Abstract
Cabozantinib is a multi-kinase inhibitor targeting multiple tyrosine kinases. It improves overall survival and progression-free survival in patients previously treated with sorafenib for advanced hepatocellular carcinoma (HCC) compared to the placebo in the phase 3 CELESTIAL trial. A 71-year-old man presented to our hospital for treatment of HCC with chronic hepatitis C. He was refractory to sorafenib, lenvatinib, regorafenib, and ramucirumab and started atezolizumab and bevacizumab therapy in November 2020. After administering the second cycle on December 10, 2020, the patient was diagnosed with progressive disease in January 2021. Therefore, cabozantinib (60 mg/day) was initiated on January 14, 2021. As the grade 3 aspartate aminotransferase and alanine aminotransferase levels increased, grade 3 anorexia and a decline in performance status were observed in the first week, and cabozantinib was terminated. His performance status and anorexia gradually improved, and contrast-enhanced computed tomography (CT) in June 2021 showed complete remission (CR) according to the modified Response Evaluation Criteria in Solid Tumors. The patient did not show disease progression for 11 months without receiving any treatment for HCC. To the best of our knowledge, this is the first report of CR with cabozantinib in advanced HCC.
