Venous thromboembolic disease (VTE) is a frequent complication in patients diagnosed with cancer and a cause of morbidity and mortality. Approximately 20% of thromboembolic episodes develop in association with active cancer. On the other hand, it is estimated that about 2-12% of cases, the thromboembolic episode is the first manifestation of an occult cancer, diagnosed at that time or subsequently, which offers an opportunity for early diagnosis and treatment. There are multiple factors that contribute to increase the risk of VTE in oncological patients in relation to specific characteristics of the patient, the tumor and the treatments. Knowledge of these risk factors will contribute to early diagnosis when signs of VTE appear, as well as the assessment of thromboprophylaxis if indicated. The diagnosis of VTE in patients with cancer does not differ of those who do not suffer from it. Regarding the treatment of VTE in these patients, low molecular weight heparin (LMWH), direct acting anticoagulants (DACs) and antivitamin K (VKA) are the most commonly used, although the dosing regimen and length are not clear yet. The management of these patients should be interdisciplinary and early, so the primary care physician plays a key role in this process as he/she is liaise with his/her patients. It is also necessary to update knowledge in order to improve the care of these patients. For these reasons, this document has been prepared by the Working Group on Vasculopathies of the Spanish Society of Primary Care Physicians (SEMERGEN) whose objective is to present the available information regarding the management of VTE that may appear in oncological patients, as well as the assessment of thromboprophylaxis and treatment, if appropriate, from an approach focused on a primary care field.
