR≥4 patients were significantly correlated with POS.The 3-and 5-year cumulative survival rates of the high NLR group(NLR≥3 patients)were 19.1%and 0.0%,respectively,which were lower than those of the low NLR group(NLR<3 patients)(67.2%and 48.3%)(P=0.000).In the high NLR group,POS(14.86±14.28)was significantly shorter than that in the low NLR group(32.68±21.76).Univariate analysis showed that the lymphocyte percentage 1 wk after the operation(19.33±9.08)was significantly lower than that before the operation(25.72±11.02).Survival analysis showed that postoperative chemotherapy,preoperative performance status and preoperative peripheral blood NLR≥3 were independent risk factors for POS.CONCLUSION The preoperative peripheral blood NLR can predict POS in MMBD patients.MMBD patients with a high preoperative NLR(NLR≥3)showed poor prognosis.
