Combining systemic inflammatory response index and albumin fibrinogen ratio to predict early serious complications and prognosis after resectable gastric cancer

BACKGROUND Gastric cancer has a high incidence and fatality rate,and surgery is the preferred course of treatment.Nonetheless,patient survival rates are still low,and the incidence of major postoperative complications cannot be disregarded.The systemic inflammatory response,nutritional level,and coagulation status are key factors affecting the postoperative recovery and prognosis of gastric cancer patients.The systemic inflammatory response index(SIRI)and the albumin fibrinogen ratio(AFR)are two valuable comprehensive indicators of the severity and prognosis of systemic inflammation in various medical conditions.AIM To assess the clinical importance and prognostic significance of the SIRI scores and the AFR on early postoperative outcomes in patients undergoing radical gastric cancer surgery.METHODS We conducted a retrospective analysis of the clinicopathological characteristics and relevant laboratory indices of 568 gastric cancer patients from January 2018 to December 2019.We calculated and compared two indicators of inflammation and then examined the diagnostic ability of combined SIRI and AFR values for serious early postoperative complications.We scored the patients and categorized them into three groups based on their SIRI and AFR levels.COX analysis was used to compare the three groups of patients the prognostic value of various preoperative SIRI-AFR scores for 5-year overall survival(OS)and disease-free survival(DFS).RESULTS SIRI-AFR scores were an independent risk factor for prognosis[OS:P=0.004;hazards ratio(HR)=3.134;DFS:P<0.001;HR=3.543]and had the highest diagnostic power(area under the curve:0.779;95%confidence interval:0.737-0.820)for early serious complications in patients with gastric cancer.The tumor-node-metastasis stage(P=0.001),perioperative transfusion(P=0.044),positive carcinoembryonic antigen(P=0.014)findings,and major postoperative complications(P=0.011)were factors associated with prognosis.CONCLUSION Preoperative SIRI and AFR values were significantly associated with early postoperative survival and the occurrence of severe complications in gastric cancer patients.

Role of fibrinogen,albumin and fibrinogen to albumin ratio in determining angiographic severity and outcomes in acute coronary syndrome

BACKGROUND Coronavirus disease 2019(COVID-19)pandemic unmasked the huge deficit in healthcare resources worldwide.It highlighted the need for efficient risk stratification in management of cardiovascular emergencies.AIM To study the applicability of the old,available and affordable nonconventional biomarkers:albumin and fibrinogen in their ability to predict angiographic severity and clinical outcomes in patients with acute coronary syndrome(ACS).METHODS In this prospective,observational study,166 consecutive patients with ACS were enrolled.Fibrinogen,albumin and their ratio were determined from serum.Patients with underlying chronic liver disease,active malignancy,autoimmune disease,active COVID-19 infection and undergoing thrombolysis were excluded.RESULTS Mean age of the population was 60.5±1.5 years,74.1%being males.ST elevation myocardial infarction(STEMI)was most common presentation of ACS seen in 57%patients.Fibrinogen albumin ratio(FAR)≥19.2,had a sensitivity of 76.9%and specificity of 78.9%[area under the receiver operating characteristic curves(AUROC)=0.8,P=0.001]to predict≤thrombolysis in myocardial infarction(TIMI)1 flow in culprit artery in STEMI patients.Even in non-STEMI patients,FAR≥18.85 predicted the same with 80%sensitivity and 63%specificity(AUROC=0.715,P=0.006).CONCLUSION Novel biomarkers,with their high cost,lack of availability and long turn over time are impractical for real-world use.Identifying≤TIMI 1 flow in the culprit artery has significant impact of management and outcome.Our study has shown that readily available biomarkers like fibrinogen and albumin can help identify these high-risk patients with good accuracy.This allows risk-stratification and individualization of treatment in ACS.

Prognostic significance of the fibrinogen-to-albumin ratio in gallbladder cancer patients

AIM To investigate the prognostic role of fibrinogen-toalbumin ratio(FAR) on patients with gallbladder cancer(Gbc) in this study.METHODS One hundred and fifty-four Gbc patients were retro-spectively analyzed, who received potentially curative cholecystectomy in our institute from March 2005 to December 2017. Receiver operating characteristic curve(ROc curve) was used to determine the optimal cut-offs for these biomarkers. In addition, Kaplan-Meier survival analysis as well as multivariate analysis were applied for prognostic analyses.RESULTS ROc curve revealed that the optimal cut-off value for FAR was 0.08. FAR was significantly correlated with age(P = 0.045), jaundice(P < 0.001), differentiation(P = 0.002), resection margin status(P < 0.001), T stage(P < 0.001), TNM stage(P < 0.001), and c A199(P < 0.001) as well as albumin levels(P < 0.001). Multivariate analysis indicated that the resection margin status [hazard ratio(HR): 2.343, 95% confidence interval(c I): 1.532-3.581, P < 0.001], TNM stage(P = 0.035), albumin level(HR = 0.595, 95%c I: 0.385-0.921, P = 0.020) and FAR(HR: 2.813, 95%c I: 1.765-4.484, P < 0.001) were independent prognostic factors in Gbc patients.CONCLUSION An elevated preoperative FAR was significantly correlated with unfavorable overall survival in Gbc patients, while an elevated preoperative albumin level was a protective prognostic factor for patients with Gbc. The preoperative FAR could be used to predict the prognosis of Gbc patients, which was easily accessible, costeffective and noninvasive.

Prognostic value of fibrinogen and D-dimer-fibrinogen ratio in resectable gastrointestinal stromal tumors

AIM To investigate the prognostic value of preoperative fbri-nogen concentration （FIB） and D-dimer-fibrinogen ratio （DFR） in gastrointestinal stromal tumors （GISTs）.METHODS The purpose of this study was to retrospectively ana-lyze 170 patients with GISTs who were admitted to our hospital from January 2010 to December 2015. The op-timal cutoff values of related parameters were estimated by receiver operating characteristic （ROC） curve analysis. The recurrence free survival （RFS） rate was evaluated using Kaplan-Meier curves. Univariate analysis and multivariate Cox regression models were used to analyze the prognostic factors of GISTs. The relationship between the FIB, D-dimer, DFR, platelet count （PLT）, and the clinicopathological features of GISTs was described by the chi-square test or nonparametric rank sum test （Mann-Whitney test）.RESULTS In ROC analysis, the optimal cutoff values of FIB, D-dimer, DFR, and PLT were 3.24 g/L, 1.24 mg/L, 0.354, and 197.5 （× 109/L）, respectively. Univariate analysis and the Kaplan-Meier survival curve showed that FIB, D-dimer, DFR, PLT,National Institutes of Health （NIH） risk category, tumor size, tumor location, and mitotic index were signifcantly relevant to the 3-year and 5-year survival rate of patients （ P 〈 0.05）. Cox multivariate regression analysis illustrated that FIB （RR： 0.108, 95%CI： 0.031-0.373）, DFR （RR： 0.319, 95%CI： 0.131-0.777）, and NIH risk category （ RR： 0.166, 95%CI： 0.047-0.589） were independent prognostic factors of the RFS rate （ P 〈 0. 05）. Moreover, FIB, D-dimer, DFR, and PLT were correlated with the clinical features of GISTs.CONCLUSIONFIB, D-dimer, DFR, and PLT are all related to the prognosis of GISTs. Moreover, FIB and DFR may be independent risk factors for predicting the prognosis of resectable GISTs.

Prognostic significance of combined fibrinogen concentration and neutrophil-to-lymphocyte ratio in patients with resectable non-small cell lung cancer

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.
