AbstractAims/Background: 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. Case Presentation: Two cases of HCC with PVTT were presented. Patient 1, a 51-year-old male with a history of hepatitis B virus, was diagnosed with stage IIIA HCC and treated with camrelizumab + apatinib, achieving complete response (CR) after six cycles. Patient 2, a 50-year-old male with stage IIIA HCC, also underwent the same treatment and achieved CR after four cycles but died due to acute cardiac disease. Results: Our research found that camrelizumab + apatinib effectively shrank the size of filling defects and significantly prolonged patients' progression-free survival. In addition, no adverse effects were observed during the treatment process. However, despite the manageable safety profile demonstrated by combination therapy, further clinical research is needed to validate its long-term efficacy and safety. Conclusion: Camrelizumab + apatinib produced satisfactory efficacy and safety among the HCC patients with PVTT, providing clinical evidence for future treatment.
