Compared with patients who showed a preoperative NLR < 2.81 and postoperative increase, patients who showed preoperative NLR ≥ 2.81 and postoperative decrease had worse survival(DFS, P < 0.001; OS, P < 0.001). Among patients with preoperative NLR ≥ 2.81, survival was significantly higher among those showing a postoperative decrease in NLR than among those showing an increase(DFS, P < 0.001; OS, P < 0.001). When elevated, alpha-fetoprotein(AFP) provided no prognostic information, and so preoperative NLR ≥ 2.81 may be a good complementary indicator of poor OS whenever AFP levels are low or high.CONCLUSION: Preoperative NLR ≥ 2.81 may be an indicator of poor DFS and OS in patients with HCC undergoing surgery. Preoperative NLR ≥ 2.81 may be a good complementary indicator of poor OS when elevated AFP levels provide no prognostic information.展开更多

We sought to make this comparison. Methods A total of 1355 elderly patients with CHF were analyzed. A multivariate logistic regression model was used to analyze the variables associated with atrial fibrillation （AF）. Cox regression analysis was used to assess the multivariable rela- tionship between the N/L ratio, NT-proBNP level, and subsequent major cardiovascular events （MCE）. Results In the multiple logistic regression analysis, the N/L ratio was demonstrated as a risk factor for AF in elderly patients with CHF [odds ratio （OR）： 1.079, 95% confi- dence interval （CI）： 1.027-1.134, P = 0.003]. The median follow-up period was 18 months. In a multivariable model using tertiles of both variables, the highest tertile of the N/L ratio was significantly associated with MCE [hazard ratio （HR）： 1.407, 95% CI： 1.098-1.802, P = 0.007] compared with the lowest tertile. Similarly, the highest NT-proBNP tertile was also significantly associated with MCE （HR： 1.461, 95% CI： 1.104-1.934, P- 0.008）. Conclusions In elderly patients with CHF, the N/L ratio is one of the important risk factors for AF and it is an inexpensive and readily available marker with similar independent prognostic power to NT-proBNP. The risk of MCE increases 1.407-fold when the N/L ratio is elevated to the highest tertile.展开更多

Between July 2014 and July 2016, 107 patients with PDAC were enrolled for CTC evaluation. CTC enumeration and classification were correlated with patient clinicopathological features and outcomes.RESULTS CTCs were detected in 78.5% of PDAC patients. The number of total CTCs ranged from 0 to 26 across all 107 patients, with a median value of six. CTC status correlated with lymph node metastasis, TNM stage, distant metastasis, blood lymphocyte counts, and neutrophil-to-lymphocyte ratio(NLR). Kaplan-Meier survival analysis showed that patients with ≥ 6 total CTCs had significantly decreased overall survival and progression-free survival compared with patients with < 6 total CTCs. The presence of M-CTCs was positively correlated with TNM stage(P < 0.01) and distant metastasis(P < 0.01). Additionally, lymphocyte counts and NLR in patients without CTCs were significantly different from those in patients testing positive for each CTC subpopulation(P < 0.01).CONCLUSION Classifying CTCs by EMT markers helps to identify the more aggressive CTC subpopulations and provides useful evidence for determining a suitable clinical approach.展开更多

Although the TNM stage is importan...Several parameters for predicting survival in patients with colorectal cancer have been identified, including the performance status, age, gender and tumor-nodemetastasis(TNM) stage. Although the TNM stage is important and useful for predicting the prognosis and determining the appropriate treatment, it is well known that the survival time varies widely, even in patients with the same stage of disease. Therefore, the identification of new parameters capable of more precisely predicting patient survival is needed to help select the optimal treatment, especially in patients in the advanced stage of disease. Although the TNM stage reflects the tumor characteristics, cancer progression and survival are not determined solely based on the local characteristics of the tumor, but also the host systemic immune/inflammatory response. Therefore, using a combination of parameters that reflect both tumor characteristics and the host systemic inflammatory status is thought to be important for accurately predicting patient survival.展开更多

