Survival benefit of hepatic resection versus transarterial chemoembolization for hepatocellular carcinoma with portal vein tumor thrombus: a systematic review and meta-analysis.

No consensus treatment has been reached for hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). Hepatic resection (HR) and transarterial chemoembolization (TACE) have been recommended as effective options, but which is better remains unclear. This meta-analysis is to compare the effectiveness of HR and TACE for HCC with PVTT patients.
