Clinical trials of interventional oncology—moving from efficacy to outcomes

Interventional oncology aims to develop new disease-modifying treatment options beyond conventional surgical and oncological therapies. Clinical investigators should incorporate measures of cost-effectiveness and patient-reported outcomes into large-scale studies to provide robust evidence for changing clinical practice. In particular, interventional oncology trials could be designed to show that certain treatments might be as effective as the current standard of care, but with less morbidity and better outcomes for patients with cancer.