METHODS: Data from 82 patients who underwent combination chemotherapy with gemcitabine and erlotinib for PC from 2011 to 2014 were collected retrospectively. Data that included the neutrophil-to-lymphocyte ratio(NLR), the platelet-to-lymphocyte ratio, and the C-reactive protein(CRP)-to-albumin(CRP/Alb) ratio were analyzed. Kaplan-Meier curves, and univariate and multivariate Cox proportional hazards regression analyses were used to identify the prognostic factors associated with progression-free survival(PFS) and overall survival(OS). RESULTS: The univariate analysis demonstrated the prognostic value of the NLR(P = 0.049) and the CRP/Alb ratio(P = 0.047) in relation to PFS, and a positiverelationship between an increase in inflammation-based markers and a poor prognosis in relation to OS. The multivariate analysis determined that an increased NLR(hazard ratio = 2.76, 95%CI: 1.33-5.75, P = 0.007) is an independent prognostic factor for poor OS. There was no association between the PLR and the patients' prognoses in those who had received chemotherapy that comprised gemcitabine and erlotinib in combination. The Kaplan-Meier method and the log-rank test determined significantly worse outcomes in relation to PFS and OS in patients with an NLR > 5 or a CRP/Alb ratio > 5.CONCLUSION: Systemic inflammation-based markers, including increases in the NLR and the CRP/Alb ratio, may be useful for predicting PC prognoses.展开更多

METHODS: With the aim of identifying the studies related to NLR, a search was conducted on http://www.ncbi.nlm.nih.gov/pubmed by utilizing the key words "neutrophil lymphocyte ratio, ocular diseases, and eye diseases" up to February 2018. All of the original articles were assessed according to date of publications, countries, clinics and topics. Studies about ocular inflammatory diseases were evaluated according to their qualifications, review methods and results. RESULTS: A total of 4473 publications, including original research articles and reviews were screened. The number of publications was shown a regular logarithmic increase over the years. The majority of studies were performed by clinics in Turkey and many of these publications were performed by oncology and cardiology clinics. A total of 75 publications were identified to be about ocular diseases. CONCLUSION: Elevated NLR as a cheap, reproducible, and readily available marker could be used as a diagnostic and/or prognostic marker in ocular diseases.展开更多

According to the characteristic of endometriosis, we analyzed the new biomarker neutrophil-to-lymphocyte ratio （NLR） and the combination of NLR and serum CA-125 to investigate their diagnostic value for identifying stages III and IV endometdosis. Methods The values of serum CA-125 and routine blood tests were collected from 197 patients with endometriosis, 102 with benign tumors and 112 healthy individuals. We investigated the sensitivity and specificity of NLR and its combination with serum-CA-125 for diagnosing stages III and IV endometriosis by using receiver operating characteristic （ROC）. Results The mean values of NLR, the combination of serum CA-125 and NLR （combination） of the groups with stages III and IV endometriosis were significantly higher than the other two groups. Serum CA-125, NLR, and the combined biomarkers could significantly discriminate the stages Ill and IV endometriosis group from the other two groups （P〈0.05）. NLR shows a lower sensitivity of 57.9% and specificity of 65.2% with a cutoff value at 1.82. And the combination of biomarkers has the highest AUC of 0.949 with a sensitivity of 86.8% and specificity of 92.0% at the cutoff value of 44.40. In addition, for patients with negative CA-125, 55.36% and 53.57% of the patients were able to be diagnosed with endometriosis by using NLR alone and the combination of biomarkers. Conclusion For diagnosing stages III and IV endometriosis, the neutrophil-to-lymphocyte ratio is a better adjuvant to serum CA-125, and the neutrophil-to-lymphocyte ratio is valuable in diagnosing stages III and IV endometriosis for patients with negative serum CA-125.展开更多

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.展开更多

The demographics, laboratory analyses, and histopathology data were analyzed.RESULTS Overall survival(OS) and disease-free survival(DFS) were determined in the patients with a high(> 2.9) and low(≤ 2.9) NLR. The median OS and DFS duration in the high NLR group were significantly shorter than those in the low NLR group(OS: 6.2 mo vs 15.7 mo, respectively, P = 0.007; DFS: 2.2 mo vs 3.7 mo, respectively, P = 0.039). An NLR > 2.9 was identified as an independent predictor of a poor prognosis of OS(P = 0.034, HR = 1.866; 95%CI: 1.048-3.322) in uni-and multivariate analyses. Moreover, there was a significantly positive correlation between the NLR and the Child-Pugh score(r = 0.276, P = 0.015) and the maximum diameter of the tumor(r = 0.435, P < 0.001). Additionally, the NLR could enhance the prognostic predictive power of the CLIP score for DFS in these patients. CONCLUSION The preoperative NLR is a prognostic predictor after hepatectomy for HCC patients with PVTT/HVTT. NLR > 2.9 indicates poorer OS and DFS.展开更多

