Purpose
To examine national trends in the adoption and use of the LI-RADS Treatment Response Algorithm.
Methods
Members of the Society of Abdominal Radiology (SAR) Disease-Focused Panel (DFP) on LI-RADS Treatment Response (LR-TR) of hepatocellular carcinoma (HCC) developed a 15-question survey which was distributed to radiologists at academic and private practice institutions around the USA and Canada. The survey focused on HCC-related practice patterns as well as the adoption and use of the LR-TR algorithm.
Results
Of 122 surveys distributed, a total of 76 radiologists responded (62%). Responders were predominantly from academic centers (85%). Nearly all (96%) participate in multidisciplinary hepatic tumor boards and most (67%) have an active liver transplant program. All responders’ institutions perform locoregional therapy for HCC, including radiation-based therapy (TARE and SBRT). There was a preference for use of MRI over CT for follow-up after locoregional therapy. All responders were aware of the LR-TR algorithm and nearly all (92%) used the system in routine practice. Radiologists expressed a need for more visual aids related to the LR-TR system. Multiple respondents requested additional clarity within the LR-TR algorithm regarding the evolution of post-treatment radiation changes over time.
Conclusion
Most survey participants use the LR-TR algorithm after locoregional therapy for HCC. Future iterations of the algorithm may benefit from increased clarity regarding response after radiation-based therapies. Educational materials should include more visual aids to improve reader understanding.
