Mark the wrong answer regarding endovascular approaches in paediatric interventional oncology:

• Combined techniques, which use endovascular approaches for drug delivery with percutaneous tumour ablation techniques could potentially be applied in paediatric patients

• The lack of substantial evidence is one of the major drawbacks for wider acceptance of paediatric endovascular interventional oncological treatments

• In children typically, particle sizes 500–700μm are favored because smaller particles can cause biliary necrosis and bilomas and larger particles do not cause sufficient tumor ischemia (the correct size is 100-300)

• Bland embolization can be used, both for local control and symptom palliation, in bone tumors
