Background: Atezolizumab plus bevacizumab (Ate/Bev) demonstrated promising efficacy and safety in patients with advanced hepatocellular carcinoma (HCC) in the phase III IMbrave150 trial. However, patients with Child–Pugh B HCC were excluded in the abovementioned prospective trial. Therefore, we aimed to investigate the efficacy and safety of Ate/Bev in patients with Child–Pugh B HCC. Methods: This multicenter retrospective study included 36 patients with Child–Pugh B advanced HCC who received Ate/Bev at four cancer referral centers between May 2020 and August 2021. Comparative analyses were performed with an independent cohort of patients with Child–Pugh A HCC from the same registry (n = 133). Results: All patients received Ate/Bev as first-line systemic treatment for advanced HCC. The objective response and disease control rates of patients in the Child–Pugh groups B and A were 11.1% and 58.3% and 34.6% and 76.7%, respectively. The median progression-free survival (PFS) and overall survival (OS) were 3.0 months [95% confidence interval (CI), 1.7–4.3) and 7.7 months (95% CI, 4.8–10.6) in the Child–Pugh B group, whereas the median PFS and OS were 9.6 months (95% CI, 5.1–14.2) and not reached (95% CI, not available) in the Child–Pugh A group, respectively. Compared to the Child–Pugh A group, grade 3–4 adverse events (AEs) were more common in the Child–Pugh B group (44.4% versus 15.8, p < 0.001), with the most frequent grade 3–4 AEs being gastrointestinal bleeding (n = 6, 16.7%), neutropenia (n = 5, 13.9%), and thrombocytopenia (n = 4, 11.1%). Conclusions: In the Child–Pugh B subgroup of patients with advanced HCC, Ate/Bev treatment showed modest clinical activity. However, due to the increased frequency of serious AEs, careful evaluation of treatment response and AE management is required in this subgroup of patients. [ABSTRACT FROM AUTHOR]

Background: Lenvatinib is an approved first-line treatment for unresectable hepatocellular carcinoma (uHCC). We evaluated the safety and efficacy of lenvatinib versus sorafenib in patients with uHCC who deteriorated to Child-Pugh class B (CP-B) on treatment. Methods: We retrospectively evaluated patients from REFLECT who deteriorated to CP-B versus those who remained Child-Pugh class A (CP-A) within 8 weeks after randomization. Best overall response and objective response rate (ORR) per modified Response Evaluation Criteria In Solid Tumors (mRECIST) were assessed from baseline. Progression-free survival (PFS) per mRECIST and overall survival (OS) were assessed beginning at week 8. Results: Patients with CP-B versus CP-A classification receiving lenvatinib had ORRs of 28.3 and 42.9%, respectively; patients with CP-B versus CP-A classification receiving sorafenib had ORRs of 8.5 and 12.9%, respectively. Median PFS and OS (landmark analyses beginning at week 8) in patients receiving lenvatinib were 3.7 months [95% confidence interval (CI): 1.8–7.4] and 6.8 months (95% CI: 2.6–10.3) in the CP-B subgroup versus 6.5 months (95% CI: 5.6–7.4) and 13.3 months (95% CI: 11.6–16.1) in the CP-A subgroup, respectively. Median PFS and OS in patients receiving sorafenib were 0.5 months (95% CI: 0.1–3.6) and 4.5 months (95% CI: 2.9–6.1) in the CP-B subgroup versus 3.6 months (95% CI: 2.7–3.7) and 12.0 months (95% CI: 10.2–14.0) in the CP-A subgroup, respectively. The most common treatment-emergent adverse events in the lenvatinib cohort were hypertension (both subgroups) and decreased appetite (CP-B subgroup). Conclusion: Results suggest that patients with uHCC whose liver function deteriorates to CP-B after initiation of therapy may continue to receive lenvatinib.
