To evaluate the predicted value of neutrophil-to-lymphocyte ratio (NLR) in the diagnosis of early prostate cancer by using standardized Full blood count (FBC) performed within 4 weeks before biopsy and histology results from transperineal prostate biopsy (RTPB).Patients who underwent RTPB under general anesthesia (GA), at Urology Department, Singapore General Hospital between September 2006 and Febuary 2016 were retrospectively reviewed.NLR was calculated using full blood count (FBC) that was done as a pre-admission test before GA within 4 weeks before the biopsy. Statistical analyses were done to establish the correlation of NLR and different clinical parameters such as biopsy histology, pre-biopsy PSA, and prostate volume.A total of 652 patients who underwent RTPB for diagnostic purposes with a valid PSA level were included in this study. There was total of 409 (62.7%) benign histology and 243 (37.3%) prostate cancer. There was no significant difference in median NLR between the benign and prostate cancer group (2.00 vs 1.99; P = .29).In the subgroups analysis, there was also no significant difference of median NLR value in clinical significant cancer (defined as Gleason 3 + 4 and above) and benign histology group (NLR 2.00 vs 2.01, P = .41), as well as prostate cancer and benign group according to different pre-biopsy PSA levels: PSA (ug/l) < 4, 4 to 10, 10 to 20, and >20, respectively. (Median NLR 1.34 vs 1.76; 1.97 vs 1.97; 1.97 vs 2.18; 2.18 vs 1.98, P > .05). NLR is neither associated with prostate cancer using logestic regression model nor a strong predictor of the Gleason grade group and D’Amico risk stratification group using ordinal regression model. (P > .05)There was no statistically significant difference of NLR between the benign and prostate cancer group as a whole or in the subgroup analyses for patients who underwent robotic transperineal prostate biopsy. NLR may have a limited role in predicting early-stage prostate cancer. 相似文献

AIM: To evaluate the accuracy of red cell distribution width (RDW) to platelet ratio (RPR) to predict in-hospital mortality in acute pancreatitis (AP).METHODS: Between January 2010 and June 2012, 102 patients with AP were recruited to the study. In this retrospective cohort study, for all subjects, demographic data on hospital admission, AP etiology, co-morbid diseases, organ failure assessment, laboratory parameters and length of hospital stay were examined. Additionally, we used a non-invasive prediction method in addition to the RPR to evaluate the disease severity. Multivariate logistic regression analyses were used to evaluate the impact of RPR on hospital admission to predict mortality.RESULTS: The male-female ratio (59/43) was 1.37 with a median age of 56.5 years (17-89 years). In both univariate and multivariate analyses, RDW and RPR were presented as independent and significant variables on admission to predict mortality. The RPR obtained on hospital admission was persistently higher among non-survivors than among survivors (P < 0.0001). The median RPR was 0.000087 in the non-survivor group and 0.000058 in the survivor group. RPR with a cutoff value of 0.000067 presented an area under the curve of 0.783 (95%CI: 0.688-0.878) in receiver operating characteristic curves and could predict the mortality of approximately 80% of the patients.CONCLUSION: We identified RPR as a valuable, novel laboratory test to predict mortality in AP. 相似文献

