For the advanced hepatocellular carcinoma (HCC), the targeted therapy and immunotherapy are recommended. This study focused on the management of Lenvatinib combined anti-PD1 antibody for the HCC. This study will create a database that will provide clinical parameters and outcomes of patients undergoing Lenvatinib and anti-PD1 antibody as part of their standard of care in hopes of answering key clinical questions.

Lenvatinib was non-inferior to sorafenib in overall survival in untreated advanced hepatocellular carcinoma. The programmed cell death protein-1 (PD-1) antibody, was effective and tolerable in patients with hepatocellular carcinoma and portal vein tumor thrombus. We aimed to describe the efficacy and safety of Lenvatinib combined anti-PD1 antibody in patients with hepatocellular carcinoma who can not receive redical therapy.
