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

After Hepatocellular carcinoma, breast cancer, bladder cancer, lung cancer, Non-Hodgkin Lymphoma and brain tumors, colon cancer is the 7<sup>th</sup> most common cancer in Egypt, in both sexes, representing 3.47% and 3%, in both male and female cancers, respectively. Aim of the Work: The aim of this study was to evaluate the prognostic and predictive significance of pretreatment Neutrophil/lymphocytes ratio (NLR), in terms of disease-free survival (DFS) and recurrence, in high-risk stage II and stage III Colorectal cancer patients who underwent curative resection. Patients and Methods: We retrospectively evaluated 103 patients, who were submitted to upfront surgery as first therapeutic option in curative intent, between January 2017 and December 2018. Pretreatment Neutrophil/lymphocytes ratio (NLR), as well as demographics, clinical, histopathologic, and laboratory data were analyzed. Univariate and multivariate analyses were conducted to identify prognostic factors associated with disease free survival (DFS) and recurrence. Results: The cutoff point of Neutrophils/lymphocytes ratio (NLR) was calculated with Kaplan-Meier curves and log-rank test to 3. This study revealed that neutrophils/lymphocytes ratio (NLR) was significantly associated with disease free survival (p as no difference in efficacy between both chemotherapy regimens FOLFOX and XELOX in both high-risk stage II and stage III colon cancer regarding disease free survival & the toxicity profile associated with each regimen and its grades between patients. Conclusion: Our study suggests that preoperative Neutrophils/lymphocytes ratio (NLR) more than 3 may be an independent prognostic marker for TTR (time to recurrence) in high-risk stage II and stage III colon cancer patients.展开更多

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

The values of simple inflammatory markers including NLR and PLR in predicting the long-term outcomes of these patients were evaluated using Kaplan-Meier curves and Cox regression models.RESULTS The median follow-up duration was 46 mo(interquartile range, 22-73). The estimation of NLR and PLR was based on the time of diagnosis. In multivariate Cox regression analysis, high NLR (≥ 3.0) and high PLR(≥ 160) were independent risk factors predicting poor long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. However, high NLR and high PLR were not prognostic factors in patients with stage Ⅰ and Ⅱ CRC.CONCLUSION In this study, we identified that high NLR (≥ 3.0) and high PLR (≥ 160) are useful prognostic factors to predict long-term outcomes in patients with stage Ⅲ and Ⅳ CRC.展开更多

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

文摘T lymphocytes,the main participants of cellular immunity,can express a variety of surface molecules and form different lymphocyte subsets under the induction of different factors to play the functions of immune regulation and immune killing.Studies have shown that platelets play a crucial role in maintaining the stable differentiation of lymphocytes and the balance in immunomodulation.Therefore,it is necessary to study the effect of platelets on lymphocytes in vitro to better understand the role of platelets in the immune system and broaden the application of adoptive immunotherapy.Methods:Cell counting and microscopic observation were used to detect the effect of activated platelets on lymphocyte proliferation in vitro;Flow cytometry was used to detect whether changes in platelet activity affect the proportion of lymphocyte subpopulations in vitro,and to detect differences in the expression of granzyme B;lactate dehydrogenase assay(LDH)was used to determine the difference in lymphocyte killing activity caused by platelet activity in vitro.Results:This was the first to promote lymphocyte proliferation through the expression or release of certain molecules in vitro,demonstrating that platelet activation is one of the key factors.Secondly,activated platelets or inactivated platelets promoted lymphocyte subset differentiation by enhancing the proportion of CD3+CD8+T lymphocytes(CTL cells)but had a slight effect on the proportion of CD3+CD4+T(Th cells)and CD4+CD25+T lymphocytes(Treg cells).Then,it was found that either activated platelets or inactivated platelets down-regulated the proportion of natural killer(NK)T lymphocytes,while activated platelets significantly enhance the proportion of NK lymphocytes.Therefore,by further detecting the killing activity of PBMCs treated with platelets,it was found that activated platelets promoted the extensive anti-tumor activity of lymphocytes and significantly increased the expression of granzyme B.Conclusion:Our results suggest that activated platelets promote lymphocyte proliferation,optimize lymphocyte subpopulation ratio,and promote cytotoxic effect of lymphocytes in vitro,which may provide a new strategy for optimizing the adoptive immunotherapy culture system and improving its efficacy.