Malnutrition is an important condition in patients diagnosed with chronic obstructive pulmonary disease (COPD). There is a need for practical and objective nutritional assessment methods in patients hospitalized in the intensive care unit with the diagnosis of COPD. In this study, it was aimed to determine the parameters that can practically evaluate the nutritional status of these patients. It was aimed to determine the relationship between prognostic nutritional index (PNI), and nutritional risk screening (NRS)-2002, nutrition risk in the critical ill (Nutric) Score and to determine a cut-off value for PNI, neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and other complete blood count parameters.Hemogram values, albumin values, NLR, PLR, LMR, NRS-2002, PNI and modified Nutric Score calculations of the patients hospitalized in the intensive care unit due to COPD were recorded. The relationship between PNI and NRS-2002 and modified Nutric Score, as well as the relationship between NLR, PLR, LMR, hemogram parameters and PNI were analyzed using statistical methods.The PNI cut-off value for nutritional assessment in patients hospitalized in the intensive care unit due to COPD was determined as 38.5 (area under curve = 0.891, sensitivity 80.8%, specificity 88.1%, positive predictive value 92.9%, negative predictive value 88%). High-risk group according to PNI compared to low-risk group, lymphocyte count (P < .001), basophil count (P = .004), red blood cell (P < .001), hemoglobin (P < .001), hematocrit (P < .001), and LMR (P = .001) were statistically significantly lower, while NLR (P < .001) and PLR (P = .001) were statistically significantly higher. Cut-off values for lymphocyte count, basophil count, NLR, PLR, and LMR were found to be 1.18, 0.035, 7.97, 291.10, and 2.606, respectively.Nutritional risk assessment can be made in a practical way by using PNI in patients hospitalized in intensive care unit due to COPD. For this, the PNI cut-off value was determined as 38.5 in our study. In addition, NLR, PLR, LMR, basophil and lymphocyte values, which can be calculated using complete blood count parameters, may also be useful in the evaluation of nutritional status in these patients. In our study, the cut-off values determined for NLR, PLR, LMR, basophil and lymphocyte were 7.97, 291.10 and 2.606, 0.035 and 1.18, respectively. We think that the results we have obtained can provide preliminary information for future research. 相似文献

Background
The red blood cell distribution width (RDW) is a rather simple measure of red blood cell (RBC) size heterogeneity (i.e., anisocytosis), which is easily calculated by dividing the standard deviation (SD) of erythrocyte volumes for the mean corpuscular volume (MCV). Emerging evidence suggests that, besides RBC abnormalities, many human disorders may be frequently associated with a high degree of anisocytosis.Methods
In this narrative review, we analyzed the current scientific literature about the putative role and the potential epidemiologic association between RDW and cardiovascular diseases. The findings of the most representative epidemiological studies were summarized and discussed.Results
Overall, considerable and convincing evidence has been brought that an increased RDW value is associated with acute coronary syndrome (ACS) [including acute myocardial infarction (AMI)], ischemic cerebrovascular disease (including stroke), peripheral artery disease (PAD), as well as with atrial fibrillation (AF), heart failure (HF) and hypertension. Higher anisocytosis also significantly and independently predicts adverse outcomes in patients with these conditions.Conclusions
Although the role of anisocytosis in the pathogenesis of cardiovascular diseases remains uncertain, the considerable evidence available so far suggests that the clinical use of RDW may be broadened beyond the conventional boundaries of erythrocyte disorders, in particular for assisting the diagnosis and prognostication of patients with ACS, ischemic cerebrovascular disease, PAD, HF and AF. 相似文献10.

AimRed blood cell distribution width (RDW) is a marker of cardiovascular morbidity and mortality. However, there is little data on the relationship between RDW and diabetes-associated complications. The aim was to investigate whether there is any association between RDW, nephropathy, neuropathy and peripheral arterial disease (PAD) in a type 2 diabetic population.MethodsThis study included 196 diabetic patients with proliferative diabetic retinopathy. All subjects were investigated for diabetic nephropathy, diabetic neuropathy and PAD. Participants underwent 24-h blood pressure monitoring and were analysed for markers of the metabolic syndrome, inflammation, and insulin resistance.Results57% of the participants had diabetic nephropathy, 46% had diabetic neuropathy while 26% had PAD. No significant association was found between RDW, diabetic neuropathy and PAD (p = NS). However, RDW was strongly associated with diabetic nephropathy (p = 0.006), even following adjustment for potential confounding variables. Multivariate logistic regression analysis showed RDW (odds ratio [OR] 1.64, 95% confidence interval [CI] 1.15–2.35, p = 0.006), estimated glomerular filtration rate (OR 0.98, 95% CI 0.96–0.99, p < 0.001), night-time diastolic blood pressure (OR 1.07, 95% CI 1.03–1.11, p = 0.001) and erythrocyte sedimentation rate (OR 1.03, 95% CI 1.004–1.05, p = 0.019) to be independently associated with diabetic nephropathy.ConclusionsThis is the first study to report lack of association between RDW, neuropathy and PAD in subjects with type 2 diabetes mellitus. More importantly, RDW was shown to be significantly associated with diabetic nephropathy in a type 2 diabetic population with advanced proliferative retinopathy independent of traditional risk factors, including diabetes duration and glycaemic control. 相似文献

