Hepatic vein tumor thrombosis in patients with hepatocellular carcinoma: Prevalence and clinical significance.

2021

Abstract Background There is strong evidence that portal vein tumor thrombosis (PVTT) is associated with poor survival in patients with hepatocellular carcinoma (HCC). However, data regarding the clinical significance of hepatic vein tumor thrombosis (HVTT) is rare, particularly in Western patients. Objective To determine the HVTT prevalence in a Western patient population and its impact on survival. Methods We included 1310 patients with HCC treated in our tertiary referral center between January 2005 and December 2016. HVTT and PVTT were diagnosed with contrast‐enhanced cross‐sectional imaging. Overall survival (OS) was calculated starting from the initial HCC diagnosis, and in a second s…
