Purpose Data from common clinical practice were used to generate balanced cohorts of patients receiving either sorafenib or lenvatinib, for unresectable hepatocellular carcinoma, with the final aim to investigate their declared equivalence.Methods Clinical features of lenvatinib and sorafenib patients were balanced through inverse probability of treatment weighting (IPTW) methodology, which weights patients' characteristics and measured outcomes of each patient in both treatment arms. Overall survival was the primary endpoint and occurrence of adverse events was the secondary.Results The analysis included 385 patients who received lenvatinib, and 555 patients who received sorafenib. In the unadjusted cohort, lenvatinib did not show a survival advantage over sorafenib (HR: 0.85, 95% CI 0.70-1.02). After IPTW adjustment, lenvatinib still not returned a survival advantage over sorafenib (HR: 0.82, 95% CI: 0.62-1.07) even in presence of balanced baseline characteristics. Lenvatinib provided longer survival than sorafenib in patients previously submitted to TACE (HR: 0.69), with PS of 0 (HR: 0.73) or without extrahepatic disease (HR: 0.69).Conclusion Present results confirmed randomized controlled trial in the real-life setting, but also suggests that in earlier stages some benefit can be expected.
