Non-surgical management of advanced hepatocellular carcinoma: A systematic review by Cancer Care Ontario

Abstract

BACKGROUND: Hepatocellular carcinoma (HCC) is a global health problem, accounting for 4.7% of all new cancer cases and 8.2% of all cancer deaths worldwide in 2018. Resection and transplantation are the only modalities that offer a cure for HCC; however, most patients are diagnosed at an advanced stage, precluding these curative treatments. A number of local (ie, ablative therapies) and/or local-regional therapies (ie, chemo-embolization) are used and followed by systemic therapy for advanced or progressive disease. Other treatments are available, but their efficacy compared with these standards is not well known. METHODS: Literature searches (1/2000 to 1/2020 or 1/2005 to 1/2020, depending on the specific systematic review question) were conducted, including MEDLINE, Embase and the Cochrane Database of Systematic Reviews. RESULTS: Over 30,000 articles were identified. In total, 49 studies were included in the systematic review. CONCLUSIONS: There is no evidence to support the addition of sorafenib to any local or regional therapy. First-line systemic therapy options for unresectable or metastatic HCC include sorafenib, lenvatinib, and atezolizumab + bevacizumab. Regorafenib or cabozantinib provide survival benefits when given as second-line treatment.