BackgroundLung cancer contributes significantly to the total of cancer-linked deaths globally, accounting for 1.3 million deaths each year. Preoperative albumin (Alb) concentration and neutrophil-to-lymphocyte ratio (NLR) may reflect chronic inflammation and be used to predict lung cancer outcomes.MethodsThe clinical records of 293 patients with non-small cell lung cancer (NSCLC) in Fujian Medical University Cancer Hospital & Fujian Cancer Hospital were reviewed retrospectively in this current study. Clinicopathologic pretreatment, including NLR, Glasgow prognostic score (GPS), and post-treatment value, such as tumor-node-metastasis (TNM) were documented. The cut-off finder application was employed to calculate the optimal threshold values. The significance of Alb concentration combined with NLR (COA-NLR) on the prediction of overall survival (OS) was explored using Kaplan-Meier analysis along with Cox proportional hazards.ResultsThe results revealed that COA-NLR could independently assess the OS of patients with NSCLC [hazard ratio (HR) =1.952, 95% confidence interval (CI): 1.367 to 2.647, P<0.001]. Moreover, the 3-year OS rates were 87.2%, 68.5%, and 52.8% for the COA-NLR =0, COA-NLR =1, and COA-NLR =2, respectively (P<0.001).ConclusionsPreoperative COA-NLR value can effectively stratifies prognosis in NSCLC patients by classified patients into three independent groups. It can be adopted as an effective biomarker for prognosis in NSCLC patients treated with resection. 相似文献

Peripheral blood of Neutrophil-to-Lymphocyte ratio (NLR), carcinoma embryonic antigen (CEA), cancer antigen 125 (CA125) and cancer antigen 15–3 (CA15-3) could be used as prognostic indicators for several types of tumors. The purpose of this study was to evaluate the predictive value of inflammatory cell ratio and tumor markers for postoperative breast cancer patients. Clinical data concerning 190 breast cancer patients who underwent radical surgery in Zhejiang Provincial Hospital of Chinese Medicine from 2013 and 2016 were retrospectively analyzed. The effects of NLR, CEA, CA125, and CA153 on the disease-free survival (DFS) of patients with breast cancer were analyzed by χ2 test and Cox regression analyses. There were totally 32 of 190 patients had local or distant metastases within 5 years after surgery. The peripheral blood NLR, CEA, CA125, and CA15-3 areas under the curve (AUC) were 0.8272, 0.667, 0.702, and 0.715, and the optimal cutoff values were 2.65, 1.47, 10.55, and 10.55, respectively. Univariate analysis and Kaplan-Meier survival analysis revealed that the serum NLR, CEA, CA125, and CA15-3 were related to postoperative 5-year DFS (P < .05). In addition, multivariate survival analysis identified the following independent prognostic factors: NLR (P < .001), CA125 (P = .045) and ki-67 (P = .020). Preoperative serum inflammatory biomarker of NLR and tumor marker of CA125 have potential prognostic value for breast carcinoma. 相似文献

Background:Prior reports have suggested that the red blood cell distribution width (RDW) parameter could be measured as a prognostic indicator in pulmonary embolism (PE) patients, thereby helping to guide their care. However, no systematic analyses on this topic have been completed to date, and the exact relationship between RDW and PE remains to be fully clarified. We will therefore conduct a systematic literature review with the goal of defining the correlation between RDW and mortality in acute PE cases.Methods:The EMBASE, Web of Knowledge, PubMed, ClinicalTrials.gov, and Cochrane Library databases will be searched for all relevant studies published from inception through March 2021 using the following search strategy: (“red blood cell distribution width”) AND (“pulmonary embolism”). Two authors will independently identify eligible studies and extract data. The Q and I2 statistics will be used to judge heterogeneity among studies.Results:This study will establish the relative efficacy of RDW as a metric for predicting PE patient mortality.Conclusions:This study will offer a reliable, evidence-based foundation for the clinical utilization of RDW as a tool for gauging mortality risk in acute PE patients.Ethics and dissemination:As this is a protocol for a systematic review of previously published data, no ethical approval is required. Electronic dissemination of study results will be done through a peer-review publication or represented at a related conference. 相似文献
