- Abstract
Summary: Background: Atezolizumab plus bevacizumab (Atezo/Bev) is frequently selected as the primary systemic therapy for hepatocellular carcinoma (HCC). Aims: To investigate the outcomes of patients with HCC treated with Atezo/Bev in a real‐world setting based on whether they met the inclusion criteria for the phase 3 IMbrave150 trial. Methods: A total of 936 patients were enrolled. There were 404 patients who met the inclusion criteria of the phase 3 IMbrave150 trial (IMbrave150 group) and 532 who did not (non‐IMbrave150 group). Results: Median progression‐free survival (PFS) in the IMbrave150 and non‐IMbrave150 groups was 7.4 months and 5.6 months (p = 0.002). Multivariable analysis revealed that non‐B, non‐C HCC aetiology (hazard ratio [HR], 1.173), α‐fetoprotein ≥100 ng/mL (HR, 1.472), Barcelona Clinic Liver Cancer stage ≥ C (HR, 1.318), and modified albumin–bilirubin (mALBI) grade 2b or 3 (HR, 1.476) are independently associated with PFS. Median overall survival (OS) in the IMbrave150 and non‐Imbrave150 groups was 26.5 and 18.8 months (p < 0.001). Multivariable analysis revealed that Eastern Cooperative Oncology Group performance status ≥2 (HR, 1.986), α‐fetoprotein ≥100 ng/mL (HR, 1.481), and mALBI grade 2b or 3 (HR, 2.037) are independently associated with OS. In subgroup analysis, there were no significant differences in PFS or OS between these groups among patients with mALBI grade 1 or 2a. Conclusions: Patients who are treated with Atezo/Bev and meet the inclusion criteria for the phase 3 IMbrave150 trial, as well as those who do not meet the inclusion criteria but have good liver function, have a good prognosis for survival.
