Apixaban in low-weight patients with cancer-associated thrombosis: A cross sectional study of drug levels.

Introduction: Apixaban, a direct factor Xa inhibitor, has been shown to be at least as safe and probably more effective than dalteparin for the treatment of cancer-associated thrombosis (CAT) as reported in the ADAM-VTE and Caravaggio studies, which included a low percentage of underweight patients. Lower-weight-based dosing is supported by cancer-specific studies such as half-dose edoxaban in the Hokusai-VTE cancer trial in individuals weighing <60 kg.

Objective: To examine apixaban plasma trough levels in low-weight individuals with CAT, stably anticoagulated with full or half-dose apixaban.

[National guidelines of diagnosis and treatment of the non-Hodgkin lymphoma].

Non-Hodgkin lymphoma comprises a heterogeneous group of haematological malignancies, classified according to their clinic, anatomic-pathological features and, lately, to their molecular biomarkers. Despite the therapeutic advances, nearly half of the patients will die because of this disease. The new diagnostic tools have been the cornerstone to design recent therapy targets, which must be included in the current treatment guidelines of this sort of neoplasms by means of clinical trials and evidence-based medicine.

[Treatment of cancer and thrombosis: practical approach].

Individuals with cancer are at increased risk of developing thrombosis. The prevalence of thrombosis depends on tumor-related factors such as histological type, stage, the use of central venous catheters, or treatment with surgery, chemotherapy or radiotherapy, as well as general prothrombotic factors including advanced age, immobility, obesity, hereditary thrombophilias and comorbidities. Prophylactic or therapeutic treatment of thrombosis should be individualized and will depend on both the risk of thrombosis and bleeding.
