Although systemic therapies are a common treatment for patients with extrahepatic metastases, local ablative therapies for the extrahepatic metastatic lesions can be performed in selected patients. In this article, the literature on image-guided thermal ablation for metastasis to each organ was reviewed to summarize the current evidence. Radiofrequency ablation was the most commonly evaluated technique, and microwave ablation, cryoablation, and percutaneous ethanol injection were also utilized. The local control rate of thermal ablation therapy was relatively favorable, at approximately 70\u201390% in various organs. The survival outcomes varied among the studies, and several studies reported that the absence of viable intrahepatic lesions was associated with improved survival rates. Since only retrospective data from relatively small studies has been available thus far, more robust studies with prospective designs and larger cohorts are desired to prove the usefulness of thermal ablation for extrahepatic metastases from HCC.<\/jats:p>","DOI":"10.3390\/cancers15143665","type":"journal-article","created":{"date-parts":[[2023,7,19]],"date-time":"2023-07-19T00:54:01Z","timestamp":1689728041000},"page":"3665","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Image-Guided Ablation Therapies for Extrahepatic Metastases from Hepatocellular Carcinoma: A Review"],"prefix":"10.3390","volume":"15","author":[{"given":"Noriyuki","family":"Umakoshi","sequence":"first","affiliation":[{"name":"Department of Radiology, Okayama University Hospital, 2-5-1 Shikata-cho, Kitaku, Okayama 700-8558, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Matsui","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, 2-5-1 Shikata-cho, Kitaku, Okayama 700-8558, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koji","family":"Tomita","sequence":"additional","affiliation":[{"name":"Department of Radiology, Okayama University Hospital, 2-5-1 Shikata-cho, Kitaku, Okayama 700-8558, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mayu","family":"Uka","sequence":"additional","affiliation":[{"name":"Department of Radiology, Okayama University Hospital, 2-5-1 Shikata-cho, Kitaku, Okayama 700-8558, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takahiro","family":"Kawabata","sequence":"additional","affiliation":[{"name":"Department of Radiology, Okayama University Hospital, 2-5-1 Shikata-cho, Kitaku, Okayama 700-8558, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshihiro","family":"Iguchi","sequence":"additional","affiliation":[{"name":"Department of Radiological Technology, Okayama University Graduate School of Health Science, 2-5-1 Shikata-cho, Kitaku, Okayama 700-8558, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takao","family":"Hiraki","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, 2-5-1 Shikata-cho, Kitaku, Okayama 700-8558, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"284","DOI":"10.1016\/j.jhep.2018.10.008","article-title":"Hepatocellular carcinoma in the setting of alcohol-related liver disease","volume":"70","author":"Nahon","year":"2019","journal-title":"J.
