The role of preoperative neutrophil–lymphocyte and platelet–lymphocyte ratio in patients after radical resection for gastric cancer

Abstract

The objective of this study was to investigate the impact of neutrophil–lymphocyte ratio (NLR) and the platelet–lymphocyte ratio (PLR) on the postoperative complication and long-term outcomes in patients with resectable gastric cancer (GC). A total of 377 patients who underwent curative resection for GC were enrolled. In logistic analysis, PLR (p?=?0.09) was independently associated with the incidence of postoperative complication. The results of multivariate survival analysis showed the NLR and PLR were introduced as prognostic factors for operable GC, the NLR may represent a useful prognostic index for the prediction of overall survival (OS) in advanced GC (p?=?0.021).

Clinical implication of pretreatment neutrophil to lymphocyte ratio in soft tissue sarcoma

Introduction: Elevated neutrophil to lymphocyte ratio has been identified as a prognostic indicator in malignancies whereas; its association with extremity and trunk soft tissue sarcoma remain unclear. The aim of this study is to determine the utility of full blood neutrophil lymphocyte ratio (NLR) in preoperative diagnosis and its predictive value for survival in patients managed for soft tissue sarcoma of the trunk and extremities.

Method: 223 patients who presented with a soft tissue tumor were retrospectively reviewed. The study period was from January 2002–December 2009. Preoperative NLR as well as demographics, clinical and histopathological data were analysed.

Results: Full blood NLR was significantly higher in patient with a soft tissue sarcoma compared to benign soft tissue tumors (p < 0.001). Cox regression analysis demonstrated that elevated NLR >5 (p < 0.05) may be an adverse prognostic factor for Overall Survival.

Conclusion: The preoperative NLR is a simple, investigation predicting the preoperative diagnosis of a soft tissue sarcoma and a predictor of worse overall survival for patient with a soft tissue sarcoma.     

Clinical significance of preoperative neutrophil-lymphocyte versus platelet-lymphocyte ratio in patients with operable colorectal cancer

The objective of this study was to clarify whether the neutrophil-lymphocyte ratio (NLR) and the platelet-lymphocyte ratio (PLR) are significant prognostic markers in patients with resectable colorectal cancer (CRC). A total of 200 patients who underwent curative resection for CRC were enrolled. The NLR and PLR were positively correlated (p?<?0.001). Both the NLR and PLR were shown to be good prognostic biomarkers of overall survival (OS) (p?=?0.002 and p?=?0.001, respectively). The PLR was an independent prognostic factor of OS based on multivariate analysis (hazard ratio, 1.971; 95% confidence interval, 1.102–3.335; p?=?0.021).     

Elevated neutrophil to lymphocyte ratio predicts survival in advanced pancreatic cancer

Background: Elevated neutrophil to lymphocyte ratio (NLR) is linked with worse survival in many malignancies, whereas its association with pancreatic cancer (PC) remains unclear.

Methods: We retrospectively reviewed 95 patients with locally advanced or metastatic PC receiving gemcitabine-based chemotherapy. The prognostic value of NLR was evaluated.

Results: Elevated pretreatment NLR (>5) was observed in 16 out of 89 eligible patients, which was identified as an independent prognostic factor for overall survival (OS). The median OS for patients with elevated and normal NLR were 2.4 months and 7.7 months, respectively (p <0.001).

Conclusions: Elevated NLR is a predictor of shorter survival in patients with advanced PC.

Plasma levels of pentraxin 3 in patients with spondyloarthritis

Context: Determining the disease’s inflammatory activity in spondyloarthritis (SpA) is difficult although very important as it is this that drives treatment.

Objective: To investigate if plasma pentraxin-3 (PTX3) could act as an inflammatory marker in SpA.

Methods: Eighty one SpA patients (11 with psoriatic arthritis (PsoA) and 70 with ankylosing spondylitis (AS)) and 90 gender and age paired controls were studied for plasma PTX3 levels by ELISA. Patients had determinations of disease activity through C reactive protein (CRP), erythrocyte sedimentation rate (ESR), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Ankylosing Spondylitis Disease Activity Score (ASDAS)-CRP. Epidemiological, clinical and treatment data were collected through chart review.

