Heghine Khachatryan: Real-World Data on DOAC Use in Pediatric Oncology
Heghine Khachatryan, Editor-in-Chief of Hemostasis Today, Head of Hemophilia and Thrombosis Center at Yeolyan Hematology and Oncology Center, shared RPTH’s post on LinkedIn:
“New evidence continues to refine our understanding of anticoagulation in complex pediatric populations.
A recent publication in Research and Practice in Thrombosis and Haemostasis (RPTH) explores the safety and efficacy of direct oral anticoagulants (DOACs) in pediatric oncology patients, presenting real-world data from two tertiary pediatric centers.
Children with cancer represent a particularly vulnerable group, where thrombosis risk is increased due to malignancy, central venous catheters, and treatment-related factors.
Determining the optimal balance between thrombosis prevention and bleeding risk remains a critical clinical challenge.
Real-world data such as these are essential for guiding evidence-based decisions and improving outcomes in pediatric cancer-associated thrombosis.
Continued research will help clarify the role of DOACs in this delicate patient population.”
RPTH Journal shared a post on LinkedIn about a recent article by Riten Kumar et al, adding:
“Are DOACs truly safe for children with cancer-associated thrombosis?
Direct oral anticoagulants are transforming anticoagulation in adults.
But in pediatric oncology, the evidence base is still evolving.
A new real-world RPTH study examined 51 children with cancer receiving DOACs for treatment or prevention of VTE across two major pediatric centers.
Here’s the key signal:
- Recurrent or progressive thrombosis occurred in 8% of patients
- Major bleeding occurred in 6%, and clinically relevant nonmajor bleeding in 20%.
What’s important about these findings
- Most patients received rivaroxaban or apixaban
- Nearly half achieved complete thrombus resolution on follow-up imaging
- Bleeding events were often linked to chemotherapy-related thrombocytopenia
- Real-world complication rates were higher than some clinical trials
Translation:
DOACs are promising in pediatric oncology but real-world complexity matters.
Big questions moving forward:
- What is the optimal anticoagulation intensity in children with cancer?
- How should platelet thresholds guide anticoagulation decisions?
- Can we better balance thrombosis prevention with bleeding risk during chemotherapy?”
