Advisory board resolution: The role of the adjuvant atezolizumab plus bevacizumab in patients with hepatocellular carcinoma at high risk of recurrence following surgical resection or ablation

Abstract

MEETING DATE: July 7, 2023ITEMS ON THE AGENDA:1. The role of the adjuvant atezolizumab plus bevacizumab in patients with hepatocellular carcinoma (HCC) at high risk of recurrence following surgical resection or ablation. Profile of the patient who will benefit the most from this therapy.2. To evaluate the prospects for therapeutic options for patients with early HCC in Russia.Liver cancer remains a public health concern globally, with an increasing trend in the number of incident cases worldwide. Early, precise diagnosis and timely treatment contribute to the improvement in overall and relapse-free survival. It is important that the entire arsenal of local treatments (resection, ablation and liver transplantation) can be applied in cases when HCC is detected at a very early and early stage of the disease. Tumour recurrence after surgical treatment or ablation is a complex and underexplored problem in the treatment of patients with HCC. Many factors that can predict the risk of relapse after surgical treatment have been described: tumour size >5 cm, >3 foci, micro- or macrovascular (Vp1-2) invasion, poor degree of tumour differentiation (G3-4). Our advisory board tried to identify the most important risk factors for early relapse, and to determine the role and impact of the results of the first positive clinical trial focused on the issue of early HCC, IMbrave050: a phase 3 trial of adjuvant atezolizumab + bevacizumab vs active surveillance in patients with HCC at high risk of disease recurrence following resection or ablatio.
