Should health policy prioritize specialists who offer lower-cost interventional cancer treatments?
Interventional radiologists treated 51% of Medicare patients with liver cancer between 2016 and 2021. This retrospective analysis evaluated care patterns for approximately 110,000 patients annually.
Why it matters
Understanding which specialists handle different aspects of care helps patients navigate the multidisciplinary teams often required for complex liver cancer management. These findings highlight the integration of interventional radiology into the standard oncology care path.
A retrospective study of Medicare claims from 2016 to 2021 tracked 110,000 patients per year to determine provider utilization. Researchers found interventional radiologists managed 51% of cases, though the impact on clinical outcomes remains unknown.
The players
Medicare
The federal health insurance program that provides coverage for individuals aged 65 and older and those with certain disabilities.
The details
Interventional radiologists provide care through minimally invasive, image-guided procedures. Their work includes biopsies, venous access, and drainage, as well as specialized tumor treatments like percutaneous ablation, transarterial chemoembolization, and radioembolization. These procedures allow for targeted local control of liver tumors using catheters or needles guided by real-time imaging technology.

Health Landscape
This analysis reflects the evolving landscape of multidisciplinary oncology, where interventional procedures are increasingly central to care delivery. It sits against the backdrop of the CMS Medicare Physician Fee Schedule, which tracks these shifting patterns in how specialists are compensated.
If you are managing a liver cancer diagnosis, your care team may include various specialists, making it helpful to ask which specific procedures your interventional radiologist will perform. Discussing your full treatment plan with your oncologist ensures you understand how these image-guided therapies fit into your overall health strategy.
The takeaway
Interventional radiologists provide a significant portion of liver cancer care, utilizing image-guided techniques that are distinct from those used by medical or radiation oncologists. When coordinating your care, confirm with your physician which specialists will be performing any planned diagnostic or interventional procedures.
