The use of transcatheter embolization in its various forms in interventional oncology
has altered the treatment paradigms for multiple types of cancer. Though direct investigation
of the immunologic effects of transcatheter treatments has been limited, research
on radiation therapy can be extrapolated to better understand the potential effects
of radioembolization and studies on the immune response to chemotherapy can potentially
explain the immune response to hepatic artery infusion and chemoembolization. Utilization
of newer systemic immunotherapies in combination with various transcatheter therapies
also presents the potential for improving outcomes for multiple malignancies. This
review will discuss the role of transcatheter therapies in stimulating an immune response
as well as the potential these techniques have to enhance the effects of systemic
immunotherapy.
