Abstract
IMPORTANCE: Transarterial chemoembolization (TACE) has been associated with a wide range of practice variations for hepatocellular carcinoma (HCC) between the East and the West. This considerable ambiguity may lead to the heterogeneous quality in treatment and have a negative impact on the role of TACE in the overall multidisciplinary HCC treatment system. OBJECTIVE: It may be a good start to establish a guideline worldwide to have this consensus from experts who represent east and west, although it does not cover all aspects of TACE. EVIDENCE REVIEW: An international expert panel on TACE is convened to cluster the expert's opinions and summary a standard consensus. This panel committee consist of leading physicians in TACE on HCC from USA, France, Japan, Singapore, Korea, China, and so on. The first-round face-to-face consensus meeting was held during in Nanjing, China in October 2019. The second-round conference for revision of the consensus was held during the Annual Meeting of Chinese College of Interventionalists in August 2020 by a hybrid format of a Webinar and roundtable meeting. After several on-line revisions, the final manuscript was approved by all members of the panel in June 2021. FINDINGS: The consensus statements were organized into the following categories: patients' selection, performing the procedure, TACE outcomes, repeat TACE, TACE failure/refractory, and TACE-based combination treatments. CONCLUSIONS AND RELEVANCE FOR REVIEWS: More and more evidences have showed the better outcomes with strategy of combined TACE with other local therapies such as ablations. The most-recently developing strategy of combined TACE with PD-1/PD-L1 plus tyrosine kinase inhibitor (TKI) agents has shined a light to the HCC patients, especially to those with high risk of tumor recurrence after treatment or TACE failure/refractory.
