Abstract
Cabozantinib was found to be effective as a second- or third-line treatment after sorafenib in patients with advanced hepatocellular carcinoma (HCC) in the phase 3 CELESTIAL trial. So far, as immunotherapy has substituted molecular target agents as the primary systemic therapy for advanced HCC, cabozantinib is extensively used in the latest real-world clinical practice in a greatly different position than that shown by the CELESTIAL trial. In the current analysis, we examined the safety and effectiveness of cabozantinib administration in real-life settings for patients with advanced HCC. We retrospectively obtained data from patients with advanced HCC who received cabozantinib in three institutions in Japan between 14 September 2018 and 30 November 2021. During the study period, 23 patients with advanced HCC received cabozantinib. Our cohort included 21.7% of patients with Child-Pugh class B, and 52.2% of patients in fourth line or later. The median progression-free survival of patients given cabozantinib was 3.7months. Regarding patients with Child-Pugh class B or administration in fourth line or later, the discontinuation rate due to adverse events in patients who initialized at 40 or 20mg was lower than those who initialized at 60mg (42.9% versus 75.0%). Patients who were able to continue treatment with cabozantinib for more than 3months were more likely to undergo dose reduction than those who did not (85.7% versus 25.0%). Cabozantinib has recently been administered to a diverse range of patients, including those who were not enrolled in the CELESTIAL trial. Deliberate dose reduction could potentially offer clinical benefits to patients with impaired liver function. Furthermore, managing adverse events by reducing the dose could play a crucial role in extending the duration of treatment with cabozantinib.
