Abstract

BACKGROUND/AIM: The aim of this study was to investigate the outcomes of atezolizumab plus bevacizumab in patients with advanced hepatocellular carcinoma (HCC), including those with disease refractory to lenvatinib, in clinical practice.

PATIENTS AND METHODS

Of 34 patients treated with atezolizumab plus bevacizumab, a total of 23, including 16 with lenvatinib failure, were enrolled in this retrospective study. The adverse events, changes in liver function and antitumor responses at 6 weeks after starting therapy were evaluated.

RESULTS

The incidence of grade 3 adverse events was low, at 13.0%. Albumin-bilirubin scores did not worsen at 3 and 6 weeks compared to baseline. The objective response rate and disease control rate at 6 weeks were 17.4% and 78.3% according to Response Evaluation Criteria in Solid Tumors (RECIST), and 30.4% and 78.3% according to modified RECIST, respectively.

CONCLUSION

Our results suggest that atezolizumab plus bevacizumab might have potential therapeutic safety and efficacy in patients with advanced HCC, including those with disease refractory to lenvatinib. Further studies are needed to confirm the outcomes of atezolizumab plus bevacizumab after lenvatinib failure.

摘要

背景/目的:本研究旨在探讨在临床实践中,阿替利珠单抗联合贝伐珠单抗治疗晚期肝细胞癌(HCC)患者的疗效,包括对乐伐替尼耐药的患者。

患者与方法

在34例接受阿替利珠单抗联合贝伐珠单抗治疗的患者中,共有23例患者纳入本回顾性研究,其中16例为乐伐替尼治疗失败的患者。评估了治疗开始后6周时的不良事件、肝功能变化和抗肿瘤反应。

结果

3级不良事件的发生率较低,为13.0%。与基线相比,3周和6周时的白蛋白-胆红素评分没有恶化。根据实体瘤疗效评价标准(RECIST),6周时的客观缓解率和疾病控制率分别为17.4%和78.3%;根据改良RECIST标准,分别为30.4%和78.3%。

结论

我们的结果表明,阿替利珠单抗联合贝伐珠单抗可能对晚期HCC患者具有潜在的治疗安全性和疗效,包括对乐伐替尼耐药的患者。需要进一步研究以证实乐伐替尼治疗失败后阿替利珠单抗联合贝伐珠单抗的疗效。