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.展开更多

文摘Objective:Cancer-associated inflammation and coagulation cascades play vital roles in cancer progression and survival.In this study,we investigated the significance of the combination of preoperative fibrinogen and the neutrophil-to-lymphocyte ratio(NLR)in predicting the survival of patients with non-small cell lung cancer(NSCLC).Methods:We retrospectively enrolled 589 patients with NSCLC who underwent surgery.The univariate and multivariate Cox survival analyses were used to evaluate the prognostic indicators,including the combination of fibrinogen and NLR(F-NLR).The cut-off values for fibrinogen,NLR,and clinical laboratory variables were defined by the receiver operating characteristic(ROC)curve analysis.According to the ROC curve,the recommended cut-off values for fibrinogen and the NLR were 3.48 g/L and 2.30,respectively.Patients with both a high NLR(≥2.30)and hyperfibrinogenemia(≥3.48 g/L)were given a score of 2,whereas those with one or neither were scored as 1 or 0,respectively.Results:Our results showed that F-NLR was an independent prognostic indicator for disease-free survival(DFS)[hazard ratio(HR),1.466;95%confidence interval(CI),1.243–1.730;P<0.001]and overall survival(OS)(HR,1.512;95%CI,1.283–1.783;P<0.001).The five-year OS rates were 66.1%,53.5%,and 33.3%for the F-NLR=0,F-NLR=1,and F-NLR=2,respectively(P<0.001).Correspondingly,their five-year DFS rates were 62.2%,50.3%,and 30.4%,respectively(P<0.001).In the subgroup analyses of the pathological stages,the F-NLR level was significantly correlated with DFS and OS in stage I and IIIA cancers.Conclusions:Preoperative F-NLR score can be used as a valuable prognostic marker for patients with resectable early-stage NSCLC.

文摘AIM: To investigate whether an elevated preoperative neutrophil-to-lymphocyte ratio(NLR) can predict poor survival in patients with hepatocellular carcinoma(HCC).METHODS: We retrospectively reviewed 526 patients with HCC who underwent surgery between 2004 and 2011.RESULTS: Preoperative NLR ≥ 2.81 was an independent predictor of poor disease-free survival(DFS, P < 0.001) and overall survival(OS, P = 0.044). Compared with patients who showed a preoperative NLR < 2.81 and postoperative increase, patients who showed preoperative NLR ≥ 2.81 and postoperative decrease had worse survival(DFS, P < 0.001; OS, P < 0.001). Among patients with preoperative NLR ≥ 2.81, survival was significantly higher among those showing a postoperative decrease in NLR than among those showing an increase(DFS, P < 0.001; OS, P < 0.001). When elevated, alpha-fetoprotein(AFP) provided no prognostic information, and so preoperative NLR ≥ 2.81 may be a good complementary indicator of poor OS whenever AFP levels are low or high.CONCLUSION: Preoperative NLR ≥ 2.81 may be an indicator of poor DFS and OS in patients with HCC undergoing surgery. Preoperative NLR ≥ 2.81 may be a good complementary indicator of poor OS when elevated AFP levels provide no prognostic information.
文摘Background The neutrophil-to-lymphocyte （N/L） ratio has been associated with poor prognosis in patients with heart failure, but it has not been compared with N-terminal pro-brain natriuretic peptide （NT-proBNP） in elderly patients with chronic heart failure （CHF）. We sought to make this comparison. Methods A total of 1355 elderly patients with CHF were analyzed. A multivariate logistic regression model was used to analyze the variables associated with atrial fibrillation （AF）. Cox regression analysis was used to assess the multivariable rela- tionship between the N/L ratio, NT-proBNP level, and subsequent major cardiovascular events （MCE）. Results In the multiple logistic regression analysis, the N/L ratio was demonstrated as a risk factor for AF in elderly patients with CHF [odds ratio （OR）： 1.079, 95% confi- dence interval （CI）： 1.027-1.134, P = 0.003]. The median follow-up period was 18 months. In a multivariable model using tertiles of both variables, the highest tertile of the N/L ratio was significantly associated with MCE [hazard ratio （HR）： 1.407, 95% CI： 1.098-1.802, P = 0.007] compared with the lowest tertile. Similarly, the highest NT-proBNP tertile was also significantly associated with MCE （HR： 1.461, 95% CI： 1.104-1.934, P- 0.008）. Conclusions In elderly patients with CHF, the N/L ratio is one of the important risk factors for AF and it is an inexpensive and readily available marker with similar independent prognostic power to NT-proBNP. The risk of MCE increases 1.407-fold when the N/L ratio is elevated to the highest tertile.
