Application of neutrophil-lymphocyte ratio and red blood cell distribution width in diabetes mellitus complicated with heart failure

BACKGROUND Accumulating clinical evidence has shown that diabetes mellitus(DM)is a serious risk factor for cardiovascular disorders and an important factor for adverse cardiovascular events.AIM To explore the value of the combined determination of the neutrophil-lymphocyte ratio(NLR)and red blood cell distribution width(RDW)in the early diagnosis and prognosis evaluation of DM complicated with heart failure(HF).METHODS We retrospectively analyzed clinical data on 65 patients with type 2 DM(T2DM)complicated with HF(research group,Res)and 60 concurrent patients with uncomplicated T2DM(control group,Con)diagnosed at Zhejiang Provincial People’s Hospital between January 2019 and December 2021.The NLR and RDW values were determined and comparatively analyzed,and their levels in T2DM+HF patients with different cardiac function grades were recorded.The receiver operating characteristic(ROC)curves were plotted to determine the NLR and RDW values(alone and in combination)for the early diagnosis of HF.The correlation between NLR and RDW with the presence or absence of cardiac events was also investigated.RESULTS Higher NLR and RDW levels were identified in the Res vs the Con groups(P<0.05).The NLR and RDW increased gradually and synchronously with the deterioration of cardiac function in the Res group,with marked differences in their levels among patients with grade II,III,and IV HF(P<0.05).ROC curve analysis revealed that NLR combined with RDW detection had an area under the curve of 0.915,a sensitivity of 76.9%,and a specificity of 100%for the early diagnosis of HF.Furthermore,HF patients with cardiac events showed higher NLR and RDW values compared with HF patients without cardiac events.CONCLUSION NLR and RDW were useful laboratory indicators for the early diagnosis of DM complicated with HF,and their joint detection was beneficial for improving diagnostic efficiency.Additionally,NLR and RDW values were directly proportional to patient outcomes.

Baseline neutrophil-lymphocyte ratio and platelet-lymphocyte ratio appear predictive of immune treatment related toxicity in hepatocellular carcinoma

BACKGROUND A well-recognized class effect of immune checkpoint inhibitors(ICI)is immune-related adverse events(IrAEs)ranging from low grade toxicities to life-threatening end organ damage requiring permanent discontinuation of ICI.Deaths are reported in<5%of patients treated with ICI.There are,however,no reliable markers to predict the onset and severity of IrAEs.We tested the association between neutrophil-lymphocyte ratio(NLR)and platelet-lymphocyte ratio(PLR)at baseline with development of clinically significant IrAEs(grade≥2)in hepatocellular carcinoma(HCC)patients treated with ICI.AIM To test the association between NLR and PLR at baseline with development of clinically significant IrAEs(grade≥2)in HCC patients treated with ICI.METHODS Data was extracted from an international database from a consortium of 11 tertiary-care referral centers.NLR=absolute neutrophil count/absolute lymphocyte count(ALC)and PLR=platelet count/ALC.Cutoff of 5 was used for NLR and 300 for PLR based on literature.We also tested the association between RESULTS Data was collected from 361 patients treated between 2016-2020 across the United States(67%),Asia(14%)and Europe(19%).Most patients received Nivolumab(n=255,71%).One hundred sixty-seven(46%)patients developed at least one IrAE,highest grade 1 in 80(48%),grade≥2 in 87(52%)patients.In a univariable regression model PLR>300 was significantly associated with a lower incidence of grade≥2 IrAEs(OR=0.40;P=0.044).Similarly,a trend was observed between NLR>5 and lower incidence of grade≥2 IrAEs(OR=0.58;P=0.097).Multivariate analyses confirmed PLR>300 as an independent predictive marker of grade≥2 IrAEs(OR=0.26;P=0.011),in addition to treatment with programmed cell death ligand 1(PD-1)/cytotoxic T lymphocyte-associated protein-4(OR=2.57;P=0.037)and PD-1/tyrosine kinase inhibitor(OR=3.39;P=0.01)combinations.Antibiotic use was not associated with IrAE incidence(OR=1.02;P=0.954).Patients treated with steroids had a>2-fold higher incidence of grade≥2 IrAEs(OR=2.74;P<0.001),although 74%were prescribed steroids for the treatment of IrAEs.CONCLUSION Given that high baseline NLR and PLR are associated with a decreased incidence of IrAEs,lower baseline NLR and PLR may be predictive biomarkers for the appearance of IrAEs in HCC treated with ICI.This finding is in keeping with several studies in solid tumors that have shown that baseline NLR and PLR appear predictive of IrAEs.

Neutrophil-lymphocyte ratio predicts the prognosis of patients with hepatocellular carcinoma after liver transplantation

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.