文摘BACKGROUND Circulating tumor cell(CTC)count and neutrophil-to-lymphocyte ratio(NLR)are both closely associated with the prognosis of hepatocellular carcinoma(HCC).AIM To investigate the prognostic value of combining these two indicators in HCC.METHODS Clinical data were collected from patients with advanced HCC who received im-mune therapy combined with targeted therapy at the Department of Oncology,the Affiliated Hospital of Southwest Medical University,Sichuan,China,from 2021 to 2023.The optimal cutoff values for CTC programmed death-ligand 1(PD-L1)(+)>1 or CTC PD-L1(+)≤1 and NLR>3.89 or NLR≤3.89 were evaluated using X-Tile software.Patients were categorized into three groups based on CTC PD-L1(+)counts and NLR:CTC-NLR(0),CTC-NLR(1),and CTC-NLR(2).The relationship between CTC-NLR and clinical variables as well as survival rates was assessed.RESULTS Patients with high CTC PD-L1(+)expression or NLR at baseline had shorter median progression-free survival(m-PFS)and median overall survival(mOS)than those with low levels of CTC PD-L1(+)or NLR(P<0.001).Mean-while,patients in the CTC-NLR(2)group showed a significant decrease in mPFS and mOS.Cox regression analysis revealed that alpha-fetoprotein(AFP),CTC PD-L1(+),and CTC-NLR were independent predictors of OS.The time-dependent receiver operating characteristic curve showed that the area under the curve of CTC-NLR at 12 months(0.821)and 18 months(0.821)was superior to that of AFP and CTC PD-L1(+).CONCLUSION HCC patients with high CTC PD-L1(+)or NLR expression tend to exhibit poor prognosis,and a high baseline CTC-NLR score may indicate low survival.CTC-NLR may serve as an effective prognostic indicator for patients with advanced HCC receiving immunotherapy combined with targeted therapy.

文摘BACKGROUND The prognostic impact of preoperative gamma-glutamyl transpeptidase to platelet ratio(GPR)levels in patients with solitary hepatitis B virus(HBV)-related hepatocellular carcinoma(HCC)following radical resection has not been established.AIM To examine the clinical utility of GPR for prognosis prediction in solitary HBVrelated HCC patients.METHODS A total of 1167 solitary HBV-related HCC patients were retrospectively analyzed.GPR levels were compared with 908 non-HCC individuals.Overall survival(OS)and recurrence-free survival(RFS)were evaluated,and cox proportional hazard model analyses were performed to identify independent risk factors.Differences in characteristics were adjusted by propensity score matching(PSM).Subgroup and stratified survival analyses for HCC risks were performed,and a linear trend of the hazard ratio(HR)according to GPR levels was constructed.RESULTS GPR levels of patients with solitary HBV-related HCC were higher than those with hepatic hemangiomas,chronic hepatitis B and healthy control(adjusted P<0.05).Variable bias was diminished after the PSM balance test.The low GPR group had improved OS(P<0.001)and RFS(P<0.001)in the PSM analysis and when combined with other variables.Multivariate cox analyses suggested that low GPR levels were associated with a better OS(HR=0.5,95%CI:0.36-0.7,P<0.001)and RFS(HR=0.57,95%CI:0.44-0.73,P<0.001).This same trend was confirmed in subgroup analyses.Prognostic nomograms were constructed and the calibration curves showed that GPR had good survival prediction.Moreover,stratified survival analyses found that GPR>0.6 was associated with a worse OS and higher recurrence rate(P for trend<0.001).CONCLUSION Preoperative GPR can serve as a noninvasive indicator to predict the prognosis of patients with solitary HBVrelated HCC.
