BACKGROUND/AIM: The combination of bevacizumab and atezolizumab (Bev-Ate) has been established as a standard first-line systemic treatment option for unresectable hepatocellular carcinoma (HCC) since 2020. This study examined the outcomes of HCC patients who received the combination in southern Taiwan. PATIENTS AND METHODS: All patients were enrolled from four hospitals in Taiwan. They received Bev-Ate therapy for unresectable HCC. RESULTS: Thirty-five patients were included; 28 (80%) had Barcelona Clinic Liver Cancer stage C disease. Hepatitis etiology was chronic hepatitis B and C in 63% and 17% of patients, respectively. Eleven (31%) patients had received prior systemic treatment for unresectable HCC. The response rate was 51%, and the disease control rate was 72% for all patients. The median progression-free survival (PFS) and overall survival (OS) was 5.2 and 22.2 months, respectively. For patients who received prior systemic treatment, the efficacy of Bev-Ate in terms of response rates was similar compared with those without prior systemic treatment. Patients who received lower doses of bevacizumab (<15 mg/kg per dose) had non-inferior PFS and OS compared with those receiving a standard dose of bevacizumab. The incidence of proteinuria of all grades (15.8%) was less common when lower doses of bevacizumab were used. CONCLUSION: Real world data from HCC patients in southern Taiwan disclosed that the efficacy outcomes of Bev-Ate treatment were generally consistent with those of clinical trials in other countries. In patients who were exposed to prior systemic treatment or who received lower doses of bevacizumab, the Bev-Ate regimen retained its clinical efficacy.
