Glossary This glossary defines terms as they are used in reports produced by the Drug Effectiveness Review Project. Some definitions may vary slightly from other published definitions. Absolute risk: The probability or chance that a person will have a medical event. It is the ratio of the number of people who have a medical event divided by all of the people who could have the event because of their medical condition. Add-on therapy: An additional treatment used in conjunction with the primary or initial treatment. Adherence: Following the course of treatment proscribed by a study protocol. Adverse drug reaction: An adverse effect specifically associated with a drug. Adverse event: A harmful or undesirable outcome that occurs during or after the use of a drug or intervention but is not necessarily caused by it. Adverse effect: An adverse event for which the causal relation between the intervention and the event is at least a reasonable possibility. Active-control trial: A trial comparing a drug in a particular class or group with a drug outside of that class or group. Allocation concealment: The process by which the person determining randomization is blinded to a study participant’s group allocation. Applicability: see External Validity Before-after study: A type nonrandomized study where data are collected before and after patients receive an intervention. Before-after studies can have a single arm or can include a control group. Bias: A systematic error or deviation in results or inferences from the truth. Several types of bias can appear in published trials, including selection bias, performance bias, detection bias, and reporting bias. Bioequivalence: Drug products that contain the same compound in the same amount that meet current official standards, that, when administered to the same person in the same dosage regimen result in equivalent concentrations of drug in blood and tissue. Black box warning: A type of warning that appears on the package insert for prescription drugs that may cause serious adverse effects. It is so named for the black border that usually surrounds the text of the warning. A black box warning means that medical studies indicate that the drug carries a significant risk of serious or even life-threatening adverse effects. The US Food and Drug Administration (FDA) can require a pharmaceutical company to place a black box warning on the labeling of a prescription drug, or in literature describing it. Blinding: A way of making sure that the people involved in a research study — participants, clinicians, or researchers —do not know which participants are assigned to each study group. Blinding usually is used in research studies that compare two or more types of treatment for an illness. Disease-modifying drugs for multiple sclerosis Page 98 of 120 Final Report Update 1 Drug Effectiveness Review Project Case series: A study reporting observations on a series of patients receiving the same intervention with no control group.

Neutrophils are activated by tumor cells and can release DNA generic cialis super active 20 mg, generating highly thrombogenic neutrophil extracellular traps generic cialis super active 20mg mastercard. Monocytes are able to synthesize and express significant quantities of procoagulant tissue factor on their surfaces upon activation. An increased risk of VTE has been found in patients with solid tumors and elevated platelet count and in those with high-grade gliomas and low platelet count. Small circulating membrane vesicles, also called microparticles (MPs), which largely derive from platelets, contribute to the procoagulant potential. Specifically, procoagulant MPs could play a role in tumor-associated thrombosis in pancreatic cancer. Interventional studies are under way that are investigating the benefits of thromboprophylaxis in patients identified to be at high risk of VTE through risk-scoring models that include blood count parameters. The “flames” thrown by blood cells, such as neutrophil extracellular traps and MPs, although exciting, still have to be investigated for their usefulness in the clinical setting. All Learning Objectives blood cells, but primarily platelets, can produce small vesicles, ● To understand that blood cells play an important role in so-called microparticles (MPs), upon activation or during apoptosis cancer-associated VTE that exert procoagulant activity. WBCs have been described to ● To understand that altered parameters of blood cell count have produce neutrophil extracellular traps (NETs) that might promote been reported to be associated with incident VTE; however, the activation of the clotting system and lead to VTE. This is particularly the case in patients with Cancer is an important risk factor for venous thrombosis and pulmo- lung cancer. Interestingly, Thomson et al could show that the nary embolism, commonly known as venous thromboembolism (VTE). Khorana et al first described an associa- to increase the risk of VTE. The probability of developing VTE varies tion between an elevated WBC count and an increased risk of VTE considerably among cancer patients depending on the tumor type, 34 1 (Table 1).

For this review, we performed elevated, but not high enough to justify mandatory thromboprophylaxis 2-4 an evaluation of blood cell parameters’ association with the risk of in each cancer patient. In recent years, research has focused on predictive parameters to identify patients at low or high risk of VTE VTE in the framework of the Vienna Cancer and Thrombosis Study during the course of their disease. Patients with a low risk would not be (CATS), a prospective observational cohort study that includes patients with various cancer entities. Patients at high risk would most probably that was used in a recent publication by Ko¨nigsbru¨gge et al, but only included patients with solid tumors. An increase of 1 G/L in the WBC was associated with a 7% increase in the risk of Blood cells (WBCs, RBCs, and platelets) are known to be altered in VTE [risk ratio (RR) 1.

Importantly, NETs have been shown to be highly promoting coagulation via the extrinsic pathway.
