Background and Aim: The study goal was to compare the outcomes of patients with unresectable hepatocellular carcinoma (HCC) who received atezolizumab plus bevacizumab (Atezo/Bev) as either first‐ or later‐line systemic therapy. Methods: A total of 430 patients with HCC treated with Atezo/Bev at 22 institutions in Japan were included. Patients treated with Atezo/Bev as first‐line therapy for HCC were defined as the first‐line group (n = 268) while those treated with Atezo/Bev as second‐ or later‐line therapy were defined as the later‐line group (n = 162). Results: The median progression‐free survival times in the first‐ and later‐line groups were 7.7 months (95% confidence interval [CI], 6.7–9.2) and 6.2 months (95% CI, 5.0–7.7) (P = 0.021). Regarding treatment‐related adverse events, hypertension of any grade was more common in the first‐line group than in the later‐line group (P = 0.025). Analysis adjusted by inverse probability weighting, including patient and HCC characteristics, showed that the later‐line group (hazard ratio, 1.304; 95% CI, 1.006–1.690; P = 0.045) was significantly associated with progression‐free survival. In patients with Barcelona Clinic Liver Cancer stage B, the median progression‐free survival times in the first‐ and later‐line groups were 10.5 months (95% CI, 6.8–13.8) and 6.8 months (95% CI, 5.0–9.4) (P = 0.021). Among patients with a history of lenvatinib therapy, the median progression‐free survival times in the first‐ and later‐line groups were 7.7 months (95% CI, 6.3–9.2) and 6.2 months (95% CI, 5.0–7.7) (P = 0.022). Conclusion: The use of Atezo/Bev as first‐line systemic therapy in patients with HCC is expected to prolong survival. [ABSTRACT FROM AUTHOR]
