摘要

Background

Periinterventional imaging of patients with hepatocellular carcinoma (HCC) during local and locoregional therapies plays a crucial role in clinical outcome by guiding treatment allocation, planning, and application. However, there is a considerable variety in clinical routine in terms of timing, modality, and imaging protocols. This study aimed to guide the standardization of the imaging procedures for patients with HCC by conducting a Delphi consensus-finding survey.

Methods

A multidisciplinary, multinational survey was conducted to standardize the imaging of patients with HCC using the Delphi method.

Results

Under the guidance of the European Organisation for Research and Treatment of Cancer (EORTC) Imaging and Gastrointestinal Tract Cancer Groups and the European Society of Gastrointestinal and Abdominal Radiology (ESGAR), the recommendations for imaging before, during, and after thermal ablation, transarterial chemoembolization, radioembolization, and stereotactic body radiation therapy were established.

Conclusion

This consensus protocol provides a foundational guide for imaging in the daily clinical management of HCC patients, as well as for prospective studies assessing local and locoregional therapies.

Key Points

Question There are clear recommendations for the respective therapies/disease stages in HCC, but only to a limited extent for all-around imaging of local therapies.

Findings This study conveyed a Delphi consensus-finding survey amongst European experts from multiple medical fields to standardize the periinterventional imaging of HCC patients.

Clinical relevance These recommendations can guide both daily clinical practice and prospective trials focused on local and locoregional therapies.
