Proton beam radiotherapy combined with anti-PD1/PDL1 immune checkpoint inhibitors for advanced hepatocellular carcinoma.

ABSTRACT: Anti-Programmed cell Death protein 1 (Anti-PD1) or Programmed Death-Ligand 1 (PDL1) immune checkpoint inhibitors provide treatment options for advanced HCC patients with low response rates. Combination therapy is becoming a major issue to improve the unmet need. Proton beam radiotherapy (PBT) could effectively control the local tumor with a low-risk injury to peripheral liver parenchyma. We retrospectively reviewed the patients who have received PBT combined with anti-PD1/PDL1 to evaluate the efficacy and safety of the advanced HCC patients. This study reviewed 29 advanced HCC patients who have received PBT and anti-PD1/PDL1 during 2016 and 2019. All were Child-Pugh A and performance status 0-1. Seventeen patients (58.6%) had extrahepatic spreading. Concurrent PBT started during anti-PD1/P