文摘BACKGROUND For compensated advanced chronic liver disease(cACLD)patients,the first decompensation represents a dramatically worsening prognostic event.Based on the first decompensation event(DE),the transition to decompensated advanced chronic liver disease(dACLD)can occur through two modalities referred to as acute decompensation(AD)and non-AD(NAD),respectively.Clinically Significant Portal Hypertension(CSPH)is considered the strongest predictor of decompensation in these patients.However,due to its invasiveness and costs,CSPH is almost never evaluated in clinical practice.Therefore,recognizing noninvasively predicting tools still have more appeal across healthcare systems.The red cell distribution width to platelet ratio(RPR)has been reported to be an indicator of hepatic fibrosis in Metabolic Dysfunction-Associated Steatotic Liver Disease(MASLD).However,its predictive role for the decompensation has never been explored.AIM In this observational study,we investigated the clinical usage of RPR in predicting DEs in MASLD-related cACLD patients.METHODS Fourty controls and 150 MASLD-cACLD patients were consecutively enrolled and followed up(FUP)semiannually for 3 years.At baseline,biochemical,clinical,and Liver Stiffness Measurement(LSM),Child-Pugh(CP),Model for End-Stage Liver Disease(MELD),aspartate aminotransferase/platelet count ratio index(APRI),Fibrosis-4(FIB-4),Albumin-Bilirubin(ALBI),ALBI-FIB-4,and RPR were collected.During FUP,DEs(timing and modaities)were recorded.CSPH was assessed at the baseline and on DE occurrence according to the available Clinical Practice Guidelines.RESULTS Of 150 MASLD-related cACLD patients,43(28.6%)progressed to dACLD at a median time of 28.9 months(29 NAD and 14 AD).Baseline RPR values were significantly higher in cACLD in comparison to controls,as well as MELD,CP,APRI,FIB-4,ALBI,ALBI-FIB-4,and LSM in dACLD-progressing compared to cACLD individuals[all P<0.0001,except for FIB-4(P:0.007)and ALBI(P:0.011)].Receiving operator curve analysis revealed RPR>0.472 and>0.894 as the best cut-offs in the prediction respectively of 3-year first DE,as well as its superiority compared to the other non-invasive tools examined.RPR(P:0.02)and the presence of baseline-CSPH(P:0.04)were significantly and independently associated with the DE.Patients presenting baseline-CSPH and RPR>0.472 showed higher risk of decompensation(P:0.0023).CONCLUSION Altogether these findings suggest the RPR as a valid and potentially applicable non-invasive tool in the prediction of timing and modalities of decompensation in MASLD-related cACLD patients.
文摘Introduction: Hypertensive disorder in pregnancy affects 4 to 6 percent of all pregnancies and carries risks for the both baby and the mother. Only a few groups of women who are at high-risk pregnancies are received prophylaxis Aspirin, more than 15 percent of women develop pre-eclampsia with a single minor risk factor. Methods: This descriptive cross-sectional study was conducted to compare the 1<sup>st</sup> trimester NLR value of normotensive, pregnancy induced hypertensive and pre-eclamptic pregnant women. The study was conducted with a sample of 416, antenatal patients who were admitted to ward 25, at Colombo North Teaching Hospital Ragama. Data was collected as separated three groups. NLR value was calculated separately and ANOVA test was used to analyze the 3 categorical data. Post HOC test was done to assess the multiple comparison. Results: The prevalence rates of pregnancy induced hypertension and pre-eclampsia among the pregnant women were 8.6% and 5.7%. The mean NLR values of normotensive group was 2.708, pregnancy induced hypertensive group was 2.650 and pre eclamptic group was 3.789. There was a significant difference in NLR value between pre eclamptic group and other two groups with P value of Conclusion: The 1<sup>st</sup> trimester NLR value of pre eclamptic patients significantly increased compared to normotensive women.
