Therapeutic blockade of the programmed cell death protein‐1 (PD‐1) immune checkpoint pathways has resulted in significant reactivation of T cell–mediated antitumor immunity and is a promising clinical anticancer treatment modality in several tumor types, but the durable response rate remains relatively low (15%–20%) in most patients with HCC for unknown reasons. Evidence reveals that the interferon signaling pathway plays a critical role in modulating the efficacy and sensitivity of anti–PD‐1 therapy against multiple tumor types, but the mechanisms are unclear.