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

AIM: To determine the prognostic significance of preoperative serum neutrophil-lymphocyte ratio(NLR) in esophageal squamous cell carcinoma(ESCC).METHODS: Data from 371 eligible patients with ESCC who had undergone surgery with curative intent at our institution between October 2000 and May 2007 were retrospectively recruited for analysis. The cutoff value of NLR was 3.0 as determined by the receiver operating characteristic curve, which discriminated between survival and death; the area under the curve was 0.709, and the sensitivity and specificity were 66.1% and 69.1%, respectively, at the cutoff point. The correlation between the NLR and clinicopathological characteristics was analyzed using a χ2 test. The prognostic influence of the NLR and other clinicopathological factors on cancer-specific survival(CSS) and recurrence-free survival(RFS) was studied using the Kaplan-Meier method. To evaluate the independent prognostic value of NLR, multivariate Cox regression models were applied.RESULTS:The median age of the patients was 57.0years,and 276/371(74.4%)patients were male.The NLR was≤3.0 in 80.1%(297/371)of the patients,and the remaining 19.9%(74/371)had an 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.

Neutrophil-lymphocyte ratio:A prognostic tool in patients with inhospital cardiac arrest

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.

Comparison of prognostic factors in different age groups and prognostic significance of neutrophil-lymphocyte ratio in patients with gastric cancer

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.

Value of neutrophil-lymphocyte ratio in evaluating response to percutaneous catheter drainage in patients with acute pancreatitis

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.

Neutrophil-Lymphocyte Ratio as a Prognostic Factor in Incurable Stage IV Colorectal Cancer

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.

Neutrophil-lymphocyte ratio in the management and prediction of outcomes in renal cell carcinoma

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.

Neutrophil-lymphocyte ratio in pregnancy-associated maternal complications: A review

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.

Significance of preoperative peripheral blood neutrophil-lymphocyte ratio in predicting postoperative survival in patients with multiple myeloma bone disease

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.

Short-term impacts of air pollution on the platelet-lymphocyte ratio and neutrophil-lymphocyte ratio among urban adults in China

The short-term impacts of urban air pollution on the platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) remain obscure.In this study,we included 3487 urban adults from the Wuhan-Zhuhai cohort.Individual inhalation exposure to air pollutants was estimated by combining participants’daily breath volume and ambient concentrations of six air pollutants (includingfine particulate matter (PM_(2.5)),inhalable particulate matter(PM_(10)),nitrogen dioxide (NO_(2)),sulfur dioxide (SO_(2)),carbon monoxide (CO) and ozone (O_(3))).The cumulative impacts were assessed by applying lag structures of up to 7 days before the survey date.Associations of air pollutants with PLR and NLR were assessed using a linear mixed model and Bayesian kernel machine regression (BKMR) model.We found that PLR was negatively related to PM_(2.5)(lag02-lag06),PM_(10)(lag02-lag07),NO_(2)(lag02-lag07),and SO_(2)(lag03-lag05) and NLR was negatively related to PM_(10)(lag05 and lag07).In the BKMR model,a negative joint association between the six-air-pollutant mixture and PLR and NLR was observed,whereas PM_(10)and NO_(2)appeared to be more important than the other pollutants in the mixture.The negative impact of air pollutants was stronger in males,participants with lower body mass index (<24 kg/m^(2)),those cooking meals at home,drinkers,and nonexercisers.In conclusion,short-term exposure to air pollutants is significantly related to PLR and NLR in peripheral blood.PLR and NLR may provide new insight into the molecular mechanism underlying the adverse health impact of air pollutants.

The predictive role of the neutrophil-lymphocyte ratio in the prognosis of adult patients with stroke

Our study aimed to determine the effect of the neutrophil-lymphocyte ratio on the prognosis of adult patients with acute stroke.We searched the Web of Science,PubMed,Embase,Cochrane Library,and China National Knowledge Infrastructure databases and selected all of the potentially eligible studies.From the included studies,we extracted characteristics such as the stroke type and acquisition time until routine blood collection and the odds ratios across studies.The 95%confidence intervals and odds ratios were pooled to calculate the effect size for the neutrophil-lymphocyte ratio in acute stroke patients.We defined poor function outcomes according to the modified Rankin Scale≥3 or Glasgow Outcome Scale<3.Thirteen studies with 4443 patients were included in our analysis,including 7 ischemic and 6 hemorrhagic stroke studies.The pooled odds ratios for poor functional outcome at 3 months with a higher neutrophil-lymphocyte ratio in acute ischemic and hemorrhagic patients were 1.689(95%CI=1.184-2.409,p<0.001)and 1.125(95%CI=1.022-1.239,p<0.001),respectively,and the overall pooled odds ratio for poor functional outcome following stroke was 1.257(95%CI=1.146-1.379,p<0.001).At the same time,the overall combined odds ratio for death at 3 months was 1.632(95%CI=1.155-2.306,p<0.001).The neutrophil-lymphocyte ratio,an easily calculated marker,plays a predictive role in the short-term outcomes of adult patients(mean age≥50 years)following acute ischemic and hemorrhagic stroke.