文摘BACKGROUND The lymphocyte to monocyte ratio(LMR)is considered a marker of systemic inflammation in cardiovascular disease and acts as predictor of mortality in coronary artery disease.AIM To investigate the predictive role of LMR in diabetic coronary artery disease patients.METHODS This cross-sectional study was conducted at tertiary care super-specialty hospital at New Delhi,India.A total of 200 angiography-proven coronary artery disease(CAD)patients were enrolled and grouped into two categories:Group I[CAD patients with type 2 diabetes mellitus(T2DM)and glycated hemoglobin(HbA1c)levels≥6.5%],and Group II(CAD patients without T2DM and HbA1c levels<6.5%).Serum lipoproteins,HbA1c,and complete blood count of enrolled patients were analyzed using fully automatic analyzers.RESULTS The logistic regression analysis showed an odds ratio of 1.48(95%CI:1.28-1.72,P<0.05)for diabetic coronary artery disease patients(Group I)in unadjusted model.After adjusting for age,gender,diet,smoking,and hypertension history,the odds ratio increased to 1.49(95%CI:1.29-1.74,P<0.01)in close association with LMR.Further adjustment for high cholesterol and triglycerides yielded the same odds ratio of 1.49(95%CI:1.27-1.75,P<0.01).Receiver operating characteristic curve analysis revealed 74%sensitivity,64%specificity,and 0.74 area under the curve(95%CI:0.67-0.80,P<0.001),suggesting moderate predictive accuracy for diabetic CAD patients.CONCLUSION LMR showed positive association with diabetic coronary artery disease,with moderate predictive accuracy.These findings have implications for improving CAD management in diabetics,necessitating further research and targeted interventions.
文摘Objective: To investigate the value of peripheral blood helper T cell 17 cell level and monocyte/lymphocyte ratio to predict the prognosis of colorectal cancer patients. Methods: 74 colorectal cancer patients who attended Hospital 960 from January 2021 to January 2022 were retrospectively analyzed. Clinical data of the patients were collected, including gender, age, and histologic type. Immunohistochemical indexes such as Th17 cell level and monocyte/ lymphocyte ratio in the peripheral blood of patients were also collected. The prognosis of patients after treatment, as well as peripheral blood Th17 and MLR levels, were observed and analyzed. Results: After follow-up after treatment, in the final 74 patients, the prognosis was good in 32 patients, accounting for 43.24%, and the prognosis was bad in 42 patients, accounting for 56.76%. There were no significant differences between the average age and tumor diameters of the good prognosis and poor prognosis groups (P > 0.05). However, the TNM staging, intervention taken, differentiation degree, presence of distant metastasis, presence of lymph node metastasis, Th17 level, and MLR level are significantly different between the two groups (P < 0.05). Conclusion: Peripheral blood Th17 and MLR have predictive value for the prognosis of colorectal cancer patients, and high levels of peripheral blood Th17 and MLR imply poor prognosis. The detection of peripheral blood Th17 and MLR levels is simple and convenient and can be used as indicators to provide a reference for the prognostic assessment of colorectal cancer patients.
文摘Background: In developed countries, colon cancer is the second most prevalent cancer, only exceeded by prostate cancer in men and breast cancer in women. After Hepatocellular carcinoma, breast cancer, bladder cancer, lung cancer, Non-Hodgkin Lymphoma and brain tumors, colon cancer is the 7<sup>th</sup> most common cancer in Egypt, in both sexes, representing 3.47% and 3%, in both male and female cancers, respectively. Aim of the Work: The aim of this study was to evaluate the prognostic and predictive significance of pretreatment Neutrophil/lymphocytes ratio (NLR), in terms of disease-free survival (DFS) and recurrence, in high-risk stage II and stage III Colorectal cancer patients who underwent curative resection. Patients and Methods: We retrospectively evaluated 103 patients, who were submitted to upfront surgery as first therapeutic option in curative intent, between January 2017 and December 2018. Pretreatment Neutrophil/lymphocytes ratio (NLR), as well as demographics, clinical, histopathologic, and laboratory data were analyzed. Univariate and multivariate analyses were conducted to identify prognostic factors associated with disease free survival (DFS) and recurrence. Results: The cutoff point of Neutrophils/lymphocytes ratio (NLR) was calculated with Kaplan-Meier curves and log-rank test to 3. This study revealed that neutrophils/lymphocytes ratio (NLR) was significantly associated with disease free survival (p as no difference in efficacy between both chemotherapy regimens FOLFOX and XELOX in both high-risk stage II and stage III colon cancer regarding disease free survival & the toxicity profile associated with each regimen and its grades between patients. Conclusion: Our study suggests that preoperative Neutrophils/lymphocytes ratio (NLR) more than 3 may be an independent prognostic marker for TTR (time to recurrence) in high-risk stage II and stage III colon cancer patients.