文摘Background:Gastric cancer is the 2 nd most common cause of cancer-related deaths,and the morbidity rate after surgery is reported to be as high as 46%.The estimation of possible complications,morbidity,and mortality and the ability to specify patients at high risk have become substantial for an intimate follow-up and for proper management in the intensive care unit.This study aimed to determine the prognostic value of the preoperative platelet-tolymphocyte ratio(PLR)and neutrophil-to-lymphocyte ratio(NLR)and their relations with clinical outcomes and complications after gastrectomy for gastric cancer.Methods:This single-center,retrospective cohort study evaluated the data of 292 patients who underwent gastrectomy with curative intent between January 2015 and June 2018 in a tertiary state hospital in Ankara,Turkey.A receiver operating characteristic curve was generated to evaluate the ability of laboratory values to predict clinically relevant postoperative complications.The area under the curve was computed to compare the predictive power of the NLR and PLR.Then,the cutoff points were selected as the stratifying values for the PLR and NLR.Results:The area under the curve values of the PLR(0.60,95%CI 0.542–0.657)and NLR(0.556,95%CI 0.497–0.614)were larger than those of the other preoperative laboratory values.For the PLR,the diagnostic sensitivity and specificity were 50.00%and 72.22%,respectively,whereas for the NLR,the diagnostic sensitivity and specificity were 37.50%and 80.16%,respectively.The PLR was related to morbidity,whereas the relation of the NLR with mortality was more prominent.This study demonstrated that the PLR and NLR may predict mortality and morbidity via the ClavienDindo classification in gastric cancer patients.The variable was grade≥3 in the Clavien-Dindo classification,including complications requiring surgical or endoscopic interventions,life-threatening complications,and death.Both the PLR and NLR differed significantly according to Clavien-Dindo grade≥3.In this analysis,the PLR wa
文摘AIM To evaluate the clinical properties of three subpopulations of circulating tumor cells(CTCs) undergoing epithelial-mesenchymal transition(EMT) in pancreatic ductal adenocarcinoma(PDAC) patients.METHODS We identified CTCs for expression of the epithelial cell marker cytokeratin or epithelial cell adhesion molecule(EpCAM)(E-CTC), the mesenchymal cell markers vimentin and twist(M-CTC), or both(E/M-CTC) using the CanPatrol system. Between July 2014 and July 2016, 107 patients with PDAC were enrolled for CTC evaluation. CTC enumeration and classification were correlated with patient clinicopathological features and outcomes.RESULTS CTCs were detected in 78.5% of PDAC patients. The number of total CTCs ranged from 0 to 26 across all 107 patients, with a median value of six. CTC status correlated with lymph node metastasis, TNM stage, distant metastasis, blood lymphocyte counts, and neutrophil-to-lymphocyte ratio(NLR). Kaplan-Meier survival analysis showed that patients with ≥ 6 total CTCs had significantly decreased overall survival and progression-free survival compared with patients with < 6 total CTCs. The presence of M-CTCs was positively correlated with TNM stage(P < 0.01) and distant metastasis(P < 0.01). Additionally, lymphocyte counts and NLR in patients without CTCs were significantly different from those in patients testing positive for each CTC subpopulation(P < 0.01).CONCLUSION Classifying CTCs by EMT markers helps to identify the more aggressive CTC subpopulations and provides useful evidence for determining a suitable clinical approach.
文摘Several parameters for predicting survival in patients with colorectal cancer have been identified, including the performance status, age, gender and tumor-nodemetastasis(TNM) stage. Although the TNM stage is important and useful for predicting the prognosis and determining the appropriate treatment, it is well known that the survival time varies widely, even in patients with the same stage of disease. Therefore, the identification of new parameters capable of more precisely predicting patient survival is needed to help select the optimal treatment, especially in patients in the advanced stage of disease. Although the TNM stage reflects the tumor characteristics, cancer progression and survival are not determined solely based on the local characteristics of the tumor, but also the host systemic immune/inflammatory response. Therefore, using a combination of parameters that reflect both tumor characteristics and the host systemic inflammatory status is thought to be important for accurately predicting patient survival.
