Camrelizumab Combined with Apatinib for Portal Vein Tumor Thrombus in Advanced Hepatocellular Carcinoma: Two Case Reports

Portal vein tumor thrombus (PVTT) is a common complication of primary hepatocellular carcinoma (HCC). HCC typically infiltrates intrahepatic vessels, particularly the portal vein, leading to the formation of PVTT, marking advanced-stage HCC and correlating with poor prognosis. PVTT often complicates local treatment strategies such as surgical resection and affects the efficacy of interventions. Combination therapy, including immunotherapy and targeted therapy, shows promise in HCC treatment, but management options for HCC patients with PVTT are incompletely characterized. This study aims to investigate the efficacy and safety of camrelizumab + apatinib in treating HCC patients with PVTT.