文摘BACKGROUND Preoperative pulmonary function plays an important role in selecting surgical candidates and assessing postoperative complications.Reduced pulmonary function is associated with poor survival in several cancers,but the prognostic value of preoperative pulmonary function in esophageal squamous cell carcinoma(ESCC)is unclear.Nutritional and systemic inflammation parameters are vital to cancer survival,and the combination of these parameters improves the prognostic value.The hemoglobin,albumin,lymphocytes and platelets(HALP)score is a novel prognostic indicator to reflect the nutritional and inflammation status,but the clinical effects of the HALP score combined with maximal voluntary ventilation(MVV),an important parameter of pulmonary function,have not been well studied in ESCC.AIM To investigate the prognostic value of MVV and HALP score for assessing postoperative survival of ESCC patients.METHODS Data form 834 ESCC patients who underwent radical esophagectomy with R0 resection were collected and retrospectively analyzed.Preoperative MVV and HALP data were retrieved from medical archives.The HALP score was calculated by the formula:Hemoglobin(g/L)×albumin(g/L)×lymphocytes(/L)/platelets(/L).The optimal cut-off values of MVV and HALP score were calculated by the receiver operating characteristic curve analysis.The Kaplan-Meier method with log-rank test was used to draw the survival curves for the variables tested.Multivariate Cox proportional hazard regression models were used to analyze the independent prognostic factors for overall survival.RESULTS MVV was significantly associated with gender(P<0.001),age at diagnosis(P<0.001),smoking history(P<0.001),drinking history(P<0.001),tumor length(P=0.013),tumor location(P=0.037)and treatment type(P=0.001).The HALP score was notably associated with gender(P<0.001),age at diagnosis(P=0.035),tumor length(P<0.001)and invasion depth(P=0.001).Univariate Cox regression analysis showed that low MVV and low HALP score were associated with worse overall survival(all P<0.001).Multivariate analysis showed that low MVV and the HALP score were both independent risk factors for overall survival(all P<0.001).The combination of MVV and HALP score improved the prediction performance for overall survival than tumor-node-metastasis.Also,low combination of MVV and HALP score was an independent risk factor for poor overall survival(P<0.001).CONCLUSION MVV,HALP score and their combination are simple and promising clinical markers to predict overall survival of ESCC patients.
文摘Background: Acute myocardial infarction is a leading cause of death worldwide nowadays and treatment of choice is primary percutaneous coronary intervention (PCI). No reflow is a complication that increases mortality and morbidity post intervention and one of its predictors is platelet lymphocyte ratio. Aim of Study: To assess relation between admission platelet to lymphocyte ratio (PLR) and angiographic reflow after primary PCI in acute ST elevation myocardial infarction (STEMI). Patients and Methods: This is a prospective study that was conducted from May 2017 to May 2018 at Cardiology Department, Menoufia University Hospital. Sixty patients presented with ST-elevation myocardial infarction who were eligible for primary PCI were enrolled in the study. According to TIMI flow post intervention, patients were arranged into 2 groups: Group 1 (Normal Reflow) included thirty patients with post intervention TIMI flow III and Group 2 (NO Reflow) included thirty patients with post intervention TIMI flow (0, I, II). Comparison between both groups was done regarding platelet lymphocyte ratio (PLR). Result: PLR was significantly higher in patients with coronary no reflow than in patients with normal reflow with a P-value of , timing interval between onset of chest pain to time of intervention and thrombus grading was significantly higher in patients with no reflow than in patients with normal reflow. Conclusion: Pre-intervention PLR is an independent predictor of slow flow/no reflow following PPCI in patient with acute STEMI.