文摘BACKGROUND The inverse association between systemic immune-inammation index(SII)and overall survival in tumors has been studied.AIM To evaluate the hematological indexes for assessing the activity of ulcerative colitis(UC).METHODS In this case-control study,172 UC patients and healthy participants were included.Comparisons were made among groups of white blood cells,hemoglobin,platelets,neutrophils,lymphocytes,monocytes,SII,neutrophil-tolymphocyte ratio(NLR),and platelet-to-lymphocyte ratio(PLR).The relationship with hematological inflammation was verified by Spearman correlation analyses.The efficiency of SII,NLR,and PLR for distinguishing between UC and severe disease status was assessed by the receiver operator curve and logistic regression analyses.RESULTS The values of SII,NLR,and PLR were higher in UC patients than in controls(P<0.001)and were positively correlated with the Mayo endoscopic score,extent,Degree of Ulcerative Colitis Burden of Luminal Inflammation(DUBLIN)score,and Ulcerative Colitis Endoscopic Index of Severity(UCEIS).The cut-off NLR value of 562.22 predicted UC with a sensitivity of 79.65%and a specificity of 76.16%.Logistic regression analysis revealed that patients with SII and NLR levels above the median had a significantly higher risk of UC(P<0.05).Risk factors independently associated with DUBLIN≥3 included SII≥1776.80[odds ratio(OR)=11.53,P=0.027]and NLR value of 2.67-4.23(OR=2.96,P=0.047)on multivariate analysis.Compared with the first quartile,SII≥1776.80 was an independent predictor of UCEIS≥5(OR=18.46,P=0.012).CONCLUSION SII has a certain value in confirming UC and identifying its activity.

文摘AIM: To evaluate the value of systemic inflammationbased markers as prognostic factors for advanced pancreatic cancer(PC). METHODS: Data from 82 patients who underwent combination chemotherapy with gemcitabine and erlotinib for PC from 2011 to 2014 were collected retrospectively. Data that included the neutrophil-to-lymphocyte ratio(NLR), the platelet-to-lymphocyte ratio, and the C-reactive protein(CRP)-to-albumin(CRP/Alb) ratio were analyzed. Kaplan-Meier curves, and univariate and multivariate Cox proportional hazards regression analyses were used to identify the prognostic factors associated with progression-free survival(PFS) and overall survival(OS). RESULTS: The univariate analysis demonstrated the prognostic value of the NLR(P = 0.049) and the CRP/Alb ratio(P = 0.047) in relation to PFS, and a positiverelationship between an increase in inflammation-based markers and a poor prognosis in relation to OS. The multivariate analysis determined that an increased NLR(hazard ratio = 2.76, 95%CI: 1.33-5.75, P = 0.007) is an independent prognostic factor for poor OS. There was no association between the PLR and the patients' prognoses in those who had received chemotherapy that comprised gemcitabine and erlotinib in combination. The Kaplan-Meier method and the log-rank test determined significantly worse outcomes in relation to PFS and OS in patients with an NLR > 5 or a CRP/Alb ratio > 5.CONCLUSION: Systemic inflammation-based markers, including increases in the NLR and the CRP/Alb ratio, may be useful for predicting PC prognoses.
文摘AIM: To summarize the results of studies investigating neutrophil-to-lymphocyte ratio(NLR) and to identify the role of NLR in ocular diseases. METHODS: With the aim of identifying the studies related to NLR, a search was conducted on http://www.ncbi.nlm.nih.gov/pubmed by utilizing the key words "neutrophil lymphocyte ratio, ocular diseases, and eye diseases" up to February 2018. All of the original articles were assessed according to date of publications, countries, clinics and topics. Studies about ocular inflammatory diseases were evaluated according to their qualifications, review methods and results. RESULTS: A total of 4473 publications, including original research articles and reviews were screened. The number of publications was shown a regular logarithmic increase over the years. The majority of studies were performed by clinics in Turkey and many of these publications were performed by oncology and cardiology clinics. A total of 75 publications were identified to be about ocular diseases. CONCLUSION: Elevated NLR as a cheap, reproducible, and readily available marker could be used as a diagnostic and/or prognostic marker in ocular diseases.

