Abstract

Children with cancer have an increased risk for venous thromboembolic events (VTEs) compared to the healthy pediatric population. VTE rates in children with cancer vary among cancer types. Other VTE risk factors include central venous catheters and cancer therapies. VTE diagnosis relies on objective radiological imaging, and management to this date typically involves anticoagulant therapy. Low-molecular-weight heparins (LMWHs) are the most common choice. Evidence for primary VTE prevention is conflicting, and antithrombin replacement, LMWH, or apixaban have been studied. Recently, direct oral anticoagulants such as rivaroxaban or dabigatran were investigated for VTE treatment, showing promise in efficacy and safety. However, bleeding risks in this population need careful consideration, especially periprocedurally or with treatment-related thrombocytopenia. Prediction tools for VTE require adaptation for pediatric cancer patients. Progress in understanding and managing VTE in children with cancer is significant, with ongoing trials and real-world data contributing to improved strategies.

Zusammenfassung

Kinder mit malignen Erkrankungen haben im Vergleich zu gesunden Kindern ein erhöhtes Risiko für venöse thromboembolische Ereignisse (VTE). Die VTE-Raten variieren je nach Krebsart. Weitere VTE-Risikofaktoren sind zentrale Venenkatheter und Chemotherapien. Die VTE-Diagnose beruht auf einer objektiven radiologischen Bildgebung, und die Behandlung umfasst in der Regel eine Antikoagulation. Niedermolekulare Heparine (LMWH) sind die häufigste Wahl. Studienergebnisse zur VTE-Prävention sind widersprüchlich. Es wurden bisher Antithrombin-Substitutionen, LMWH oder zuletzt Apixaban untersucht. In jüngster Zeit wurden direkte orale Antikoagulanzien (DOAC) wie Rivaroxaban oder Dabigatran für die VTE-Behandlung untersucht, die vielversprechend in Bezug auf Wirksamkeit und Sicherheit sind. Blutungsrisiken in dieser Patientengruppe müssen jedoch sorgfältig bedacht werden, insbesondere peri-interventionell oder bei behandlungsbedingter Thrombozytopenie. Die Fortschritte für das Verständnis und für die Behandlung von VTE bei Kindern mit malignen Erkrankungen sind beträchtlich, wobei laufende Studien zu verbesserten Strategien beitragen.
