Association of smoking and cancer with the risk of venous thromboembolism: the Scandinavian Thrombosis and Cancer cohort.

Smoking is a well-established risk factor for cancer, and cancer patients have a high risk of venous thromboembolism (VTE). Conflicting results have been reported on the association between smoking and risk of VTE, and the effect of smoking on VTE-risk in subjects with cancer is scarcely studied. We aimed to investigate the association between smoking and VTE in subjects with and without cancer in a large population-based cohort.

Combined effects of five prothrombotic genotypes and cancer on the risk of a first venous thromboembolic event.

Background: The role of combined prothrombotic genotypes in cancer-related venous thromboembolism (VTE) is scarcely studied. We aimed to investigate the impact of a 5-single nucleotide polymorphism (SNP) score on the risk of VTE in patients with and without cancer using a population-based case-cohort.

Methods: Cases with a first VTE (n = 1493) and a subcohort (n = 13 072) were derived from the Tromsø Study (1994-2012) and the Nord-Trøndelag Health Study (1995-2008).

Fibrinogen gamma gene and risk of cancer-related venous thromboembolism.

Venous thromboembolism (VTE) is a frequent complication in patients with cancer. Homozygous carriers of the fibrinogen gamma gene have a moderately increased risk of VTE, but the effect of the variant in cancer is unknown. We aimed to investigate the effect of the variant and active cancer on the risk of VTE.

Prothrombotic genotypes and risk of venous thromboembolism in cancer.

Venous thromboembolism (VTE) is a common and potentially life-threatening complication in cancer. Patients with cancer are at a higher risk of VTE-related complications such as major bleeding during anticoagulant treatment, recurrence and mortality. Therefore, it is important to identify cancer patients with high risk of VTE in order to implement targeted prevention to those with a favorable benefit-to-harm ratio for thromboprophylaxis.

Long-Term Incidence of Venous Thromboembolism in Cancer: The Scandinavian Thrombosis and Cancer Cohort.

The risk of venous thromboembolism (VTE) in patients who survive the first years after a cancer diagnosis after the acute effects of disease and treatment in comparison to a similar background population has been sparsely investigated. The aim of the study was to investigate if incidence rates (IRs) of VTE differed in patients who were alive at least 2 years after a cancer diagnosis without VTE compared with cancer-free references in a population-based cohort study. The study entry was 2 years after a first cancer diagnosis.

Epidemiology of venous thromboembolism in hematological cancers: The Scandinavian Thrombosis and Cancer (STAC) cohort.

Introduction: Venous thromboembolism (VTE) is an important cause of morbidity and mortality in cancer patients, however the risk of VTE differs according to cancer type. Hematological cancers have varying phenotypes. Incidence rates (IR) of VTE in different hematological cancer types have not been investigated in a cancer-exposed subset of the general population.

Joint effects of cancer and variants in the factor 5 gene on the risk of venous thromboembolism.

Venous thromboembolism occurs frequently in cancer patients. Two variants in the factor 5 gene (F5), rs6025 encoding for the factor V Leiden mutation R506Q, and rs4524 encoding K858R, have been found to be associated with venous thromboembolism. We assessed the joint effect of active cancer and these two F5 variants on venous thromboembolism risk in a case-cohort study.