文摘AIM: To evaluate the impact of postoperative infectious complications on hepatocellular carcinoma following curative hepatectomy.METHODS:We performed a retrospective analysis of200 hepatocellular carcinoma patients who underwent hepatectomy at our institution between September2003 and June 2011.The patients’demographics,clinicopathological characteristics and postoperative infectious complications were analyzed.The ClavienDindo classification was adopted to assess the severity of complications.The dynamic change in the neutrophilto-lymphocyte ratio,defined as the absolute neutrophil count divided by the absolute lymphocyte count,after surgery was also investigated.The observation endpoints for this study were recurrence-free survival and overall survival of the patients.Statistical analysis of the survival curves was performed using the KaplanMeier method and the log-rank test.The prognosticvalue of each variable for predicting prognosis was assessed via multivariate Cox proportional hazards regression analysis.The cutoff score for each variable was selected based on receiver operating characteristic curve analysis.All statistical tests were two-sided,and significance was set at P<0.05.RESULTS:The median age of the patients was 49years,and the majority of patients were male(86%)and had been infected with hepatitis B virus(86%).The 30-d postoperative infectious complication rate was34.0%(n=68).Kaplan-Meier survival analysis revealed that postoperative infection was significantly correlated with tumor recurrence(P<0.001).The postoperative intra-abdominal infection group exhibited a worse prognosis than the non-intra-abdominal infection group(P<0.001).A significantly increased incidence of postoperative intra-abdominal infection was observed in the patients with hepatic cirrhosis(P=0.028),concomitant splenectomy(P=0.007)or vascular invasion(P=0.026).The patients who had an elevated postoperative neutrophil-to-lymphocyte ratio change(>1.643)clearly exhibited poorer recurrence-free survival than those who did not(P=
文摘Background Currently, all the diagnostic indicators for endometriosis lack perfect sensitivity and specificity. According to the characteristic of endometriosis, we analyzed the new biomarker neutrophil-to-lymphocyte ratio （NLR） and the combination of NLR and serum CA-125 to investigate their diagnostic value for identifying stages III and IV endometdosis. Methods The values of serum CA-125 and routine blood tests were collected from 197 patients with endometriosis, 102 with benign tumors and 112 healthy individuals. We investigated the sensitivity and specificity of NLR and its combination with serum-CA-125 for diagnosing stages III and IV endometriosis by using receiver operating characteristic （ROC）. Results The mean values of NLR, the combination of serum CA-125 and NLR （combination） of the groups with stages III and IV endometriosis were significantly higher than the other two groups. Serum CA-125, NLR, and the combined biomarkers could significantly discriminate the stages Ill and IV endometriosis group from the other two groups （P〈0.05）. NLR shows a lower sensitivity of 57.9% and specificity of 65.2% with a cutoff value at 1.82. And the combination of biomarkers has the highest AUC of 0.949 with a sensitivity of 86.8% and specificity of 92.0% at the cutoff value of 44.40. In addition, for patients with negative CA-125, 55.36% and 53.57% of the patients were able to be diagnosed with endometriosis by using NLR alone and the combination of biomarkers. Conclusion For diagnosing stages III and IV endometriosis, the neutrophil-to-lymphocyte ratio is a better adjuvant to serum CA-125, and the neutrophil-to-lymphocyte ratio is valuable in diagnosing stages III and IV endometriosis for patients with negative serum CA-125.
文摘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.
