Five-year complete remission of super-giant hepatocellular carcinoma with hepatectomy followed by sorafenib plus camrelizumab: A case report.

Background: Cirrhotic patients with super-giant hepatocellular carcinoma (HCC) and portal vein invasion generally have a poor prognosis. This paper presents a patient with super-giant HCC and portal vein invasion, who underwent hepatectomy followed by a combination of sorafenib and camrelizumab, resulting in complete remission (CR) for 5 years.

Case summary: A 40-year-old male with compensated hepatitis B-related cirrhosis was diagnosed with HCC, Barcelona Clinic Liver Cancer stage C. Enhanced computed tomography imaging revealed a 152 mm × 171 mm tumor in the right liver, invading the portal vein and hepatic vein. Liver function was normal. The patient successfully underwent hepatectomy on July 18, 2019. However, by December 2019, HCC recurrence with lung metastases and portal vein invasion were detected. He started treatment with sorafenib (200 mg twice daily) and camrelizumab (200 mg every 3 weeks). By May 12, 2020, the patient was confirmed to have CR. Camrelizumab was adjusted to 200 mg every 12 weeks from June 16, 2021, with the last infusion on March 29, 2024. Although no further tumor recurrence was observed, he experienced two episodes of gastrointestinal bleeding due to esophagogastric varices, which were managed with endoscopic therapy. To date, the patient has remained in CR for 5 years.

Conclusion: The combination of hepatectomy with sorafenib and camrelizumab can achieve durable CR in patients with super-giant HCC and portal vein invasion. Further research is necessary to address these challenges and improve patient outcomes.