Results: SpA patients had lower concentrations of plasma PTX3 than controls (median of 0.95?ng/mL vs 1.64?ng/mL; p?p?=?0.42). Uveitis, presence of HLA B27, tobacco exposure, age and disease duration did not influence PTX3 levels.

Conclusions: PTX3 plasma levels do not reflect disease activity in SpA. However, it probably participates in the ethiopathogenetic process, as it is consumed in these patients.

Relationships of Different Blood Pressure Categories to Indices of Inflammation and Platelet Activity in Sustained Hypertensive Patients with Uncontrolled Office Blood Pressure

Failure to decrease blood pressure (BP) normally during nighttime (non-dipping) in hypertension is associated with higher cardiovascular morbidity and mortality. In addition, non-dipping BP is associated with increased platelet activity and inflammatory response; however, there has been no study to evaluate the relationship of non-dipping BP to indices of platelet activity and inflammation in uncontrolled hypertensive patients. In the present study, hypertensive subjects with uncontrolled office BP were firstly divided into three groups: 84 subjects with white coat effect and 365 subjects with true uncontrolled hypertension. Then, true uncontrolled hypertensive patients were divided into two groups: 158 patients with dipping and 207 patients with non-dipping. Mean platelet volume (MPV), uric acid (UA), γ-glutamyltransferase (GGT), C-reactive protein (CRP), and high-sensitivity CRP (hs-CRP) levels were studied. The general characteristics and risk factors for coronary artery disease (CAD) of the study population were similar among the groups. MPV, UA, GGT, CRP, and hs-CRP levels were significantly higher in non-dipper group than both dipper and white coat effect groups, and were significantly higher in dipper group than in white coat effect group (MPV: 9.1?±?1.3, 8.7?±?1.1, and 8.0?±?0.9 fL; UA: 6.9?±?1.2, 5.9?±?1.4, and 4.1?±?0.8?mg/dL; GGT: 38.9?±?11.1, 33.6?±?14.9, and 25.2?±?9.2 U/L; CRP: 7.1?±?2.4, 6.2?±?1.9, and 3.9?±?0.8?mg/dL; hs-CRP: 3.8?±?1.5, 3.3?±?1.2, and 2.0?±?0.6, non-dipper, dipper, and white coat effect groups, respectively, all p values <0.01). All study parameters strongly correlated with each other. In conclusion, in hypertensive patients with uncontrolled office BP, presence of non-dipping BP is associated with increased platelet activity and inflammation, which can be one of the underlying plausible mechanisms of non-dipping BP status.     

Clinical prognostic evaluation of immunocytes in different molecular subtypes of breast cancer

To retrospectively analyze the relationship between preoperative blood parameters and postoperative clinical outcomes in patients with different molecular subtypes of breast cancer (BC), a cohort of 601 patients with BC in the Third Affiliated Hospital, Sun Yat-sen University, was retrospectively reviewed. They were categorized into four subtypes according to the expression of ER, PR, HER-2, and KI-67%. White blood cell, neutrophil, lymphocyte, monocyte, eosinophil, basophil, and platelet counts, the neutrophil-to-lymphocyte ratio (NLR), the neutrophil-to-monocyte ratio (NMR), the lymphocyte-to-monocyte ratio (LMR), and the platelet-to-lymphocyte ratio (PLR) were recorded. Univariate and multivariate analyses were performed to identify the relationship between parameters and ratios and disease-free survival (DFS) and overall survival (OS). Luminal subtypes of BC had smaller tumor volume, better differentiation degree of invasive ductal carcinoma, less lymph node metastasis, and better clinical outcome than the HER-2 overexpression and triple-negative BC (TNBC) subtypes. In multivariate analysis, age and LMR were the independent prognostic factors of DFS in patients with luminal A (age, p = 0.005; LMR, P = 0.026); PLR in patients with luminal B (DFS; p = 0.032; OS, p= 0.012); LMR in patients with HER-2 overexpression (DFS; p = 0.008; OS, p = 0.017); and NLR for DFS (p = 0.014); and WBC for OS (p = 0.008) in patients with TNBC. LMR was the benign predictor of luminal A and HER-2 overexpression. PLR was the adverse predictor of luminal B. WBC and NLR were the adverse predictors of TNBC. Therefore, these peripheral blood parameters can play an important role in the diagnosis and treatment of patients with different molecular subtypes of BC.     

