Evolving Treatment Of Advanced Hepatocellular Carcinoma In The Asia-Pacific Region: A Review And Multidisciplinary Expert Opinion

Simple SummaryFor years, the systemic therapies sorafenib and lenvatinib have represented standard of care for first-line treatment of advanced hepatocellular carcinoma (HCC). The recent approval of atezolizumab in combination with bevacizumab heralded the arrival of immunotherapy for first-line treatment of advanced HCC, and the field is growing, with other combination immunotherapies under investigation. Focusing on the Asia-Pacific region, where drug availability and reimbursement systems differ widely, this article reviews the evolving treatment landscape and summarises the authors' expert opinion on therapeutic decision-making to optimise outcomes in advanced HCC.Hepatocellular carcinoma (HCC) is the fourth most common driver of cancer-related death globally, with an estimated 72% of cases in Asia. For more than a decade, first-line systemic treatments for advanced or unresectable HCC were limited to the multi-targeted kinase inhibitors sorafenib and, more recently, lenvatinib. Now, treatment options have expanded to include immunotherapy, as exemplified by the immune checkpoint inhibitor (ICI) atezolizumab combined with the antiangiogenic agent bevacizumab. Additional combinations of ICIs with kinase inhibitors, other ICIs, or antiangiogenic agents are under investigation, further supporting the new era of immunotherapy for first-line treatment of advanced or unresectable HCC. We describe this evolving landscape and provide expert opinion on therapeutic best practices in the Asia-Pacific region, where different costs of, and patient access to, treatment are a challenge. With the combination of atezolizumab plus bevacizumab likely to become the clinical standard of care, optimising treatment sequence and ensuring patient access to newer therapies remain priorities. Cost containment and treatment sequencing may be facilitated by characterisation of predictive positive and negative biomarkers. With these considerations in mind, this review and expert opinion focused on advanced HCC in the Asia-Pacific region offers perspectives of multiple stakeholders, including physicians, payer systems, and patients.
