Safety and Efficacy of Atezolizumab-Bevacizumab Versus Tyrosin Kinase Inhibitors in Patients With Liver Cirrhosis

Overview

Following the results of the randomized clinical trial IMbrave150, the combination of Atezolizumab with Bevacizumab became the first line regimen for patients with advanced hepatocellular carcinoma and it was approved by the FDA and the EMA. Despite these results, real life data on safety and efficacy of this therapy are still lacking. The unmet needs currently observed are: the safety and efficacy in patients with mild liver decompensation (Child Pugh B class) detected before or during treatment start and the role of liver decompensation compared to TKIs therapy. Liver decompensation is not necessary associated with tumor progression and it may occur in patients with liver cirrhosis. Its prognostic role is not known. in this multicentric observational study the Authors enrolled patients with liver cirrhosis and advanced hepatocellular carcinoma treated with Atezolizumab/Bevacizumab to analyse efficacy, safety compared to a retrospectively collected matched cohort of patients treated with TKIs. Moreover They evaluated the safety and efficacy of Atezolizumab/Bevacizumab according to liver function (detected as Child Pugh score and Albumin-Bilirubin grade), underlying etiology of liver disease, presence or absence of portal hypertension and finally presence or absence of liver decompensation. Furthermore, the Authors evaluated its prognostic role on overall survival and time to progression.
