Abstract
Background/aim: Surgical resection remains the only curative treatment for combined hepatocellular-cholangiocarcinoma; however, systemic therapy is the primary treatment option for unresectable cases. This multicenter retrospective study aimed to assess the efficacy of systemic therapy for unresectable combined hepatocellular-cholangiocarcinoma.
Patients and methods: Twenty-one patients with histologically confirmed or clinically diagnosed combined hepatocellular-cholangiocarcinoma who received systemic therapy were included. First-line regimens consisted of lenvatinib (n=14) and atezolizumab plus bevacizumab (n=7) and their therapeutic efficacy was evaluated.
Results: The objective response and disease control rates were 42.9% and 92.9% for lenvatinib, and 14.3% and 100% for atezolizumab plus bevacizumab, respectively. Median overall survival for all treatments was 14.9 months and median progression-free survival was 6.5 months. By regimen, median overall and progression-free survival was 14.9 and 6.1 months for lenvatinib, and "not reached" and 7.9 months for atezolizumab plus bevacizumab, respectively.
Conclusion: Lenvatinib and atezolizumab plus bevacizumab exhibited potential activity in patients with combined hepatocellular-cholangiocarcinoma.
