    Abstract:
    BACKGROUND/AIM: Atezolizumab plus bevacizumab therapy is the new standard treatment option for advanced hepatocellular carcinoma (HCC). The clinical details and sequential course after atezolizumab plus bevacizumab therapy remain to be determined. PATIENTS AND METHODS: Thirty-four consecutive patients who received atezolizumab plus bevacizumab therapy were evaluated. Their clinical outcomes were assessed according to liver function classified by modified albumin-bilirubin (ALBI) grade 1 and 2a (1/2a) versus 2b and treatment line (first-line versus second- or later-line). Furthermore, the treatment sequence after atezolizumab plus bevacizumab therapy was also assessed. RESULTS: The objective response and disease control rates were 15.6% and 93.8%, respectively. The median proportions of ALBI scores at 1, 2, and 3 months relative to the baseline scores were 0.94, 0.97, and 0.93, respectively. The median proportions of α-fetoprotein (AFP) scores at 1, 2, and 3 months relative to the baseline scores were 0.98, 1.12, and 1.83, respectively. There were no significant differences in the changes in the proportions of AFP and ALBI scores according to both liver function and treatment line. Twelve patients were administered lenvatinib treatment after the failure of atezolizumab plus bevacizumab therapy. The proportions of AFP and ALBI scores at 1 month relative to the baseline scores were 0.55 and 0.81, respectively. CONCLUSION: Atezolizumab plus bevacizumab therapy can be effective for advanced HCC irrespective of the patients' liver function and treatment line. Lenvatinib administration after atezolizumab plus bevacizumab therapy can be effective, although special attention should be paid to the deterioration of liver function.
