Abstract
e16172 Background: In patients with advanced hepatocellular carcinoma (HCC) progressing after atezolizumab and bevacizumab, the optimal therapy scheme is debatable and the efficacy of regorafenib combined with PD-1 inhibitors is still unclear. Methods: In this retrospective study, advanced HCC patients who received regorafenib combined with PD-1 inhibitors progressing after atezolizumab plus bevacizumab were consecutively enrolled from February 2022 to January 2024. Main efficacy endpoint was overall survival (OS), following progression free survival (PFS), evaluated in accordance with RECIST v1.1. Adverse events (AEs) were recorded according to CTCAE v5.0. Results: A total of 11 eligible patients were enrolled, with 8 in Child-Pugh A and 3 in Child-Pugh B7. All patients had hepatitis B infection by with tumor embolus. All patients were classified as Barcelona Clinic Liver Cancer stage C. The AFP level is above 400ng/ml in all patients. At data cut-off at February 2024, the median OS was 16.9 months and the median PFS was 3.7 months. The 3-month and 6-month PFS rates were 70% and 35% , respectively. The 12-month OS rate was 71.4%. Grade≥3 TRAEs occurred in 9.1% (1/11) of the patients. Conclusions: Though application of regorafenib combined with PD-1 inhibitors progressing after atezolizumab plus bevacizumab present safe and effective in our cohort, these data need to be confirmed in prospective comparative studies.