文摘BACKGROUND The hemoglobin,albumin,lymphocyte,and platelet(HALP)score,derived from a composite evaluation of markers reflecting the tumor-inflammation relationship and nutritional status,has been substantiated as a noteworthy prognostic determinant for diverse malignancies.AIM To investigate how the HALP score relates to prognosis in patients with metastatic gastric cancer.METHODS The cutoff values for the HALP score,neutrophil/lymphocyte ratio,and platelet/lymphocyte ratio were determined using receiver operating characteristic analysis.Low HALP scores were defined as those less than 24.79 and high HALP scores as those greater than 24.79.RESULTS The study cohort comprised 147 patients and 110 of them(74.8%)were male.The patients'median age was 63(22-89)years.The median overall survival was significantly superior in the patients with high HALP scores than in those with low HALP scores(10.4 mo vs 7.5 mo,respectively;P<0.001)CONCLUSION The HALP score was found to be a prognostic factor in patients with metastatic gastric cancer.
文摘AIM To evaluate the prognostic value of the neutrophil-tolymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) in patients with colorectal cancer(CRC).METHODS Between April 1996 and December 2010, medical records from a total of 1868 patients with CRC were retrospectively reviewed. The values of simple inflammatory markers including NLR and PLR in predicting the long-term outcomes of these patients were evaluated using Kaplan-Meier curves and Cox regression models.RESULTS The median follow-up duration was 46 mo(interquartile range, 22-73). The estimation of NLR and PLR was based on the time of diagnosis. In multivariate Cox regression analysis, high NLR (≥ 3.0) and high PLR(≥ 160) were independent risk factors predicting poor long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. However, high NLR and high PLR were not prognostic factors in patients with stage Ⅰ and Ⅱ CRC.CONCLUSION In this study, we identified that high NLR (≥ 3.0) and high PLR (≥ 160) are useful prognostic factors to predict long-term outcomes in patients with stage Ⅲ and Ⅳ CRC.

文摘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 significantlypositively correlated with CA125 serum level,tumornode-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.
文摘In the present study,we aimed at exploring the applied value of preoperative neutrophil lymphocyte ratio(NLR)and platelet lymphocyte ratio(PLR)in the prediction of lymph node metastasis(LNM)and prognosis in patients with early gastric cancer(EGC).We retrospectively analyzed a total of 248 consecutive patients who underwent curative gastrectomy to be identified T1 stage gastric adenocarcinoma between January 1,2010 and May 1,2016 in a single institution.According to median preoperative NLR and PLR value,we divided the patients into four groups:high NLR≥1.73 and low NLR〈1.73,high PLR≥117.78 and low PLR〈117.78.Furthermore,to evaluate the relationship between preoperative NLR and PLR values,we categorized patients according to cutoff preoperative NLR-PLR score of 2[high NLR(≥1.73)and high PLR(≥117.78)],1[either high NLR or high PLR],and 0[neither high NLR nor high PLR].Statistical analyses were conducted using SPSS 20.0 software.The results showed that the preoperative NLR or PLR values,lower or higher,could not predict the LNM in patients with EGC(both P=0.5440.05).The invasive depth of tumor was significantly correlated with LNM of EGC(P〈0.001).Kaplan-Meier plots illustrated that preoperative NLR and PLR values were not associated with overall survival(OS)in patients with EGC.It was concluded that the preoperative NLR and PLR may be the predictors for LNM and prognosis in patients with advanced gastric cancer;nevertheless,they cannot predict LNM and prognosis in patients with EGC.
