D-dimer level in cancer patients is associated with risk of venous thromboembolism and deep venous thrombosis. Most cancer patients have "abnormal" D-dimer levels based on the current normal reference range. To investigate tumor-specific D-dimer reference range, we compared D-dimer levels for nine different tumour types with healthy controls by using simultaneous quantile regression and constructing a median, 5th percentile, and 95th percentile model of normal tumour D-dimer concentration. Associations with tumour primary site, stage, pathological type, and treatment were also explored...

The ErbB family of tyrosine kinase receptors is a key element in preserving cell growth homeostasis. This family is comprised of four single-transmembrane domain proteins designated ErbB-1-4. Ligand binding initiates dimerization followed by tyrosine phosphorylation and signaling, which when uncontrolled lead to cancer. Accordingly, extensive research has been devoted to finding ErbB-intercepting agents, directed against ErbB-1 and ErbB-2, but so far, no inhibitor has targeted the transmembrane domain (TMD), which is instrumental for receptor dimerization and activation...

BACKGROUND: Severe acute pancreatitis (SAP) remains a clinical challenge with considerable morbidity and mortality. An early identification of infected pancreatic necrosis (IPN), a life-threatening evolution secondary to SAP, is obliged for a more preferable prognosis. Thus, the present study was conducted to identify the risk factors of IPN secondary to SAP. METHODS: The clinical data of patients with SAP were retrospectively analyzed. Univariate and multivariate logistic regression analyses were sequentially performed to assess the associations between the variables and the development of IPN secondary to SAP...

BACKGROUND: High Neutrophil/Lymphocyte ratio (NLR), as a measure of enhanced inflammatory response, has been negatively associated with prognosis in patients with localized pancreatic ductal adenocarcinoma (PDA). OBJECTIVE: In the present study, we aimed at investigating the prognostic value of NLR in two homogeneous groups of chemotherapy-naïve metastatic PDA patients. Patients were treated with either gemcitabine (GEM) or gemcitabine/oxaliplatin (GEMOXA). We also assessed whether NLR could identify patients benefiting from the use of oxaliplatin...

Stroke is a dramatic complication of pancreatic cancer with mechanisms related to oncological disease. A better description of the characteristics of cerebrovascular events would help better understand the pathogeny and protect vulnerable patients. We thus conducted a descriptive analysis of clinical, biological, and radiological features of patients from our centers and literature.We reviewed consecutive cases of patients who presented cerebrovascular events and pancreatic cancer in 4 stroke units in Lorrain (France) between January 1, 2009 and March 31, 2015, and all reported cases of literature...

Pancreatic cancer is among the leading causes of cancer death in the USA, with limited effective treatment options. A major contributor toward the formation and persistence of pancreatic cancer is the dysregulation of the hepatocyte growth factor (HGF)/Met (HGF receptor) and the macrophage-stimulating protein (MSP)/Ron (MSP receptor) systems. These systems normally mediate a variety of cellular behaviors including proliferation, survival, and migration, but are often overactivated in pancreatic cancer and contribute toward cancer progression...

To examine the impact of plasma D-dimer levels in predicting 3-year survival and nonresectability in pancreatic cancer patients. Ninety-five patients were divided into three groups according to plasma D-dimer levels. Kaplan-Meier survival curves and hazard ratios were computed, and diagnostic indices of D-dimer in the prediction of resectability were assessed. The median survival among patients with low, medium and high D-dimer levels was 13.7 [95% confidence interval (CI): 10.2-19.6], 6.2 (95% CI: 2.0-15.1) and 2...

INTRODUCTION: Venous thrombo-embolic events (VTE) occur frequently in patients with pancreatic cancer and contribute to elevated morbidity and mortality. Clinical risk factors for thrombosis such as cancer stage and tumor grade have been clearly identified. Recently, several biomarkers have been proposed which may help identifying cancer patients at high risk of thrombosis. Those biomarkers have been studied in heterogeneous cohorts of patients with different cancer types. AIM: To compare pro-thrombotic biomarkers in pancreatic cancer and in chronic pancreatitis to determine whether these biomarkers are related to cancer or inflammation and to validate their association with thrombotic risk in a pancreatic cancer population...

The study was performed in a group of 25 patients with acute necrotizing pancreatitis (mean age 46.2 ± 6.74 years). Gender differences of the hemostasis postagressive early response in the early stages of the disease were identified by comparing the procoagulant , anticoagulant and fibrinolytic blood activity of men and women suffering from pancreatitis. Compared to men, women showed higher concentrations of fibrinogen, D-dimer and VWF and smaller values marked trombokrit , antithrombin III, inhibitor of plasmin and protein C (p < 0...

UNLABELLED: We have identified previously undiscovered BRAF in-frame deletions near the αC-helix region of the kinase domain in pancreatic, lung, ovarian, and thyroid cancers. These deletions are mutually exclusive with KRAS mutations and occur in 4.21% of KRAS wild-type pancreatic cancer. siRNA knockdown in cells harboring BRAF deletions showed that the MAPK activity and cell growth are BRAF dependent. Structurally, the BRAF deletions are predicted to shorten the β3/αC-helix loop and hinder its flexibility by locking the helix in the active αC-helix-in conformation that favors dimer formation...

BACKGROUND: A number of experimental studies have been put forth suggesting an important role of the hemostatic system in acute pancreatitis (AP) in the recent past. However, meaningful studies on clinical values of parameters of the hemostatic system in predicting pancreatitis associated complications are still scarce. In the current investigation, we evaluated the role of D-dimer to predict the severity of acute pancreatitis on day 1 of admission to the hospital. METHODS: A total of 160 subjects (75 mild AP + 35 severe AP + 50 healthy controls) were examined in the study...

REVIEW
Ingrid Pabinger, Florian Posch
Cancer patients are at an increased risk of venous thromboembolism. The clotting system is activated in most cancer patients, which is reflected by specific parameters such as an increased thrombin generation and elevated D-dimer levels. Blood cells, especially WBCs and platelets, play an important role in this activation process. Neutrophils and monocytes are subpopulations of WBCs that increase the thrombotic potential by different mechanisms. Neutrophils are activated by tumor cells and can release DNA, generating highly thrombogenic neutrophil extracellular traps...

Multiple therapeutic agonists of death receptor 5 (DR5) have been developed and are under clinical evaluation. Although these agonists demonstrate significant anti-tumor activity in preclinical models, the clinical efficacy in human cancer patients has been notably disappointing. One possible explanation might be that the current classes of therapeutic molecules are not sufficiently potent to elicit significant response in patients, particularly for dimeric antibody agonists that require secondary cross-linking via Fcγ receptors expressed on immune cells to achieve optimal clustering of DR5...
