Core Tip

Core tip: Trans-arterial chemoembolization and systemic treatment with sorafenib or lenvatinib are the standards of treatment for patients with intermediate and advanced stage hepatocellular carcinoma (HCC). The rise of new current therapeutic modalities such as radioembolization, the combination of antiangiogenic agents with locoregional therapies and other first and second line systemic options, open up a new paradigm for the treatment of HCC. In this dual cohort study, we describe the treatments performed in the real life setting before the approval of these new systemic options. Our real-data outcomes, lower than expected, highlight unmet needs and improvement areas in the daily practice prior to the introduction of new treatments for HCC.
