RESUMO

Cancer patients have an increased thrombotic risk of arterial and venous thrombosis. Thrombocytopenia, particularly with anticoagulation, exposes the patient to an increased risk of bleeding but does not reduce the risk of recurrent thrombosis. When platelets are < 50 × 109/l, the strategy regarding anticoagulation must be reassessed. Based on the thrombotic and bleeding risks as well as the expected duration of thrombocytopenia, management options include full-dose treatment with platelet transfusion, reduced-dose anticoagulation or withholding antithrombotic therapy. Aspirin treatment appears to be a reasonable choice for thrombocytopenic (> 30 × 109/l) patients with acute coronary syndrome. This paper will review the guidelines on anticoagulation and antiplatelet therapy in thrombocytopenic cancer patients.


Les patients avec un cancer ont un risque thrombotique artériel et veineux accru. En cas de thrombocytopénie et traitement anticoagulant (ou antiagrégant), ils sont exposés à un risque hémorragique augmenté mais conservent un risque thrombotique élevé. L'évaluation de l'anticoagulation s'impose pour des thrombocytes < 50 × 109/l. En fonction des risques thrombotique et hémorragique et de la durée de la thrombocytopénie, les options sont la poursuite de l'anticoagulation, le recours aux transfusions plaquettaires, la réduction de la dose ou son interruption. Un traitement par aspirine en cas de syndrome coronarien aigu est raisonnable pour des thrombocytes > 30 × 109/l. Cet article propose une revue des recommandations concernant les traitements anticoagulants ou antiagrégants en cas de thrombocytopénie chez les patients oncologiques.
