BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) is a prevalent and deadly disease with limited treatment options. Regorafenib, a tyrosine kinase inhibitor, has shown promise in HCC treatment but faces limitations as a monotherapy. Combining regorafenib with PD-1 inhibitor may improve efficacy and survival outcomes for patients. This retrospective analysis was conducted to explore its efficacy and safety, providing reference experience for better application of this combination therapy. METHODS: This retrospective single-center study evaluated the efficacy and safety of combining regorafenib with PD-1 blockade for patients with HCC. Efficacy was evaluated according to the RECIST 1.1 evaluation criteria. Safety was assessed using CTCAE 4.0. Data was analyzed to compare survival status in different subgroups. RESULTS: Generally, there were 76 patients with HCC elected to receive the regorafenib plus PD-1 blockade treatment during the study period. The objective response rate was 21.1% ( = 16), and the disease control rate was 56.6% ( = 43). Median progression-free survival (PFS) was 6.8 months, and median overall survival had not yet been reached. All patients suffered of at least 1 adverse event. Grade ≥3 adverse events occurred in 31.6% of patients ( = 24), with the most common being hand-foot syndrome, decreased appetite, and abdominal distension. Subgroup analyses showed no significant differences in PFS based on cirrhosis status or previous treatment lines. CONCLUSION: With manageable safety, regorafenib combined PD-1 inhibitor could bring survival benefits for advanced HCC who have received systemic treatment. Further, the Cox analysis showed that HBV infection, metastasis, etc. did not have significant effects on the survival benefits.
背景与目的:肝细胞癌(HCC)是一种常见且致命的疾病,治疗选择有限。瑞戈非尼是一种酪氨酸激酶抑制剂,在HCC治疗中显示出前景,但作为单一疗法存在局限性。将瑞戈非尼与PD-1抑制剂联合使用可能会提高患者的疗效和生存结局。进行这项回顾性分析以探讨其疗效和安全性,为更好地应用这种联合疗法提供参考经验。 方法:这项回顾性单中心研究评估了瑞戈非尼与PD-1阻断剂联合治疗HCC患者的疗效和安全性。根据RECIST 1.1评估标准评估疗效。使用CTCAE 4.0评估安全性。分析数据以比较不同亚组的生存状况。 结果:总体而言,在研究期间有76例HCC患者选择接受瑞戈非尼加PD-1阻断治疗。客观缓解率为21.1%(n = 16),疾病控制率为56.6%(n = 43)。中位无进展生存期(PFS)为6.8个月,中位总生存期尚未达到。所有患者均至少发生1次不良事件。31.6%的患者发生≥3级不良事件(n = 24),最常见的是手足综合征、食欲减退和腹胀。亚组分析显示,基于肝硬化状态或既往治疗线数,PFS无显著差异。 结论:瑞戈非尼联合PD-1抑制剂安全性可控,可为接受过全身治疗的晚期HCC患者带来生存获益。此外,Cox分析显示,HBV感染、转移等对生存获益无显著影响。