Novel immunological and nutritional-based prognostic index for gastric cancer

AIM: To assess the prognostic significance of immunological and nutritional-based indices, including the prognostic nutritional index(PNI), neutrophillymphocyte ratio(NLR), and platelet-lymphocyte ratio in gastric cancer.METHODS: We retrospectively reviewed 632 gastric cancer patients who underwent gastrectomy between1998 and 2008. Areas under the receiver operating characteristic curve were calculated to compare the predictive ability of the indices, together with estimating the sensitivity, specificity and agreement rate.Univariate and multivariate analyses were performed to identify risk factors for overall survival(OS). Propensity score analysis was performed to adjust variables to control for selection bias.RESULTS: Each index could predict OS in gastric cancer patients in univariate analysis, but only PNI had independent prognostic significance in multivariate analysis before and after adjustment with propensity scoring(hazard ratio, 1.668; 95% confidence interval:1.368-2.035). In subgroup analysis, a low PNI predicted a significantly shorter OS in patients with stage Ⅱ-Ⅲ disease(P = 0.019, P < 0.001), T3-T4 tumors(P <0.001), or lymph node metastasis(P < 0.001). Canton score, a combination of PNI, NLR, and platelet, was a better indicator for OS than PNI, with the largest area under the curve for 12-, 36-, 60-mo OS and overall OS(P = 0.022, P = 0.030, P < 0.001, and P = 0.024,respectively). The maximum sensitivity, specificity, and agreement rate of Canton score for predicting prognosis were 84.6%, 34.9%, and 70.1%, respectively.CONCLUSION: PNI is an independent prognostic factor for OS in gastric cancer. Canton score can be a novel preoperative prognostic index in gastric cancer.

Combined Hangzhou criteria with neutrophillymphocyte ratio is superior to other criteria in selecting liver transplantation candidates with HBV-related hepatocellular carcinoma

BACKGROUND： The elevation of neutrophil-lymphocyte ratio （NLR） has adverse effects on the prognosis of patients with hepatocellular carcinoma （HCC） who have received liver transplantation （LT）. The Hangzhou criteria are set for selecting HCC patients for LT. The present study aimed to establish a set of new criteria combining the NLR and Hangzhou crite- ria for selecting HCC patients for LT.

Activated systemic inflammatory response at diagnosis reduces lymph node count in colonic carcinoma

AIM: To investigate a link between lymph node yield and systemic inflammatory response in colon cancer. METHODS: A prospectively maintained database was interrogated. All patients undergoing curative colonic resection were included. Neutrophil lymphocyte ratio(NLR) and albumin were used as markers of SIR. In keeping with previously studies, NLR ≥ 4, albumin < 35 was used as cut off points for SIR. Statistical analysis was performed using 2 sample t-test and χ~2 tests where appropriate.RESULTS: Three hundred and two patients were included for analysis. One hundred and ninety-five patients had NLR < 4 and 107 had NLR ≥ 4. There was no difference in age or sex between groups. Patients with NLR of ≥ 4 had lower mean lymph node yields than patients with NLR < 4 [17.6 ± 7.1 vs 19.2 ± 7.9(P = 0.036)]. More patients with an elevated NLR had node positive disease and an increased lymph node ratio(≥ 0.25, P = 0.044). CONCLUSION: Prognosis in colon cancer is intimately linked to the patient’s immune response. Assuming standardised surgical technique and sub specialty pathology, lymph node count is reduced when systemic inflammatory response is activated.

Inflammation-related indicators to distinguish between gastric stromal tumors and leiomyomas:A retrospective study

