OBJECTIVE: To evaluate the potential and efficacy of hepatic artery infusion chemotherapy combined with the PD-1/CTLA-4 bispecific antibody cadonilimab and the multi-kinase inhibitor donafenib in conversion therapy for unresectable hepatocellular carcinoma (uHCC) with Vp4-type portal vein tumor thrombus(PVTT).
METHODS: We present a case report of a 41-year-old male diagnosed with diffuse hepatocellular carcinoma (HCC) in the right lobe of the liver and tumor thrombus involving the main portal vein. Following multidisciplinary team evaluation, the patient received conversion therapy consisting of hepatic artery infusion chemotherapy (HAIC) using oxaliplatin, fluorouracil, and leucovorin, in combination with cadonilimab and donafenib.
RESULTS: Post-treatment imaging demonstrated marked regression of intrahepatic tumors and complete resolution of the portal vein tumor thrombus. Serum alpha-fetoprotein (AFP) levels normalized, and protein induced by vitamin K absence or antagonist-II (PIVKA-II) levels showed a significant decline. Subsequently, a radical right hepatectomy was successfully performed, and postoperative pathological examination confirmed complete response. The patient experienced an uneventful recovery and remained free of tumor recurrence during the one-year follow-up period.
CONCLUSION: The integrative treatment strategy combining HAIC with cadonilimab and donafenib demonstrates considerable promise as a conversion approach for patients with traditionally unresectable HCC with Vp4-type PVTT. This regimen may substantially improve oncological outcomes and enable curative resection. This case provides compelling evidence to support further clinical investigation of this multimodal therapeutic combination.
