Brief Summary
The goal of this prospective clinical trial is to identify a predictive biomarker in patients with advanced HCC (stage B and C) using a combinatorial approach of the liquid biopsy. The main questions it aims to answer are: * Is multi-omic liquid biopsy approach able to identify a strong predictive biomarker of immunotherapy efficiency? * Is there a correlation between tissue biopsy (PD-L1 tissue level of expression) and liquid biopsy (detection of CTC expressing PD-L1) in HCC patients? Participants blood will be collected at several time points.