文摘BACKGROUND Seeking potentially novel blood markers of liver fibrosis and steatosis is constantly of crucial importance.Despite a growing number of studies in this field of hepatology,a certain role of hematological indices in the course of liver disorders has not been fully elucidated,yet.AIM To evaluate a diagnostic accuracy of neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR)and mean platelet volume-to-platelet-ratio(MPR)in the course of alcoholic liver cirrhosis(ALC)and nonalcoholic fatty liver disease(NAFLD).METHODS One hundred forty-two patients with ALC,92 with NAFLD and 68 persons in control group were enrolled in the study.Hematological indices(NLR,PLR and MPR),indirect and direct markers of liver fibrosis(aspartate transaminase to alkaline transaminase ratio,aspartate transaminase to platelet ratio index,fibrosis-4,gamma-glutamyl transpeptidase to platelet ratio,procollagen Ⅰ carboxyterminal propeptide,procollagen Ⅲ aminoterminal propeptide,transforming growth factor-α,platelet-derived growth factor AB,laminin)were measured in each person.Model for end-stage liver disease(MELD)score in ALC group and NAFLD fibrosis score together with BARD score were calculated in NAFLD patients.Receiver operating characteristic(ROC)curves and area under the curve(AUC)values were applied to assess the sensitivity and specificity of examined markers and to evaluate proposed cut-offs of measured indices in the course of ALC and NAFLD.RESULTS MPR and NLR values in ALC patients were significantly higher in comparison to control group;PLR level was significantly lower.MPR and PLR correlated with assessed indirect and direct markers of liver fibrosis.MPR,NLR and PLR correlated with MELD score.NLR level in NAFLD patients was significantly higher in comparison to controls.MPR correlated with indirect markers of liver fibrosis and NAFLD fibrosis score.AUC values and proposed cut-offs for NLR,PLR and MPR in ALC patients were:0.821(>2.227),0.675(<70.445)and 0.929(>0.048),respectively.AUC values and proposed
文摘AIM To investigate whether the preoperative neutrophil-tolymphocyte ratio(NLR) could predict the prognosis of hepatocellular carcinoma(HCC) patients with portal/hepatic vein tumor thrombosis(PVTT/HVTT) after hepatectomy.METHODS The study population included 81 HCC patients who underwent hepatectomy and were diagnosed with PVTT/HVTT based on pathological examination. The demographics, laboratory analyses, and histopathology data were analyzed.RESULTS Overall survival(OS) and disease-free survival(DFS) were determined in the patients with a high(> 2.9) and low(≤ 2.9) NLR. The median OS and DFS duration in the high NLR group were significantly shorter than those in the low NLR group(OS: 6.2 mo vs 15.7 mo, respectively, P = 0.007; DFS: 2.2 mo vs 3.7 mo, respectively, P = 0.039). An NLR > 2.9 was identified as an independent predictor of a poor prognosis of OS(P = 0.034, HR = 1.866; 95%CI: 1.048-3.322) in uni-and multivariate analyses. Moreover, there was a significantly positive correlation between the NLR and the Child-Pugh score(r = 0.276, P = 0.015) and the maximum diameter of the tumor(r = 0.435, P < 0.001). Additionally, the NLR could enhance the prognostic predictive power of the CLIP score for DFS in these patients. CONCLUSION The preoperative NLR is a prognostic predictor after hepatectomy for HCC patients with PVTT/HVTT. NLR > 2.9 indicates poorer OS and DFS.
文摘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.
文摘AIM:To investigate the prevalence of diabetic retinopathy(DR)in residents of Shanghai and analyze the risk factors of DR.METHODS:This study involved 7233 patients with diabetes in 2016.The demographic data of the participants were collected using a questionnaire survey.Physical examination,laboratory tests,and ophthalmological examinations were conducted.Two professional ophthalmologists diagnosed and graded DR by fundus examination and then combined the results with fundus images.The unconditional multivariate Logistic regression analysis was used to determine the risk factors.RESULTS:In total,6978 patients with type 2 diabetes in Shanghai with a mean age of 68.33±8.40 y were recruited,including 2975 males(42.6%)and 4003 females(57.4%).Overall,1184 patients were diagnosed with DR,with a prevalence rate of 16.97%.Regression analysis showed that duration of diabetes(OR 1.061,95%CI 1.049-1.073),high systolic blood pressure(SBP;OR 1.071,95%CI 1.037-1.106),increased glycosylated hemoglobin level(OR 1.234,95%CI 1.162-1.311),high blood glucose level(OR 1.061,95%CI 1.023-1.099),increased neutrophil-to-lymphocyte ratio(NLR;OR 1.132,95%CI 1.053-1.217)and mean platelet volume(MPV;OR 1.077,95%CI 1.016-1.142)were risk factors of DR.Conversely,hematocrit(HCT;OR 0.971,95%CI 0.954-0.988)and mean corpuscular volume(MCV;OR 0.980,95%CI 0.965-0.994)were protective factors.CONCLUSION:The prevalence rate of DR in Shanghai is 16.97%.The duration of diabetes,high SBP,increased glycosylated hemoglobin,NLR,and MPV were determined as risk factors of DR.