文摘Background:The preoperative neutrophil-to-lymphocyte ratio(NLR) and the platelet-to-lymphocyte ratio(PLR) are associated with poor prognosis of gastric cancer.We aimed to determine whether the combination of NLR and PLR(NLR-PLR) could better predict survival of patients after curative resection for stage Ⅰ-Ⅱ gastric cancer.Methods:We collected data from the medical records of patients with stage Ⅰ-Ⅱ gastric cancer undergoing curative resection between December 2000 and November 2012 at the Sun Yat-sen Cancer Center.The preoperative NLRPLR was calculated as follows:patients with both elevated NLR(≥2.1) and PLR(≥ 120) were given a score of 2,and patients with only one or neither were given a score of 1 or 0,respectively.Results:Kaplan-Meier analysis and log-rank tests revealed significant differences in overall survival(OS) among patients with NLR-PLR scores of 0,1 and 2(P < 0.001).Multivariate analysis showed that OS was independently associated with the NLR-PLR score[hazard ratio(HR) = 1.51,95%confidence interval(CI) 1.02-2.24,P = 0.039]and TNM stage(HR = 1.36,95%CI 1.01-1.83,P= 0.041).However,other systemic inflammation-based prognostic scores,including the modified Glasgow prognostic score,the prognostic nutritional index,and the combination of platelet count and NLR,were not.In TNM stage-stratified analysis,the prognostic significance of NLR-PLR was maintained in patients with stage Ⅰ(P < 0.001) and stage Ⅱ cancers(P= 0.022).In addition,the area under the receiver operating characteristic curve for the NLR-PLR score was higher than those of other systemic inflammation-based prognostic scores(P = 0.001).Conclusion:The preoperative NLR-PLR score is a useful predictor of postoperative survival in the patients with stage l-ll gastric cancer and may help identify high-risk patients for rational therapy and timely follow-up.
文摘AIM： To assess the levels of the neutrophil to lymphocyte ratio（N/L） and the platelet to lymphocyte ratio（P/L） in patients with idiopathic acute anterior uveitis（AAU） and to compare with healthy controls.METHODS： Thirty-six male patients with idiopathic AAU and 36 male healthy subjects were enrolled in this retrospective study.Complete ophthalmological examination and complete blood count measurements results of all subjects were evaluated.RESULTS： There was a significant difference in N/L and P/L between idiopathic AAU and control groups（P=0.006,P=0.022）.Also,correlation analysis revealed a significant correlation between C-reactive protein（CRP） and N/L（P= 0.002;r=0.461）.CONCLUSION： Our study for the first time provides evidence of N/L and P/L may be useful biomarkers in patients with idiopathic AAU.N/L is correlated with CRP,so it can be a useful biomarker to predict the prognosis in idiopathic AAU.
文摘AIM To perform a systematic review and meta-analysis on platelet-to-lymphocyte ratio(PLR) as a risk factor for post-transplant hepatocellular cancer(HCC) recurrence. METHODS A systematic literature search was performed using PubM ed. Participants of any age and sex, who underwent liver transplantation for HCC were considered following these criteria:(1) studies comparing pre-transplant low vs high PLR values;(2) studies reporting post-transplant recurrence rates; and(3) if more than one study was reported by the same institute, only the most recent was included. The primary outcome measure was set for HCC recurrence after transplantation. RESULTS A total of 5 articles, published between 2014 and 2017, fulfilled the selection criteria. As for the quality of the reported studies, all the investigated articles presented an overall high quality. A total of 899 cases were investigated: 718 cases(80.0%) were males. Three studies coming from European countries and one from Japan presented HCV as the main cause of cirrhosis. On the opposite, one Chinese study presented a greater incidence of HBV-related cirrhotic cases. In all the studies apart one, the PLR cut-off value of 150 was reported. At meta-analysis, high PLR value was associated with a significant increase in recurrence after transplantation(OR = 3.33; 95%CI: 1.78-6.25; P < 0.001). A moderate heterogeneity was observed among the identified studies according to the Higgins I^2 statistic value.CONCLUSION Pre-transplant high PLR values are connected with an increased risk of post-operative recurrence of hepatocellular cancer. More studies are needed for better clarify the biological mechanisms of this results.
