BACKGROUND: Children with acute lymphoblastic leukemia (ALL) have increased risk of thromboembolism (TE). However, the predictors of ALL-associated TE are as yet uncertain. OBJECTIVE: This exploratory, prospective cohort study evaluated the effects of clinical (age, gender, ALL risk group) and laboratory variables (hematological parameters, ABO blood group, inherited and acquired prothrombotic defects [PDs]) at diagnosis on the development of symptomatic TE (sTE) in children (aged 1 to ≤18) treated on the Dana-Farber Cancer Institute ALL 05-001 study...

The survival rate of children with cancer is now close to 80 %, as a result of continuous improvement in diagnostic and treatment procedures. Prevention and treatment of treatment-associated complications is now a major challenge. Thromboembolic venous disease, due to multifactorial pathogenesis, is a frequent complication (up to 40 % asymptomatic thrombosis in children with cancer), responsible for significant morbidity. Predominantly in children with acute lymphoblastic leukemia, lymphoma, or sarcoma, thromboembolic disease justifies primary prophylaxis in certain populations at risk, whether genetic or environmental...

BACKGROUND: Neutrophil extracellular traps (NETs) are decondensed chromatin fibers which might play a role in the prothrombotic state of cancer patients. OBJECTIVES: Here we investigated whether citrullinated histone H3 (H3Cit), a biomarker for NET formation, cell-free DNA (cfDNA), and nucleosomes predict venous thromboembolism (VTE) in cancer patients. PATIENTS/METHODS: Nine-hundred-forty-six patients with newly-diagnosed cancer or progression after remission were enrolled in this prospective observational cohort study...

Few prospective studies have examined the factor V paradox: factor V Leiden (FVL) is a stronger risk factor for deep venous thrombosis (DVT) than for pulmonary embolism (PE). The present study, to the best of our knowledge, is the first population-based study aimed to examine the relationship between FVL and incidence of venous thromboembolism (VTE), DVT and PE in a prospective cohort study of middle-aged Swedish individuals. FVL was determined in 4890 subjects (aged 46-68 years, 57% women) from the general population without previous VTE or cancer, who participated in the Malmö Diet and Cancer study between 1991 and 1994...

Fibrinogen is a unique protein that is converted into an insoluble fibrin in a single enzymatic event, which is a characteristic feature of fibrinogen due to its susceptibility to fibrinolytic degradation and dissolution. Although thrombosis is a result of activated blood coagulation, no explanation is being offered for the persistent presence of fibrin deposits in the affected organs. A classic example is stroke, in which the thrombolytic therapy is effective only during the first 3-4 h after the onset of thrombosis...

A 69-year-old woman with focal infrarenal aortic stenosis was diagnosed with rectosigmoid cancer. Because radical resection for colon cancer required dissection of vessels that supplied blood flow to the legs, revascularization by aortic stent placement was performed before the colectomy. We subsequently performed laparoscopic low anterior resection without any complications. Two and a half years after colectomy, however, the patient developed colonic ischemia due to thrombosis of the dilated marginal artery that served as a collateral artery before stenting...

BACKGROUND: Non-hip non-vertebral fractures (NHNV) constitute the majority of osteoporotic fractures but few studies have examined the association between these fractures, co-morbidity and mortality. OBJECTIVE: To examine the relationship between individual non-hip non-vertebral fractures, co-morbidities and mortality. METHODS: Prospective population-based cohort of 267,043 subjects (45 and Up Study, Australia) had baseline questionnaires linked to hospital administrative and all-cause mortality data from 2006 - 2013...

Melanoma is known as the most common malignant cutaneous cancer. Curcumin, a natural component, has been shown to have various activities such as anti-oxidant, anti-septic, anti-inflammatory, anti-biotic, anti-amyloid and anti-thrombosis. However, there is a greatest obstacle in the administration of curcumin due to its hydrophobicity and low oral bioavailability. In this study, we formulated curcumin-loaded MPEG-PLA (Curcumin/MPEG-PLA) micelles aiming to improve its solubility in aqueous solution and investigated anti-tumor effect on melanoma in vitro and in vivo...

During vascular development, endothelial cells (ECs) and neighboring stromal cells interact and communicate through autocrine and paracrine signaling mechanisms involving extracellular matrix (ECM) proteins and their cell surface integrin adhesion receptors. Integrin-mediated adhesion and signaling pathways are crucial for normal vascular development and physiology, and alterations in integrin expression and/or function drive several vascular-related pathologies including thrombosis, autoimmune disorders, and cancer...

BACKGROUND: Thromboembolic events (TEEs) represent a significant treatment and disease complication for cancer patients. In the present study we assessed the incidence of TEEs in patients receiving preoperative chemotherapy for esophagogastric adenocarcinoma. The risk factors for TEE development and their impact on prognosis were further analyzed. MATERIAL AND METHODS: Data from 590 patients with esophagogastric adenocarcinoma, who received preoperative epirubicin-cisplatin with capecitabine (ECX) or 5-fluorouracil (ECF) between 2009 and 2016 in three UK hospitals were retrospectively collected...

