Research progress on the formation mechanism of hepatocellular carcinoma with portal vein tumor thrombus / 中华肝胆外科杂志

ABSTRACT

Hepatocellular carcinoma is a common malignant disease in clinical practice, and portal vein tumor thrombosis (PVTT) is one of the important factors affecting the prognosis of hepatocellular carcinoma. PVTT has strong oncologic characteristics and is highly susceptible to extrahepatic metastasis, complicating portal hypertension, leading to gastrointestinal bleeding or liver failure and causing death. In this paper, we review the formation mechanism of hepatocellular carcinoma combined with PVTT in terms of local anatomy, hemodynamics, molecular biology and tumor microenvironment to provide effective reference for clinical treatment.
