Real-world effectiveness of lenvatinib monotherapy among unresectable hepatocellular carcinoma patients in the USA.

Aim: This study evaluated the effectiveness of lenvatinib monotherapy for first-line treatment of unresectable hepatocellular carcinoma (uHCC) in a real-world setting. Materials & methods: This retrospective cohort study included patients who initiated lenvatinib monotherapy as first-line treatment for uHCC (n = 233). Clinical outcomes included provider-reported best response, progression-free survival (PFS) and overall survival (OS). PFS and OS were estimated using Kaplan-Meier methods. Results: Most patients (67.8%) were male. A total of 44.6% had Child-Pugh A and 39.1% had Child-Pugh B. Dose reductions were reported in 9%. Median PFS and OS were not reached. At 6 and 12 months, landmark PFS were 85.1 and 64.9%, respectively; landmark OS were 91.8 and 72.6%, respectively. Conclusion: These results affirm the clinical effectiveness of first-line lenvatinib monotherapy in uHCC.
