Description
Summary:Hepatocellular carcinoma (HCC) represents one of the leading contributors to cancer-related deaths, with the majority of patients diagnosed at stages where curative treatment is no longer possible. Combining stereotactic body radiotherapy (SBRT) with immune checkpoint inhibition (ICI) has gained increasing attention as a therapeutic approach. Beyond its ability to provide high local tumor control (LC), SBRT can provoke immunogenic tumor cell death, promote antigen release and presentation, and modulate the tumor microenvironment in ways that enhance systemic antitumor immunity. In this narrative review, we outline the scientific rationale for integrating SBRT with ICIs, discuss mechanistic and translational findings and summarize results from key clinical trials. The currently available data indicate a synergistic interaction, most notably reflected in improved survival and response rates. Nevertheless, variability in dose and fractionation schedules, treatment sequencing, and patient characteristics complicates interpretation. Well-designed prospective studies are needed to establish optimal protocols and identify predictive biomarkers to guide patient selection.