文摘BACKGROUND Some studies investigated the prognostic role of several blood biomarkers,including the neutrophil/lymphocyte ratio(NLR),platelet/lymphocyte ratio(PLR),lymphocyte/monocyte ratio(LMR)and Glasgow prognostic score(GPS),in osteosarcoma,but their results were inconsistent with each other.AIM To identify the prognostic value of NLR,PLR,LMR and GPS in osteosarcoma patients through reviewing relevant studies.METHODS The PubMed,EMBASE,Web of Science and CNKI databases were searched up to October 2,2021.The primary and second outcomes were overall survival(OS)and disease-free survival(DFS),respectively.The hazard ratios(HRs)with 95%confidence intervals(CIs)were combined to assess the association between these indicators and prognosis of osteosarcoma patients.RESULTS A total of 13 studies involving 2087 patients were eventually included.The pooled results demonstrated that higher NLR and GPS were significantly associated with poorer OS(HR=1.88,95%CI:1.38-2.55,P<0.001;HR=2.19,95%CI:1.64-2.94,P<0.001)and DFS(HR=1.67,95%CI:1.37-2.04,P<0.001;HR=2.50,95%CI:1.39-4.48,P<0.001).However,no significant relationship of PLR and LMR and OS(P=0.085;P=0.338)and DFS(P=0.396;P=0.124)was observed.CONCLUSION Higher NLR and GPS were related with worse prognosis and might serve as novel prognostic indicators for osteosarcoma patients.
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 In malignant tumors,inflammation plays a vital role in the development,invasion,and metastasis of cancer cells.Diffuse large B-cell lymphoma(DLBCL),the most common malignant proliferative disease of the lymphatic system,is commonly associated with inflammation.The international prognostic index(IPI),which includes age,lactate dehydrogenase(LDH),number of extranodal lesions,Ann Arbor score,and Eastern Cooperative Oncology Group(ECOG)score,can evaluate the prognosis of DLBCL.However,its use in accurately identifying highrisk patients and guiding treatment is poor.Therefore,it is important to find novel immune markers in predicting the prognosis of DLBCL patients.AIM To determine the association between the systemic immune inflammation index(SII),ratio of lymphocytes to monocytes(LMR),ratio of LMR to LDH(LMR/LDH),and prognosis of patients with DLBCL.METHODS A total of 68 patients diagnosed with DLBCL,treated in our hospital between January 2016 and January 2020,were included.χ2 test,Pearson’s R correlation,Kaplan Meier curves,and Cox proportional risk regression analysis were used.The differences in the SII,LMR,and LMR/LDH among patients with different clinicopathological features were analyzed.The differences in progression-free survival time among patients with different SII,LMR,and LMR/LDH expressions and influencing factors affecting the prognosis of DLBCL patients,were also analyzed.RESULTS The LMR and LMR/LDH in patients with Ann Arbor stage III–IV,ECOG score≥2,and SII,IPI score 2–5 were significantly higher than those of patients with Ann Arbor stage I-II and ECOG score<2(P<0.05).Patients with high SII,LMR,and LMR/LDH had progression-free survival times of 34 mo(95%CI:32.52–38.50),35 mo(95%CI:33.42–36.58)and 35 mo(95%CI:33.49–36.51),respectively,which were significantly lower than those with low SII,LMR,and LMR/LDH(P<0.05);the SII,LMR,and LMR/LDH were positively correlated(P<0.05).Cox proportional risk regression analysis showed that the SII,LMR,and LMR/LDH were influencing factors for the prognosis of DLBCL patients(hazard ratio=1.143,1.665,and 1.704,respectively;P<0.05).CONCLUSION The SII,LMR,and LMR/LDH are related to the clinicopathological features of DLCBL,and they also influence the prognosis of patients with the disease.