BACKGROUND Gastric leiomyomas and gastric stromal tumors are the most common types of gastric tumors encountered.In recent years,the incidence of the two types of tumors has been increasing,but the differential diagnosis is still a challenge in clinical work.However,as there are many reports on stromal tumors and inflammation-related indicators are gradually being paid attention to as important factors in predicting tumor prognosis,the two main purposes of this study were to explore the inflammation-related differences between the two types of tumors and to develop a nomogram as a predictive model.AIM To explore the differences in platelet-lymphocyte ratio(PLR),neutrophillymphocyte ratio(NLR),lymphocyte mononuclear cell ratio(LMR),and SII between the two types of tumors,and simultaneously create the nomogram model.METHODS This study enrolled 88 patients in the gastric stromal tumor group and 56 patients in the gastric leiomyoma group,and the relevant data of the two groups were entered into the system for an integrated analysis.The primary objective of this study was to identify the differences in the inflammation index between the two types of tumors.RESULTS There were statistically significant differences between the two groups in sex,age,and tumor location.In comparison,gastric leiomyomas seem to be more common in women,young patients,and gastric cardia,which is in line with our previous research;the groups showed the following statistical differences:PLR(158.2%vs 134.3%,P=0.028),NLR(2.35 vs 1.68,P=0.000),LMR(5.75 vs 10.8,P=0.004),and SII(546.2 vs 384.3,P=0.003).The results of the multivariate logistic regression analysis showed that sex,age,tumor location,and LMR were independent risk factors for the identification of the two types of tumors.After considering the risk factors selected by the above analysis into the predictive model,a predictive model for distinguishing gastrointestinal stromal tumors from gastric leiomyomas was established as the nomogram.CONCLUSION Gastric leiomyomas and gastric stromal tumors are not only different in factors such as age of the patient,but also in inflammatory indicators such as LMR and PLR.We have established a predictive model related to the laboratory indicators and are looking forward to further research conducted in this clinical area.

Risk factors for occult metastasis detected by inflammation-based prognostic scores and tumor markers in biliary tract cancer

BACKGROUND Radiological detection of small liver metastasis or peritoneal metastasis is still difficult,and some patients with biliary tract cancer(BTC)are unresectable after laparotomy.Staging laparoscopy may help avoid unnecessary laparotomy.However,which category of BTC is amenable with staging laparoscopy remains unclear.AIM To clarify the risk factors for occult metastasis in patients with BTC.METHODS Medical records of patients with BTC who underwent surgery at our institution between January 2008 and June 2014 were retrospectively reviewed.The patients were divided into two groups,according to resection or exploratory laparotomy(EL).Preoperative laboratory data,including inflammation-based prognostic scores and tumor markers,were compared between the two groups.Prognostic importance of detected risk factors was also evaluated.RESULTS A total of 236 patients were enrolled in this study.Twenty-six(11%)patients underwent EL.Among the EL patients,there were 16 cases of occult metastasis(7 liver metastases and 9 abdominal disseminations).Serum carcinoembryonic antigen level,carbohydrate antigen 19-9 level,neutrophil-lymphocyte ratio and modified Glasgow prognostic score were significantly higher in the EL group than in the resected group,and these factors were prognostic.Among these factors,carcinoembryonic antigen>7 ng/mL was the most useful to predict occult metastasis in BTC.When patients have more than three of these positive factors,the rate of occult metastasis increases.CONCLUSION Inflammation-based prognostic scores and tumor markers are useful in detecting occult metastasis in BTC;based on these factors,staging laparoscopy may reduce the rate of EL.

Folic Acid Supplementation Ameliorates Inflammation and Apoptosis in Ethanol-Induced Gastric Ulceration in Rats

Although the gastroprotective potential of folic acid has been reported, little is known about the role of inflammation and apoptosis in the said activity. This study, therefore, assessed lipid peroxidation (LPO), Neutrophil-lymphocyte ratio (NLR), C-reactive protein (CRP) as markers of inflammation and, p53 and BCl-2 as markers of apoptosis in ethanol-induced gastric ulcer pretreated with Folic acid (FA) for twenty-one (21) days. Adult male Wistar rats were arranged into experimental groups (n = 5) viz: 1) Control;2) Ulcer control;3) 2FA (2 mg/kg folic acid + Ulcer);4) 3FA (3 mg/kg folic acid + Ulcer);5) OMEP (20 mg/kg omeprazole + Ulcer);6) 2FA + OMEP + Ulcer;and 7) 3FA + OMEP + Ulcer. Ulcer score, LPO, NLR, serum CRP were all determined one hour post ulcer induction. Paraffin gastric sections were stained first with H & E, then immunostained for p53 and BCl-2. Ethanol caused gastric lesion with an index of 3.0 ± 0.2. Ulcer severity and LPO was significantly decreased in the 2FA, 3FA, OMEP, 2FA + OMEP and 3FA + OMEP groups. NLR reduced significantly in the 2FA, 3FA, OMEP and OMEP + 3FA group. Qualitatively, there was absence of C-reactive protein in the 2FA group while quantitatively, presence of CRP appeared sustained in the 3FA and OMEP treated groups. Unlike p53, the expression and labeling index of BCl-2 were significantly enhanced more in the FA and OMEP combination than OMEP alone. Folic acid ameliorates the development of gastric ulcer in rats via its anti-inflammatory and anti-apoptotic activities.