文摘BACKGROUND Non-ST segment elevation myocardial infarction(NSTEMI)poses significant challenges in clinical management due to its diverse outcomes.Understanding the prognostic role of hematological parameters and derived ratios in NSTEMI patients could aid in risk stratification and improve patient care.AIM To evaluate the predictive value of hemogram-derived ratios for major adverse cardiovascular events(MACE)in NSTEMI patients,potentially improving clinical outcomes.METHODS A prospective,observational cohort study was conducted in 2021 at the Internal Medicine Clinic of the University Hospital in Tuzla,Bosnia and Herzegovina.The study included 170 patients with NSTEMI,who were divided into a group with MACE and a control group without MACE.Furthermore,the MACE group was subdivided into lethal and non-lethal groups for prognostic analysis.Alongside hematological parameters,an additional 13 hematological-derived ratios(HDRs)were monitored,and their prognostic role was investigated.RESULTS Hematological parameters did not significantly differ between non-ST segment elevation myocardial infarction(NSTEMI)patients with MACE and a control group at T1 and T2.However,significant disparities emerged in HDRs among NSTEMI patients with lethal and non-lethal outcomes post-MACE.Notably,neutrophil-to-lymphocyte ratio(NLR)and platelet-to-lymphocyte ratio(PLR)were elevated in lethal outcomes.Furthermore,C-reactive protein-to-lymphocyte ratio(CRP/Ly)at T1(>4.737)demonstrated predictive value[odds ratio(OR):3.690,P=0.024].Both NLR at T1(>4.076)and T2(>4.667)emerged as significant predictors,with NLR at T2 exhibiting the highest diagnostic performance,as indicated by an area under the curve of 0.811(95%CI:0.727-0.859)and OR of 4.915(95%CI:1.917-12.602,P=0.001),emphasizing its important role as a prognostic marker.CONCLUSION This study highlights the significant prognostic value of hemogram-derived indexes in predicting MACE among NSTEMI patients.During follow-up,NLR,PLR,and CRP/Ly offer important insights into the inflammatory proc
文摘BACKGROUND Identifying patients with peritoneal metastasis(PMs)of colorectal cancer(CRC)who will benefit from cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is crucial before surgery.Inflammatory and nutritional indicators play essential roles in cancer development and metastasis.AIM To investigate the association of preoperative inflammatory and nutritional markers with prognosis in patients with CRC-PM.METHODS We included 133 patients diagnosed with CRC-PM between July 2012 and July 2018.Patients’demographics,overall survival(OS),and preoperative inflammatory and nutritional markers were evaluated.The Kaplan-Meier method and log-rank test were used to estimate differences.RESULTS Of the 133 patients,94(70.6%)had normal hemoglobin(Hb)and 54(40.6%)had a high neutrophil-to-lymphocyte ratio(NLR).The median OS(mOS)was significantly lower for patients with high NLR(7.9 months)than for those with low NLR(25.4 months;P=0.002).Similarly,patients with normal Hb had a longer mOS(18.5 months)than those with low Hb(6.3 months;P<0.001).Multivariate analysis identified age,carbohydrate antigen 199 levels,NLR,Hb,and peritoneal cancer index as independent predictors of OS.Based on these findings,a nomogram was constructed,which demonstrated a good capacity for prediction,with a C-index of 0.715(95%confidence interval:0.684-0.740).Furthermore,the 1-and 2-year survival calibration plots showed good agreement between predicted and actual OS rates.The areas under the curve for the 1-and 2-year survival predictions of the nomogram were 0.6238 and 0.6234,respectively.CONCLUSION High NLR and low Hb were identified as independent predictive risk factors for poor prognosis in patients with CRC-PM.The established nomogram demonstrated high accuracy in predicting OS for patients with CRC-PM,indicating its potential as a valuable prognostic tool for this patient population.
文摘As the fifth most common gastrointestinal cancer worldwide,hepatocellular carcinoma(HCC)often presents at advanced stages of disease.For the subset of patients who present with tumor and liver-related features amenable to surgery,hepatic resection—in addition to transplantation—offers the best chance at curative-intent therapy.Resection can be associated,however,with risk of complications and perioperative death especially among individuals with concomitant portal hypertension,liver fibrosis,cirrhosis,and portal vein thrombosis(1-3).Post-resection liver failure is also a major concern and can be a devasting complication following hepatic resection(4,5).Overall survival following hepatic resection of HCC ranges from only 30–50%,and recurrence can be common depending on the stage of disease.In turn,there is considerable interest in identifying markers to help stratify patients relative to risk of recurrence and prognosis to define which groups of patients may benefit the most from hepatic resection of HCC(1-5).