BACKGROUND: Little is known about predictors and outcomes of recurrent venous thromboembolism in elderly patients. METHODS: We prospectively followed up 991 patients aged ≥65 years with acute venous thromboembolism in a multicenter Swiss cohort study. The primary outcome was symptomatic recurrent venous thromboembolism. We explored the association between baseline characteristics and treatments and recurrent venous thromboembolism using competing risk regression, adjusting for periods of anticoagulation as a time-varying co-variate...

Evidence-based clinical practice guidelines are available to provide guidance to clinicians in managing patients living with cancer-associated venous thromboembolism (VTE). While most are developed using rigorous methods and grounded by systematic reviews of the literature, their recommendations do differ because of differences in their grading criteria and interpretation of the data. This can be confusing to practicing clinicians. Also, guidelines are often out of date and cannot keep pace with publications because of the lengthy processes and extensive resources required for completion...

Cancer patients have an increased risk of venous thromboembolism (VTE) compared with the general population. Mouse models are used to better understand the mechanisms of cancer-associated thrombosis. Several mouse models of cancer-associated thrombosis have been developed that use different mouse strains, tumors, tumor sites and thrombosis models. In this review, we summarize these different models. These models have been used to determine the role of different pathways in cancer-associated thrombosis. For instance, they have revealed roles for tumor-derived tissue factor-positive microvesicles and neutrophil extracellular traps in thrombosis in tumor-bearing mice...

Neutrophil pathogen-killing mechanism termed neutrophil extracellular traps (NETs) has been recently identified. NETs consist of chromatin and histones along with serine proteases and myeloperoxidase and are induced by a great variety of infectious and non-infectious stimuli. NETosis is a kind of programmed neutrophil death characterized by chromatin decondensation and release of nuclear granular contents, mainly driven by peptidylarginine deiminase 4 citrullination of histones. Although classically related to the protection against infectious pathogens, nowadays NETs have been described as a player of several pathophysiological processes...

The relation between cancer and thrombosis is well known. In fact, the presence of an occult malignancy in patients with unprovoked venous thromboembolism (VTE) is named after a famous 19th century French physician; it is called Trousseau's sign. In this commentary, I elaborate upon findings from a recent individual patient data meta-analysis on Trousseau's sign. This study demonstrated that extensive screening to unmask an occult malignancy in unprovoked VTE is no better than 'simple' history taking and physical examination, alongside age-specific and gender-specific national cancer screening e...

The plasma levels of pro- and anticoagulant proteins are important markers for venous thrombosis (VT) risk and can be affected by both genetic and acquired factors, including cancer. Generally, these markers are measured using activity- or antibody-based assays. Targeted proteomics with stable-isotope-labeled internal standards has proven adept at the rapid, multiplex, and precise quantification of proteins in complex biological samples such as plasma. We used liquid chromatography coupled to multiple reaction monitoring (MRM) mass spectrometry to evaluate the concentrations of 31 coagulation- and fibrinolysis-related proteins in plasma from 25 healthy controls, 25 patients with VT, and 25 patients with VT who were also diagnosed with cancer...

BACKGROUND: Oral anticoagulants may improve the survival of people with cancer through both an antitumor effect and antithrombotic effect, yet increase the risk of bleeding. OBJECTIVES: To evaluate the efficacy and safety of oral anticoagulants in ambulatory people with cancer undergoing chemotherapy, hormonal therapy, immunotherapy or radiotherapy, but otherwise have no standard therapeutic or prophylactic indication for anticoagulation. SEARCH METHODS: We conducted a comprehensive literature search in February 2016 that included a major electronic search of Cochrane Central Register of Controlled Trials (CENTRAL) (2016, Issue 1), MEDLINE (Ovid) and Embase (Ovid); handsearching of conference proceedings; checking of references of included studies; a search for ongoing studies; and using the 'related citation' feature in PubMed...

Portal vein tumor thrombosis (PVTT) with advanced gastric cancer is very rare; when it occurs, it exhibits aggressive growth and carries a poor prognosis. In addition, definitive treatment has not been established due to insufficient data. Herein, we report a case of PVTT associated with an adenocarcinoma of the esophagogastric junction that was successfully controlled by means of a palliative total gastrectomy without surgical resection of the PVTT and administration of palliative continuous doxifluridine.

BACKGROUND: Deep venous thrombosis (DVT) is associated with severe morbidity and mortality in cancer. Mean platelet volume (MPV) is an indicator of activated platelets. OBJECTIVE: We aimed to investigate whether the combination of D-dimer and MPV could have a better performance in predicting deep venous thrombosis (DVT) in patients with breast cancer. MEHTODS: In 342 consecutive breast cancer patients without preoperative DVT, we measured the preoperative D-dimer and MPV levels...
