TACE Plus Bevacizumab for Hepatocellular Carcinoma With Portal Vein Invasion

The intervention consists of a combination treatment. Patients undergo transcatheter hepatic artery chemoembolization (TACE), a procedure involving localized delivery of chemotherapy and embolization of the tumor-feeding arteries. This is combined with a targeted arterial perfusion of bevacizumab, a monoclonal antibody that inhibits vascular endothelial growth factor (VEGF).

Patients in the control group received conventional therapy, which typically consists of TACE alone for this patient population. This involves the selective catheterization of hepatic arteries supplying the tumor, followed by the infusion of chemotherapeutic agents and an embolic agent to induce tumor necrosis.
