The prognostic value of inflammation markers in postoperative gliomas with or without adjuvant treatments

Recent studies have shown that some inflammatory markers are associated with the prognosis of solid tumors. This study aims to evaluate the prognosis of glioma patients with or without adjuvant treatment using the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR).All patients who were diagnosed with gliomas at the first and second affiliated hospital of Guangxi Medical University between 2011 and 2020 were included in this study. The optimal cutoff value of SII, NLR, and PLR was determined by X-tile software program. We stratified patients into several groups and evaluated the progression-free survival (PFS) and overall survival (OS) of SII, NLR, and PLR during the period of pre-surgical, con-chemoradiotherapy, and post-treatments. Multivariate Cox regression analyses were performed to detect the relationships between OS, PFS, and prognostic variables.A total of 67 gliomas patients were enrolled in the study. The cutoff values of SII, NLR, and PLR were 781.5 × 10⁹/L, 2.9 × 10⁹/L, and 123.2 × 10⁹/L, respectively. Patients who are pre-SII < 781.5 × 10⁹/L had better PFS (P = .027), but no difference in OS. In addition, patients who had low pre-NLR (<2.9 × 10⁹/L) meant better OS and PFS. PLR after adjuvant treatments (post-PLR) was significantly higher than pre-PLR (P = .035). Multivariate analyses revealed that pre-SII, pre-NLR were independent prognostic factors for OS (pre-SII: HR 1.002, 95% CI: 1.000–1.005, P = .030 and pre-PLR: HR 0.983, 95% CI: 0.973–0.994, P = .001), while pre-PLR was an independent factor for PFS (HR 0.989, 95% CI: 0.979–1.000, P = .041).High pre-SII or high pre-NLR could be prognostic markers to identify glioma patients who had a poor prognosis.

目的研究簇集蛋白(CLU)、Nod样受体蛋白3(NLRP3)和趋化因子(FKN)联合检测对老年糖尿病患者动脉粥样硬化性心血管病(ASCVD)的预测作用。方法选择2019年1月~2020年3月内蒙古自治区巴彦淖尔市医院收治的180例糖尿病患者,根据冠状动脉造影结果,将患者分成糖尿病组82例和ASCVD组98例,同时选择同期在本院体检的60例健康者为对照组。比较3组受试者血清CLU、NLRP3和FKN水平,通过单因素分析和基于偏最大似然估计前进法logistic回归分析ASCVD发生的预测价值,应用ROC曲线评估不同评分系统单独及联合预测ASCVD发生的价值。结果 logistic回归分析显示,CLU、FKN和NLRP3是影响ASCVD发生的危险因素(P<0.01)。ROC曲线分析表明,血清CLU单独预测最佳临界值为65.01 mg/L,敏感性为70.41%,特异性为66.20%,曲线下面积(AUC)为0.801(95%CI:0.750~0.852);血清FKN单独预测临界值为366.45 ng/L,敏感性为69.39%,特异性为65.49%,AUC为0.760(95%CI:0.707~0.812);NLRP3单独预测临界值为0.93,敏感性为60.20%,特异性为59.86%,AUC为0.631(95%CI:0.564~0.698);联合检测最佳截断值对应的敏感性、特异性和AUC分别为84.69%、69.72%和0.869(95%CI:0.831~0.907);联合预测的敏感性和AUC均明显高于单独预测。结论血清CLU、NLRP3和FKN单独和联合诊断可应用于预测ASCVD,值得临床进一步研究并推广。     

Prognostic impact of preoperative NLR and CA19-9 in pancreatic cancer

BackgroundRecently, several preoperative proinflammatory markers and nutritional factors such as neutrophil-to-lymphocyte ratio (NLR) and prognostic nutrition index (PNI) have been reported as significant predictor for poor prognosis of various malignant tumors. In this study, we evaluated the prognostic values of these preoperative parameters in patients with resectable pancreatic head cancer.MethodsWe retrospectively reviewed consecutive patients who underwent PD for pancreatic head cancer between 2007 and 2012. A total of 46 patients were enrolled in this analysis. Preoperative parameters such as CRP, CA19-9, NLR and PNI at the time of presentation were recorded as well as overall survival. Cancer specific survival was assessed using Kaplan–Meier method. Univariate and multivariate Cox regression models were applied to evaluate the prognostic relevance of preoperative parameters. The correlations between CA19-9 values, NLR and pathological findings, first recurrence site were respectively reviewed.ResultsIn multivariable analysis preoperative high NLR (≧2.7) and high CA19-9 (≧230) were independent prognostic factors for poor survival (P value: 0.03 and 0.025, respectively). Kaplan–Meier survival analysis demonstrated the overall 2-year survival rate in patients with high NLR or high CA19-9 were 37.5% compared with 89.9% in patients with low NLR and low CA19-9.ConclusionPreoperative NLR and serum CA19-9 offer significant prognostic information associated with overall survival following PD in the patients with pancreatic head cancer.     

Clinical pertinence of neutrophil-to- lymphocyte ratio among hypertensives with different grades and duration of hypertension – an insight

Over the recent years, the pathophysiology of the inflammatory component in hypertension has been a challenge, because this inflammatory response is mainly contributed by an increased oxidative stress with the release of inflammatory mediators. Identification of a simple and early inflammatory marker such as the neutrophil-to-lymphocyte ratio (NLR) is the need of the hour. This study correlates the same specifically taking into account the duration and the grades of hypertension.

Objective: The response of the NLR among the hypertensives and its correlation with duration and stages of hypertension.

Method: Totally, 80 subjects and 40 controls of age between 20 and 60 years and both genders were included. Three recordings of blood pressure were measured with a standard mercury sphygmomanometer. The differential leukocyte count was estimated with an automated Beckman Coulter.

Objective: Variations in the neutrophil and lymphocyte counts were significant among the hypertensives with a p-value < 0.001. The NLR was also significantly altered among the hypertensives with a p-value = 0.001. The NLR showed a rise in value among the normotensives, prehypertensives, and stage 1 of systolic hypertension, though not statistically significant. An increase in the NLR was observed in hypertensives with duration of 1–2 years.

Conclusion: Our study gives a new insight with a rise in NLR in early years and even among prehypertensives and stage 1 systolic hypertension under strict criterion. This could be utilized as an early predictive tool, relating the inflammatory process and hypertension which on further intervention could slow the progression of the disease process.