Plasma soluble urokinase plasminogen activator receptor (suPAR) levels in systemic lupus erythematosus

Objective: Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker of systemic inflammation. We aimed to characterize plasma suPAR levels in SLE patients.

Methods: We measured plasma suPAR, C reactive protein (CRP) and erythrocyte sedimentation rate (ESR) in 89 SLE patients and 29 healthy controls.

Results: suPAR and ESR values were higher in SLE than in controls, while CRP levels were comparable. ROC analysis of suPAR levels indicated a cut-off value of 5.70?ng/mL to distinguish patients with high disease activity (SLEDAI >8).

Conclusion: suPAR might be an objective marker for identifying SLE patients with active disease.

The predictive value of a preoperative systemic immune-inflammation index and prognostic nutritional index in patients with esophageal squamous cell carcinoma

Growing evidence indicates that systemic inflammation response and malnutrition status are correlated with survival in certain types of solid tumors. The aim of this study is to evaluate the association between the systemic immune-inflammation index (SII) and prognostic nutritional index (PNI) and overall survival (OS) in patients with esophageal squamous cell carcinoma (ESCC) after esophagectomy. A consecutive series of 655 patients with resected ESCC who underwent esophagectomy were enrolled in the retrospective study. The preoperative SII was defined as platelet × neutrophil/lymphocyte counts. The PNI was calculated as albumin concentration (g/L) + 5 × total lymphocyte count (10⁹/L). The optimal cut-off values of SII, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and PNI were determined by receiver operating characteristic analysis. Survival analysis was performed using the Kaplan–Meier method with a log-rank test, followed by a multivariate Cox proportional hazards model. A high SII was significantly related to tumor size, histological type, invasion depth, and TNM stage (p < 0.05). A low PNI was significantly associated with age, tumor size, invasion depth, lymph node metastasis, and TNM stage (p < 0.05). Univariate analysis revealed that age, smoking history, tumor size, invasion depth, lymph node metastasis, SII, NLR, PLR, and PNI were predictors of OS (p < 0.05). Multivariate analysis identified age (p = 0.041), tumor size (p = 0.016), invasion depth (p < 0.001), lymph node metastasis (p < 0.001), SII (p = 0.033), and PNI (p = 0.022) as independent prognostic factors correlated with OS. There was a significant inverse relationship between the SII and PNI (r = 0.309; p < 0.001). The predictive value increased when the SII and PNI were considered in combination. Our results demonstrate that the preoperative high SII and low PNI are powerful indicators of aggressive biology and poor prognosis for patients with ESCC. The combination of SII and PNI can enhance the accuracy of prognosis.     

Pneumoproteins and markers of inflammation and platelet activation in the blood of grain dust exposed workers

Abstract

Purpose: To investigate if blood biomarkers could indicate early signs of lung damage or cardiovascular risk due to exposure to grain dust.

Materials and methods: Pneumoproteins and markers of inflammation and platelet activation were analysed in blood samples of 102 grain elevator and compound feed mill workers. Differences between exposed (n?=?67) and controls (n?=?35), and associations with exposure measurements and respiratory health were investigated by multiple linear regression analyses.

Results: Concentrations of CC-16 and IL-6 were higher in exposed workers compared with controls (p?<?0.001 for both), whereas fibrinogen was lower (p?=?0.005). Concentrations of CRP, TNF-α, sCD40L and sP-selectin were similar in both groups. Serum CC-16 was significantly higher in workers with farm childhood, regardless of exposure. The impact of farm childhood on CC-16 interacted with smoking. None of the biomarkers were associated with exposure measurements or any of the tested respiratory health parameters.

Conclusion: Dust exposure induced inflammatory and anti-inflammatory reactions, but did not induce systemic inflammation and had no effect on platelet activation. No cause–effect relationship could be established in spite of relatively high exposure levels, particularly to endotoxin. Whether increased serum CC-16 is an early sign of lung damage or a reversible defense reaction remains unclear.
